[0003] In the prior art, the heat sinks used in source modules include finned aluminum heat sinks, air-cooled heat sinks, and water-cooled heat sinks, or a combination thereof. Finned aluminum heat sinks, as heat-conducting devices, offer strong heat dissipation capabilities and are widely used in heat dissipation devices. To further enhance heat dissipation performance, the combination of an aluminum heat sink and a fan significantly improves heat dissipation efficiency. Water-cooled heat sinks are more expensive and have a smaller application range than aluminum heat sinks and fan combinations.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the scope of protection of the present invention. Obviously, the embodiments described in the present invention are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1: The specific structure of the utility model is as follows:

[0029] Please refer to the attached Figure 1-2 The utility model is a power supply device with a detachable heat sink structure, comprising a power supply body 2, the power supply body 2 also comprising a housing, the housing is an aluminum housing, on which a plurality of terminal interfaces 11 are mounted. Figure 1 As can be seen from the figure, the casing of the present invention is a rectangular parallelepiped structure.

[0030] A receiving cavity 10 with an opening and a pushing mechanism arranged in the receiving cavity 10 are provided at one position of the power supply body 2. The receiving cavity 10 is provided in the front area of ​​the right end of the casing. The pushing mechanism is provided with a contact power supply contact 4; the power supply body 2 is provided with an air inlet 1 at a position away from the receiving cavity 10, and the air inlet 1 is provided in the left area of ​​the top of the casing. An air passage is provided between the air inlet 1 and the receiving cavity 10. The air passage is the space in the casing other than the motherboard and the battery, and this space connects the air inlet 1 and the receiving cavity 10. The power supply device also includes an air-cooled radiator 8, which can be placed in the receiving cavity 10 and compressed against the pushing mechanism; after the air-cooled radiator 8 is placed in the receiving cavity 10, it forms an electrical conduction structure with the contact power supply contact 4; the air-cooled radiator 8 can be detachably installed in the receiving cavity 10.

[0031] Both sides of the opening are provided with notches 7, and both sides of the air outlet end of the air-cooling radiator 8 are provided with side ears 9 corresponding to the two notches 7. The two side ears 9 are correspondingly placed in the two notches 7 and fixed by screws.

[0032] Specifically, the pushing mechanism of the present invention includes: at least two guide rods 6 fixed in the receiving cavity 10 , a pushing plate 3 movably sleeved on each guide rod 6 , and a spring 5 sleeved on each guide rod 6 .

[0033] Preferably, two guide rods 6 are provided, and the two guide rods 6 are fixed on both sides of the upper space of the receiving chamber 10, and the two guide rods 6 are arranged in parallel, the inner end of the guide rod 6 is provided with a socket hole, and the outer end is provided with a threaded opening. The side of the interior of the receiving chamber 10 facing the opening is provided with two bosses, and the two bosses are opposite to two step holes, and the outer ends of the step holes are threads. The two guide rods 6 are inserted into the two step holes and are limited by the perforated machine screws, and then are connected to the threaded openings of the guide rods 6 by screws passing through the machine screws. Before installing the guide rods 6, it is necessary to put on the spring 5 and the push plate 3.

[0034] The contact power contact 4 is disposed on the surface of the push plate 3, which faces the opening of the receiving cavity 10. A buffer wire is welded to the rear end of the contact power contact 4. The buffer wire is relatively long, and its length meets the maximum travel distance of the push plate 3. The plug end of the air-cooled radiator 8 is provided with contact terminals corresponding to the contact power contact 4. Because the push plate 3 is supported by the spring 5, the contact power contact 4 and the contact terminal are in stable contact, thereby ensuring stable power supply to the air-cooled radiator 8.

[0035] One end of each spring 5 faces the push plate 3, and the other end of each spring 5 rests against the side of the receiving cavity 10 facing the opening. When installing the air-cooled radiator 8 of the present invention, it is necessary to apply force to push the air-cooled radiator 8 into the receiving cavity 10, thereby causing the push plate 3 to retreat and the two springs 5 ​​to compress. When the air-cooled radiator 8 is fully inserted into the receiving cavity 10, the two side ears 9 fit neatly into the two notches 7. The side ears 9 are then fixed with screws, completing the installation of the air-cooled radiator 8.

[0036] Example 2:

[0037] Disassembling the air-cooled radiator 8: Since the length of the spring 5 when not under force is sufficient to push a local area of ​​the air-cooled radiator 8 out of the opening, when disassembling the air-cooled radiator 8, press the air-cooled radiator 8, unscrew the screws on the two side ears 9, and then loosen the air-cooled radiator 8. The compressed spring 5 pushes out the push plate 3, and the push plate 3 pushes the air-cooled radiator 8 out of a distance, so that a local area of ​​the air-cooled radiator 8 extends out of the opening of the receiving cavity 10, making it convenient to take out the air-cooled radiator 8.

[0038] Example 3:

[0039] The shell of the air-cooled radiator 8 of the present invention is a square shell that matches the accommodating cavity 10. Its front end is an air outlet, and its rear end is provided with an air inlet. The contact terminal is provided on the plate surface above the air inlet.

[0040] In summary, the power supply device of the present invention improves the mounting structure of the air-cooled radiator, enabling quick insertion and removal of the radiator, facilitating installation and maintenance. The present invention cleverly incorporates a push mechanism that, firstly, stabilizes the contact terminals and, secondly, allows the spring to push a push plate out of a local area of ​​the radiator during removal, facilitating easy removal.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
