Technical Field

[0001] The utility model belongs to the technical field of motor covers, and in particular relates to a fully covered motor cover which is convenient for heat dissipation. Background Art

[0002] When the motor is working outdoors, it faces direct sunlight and generates a lot of heat. If the heat cannot be dissipated promptly and effectively, the temperature of the motor will rise, which can easily cause the motor circuit to burn out, causing the entire circuit to burn out, and even cause a fire, which is extremely harmful.

[0003] The motor includes a stator consisting of an iron core and windings, a rotor, end covers, a shaft, bearings, a heat dissipation system, terminals and protective devices.

[0004] The existing heat dissipation system includes a fan arranged at the rear of the motor. The fan is used for heat dissipation only, and the heat dissipation effect is weak, which affects the use of the motor. Therefore, we design a fully enclosed motor cover that is convenient for heat dissipation. Summary of the Invention

[0005] In view of the problems existing in the background art, the present invention provides a fully enclosed motor housing that facilitates heat dissipation, including a sunshade with a heat dissipation hole in the middle and a housing mounted on the bottom. The housing and the sunshade are connected by a snap-convex connection. A limit protrusion I and a limit protrusion II are symmetrically provided on the left and right sides of the inner wall of the housing, respectively. A slot I and a slot II are symmetrically provided on the left and right sides of the heat dissipation hole of the sunshade, respectively, to cooperate with the limit protrusions I and II.

The heat pipe radiator comprises a sealing tube, a liquid wick, and a vapor channel. The heat pipe radiator operates based on the principles of heat conduction and phase change.

A base is mounted on the bottom of the housing, which is welded to the housing. The base is surrounded by air inlets and is mounted on the base. The first cooling fan is mounted on the base.

[0006] When working outdoors, the outer diameter of the sunshade is larger than the outer diameter of the shell, which avoids direct sunlight for heat dissipation of the heat pipe and provides a larger heat dissipation area.

[0007] The limiting protrusion I and the clamping groove I are in interference fit, and the limiting protrusion II and the clamping groove II are in interference fit, which effectively improves the degree of fixing firmness.

[0008] An air inlet is provided on the frame of the base; a first cooling fan is installed in the center of the base, and the first cooling fan is fixedly connected to the inner wall of the base. The fan model is DC fan SY6015.

[0009] As an optimal technical solution of the present invention, according to air flow, hot air rises and cold air falls. The first cooling fan is located in the center of the base and adopts a bottom-up blowing method, which conforms to the principle of air flow, can accelerate air flow and increase heat dissipation efficiency.

[0010] Preferably, the sunshade is made of double-coated flame-retardant material. Preferably, the fins are connected to the shell by welding.

[0011] Preferably, the solar panel provides electric energy for the first cooling fan and the second cooling fan, which has the effect of energy saving and environmental protection.

[0012] Preferably, the heat pipe radiator is connected to the fins using through-fins, utilizing the heat pipe phase change principle to increase heat transfer speed and improve heat dissipation efficiency.

[0013] Preferably, a small second cooling fan is installed on the surface of the shell. The model of the second cooling fan is DC fan SY4010. The second cooling fan is connected to the shell by welding to provide a cooling effect for the heat pipe radiator and improve the heat dissipation effect of the heat pipe radiator.

[0014] In summary, the beneficial effects of the present invention are:

[0015] (1) The fully enclosed motor cover for easy heat dissipation is provided with a sunshade, which can effectively block sunlight, prevent the motor and heat pipe radiator from being exposed to the sun, reduce the motor temperature, extend the motor service life, help keep the motor running within the optimal temperature range, provide a larger heat dissipation area for the heat pipe radiator, and improve the motor reliability and work efficiency.

[0016] (2) The heat pipe radiator is installed on the surface of the shell and is connected to the fins welded on the surface of the shell through the fin, which increases the heat dissipation area and utilizes the heat transfer and phase change principles to improve the heat dissipation efficiency. The second heat dissipation fan welded on the surface of the shell increases the heat transfer speed of the heat pipe radiator and improves the heat dissipation efficiency.

[0026] like Figures 1 to 5As shown, a fully enclosed motor housing for facilitating heat dissipation comprises a motor housing body 10, which includes a sunshade 1 having heat dissipation holes 6 formed on its surface. A housing 2 is provided on the end surface of the sunshade 1, distal from the heat dissipation holes 6. The housing 2 is connected to the sunshade 1 via a snap fastener. The inner wall of the housing 2 is symmetrically provided with a limit protrusion I 11 and a limit protrusion II 14 on the left and right sides, respectively. The heat dissipation holes 6 of the sunshade 1 are symmetrically provided with a slot I 12 and a slot II 15, which cooperate with the limit protrusions I 11 and II 14. A heat pipe radiator 4, a second cooling fan 9, and fins 13 are mounted on the surface of the housing 2. The heat pipe radiator 4 comprises a sealing tube, a liquid wick, and a vapor channel. It has the advantages of fast thermal response, small size and light weight, no need for an external power supply, and no need for special maintenance during operation. The heat pipe radiator 4 operates based on the principles of heat conduction and phase change, rapidly transferring heat from the housing 2 to the heat pipes beneath the sunshade 1. A second cooling fan 9 accelerates heat dissipation from the heat pipes. The heat pipes are mounted on the surface of the housing 2 via fins 13. The bottom of the housing 2 is welded to a base 3. The base 3 is surrounded by air inlets 5, and a first cooling fan 8 is mounted in its center.

[0027] The fully enclosed motor cover for heat dissipation provided by the embodiment of the present disclosure can achieve higher heat dissipation efficiency through the heat pipe radiator 4 and changing the air flow.

[0028] Furthermore, when working outdoors, the outer diameter of the sunshade 1 is larger than the outer diameter of the housing 2, which prevents the heat pipe radiator 4 from being directly exposed to sunlight and provides a larger heat dissipation area.

[0029] like Figure 4 、 Figure 5 The limiting protrusion I11 and the clamping groove I12 are interference fit, and the limiting protrusion II14 and the clamping groove II15 are interference fit, which effectively improves the fixing firmness.

[0030] See Figure 1 As shown, a first cooling fan 8 is installed in the center of the base 3. The first cooling fan 8 is fixedly connected to the inner wall of the base 3. The model of the first cooling fan is DC fan SY6015.

[0031] As a preferred technical solution of the present invention, according to air flow, hot air rises and cold air falls. The first cooling fan 8 adopts a bottom-up blowing method, which conforms to the air flow principle, can accelerate air flow and increase heat dissipation efficiency.

[0032] Furthermore, the sunshade 1 is made of double-coated flame-retardant material, which has the advantages of heat insulation and sun protection.

[0033] Furthermore, the fins 13 are connected to the housing 2 by welding, thereby increasing the stability and heat dissipation capability of the device.

[0034] Furthermore, solar panels 7 are mounted around the sunshade 1 at a position away from the housing 2. The connectors of the solar panels 7 are connected to a first cooling fan 8 and a second cooling fan 9 via cables. The solar panels 7 provide power to the first cooling fan 8 and the second cooling fan 9, thereby achieving energy conservation and environmental protection. The connection method between the solar panels and the cooling fans is conventional and will not be described in detail here.

[0035] Furthermore, the heat pipe radiator 4 is connected to the fins 13 using through-fins, utilizing the heat pipe phase change principle to increase heat transfer speed and improve heat dissipation efficiency.

[0036] Furthermore, a second cooling fan 9 is installed on the surface of the shell 2. The model of the second cooling fan 9 is a DC fan SY4010. The second cooling fan 9 is connected to the shell 2 by welding to provide a cooling effect for the heat pipe radiator 4 and improve the heat dissipation effect of the heat pipe radiator 4.

[0037] The use process and working principle of this utility model:

[0038] When discussing this fully enclosed motor housing for heat dissipation, we cannot help but emphasize its unique advantages in outdoor operating environments. The design cleverly integrates multiple elements, including a sunshade, heat pipe radiator, cooling fan, and solar panels, to form an efficient and environmentally friendly cooling system.

[0039] During outdoor operation, strong direct sunlight often causes the motor and surrounding components to heat up dramatically, affecting the motor's operating efficiency and lifespan. This fully enclosed motor cover, however, securely connects the sunshade to the outer casing via a snap-on connection. This not only effectively blocks direct sunlight but also provides a relatively cool operating environment for the motor and heat pipe radiator. This design not only reduces motor temperature but also significantly extends its operating life, ensuring continuous and stable operation within the optimal temperature range. To further enhance heat dissipation, heat pipe radiators are installed on both the sunshade and the outer casing.

[0040] The heat pipe radiator utilizes the principles of heat conduction and phase change to quickly transfer heat generated by the motor to the radiator surface, where it is then dissipated into the air with the assistance of a cooling fan. Notably, this cover also features innovative design for the heat pipe radiator. By connecting the heat pipe radiator to the fins through through-holes, the heat dissipation area is significantly increased, thereby improving heat dissipation efficiency. Furthermore, a small second cooling fan is welded to the surface of the housing, providing additional cooling for the heat pipe radiator and further ensuring the motor's heat dissipation needs.

[0041] The base is surrounded by air inlets, with a primary cooling fan installed in the center. This fan blows air from the bottom up, in line with the natural law of air flow: hot air rises and cold air falls. This accelerates the flow of air around the motor, drawing in cool air from the bottom and exhausting hot air from the top through the cooling system, creating a highly efficient cooling cycle. This design not only improves cooling efficiency but also reduces the motor's operating temperature, extending its lifespan.

[0042] Furthermore, the cover fully utilizes solar energy. Solar panels installed on the top of the sunshade not only provide power for the first and second cooling fans, achieving energy conservation and environmental protection, but also reducing dependence on traditional energy sources. This green, low-carbon design concept is highly consistent with the current global sustainable development strategy.

[0043] This heat-dissipating, fully enclosed motor cover, through its unique design and innovative cooling technology, successfully addresses the challenge of high-temperature motor operation in outdoor operating environments. It not only improves motor efficiency and lifespan, but also achieves energy conservation and environmental protection, injecting new vitality into the development of the motor industry.

[0044] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
