Problems solved by technology

[0004] However, in actual work, after the coolant enters the first cooling chamber from the inlet pipe, since there is no obstruction in the first cooling chamber, the coolant is output from the outlet pipe at the other end of the first cooling chamber after a short stay, cooling The residence time of the liquid in the first cooling chamber is short, and the heat exchange is not complete, which easily causes waste of energy and reduces the utilization efficiency of the cooling liquid

Abstract

The invention discloses an efficient brushless generator, in a power generation equipment field, the invention solves the technical problem of low utilization rate of coolant in the prior art, the advantage of that technical scheme are as follows, includes a housing and a rotating shaft rotatably arranged in the housing, a first cooling chamber is arranged in the shell, a liquid inlet pipe and a liquid outlet pipe are arranged on that shell; a plurality of baffles are arranged in the first cooling cavity along the length direction of the shell; the cross section of the baffles is matched withthe cross section of the first cool cavity; and a plurality of opening grooves are arranged on the circumferential array on the outer peripheral surface of the baffles. When the coolant enters the first cooling chamber from the inlet pipe and flows toward the outlet pipe, the coolant can only flow out from the opening groove on the baffle plate, and the baffle plate can play a blocking role to reduce the flow rate of the coolant, and the coolant can take away more heat, thus improving the utilization rate of the coolant, reducing the energy consumption and avoiding waste.

Description

technical field [0001] The invention relates to a power generating device, in particular to a brushless generator. Background technique [0002] A brushless alternator is actually two generators, one as the exciter and one as the main generator. The field winding of the main generator is in the rotor, and the armature winding is in the stator (to generate electric output); the armature winding of the exciter is in the rotor, and the field winding is in the stator. The working principle of the brushless alternator is to provide excitation to the excitation winding of the exciter on the stator, and its rotor armature winding will generate alternating current, and after rectification, the rotor supplies power to the excitation winding of the main generator on the rotor, so that the main generator The machine induces the required alternating current in the armature winding of the stator. The heat dissipation efficiency of the existing brushless alternator is not high, which ca...
