Description

Technical Field

[0001] This utility model relates to the field of radiator manufacturing technology, specifically to a water chamber of a press-fit furnace-welded radiator. Background Technology

[0002] In existing radiators, the water chamber and the core are usually connected by argon arc welding. The water chamber is usually a C-shaped structure with one side open and both ends closed. During assembly, the open side of the water chamber needs to be pressed tightly onto the side plate of the core before welding.

[0003] The existing connection method between the core and the water chamber has the following shortcomings:

[0004] 1. There are many welding points in the part that fits with the core side plate, which require workers to weld them one by one using argon arc welding, resulting in low production efficiency.

[0005] 2. The connection between the core and the water chamber relies solely on welds, which concentrates stress and makes the welds prone to cracking, leading to water leakage from the water chamber and affecting its service life.

[0006] 3. The lack of limiting components during welding makes it easy for displacement to occur, affecting welding efficiency and welding quality.

[0007] To address the problems existing in the prior art, this utility model designs and manufactures a water chamber for a press-fit furnace-welded radiator to overcome the aforementioned defects. Utility Model Content

[0008] To address the problems existing in the prior art, this utility model provides a water chamber for a press-fit furnace-welded radiator, which can improve production efficiency and quality, and extend service life.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water chamber for a press-fit furnace-welded radiator includes two connecting plates and two C-shaped main plates. The connecting plates are symmetrically installed at both ends of the core. Each end of the C-shaped main plate is equipped with a sealing plate. One side of the connecting plate is connected to the core, and the other side of the connecting plate is connected to the unsealed side of the C-shaped main plate. The side of the sealing plate closest to the core is connected to the connecting plate.

[0010] The upper and lower ends of the C-shaped main board are provided with U-shaped plates on the side near the connecting plate, and the two ends of the connecting plate are provided with connecting end ribs, which can slide and cooperate with the U-shaped plates.

[0011] The contact surface between the connecting end rib and the U-shaped plate is provided with a solder layer. The U-shaped plate is pressed tightly to deform it and press it against the solder layer for furnace brazing.

[0012] Preferably, the shape of the sealing plate matches the outer contours of both ends of the C-shaped main board.

[0013] Preferably, the sealing plate is connected to the C-shaped main board and the connecting plate by argon arc welding.

[0014] Preferably, the U-shaped plate and the C-shaped main plate are connected by being integrally formed.

[0015] Preferably, the length of the U-shaped plate is equal to the length of the connecting end rib.

[0016] Preferably, the height of the connecting end rib is the same as the height of the inner diameter of the U-shaped plate.

[0017] Preferably, the width of the inner wall of the U-shaped plate is greater than the width of the connecting end rib.

[0018] Preferably, the connection end rib and the connection plate are integrally formed.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model sets two U-shaped plates on the C-shaped main board and two connecting end ribs on the connecting plate. During assembly, the two U-shaped plates can restrict the relative movement of the C-shaped main board and the core in the vertical direction. By clamping the U-shaped plates and deforming them to press them tightly against the connecting end ribs, the relative movement of the two can be completely restricted, thus improving the welding quality.

[0021] 2. This utility model has a solder layer on the connecting end rib. Pressing the U-shaped plate will make its inner wall contact the solder layer and fix the U-shaped main plate. Multiple water chambers to be welded can be placed in the brazing furnace for welding at the same time, which improves production efficiency.

[0022] 3. The height of the connecting end rib of this utility model is the same as the inner diameter height of the U-shaped plate, and the solder layer completely covers the contact surface between the connecting end rib and the U-shaped plate. The U-shaped plate completely wraps the two sides and one end face of the connecting end rib, and the contact surfaces are all connected by solder. Compared with the connection of a single weld, the connection strength is higher, the stress is distributed and there will be no weld cracking, thus extending the service life.

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1-3 The water chamber of a press-fit furnace-welded radiator shown includes two connecting plates 6 and two C-shaped main plates 1. The C-shaped main plates 1 are formed by bending sheet metal, which reduces the number of welds and improves the overall strength.

[0029] In this invention, connecting plates 6 are symmetrically installed at both ends of the core 3, and sealing plates 7 are installed at both ends of the C-shaped main board 1. The shape of the sealing plates 7 matches the outer contour of both ends of the C-shaped main board 1, and can completely seal both ends of the C-shaped main board 1. One side of the connecting plate 6 is connected to the core 3, and the other side of the connecting plate 6 is connected to the unsealed side of the C-shaped main board 1.

[0030] Specifically, the side of the sealing plate 7 closest to the core 3 is connected to the connecting plate 6, and the sealing plate 7 is connected to the C-shaped main plate 1 and the connecting plate 6 by argon arc welding. Two complete closed water storage chambers are formed on both sides of the core 3.

[0031] The main board 1 of this utility model has U-shaped plates 2 on both the upper and lower ends near the connecting plate 6. The U-shaped plates 2 and the main board 1 are integrally formed. Both ends of the connecting plate 6 are provided with connecting end ribs 5. The connecting end ribs 5 and the connecting plate 6 are integrally formed, which improves the connection strength and ensures the integrity.

[0032] Specifically, the width of the inner wall of the U-shaped plate 2 is greater than the width of the connecting end rib 5. The connecting end rib 5 can slide with the U-shaped plate 2 and can move arbitrarily along the length of the connecting end rib 5, making it convenient to insert the U-shaped main plate 1 into the connecting plate 6.

[0033] Specifically, the connecting end rib 5 can play a certain guiding and limiting role in the installation of the C-shaped main board 1. During assembly, the two U-shaped plates 2 can restrict the relative vertical movement of the C-shaped main board 1 and the core 3. The length of the U-shaped plate 2 is equal to the length of the connecting end rib 5. The positioning of the lateral movement of the C-shaped main board 1 can be achieved simply by aligning either end of the C-shaped main board 1 and the U-shaped plate 2, which improves production efficiency.

[0034] Specifically, after positioning, the U-shaped plate 2 is clamped and deformed to press firmly against the connecting end rib 5, which completely restricts the relative movement between the two and completely fixes the U-shaped main plate 1 to the core 3. This prevents displacement during subsequent welding or transportation, improving welding quality.

[0035] The contact surface between the connecting end rib 5 and the U-shaped plate 2 of this utility model is provided with a solder layer 4. Pressing the U-shaped plate 2 to deform it and press it tightly against the solder layer 4 allows multiple devices to be welded to be placed together in the brazing furnace for welding, improving production efficiency, reducing the number of welds that welders manually weld, and reducing labor costs and labor intensity.

[0036] Specifically, the height of the connecting end rib 5 is the same as the inner diameter height of the U-shaped plate 2. Furthermore, the solder layer 4 completely covers the contact surface between the connecting end rib 5 and the U-shaped plate 2. The U-shaped plate 2 completely wraps around both sides and one end face of the connecting end rib 5, and all contact surfaces are connected by solder. Compared to a single weld connection, this method distributes stress more evenly, resulting in higher connection strength, preventing weld cracking, and extending service life.

[0037] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
