Embodiment Construction

[0009] like figure 1 As shown, a double-layer structure vertical motor cooling device, the cooling device 7 is an integral structure, composed of a fan 1 and an air-water cooler 2, the fan 1 and the air-water cooler 2 are located on the inner panel of the double-layer structure vertical motor 5 and the outer plate 4, the fan 1 and the stator core 6 are in the same horizontal plane, the outer plate 4 is in contact with the stator core 6, the air-water cooler 2 is fixed on the outer side of the outer plate 4 by bolts, and the fan 1 passes through the inner plate and passes through the bolts Fixed on the outside of the air-water cooler 2.

[0010] The cooling device 7 is composed of the fan 1 and the air-water cooler 2 connected to each other in the horizontal direction to form an overall structure. The fan 1 has two sets of independent fan blades, and the blowing direction is vertically upward and vertically downward respectively. The air-water cooler 2 There is a separate wate...

Abstract

The invention relates to a cooling device for a vertical motor of a double-layer structure. The cooling device (7) is of an integral structure and is composed of a draught fan (1) and an air-water cooler (2). The draught fan (1) and the air-water cooler (2) are located between an inner side plate (5) and an outer side plate (4) of the vertical motor of the double-layer structure, and the draught fan (1) and a stator core (6) are located on the same horizontal plane. The outer side plate (4) is in contact with the stator core (6), and the air-water cooler (2) is fixed to the outer side of the outer side plate (4) through a bolt. The draught fan (1) penetrates through the inner side plate and then is fixed to the outer side of the air-water cooler (2) through a bolt. The cooling device solves the problem that a traditional cooling device cannot be used for the vertical motor of the double-layer structure, the key parts, namely the draught fan and the air-water cooler of the whole cooling device are of an integrated structure and are installed between the inner side plate and the outer side plate of the motor, and the size of the motor is not increased. A motor cooling medium in the whole cooling device is air, the air circulates independently in the motor and does not exchange with external air, and the protection performance of the motor is good.

Description

technical field [0001] The invention relates to a double-layer structure vertical motor cooling device. Background technique [0002] At present, for some vertical motors used in high-temperature environments, the side plates of the frame adopt a double-layer structure, and the distance between the inner plate and the outer plate is relatively large, which can isolate the high temperature of the environment to the outside, and effectively avoid the influence of the high temperature environment on the motor winding and iron core. , Protect the motor and prolong the service life of the motor. However, due to the double-layer structure of the motor, the side plate of the motor is divided into an inner plate and an outer plate. The cooling device of a vertical motor with a traditional structure is generally installed directly on the side plate. After the hot air in the motor room enters the cooling device through the side plate, the hot air directly and Ambient air exchange to ...
