Embodiment Construction
[0016] Such as figure 1 As shown, a specific embodiment of the present invention includes a housing 1, a circuit board, a cover 2, a water tank 3, a water pump 4 and a temperature switch.
[0017] The outer side of the housing 1 is spirally provided with a guide tube 11. The guide tube 11 is an integral structure with the housing 1. It protrudes from the housing 1. It is hollow inside and has openings at both ends. The water pump The input end of 4 is connected with water tank 3, and the output end is communicated with one end opening of described guide tube 11, and the other end opening of guide tube 11 is communicated with water tank 3, and water enters guide tube 11 through water pump 4 from water tank 3, and then Flow into the water tank 3 from the other end opening of the draft pipe 11 .
[0018] The temperature switch is connected in series in the power circuit of the water pump 4, the temperature switch is a normally open switch, the temperature switch is located insid...

A controller of an electric vehicle comprises a casing, a circuit board, a cover body, a water tank, a water pump and a temperature switch, wherein a diversion pipe is spirally arranged on the outside of the casing; an input end of the water pump is connected with the water tank, and an output end of the water pump is communicated with one end of the diversion pipe; the other end of the diversion pipe is communicated with the water tank; the temperature switch is connected in a power supply circuit in series and located inside the casing; an opening is formed in one end of the casing, and a threaded hole used for connecting the cover body is formed in the opening; circuit board insertion slots are formed in two sides of the inside of the casing; a wire outlet hole is formed in the casing. The controller of the electric vehicle adopts water cooling, so that the cooling effect is improved greatly; the temperature switch is arranged in the controller, so that water can circulate automatically for cooling. The circuit board insertion slots are formed in the casing of the controller, so that the controller is not only convenient but also stable, and the shake-proof effect is good; waterproof sponge is arranged at the opening of the cover body, so that water can be prevented from entering the controller.
Description
technical field [0001] The invention relates to an electric vehicle controller used on an electric vehicle. Background technique [0002] The electric vehicle controller is one of the cores of electric vehicle control, and it needs to have good waterproof, shockproof and heat dissipation performance. If the seal is not good, water entering the electric vehicle controller will cause a short circuit on the circuit board. During cycling, the frequent vibration of the circuit board will also damage the components on the circuit board. For the heat dissipation of the controller, the current method is mainly to use an aluminum shell, and then set a heat sink on the outside of the shell. It will affect the service life of the controller, or even burn out the circuit board. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a controller for an electric vehicle with good hea...
