[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See also Figures 1 to 6 As shown, the present invention discloses a jig 100 for assembling a plurality of heat sinks. In this embodiment, the plurality of heat sinks are a plate heat sink 3 (ie, a VC heat sink) and a fin heat sink 4 (ie, a FIN heat sink).

[0031] Specifically, the jig 100 includes an upper shell 1 and a lower shell 2 assembled with each other, the lower shell 2 is recessed with a first assembly groove 21 for assembling the plate-shaped radiator 3 and a second assembly groove 22 for assembling the fin-type radiator 4, and the plate-shaped radiator 3 at least partially covers the fin-type radiator 4.

[0032] Preferably, the second assembly groove 22 is recessed on the first assembly groove 21, so that the plate-shaped heat sink 3 completely covers the fin-shaped heat sink 4. In this way, the fin-shaped heat sink 4 can be completely welded on the plate-shaped heat sink 3.

[0033] The first assembly groove 21 and the second assembly groove 22 are both recessed away from the upper shell 1, so that the plate-shaped heat sink 3 and the fin-shaped heat sink 4 are clamped between the upper shell 1 and the lower shell 2. In the height direction of the jig 100, the upper shell 1, the plate-shaped heat sink 3, the fin-shaped heat sink 4 and the lower shell 2 are arranged in sequence.

[0034] The second assembly groove 22 is arranged close to one of the outer wall surfaces of the lower shell 2, and a heating port 23 is formed on the outer wall surface and communicates with the second assembly groove 22, and the fins 41 of the fin-shaped heat sink 4 are at least partially exposed to the heating port 23.

[0035] Soldering flux (not shown) is coated between the plate-shaped heat sink 3 and the fin-shaped heat sink 4, and an external soldering machine heats the fins 41 of the fin-shaped heat sink 4 from the heating port 23, so that the soldering flux is melted and coated between the plate-shaped heat sink 3 and the fin-shaped heat sink 4 through the fins 41. That is, by arranging the heating port 23, the fins 41 exposed to the heating port 23 can be heated, the soldering flux is heated and melted through the heat conduction of the fins 41, and then the plate-shaped heat sink 3 and the fin-shaped heat sink 4 are welded and fixed. Preferably, the soldering flux is tin paste, and the external soldering machine is a high-frequency soldering machine. Experiments have proved that the quality of the finished product obtained by using the high-frequency soldering machine is the best.

[0036] The lower shell 2 is generally rectangular, and in the width direction of the lower shell 2, recesses 241 are respectively recessed on two long sides 24 of the lower shell 2, the shapes of the recesses 241 are adapted to the plate-shaped heat sink 3, and the second assembly groove 22 is arranged in one of the recesses 241.

[0037] In this embodiment, the plate-shaped heat sink 3 is not a complete rectangle, but has some local protrusions. Therefore, the plate-shaped heat sink 3 is accommodated and positioned and guided by the recesses 241.

[0038] The two grooves 241 correspond to each other, and on each side of each groove 241 in the direction of the long side 24 of the lower shell 2, a notch 242 is provided which is recessed in the width direction. The notches 242 on the two long sides 24 correspond to each other. Of course, the two grooves 241 can also be arranged offset, or only one groove can be provided, which can be adjusted according to the actual shape of the plate-shaped heat sink 3.

[0039] The clamping area 251 is formed between the short side 25 of the lower shell 2 and the notch 242, and is used for clamping an external fixing clamp to fix the upper shell 1, the plate-shaped heat sink 3 and the lower shell 2. The finned heat sink 4 is pressed and fixed in the second assembly groove 22 by the plate-shaped heat sink 3 and the lower shell 2. The external fixing clamp is preferably a dovetail clamp or the like which can provide a larger clamping force.

[0040] In the height direction of the lower shell 2, the upper surface of the first assembly groove 21 is higher than the upper surface of the second assembly groove 22, so as to form a shelf 221 between the first assembly groove 21 and the second assembly groove 22.

[0041] The second assembly groove 22 includes a receiving groove 222 which is adapted to the shape of the finned heat sink 4, and a drainage groove 223 which extends from the outer periphery of the receiving groove 222 towards the shelf 221. The receiving groove 222 and the drainage groove 223 communicate with each other and are used to introduce part of the volatiles in the flux into the drainage groove 223.

[0042] In the present embodiment, when more flux is applied, in order to avoid a large-scale adhesion to the plate-shaped heat sink 3 after the flux is melted, which affects the appearance of the finished product and the quality of the plate-shaped heat sink 3. By providing the drainage groove 223, part of the excess flux can be introduced into the drainage groove 223 to protect the plate-shaped heat sink 3. The shelf 221 is provided to provide a buffer space for the excess flux, so as to avoid a large-scale adhesion of the flux directly to the plate-shaped heat sink 3, and on the other hand, part of the excess flux is introduced into the drainage groove 223 through the shelf 221. Therefore, the shelf 221 and the drainage groove 223 also communicate with each other. In addition, by providing the drainage groove 223 and the shelf 221, the volatiles in the flux can also be introduced, so as to avoid a large-scale adhesion of the volatiles in the flux to the plate-shaped heat sink 3.

[0043] In the second assembly groove 22, near the heating port 23, a cantilever arm 224 is arranged in the second assembly groove 22, extending from the supporting platform 221 to the bottom surface of the accommodating groove 222, and arranged near one of the inner walls of the second assembly groove 22, so as to form a limiting space 2241 between the cantilever arm 224 and the inner wall, and the limiting space 2241 limits at least one fin 41 of the finned heat sink 4.

[0044] In the embodiment, only one cantilever arm 224 is arranged, and only one limiting space 2241 is arranged, so as to facilitate the finned heat sink 4 to be taken out later, and in other embodiments, the cantilever arm 224 can be arranged on both sides, and the application is not limited in this respect.

[0045] The cantilever arm 224 is arranged in a stepped manner, so as to adapt to the shape of the fin 41, that is, the stepped shape of the cantilever arm 224 avoids the fin 41 from being incompletely accommodated in the second assembly groove 22.

[0046] In summary, the jig 100 for assembling various heat sinks of the application is arranged with a heating port 23 on the outer wall of the lower shell 2, which is in communication with the second assembly groove 22, so that the fin 41 of the finned heat sink 4 assembled in the second assembly groove 22 is at least partially exposed to the heating port 23, and thus an external welding machine can heat the fin 41 through the heating port 23.

[0047] The above embodiments are only used to illustrate the technical solutions of the application rather than limit the application, and although the application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the application.
