AI Technical Summary
During the use of existing electric vehicle low-temperature radiators, due to the small welding area between the circular current collector and the circular water pipe, the strength is insufficient, and core leakage is easily caused by poor environment.
A combination of two current collecting pipe joints and several flat pipes arranged vertically on the left and right sides were designed. The flat pipe was connected with fins, and both the two current collecting pipes were connected with joint water pipes. The joint water pipes were made of saddle structure, and water pipes were added. The contact welding area with the low-temperature radiator is provided with a bracket and a clamp on the outer wall of the collector joint to enhance the clamping force.
