Description

Technical Field

[0001] This application relates to the technical field of cooling devices, and particularly to a cooling device for a protective cover used in the welding of adapter plates. Background Art

[0002] An adapter plate is a small metal sheet or electronic component used to connect or support different components and fittings, and has important applications in the lithium battery production industry; when continuous welding of adapter plates is carried out, in order to ensure safety during the production process, a protective cover is usually used for protection to ensure the safety of workers. However, during the welding process, the protective cover is affected by the welding laser, and its own temperature continues to rise. Due to the poor heat dissipation performance of the protective cover, the relatively high temperature carried by the protective cover will affect the welding effect of the adapter plate, so it needs to be improved. Utility Model Content

[0003] In order to improve the heat dissipation and cooling performance of the protective cover and improve the welding effect on the adapter plate, this application provides a cooling device for a protective cover used in the welding of adapter plates.

[0004] A cooling device for a protective cover used in the welding of adapter plates provided by this application adopts the following technical solutions:

[0005] A cooling device for a protective cover used in the welding of adapter plates includes a protective cover body. The protective cover body includes a top plate and a cover body. An installation cavity is formed in the top wall of the cover body. The top plate covers the upper part of the installation cavity. A heat exchange tube is arranged in the installation cavity. The heat exchange tube is arranged in a meandering shape. Water inlets and water outlets are formed in the side wall of the cover body. Both the water inlets and water outlets are communicated with the installation cavity, and diversion tubes are arranged at both the water inlets and water outlets. The two diversion tubes are respectively communicated with the input end and the output end of the heat exchange tube.

[0006] By adopting the above technical solutions, during the use of the protective cover body, cooling water is introduced into the heat exchange tube through the diversion tube at the water inlet. The hot air in the installation cavity will exchange heat with the cooling water through the outer wall of the heat exchange tube. The temperature of the cooling water rises and it leaves from the water outlet, so as to effectively cool the protective cover body, reduce the influence on the welding of the adapter plate caused by the too high temperature of the protective cover body, and further improve the welding effect of the adapter plate.

[0007] Optionally, one end of the diversion tube is inserted into the installation cavity, and a stepped portion is arranged at the end of the diversion tube extending into the installation cavity. The outer diameter of the stepped portion is the same as the inner diameter of the heat exchange tube, and the stepped portion is inserted into the heat exchange tube.

[0008] By adopting the above technical solutions, setting the stepped portion can effectively improve the connection tightness between the diversion tube and the heat exchange tube, so as to improve the sealing performance between the diversion tube and the heat exchange tube.

[0009] Optionally, a sealing shaft sleeve is threadedly connected to the peripheral wall of the heat exchange tube close to the diversion tube. The outer diameter of the diversion tube is the same as that of the heat exchange tube. A threaded section is provided on the peripheral wall of one end of the diversion tube extending into the placement cavity. After the sealing shaft sleeve rotates, it is threadedly connected to the peripheral wall of the diversion tube.

[0010] By adopting the above technical solution, the setting of the sealing shaft sleeve can seal the connection between the diversion tube and the heat exchange tube, so as to reduce the problem that the cooling water in the diversion tube and the heat exchange tube overflows from the gap between the two, thereby effectively improving the overall sealing performance of the device.

[0011] Optionally, a fastener is provided at the end of the sealing shaft sleeve, and the fastener passes through the sealing shaft sleeve and is connected to the inner wall of the placement cavity.

[0012] By adopting the above technical solution, the setting of the fastener can effectively fix the sealing shaft sleeve to prevent the sealing shaft sleeve from loosening from the diversion tube and improve the overall stability.

[0013] Optionally, a fixed flange is provided on the peripheral wall of the diversion tube outside the cover body, and the fixed flange is connected to the outer wall of the cover body.

[0014] By adopting the above technical solution, the setting of the fixed flange can fix the diversion tube to improve the stability between the diversion tube, the cover body and the heat exchange tube.

[0015] Optionally, a flow cavity is provided on the bottom wall of the cover body. The flow cavity is communicated with the placement cavity. Two protective layers are provided in the flow cavity. The two protective layers are arranged along the height direction of the cover body. Each protective layer includes a plurality of blocking pieces, and the blocking pieces of the two protective layers are arranged in a staggered manner.

[0016] By adopting the above technical solution, opening the flow cavity can facilitate the heat generated at the welding joint to enter the placement cavity, so as to exchange heat with the heat exchange tube, and can effectively prevent the problem that the heat accumulates at the bottom of the protective cover body and cannot achieve effective heat exchange and cooling. The setting of the two protective layers can effectively isolate the placement cavity and the welding joint, thereby preventing the sparks generated during the welding process from splashing into the placement cavity and damaging the heat exchange tube.

[0017] Optionally, a plurality of bearing frames for preventing the heat exchange tube are provided on the inner wall of the placement cavity.

[0018] By adopting the above technical solution, the setting of the bearing frame can maintain the stability of the installation of the heat exchange tube to prevent the heat exchange tube from falling off and improve the safety of the protective cover body during use.

[0019] Optionally, a plurality of heat dissipation grooves are provided through the top plate in the thickness direction.

[0020] By adopting the above technical solution, heat dissipation grooves are provided to discharge heat from the placement cavity, thereby effectively reducing the temperature in the placement cavity. At the same time, the heat exchange tube can be effectively cooled, further improving the heat dissipation performance of the protection cover body.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. During the use of the protection cover body, cooling water is introduced into the heat exchange tube through the diversion tube at the water inlet. The hot air in the placement cavity will exchange heat with the cooling water through the outer wall of the heat exchange tube. The temperature of the cooling water rises and it leaves from the water outlet, thereby effectively cooling the protection cover body to reduce the impact of excessive temperature of the protection cover body on the welding of the adapter piece, and further improving the welding effect of the adapter piece;

[0023] 2. Providing a flow cavity facilitates the heat generated at the welding point to enter the placement cavity, so as to exchange heat with the heat exchange tube, effectively preventing the problem that heat accumulates at the bottom of the protection cover body and cannot achieve effective heat exchange and cooling. The setting of the two-layer protective layer can effectively isolate the placement cavity and the welding point, thereby preventing the problem that the sparks generated during the welding process splash into the placement cavity and damage the heat exchange tube.
