Abstract

The invention discloses a heat exchange system and a motor. The heat exchange system is used for cooling a heating part of the motor, and comprises a first heat exchange unit and a second heat exchange unit, wherein the first heat exchange unit is disposed in a to-be-cooled region of the motor for heat exchange, and comprises a plurality of first heat exchange branches which are connected in parallel; the second heat exchange unit is arranged outside the motor, the second heat exchange unit is communicated with the first heat exchange unit through a pipeline assembly to form a closed-loop heatexchange loop, each first heat exchange branch is connected with a first heat exchanger, a first valve set and a first pressure information assembly, and opening and closing of the first valve set are controlled according to first pressure information of the first pressure information assembly. According to the heat exchange system and the motor provided by the embodiment of the invention, the fault-tolerant operation capability and reliability of the heat exchange system and the motor can be improved.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a heat exchange system and a motor. Background technique [0002] Wind power technology is a key technology for the development of renewable energy. During the operation of the motor of the wind power generating set, there is heat loss which mainly comes from electromagnetic loss. Heat loss mainly includes Joule heat generated by ohmic impedance in the winding, hysteresis loss and eddy current loss in the iron core, and unavoidable stray loss. [0003] With the continuous increase of wind energy development, the single installed capacity of wind power generators is constantly rising. The increase of stand-alone capacity will directly bring about the continuous improvement of the heat loss of wind power generators. As an important part of the wind turbine, the cooling system can take away the heat generated by the wind turbine to a certain extent, so as to facilitate the smooth ope...
