Hollow cooler for motor

Abstract

The invention relates to a cooler for an electric motor, in particular to an air-to-air cooler for the electric motor, and solves the problem that capacity of the electric motor is limited by temperature rise level because the prior air-to-air cooler with a defective structure can not fully cool the electric motor. The air-to-air cooler comprises a cooler shell, evenly distributed air ducts are fixed in the cooler shell, a diaphragm plate positioned at the upper part of each air duct is fixed in the cooler shell, the diaphragm plate is provided with an air inlet and an air outlet relative to positions of an air inlet and an air outlet at the bottom of the cooler shell, the inner wall of a top slab of the cooler shell is fixed with a draught fan positioned at the upper part of the air inlet of the diaphragm plate, and an inner air deflector and an outer air deflector are also fixed in the cooler shell. Through the draught fan, the diaphragm plate and the air deflectors arranged in the air-to-air cooler, the air-to-air cooler fully sucks hot air inside the electric motor into the cooler, enhances circulation of hot air in the electric motor, substantially reduces temperature rise of the electric motor, and overcomes limit of the temperature rise of the electric motor on the capacity of a generator.

Description

technical field [0001] The invention relates to a cooler for a motor, in particular to an air-to-air cooler for a motor. Background technique [0002] In order to fully reduce the temperature rise of the motor (such as a wind turbine), an air-to-air cooler is fixed on the top of the motor (such as the attached figure 1 shown). The existing air-to-air cooler includes a cooler shell, the bottom of the cooler shell has an air inlet and air outlets located on both sides of the air inlet; uniformly distributed air ducts are fixed in the cooler shell, and one end of the cooler shell A fan is fixed, and the other end of the cooler is a horizontal air outlet. On the inner wall of the bottom surface of the cooler shell between the air inlet and the air outlet, a partition plate with an air guide pipe crossing it is fixed. Equal height (that is, there is a gap between the top of the partition plate and the top plate of the cooler housing), which is used to isolate the air inlet and ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the existing air-to-air cooler cannot fully cool down the motor due to structural defects, and thus the capacity of the motor is limited by the temperature rise level, the present invention provides an air-to-air cooler for a motor with an improved structure that can fully cool down the motor
