一种机车车辆冷却系统用散热器
By designing an auxiliary air vent structure for the air intake and exhaust mechanisms, the system utilizes both ambient and traveling air to enter the radiator, thus solving the problems of poor heat dissipation at low speeds in locomotive and EMU cooling systems and high noise and energy consumption in forced ventilation liquid cooling systems, achieving a highly efficient and low-energy-consumption cooling effect.

AI Technical Summary
The traction equipment of locomotives and EMUs requires continuous and efficient cooling capabilities, but the existing running air cooling system has poor heat dissipation effect at low speeds, while increasing the size of the radiator will lead to cost and space layout problems, and the forced ventilation liquid cooling system is noisy and energy-intensive.
Design a radiator for a locomotive and rolling stock cooling system, comprising an air intake mechanism and an air outlet mechanism. Through the design of an auxiliary air vent, ambient wind and running wind are combined to enter the radiator, thereby improving the efficiency of cooling air utilization and reducing energy consumption and noise.
It improves the heat dissipation capacity of radiators, reduces energy consumption and noise, and is suitable for high-power locomotives and high-speed trains, providing a heat dissipation solution under multiple air supply conditions.
