Problems solved by technology

For the rare earth permanent magnet brushless motor, in addition to controlling the temperature of the motor pump body, the temperature of the controller must also be effectively controlled. According to the actual test data, it can be concluded that the local temperature of the controller is often higher than that of the motor body, and the excessive temperature Tends to cause irreversible damage to the on-board electronics within the controller

Embodiment 1

[0054] Such as figure 1 and 2As shown, a high-pressure cleaning device includes a spray gun unit and a motor pump unit. The motor pump unit 9 includes: a pump 7 , a brushless motor 5 , a controller 2 for controlling the brushless motor 5 , and a controller water cooling body 3 . The brushless motor 5 is a rare earth permanent magnet brushless motor. As a typical motor type, an NdFeB permanent magnet brushless motor can be selected. The pump 7 has a pump water inlet 11 and a pump water outlet 12, and the pump water outlet 12 is connected to the spray gun unit through a water pipe to realize water spraying and cleaning. The brushless motor 5 has an iron core 8 and a casing 4 , the casing 4 encloses the iron core 8 , especially its inner wall 405 clings to the iron core 8 to establish a heat conduction path. The controller 2 has a higher temperature surface 201, and the main high-power electronic components in the controller 2 are arranged close to the higher temperature surfac...

Embodiment 2

[0072] The difference from Embodiment 1 is that in this embodiment, the water-cooled body 3 of the controller is connected to the outer side of the housing 4 in the circumferential direction through a sealing member.

[0073] In the present invention, the side ribs 307, the first heat conducting ribs 307, the second heat conducting ribs 404, and the horizontal ribs not only serve as functional parts to realize heat conduction and external radiation, but also serve as structural parts to improve local strength.

Abstract

The invention discloses a water-cooling brushless motor pump unit and high-pressure cleaning equipment. The water-cooling brushless motor pump unit comprises a pump, a brushless motor, a controller and a controller water cooling body, wherein the pump is equipped with a water inlet and a water outlet; the brushless motor is connected with the pump and equipped with an iron core; the controller isused for controlling the brushless motor and equipped with a relatively-high-temperature surface; the controller water cooling body is equipped with a relatively-low-temperature surface; when the relatively-low-temperature surface and the relatively-high-temperature surface are in contact with each other, the controller water cooling body is equipped with a first water port and a cooling flow channel is formed by inward extending along the first water port; the brushless motor is further equipped with a shell; the shell is equipped with a ring-shaped cavity; the iron core is wrapped in the shell and the shell clings to the iron core; through the connection between the shell and the controller water cooling body, the ring-shaped cavity and the cooling flow channel communicate with each other so as to form a cold flow path; the ring-shaped cavity is equipped with a second water port and the second water port is formed outside the shell; and the second water port or the first water port is connected with the water inlet of the pump through a connecting pipe. The water-cooling brushless motor pump unit disclosed by the invention has the beneficial effects that the brushless motor and the controller can be separately cooled by utilizing cleaning water, the machine efficiency can be effectively improved, and the machine life can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a water-cooled brushless motor pump unit. Background technique [0002] High-pressure cleaning equipment is a kind of equipment that uses water or a mixed solution added with cleaning agent as the cleaning medium, and uses high-pressure water flow to clean the surface of the object. It is mainly composed of a spray gun unit and a motor pump unit. The spray gun unit is responsible for forming different shapes according to actual needs. water flow, while the motor-pump unit delivers the water from the municipal water mains to the spray gun unit. [0003] The motor pump usually includes a motor and a pump, and the pump can work normally under the drive of the motor to realize water delivery. As an electrical device, the motor also generates a large amount of heat energy while converting electrical energy into mechanical energy, thereby increasing the operatin...
