[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the following will provide a detailed description of the anti-scalding cover back-hanging device and the anti-scalding power conversion device of this utility model, in conjunction with the accompanying drawings and specific embodiments.

[0028] This utility model provides a back-hanging device for a heat-resistant cover of a power conversion equipment. The back-hanging device is used to hang and fix the power conversion equipment to prevent the skin from directly contacting the heating part of the power conversion equipment, thereby providing heat insulation and heat protection.

[0029] The power conversion equipment can be an inverter, converter, or rectifier, etc. In this embodiment, the power equipment is an inverter.

[0030] Combination Figure 1 As shown, the heat-proof cover back-hanging device for power conversion equipment of this utility model includes a heat-proof back plate 10 and a cover plate 20. The heat-proof back plate 10 serves to fix the device, and the cover plate 20 serves to shield it.

[0031] The heat-resistant back panel 10 includes a fixing plate 110 and a spacer plate 120. The fixing plate 110 is used to adhere to and contact the building, such as a wall. The spacer plate 120 is fixed to the two side edges of the fixing plate 110, in combination with... Figure 1 As shown, the two partition plates 120 are arranged symmetrically on the axis. The partition plates 120 are perpendicular to the surface of the fixed plate 110. The two partition plates 120 are fixed to the left and right edges of the fixed plate 110 to form a "U"-shaped groove structure.

[0032] The fixed plate 110 and the two partition plates 120 can be formed by sheet metal bending or fixed by welding.

[0033] One end of the anti-scalding back panel 10 is provided with a hanging hook 101, and the other end is provided with a fixing position 102; Figure 1 The central mounting hook 101 is located at the upper end of the anti-scalding back panel 10, and the fixing position 102 is located at the lower end of the anti-scalding back panel 10.

[0034] A back-hanging strip 320 is provided on the back of the power conversion device 30 (the side facing the heat-resistant back plate 10). The back-hanging strip 320 can be fixed to the back of the power conversion device 30 by bolts or by welding or other methods. Specifically, the back-hanging strip 320 can be fixed in the area where the heat sink 310 is located, and a clearance space is provided at the heat sink 310 to avoid the back-hanging strip 320.

[0035] The anti-scalding back panel 10 is equipped with a hanging hook 101 for hooking the back hanging strip 320 of the power conversion equipment 30. The hanging hook 101 and the back hanging strip 320 hook and cooperate with each other, mainly bearing the weight of the power conversion equipment 30.

[0036] The fixing position 102 of the anti-scalding back panel 10 is used to fix the power conversion device 30, limit the position of the power conversion device 30, and fix the power conversion device 30 on the anti-scalding back panel 10.

[0037] The cover plate 20 is located at the upper end of the anti-scalding back plate 10. The anti-scalding back plate 10 and the cover plate 20 work together to cover the heating part of the power conversion device 30. The cover plate 20 is fixedly mounted on the anti-scalding back plate 10 or the power conversion device 30. The mounting position of the cover plate 20 can be set on the anti-scalding back plate 10 or on the power conversion device 30.

[0038] When installing the power conversion device 30, first hang the back hanging strip 320 of the power conversion device 30 on the mounting hook 101. The mounting hook 101 bears the weight of the power conversion device 30, fixing the power conversion device 30 in the fixing position 102. After the power conversion device 30 is installed, the partition plate 120 abuts against the back of the power conversion device 30, so that the heat sink 310 on the back of the power conversion device 30 is located between the two partition plates 120. The heat sink 310 is a finned structure set on the back of the power conversion device 30, and the power conversion device 30 dissipates heat outward through the heat sink 310. After the power conversion device 30 is installed, the heat sink 310 is located between the two partition plates 120. The size of the heat sink 310 protruding from the back of the power conversion device 30 is smaller than the distance of the partition plate 120 protruding from the fixing plate 110. The heat sink 310 is located in the space between the two partition plates 120. Two partition plates 120 cover the heat sink 310 from the left and right sides respectively, and the cover plate 20 covers the heat sink 310 from above to prevent operators from being burned by direct contact with the heat sink 310.

[0039] Based on the above solution, the shapes of the anti-scalding back panel 10 and the cover panel 20 of this utility model are matched with the shape of the power conversion device 30. When the power conversion device 30 is installed in place, the outer edge formed by splicing the anti-scalding back panel 10 and the cover panel 20 is flush with the outer edge of the power conversion device 30, resulting in a smoother appearance.

[0040] Before installing the power conversion device 30, first fix the anti-scalding back panel 10 to the wall, then hook and secure the power conversion device 30, and finally install the cover plate 20. Since the power conversion device 30 needs to be moved downwards when hooked, the cover plate 20 needs to be removed before hanging the device to avoid interference. After the power conversion device 30 is hung and lowered, the cover plate 20 should be flush with the upper edge of the power conversion device 30 after it is secured.

[0041] In one specific embodiment, combined with Figure 1 As shown, the mounting hook 101 is set at the upper end of the fixing plate 110. The position of the mounting hook 101 is lower than the upper edge of the two partition plates 120, avoiding the cover plate 20, so as to ensure that the cover plate 20 is flush with the power conversion equipment 30 after it is fixed.

[0042] The mounting hook 101 is formed by bending the sheet metal of the upper edge of the fixing plate 110. The upper edge of the mounting hook 101 is an inclined slope that is inclined towards the power conversion equipment 30 to facilitate the insertion of the back hanging strip 320.

[0043] The fixing position 102 is set at the lower end of the partition plate 120, combined with Figure 1 , Figure 2 As shown, the fixing position 102 is a bent plate located at the lower end of the partition plate 120. The fixing position 102 is located at the lower edge of the partition plate 120, and each partition plate 120 is bent to form the fixing position 102. A fixing ear plate 330 is provided on the lower part of the back of the power conversion device 30. The fixing ear plate 330 can be pressed against the upper surface of the partition plate 120 and formed a relatively fixed assembly by bolts.

[0044] In addition, the fixing position 102 can also be made by bending the lower end of the fixing plate 110.

[0045] Combination Figure 1 As shown, the fixing plate 110 has several gourd-shaped holes 111 and several fixing holes 112. The gourd-shaped holes 111 have a structure that is narrow at the top and wide at the bottom. When fixing the fixing plate 110 to the wall, it is first hung on the wall nail through the gourd-shaped holes 111. The wide bottom structure of the gourd-shaped holes 111 makes it easier to insert the nail. When hanging, the fixing plate 110 moves downward and the nail enters the narrow top part of the gourd-shaped holes 111, forming a limiting fit for the nail.

[0046] The fixing holes 112 are arranged in an array on the fixing plate 110. The fixing holes 112 can have different shapes, such as oblong holes or round holes. After the fixing plate 110 is hooked through the gourd hole 111, several fixing pins or screws are inserted into the fixing holes 112 to further enhance the fixing effect.

[0047] Combination Figure 1 , Figure 2As shown, a wall-end cable outlet notch 113 is provided at the lower end of the fixing plate 110. The cable outlet notch 113 is a channel structure provided at the lower part of the fixing plate 110, and the cable led out from the power conversion equipment 30 can pass through the cable outlet notch 113.

[0048] Combination Figure 1 , Figure 2 As shown, several side ventilation holes 121 are provided on the partition plate 120 to facilitate ventilation and heat dissipation from the side. The side ventilation holes 121 penetrate the surface of the partition plate 120 and are distributed in an array.

[0049] Combination Figure 1 As shown, several upper ventilation holes 201 are provided on the cover plate 20 to facilitate ventilation and heat dissipation from above. The upper ventilation holes 201 penetrate the surface of the cover plate 20 and are distributed in an array. The shapes of the side ventilation holes 121 and the upper ventilation holes 201 are not limited.

[0050] Combination Figure 1 As shown, the cover plate 20 is fixed to the power conversion device 30 by the upper fixing bolt 202. A connecting ear plate is installed on the back of the power conversion device 30. The fixing bolt 202 passes through the cover plate 20 and is screwed onto the connecting ear plate on the back of the power conversion device 30.

[0051] This utility model also provides a heat-resistant power conversion device, including a power conversion device 30 and the aforementioned heat-resistant cover back-hanging device for the power conversion device, which can play a role in heat insulation and heat prevention, expand the installation location of the power conversion device, and expand the installation and use scenarios of the power conversion device.

[0052] This utility model of a heat-proof cover back-hanging device for power conversion equipment integrates two functions: heat protection and back-hanging. The left and right side partitions 120 have side ventilation holes 121 for air intake of the heat sink, and the top cover 20 has top ventilation holes 201 for air exhaust of the heat sink.

[0053] The anti-scalding back panel 10 has a gourd-shaped hole 111 on the back for easy hanging, and a fixing hole 112 is reserved for wooden and sandstone walls. A fixing position 102 is reserved at the bottom to cooperate with the power conversion equipment 30 to achieve a fixed fit, and the power conversion equipment 30 has higher hanging stability.

[0054] During installation, the heat-resistant back panel 10 is first hung on the wall through the gourd hole 111, leveled, and then the other fixing holes 112 are fixed in sequence. Next, the power conversion device 30 is hung, and then the top cover 20 is fixed to the power conversion device 30. Finally, the fixing screws between the bottom fixing position 102 and the power conversion device 30 are tightened. The fixing screws between the bottom fixing position 102 and the power conversion device 30 enhance the connection strength of the power conversion device 30 and provide a certain degree of shock resistance.

[0055] The left and right side partitions 120 of this utility model prevent the human body from touching the heat sink 310 and play a role in isolating and preventing scalding. The top cover 20 plays a role in blocking foreign objects from falling onto the heat sink 310 and also plays a role in preventing scalding.

[0056] This invention overcomes the risk of burns caused by overheating of the radiator when the power conversion equipment is mounted indoors. It also overcomes the increased cost associated with adding an extra protective cover for indoor mounting of the power conversion equipment. Furthermore, it overcomes the risk of insufficient shock resistance when the power conversion equipment is mounted solely on a backrest.
