[0002] The loop-type heat dissipation water channel of the motor controller housing is a design that realizes heat dissipation through water circulation. In the design of the motor controller housing, a water channel system is usually set up, and water will circulate in the system. Through the heat conductivity of water, the heat generated inside the controller is taken away, so as to achieve the effect of heat dissipation. This loop-type heat dissipation water channel design can effectively take out the internal heat and ensure the normal operation and stability of the motor controller.

[0003] At present, the heat dissipation water channel designs for power devices are mostly formed by casting. To form samples or for initial testing, mold opening is required for casting, and the mold opening cost is very high. At the same time, the mold opening time is relatively long, which will delay the early development and the formation of samples. Moreover, after the casting mold is finalized, it cannot be changed, making it impossible to further adjust the insufficient heat dissipation. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The utility model provides a loop - type heat - dissipation water channel of the housing of a motor controller as shown in Figures 1-5 which includes a housing main body 1. Inside the housing main body 1, a loop - type heat - dissipation water channel main body 2 for heat dissipation is installed. The loop - type heat - dissipation water channel main body 2 allows water to flow through the water inlet 3 and the water outlet 4 at the front end. At the upper end of the loop - type heat - dissipation water channel main body 2, a water channel cover plate 12 is provided. At the front end of the housing main body 1, a protective frame 6 is installed at the internal position. The fixed plates 7 at the left and right sides of the front end of the protective frame 6 are attached to the front end of the housing main body 1. The elastic buckles 10 at the four corners of the rear end of the protective frame 6 are clamped to the inner wall of the housing main body 1. At the outer position inside the protective frame 6, a protective filter screen 5 is provided. Inside the protective filter screen 5, a coarse filter screen 11 is provided. Inside the coarse filter screen 11, a fine filter screen 8 for isolating fine particles is provided.

[0024] The loop-type heat dissipation water channel sends water into the interior of the loop-type heat dissipation water channel main body 2 through a water pump device. When the electronic components generate heat inside the housing main body 1, the surrounding temperature rises. At this time, the water flows through the loop-type heat dissipation water channel around the heat source and absorbs the heat released by it. The water pump transports the water that has absorbed heat to an external location, and then transports new cooling water to the interior, continuously circulating to perform the heat dissipation function. This process repeats continuously to keep the internal temperature of the device within the normal range.

[0025] As Figure 2 and Figure 4 shown, a reserved groove 9 is provided at the outer end face position of the housing main body 1. The housing main body 1 is installed with a motor through the mounting holes at the four upper corners. The loop-type heat dissipation water channel main body 2 is installed with the housing main body 1 through bolts. The water inlet 3 and the water outlet 4 enable water to flow inside the loop-type heat dissipation water channel main body 2. The protective frame 6 is installed with the housing main body 1 through elastic buckles 10 and fixing plates 7. When the elastic buckles 10 are clamped at the inner wall position of the housing main body 1, the fixing plates 7 are closely attached to the front end of the housing main body 1. The protective filter screen 5 can prevent large particles and foreign objects from entering the interior of the housing main body 1. The coarse filter screen 11 increases the structural stability of the protective filter screen 5 and the fine filter screen 8. The fine filter screen 8 blocks fine particulate matter.

[0026] A heat dissipation hole is provided at the front end position of the housing main body 1. The heat dissipation hole is composed of a protective filter screen 5, a coarse filter screen 11, and a fine filter screen 8. The protective filter screen 5 can effectively prevent large particle debris from entering the interior of the housing. The middle coarse filter screen 11 and the fine filter screen 8 can further filter impurities in the air. The main function of the fine filter screen 8 is to filter fine dust particles and microparticles to ensure that they do not enter the internal components. The protective frame 6 is installed and disassembled with the housing main body 1 through elastic buckles 10. After being used for a period of time, it can be disassembled to clean the filter screen, which does not affect the heat dissipation effect.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
