The technical scheme of the utility model is specifically described below with reference to the accompanying drawings.
Example 1:
the embodiment provides a water-cooling heat dissipation structure for a two-wheeled electric vehicle, which comprises a guide pipe 1 and a cooling box, as shown in fig. 1, wherein the cooling box is positioned at the outer side of a motor and can be connected with a corresponding pipeline in the motor through the guide pipe 1, so that the circulating flow of liquid flow is realized, and the good heat dissipation effect of the motor is ensured.
Specifically, the cooling tank comprises a tank body 2, a liquid storage tank 3, a water pump 4 and a heat exchange assembly 5 are arranged in the tank body 2, and as shown in fig. 2, cooling liquid flowing into the tank body 2 through the guide pipe 1 can sequentially flow through the liquid storage tank 3 and the heat exchange assembly 5 under the action of the water pump 4.
The motor load can be effectively reduced by arranging the box body 2 loaded with the cooling liquid outside the motor, and meanwhile, the cooling liquid can be connected with the motor through the conveying of the guide pipe 1 to ensure that the heat dissipation effect of the water cooling equipment is not influenced.
Specifically, the case 2 has a hollow structure, and a hole is formed in a sidewall of the case, through which the conduit 1 can be connected to a related structure located in the case 2.
As an alternative embodiment, the heat exchange assembly 5 includes a heat pipe 51 and a liquid-cooled circulation plate 52; wherein the liquid cooling circulation plate 52 is fixedly provided in the case 2, one side surface portion of which is recessed and forms a flow passage 521 for placing the heat conductive pipe 51; one end of the heat conducting pipe 51 is connected with the liquid storage tank 3, the other end is connected with the guide pipe 1 through the tank body 2, and the middle part of the heat conducting pipe 51 can be embedded on the surface of the liquid cooling circulation plate 52 through the flow passage 521.

In order to ensure a better heat dissipation rate at the bump 522, in this embodiment, the heat exchange assembly 5 further includes a heat dissipation silica gel layer 53, where the heat dissipation silica gel layer 53 is located between the tank 2 and the liquid cooling circulation plate 52.
Specifically, the heat dissipating silicone layer 53 can cover at least a portion of the bumps 522.
The heat dissipation silica gel has better softness, and when the heat dissipation silica gel is matched with the convex blocks 522, the protection of the liquid cooling circulation plate 52 can be realized, the liquid cooling circulation plate 52 is prevented from being damaged due to larger pressure, and meanwhile, the contact area between the heat dissipation silica gel layer 53 and the liquid cooling circulation plate 52 can be increased, so that the heat dissipation silica gel layer 53 and the liquid cooling circulation plate 52 are fully contacted, and therefore the heat conduction efficiency is effectively improved.
Because the viscosity of heat dissipation silica gel itself is relatively poor, in order to conveniently fix above-mentioned heat dissipation silica gel and liquid cooling circulation board 52, avoid equipment to appear the displacement when using and damage even, in this embodiment, set up the device and still include tie coat 54, above-mentioned heat dissipation silica gel layer 53 can be fixed on the inside wall of box 2 through tie coat 54.
Further, a heat dissipation hole 22 is provided on the side of the case 2 attached to the heat exchange assembly 5. This structure can be used to allow the heat in the tank 2 to be dissipated as quickly as possible.

The number of the mounting brackets 21 may be two, and the two mounting brackets 21 are located on the same side of the case 2, and the gap between the two mounting brackets can be just used for inserting the liquid cooling circulation plate 52; or as shown in fig. 5, the number of the mounting brackets 21 is four at this time and the four mounting brackets 21 are symmetrically arranged at opposite sides of the case 2, and the liquid cooling circulation plate 52 is inserted and fixed at the corresponding position of the case 2 through a gap formed between the two mounting brackets 21.
It should be noted that the liquid storage tank 3 and the water pump 4 are located on one side of the liquid cooling circulation plate 52, and the heat dissipation silica gel and the adhesive layer 54 are located on the other side of the liquid cooling circulation plate 52.
In order to realize the circulation flow of the liquid, as an alternative embodiment, a liquid inlet pipe 55 and a liquid outlet pipe 56 which are connected with the conduit 1 through the box body 2 are also arranged in the box body 2; the other end of the liquid inlet pipe 55 is connected with the water pump 4, and the other end of the liquid outlet pipe 56 is connected with the heat exchange assembly 5.
When the device is connected with motor equipment, the structure of the device is shown in fig. 6, and the conduit 1 can be connected with a motor stator and perform heat dissipation treatment on the stator.
The structure of the stator and the distribution position of the guide pipes on the stator are the prior art, and are not described herein.
When the motor works, the higher the load is, the more energy is required to be consumed, the more current is required, and the higher the heating value is. As the heating value of the motor increases, the higher the temperature at the motor starts to increase, and the corresponding energy loss increases. In order to improve the working efficiency of the motor as much as possible, the motor can be subjected to water cooling heat dissipation treatment. Through with external water-cooling equipment in this scheme, can effectively alleviate the motor load under the prerequisite that does not influence the motor radiating effect to reduce the heat dissipation capacity of motor, help improving the work efficiency of motor.
The working efficiency of the conventional motor is about 87%, but the working efficiency of the motor with the water cooling structure in this embodiment can be improved to 91%.
Under the condition that other structures are unchanged, the working efficiency of the motor with the external water-cooling heat dissipation structure is higher. When the device is installed on an electric vehicle, the device can effectively help to prolong the endurance mileage of the whole vehicle.
Example 2:
the utility model also provides a long-endurance electric vehicle, which comprises the water-cooling heat dissipation structure for the two-wheeled electric vehicle.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
