The present invention relates generally to electronic mobile devices, especially mobile phones and tablet computers, and, more particularly, to a cooler device for safely storing and cooling electronic mobile devices.
Electronic mobile devices, often referred to simply as mobile devices, are computing devices small enough to hold and operate by hand. Of particular significance of well-known battery-powered electronic mobile devices, such as smartphones or mobile phones and tablet computers that can connect to an Internet. These devices are common in the not only are they battery-powered they will also have flatscreen interface with digital buttons and keyboard or physical buttons along with a physical keyboard. Most such devices are enabled to connect to an Internet and interconnect with other devices. Integrated cameras, digital media players, the ability to place and receive telephone calls, and other capabilities are common. Power to these mobile devices is typically provided by a lithium battery or battery pack. Mobile devices may additionally run mobile operating systems that allow third-party applications to be installed and run.
Electronic mobile devices are inherently and notoriously susceptible to overheating in high ambient temperatures and direct sunlight. This often renders the mobile devices unworkable until cooled to a lower operating temperature. Overheating of a mobile device can also inherently occur when the mobile device is under a high or prolonged workload. Although skilled artisans have developed varieties of cooling devices designed to attempt to cool mobile devices, advances in the field have not been entirely satisfactory, and have yielded cooling devices that are prohibitively expensive, difficult to construct, and mechanically complex, thereby necessitating continued improvement in the art.
According to the principle of the invention, a cooler device for receiving, storing, and cooling an electronic mobile device includes a housing defining and enclosed volume and including a top, a bottom, a cradle, and at least one air-flow conduit. The cradle depends downwardly into the volume from the top of the housing to a base of the cradle in the volume between the top of the housing and the bottom of the housing. The cradle includes an opening at the top of the housing, a volume-facing surface from the top of the housing to and including the base of the cradle, and an inner surface from the top of the housing to and including the base of the cradle defining a storage compartment between the opening of the cradle and the base of the cradle and configured to receive the electronic mobile device therein through the opening of the cradle. The at least one air-flow conduit is coupled between the base of the cradle and the bottom of the housing and includes a continuous volume-facing surface from the base of the cradle to the bottom of the housing, and a continuous inner surface from the base of the cradle to the bottom of the housing and defining an airflow channel coupling the storage compartment of the cradle to an ambient atmosphere outside the housing in gaseous communication. The volume is filled with a refrigerant in direct contact against the volume-facing surface of the cradle and the continuous volume-facing surface of the at least one air-flow conduit. Preferably, the refrigerant envelops a) the cradle from the top of the housing to the base of the cradle, and thereby the volume-facing surface of the cradle from the top of the housing to the base of the cradle, and b) the at least one air-flow conduit from the base of the cradle to the bottom of the housing, and thereby the volume-facing surface of the at least one air-flow conduit from the base of the cradle to the bottom of the housing. The cradle additionally includes a standoff structure for interacting between the base of the cradle and the electronic mobile device for holding the electronic mobile device away from the base of the cradle, when the electronic mobile device is inserted into the storage compartment of the cradle through the opening of the cradle. The standoff structure includes standoff prominences each configured to directly contact the electronic mobile device, when the electronic mobile device is inserted into the storage compartment of the cradle through the opening of the cradle. The standoff prominences are carried by the base of the cradle, and extend upright into the storage compartment of the cradle. The standoff prominences are on either side of the air-flow channel. The standoff prominences are identical in a particular embodiment. The housing has a sufficient rigidity to not collapse. The bottom of the housing defines a ventilation channel that opens downwardly from the air-flow channel and extends from a first end of the housing to a second end of the housing. The ventilation channel has a center that extends from the first end of the housing to the second end of the housing, and the air flow channel opens outwardly to the center of the ventilation channel. The ventilation channel has an inverted U-shape in an exemplary embodiment.

In use, refrigerant 25 is chilled or frozen, such as by placing cooler device 20 in a refrigerator or freezer until refrigerant 25 is chilled or frozen. Since refrigerant 25 surrounds volume-facing surface 101 of cradle 80 and continuous volume-facing surfaces 121 of air-flow conduits 120, the inherent thermally-conductive material characteristic of housing 21 enables the cooling temperature imparted to refrigerant 25 to be efficiently and completely conducted by cradle 80 to into storage compartment 105 and by air-flow conduits 120 to into air-flow channels 123 for keeping storage compartment 105 and air-flow channels 123 maintained in a cool or low temperature condition for a prolonged period of time. After removing cooler device 20 from the refrigerator or freezer, cooler device 20 can be positioned upright from bottom 50 to top 40, such as by positioning platforms A and B against an underlying supporting surface 160 as shown in
As explained above, electronic mobile devices, often referred to simply as mobile devices, are computing devices small enough to hold and operate by hand. Of particular significance are well-known battery-powered electronic mobile devices, such as smartphones or mobile phones and tablet computers that can connect to an Internet. These devices are common in the not only are they battery-powered, they will also have flatscreen interface with digital buttons and keyboard or physical buttons along with a physical keyboard. Most such devices are enabled to connect to an Internet and interconnect with other devices. Integrated cameras, digital media players, the ability to place and receive telephone calls, and other capabilities are common. Power to these mobile devices is typically provided by a lithium battery or battery pack. Mobile devices may additionally run mobile operating systems that allow third-party applications to be installed and run.
Electronic mobile device 160 is generally representative of a standard mobile phone or smartphone described briefly above, which is battery-powered and inherently susceptible to overheating, and customarily flat and thin, and generally rectangular in shape as defined by its perimeter edge 161, defined by opposed, parallel sides 162 and 163 and opposed parallel ends, extending between its flat major surfaces, namely, back surface 166 and its opposed parallel display or user-interface surface 167. Storage compartment 105 is sized to accept and contain mobile device 160 and hold it upright as will now be explained.
In this example, mobile device 160 in
Being so contained upright in storage compartment 105 from edge 162 rested atop protuberances 115 to edge 163 adjacent to opening 100, the chilled or frozen refrigerant 25 in surrounding contact directly against volume-facing surface 101 of cradle 80 and volume-facing surfaces 121 of air-flow conduits 120 inherently chills cradle 80 and air-flow conduits 120. The inherent thermally-conductive material characteristic of housing 21 enables the cooling temperature imparted to refrigerant 25 to be efficiently and completely conducted by cradle 80 to into storage compartment 105 and by air-flow conduits 120 to into air-flow channels 123 for keeping storage compartment 105 and air-flow channels 123 maintained in a cool or low temperature condition for a prolonged period of time for cooling mobile device 160 in storage compartment 105. Since, back surface 166 faces/confronts and is generally coextensive with respect to side wall 110 of cradle 80 and its opposed, parallel display or user-interface surface 167 faces/confronts and is generally coextensive with respect to side wall 111 of cradle 110, surfaces 166 and 167 are directly exposed to and confront the cooling influence of refrigerant 25, back surface 166 from confronting sidewall 110 of cradle 80 and display or user-interface surface 167 from confronting sidewall 111 of cradle 80. This positioning of mobile device 160 in storage compartment 105 of cradle 80 directly cools of mobile device 160 at its major surfaces, back surface 166 from confronting sidewall 110 of cradle 80 and display or user-interface surface 167 from confronting sidewall 111 of cradle 80, which inherently efficiently cools mobile device 160.
The coupling of storage compartment 105 of cradle 80 in gaseous communication with the ambient atmosphere outside housing 21 by air-flow channels 123 that open downwardly to ventilation channel 150 enables ambient air outside housing 21 to circulate through storage compartment 105 and air-flow channels 120 between opening 100 to into storage compartment and air-flow channels 123 that open downwardly to ventilation channel 150 in response to an inherently temperature differential between the ambient atmosphere outside housing 21 and the comparatively chilled storage compartment 105 and air-flow channels 123. The ambient air can inherently circulate through storage compartment 105 and air-flow channels 120 from opening 100 to ventilation channel 150 through air-flow channels 123, or from ventilation channel 150 through air-flow channels 123 to opening 100. As the air circulates through storage compartment 105 and air-flow channels 123, the circulating air is inherently cooled in storage compartment 105 and air-flow channels 123 by the influence of refrigerant 25 and circulates around mobile device 160 in storage compartment 105, which quickly and efficiently cools mobile device 160. This circulation of ambient air from the ambient atmosphere outside housing 21 through storage compartment 105 and air-flow channels 123 that open downwardly to ventilation channel 150 and air ventilation through ventilation channel 150 inherently develops and moves chilled air through storage compartment 105 and air-flow channels 123 for quickly and efficiently cooling mobile device 160 in storage compartment. At the same time, the circulating air through storage compartment 105 and air-flow channels 123 inherently evaporates condensation from the ambient air that can inherently collect on chilled inner surface 122 of cradle 80 and continuous inner surfaces 122 of air-flow conduits 120. Ventilation channel 150 that opens downwardly from air-flow channels 123 and that extends along the length of housing 21 from the end of housing 21 defined by end wall 62 to the end of housing 21 defined by end wall 63 advantageously enables air to translate therethrough without restriction to enable air circulation between the ambient atmosphere outside of bottom 50 and through storage compartment 105 and air-flow channels 123.
Air-flow conduits 120 are additionally drains by which condensation that develops on inner surface 122 of cradle 80 drains downwardly through air-flow channels 123 by gravity from storage compartment 105 to outwardly through bottom 50, which helps to keep mobile device 160 dry and free from condensed moisture in storage compartment 80. Because protuberances 115 hold mobile device 160 above base 93 and disable it from directing contacting base 93, mobile phone 160 is held upwardly away from base 93 thereby disabling mobile phone 160 from sitting in condensation that may develop on inner surface 122 of base 93 and becoming water damaged.
Since side 163 is located proximate to opening 100 of compartment 105, side 163 may be easily taken up by hand for withdrawing mobile device 160 from storage compartment 105 as desired. Mobile device 160 may be repeatedly installed into and withdrawn from storage compartment 105 for cooling mobile device 160 as needed. Cooler device 20 may also be repeatedly placed into a refrigerator or freezer as desired for chilling or freezing refrigerant 25 for repeated use.
