Abstract

The invention discloses an externally-closed heat-radiating system of a motor, belonging to the field of motor industries. The externally-closed heat-radiating system of the motor comprises a base, a stator, a rotor, a front end cover, a back end cover, a fan housing, an air pipe, an air blower and a base air hole. The externally-closed heat-radiating system is characterized in that the base, the stator, the rotor, the front end cover and the back end cover form the motor body. The fan housing is pressure-tight and is clamped on the base, and an air intake arranged on the fan housing is connected with the air pipe. The base air hole is formed by the base, a heat dissipation rib and a welding board, one end of the base air hole is connected with atmosphere, and the other end of the base air hole is connected with an inner cavity of the fan housing. One end of the air pipe is connected with the air blower, and the other end of the air pipe is connected with the fan housing. In the invention, through measures of increasing cooling air flow, enlarging heat dissipation area, improving cooling air efficiency and the like, the effect of reducing temperature rise is achieved. The invention can be used in the industry such as car motors, compact type motors and the like with high power density requirements.

Description

The outside closed cooling system of motor
Technical field
The invention belongs to Mechanical Driven equipment motor technology field, specifically is the outside closed cooling system of a kind of brand-new motor.
Background technology
For the motor as Mechanical Driven equipment, the temperature rise of motor is an important examination project always.The field of employment of motor, load state and the performance requirement of self are all very big to the temperature rise influence.And under some situation, only rely on the heat-sinking capability of motor self, the heat that can not effectively shed, thereby cause electric machine temperature rise too high, electrical machine insulation damages, the lost of life, even burn.
Summary of the invention
The object of the invention provides the outside closed cooling system of a kind of brand-new motor.By increasing measures such as cooling air flow, increasing area of dissipation, raising cooling air efficient, played the effect that reduces temperature rise.
The technical solution used in the present invention is as follows:
The outside closed cooling system of a kind of motor, include support, stator, rotor, front end housing, rear end cap, fan housing, ventilation duct, air blast, the support ventilation hole, described support, stator, rotor, front end housing, rear end cap is formed motor body, it is characterized in that: described fan housing is airtight, be installed on the support, cover on outside the motor body, having an air inlet on the described fan housing links to each other with ventilation duct, described base outer has ventilation hole, described support ventilation hole one end links to each other with atmosphere, the other end links to each other with the fan housing inner chamber, and described ventilation duct one end links to each other with air blast, and the other end links to each other with fan housing.
The outside closed cooling system of described motor, it is characterized in that: described air inlet place does not have Inlet Network.
The outside closed cooling system of described motor, it is characterized in that: described ventilation hole outer surface evenly is welded with radiating ribs, the welded plate of burn-oning again on radiating ribs then.
Useful effect
The outside closed cooling system of this motor, at first, the internal heat ventilation circulation system of forming by support, stator, rotor, front end housing, rear end cap, the heat that motor is produced passes on the support shell, be delivered on the radiating ribs and welded plate of forming the support ventilation hole by heat conduction again, radiating ribs and welded plate can both play conduction of heat, compare with traditional support and have just strengthened area of dissipation.Secondly, the a large amount of cooling air that blows out by air blast, enter in the fan housing through ventilation duct, and then in fan housing blows to the support air duct, this cooling wind energy is taken away the heat on radiating ribs and the welded plate rapidly, and the temperature of radiating ribs is descended, and so just can accelerate the speed of support shell to radiating ribs and welded plate conduction heat, the heat that motor is produced quickens to distribute, and makes electric machine temperature rise descend.The 3rd, this cooling system be by the outside independently air blast cooling air is provided, the air quantity of cooling air just is guaranteed.By checking, the outside closed cooling system good heat dissipation effect of this motor makes electric machine temperature rise be controlled effectively, and electrical machinery life is secure.
Description of drawings
Fig. 1 is the structural representation of the outside closed cooling system of this motor.
Embodiment
The outside closed cooling system of motor, include support 5, stator 6, rotor 8, front end housing 7, rear end cap 4, fan housing 3, ventilation duct 2, air blast 1, the support ventilation hole, described support 5, stator 6, rotor 8, front end housing 7, rear end cap 4 is formed motor body, fan housing 3 is airtight, be installed on the support 5, cover on outside the motor body, having an air inlet on the described fan housing 3 links to each other with ventilation duct 2, there is ventilation hole described support 5 outsides, described support ventilation hole one end links to each other with atmosphere, the other end links to each other with fan housing 3 inner chambers, and described ventilation duct 2 one ends link to each other with air blast 1, and the other end links to each other with fan housing 3.The ventilation hole outer surface evenly is welded with radiating ribs, the welded plate of burn-oning again on radiating ribs then.
