Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a welding jig for heat pipe radiators. Background Art

[0002] With the rapid development of the electronics industry, the computing speed of electronic components in computers has increased significantly, and the heat generated has also increased dramatically. How to dissipate the heat of electronic components to ensure their normal operation has always been a problem that the industry must solve. Existing heat pipe radiator soldering jigs have soldering material between the heat pipe and the copper block, and between the heat pipe and the fins. These need to be heated in a tunnel furnace to preheat the welding jig first, then melt the soldering material to connect the heat pipe to the copper block and the heat pipe to the fins. The solder paste takes a long time to melt and the subsequent cooling time is also long, resulting in low production efficiency. Moreover, because the jig is exposed to high temperature for a long time, it will also cause certain damage to the heat pipe in the radiator, such as tube expansion, which also affects the quality of the laptop radiator. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a heat pipe radiator welding jig, which not only avoids the expansion of the heat pipe, thereby ensuring production quality, but also greatly shortens the welding time and energy consumption, and avoids the damage to the heat pipe caused by high temperature and long time, thereby improving the quality of the notebook radiator.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a heat pipe radiator welding jig, wherein the laptop radiator includes a heat pipe, a copper block and a fin, comprising: a non-metallic cover plate, a plurality of non-metallic bases and a plurality of non-metallic carrier plates, wherein the upper surface of the non-metallic carrier plate has a first groove for placing the heat pipe, a first receiving groove for placing the copper block and solder, and a second receiving groove for placing the fin and solder;

[0005] The non-metallic cover is located above the non-metallic carrier. An induction coil is provided between the non-metallic carrier and the non-metallic base. The area where the induction coil is provided includes the area below the first accommodating groove and the second accommodating groove. The surface of the non-metallic cover opposite to the non-metallic carrier has a third groove, and a cooling pipe is installed in the third groove.

[0006] The technical solutions further improved in the above technical solutions are as follows:

[0007] 1. In the above solution, the cooling tube is a cooling copper tube.

[0008] 2. In the above solution, the surface of the non-metallic base facing the non-metallic carrier board has a second groove for placing the induction coil.

[0009] 3. In the above solution, the non-metallic cover plate is a bakelite board, a synthetic stone board or a FR-4 board.

[0010] 4. In the above solution, the non-metallic base is a bakelite board, a synthetic stone board or a FR-4 board.

[0011] 5. In the above solution, the non-metallic carrier board is a bakelite board, a synthetic stone board or a FR-4 board.

[0012] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0013] 1. The present invention provides a heat pipe radiator welding jig comprising a non-metallic cover plate, a plurality of non-metallic bases, and a plurality of non-metallic carrier plates. The non-metallic carrier plate has an upper surface with a first groove, a first receiving groove, and a second receiving groove. The non-metallic cover plate is positioned above the non-metallic carrier plate, and an induction coil is disposed between the non-metallic carrier plate and the non-metallic base. The area where the induction coil is disposed includes the area below the first receiving groove and the second receiving groove. A high-frequency welding machine is connected to the induction coil. The high-frequency induction coil design, which is shaped like a heat pipe, not only heats up multiple radiators simultaneously, improving efficiency, but also significantly shortens welding time and energy consumption due to the direct and rapid transfer of heat to the solder. The even heat distribution also prevents damage to the heat pipe caused by high temperatures and prolonged operation, thereby improving the quality of the laptop radiator.

[0014] 2. The heat pipe radiator welding jig of the present invention realizes that one non-metallic cover plate corresponds to multiple non-metallic bases and non-metallic carrier plates, which reduces costs and greatly improves production efficiency. However, since the non-metallic cover plate will accumulate heat when used repeatedly, a third groove is provided on the surface opposite to the non-metallic carrier plate. A cooling pipe is installed in the third groove, which effectively controls the heat of the cover plate and avoids the expansion of the heat pipe, thereby ensuring production quality.
