AI Technical Summary
Technical Problem
Current vehicle water-cooled radiators fail to meet the market's increasing demands for reduced manufacturing cost and improved heat dissipation performance, particularly for IGBT and ADAS applications.
Method used
A vehicle water-cooled radiator design featuring an upper and lower cover with a curved flow channel, laser welding structures, and protrusions or needle-shaped fin groups on the lower cover to enhance heat dissipation and sealing, made from stamped or forged aluminum alloy for improved efficiency and cost-effectiveness.
Benefits of technology
The design achieves better heat dissipation capacity, lower manufacturing costs, and lighter weight while avoiding issues like gas retention pores, with enhanced heat dissipation and pressure resistance.

Abstract
A vehicle water-cooled radiator includes an upper cover and a lower cover. A curved flow channel for a cooling liquid to flow is formed between the upper cover and the lower cover. The curved flow channel has multiple flow channel cavities and at least two water holes communicated with the flow channel cavities. A first laser welding structure surrounding the curved flow channel is formed between the upper cover and the lower cover, and a second laser welding structure is formed between the upper cover and the lower cover and between two adjacent flow channel cavities. The lower cover has a first contact surface and a second contact surface. The first contact surface contacts the cooling liquid flowing through the flow channel cavities. The lower cover has multiple protrusions disposed on the second contact surface, and at least two protrusions are different in shape from the other protrusions.
