Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 4, in the embodiment of the utility model, a cooling and heat dissipation structure for an electronic speed regulator comprises an electronic speed regulator shell 1 and a circuit board 5 positioned in the electronic speed regulator shell 1 and used for installing electronic components required by the electronic speed regulator, wherein a heat conduction silicone grease 4 attached to the lower surface of the circuit board 5 is arranged in the electronic speed regulator shell 1, so that heat generated by the circuit board 5 is guaranteed to be conducted onto the heat conduction silicone grease 4, the temperature of the circuit board 5 is reduced, a cold water pipeline 3 penetrates through the bottom of the electronic speed regulator shell 1 and is positioned below the heat conduction silicone grease 4, and cold water is introduced into the cold water pipeline 3 to enable the cold water pipeline 3 to exchange heat with the heat conduction silicone grease 4, thereby reducing the temperature of the heat conduction silicone grease 4 and improving the heat dissipation effect.

A water inlet end 301 and a water outlet end 302 are arranged at one end of the electronic speed regulator shell 1;

four plugs 2 are arranged on the electronic speed regulator shell 1;

specifically, as shown in fig. 2, the plug 2 adapted to the cold water pipeline 3 seals the cold water pipeline tightly, so that cold water circulates inside the electronic speed regulator housing 1, and no external hose is visible.

Specifically, as shown in fig. 3, the heat dissipation area of the cold water pipeline 3 is just under the circuit board, heat generated during operation of the circuit board 5 is covered on the heat conduction silicone grease 4, two ends of the cold water pipeline 3 are respectively provided with a water inlet end 301 and a water outlet end 302, cold water is introduced into the cold water pipeline 3 through the water inlet end 301, and after circulating heat dissipation, the cold water is discharged into the corresponding pipeline through the water outlet end 302. When cold water passes through the pipeline, the cold water can not pass through the outside of the shell and circulates only in the area below the circuit board, so that a large amount of heat emitted by the electronic speed regulator can be taken away more quickly, and a better heat dissipation effect is achieved.

Specifically, as shown in fig. 4, the cold water pipeline is composed of four transverse holes and two vertical holes in a staggered manner, and the cold water introduced circulates along a fixed unique path under the action of the plug 2.

The design of the application cancels the traditional quick connector and hose, plugs the pipeline outside the shell through the machine rice screw, seals the pipeline by using waterproof glue, circulates cold water inside the shell, and does not need to pass through the outside of the shell, thus saving the cost, improving the cooling efficiency and achieving better heat dissipation effect. When the electronic speed regulator works, the water inlet is required to be connected with the water pump, and when the water pump works, cold water flows through the cold water pipeline in the shell and then flows out of the water outlet, so that a large amount of heat emitted by the electronic speed regulator can be taken away.

The working principle of the utility model is as follows:

In summary, when the electronic speed regulator is used, the cold water outlet pipe is connected to the water inlet end 301, the cold water recovery pipe is connected to the water outlet end 302, the circuit board 5 inside the electronic speed regulator generates heat, the heat is directly led into the heat conduction silicone grease 4, after the cold water is connected, the cold water circularly flows in the cold water pipeline 3, heat exchange is performed between the cold water and the heat conduction silicone grease 4 through the cold water pipeline 3, the temperature of the heat conduction silicone grease 4 is reduced, and therefore the heat dissipation effect on the circuit board 5 is achieved.
