Generator cooling device with vertical low-resistance heat pipes

Abstract

The invention discloses a generator cooling device with vertical low-resistance heat pipes, comprising multiple heat pipes, a hot-side circulation fan, and a cold-side water tank. The condensation ends of the heat pipes are in the cold-side water tank, and the evaporation ends of the heat pipes are in a generator cabin. The outer wall of each heat pipe is configured with a high-density multi-layer and multi-column linear bent heat exchange member, and the linear bent heat exchange member is composed of a first bent part, a second bent part, a third bent part, a fourth bent part and a fifth bent part which are formed by bending a metal wire four times. A bracket is arranged at the bottom of the evaporation ends of the heat pipes, and the bracket is fixed on a liquid collecting tray. The heat pipes are used as heat exchange elements, and a generator can be cooled quickly. The condensation ends of the heat pipes are in the cold-side water tank, so the heat generated by generators is fully utilized, and energy saving is achieved. The bracket is fixed on the liquid collecting tray, so the working liquid in the heat pipes does not flow to generators after the heat pipes leak accidentally, and a generator short circuit accident is avoided.

Description

technical field [0001] The invention relates to a generator cooling device, in particular to a generator cooling device with vertical low-resistance heat pipes. Background technique [0002] The wind turbine generates a lot of heat during the working process, which must be dissipated as soon as possible to ensure the normal operation of the generator set. Now the commonly used cooling device of the wind turbine first transfers the heat generated by the generator set to the generator set arranged in the generator box. Water radiator or oil radiator, and then through the heat exchanger outside the generator box for heat dissipation, the heat exchange efficiency of this device is not ideal, and the heat generated by the generator set during operation cannot be effectively used, resulting in waste of energy. Contents of the invention [0003] In order to solve the above problems, the present invention provides a generator cooling device with vertical low-resistance heat pipes....
