In order to better connect the heat dissipation component and the heat transfer component, the heat dissipation component and the heat transfer component are usually connected by soldering. After soldering the heat dissipation component and the heat transfer component, rosin is likely to remain on the surfaces of the heat transfer component and the heat dissipation component, resulting in the paint on the surfaces of the heat transfer component and the heat dissipation component peeling off, thereby affecting the service life of the heat transfer component and the heat dissipation component.

[0051] The present invention provides a welding jig.

[0052] In an embodiment of the present invention, as Figures 1 to 10 shown, the welding jig includes:

[0053] A jig base 1, the jig base 1 having a placement position 111, a mounting groove 112, and an air inlet hole 113; the placement position 111 is configured to place the heat transfer member 4, and the mounting groove 112 is configured to place the heat dissipation member 3;

[0054] The mounting groove 112 has a longitudinal wall 1121 adjacent to the placement position 111, and the longitudinal wall 1121 is configured to enclose a gas passing gap 114 with the heat dissipation member 3, and the gas passing gap 114 communicates with the air inlet hole 113;

[0055] The mounting groove 112 further has a first transverse wall 1123, the first transverse wall 1123 is located at the first end of the mounting groove 112, and the first transverse wall 1123 is configured to enclose a first exhaust gap 115 with the heat dissipation member 3, and the first exhaust gap 115 communicates the external space and the gas passing gap 114; and / or,

[0056] The mounting groove 112 further has a second transverse wall 1124, the second transverse wall 1124 is located at the second end of the mounting groove 112, and the second transverse wall 1124 is configured to enclose a second exhaust gap 116 with the heat dissipation member 3, and the second exhaust gap 116 communicates the external space and the gas passing gap 114.

[0057] The welding jig is used for assembling the heat dissipation member 3 and the heat transfer member 4. The heat dissipation member 3 is a heat dissipation fin for heat dissipation. The heat transfer member 4 is a heat pipe for transferring heat. The assembly jig positions the heat dissipation member 3 and the heat transfer member 4 to facilitate welding the heat dissipation member 3 and the heat transfer member 4. The heat dissipation member 3 can be directly welded to the heat transfer member 4 or indirectly welded to the heat transfer member 4. When directly or indirectly welding the heat dissipation member 3 and the heat transfer member 4, since rosin is placed in the solder paste, rosin is likely to generate gas during the welding process. If the vaporized rosin is not processed during the welding process, the vaporized rosin is likely to adhere to the heat dissipation member 3 or the heat transfer member 4 nearby, affecting the adhesion of the paint to the heat transfer member 4 or the heat dissipation member 3 during painting.

[0058] The fixture base 1 is provided with a placement position 111, a mounting groove 112, and an air inlet hole 113. The placement position 111 can be in the shape of a groove, a notch, or a space surrounded by protrusions, etc. The placement position 111 is used to place the heat transfer member 4. The mounting groove 112 is used to place the heat dissipation member 3. One side of the mounting groove 112 is communicated with the placement position 111, so that the heat dissipation member 3 and the heat transfer member 4 can be directly or spaced welded through the communicated position. The side wall of the mounting groove 112 adjacent to the placement position 111 has a longitudinal wall 1121. When the heat dissipation member 3 is arranged in the mounting groove 112, there is a gap between the heat dissipation member 3 and the longitudinal wall 1121, so that an air passing gap 114 is formed between the longitudinal wall 1121 and the heat dissipation member 3. There are various ways to arrange the gap between the heat dissipation member 3 and the longitudinal wall 1121. For example, a boss is arranged on the longitudinal wall 1121, and the boss abuts against the heat dissipation member 3, so that there is a gap between the heat dissipation member 3 and the longitudinal wall 1121. Another example is that the longitudinal wall 1121 is inclined, and an air passing gap 114 is formed between the inclined longitudinal wall 1121 and the heat dissipation member 3. Another example is that a groove is opened on the longitudinal wall 1121, and an air passing gap 114 is formed between the groove and the heat dissipation member 3. Another example is that after the heat dissipation member 3 is arranged in the mounting groove 112, the heat dissipation member 3 is arranged away from the longitudinal wall 1121, so that an air passing gap 114 is formed between the heat dissipation member 3 and the longitudinal wall 1121, etc. After the heat dissipation member 3 and the longitudinal wall 1121 form the air passing gap 114, one side of the air passing gap 114 is communicated with the air inlet hole 113, so that the air flow 200 in the air inlet hole enters the air passing gap 114 through the air passing hole 113 to form an air passing gap air flow 210.

[0059] The mounting groove 112 also has a first transverse wall 1123. The first transverse groove wall is located at the first end of the mounting groove 112. When the heat dissipation member 3 is arranged in the mounting groove 112, there is a gap between the first transverse wall 1123 and the heat dissipation member 3, so that a first exhaust gap 115 is formed between the first transverse wall 1123 and the heat dissipation member 3. There are various ways to arrange the gap between the first transverse wall 1123 and the heat dissipation member 3, such as the first transverse wall 1123 and the heat dissipation member 3 are inclined, and a boss is arranged between the first transverse wall 1123 and the heat dissipation member 3, etc. The first exhaust gap 115 is respectively communicated with the external space and the air passing gap 114, so that when the heat dissipation member 3 and the heat transfer member 4 are welded, the gas formed by the rosin in the solder paste is dissipated to the air passing gap 114. After that, the air passing gap air flow 210 takes away the rosin gas 300 in the air passing gap 114 and enters the first exhaust gap 115 to form a first exhaust gap air flow 220. The first exhaust gap air flow 220 is discharged to the external space through the first exhaust gap 115. It avoids the gas formed by the rosin from adhering to the heat dissipation member 3 or the heat transfer member 4, thus affecting the adhesion of the paint to the heat dissipation member 3 or the heat transfer member 4 when painting. And / or,

[0060] The mounting groove 112 further has a second transverse wall 1124. The second transverse groove wall is located at the second end of the mounting groove 112. When the heat dissipation member 3 is disposed in the mounting groove 112, there is a gap between the second transverse wall 1124 and the heat dissipation member 3, so that a second exhaust gap 116 is formed between the second transverse wall 1124 and the heat dissipation member 3. There are various ways to space the second transverse wall 1124 and the heat dissipation member 3, such as the second transverse wall 1124 and the heat dissipation member 3 being inclined, or a boss being provided between the second transverse wall 1124 and the heat dissipation member 3. The second exhaust gap 116 is used to exhaust the gas in the gas passing gap 114. So that when the heat dissipation member 3 and the heat transfer member 4 are welded, after the gas formed by the rosin in the solder paste is dissipated into the gas passing gap 114, the gas passing gap air flow 210 takes away the rosin gas 300 in the gas passing gap 114 and enters the second exhaust gap 116 to form a second exhaust gap air flow 230. The second exhaust gap air flow 230 is discharged into the external space through the second exhaust gap 116. This avoids the gas formed by the rosin from adhering to the heat dissipation member 3 or the heat transfer member 4, thus affecting the adhesion of the paint to the heat dissipation member 3 or the heat transfer member 4 during painting.

[0061] The present invention relates to a welding jig for a city. By providing a placement position 111, a mounting groove 112 and an air inlet hole 113 on a jig base 1. The placement position 111 is used to place the heat transfer member 4, and the mounting groove 112 is used to place the heat dissipation member 3. The mounting groove 112 has a longitudinal wall 1121 adjacent to the placement position 111. A gas passing gap 114 is formed by spacing between the longitudinal wall 1121 and the heat dissipation member 3. The gas passing gap 114 communicates with the air inlet hole 113. So that the air inlet hole air flow 200 passing through the air inlet hole can enter the gas passing gap 114, and the air inlet hole air flow 200 forms a gas passing gap air flow 210 after entering the gas passing gap 114.

[0062] The first end of the mounting groove 112 has a first transverse wall 1123 and / or the second end of the mounting groove 112 has a second transverse wall 1124. A first exhaust gap 115 is formed between the first transverse wall 1123 and the heat transfer member 4 and / or a second exhaust gap 116 is formed between the second transverse wall 1124 and the heat transfer member 4. The first exhaust gap 115 is connected to the external space through the air passage gap 114 and / or the second exhaust gap 116 is connected to the external space through the air passage gap 114. The air passage gap air flow 210 can enter the first exhaust gap 115 to form a first exhaust gap air flow 220 and / or the air passage gap air flow 210 can enter the second exhaust gap 116 to form a second exhaust gap air flow 230. Thus, when the heat dissipation member 3 is welded to the heat transfer member 4, the gas formed by the rosin in the solder paste is dissipated to the air passage gap 114. The air passage gap air flow 210 blows the rosin gas to the first exhaust gap 115 and then blows it out of the external space through the first exhaust gap air flow 220, and / or the air passage gap air flow 210 blows the rosin gas to the second exhaust gap 116 and then blows it out of the external space through the second exhaust gap air flow 230. This prevents the rosin from adhering to the heat dissipation member 3 or the heat transfer member 4, thereby extending the service life of the heat dissipation member 3 or the heat transfer member 4.

[0063] In some examples, such as Figure 3 and Figure 10 as shown, the mounting groove 112 has a contact wall facing the longitudinal wall 1121;

[0064] The bottom of the mounting groove 112 has a guiding inclined surface 1122 which is inclined towards the contact wall. The guiding inclined surface 1122 is configured to contact the heat dissipation member 3 so that the heat dissipation member 3 is inclined towards the contact wall to form the air passage gap 114; or,

[0065] The longitudinal wall 1121 is inclined towards the top of the contact wall so that the air passage gap 114 is formed between the heat dissipation member 3 and the longitudinal wall 1121.

[0066] The mounting groove 112 has a contact wall facing the longitudinal wall 1121. The contact wall is used to contact the heat dissipation member 3 to limit the movement of the heat dissipation member 3 towards the contact wall. The bottom of the mounting groove 112 has a guiding inclined surface 1122 which is inclined towards the contact wall to facilitate the inclined surface to guide the heat dissipation member 3 towards the contact wall, so that the air passage gap 114 is formed between the heat dissipation member 3 and the longitudinal wall 1121. Or,

[0067] The installation groove 112 has an abutting wall facing the longitudinal wall 1121. The abutting wall is used to abut against the heat dissipation member 3 to limit the movement of the heat dissipation member 3 in the direction of the abutting wall. The bottom of the installation groove 112 has a guiding inclined surface 1122, and the guiding inclined surface 1122 is inclined towards the abutting wall. After the heat dissipation member 3 is arranged in the installation groove 112, the guiding inclined surface 1122 is used to abut against the heat dissipation member 3, so that the heat dissipation member 3 is inclined towards the abutting wall, and there is a gap between the heat dissipation member 3 and the longitudinal wall 1121, thereby forming a gas passing gap 114.

[0068] It should be noted that the air inlet hole 113 is preferably arranged adjacent to the longitudinal wall 1121. When the heat dissipation member 3 is installed in the installation groove 112, the heat dissipation member 3 can be reduced from blocking the air inlet hole 113, thereby avoiding the blockage of the air flow 22 in the air inlet hole. In addition, the air flow 22 entering the gas passing gap can be increased.

[0069] In some examples, such as Figures 4 to 10 shown, the heat dissipation member 3 has a third exhaust gap;

[0070] The jig base 1 has an exhaust notch 117 communicating with the external space. The exhaust notch 117 is located on the side of the installation groove 112 away from the placement position 111. The exhaust notch 117 communicates with the installation groove 112. The exhaust notch 117 is configured to communicate with the third exhaust gap, and the gas passing gap 114 is configured to communicate with the third exhaust gap; and / or,

[0071] The number of the air inlet holes 113 is multiple, and the multiple air inlet holes 113 are at least arranged in a row of holes, and the row of holes extends along the length direction of the installation groove 112.

[0072] By providing an exhaust notch 117 communicating with the installation cavity and the external space on the side of the jig base 1 away from the placement position 111, at the same time, connecting the third exhaust gap 32 of the heat dissipation member 3 through the gas passing gap 114 and the exhaust notch 117, so that the gas passing gap air flow 210 in the gas passing gap 114 blows the rosin gas 300 to the third exhaust gap 32. After passing through the third exhaust gap 32, the gas passing gap air flow 210 forms a third exhaust gap air flow 260. The third exhaust gap air flow 260 enters the exhaust notch 117 after passing through the third exhaust gap 32 and is dissipated to the external space through the exhaust notch. The efficiency of discharging the gas to the external space is further improved. In order to have more air flow entering the gas passing gap 114, the number of the air inlet holes 113 is multiple, and the multiple air inlet holes 113 are at least arranged in a row of holes (at least arranged in a row of holes means at least one row of holes), and the row of holes extends along the length direction of the installation groove 112. When there are multiple rows of holes, the multiple rows of holes are arranged along the width direction of the installation groove 112. Setting the number of the air inlet holes 113 to be multiple is beneficial to increasing the number of air flows entering the gas passing gap 114, thereby improving the efficiency of discharging the gas in the gas passing gap 114.

[0073] In some examples, such as Figure 3 、 Figure 7 and Figure 8 shown, the fixture base 1 has a first exhaust groove 118 communicating with the external space. The first exhaust groove 118 is adjacent to the first end of the installation groove 112 and the placement position 111. The first exhaust groove 118 communicates with the air passing gap 114. The air outlet of the first exhaust groove 118 is configured to blow away the gas generated by welding the heat dissipation member 3 and the heat transfer member 4; and / or,

[0074] The fixture base 1 has a second exhaust groove 119 communicating with the external space. The second exhaust groove 119 is adjacent to the second end of the installation groove 112 and the placement position 111. The second exhaust groove 119 communicates with the air passing gap 114. The air outlet of the second exhaust groove 119 is configured to blow away the gas generated by welding the heat dissipation member 3 and the heat transfer member 4.

[0075] To facilitate blowing away the gas at the edge of the placement position 111 of the heat transfer member 4 and the gas at the edge of the heat dissipation member 3 when welding the heat transfer member 4 and the heat dissipation member 3, the fixture base 1 is further provided with a first exhaust groove 118 and / or a second exhaust groove 119. The first exhaust groove 118 is arranged adjacent to the first end of the installation groove 112 and the placement position 111 at the position adjacent to the first end. The first exhaust groove 118 is arranged to communicate with the installation groove 112 from the first end. At the same time, the first exhaust groove 118 also communicates with the air passing gap 114, so that when the air passing gap air flow 210 blows away the rosin gas 300, part of the air passing gap air flow 210 can enter the first exhaust groove 118. After the air passing gap air flow 210 enters the first exhaust groove 118, a first exhaust groove air flow 240 is formed. Since the first exhaust groove 118 is adjacent to the first end of the installation groove 112 and the edge of the placement position 111, the first exhaust groove air flow 240 can blow away the rosin gas 300 near the first exhaust groove 118 after passing through the first exhaust groove 118. The second exhaust groove 119 is arranged adjacent to the second end of the installation groove 112 and the placement position 111 at the position adjacent to the second end. The second exhaust groove 119 is arranged to communicate with the installation groove 112 from the second end. At the same time, the second exhaust groove 119 can also discharge the rosin gas in the air passing gap 114. In addition, the second exhaust groove 119 communicates with the air passing gap 114, so that when the air passing gap air flow 210 blows away the rosin gas 300, part of the air passing gap air flow 210 can enter the second exhaust groove 119. After the air passing gap air flow 210 enters the second exhaust groove 119, a second exhaust groove air flow 250 is formed. Since the second exhaust groove 119 is adjacent to the second end of the installation groove 112 and the edge of the placement position 111, the second exhaust groove air flow 250 can blow away the rosin gas 300 near the second exhaust groove 119 after passing through the second exhaust groove 119.

[0076] In some examples, such as Figures 3 to 5 shown, a copper plate 5 is provided corresponding to the heat dissipation member 3 and the heat transfer member 4, and the copper plate 5 has a first welding portion and a second welding portion;

[0077] The jig base 1 further has a first welding area and a second welding area. The first welding area is configured to place the first welding portion, and the second welding area is configured to place the second welding portion;

[0078] The jig base 1 further has intake slots 120, and there are a plurality of the intake slots 120, and the intake slots 120 are spaced apart from each other;

[0079] The intake slot 120 communicates with the first welding area, and the first welding area and the intake slot 120 form a second air-dissipating channel; and / or,

[0080] The intake slot 120 communicates with the second welding area, and the second welding area and the intake slot 120 form a third air-dissipating channel.

[0081] For better heat transfer, the heat dissipation member 3 and the heat transfer member 4 are welded together through the copper plate 5. In this way, there can be a larger contact surface between the heat dissipation member 3 and the heat transfer member 4, so that the heat of the heat transfer member 4 can be better transferred to the heat dissipation member 3 for heat dissipation. The copper plate 5 has a first welding portion and a second welding portion. The first welding portion is used for welding with the heat transfer member 4, and the second welding portion is used for welding with the heat dissipation member 3. The jig base 1 further has a first welding area for placing the first welding portion and a second welding area for placing the second welding portion. The first welding area communicates with the placement position 111, so that the first welding portion can be welded with the heat transfer member 4 through the position where the first welding area communicates with the placement position 111. The second welding area communicates with the installation groove 112, so that the second welding portion can be welded with the heat dissipation member 3 through the position where the second welding area communicates with the installation groove 112.

[0082] In order to further reduce the adhesion of rosin to the heat transfer member 4 or the heat dissipation member 3 during the welding process, the jig base 1 further has intake slots 120. The number of the intake slots 120 is multiple. The multiple intake slots 120 are located on one side of the placement position 111, or can be located on both sides of the placement position 111, etc. Each intake slot 120 is arranged adjacent to the placement position 111 and communicates with the first welding area and / or the second welding area. The intake slot allows the intake slot air flow to pass through and blows away the rosin air flow 300 located in the first welding area and / or the second welding area. So as to facilitate the air flow passing through the intake slot 120 to blow away the gas generated by the rosin when the copper plate 5 is welded with the heat transfer member 4 and / or the heat dissipation member 3, so that the gas generated by the rosin cannot adhere to the copper plate 5, the heat transfer member 4 or the heat dissipation member 3. Thereby improving the service life of the copper plate 5, the heat transfer member 4 and the heat dissipation.

[0083] In some examples, such as Figure 1 、Figure 2 and Figure 4 As shown in Figure 4 , the fixture base 1 includes a fixture body 11 and a support portion 12.

The baffle plate 2 is detachably connected to the support portion 12, and a gas blocking gap 22 is formed at an interval between the baffle plate 2 and the fixture body 11.

[0084] The gas blocking gap 22 communicates with the first welding area, so that the airflow passing through the first welding area forms a first swirling airflow in the gas blocking gap 22; and / or,

[0085] The gas blocking gap 22 communicates with the second welding area, so that the airflow passing through the second welding area forms a second swirling airflow in the gas blocking gap 22.

[0086] The baffle plate 2 has an air outlet groove 21 penetrating through the baffle plate 2. There is at least one air outlet groove 21, and the air outlet groove 21 is connected to the gas blocking gap 22.

[0087] In order to further improve the dissipation of the rosin gas generated by the welding heat dissipation part 3 and the heat transfer part 4, the welding fixture further includes a baffle plate 2. The baffle plate 2 is used to block the airflow passing through the first welding area and / or the airflow passing through the second welding area, so that the airflow passing through the first welding area forms a swirling airflow 400, thereby taking away the rosin gas 300 near the first welding area, and the airflow passing through the second welding area forms a swirling airflow 400, thereby taking away the rosin gas 300 near the second welding area, so as to improve the gas dissipation effect of the first welding area and the second welding area.

[0088] In order to reduce the swirling airflow from contacting a larger area of the heat dissipation part 3 or the heat transfer part 4, the baffle plate 2 is provided with air outlet grooves 21 penetrating through the baffle plate 2. There are multiple air outlet grooves 21, and the air outlet grooves 21 are spaced apart from each other and communicate with the gas blocking gap 22, so as to facilitate the discharge of the gas in the gas blocking gap 22 through each air outlet groove 21.
