1. Technical Field
The present disclosure relates to a heat dissipation device.
2. Description of Related Art
With the continuing development of electronic technology, memories generate more heat during operation than previously. The heat should be dissipated as quickly as possible. In some cases, two metallic cooling fins are added to opposite sides of each memory to dissipate heat therefrom. However, this method makes maintenance difficult as it is inconvenient to disassemble the cooling fins.
Many aspects of the present embodiments can be better understood with reference 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 present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. 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 clamp 10 is substantially U-shaped, and includes a substantially rectangular top plate 12 and two lateral plates 14 extending down from opposite sides of the top plate 12. The top plate 12 is convex in cross section, forming a shallow trough along the length thereof. A top of each lateral plate 14 forms an arc-shaped connection portion 16 connected to the corresponding side of the top plate 12, which is convenient to deform the lateral plates 14 relative to the top plate 12. Two substantially L-shaped latches 140 substantially perpendicularly extend from opposite ends of a bottom of an outer surface of each lateral plate 14. Each latch 140 and the corresponding lateral plate 14 bound a slot 142 along a length of the lateral plate 14.
Each fastener 20 is made of elastic material, and includes a substantially U-shaped main body 22 and two pivot pins 224 substantially perpendicularly extending from opposite distal ends of the main body 22. The main body 22 includes a long resisting pole 220 and two connection poles 222 substantially perpendicularly extending up from opposite ends of the resisting pole 220. Each pivot pin 224 substantially extends from a distal end of a corresponding connection pole 222 opposite to the resisting pole 220, away from the other connection pole 222.
The first cooling fin 30 is substantially rectangular. Two first pivot tabs 32 substantially perpendicularly extend from opposite ends of a top side of the first cooling fin 30, facing the second cooling fin 40. A pivot pin 320 extends from an inner end of each pivot tab 32, along a length of the first cooling fin 30 and toward the other pivot tab 32. Two blocks 34 extend from an outer surface of the first cooling fin 30, away from the second cooling fin 40. Each block 34 defines a pivot hole 340 extending along the length of the first cooling fin 30.
The second cooling fin 40 is substantially rectangular. Two second pivot tabs 42 substantially perpendicularly extend from opposite ends of a top side of the second cooling fin 40, facing the first cooling fin 30. Each second pivot tab 42 defines a pivot hole 420 in an outer end of the second pivot tap 42, along a length of the second cooling fin 40 and opposite to the other second pivot tab 42. Two blocks 44 extend from an outer surface of the second cooling fin 40, away from the first cooling fin 30. Each block 44 defines a pivot hole 440 extending along the length of the second cooling fin 40.
Referring to
In disassembly, the resisting poles 220 of the fasteners 20 are deformed away from the slots 142 of the lateral plates 14. The connection portions 16 of the lateral plates 14 are deformed to move the lateral plates 14 away from each other. Therefore, the clamp 10 is readily to be removed, and then the first and second cooling fins 30 and 40 can be easily disassembled from the memory 100.
In this embodiment, the curvature of the top plate 12 makes the top plate 12 easily deformed and can guide the lateral plates 14 deformed along predetermined direction when the lateral plates 14 are deformed away from each other.
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 present disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
