Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for welding equipment, specifically a liquid-cooled circulating heat dissipation structure for welding equipment. Background Technology

[0002] Handheld laser welding machines are a new generation of laser welding equipment, belonging to non-contact welding. No pressure is required during operation. Their main technical features are simple operation, high welding efficiency, aesthetically pleasing weld formation, and wide applicability. During operation, heat dissipation is required inside the machine casing.

[0003] An existing ultrasonic welding equipment heat sink (authorization announcement number: CN216680691U) is convenient to adjust the number of air inlets and easy to use. However, the existing welding equipment usually uses air cooling for heat dissipation inside the chassis. However, while air cooling is being used, the motor inside the fan also generates heat, resulting in poor heat dissipation. In addition, air cooling generates wind noise. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for a liquid-cooled circulating welding equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for a liquid-cooled circulating welding equipment, including a chassis, a door hinged to the front of the chassis, a heat dissipation assembly on the chassis, the heat dissipation assembly including a coolant tank located in the middle of the top surface of the chassis, an inlet pipe connected to one side of the coolant tank, an outlet vertical pipe connected to the top of the coolant tank, a diverter pipe connected to the top of the outlet vertical pipe, upper horizontal pipes connected to both ends of the diverter pipe, the upper horizontal pipes installed on both sides of the top surface of the chassis, multiple spiral flow channels equidistantly connected to the bottom of the upper horizontal pipes, the bottom ends of the spiral flow channels penetrating the bottom of the chassis, and lower horizontal pipes symmetrically arranged on both sides of the bottom surface of the chassis.

[0006] Preferably, the bottom end of the spiral flow channel tube is connected to the top of the corresponding lower horizontal tube, and the spiral flow channel tube is located on both sides inside the chassis. The top and bottom of the chassis are provided with heat dissipation holes.

[0007] Preferably, the two lower horizontal pipes are connected to a connecting pipe at their rear ends. The connecting pipe is installed on the bottom surface of the housing and is arched. A return pipe is connected to the top surface of the connecting pipe.

[0008] Preferably, the top of the return pipe is connected to the coolant tank, the pump body is installed on the outlet vertical pipe, and multiple corrugated heat dissipation fins are equally spaced on both sides of the inner wall of the casing, with the corrugated heat dissipation fins and the spiral flow channel pipes arranged alternately.

[0009] Preferably, the bottom of the chassis is provided with a vibration damping component, which includes support columns fixed at the four corners of the bottom surface of the chassis, a support tube slidably sleeved on the lower part of the support column, the bottom of the support tube being closed, a rolling wheel installed at the bottom end of the support tube, a support spring connected between the support tube and the bottom end of the support column, a damper being provided inside the support spring, and an elastic pad being provided between the coolant tank and the chassis.

[0010] Preferably, a welding assembly is provided on the back of the chassis. The welding assembly includes a connector mounted on the upper part of one side of the back of the chassis, a connecting wire connected to the connector, a welding gun body connected to the outer end of the connecting wire, and a placement block mounted on the chassis below the connector, on which the welding gun body is placed.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The heat dissipation structure of this liquid-cooled circulating welding equipment utilizes heat dissipation and vibration damping components. Coolant from the tank flows through a vertical outlet pipe, a branch pipe, and an upper horizontal pipe into multiple spiral flow channels. Finally, it flows back into the tank via a lower horizontal pipe, a connecting pipe, and a return pipe. This spiral flow channel system cools the corrugated heat dissipation fins, and the liquid-cooled circulation system cools both the corrugated heat dissipation fins and the interior of the chassis, ensuring efficient heat dissipation. Simultaneously, during welding, support springs and dampers effectively reduce vibration, preventing air bubbles or uneven flow of the coolant due to vibration, which could negatively impact heat dissipation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] During the operation of welding equipment, a heat dissipation structure is required. The heat dissipation structure provided by this utility model is specifically designed for liquid cooling circulation heat dissipation inside the chassis 1 to ensure heat dissipation effect. Before using this structure, preparatory work such as inspection is required to ensure its normal use.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a heat dissipation structure for a liquid-cooled circulating welding equipment, including a chassis 1, a door 101 hinged to the front of the chassis 1, a heat dissipation assembly on the chassis 1, the heat dissipation assembly including a coolant tank 2 located in the middle of the top surface of the chassis 1, an inlet pipe connected to one side of the coolant tank 2, an outlet vertical pipe 201 connected to the top of the coolant tank 2, a diversion pipe 202 connected to the top of the outlet vertical pipe 201, upper horizontal pipes 203 connected to both ends of the diversion pipe 202, the upper horizontal pipes 203 installed on both sides of the top surface of the chassis 1, a plurality of spiral flow channel pipes 204 equidistantly connected to the bottom of the upper horizontal pipes 203, the bottom ends of the spiral flow channel pipes 204 penetrating the bottom of the chassis 1, and lower horizontal pipes 205 symmetrically arranged on both sides of the bottom surface of the chassis 1.

[0021] In this embodiment, the bottom end of the spiral flow channel pipe 204 is connected to the top of the corresponding lower horizontal pipe 205. The spiral flow channel pipe 204 is located on both sides inside the chassis 1. The top and bottom of the chassis 1 are provided with heat dissipation holes 102. The back ends of the two lower horizontal pipes 205 are connected to the connecting pipes 206. The connecting pipes 206 are installed on the bottom surface of the chassis 1. The connecting pipes 206 are arched. The top surface of the connecting pipes 206 is connected to the return pipe 207.

[0022] In this embodiment, the top end of the return pipe 207 is connected to the coolant tank 2, and a pump body is installed on the outlet vertical pipe 201. Multiple corrugated heat dissipation fins 3 are equidistantly arranged on both sides of the inner wall of the casing 1. The corrugated heat dissipation fins 3 and the spiral flow channel pipe 204 are spaced apart. It should be noted that after the coolant absorbs heat, this heat is released into the environment through radiators, coolers, etc. to maintain the normal operating temperature of the equipment. This is prior art and will not be described in detail here. The pump body is also prior art.

[0023] In this embodiment, a vibration damping assembly is provided at the bottom of the chassis 1. The vibration damping assembly includes support columns 4 fixed at the four corners of the bottom surface of the chassis 1, a support tube 401 slidably sleeved on the lower part of the support column 4, the bottom of the support tube 401 being closed, a rolling wheel installed at the bottom end of the support tube 401, a support spring 403 connected between the support tube 401 and the bottom end of the support column 4, a damper 402 provided inside the support spring 403, and an elastic pad provided between the coolant tank 2 and the chassis 1. It should be noted that the damper 402, the support spring 403 and the elastic pad are existing technologies.

[0024] In this embodiment, a welding assembly is provided on the back of the chassis 1. The welding assembly includes a connector 5 mounted on the upper part of one side of the back of the chassis 1. A connector 501 is connected to the connector 5, and a welding torch body 502 is connected to the outer end of the connector 501. A placement block 503 mounted on the chassis 1 is provided below the connector 5, and the welding torch body 502 is placed on the placement block 503. Through the arrangement of the heat dissipation assembly and the vibration damping assembly, the coolant in the coolant tank 2 enters multiple spiral flow channels through the outlet vertical pipe 201, the diversion pipe 202, and the upper horizontal pipe 203. Inside the channel pipe 204, the liquid finally flows back to the coolant tank 2 through the lower horizontal pipe 205, the connecting pipe 206, and the return pipe 207. This completes the cooling of the corrugated heat dissipation fins 3 by the spiral flow channel pipe 204. The liquid cooling circulation is used to cool the corrugated heat dissipation fins 3 and the inside of the chassis 1, ensuring heat dissipation. At the same time, during the welding process, the support spring 403 and the damper 402 effectively reduce vibration and prevent the coolant from generating bubbles or flowing unevenly due to vibration, which would affect the heat dissipation effect. The welding components are existing technology, ensuring the welding operation can proceed.

[0025] Working principle: When using this structure for heat dissipation, the corrugated heat dissipation fins 3 absorb heat onto their surface. The coolant in the coolant tank 2 is discharged through the outlet vertical pipe 201, and then enters the upper horizontal pipe 203 through the diversion pipe 202, and then enters the spiral flow channel pipe 204, thereby cooling the corrugated heat dissipation fins 3. The coolant then enters the lower horizontal pipe 205 and the connecting pipe 206, and finally enters the coolant tank 2 through the return pipe 207, completing the circulating cooling and heat dissipation operation.
