DETAILED DESCRIPTION

[0027] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0028] The first implementation method:

[0029] Figure 1-9 A high-voltage motor with a cooling circulation system is shown, comprising a body 1 and a cooling circulation pump 2, a plurality of cooling plates 3 are fixedly connected to the outer wall of the body 1, the plurality of cooling plates 3 are fixedly connected, the input end and the output end of the cooling circulation pump 2 are respectively fixedly connected to connecting pipes 4 between two cooling plates 3, the two cooling plates 3 connected to the two connecting pipes 4 are adjacent, through holes 5 are opened between the plurality of cooling plates 3, and a heat sink 6 is fixedly connected to one end of the cooling plate 3;

[0030] The side walls of the machine body 1 close to the multiple cooling plates 3 are fixedly connected with auxiliary heat dissipation devices, and the auxiliary heat dissipation devices include two inner plates 7 fixedly connected to the side walls of the machine body 1, multiple middle rods 701 and multiple outer rods 702, the middle rod 701 is located on the outside of the inner plate 7, the outer rod 702 is located on the outside of the middle rod 701, a slide plate 703 is slidably connected between the two inner plates 7, the middle part of the slide plate 703 is rotatably connected with a rotating shaft 704, both ends of the rotating shaft 704 are respectively fixedly connected with a cooling fan 705 and a right opposite plate 706, the cooling fan 705 is located on one side of one end of the heat sink 6, a support ring 707 is fixedly connected between the multiple middle rods 701, the inner wall of the support ring 707 is rotatably connected with a rotating circle 708, the side wall of the rotating circle 708 is fixedly connected with a traverse rod 709, the inner wall of the rotating circle 708 is fixedly connected with multiple inner rods 710, and multiple A center rod 711 is fixedly connected between the inner rods 710, one end of the center rod 711 is fixedly connected to a left pair of plates 712, and the left pair of plates 712 is located on one side of the right pair of plates 706, an outer plate 713 is fixedly connected between one end of the plurality of outer rods 702, a moving shaft 714 and a fixed shaft 715 are rotatably connected to the side wall of the outer plate 713, one end of the moving shaft 714 and the fixed shaft 715 are both fixedly connected to a rotating wheel 716, a transmission belt 717 is rotatably connected between the two rotating wheels 716, a vertical rod 718 is fixedly connected to the outer wall of the transmission belt 717, the vertical rod 718 is transmission-connected to the transverse rod 709, a driven gear 719 is fixedly connected to the outer wall of the fixed shaft 715, and the auxiliary heat dissipation device also includes an electric rod 720 fixedly connected to the side wall of the body 1, and the telescopic end of the electric rod 720 is transmission-connected to the slide plate 703;

[0031] A central driver is fixedly connected to the middle of the side wall of the body 1, and the central driver includes a motor 8. A plurality of struts 801 are fixedly connected to the outer wall of the motor 8. A gear ring 802 is fixedly connected between one ends of the plurality of struts 801, and the gear ring 802 is meshed with the driven gear 719.

[0032] When in use, the heat dissipation liquid circulates between the cooling circulation pump 2 and the multiple cooling plates 3. The heat dissipation liquid is cooled in the body 1. The heat dissipation liquid takes away the heat generated by the body 1 in the cooling plates 3. At the same time, the heat sink 6 can assist the cooling plates 3 in dissipating heat.

[0033] The motor 8 can drive the ring gear 802 to rotate. When the ring gear 802 rotates, it drives the transmission belt 717 to rotate through the driven gear 719. When the transmission belt 717 rotates, it drives the vertical rod 718 to rotate. When the vertical rod 718 rotates, it contacts the horizontal rod 709 and drives the rotating circle 708 to rotate. When the rotating circle 708 rotates, it drives the left opposite plate 712 to rotate.

[0034] When the temperature of the machine body 1 at a certain place is too high, the temperature of the cooling plate 3 at the corresponding position increases, and the temperature radiated outward by the heat sink 6 increases. At this time, the electric rod 720 is started to extend and drive the slide plate 703 to move toward the left pair of plates 712 until the right pair of plates 706 and the left pair of plates 712 contact. At this time, the cooling fan 705 rotates to dissipate heat from the cooling plate 3.

[0035] By setting up the central driver and the auxiliary heat dissipation device, the location of the body 1 with excessively high temperature can be specifically cooled during operation, preventing the water flow from affecting subsequent heat dissipation when passing through the location of the body 1 with excessively high temperature, thereby improving the overall heat dissipation effect.

[0036] The second implementation method:

[0037] Figure 3-9 A high-voltage electric motor with a cooling circulation system is shown. Different from the first embodiment, a pull rod 721 is fixedly connected to one end of the electric rod 720, and an elastic rope 722 is fixedly connected between one end of the pull rod 721 and the slide plate 703. Through the above arrangement, when the electric rod 720 moves to the left, the slide plate 703 can be driven to move to the left through the pull rod 721 and the elastic rope 722 until the left pair of plates 712 and the right pair of plates 706 are in contact. After the left pair of plates 712 and the right pair of plates 706 are in contact, the electric rod 720 can continue to move to the left, and the elastic rope 722 is stretched.

[0038] A base 723 is arranged between one end of the moving coupling shaft 714 and the outer plate 713, one end of the base 723 is slidably connected with a movable seat 724, one end of the moving coupling shaft 714 is rotatably connected with the movable seat 724, two cross arms 725 are fixedly connected to the side wall of the outer plate 713, a long gear 726 is rotatably connected between the two cross arms 725, one end of the electric rod 720 is fixedly connected with a push-pull rack 727, the push-pull rack 727 and the cross arm 725 are both engaged with the long gear 726, the transmission belt 717 is composed of a variable distance belt 71701 and a fixed distance belt 71702, the variable distance belt 71701 is set to an elastic material, the variable distance belt 71701 is set to a non-elastic material, and the vertical moving rod 718 and the fixed distance belt 71702 are fixedly connected.

[0039] When the cooling fan 705 starts to dissipate heat for the heat sink 6, but the temperature of the heat sink 6 does not drop, the telescopic end of the electric rod 720 continues to move to the left, and drives the push-pull rack 727 to move to the left. At this time, the long gear 726 rotates to drive the cross arm 725 to move to the right, so that the moving shaft 714 moves toward the direction of the fixed shaft 715, and the distance between the two rotating wheels 716 is shortened, and the length of the transmission belt 717 is shortened. When the rotation speed of the driven gear 719 remains unchanged, the rotation speed of the transmission belt 717 is increased. When the rotation speed of the transmission belt 717 is increased, the rotation of the circle 708 is increased, the rotation speed of the cooling fan 705 is increased, and the heat dissipation effect on the heat sink 6 is improved.

[0040] Through the above arrangement, the auxiliary heat dissipation device can provide a better heat dissipation effect for the position of the body 1 where the temperature is too high, thereby further improving the overall heat dissipation effect of the body 1.

[0041] The auxiliary heat dissipation device also includes a temperature sensor 728 fixedly connected to the side wall of the body 1. The temperature sensor 728 is located on the side wall of the heat sink 6. The temperature sensor 728 and the electric rod 720 are electrically connected. Through the above setting, the temperature sensor 728 can detect the temperature of the heat sink 6 and control the extension and retraction of the electric rod 720.

[0042] The surfaces of the right pair of plates 706 and the left pair of plates 712 that are close to each other are both set to rough surfaces. Through the above settings, the friction between the right pair of plates 706 and the left pair of plates 712 can be increased, so that the transmission between the right pair of plates 706 and the left pair of plates 712 can be better.

[0043] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
