[0003] However, since the air in the production workshop is accompanied by dust and even water, the fan directly blows the motor to easily blow the dust in the air into the motor. At the same time, the dust stays in the joints of the motor parts, which affects the cooperation between the parts and accelerates the wear of the parts

The invention relates to the technical field of a radiator and specifically to a fully-sealed collecting ring cooling structure used for cooling a motor. The fully-sealed collecting ring cooling structure comprises a thermal conductive apparatus connected with the motor; the fully-sealed collecting ring cooling structure also comprises a ring cooling chamber, a radiating chamber, an internal circulating fan and an external circulating fan; the ring cooling chamber is arranged in the radiating chamber; the internal circulating fan and the external circulating fan are arranged on the exterior of the radiating chamber; a circulating air channel is formed in the ring cooling chamber; the thermal conductive apparatus is arranged in the circulating air channel; the air outlet of the internal circulating fan is connected with the circulating air channel through an air pipe; an opening is further formed in the radiating chamber; the external circulating fan is arranged in the opening; and the air outlet of the external circulating fan faces to the ring cooling chamber. According to the scheme, the motor and the external circulating fan are fully isolated, so that air around the motor is prevented from entering the motor, and dusts and water are prevented from entering the collecting ring, so that the blocking of the motor and the degradation of the insulating property of the collecting ring are avoided; and in addition, the probability of parts abrasion caused by dusts is eliminated, and the service life of the motor is prolonged.
Description
technical field [0001] The invention relates to the technical field of heat dissipation devices, in particular to a fully enclosed collector ring cooling structure. Background technique [0002] When the motor is converting energy, part of the loss is always converted into heat. It must continuously dissipate heat through the motor casing and the surrounding medium. This dissipating process is the cooling of the motor. The cooling methods of the motor generally include natural cooling, forced air cooling, wind-air cooling, wind-water cooling, and water cooling. For air cooling, a fan is arranged around the motor to take away the heat from the motor casing and surroundings through the flow of air, accelerate the heat dissipation of the motor, and cool the motor quickly, which is a way better than natural cooling. [0003] However, because the air in the production workshop is accompanied by dust, even water, the fan directly blows the motor to easily blow the dust in the air...
