For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0018] Currently, the assembly methods of automotive radiator assemblies can be divided into aluminum-plastic press-fitting type and all-aluminum welding type. Among them, in the welding process of the water chamber and the core body of the all-aluminum welding type, the core body is welded first and then sealed and welded with the water chamber to form a radiator assembly.

[0019] However, the welded assembly after this method has problems such as large local weld beads and uncontrollable weld bead directions, and the step-by-step welding of the core body and the assembly welding will lead to defects such as low production capacity, low efficiency, and energy inefficiency.

[0020] Therefore, the design concept of this application is to design a water chamber main piece connection structure that can achieve the integral welding of the water chamber and the core body, so as to change the process flow of brazing the core body alone in a brazing furnace and then sealing and welding it with the water chamber.

[0021] As Figures 1-4 shown, this application provides a connection structure for the main piece of an integrally brazed radiator, which is used to connect the water chamber 1 and the main piece 3. A water chamber flange 2 is provided at the edge of the water chamber 1, and a main piece flange 4 is provided at the edge of the main piece 3; a plurality of tooth grooves 5 are provided on the main piece flange 4, and a press-fit tooth 6 is provided in the tooth groove 5; the main piece flange 4 is snap-fitted with the water chamber flange 2, and the press-fit tooth 6 is press-fit and snapped with the water chamber flange 2.

[0022] During installation, first, the main piece 3 is clamped at the bottom of the water chamber 1. At this time, the main piece flange 4 is clamped outside the water chamber flange 2. Then, a press-fitting machine or other tools are used to bend the press-fit tooth 6, and the press-fit tooth 6 is press-fit and snapped onto the water chamber flange 2. The connection between the main piece 3 and the water chamber 1 is completed, and then the next operation can be carried out.

[0023] The tooth grooves 5 can be set to 4 - 6. For the specific quantity, the user can determine it according to the size of the tooth groove 5, the size of the press-fit tooth 6, or the size of the main piece 3.

[0024] This application provides an all-aluminum automotive radiator structure with a simple structure, reasonable design, and high welding efficiency. Its main feature lies in the matching structure between the main piece and the water chamber. Before welding, after the press-fit teeth on the main piece are connected in cooperation with the flange of the formed water chamber, other accessories are spot-welded and fixed. Finally, a tool is used to weld the water chamber and the core body together in a brazing furnace, and after welding, the water chamber and the core body are integrated into one.

[0025] This application uses integral welding of the water chamber and the core body when entering the furnace, reducing the technological process of separately sealing and welding the radiator core body and the water chamber. This significantly improves the cleanliness inside the radiator and greatly enhances the surface appearance quality. There are no welding slag, welding tumors, etc. on the surface. Reducing one-step argon arc welding has a positive effect on energy conservation and environmental protection and also reduces production costs.

[0026] The purpose achieved by the radiator of this application is that after fixing the water chamber and the core body of the radiator, they are welded together in a brazing furnace, changing the technological process of separately welding the core body in the brazing furnace and then sealing and welding it with the water chamber.

[0027] This application also provides an integrally brazed radiator, including a water chamber 1 and a main fin 3. The connection structure between the water chamber 1 and the main fin 3 adopts the connection structure of the water chamber and main fin of the above integrally brazed radiator.

[0028] For this integrally brazed radiator, after being connected by the connection structure of the water chamber and main fin of this integrally brazed radiator, the water chamber and the core body become a whole to be welded. That is, after welding, the water chamber and the core body become an integral whole. There are no welding tumors after welding, effectively solving the thermal stress during the welding process of the radiator core body, reducing the traditional assembly welding step, greatly improving production efficiency, avoiding resource waste, and reducing production costs.

[0029] Although the present utility model has been described in detail by referring to the accompanying drawings and in combination with preferred embodiments, the present utility model is not limited thereto. Without departing from the spirit and essence of the present utility model, those of ordinary skill in the art can make various equivalent modifications or substitutions to the embodiments of the present utility model, and these modifications or substitutions should all be within the scope covered by the present utility model. / Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
