[0022] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments in the following description are only as examples, and those skilled in the art can think of other obvious modifications.
[0023] Referring to Figures 1-5 As shown in the figure, a heat dissipation module welding jig comprises a jig part for fixing and supporting the heat dissipation module and a layered clamping part arranged in the jig part;
[0024] The jig part is mainly composed of an aluminum base 1 and two side cover plates 12, both of which are detachably arranged on the two sides of the aluminum base 1 by bolts, and the top of the aluminum base 1 is open;
[0025] The layered clamping part comprises positioning bottom plates one and two arranged on the inner side of the aluminum base 1, with the positioning bottom plate two being above the positioning bottom plate one, and the outer periphery of the positioning bottom plate two being provided with a press-fitting assembly;
[0026] Through the arrangement of the layered clamping part, the mutual cooperation of the positioning bottom plates one and two can effectively replace the use of the existing C-shaped clamp, which not only facilitates manual fixing of the multiple heat pipes, but also reduces the overall height of the jig, making it convenient for the product to pass through the reflow soldering furnace.
[0027] Specifically, referring to Figure 5 As shown in the figure, it is worth noting that the positioning bottom plate one comprises a heat spreading plate 2 attached to the inner wall of the bottom end of the aluminum base 1 and a plurality of positioning strips one 3 fixed to the top surface of the heat spreading plate 2 at equal intervals;
[0028] The positioning bottom plate two comprises a press-fitting plate 5 located in the opening of the aluminum base 1 and a plurality of positioning strips two 6 fixed to the top surface of the press-fitting plate 5 at equal intervals;
[0029] The existing heat dissipation module usually has three groups of heat dissipation fins arranged side by side, among which the heat dissipation fins on both sides share multiple heat pipes one 4, and the heat dissipation fin in the middle is internally separately configured with multiple heat pipes two 7;
[0030] Therefore, when assembling the heat dissipation module, the multiple heat pipes one 4 are sequentially clamped into the gaps between the multiple positioning strips one 3 on the heat spreading plate 2, and then the heat pipes one 4 are positioned by gap cooperation, so that when the heat pipes one 4 are manually placed on both sides of the top of the aluminum base 1, the heat pipes one 4 will not move under force;
[0031] After the heat dissipation fins on both sides are placed, the press-fitting plate 5 is placed in the middle of the multiple heat pipes one 4, and then the multiple heat pipes two 7 are sequentially clamped into the gaps between the multiple positioning strips two 6 on the press-fitting plate 5, and the heat pipes two 7 are positioned by gap cooperation, so that when the heat pipes two 7 are placed in the middle heat dissipation fin, the heat pipes two 7 will not move under force.
[0032] In addition, referring to Figures 2-4As shown, it is worth mentioning that the pressing assembly includes two symmetrical pressing aluminum strips 10 distributed on the left and right sides of the top surface of the pressing plate 5, and the two ends of the pressing aluminum strip 10 are detachably connected with the aluminum base 1 through bolts.
[0033] Through the setting of the pressing aluminum strip 10, after the pressing plate 5 is placed in the middle of the plurality of heat pipes one 4, two pressing aluminum strips 10 are placed on the top surface of the pressing plate 5 from both sides, and the pressing aluminum strips 10 are locked by bolts. Thus, the two pressing aluminum strips 10 cooperate with each other to press the pressing plate 5 from top to bottom, and simultaneously press the plurality of heat pipes one 4 in the middle, thereby further realizing the fixing property of the plurality of heat pipes one 4.
[0034] Further, referring to Figure 4 As shown, it is worth mentioning that the pressing assembly further includes two symmetrical positioning aluminum blocks 11 distributed on the front and rear sides of the pressing plate 5, and the positioning aluminum block 11 is detachably connected with the aluminum base 1 through bolts.
[0035] Through the setting of the positioning aluminum block 11, after the pressing plate 5 is placed, the positioning aluminum block 11 can still be placed on the front and rear sides of the pressing plate 5 by artificial. Thus, the two positioning aluminum blocks 11 cooperate with each other to clamp the pressing plate 5 front and rear, thereby ensuring the stable strength of the plurality of heat pipes one 4 on the pressing plate 5.
[0036] Further, referring to Figure 2 As shown, it is worth mentioning that the upper surface of the positioning bottom plate two is provided with fin positioning plates 9 on the left and right sides, and the two fin positioning plates 9 are provided with a pipe pressing plate 8 therebetween.
[0037] Through the setting of the fin positioning plate 9, after the middle heat dissipation fin is placed on the pressing plate 5, the fin positioning plate 9 is inserted into the gap between the middle heat dissipation fin and the heat dissipation fin on both sides, and then the fin positioning plate 9 can effectively press and position the positions of the three groups of fins;
[0038] And through the setting of the pipe pressing plate 8, in the production and manufacture of the middle heat dissipation fin, a gap insertion cavity which is matched with the pipe pressing plate 8 is arranged in the middle. Thus, after the middle heat dissipation fin is placed on the pressing plate 5, the pipe pressing plate 8 is inserted into the gap insertion cavity, and the bottom end of the pipe pressing plate 8 can have the same effect as the pressing plate 5 to press the plurality of heat pipes two 7 from top to bottom, thereby realizing the locking effect of the pipe pressing plate 8.
[0039] Further, referring to Figure 3 and Figure 4 As shown, it is worth mentioning that the inner walls on the front and rear sides of the aluminum base 1 are symmetrically provided with support grooves 14, and the positioning aluminum block 11 is in a stepped shape.
[0040] Through the setting of the support grooves 14 and the positioning aluminum blocks 11, when the heat dissipation fins are placed into the aluminum base 1 and the pressing plate 5, the corners of the heat dissipation fins can enter the support grooves 14 or the gaps of the positioning aluminum blocks 11, thereby assisting in supporting the heat dissipation fins, so that the heat dissipation fins can have a gap with the inner wall of the bottom end of the aluminum base 1 or the pressing plate 5, so as to avoid direct contact and crush the heat pipe 4 or the heat pipe 7.
[0041] Further, referring to Figure 1 It is worth mentioning that the jig part further comprises a top cover plate 13, and the top cover plate 13 is detachably connected between the top ends of the two side cover plates 12 by bolts.
[0042] Through the setting of the top cover plate 13, after the heat dissipation module composed of three groups of heat dissipation fins is assembled on the aluminum base 1, the top cover plate 13 is assembled between the two side cover plates 12, and then the three groups of heat dissipation fins are pressed by the top cover plate 13, so as to effectively stabilize and strengthen the heat dissipation fins.
