Description

Technical Field

[0001] The present application relates to the field of water pumps, and in particular to a mounting structure for a controller heat dissipation plate and a water pump applying the mounting mechanism. Background Art

[0002] A water pump is a machine for transporting liquids or increasing the pressure of liquids; it transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid, and is mainly used to transport liquids including water, oil, acid-base liquids, emulsions, suspension liquids, and liquid metals, etc. A controller is installed on the water pump to control the start-stop, speed, forward and reverse rotation, etc. of the motor inside the water pump; conventional controllers are placed above the motor or on one side of the motor, and a controller box is set to cover the controller to prevent water from leaking into the motor or onto the controller, thereby causing damage to the controller.

[0003] Currently, the common practice is to directly install the controller on the water pump motor. However, since there is no heat dissipation structure provided between the controller and the water pump, the heat at the contact part between the two cannot be quickly and effectively dissipated, which also affects the reliability of the controller and the water pump. Summary of the Utility Model

[0004] In order to improve the heat dissipation efficiency between the controller and the water pump and ensure the reliability of the water pump and the controller, the present application provides a mounting structure for a controller heat dissipation plate and a water pump applying the mounting mechanism.

[0005] In a first aspect, the present application provides a mounting structure for a controller heat dissipation plate, adopting the following technical solution:

One side of the bottom plate along the sliding direction of the bottom plate is for mounting the controller. The other side of the bottom plate is provided with a cavity, and the cavity penetrates the bottom plate along the width direction of the bottom plate. One end of the bottom plate far from the bottom of the cavity is connected to the outer periphery of the water pump motor.

[0007] By adopting the above technical solution, the bottom plate is provided. The bottom plate is connected to the outer periphery of the water pump motor, and the cavity is provided on the bottom plate and penetrates the bottom plate along the width direction of the bottom plate, so that a channel for air communication is left between the bottom plate and the water pump, improving the heat dissipation efficiency between the controller and the water pump and ensuring the reliability of the water pump and the controller.

[0008] Preferably, it further includes a snap ring and a contact plate. The snap ring is connected to the side of the bottom plate far from the bottom of the cavity, and the contact plate is connected to the side of the bottom plate close to the snap ring. A communication groove is provided on the side of the snap ring close to the contact plate, and the communication groove is for the rib on the outer periphery of the motor to pass through and be embedded in the snap ring. The surface of the contact plate close to the snap ring is for contacting the outer wall of the motor.

[0009] By adopting the above technical solution, the snap ring is used for the convex rib on the outer periphery of the motor to be embedded. Rotate the bottom plate so that the abutting plate abuts against the outer wall of the motor, making the outer wall of the convex rib abut against the inner wall of the static and dynamic snap ring, realizing the connection between the heat dissipation plate and the motor, and facilitating the installation and disassembly of the heat dissipation plate and the motor.
