Problems solved by technology
However, for some new variable frequency motors and new DC motors, their working conditions vary greatly. When natural convection cooling and forced convection cooling cannot meet the heat dissipation requirements, an additional active cooling system is required to provide cooling capacity to control the temperature of the motor. Lift
The common compression refrigeration method has a high refrigeration coefficient, but has defects such as complex system and severe vibration, which is not conducive to the long-term efficient operation of the motor

The invention discloses a full-sealed motor cooling system which comprises a box body (6). A fixed support (3) is arranged in the box body (6), a plurality of radiating fins (4) are arranged on the fixed support (3), semiconductor refrigerating assemblies (2) are correspondingly arranged at the bottom ends of the radiating fins (4), the bottom ends of the semiconductor refrigerating assemblies (2) are attached to a casing of a motor (1) sealed at the bottom of the box body (6), a venting opening (7) is formed in the upper portion of the box body (6), and an exhausting fan (5) is correspondingly arranged at the area, close to the radiating fins (4), of one side of the venting opening (7). The semiconductor refrigerating assemblies can cool the sealed motor, so that refrigerants are avoided, leakage is avoided, and vibration is avoided. The full-sealed motor cooling system can be obliquely arranged or reversely arranged at any angle and is small in size and high in reliability.
Description
technical field [0001] The invention relates to a cooling system of a totally enclosed motor. Background technique [0002] The fully enclosed shell protection structure of common fully enclosed motors can effectively prevent a large amount of dust and water vapor in the environment from entering the motor, thereby ensuring the stability of the insulation performance and damping performance inside the motor. heat dissipation. [0003] At present, in order to prevent the motor from overheating, most of the fully enclosed motors are equipped with a heat dissipation rib structure on the casing, and use natural air convection to dissipate heat or an external fan to force convection to dissipate heat. In the case of stable working conditions, for common three-phase AC asynchronous motors, the natural convection heat dissipation and forced convection heat dissipation can basically meet the requirements. However, for some new variable frequency motors and new DC motors, their wor...
