Damp-proof heat dissipation device for motor of cooling tower

The utility model discloses a moisture-proof heat dissipation device for a motor of a cooling tower, which comprises an air duct, a protective sleeve is arranged in the air duct, a motor is arranged in the protective sleeve, a fan is connected onto the motor and is positioned in the air duct, a plurality of heat dissipation pipes are arranged on the protective sleeve and extend out of the air duct, and the protective sleeve is connected with the motor. Cooling air blown out by the fan is firstly absorbed through the heat dissipation pipe, moisture contained in the heat dissipation pipe is low, the probability that the motor is affected with damp can be effectively reduced through protection of the external protection sleeve, and meanwhile heat dissipation is guaranteed. 本实用新型公开了一种冷却塔电动机防潮散热装置，包括风筒，风筒内设置有防护套筒，所述防护套筒内设置有电动机，所述电动机上连接有风扇，且风扇位于风筒内，所述防护套筒上设置有若干散热管，所述散热管延伸至风筒外，通过散热管先吸收风扇吹出的冷却空气，其内部含有的水分较低，再加上外部防护套筒的防护，能够有效降低电动机受潮的概率，同时保证散热。
