Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

Network 150 and its various components may be implemented using hardware, software, or any combination thereof.


In one embodiment, each sensor 140 (collectively referred to herein as “sensors 140”) may be a suitable system, apparatus, or device operable to capture information associated with information handling system 100. In particular, sensors 140 may be disposed throughout information handling system 100 (e.g., within sound field chamber 200 shown in FIGS. 2A-2C) and/or computing environment 155 such that sensors 140 may capture environmental information associated with physical parameters of information handling system 100 (e.g., humidity level, corrosion level, and the like). In one embodiment, sensors 140 may be or include one or more humidity sensors and/or corrosion sensors operable to, both, capture environmental information associated with information handling system 100 and to transmit the captured environmental information to one or more devices of information handling system 100 for analysis. In other embodiments, sensors 140 may be or include one or more motion sensors, power failure sensors, voltage sensors, current sensors, smoke sensors, and/or any combination of sensors suitable for capturing information associated with information handling system 100.


In one embodiment, sensors 140 may be or include one or more humidity sensors operable to measure an amount of water vapor, or a “humidity level,” present in information handling system 100. In this embodiment, sensors 140 may capture the humidity level of information handling system 100 and may transmit the captured humidity level to one or more devices of information handling system 100 for analysis. For example, sensors 140 may be or include one or more hygrometers operable to capture data indicating a humidity level, or “humidity level data,” present within one or more chassis of information handling system 100 and to transmit the captured humidity level data to humidity controller 110. Humidity controller 110 may receive the humidity level data from sensors 140 and may determine a humidity level of information handling system based on the humidity level data, accordingly.


In one embodiment, sensors 140 may be or include one or more corrosion sensors operable to measure a rate of corrosion, or a “corrosion level,” present in information handling system 100. In this embodiment, sensors 140 may capture the corrosion level of information handling system 100 and may transmit the captured corrosion level to one or more devices of information handling system 100 for analysis. For example, sensors 140 may be or include one or more corrosion sensors operable to capture data indicating a corrosion level, or “corrosion level data,” present within one or more printed circuit boards (PCBs) and/or devices within, or communicably coupled to, information handling system 100 and to transmit the captured corrosion level data to humidity controller 110. Humidity controller 110 may receive the corrosion level data from sensors 140 and may determine a corrosion level of information handling system based on the corrosion level data, accordingly.


In one embodiment, each fan 145 (collectively referred to herein as “fans 145”) may be a suitable system, apparatus, or device operable to cause airflow within information handling system 100. In particular, fans 145 may be disposed throughout information handling system 100 such that fans 145 may be activated, or otherwise placed in an on state, to increase and/or decrease airflow to components and/or a temperature of the components within information handling system 100. Similarly, fans 145 may be deactivated, or otherwise placed in an off state, to increase and/or decrease airflow to components and/or a temperature of the components within information handling system 100. In one embodiment, fans 145 may be disposed proximate to an inlet of information handling system 100 to cause an incoming airflow to enter information handling system 100 via the inlet. For example, fan 145 may be disposed proximate to inlet 220 illustrated in FIGS. 2A, 2B, and/or 2C to cause an incoming airflow to be received by a sound field chamber 200 coupled to information handling system 100. In one embodiment, fans 145 may be or include one or more server rack enclosure fans. In other embodiments, fans 145 may be or include rack mount fan trays, case fans, power supply unit (PSU) fans, central processing unit (CPU) fans, hard drive cooling fans, and/or any combination of fans suitable for causing airflow within information handling system 100.


In one embodiment, sound source 105 may be a suitable system, apparatus, or device operable to cause a humidity level within an incoming airflow received by information handling system 100 to be reduced. In particular, sound source 105 may be or include one or more electroacoustic transducers operable to generate a sound field causing an acoustic agglomeration in water vapor comprising the humidity level, thereby causing the humidity level in the incoming airflow to decrease. Specifically, water molecules comprising the water vapor may coalesce into clusters, or droplets, in response to prolonged exposure to sound waves (e.g., progressive sound waves, reflected sound waves, and/or combinations of progressive and reflected sound waves) within the sound field generated by sound source 105. That is, water vapor within the incoming airflow may become entrained in the sound field, collide, and may begin to condense to form small droplets of water. The small droplets may continue to increase in size with exposure to the sound field. As the droplets increase in size, gravity may cause the droplets to fall, thereby removing the water vapor from the incoming airflow and decreasing the humidity level therein. In one embodiment, sound source 105 may be or include a loudspeaker disposed within an acoustic chamber (e.g., sound field chamber 200 shown in FIGS. 2A-2C). In other embodiments, sound source 105 may be or include a midrange speaker, ultrasonic speaker, high-frequency speaker, low-frequency speaker, piezoelectric speaker, and/or any other type of sound source suitable for generating a sound field comprised of sound waves to cause an acoustic agglomeration in water vapor. Sound source 105 is described in further detail with respect to FIGS. 2A-3.


In one embodiment, humidity controller 110 may be a suitable system, apparatus, or device operable to manage a humidity level in information handling system 100. In particular, humidity controller 110 may cause a decrease in a humidity level in information handling system 100 to reduce corrosion of one or more devices disposed, or otherwise installed, within information handling system 100. Conventionally, fresh air cooling methods used to decrease the ambient temperature of an information handling system may direct an outdoor air stream through the information handling system, thereby cooling the information handling system as the outdoor air stream flows. However, outdoor air streams may carry high levels of humidity, causing water within the outdoor air streams to condense and form multiple layers of water that adhere to various devices within the information handling system. Specifically, outdoor air streams having a high RH (e.g., greater than 50% RH) may cause multiple monolayers of water to coat the surfaces of various devices (e.g., PCBs, microcontrollers, FPGAs, CPLDs, and the like) within the information handling systems. In polluted environments, the outdoor air streams may additionally carry gaseous pollutants (e.g., C12, H2S, SO2, O3, and the like), causing pollutant molecules within the outdoor air streams to become absorbed into the multiple layers of water coating devices within the information handling system. This may result in corrosion of the devices over time, which may cause nondeterministic behavior in the devices and eventual failure. Replacing corroded devices may require increased cost and maintenance for users, thereby decreasing user experience and overall system efficiency.


In contrast, humidity controller 110 may mitigate the increased humidity levels associated with fresh air cooling methods to reduce corrosion in information handling system 100. In particular, humidity controller 110 may identify a humidity level (e.g., captured by sensors 140) of an incoming airflow received by information handling system 100 and may then determine whether the humidity level is greater than, or equal to, a humidity level in which corrosion may occur, or a “threshold humidity level.” In one embodiment, the threshold humidity level may be or include a numerical value indicating a specific humidity in grams of water vapor per kilogram of air (g.kg-1). In another embodiment, the threshold humidity level may be or include a numerical value indicating an absolute humidity in grams of water vapor per cubic meter of air (g.m-3). In yet another embodiment, the threshold humidity level may be or include an RH percentage comprised of a ratio between a quantity of moisture in the air (i.e., actual water vapor density) to the maximum quantity of moisture the air can withstand (i.e., saturation water vapor density). For example, a threshold humidity level may be or include an RH percentage of 50%. In one embodiment, the threshold humidity level may be stored in one or more memory devices of information handling system 100. For example, the threshold humidity level may be stored in local storage resource 130 such that humidity controller 110 may access local storage resource 130 to identify the threshold humidity level in response to receiving humidity level data from sensors 140. In another embodiment, the threshold humidity level may be stored in a memory device local to, or within, humidity controller 110.


In one embodiment, humidity controller 110 may determine whether the humidity level of an incoming airflow used to cool one or more devices disposed, or otherwise installed, within information handling system 100 is greater than, or equal to, the threshold humidity level. In particular, humidity controller 110 may receive humidity level data from sensors 140 and may determine the humidity level of information handling system 100 based on the humidity level data. Humidity controller 110 may then access one or more memory devices of information handling system 100 (e.g., memory subsystem 120, local storage resource 130, local memory device within humidity controller 110, and the like) to identify the threshold humidity level. Humidity controller 110 may then compare the humidity level of information handling system 100 to the threshold humidity level to determine whether the incoming airflow includes a humidity level that is greater than, or equal to, the threshold humidity level. For example, humidity controller 110 may execute one or more mathematical operations to compare the humidity level to the threshold humidity level to determine whether the humidity level is greater than, or equal to, the threshold humidity level.


In one embodiment, humidity controller 110 may cause sound source 105 to generate a sound field within information handling system 100 in response to determining that the humidity level is greater than, or equal to, the threshold humidity level. In particular, humidity controller 110 may access one or more memory devices (e.g., memory subsystem 120, local storage resource 130, local memory device within humidity controller 110, and the like) to identify parameters indicating a frequency, or an “acoustic frequency,” and/or an amplitude, or a “sound pressure level,” at which the sound field is to be generated. For example, humidity controller 110 may access a library of numeric parameters, or settings, stored in local storage resource 130 indicating an acoustic frequency (numeric parameter having Hz units) and/or a sound pressure level (numeric parameter having Pa units) at which sound source 105 may generate a sound field. In one embodiment, acoustic frequency and/or sound pressure level parameters may be indicated to an administrator and/or manufacturer (e.g., a manufacturer of information handling system 100) by a user and/or business enterprise based on specific humidity levels present within information handling systems used by the user and/or business enterprise. For example, a small business enterprise located in the United States may include a single information handling system 100 that receives incoming airflow having low humidity levels. In this example, the small business enterprise may indicate to an administrator and/or manufacturer that a high, and/or ultrasonic, acoustic frequency and/or low sound pressure level may suffice in decreasing humidity levels below threshold humidity levels in the incoming airflow received by the single information handling system 100. In contrast, a large business enterprise located in India may include several information handling systems 100 that each receive incoming airflow having high humidity levels. In this example, the large business enterprise may indicate to an administrator and/or manufacturer that a low acoustic frequency and/or high sound pressure level may be required to decrease humidity levels below threshold humidity levels in incoming airflow received by each of the several information handling systems 100.


In one embodiment, humidity controller 110 may cause sound source 105 to generate the sound field based on the acoustic frequency and the sound pressure level. The sound field may cause an acoustic agglomeration of the water vapor comprising the humidity level of the incoming airflow. The acoustic agglomeration may cause the humidity level to decrease, thereby mitigating the formation of water layers—and pollutant molecules therein—that collect on devices within information handling system 100. For example, the acoustic agglomeration may cause the humidity level to decrease by approximately 70-80% within an incoming airflow. By mitigating increases in humidity levels and reducing corrosion, humidity controller 110 may increase the lifecycle of information handling system 100, thereby decreasing the cost and maintenance associated with replacing corroded devices while increasing user experience and overall system efficiency. Humidity controller 110 is described in further detail with respect to FIGS. 2A-3.



FIGS. 2A, 2B, and 2C are block diagrams of selected elements of embodiments of sound field chambers coupled to an information handling system. Specifically, FIG. 2A illustrates a top view of a sound field chamber 200 coupled to information handling system 100 that includes an ultrasonic sound source 105. FIG. 2B illustrates a top view of a sound field chamber 200 coupled to information handling system 100 that includes a high-frequency sound source 105. FIG. 2C illustrates a top view of a sound field chamber 200 coupled to information handling system 100 (not shown in figure) that includes a low-frequency sound source 105. Other embodiments of sound field chambers 200 may include additional, fewer, and/or different components than the components shown in the embodiment illustrated in FIGS. 2A-2C.


In the embodiment illustrated in FIG. 2A, sound field chamber 200 includes an inlet 220, a sound source 105, a dividing wall 230, and an outlet 250. Sound field chamber 200 may receive incoming airflow 210 via inlet 220. For example, inlet 220 may include one or more fans 145 (shown in FIG. 1) operable to draw in surrounding air to generate incoming airflow 210. In this embodiment, incoming airflow 210 may include a humidity level corresponding to an amount of water vapor in the incoming airflow that may cause corrosion of devices over time, which may cause nondeterministic behavior in the devices and eventual failure. Humidity controller 110 may identify the humidity level of incoming airflow 210 based on humidity level data captured by sensors 140 (shown in FIG. 1) and may determine whether the humidity level is greater than, or equal to, the threshold humidity level as described above with respect to FIG. 1. In response to determining that the humidity level is greater than, or equal to, the threshold humidity level, humidity controller 110 may cause sound source 105 to generate a sound field comprised of sound waves 240.


In the embodiment illustrated in FIG. 2A, sound source 105 may generate an ultrasonic frequency (e.g., greater than 20 kHz). Such ultrasonic frequencies may be inaudible to users, therefore allowing for minimal architecture within sound field chamber 200. As shown in FIG. 2A, the incoming airflow 210 passes through the sound waves 240 within the sound field chamber 200. In response to exposure to the sound waves 240, water vapor within the incoming airflow 210 may become entrained in the sound field, collide, and may begin to condense to form small droplets of water. The small droplets may continue to increase in size with exposure to the sound field. To prolong exposure to the sound waves 240, sound field chamber 200 includes dividing wall 230 to cause the incoming airflow 210 to follow an increased path length as the sound waves 240 cause acoustic agglomeration within the incoming airflow 210. As droplets within the incoming airflow 210 increase in size, gravity may cause the droplets to fall, thereby removing the water vapor from the incoming airflow 210 and decreasing the humidity level therein. As such, outgoing airflow 260 may be supplied to information handling system 100 via outlet 250 such that humidity levels within information handling system 100 may be maintained below the threshold humidity level (e.g., less than 50% RH).


In the embodiment illustrated in FIG. 2B, sound field chamber 200 includes an inlet 220, a sound source 105, a dividing wall 230, and an outlet 250 as described above with respect to FIG. 2A. However, in the embodiment illustrated in FIG. 2B, sound source 105 may generate a high frequency (e.g., 10-20 kHz). Such high frequencies may be audible to users, therefore requiring additional architecture within sound field chamber 200 to suppress the audible high frequencies generated by sound source 105. This is shown in FIG. 2B where sound field chamber 200 includes side branch resonators 270 disposed along two inside surfaces of sound field chamber 200 to attenuate sound waves 240 within the sound field chamber 200 such that the sound waves 240 may be attenuated substantially. As described above with respect to FIG. 2A, water vapor within the incoming airflow 210 may become entrained in the sound field, collide, and may begin to condense to form small droplets of water. The small droplets may continue to increase in size with exposure to the sound field. To prolong exposure to the sound waves 240, sound field chamber 200 includes dividing wall 230 to cause the incoming airflow 210 to follow an increased path length as the sound waves 240 cause acoustic agglomeration within the incoming airflow 210. As droplets within the incoming airflow 210 increase in size, gravity may cause the droplets to fall, thereby removing the water vapor from the incoming airflow 210 and decreasing the humidity level therein. As such, outgoing airflow 260 may be supplied to information handling system 100 via outlet 250 such that humidity levels within information handling system 100 may be maintained below the threshold humidity level (e.g., less than 50% RH).


In the embodiment illustrated in FIG. 2C, sound field chamber 200 includes an inlet 220, a sound source 105, a dividing wall 230, and an outlet 250 as described above with respect to FIG. 2A. However, in the embodiment illustrated in FIG. 2C, sound source 105 may generate a low frequency (e.g., less than 5 kHz). Such low frequencies may be audible and/or distracting to users, therefore requiring additional architecture within sound field chamber 200 to suppress the audible low frequencies generated by sound source 105. This is shown in FIG. 2C where sound field chamber 200 includes side branch resonators 270 disposed along two inside surfaces of sound field chamber 200 to attenuate sound waves 240 within the sound field chamber 200 such that the sound waves 240 may be attenuated substantially. In addition, sound field chamber 200 includes several passive mufflers 280 disposed proximate to inlet 220 and outlet 250. In one embodiment, passive mufflers 280 may be or include a foam material operable to further muffle, or suppress, the audible low frequencies generated by sound source 105. As shown in FIG. 2C, sound field chamber 200 may additionally include an encased air passage 290 such that outgoing airflow 260 may enter the encased air passage 290 via outlet 250. The encased air passage 290 may be lined, or otherwise encased, with passive mufflers 280 to attenuate the amplitude of audible low frequencies exiting sound field chamber 200 as the outgoing airflow 260 travels within the encased air passage 290 to be received by one or more information handling systems 100.


As described above with respect to FIG. 2A, water vapor within the incoming airflow 210 may become entrained in the sound field, collide, and may begin to condense to form small droplets of water. The small droplets may continue to increase in size with exposure to the sound field. To prolong exposure to the sound waves 240, sound field chamber 200 includes dividing wall 230 to cause the incoming airflow 210 to follow an increased path length as the sound waves 240 cause acoustic agglomeration within the incoming airflow 210. As droplets within the incoming airflow 210 increase in size, gravity may cause the droplets to fall, thereby removing the water vapor from the incoming airflow 210 and decreasing the humidity level therein. As such, outgoing airflow 260 may be supplied to information handling system 100 via outlet 250 such that humidity levels within information handling system 100 may be maintained below the threshold humidity level (e.g., less than 50% RH). Specifically, outgoing airflow 260 may pass vertically (as indicated by the outward arrow representing outgoing airflow 260 within encased air passage 290) through encased air passage 290 to be distributed to one or more information handling systems 100. For example, sound field chamber 200 may be disposed underneath one or more information handling systems 100 (i.e., under the floor) of a business enterprise such that outgoing airflow 260 may be distributed to each of the one or more information handling systems 100 above via encased air passage 290.



FIG. 3 is a block diagram of selected elements of an embodiment of a sound field chamber that includes one or more condensation structures. In particular, FIG. 3 illustrates a side view of sound field chamber 200 (e.g., shown in FIGS. 2A, 2B, and 2C) that includes one or more condensation structures 300-A through 300-E (collectively referred to herein as “condensation structures 300”) disposed throughout sound field chamber 200. Each condensation structure 300 may be or include a rigid, hydrophilic material operable to cause a condensation in water vapor within incoming airflow 210 as the incoming airflow 210 passes through sound field chamber 200. That is, each condensation structure 300 may be disposed vertically and angled slightly (e.g., approximately 80° relative to drain 310) within sound field chamber 200 to accommodate variations in droplet size distributions and acoustic frequencies. Specifically, each condensation structure 300 may be angled slightly in relation to sound source 105 to increase exposure areas in the sound field onto which droplets may condensate. As shown in FIG. 3, sound field chamber 200 may additionally include a drain 310 disposed on a bottom surface of sound field chamber 200 to receive droplets that have formed on condensation structures 300 and have fallen from the incoming airflow 210 due to gravity, thereby removing the water vapor from the incoming airflow 210 and decreasing the humidity level therein. In one embodiment, drain 310 may route the collected droplets out of sound field chamber 200 and/or information handling system 100 such that the collected droplets may evaporate in the surrounding computing environment 155.



FIG. 4 is a flowchart depicting selected elements of an embodiment of a method for decreasing a humidity level in an information handling system. It is noted that certain operations described in method 400 may be optional or may be rearranged in different embodiments.


Method 400 may begin at step 410, where a sound field chamber of the information handling system receives an incoming airflow. The incoming airflow may include a humidity level corresponding to an amount of water vapor in the incoming airflow. For example, sound field chamber 200 may receive incoming airflow 210 via inlet 220 as described above with respect to FIG. 2A. The incoming airflow 210 may include a humidity level corresponding to an amount of water vapor in the incoming airflow that may cause corrosion of devices over time, which may cause nondeterministic behavior in the devices and eventual failure as described above with respect to FIG. 2A. At step 420, a humidity controller of the information handling system may identify the humidity level of the incoming airflow. For example, humidity controller 110 may identify the humidity level of incoming airflow 210 based on humidity level data captured by sensors 140 as described above with respect to FIG. 2A. At step 430, the humidity controller may determine that the humidity level is greater than a threshold humidity level. For example, humidity controller 110 may execute one or more mathematical operations to compare the humidity level to the threshold humidity level to determine whether the humidity level is greater than, or equal to, the threshold humidity level as described above with respect to FIG. 1. At step 440, the humidity controller may cause a sound source of the information handling system to generate a sound field within the sound field chamber. The sound field may be comprised of sound waves. The sound waves may cause an acoustic agglomeration of the water vapor. The acoustic agglomeration may cause the humidity level in the incoming airflow to decrease. For example, in response to determining that the humidity level is greater than, or equal to, the threshold humidity level, humidity controller 110 may cause sound source 105 to generate a sound field comprised of sound waves 240 (i.e., progressive sound waves, reflected sound waves, and/or combinations of progressive and reflected sound waves) as described above with respect to FIG. 2A. Each sound pressure wave may cause an acoustic agglomeration of the water vapor comprising the humidity level of the incoming airflow as described above with respect to FIG. 1. The acoustic agglomeration may cause the humidity level to decrease, thereby mitigating the formation of water layers—and pollutant molecules therein—that collect on devices within information handling system 100 as described above with respect to FIG. 1.
