Internal coil heat dissipation system of micro turbine generator set

Abstract

The invention discloses an internal coil heat dissipation system of a micro turbine generator set. The internal coil heat dissipation system comprises a base plate and a generator shell, wherein a stator coil and a rotor are arranged on the inner wall of the generator shell, an air cooling device and a water cooling device are arranged on the side wall of the generator shell, the air cooling device comprises a tangent air inlet part, a tangent air exhaust part, a flow speed control part arranged on the outer wall of the tangent air inlet part and a heat source gas collecting part arranged at the air exhaust end of the tangent air exhaust part, the water cooling device comprises a first water tank, a second water tank, an air inlet cooling part arranged outside the tangent air inlet part in a sleeve mode, a shell cooling part arranged on the side wall of the generator shell in a sleeve mode, and stator direct cooling parts annularly arranged on the inner wall of the generator shell in an array mode, one side of the stator direct cooling part is provided with a heat-conducting moisture-absorbing part, and one end of the heat-conducting moisture-absorbing part communicates with the heat source gas collecting part through a transmission part. According to the internal coil heat dissipation system, the influence of cooling airflow on the rotor is small, and condensate water is prevented from influencing normal work of the generator.

Description

technical field [0001] The invention mainly relates to the technical field of turbogenerators, in particular to a cooling system for electric coils inside a microturbine generator set. Background technique [0002] A generator is a mechanical device that converts mechanical energy into electrical energy. Its main principle is to cut the lines of magnetic induction to generate electricity. When the generator is working, its internal coils will generate heat. Overheating inside the generator will affect the working efficiency of the generator. [0003] According to the internal heat dissipation system of a turbine generator provided by the patent document with the application number CN202110443476.2, it can be known that the product includes a generator and a radial turbine connected to the input end of the generator. There is a heat dissipation component, and the rotor is connected to the inner axis of the generator, and the rotor outer cover is provided with a stator fixed i...
