The invention discloses a multi-channel power supply device of a battery changing cabinet and a control method, and belongs to the technical field of power supply equipment, the multi-channel power supply device comprises a cabinet body, a power supply unit for multi-channel power supply and a heat dissipation fan, a heat dissipation mechanism for efficient heat dissipation is arranged in the cabinet body, and the heat dissipation mechanism comprises a flow guide pipe communicating the upper end and the lower end in the cabinet body; air inducing grooves are formed in the two sides of the flow guiding pipe, pressurizing pipes corresponding to the air inducing grooves are fixedly connected to the inner side face of the flow guiding pipe, and heat dissipation grooves corresponding to the air inducing grooves are formed in the two sides of the cabinet body. Drainage is carried out through cooperation of a flow guide pipe and a pressurizing pipe, so that external air can penetrate through a heat dissipation groove to enter the cabinet body and can be in contact with the surface of the power supply unit for heat exchange in the process of entering the flow guide pipe, and therefore, good cooling treatment can be carried out on the power supply unit; and the conditions of easy failure and serious shortening of service life caused by continuously higher temperature are avoided.

    本发明公开了一种换电柜的多路供电装置及控制方法,属于供电设备技术领域,包括柜体、用于多路供电的供电单元以及散热风扇,所述柜体的内部设置有用于高效散热的散热机构,所述散热机构包括连通柜体内部上下两端的导流管,所述导流管两侧开设有引风槽,所述导流管的内侧面固定连接有与引风槽对应的增压管,所述柜体的两侧开设有与引风槽对应的散热槽。通过导流管以及增压管的配合下进行引流,使得外界的空气可以穿过散热槽进入柜体内部并进入导流管内部的过程中,可以与供电单元的表面接触换热,从而可以对其进行很好的降温处理,避免了其温度持续较高导致容易故障以及使用寿命严重缩短的情况发生。
