Description

Technical Field

[0001] This utility model belongs to the field of flow channel plate assembly technology, and in particular relates to a novel welding structure for preventing welding overflow in water-side flow channel plates. Background Technology

[0002] With the increasing integration of thermal management systems in new energy vehicles, the demand for integrated thermal management module assemblies has emerged. These assemblies physically integrate and encapsulate the dispersed components of a new energy vehicle's thermal management system into a single module, thereby saving space, improving assemblability, reducing weight, and lowering overall vehicle costs. Based on the benefits these integrated thermal management module assemblies bring to automobiles, they are gradually becoming standard equipment. The emergence of these assemblies has also spurred changes in the assembly methods and processes of other components, leading to the configuration of integrated thermal management modules. Before being integrated into a modular assembly, automotive thermal management systems used circular hoses to control the flow of coolant. However, with the integrated modular assembly, a single plastic flow channel plate replaces and integrates all the original hoses, thus controlling the coolant flow. Due to manufacturing limitations, the plastic flow channel plate is formed by welding the upper and lower flow channels together to create a closed channel. Therefore, for the flow channel plate, cleanliness and welding quality are crucial, including airtightness, weld strength, and control of weld spatter. However, it still has the following drawbacks in practical use:

[0003] In existing technical solutions, the welding structures of the upper and lower flow channels are all achieved by a boss collision structure. The specific process is to clamp the upper and lower flow channels onto a tooling and heat the welding boss structures of each to melt them. Then, the upper and lower flow channels are collided and squeezed by the tooling through quantitative movement, so that the molten bosses are squeezed and fused together, thereby achieving effective welding. However, during welding, the flow channel is prone to generating welding flanges on the inner side, which affects the flow stability after the flow inside the flow channel.

[0004] Secondly, in the welding of flow channel plates, the flow channel plates are placed directly on the welding equipment. During welding, the operator needs to align the welding rod. However, during welding, after the flow channel is formed by welding between flow channel plates, the thickness of the flow channel changes, the clamping force disappears, and the welding position is easy to loosen, affecting the weld quality. Utility Model Content

[0005] The purpose of this utility model is to provide a novel welding structure for preventing welding overflow in water-side flow channel plates. By setting up a support base, lifting plate, upper U-shaped frame, upper flow channel plate and lower flow channel plate, it solves the problems of easy overflow during welding of water-side flow channel plates, which affects the stability of fluid flow, and the loss of clamping force after welding, which makes the welding position easy to be misaligned and affects the quality of the weld.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a novel welding structure for preventing welding overflow in water-side flow channel plates. It includes a support base, a lifting plate, an upper U-shaped frame, an upper flow channel plate, and a lower flow channel plate. Three lower U-shaped frames are fixed to the top of the support base along a center line parallel to its long side. A lower flow channel plate is positioned above all the lower U-shaped frames. An upper flow channel plate is positioned above the lower flow channel plate, and a lifting plate is positioned above the upper flow channel plate. Compression springs are fixed to the two short sides of the bottom of the lifting plate, and upper U-shaped frames are fixed to the bottom ends of the two compression springs. During operation, the support base supports the lifting plate, upper U-shaped frames, upper flow channel plate, and lower flow channel plate. As the lifting plate descends, it causes the upper U-shaped plate to descend as well. Simultaneously, a limiting component is connected to the upper U-shaped plate. The upper and lower flow channel plates work together to form a complete heat dissipation channel.

[0008] Furthermore, each of the lower U-shaped frames is rotatably connected to a limiting component, and the lower part of each of the upper U-shaped frames is also rotatably connected to a limiting component. The limiting component in the lower U-shaped frame restricts the lower flow channel plate, and the limiting component in the upper U-shaped frame restricts the upper flow channel plate.

[0009] Furthermore, electric push rods are fixed at the four corners of the top of the support base, and each electric push rod has a fixed block at its telescopic end. The four fixed blocks are respectively fixed at the two short sides on both sides of the lifting plate. The electric push rods drive the fixed blocks to rise and fall, thereby driving the lifting plate to rise and fall.

[0010] Furthermore, each of the compression springs has a telescopic rod fixed to the bottom of the lifting plate, and the telescopic ends of the two telescopic rods are respectively fixed to the top center of the two upper U-shaped frames. The telescopic rods in the compression springs cooperate to make the upper U-shaped frames rise and fall vertically.

[0011] Furthermore, the limiting component includes a support shaft, a limiting disk one, and a limiting disk two. Both ends of the support shaft are fixed with limiting disk one, and the end of each limiting disk one away from the support shaft is fixed with limiting disk two. The limiting component in the lower U-shaped frame includes two limiting disks two rotatably connected to the two side walls of the lower U-shaped frame. The limiting component in the upper U-shaped frame includes two limiting disks two rotatably connected to the two side walls of the upper U-shaped frame. During operation, the limiting component, through the support shaft, limiting disk one, and limiting disk two, cooperates to restrict the upper flow channel plate and the lower flow channel plate.

[0012] Furthermore, L-shaped welding strips are fixed on both sides of the upper and lower flow channels. The two L-shaped welding strips on the same side of the upper and lower flow channels are symmetrically arranged and in contact with each other. The upper flow channel is positioned between the two limiting discs 1 included in the upper U-shaped frame limiting component, and the L-shaped welding strips on both sides of the upper flow channel are positioned between the two limiting discs 2 included in the upper U-shaped frame limiting component. The lower flow channel is positioned between the two limiting discs 1 included in the lower U-shaped frame limiting component, and the L-shaped welding strips on both sides of the lower flow channel are positioned between the two limiting discs 2 included in the lower U-shaped frame limiting component. The upper and lower flow channels cooperate, and after the two L-shaped welding strips are welded together, the upper and lower flow channels are connected together.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of material overflow affecting fluid flow stability during the welding of water-side flow channel plates by setting up an upper flow channel plate and a lower flow channel plate. After the upper flow channel plate and the lower flow channel plate are put together, welding can be carried out. During welding, after the L-shaped welding strip on the upper flow channel plate is welded, the flange formed by welding is set on the inner wall of the L-shaped welding strip. After welding, the upper flow channel plate and the lower flow channel plate are in contact with each other and set together to prevent the flange formed by welding from entering between the upper flow channel plate and the lower flow channel plate. This makes it less likely for material to overflow during the welding of the water-side flow channel plate and ensures the stability of fluid flow.

[0015] This invention solves the problems of lost clamping force after welding of the water-side flow channel plate, easy misalignment of the welding position, and impact on weld quality by setting up a support base, lifting plate, upper U-shaped frame, upper flow channel plate, and lower flow channel plate. In operation, the upper and lower flow channel plates are first joined together, and then the lower flow channel plate is placed on the support shaft inside the lower U-shaped frame. As it moves, the support shaft rotates, and simultaneously, an electric push rod drives the upper U-shaped frame to descend, causing it to descend until it reaches its final position. The support shaft is pressed onto the upper flow channel plate. At this time, the first limiting disc in the upper U-shaped frame restricts both sides of the upper flow channel plate, while the second limiting disc clamps and restricts the L-shaped welding strips on both sides of the upper flow channel plate. Meanwhile, after the lower flow channel plate and its upper L-shaped welding strips are restricted by the upper and lower U-shaped frames, the contact surfaces of the two L-shaped welding strips are welded by the welding equipment. During operation, it is convenient to weld between the upper and lower flow channel plates, so that the clamping force of the water-side flow channel plate disappears after welding, the welding position is not easy to be misaligned, and the weld quality is better.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-6This utility model discloses a novel welding structure for preventing welding overflow in water-side flow channel plates. It includes a support base 1, a lifting plate 2, an upper U-shaped frame 3, an upper flow channel plate 4, and a lower flow channel plate 5. Three lower U-shaped frames 101 are fixed to the top of the support base 1 along a center line parallel to its long side. During operation, the support base 1 supports the lifting plate 2, upper U-shaped frame 3, upper flow channel plate 4, and lower flow channel plate 5 on a workbench. The lower flow channel plate 5 is positioned above all the lower U-shaped frames 101, and the upper flow channel plate 4 is positioned above the lower flow channel plate 5. During operation, the upper flow channel plate 4 and lower flow channel plate 5 are joined together for welding. In operation, a lifting plate 2 is provided above the upper flow channel plate 4. After the lifting plate 2 descends, it drives the upper U-shaped frame 3 to descend, so that the limiting component 102 in the upper U-shaped frame 3 restricts the upper flow channel plate 4. The two short sides at the bottom of the lifting plate 2 are fixed with compression springs 301. When the compression springs 301 are working, they compensate for the height of the upper flow channel plate 4 after welding and maintain the position of the upper flow channel plate 4. The compression springs 301 compensate for the height of the upper flow channel plate 4 after welding through elastic deformation, and maintain the stability of the clamping force. The bottom ends of the two compression springs 301 are fixed with the upper U-shaped frame 3, and the upper U-shaped frame 3 will contain the limiting component 102 that restricts the upper flow channel plate 4.

[0027] Specifically, each lower U-shaped frame 101 is rotatably connected to a limiting component 102, and the lower part of each upper U-shaped frame 3 is also rotatably connected to a limiting component 102. The limiting component 102 on the lower U-shaped frame 101 restricts the lower flow channel plate 5, and the limiting component 102 in the upper U-shaped frame 3 restricts the upper flow channel plate 4.

[0028] Furthermore, electric push rods 202 are fixed at the four corners of the top of the support base 1. Each electric push rod 202 has a fixed block 201 fixed at its telescopic end. The four fixed blocks 201 are fixed at the two short sides of the lifting plate 2 respectively. The electric push rods 202 drive the fixed blocks 201 to rise and fall, thereby driving the lifting plate 2 to rise and fall.

[0029] Furthermore, each lifting plate 2 within the compression spring 301 is fixed with a telescopic rod 302 at its bottom. The telescopic ends of the two telescopic rods 302 are respectively fixed to the top center of the two upper U-shaped frames 3. The vertical lifting and lowering movement of the upper U-shaped frames 3 is maintained by fixing the telescopic ends of the telescopic rods 302 to the top of the upper U-shaped frames 3.

[0030] Furthermore, the limiting component 102 includes a support shaft 1021, a limiting disc 1022, and a limiting disc 2 1023. Both ends of the support shaft 1021 are fixed with limiting discs 1022, and the end of each limiting disc 1022 away from the support shaft 1021 is fixed with a limiting disc 2 1023. The two limiting discs 2 1023 included in the limiting component 102 in the lower U-shaped frame 101 are rotatably connected to the two side walls inside the lower U-shaped frame 101. The two limiting discs 2 1023 included in the limiting component 102 in the upper U-shaped frame 3 are rotatably connected to the two side walls inside the upper U-shaped frame 3. The support shaft 1021 contacts the lower flow channel plate 5 or the upper flow channel plate 4. The limiting disc 1022 restricts the sides of the upper flow channel plate 4 and the lower flow channel plate 5. The limiting disc 2 1023 restricts the L-shaped welding strips 401 on the upper flow channel plate 4 and the lower flow channel plate 5.

[0031] The operation process of this embodiment is as follows: During operation, when it is necessary to perform the operation, firstly, after the upper flow channel plate 4 and the lower flow channel plate 5 are put together, the lower flow channel plate 5 is placed on the support shaft 1021 inside the lower U-shaped frame 101. As the movement occurs, the support shaft 1021 rotates. At the same time, the electric push rod 202 drives the upper U-shaped frame 3 to descend, so that the upper U-shaped frame 3 descends until the support shaft 1021 inside the upper U-shaped frame 3 presses onto the upper flow channel plate 4. At this time, the first limiting plate 1022 inside the upper U-shaped frame 3 restricts both sides of the upper flow channel plate 4, and the second limiting plate 1023 restricts the L-shaped welding strips 401 on both sides of the upper flow channel plate 4 to be clamped and restricted. At the same time, after the lower flow channel plate 5 and its upper L-shaped welding strips 401 are restricted by the upper and lower U-shaped frames 101, the contact surfaces of the two L-shaped welding strips 401 are welded by the welding equipment. During operation, the welding between the upper flow channel plate 4 and the lower flow channel plate 5 can be conveniently performed. Specific Implementation Example 2

[0032] Please see Figure 6 Based on the first specific embodiment, L-shaped welding strips 401 are fixed on both sides of the upper flow channel plate 4 and the lower flow channel plate 5. The two L-shaped welding strips 401 on the same side of the upper flow channel plate 4 and the lower flow channel plate 5 are symmetrically arranged and in contact with each other. The upper flow channel plate 4 is located between the two limiting disks 1022 included in the limiting component 102 of the upper U-shaped frame 3, and the L-shaped welding strips 401 on both sides of the upper flow channel plate 4 are located between the two limiting disks 1023 included in the limiting component 102 of the upper U-shaped frame 3. The lower flow channel plate 5 is located between the two limiting disks 1022 included in the limiting component 102 of the lower U-shaped frame 101, and the L-shaped welding strips 401 on both sides of the lower flow channel plate 5 are located between the two limiting disks 1023 included in the limiting component 102 of the lower U-shaped frame 101. The two L-shaped welding strips 401 on the same side of the lower flow channel plate 5 and the upper flow channel plate 4 are in contact with each other, so welding can be performed.

[0033] The operation process of this embodiment is as follows: During operation, when the upper flow channel plate 4 and the lower flow channel plate 5 are put together, welding can be performed. During welding, after the L-shaped welding strip 401 on the upper flow channel plate 4 is welded, the flange formed by welding is set on the inner wall of the L-shaped welding strip 401. After welding is completed, the upper flow channel plate 4 and the lower flow channel plate 5 are in contact with each other and set together to prevent the flange formed by welding from entering between the upper flow channel plate 4 and the lower flow channel plate 5.
