1. Technical Field
The present disclosure relates to a heat dissipation system and an electronic device using the system.
2. Description of Related Art
Electronic components, such as central processing units (CPUs), generate heat during normal operation, which can deteriorate their operational stability, and damage associated electronic components. Thus, the heat must be removed quickly to ensure normal operation of the CPU. An electronic device such as a server utilizing multiple heat-generating components such as CPUs therein requires a powerful heat dissipation system. The heat dissipation system for the server often includes a plurality of fans mounted inside of the server accelerating airflow therethrough. However, the heat dissipation system is inherently mounted in the server, whereby when the server requires updating or replacement, the heat dissipation system must be abandoned accordingly.
What is needed, therefore, is a heat dissipation system can be reused in multiple servers.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The heat dissipation system 10 includes a plurality of fans 12 and a fan holder 14 securing the fans 12 to an outer side of the server 20 to generate airflow. The fans 12 are axial flow fans and generate airflow in a direction parallel to the rotation axes thereof. Each fan 12 has an air inlet and an air outlet for airflow. The air inlets or outlets of the fans 12 fully communicate with an inner cavity of the server 20 through the fan holder 10.
The fan holder 14 comprises a mounting plate 140 attached to the outer side of the server 20 and a framework 142 fixed on an outer side of the mounting plate 140. In this embodiment of the disclosure, the mounting plate 140 is attached to and wholly covers a rear side of the server 20 which is hollow to allow airflow generated by the fans 10 therethrough. A plurality of vents 141 is defined in the mounting plate 140 and arranged evenly in a line on the rear side of the server 20. A plurality of pane units 144 are formed in the framework 142 and arranged in a line continuously along the rear side of the server 20. Each vent 141 in the mounting plate 140 corresponds to one pane unit 144 and enables the pane unit 144 to communicate with a cavity inside the server 20 through the vent 141 and the rear side of the server 20. Each vent 141 is circular and is of a size similar to the air outlet or inlet of the fan 12.
In use, the fans 12, fitted in the pane units 144 of the framework 142 and abutting an outer side of the mounting plate 140, face the vents 141 of the mounting plate 140 and generate airflow into or from the server 20 through the vents 141. Each pane unit 144 has a configuration and size consistent with that of the fan 12, securely accommodating one thereof. The fans 12 mounted outside of the server 20 easily generate airflow through the server 20, exhausting heat generated thereby to the exterior, thus lowering internal temperature of the server 20.
Referring to
According to the disclosure, a heat dissipation system is detachably coupled to one side of a server and can be reused with a different server when removed from the original server. In addition, fans mounted outside of the server by the fan holder 14 can be replaced as needed to increase airflow in the server with no need for available space consideration inside the server.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
