Description

Technical Field

[0001] This utility model belongs to the field of welding machine technology, and specifically relates to a heat dissipation structure for a welding machine. Background Technology

[0002] A welding machine is an industrial device that joins metal materials by melting them at high temperatures or applying pressure. Common types include electric arc welding machines, gas shielded welding machines, and laser welding machines. It uses electrical energy to generate heat, melting the base metal and welding wire to form a strong connection. It is widely used in machinery manufacturing, construction, automotive repair, and pipeline engineering, and is characterized by high efficiency, precision, and strong adaptability, making it an indispensable processing tool in modern industry.

[0003] A known authorized patent with application number 201921380865.X discloses a heat dissipation structure for a welding machine, comprising: a housing; a fan installed inside the housing; a first PCB board fixed inside the housing; a heat sink located to one side of the fan, with its bottom fixed to the first PCB board; multiple heat sinks spaced apart, with parallel airflow channels between them; and a guide plate installed on top of the heat sink, forming an airflow channel between the first PCB board, the heat sink, and the guide plate, with the fan located at a corresponding position within the airflow channel. This design improves the utilization rate of the airflow generated by the fan, thereby enhancing the heat dissipation effect.

[0004] However, in implementing the relevant technology, the following problems were found in the above technical solution: Conventionally, the two heat sinks are set in parallel, and the fan is set at one end of the air duct to introduce air. The airflow speed blown out by the fan will gradually slow down. That is to say, the air pressure is greater closer to the inlet end of the air duct and less closer to the outlet end, resulting in different temperatures at the two ends of the heat sink and insufficient airflow.

[0005] Therefore, a heat dissipation structure for a welding machine is proposed to solve the above problems. Utility Model Content

[0006] This utility model proposes a heat dissipation structure for a welding machine, which solves the problem in the conventional technology where two heat dissipation plates are arranged in parallel and a fan is placed at one end of the air duct to introduce air. The airflow speed blown out by the fan gradually slows down, meaning that the air pressure is greater closer to the inlet end of the air duct and less closer to the outlet end. This results in different temperatures at the two ends of the heat dissipation plate, preventing the airflow from moving sufficiently.

[0007] The technical solution of this utility model is as follows: A heat dissipation structure for a welding machine, comprising:

[0008] Welding machine body;

[0009] A heat dissipation assembly is installed inside the welding machine body. The heat dissipation assembly includes two sets of fixed components connected to the welding machine body and a telescopic component installed on the other side of the fixed components.

[0010] A heat sink is provided on the other side of the telescopic component. The telescopic component includes a sealing sleeve and a clamping component for clamping the sealing sleeve. One side of the clamping component is connected to the fixing component and the other side is connected to the heat sink. The inside is filled with heat-conducting fluid. The sealing sleeve is made of flexible silicone material.

[0011] A heat-conducting plate is provided on the rear wall of the heat sink, and an inclined component is provided on one side of the heat sink for moving the two heat sinks at relative angles.

[0012] Preferably, the fixing component includes a fixing plate, the fixing plate having a plurality of fixing bolts inside, the outer wall of the fixing bolts being threadedly connected to the welding machine body;

[0013] The outer wall of the fixing plate is provided with a reserved groove.

[0014] Preferably, the clamping assembly includes a first clamping plate and a second clamping plate, and a clamping bolt is provided inside the reserved slot. The first clamping plate and the clamping bolt are connected by the clamping bolt.

[0015] The second clamping plate is located behind the heat-conducting plate and is connected by the clamping bolts.

[0016] Preferably, the sealing sleeve has connecting edges on both sides, and the first clamping plate and the second clamping plate clamp the connecting edges on both sides of the sealing sleeve for sealing and connecting the sealing sleeve.

[0017] Preferably, the tilting component includes a plurality of connecting posts and connecting blocks disposed on the outer wall of the heat sink, and a first rocker and a second rocker are rotatably connected to the outer walls of two adjacent connecting posts, the first rocker and the second rocker being disposed opposite to each other;

[0018] The ends of the first rocker and the second rocker are rotatably connected to the inner wall of the connecting block.

[0019] Preferably, the heat sink on one side is provided with two sets of tilting components, which are arranged opposite to each other.

[0020] Preferably, the welding machine body has two threaded rods internally rotatably connected, and the threaded rods are threadedly connected to the inner walls of two connecting blocks on the same side.

[0021] Preferably, the welding machine body is equipped with a drive motor, and the output end of the drive motor is fixedly connected to the threaded rod for driving the threaded rod.

[0022] The working principle and beneficial effects of this utility model are as follows:

[0023] 1. By setting the telescopic component, the two heat sinks have a certain tilting ability. By tilting the two heat sinks, the distance between one end of the two heat sinks is reduced. Therefore, after the air enters the air duct, the air pressure at the rear end will not decrease significantly. Even at the rear end of the heat sink, the air can maintain a high contact pressure with the heat sink, so that the heat dissipation performance at the rear end of the heat sink can also be utilized.

[0024] 2. By setting up the tilting component, the first and second rockers can be rotated by moving the two connecting blocks up and down, so that the two heat sinks can be tilted in a controllable manner, making the adjustment of the equipment more automated. Attached Figure Description

[0034] Welding machine body 1;

[0035] A heat dissipation assembly is installed inside the welding machine body 1. The heat dissipation assembly includes two sets of fixed components connected to the welding machine body 1 and a telescopic component installed on the other side of the fixed components.

[0036] The other side of the telescopic component is provided with a heat sink 11. The telescopic component includes a sealing sleeve 7 and a clamping component for clamping the sealing sleeve 7. One side of the clamping component is connected to the fixing component, and the other side is connected to the heat sink 11. The inside is filled with heat-conducting fluid. The sealing sleeve 7 is made of flexible silicone material.

[0037] A heat-conducting plate 9 is provided on the rear wall of the heat sink 11, and an inclined component is provided on one side of the heat sink 11 for moving the two heat sinks 11 in a relatively inclined manner.

[0038] The fixing assembly includes a fixing plate 17, and a plurality of fixing bolts 4 are provided inside the fixing plate 17. The outer wall of the fixing bolts 4 is threadedly connected to the welding machine body 1.

[0039] The outer wall of the fixing plate 17 is provided with a reserved groove 3;

[0040] The clamping assembly includes a first clamping plate 5 and a second clamping plate 6. A clamping bolt 10 is provided inside the reserved groove 3. The first clamping plate 5 and the clamping bolt 10 are connected by the clamping bolt 10.

[0041] The second clamping plate 6 is located behind the heat-conducting plate 9 and is connected by clamping bolts 10;

[0042] The sealing sleeve 7 has connecting edges 8 on both sides. The first clamping plate 5 and the second clamping plate 6 clamp the connecting edges 8 on both sides of the sealing sleeve 7 for sealing and connecting the sealing sleeve 7.

[0043] The tilting assembly includes multiple connecting posts 14 and connecting blocks 15 disposed on the outer wall of the heat sink 11. A first rocker arm 12 and a second rocker arm 13 are rotatably connected to the outer walls of two adjacent connecting posts 14. The first rocker arm 12 and the second rocker arm 13 are disposed opposite to each other.

[0044] The ends of the first rocker arm 12 and the second rocker arm 13 are rotatably connected to the inner wall of the connecting block 15;

[0045] The heat sink 11 on one side is provided with two sets of tilting components, which are arranged opposite to each other.

[0046] The welding machine body 1 has two threaded rods 16 internally rotatingly connected, and the threaded rods 16 are threadedly connected to the inner walls of two connecting blocks 15 on the same side.

[0047] The welding machine body 1 is equipped with a drive motor 2. The output end of the drive motor 2 is fixedly connected to the threaded rod 16 and is used to drive the threaded rod 16.

[0048] The technical solution provided in this embodiment is as follows: During installation, firstly, the second clamping plate 6 is placed behind the heat-conducting plate 9. Then, the connecting edges 8 on both sides of the sealing sleeve 7 are clamped between the second clamping plate 6 and the heat-conducting plate 9. Next, the heat-conducting plate 9 and the second clamping plate 6 are connected by clamping bolts 10, and one side of the connecting edge 8 is clamped. After installation, the first clamping plate 5 is placed inside the sealing sleeve 7. Then, the fixing plate 17 is placed on the other side of the first clamping plate 5. Then, the first clamping plate 5 and the fixing plate 17 are fixed by clamping bolts 10, and the other side of the connecting edge 8 is clamped. After the connection is completed, heat-conducting liquid can be injected into the sealing sleeve 7. Then, the other side of the equipment is installed in the same way. After installation, the welding machine body 1 and the heat dissipation assembly are fixed by fixing bolts 4. Then it can be used. If the temperature difference between the two ends of the heat sink 11 is large during use, the drive motor 2 can be driven. The drive motor 2 drives the threaded rod 16 to rotate. Through the rotation of the threaded rod 16, the connecting block 15 moves up and down. When the connecting block 15 moves upward, the angle between the first rocker arm 12 and the second rocker arm 13 on the lower side decreases, and the two connecting posts 14 move closer. The angle between the first rocker arm 12 and the second rocker arm 13 on the upper side increases, pushing the top of the heat sink 11 to both sides. The upper and lower sides move simultaneously to ensure that the total volume inside the sealing sleeve 7 remains unchanged and the shape changes with the angle of the heat sink 11. This avoids air bubbles and air in the heat-conducting liquid inside the sealing sleeve 7. After the angle is adjusted, the spacing between the heat sinks 11 at the upper and lower ends is different, so the air duct between the two heat sinks has a gradually narrowing trend. Therefore, after the air enters the air duct, the air pressure will not decrease significantly, increasing the heat dissipation efficiency of the equipment.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
