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.

[embodiment]
A kind of radiator structure of wind electric converter rack; Be provided with dividing plate 2 in the said wind electric converter rack 1; Dividing plate 2 is divided into cabinet internal layer 11 and cabinet outer 12 with the rectifier cabinet cabinet; Described cabinet internal layer 11 all is provided with air inlet 13 with the bottom of cabinet outer 12, and described cabinet internal layer 11 is equipped with air exhausting device 14 with the top of cabinet outer 12.
Described air exhausting device 14 comprises outer extractor fan 141 and interior blowing device 142.
Extractor fan 141 is an air exhauster in described, and air exhauster directly is installed on the upper wall of cabinet internal layer 11, gets into rectifier cabinet in order to prevent dust, also in order to protect air exhauster, also is provided with a protective cover 1410 on the top of air exhauster.When air exhauster was worked, air-flow got into from air inlet 13, in rectifier cabinet, carries out heat exchange, reduces the temperature of cabinet internal layer 11 in the rectifier cabinet.
Blowing device 142 comprises centrifugal blower 1421 in described, and the outlet air end of centrifugal blower 1421 is provided with heat abstractor 143.Described heat abstractor 143 comprises the heat dissipation wind channel 1431 that communicates with wind pipe 1421, is provided with radiator 1432 in the heat dissipation wind channel 1431, and radiator 1432 comprises a plurality of fin, and each fin gap forms air-out passage aisle 1433.After centrifugal blower 1421 work, air-flow gets into from air inlet 13, and passes through from air-out passage aisle 1433; Fin 1432 dispels the heat; Under the blowing effect of centrifugal blower, can reduce the temperature of power model rapidly, protected power model because of the too high paralysis that causes of generating heat.
