Description

Technical Field

[0001] The present invention belongs to the technical field of motors, and in particular relates to a high-efficiency motor waste heat recovery and utilization device. Background Art

[0002] In industrial production, high-efficiency motors are widely used as core power equipment, generating significant amounts of waste heat during operation. Statistics show that approximately 30%-50% of electrical energy is ultimately lost as heat. Effectively recycling this waste heat would not only significantly improve energy efficiency but also reduce operating costs and carbon emissions, aligning with the "dual carbon" goals.

[0003] Currently, common motor waste heat recovery devices on the market mostly use simple pipe-type heat exchangers or air-cooled heat dissipation structures. These traditional devices have significant drawbacks: Firstly, due to insufficient heat exchange area and poorly designed heat transfer medium flow paths, they are unable to fully absorb the heat dissipated by the motor, resulting in a large amount of waste heat being wasted. Secondly, the devices have poor thermal insulation performance, and heat is easily lost to the outside through pipes and equipment casings during transmission and storage, reducing waste heat recovery efficiency.

[0004] To this end, the present invention provides a high-efficiency motor waste heat recovery and utilization device. Summary of the Invention

[0009] Preferably, the exhaust assembly includes a conical exhaust pipe and a second connecting pipe, the conical exhaust pipe is fixedly mounted on the top of the insulation shell, and the top of the conical exhaust pipe is fixedly mounted on the second connecting pipe. In this solution, the conical exhaust pipe can be designed to compress the air when it enters the second connecting pipe, thereby increasing the wind speed and temperature, while slowing down the heat loss of the air during transportation.

The heat dissipation dorsal fins 43 are provided in several groups, and several groups of heat dissipation dorsal fins 43 are fixedly mounted on the surface of the heat-conducting ring 42 in an annular shape; the water delivery mechanism 5 includes a water delivery pipe 51, a connecting ring 52 and a first connecting pipe 53. The water delivery pipe 51 is provided in several groups, and several groups of water delivery pipes 51 are fixedly mounted on the inner wall of the heat-conducting ring 42 in an annular shape. The water delivery pipe 51 is located in the gap between the heat dissipation dorsal fins 43, and the connecting ring 52 is fixedly mounted on the inner wall of the water delivery pipe 51. At both ends, the bottom of the surface of the connecting ring 52 is fixedly installed with the first connecting pipe 53, the water storage mechanism 6 includes a support frame 61, a water tank 62 and a water pump 63, the support frame 61 is fixedly installed at the bottom of the base frame 1, the inner wall of the support frame 61 is fixedly installed with the water tank 62, one side of the water tank 62 is fixedly installed with the water pump 63, the output end of the water pump 63 is fixedly installed with one group of first connecting pipes 53, the side of the water tank 62 away from the water pump 63 is fixedly installed with the other group of first connecting pipes 53, the exhaust assembly 7 includes a tapered exhaust pipe 71 and The second connecting pipe 72 and the conical exhaust pipe 71 are fixedly mounted on the top of the insulation shell 2. The top of the conical exhaust pipe 71 is fixedly mounted on the second connecting pipe 72. The exhaust mechanism 8 includes a supporting cross bar 81, a permanent magnet motor 82 and a fan 83. The supporting cross bar 81 is fixedly mounted on the inner wall of the conical exhaust pipe 71. The top of the supporting cross bar 81 is fixedly mounted on the permanent magnet motor 82. The bottom of the supporting cross bar 81 is rotatably mounted on the fan 83. The output end of the permanent magnet motor 82 is fixedly mounted on the permanent magnet motor 82. The inner wall of the insulation shell 2 is provided with insulation cotton.

[0020] like Figures 1 to 6As shown, the coordinated use of the fixing plate 41, the heat-conducting ring 42 and the heat-dissipating dorsal fin 43 can concentrate the temperature of the motor surface and store it inside the heat-insulating shell 2, so that the temperature inside the heat-insulating shell 2 can be increased, thereby preventing heat loss and allowing most of the heat to be reused. The coordinated use of the water pipe 51, the connecting ring 52 and the first connecting pipe 53 can enable the water to flow, and through heat exchange with the heat-conducting mechanism 4, the heat-conducting mechanism 4 can be cooled and the water can be heated, thereby realizing heat conversion for secondary utilization. The coordinated use of the support frame 61, the water storage tank 62 and the water pump 63 can achieve a water storage effect, and can also transport water to the water delivery mechanism 5 for circulating heating. To ensure that the water temperature can reach a suitable temperature for use, the conical exhaust pipe 71 can compress the air when it enters the second connecting pipe 72 through its conical design, thereby increasing the wind speed and temperature, while slowing down the heat loss of the air during transportation. The coordinated use of the supporting cross bar 81, the permanent magnet motor 82 and the fan 83 can generate suction to transport the heat flow inside the insulation shell 2 to the second connecting pipe 72, so that the user can use or store the heat flow. The insulation cotton can prevent the heat from being lost when stored inside the insulation shell 2, ensuring that the heat can be stored on the inner wall of the insulation shell 2. At the same time, the increase in temperature inside the insulation shell 2 can also accelerate the heating speed of the water flow in the connecting ring 52.

[0021] Working principle: When working, first place the base frame 1 on the ground, then the user first installs the motor to the inner wall of the heat-conducting ring 42, then starts the motor and starts using it. During use, the heat on the surface of the motor will be transferred to the heat-conducting ring 42, causing its surface temperature to rise, and then the heat-conducting ring 42 will transfer the temperature to the heat dissipation dorsal fin 43. Since the heat dissipation dorsal fin 43 is located inside the heat-insulating shell 2, the temperature of its surface will not be lost. When recovery is needed, first start the water pump 63 to extract the water inside the water tank 62 and transport it to the connecting ring 52 through the first connecting pipe 53. Then the connecting ring 52 will transport the water to the multiple water pipes 51 in sequence. Then, in the process of the water flow passing through the water pipe 51, it will be heated by the heat-conducting ring 42 and the heat dissipation dorsal fin 43. The heated dorsal fin 43 is heated and the heated water then flows back into the water tank 62 through the connecting ring 52 and the first connecting pipe 53 on the other side, and circulates until the water inside the water tank 62 is heated to a suitable temperature. At the same time, the user can also start the permanent magnet motor 82 during the start-up of the water pump 63 to drive the fan 83 to rotate. When the fan 83 rotates, it will extract the hot air inside the insulation shell 2 and transport it to the second connecting pipe 72 through the conical exhaust pipe 71. Then the user connects the second connecting pipe 72 to the pipeline to transport the heat flow to the storage device. Through the above structure, the waste heat of the motor can be fully recycled, further reducing heat loss and improving environmental protection.
