Description

Technical Field

[0001] This utility model relates to the field of heavy-duty truck radiator technology, and in particular to a water chamber for a heavy-duty truck radiator welded by vibration friction welding. Background Technology

[0002] Heavy truck radiators are one of the important components of current engine cooling systems. Traditional all-aluminum radiators are not only heavy, but also have high welding process and metal material costs. Therefore, intercoolers with plastic air chambers have become the mainstream trend.

[0003] In existing technologies, the water chamber structure and expansion tank are usually designed and formed separately, which makes space arrangement difficult and costs high. Moreover, most radiator water chamber welding methods use hot plate welding technology, which may lead to deformation and leakage failure under the high temperature and high pressure of radiators, affecting the quality of radiators. In addition, hot plate welding technology has disadvantages such as high energy consumption, low efficiency and slow cycle time, which makes it too expensive for mass production at high speed. Therefore, we propose a heavy truck radiator water chamber welding method using vibration friction welding. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a heavy-duty truck radiator water chamber welded by vibration friction welding. The purpose is to optimize the spatial layout of the radiator to reduce costs, improve the strength of the radiator water chamber to reduce deformation, leakage, and failure, and improve production efficiency to reduce costs.

[0005] The technical solution of this utility model is:

[0006] A heavy-duty truck radiator water chamber manufactured by vibration friction welding includes an expansion tank and a water chamber. The expansion tank is divided into two parts: an upper expansion tank formed separately, and a lower expansion tank formed integrally with the water chamber. The two parts are welded together by vibration friction welding technology to form a complete heavy-duty truck radiator water chamber.

[0007] In a further technical solution, a coolant filling port is provided on the outer side of the upper expansion tank, a coolant filling port is provided on the inner bottom side of the upper expansion tank, and a coolant filling port is provided in the middle of the inner part of the upper expansion tank.

[0008] In a further technical solution, raised friction ribs are provided on the friction contact surfaces of the lower expansion tank and the upper expansion tank.

[0009] In a further technical solution, the top of the lower expansion tank is provided with a positioning post that is accurately connected to the upper expansion tank.

[0010] In a further technical solution, the lower expansion tank is connected to the water chamber, the lower expansion tank is provided with a flow limiting valve channel for installing a flow limiting valve, and the water chamber is also provided with a coolant inlet and outlet.

[0011] The beneficial effects of this utility model are:

[0012] Compared with existing technologies, this device achieves fusion of the upper and lower parts through vibration friction welding, which not only reduces production costs and improves production efficiency, but also improves the sealing and strength of the expansion tank, thus enhancing the overall safety and reliability of the radiator water chamber. Furthermore, the radiator water chamber and air chamber are connected to the expansion tank using injection molding, resulting in an integrated design of the water chamber and expansion tank. The advantages are: firstly, space optimization and structural compactness, saving costs; secondly, reducing parts, materials, and weight to achieve lightweight design; and finally, the integrated design reduces leakage points and improves the system's sealing and reliability.

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example:

[0022] like Figures 1-4As shown, a heavy-duty truck radiator water chamber is welded by vibration friction. The radiator water chamber is made of high-temperature resistant, high-strength plastic and has mounting holes at both ends. The outer shell of the water chamber is provided with mesh-like reinforcing ribs.

[0023] The radiator's water chamber and air chamber are connected together using an injection molding process, which means that the water chamber and expansion tank are integrated into one design. The advantages are: firstly, space optimization and structural compactness, saving costs; secondly, reducing parts, materials, and weight to achieve lightweight design; and finally, the integrated design can reduce leakage points and improve the system's sealing and reliability.

[0024] In another embodiment, the expansion tank is divided into two parts. One part is formed separately as the upper expansion tank 30, and the other part, the lower expansion tank 20, is directly integrally formed with the water chamber 10. The two parts are finally welded together by vibration friction welding technology to form a complete heavy-duty truck radiator water chamber. The fusion of the upper and lower parts through vibration friction welding not only reduces production costs and improves production efficiency, but also improves the sealing and strength of the expansion tank, thereby enhancing the overall safety and reliability of the radiator water chamber.

[0025] In another embodiment, the separately formed upper expansion tank 30 is provided with a coolant filling port 31, a pressure relief port 33, and a plastic rod 34 for mounting a float, which is used to detect the water level of the coolant in the tank.

[0026] In another embodiment, the lower expansion tank 20, which is integrally formed with the water chamber 10, has raised friction ribs 21 on the friction contact surface with the upper expansion tank. The friction ribs 21 are melted by the heat generated by high-speed vibration friction, and under the coverage of the outer edge 32 of the upper expansion tank, they are fused with the same material to the internal contact surface, thereby improving reliability.

[0027] In another embodiment, the lower expansion tank 20, which is integrally formed with the water chamber 10, is provided with a positioning post 23 that is accurately connected to the upper expansion tank, thereby improving the accuracy of the upper and lower mold closing positions.

[0028] In another embodiment, the water chamber is connected to the expansion tank, and the channel 22 for installing the flow limiting valve is provided in the lower expansion tank 20. The water chamber 10 is also provided with a coolant inlet and outlet 11. The flow limiting valve controls the coolant to expand and enter the expansion tank to maintain pressure balance.

[0029] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
