Abstract
The utility model discloses a heat radiation structure of a wind power converter cabinet. A separator plate is disposed inside a cabinet to divide the body of the rectification cabinet into an inner cabinet layer and an outer cabinet layer. Both the bottom of the inner cabinet layer and the bottom of the outer cabinet layer are provided with air inlets. Both the top of the inner cabinet layer and the top of the outer cabinet layer are equipped with air-discharge devices. According to the heat radiation structure of the utility model, the separator plate is disposed inside the rectification cabinet to divide the body of the rectification cabinet into the inner cabinet layer and the outer cabinet layer, the air inlets are arranged both on the bottom of the inner cabinet layer and the bottom of the outer cabinet layer, and the air-discharge devices are disposed both on the top of the inner cabinet layer and the top of the outer cabinet layer. Each air-discharge device comprises internal blowing devices and an external ventilation device which is a centrifugal blower fan. When the centrifugal blower fan is running, air flow enters from the air inlets and heat exchange occurs inside the wind power converter cabinet to reduce the temperature inside the cabinet. Each internal blowing device comprises an air channel, the air intake end of the air channel is provided with a multi-wing centrifugal blower fan, and the air-out end of an air-out pipeline is equipped with a heat radiation apparatus. The heat radiation structure of a wind power converter cabinet is simple in structure, low in cost, reasonable in design and convenient in maintenance, and exhibits a fine heat radiation effect.
