Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and more specifically to a high-temperature resistant microchannel heat exchanger. Background Technology

[0002] As a core component of industrial heat transfer equipment, the technological development of heat exchangers has always revolved around increasing efficiency, compactness, and reliability. Traditional shell-and-tube heat exchangers have been widely used since the early 20th century, but they suffer from inherent drawbacks such as low heat transfer efficiency (overall heat transfer coefficient typically below 500 W / (m²·K)) and large size. To overcome these limitations, plate heat exchangers emerged in the 1960s, using corrugated plate designs to increase the heat transfer coefficient to over 6000 W / (m²·K), but insufficient pressure resistance restricts their application in high-pressure scenarios. Since the 21st century, microchannel heat exchangers have utilized flow channels with an equivalent diameter of less than 3 mm to double the surface heat transfer coefficient, but they are prone to clogging.

[0003] Insufficiency of existing technology: During the operation of existing microchannel heat exchangers, the heat exchange medium carries a large amount of heat energy. In the operation of existing equipment, the heat exchange medium is cooled by a condenser. However, if the heat exchange medium is directly cooled at a high temperature, the working power of the condenser will be high, but it is not easy to reduce the medium to the specified temperature, thus making it difficult to ensure heat exchange efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-temperature resistant microchannel heat exchanger to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant microchannel heat exchanger, comprising a heat exchange component, a medium condensation component fixedly connected to the outer side of the heat exchange component, a fan component installed on the inner side of the medium condensation component, the heat exchange component comprising a heat exchange cylinder, a positioning hole provided on the outer side of the heat exchange cylinder, heat exchange heads fixedly connected to the top and bottom of the heat exchange cylinder, a pipe port fixedly connected to the side of the heat exchange head away from the heat exchange cylinder, a positioning flange fixedly connected to the outer side of the pipe port, a first positioning circular plate fixedly connected to the top and bottom of the inner side of the positioning hole, and a heat exchange tube fixedly connected to the bottom of the first positioning circular plate.

[0006] Furthermore, the medium condensation assembly includes a delivery pump, condensation modules are fixedly connected to both sides of the delivery pump, a first pipe is fixedly connected to the side of the condensation module away from the delivery pump, a second pipe is fixedly connected to the side of the first pipe away from the condensation module, a bend is fixedly connected to the back of the second pipe, and a third pipe is fixedly connected to the other end of the bend.

[0007] Furthermore, the fan assembly includes a positioning frame, with a first positioning plate fixedly connected to the bottom and top of the inner side of the positioning frame, and second positioning plates fixedly connected to both sides of the positioning frame. A second positioning circular plate is fixedly connected to the second positioning plate and the side of the first positioning plate away from the positioning frame. A third positioning plate is fixedly connected to the bottom of the second positioning circular plate. A servo motor is fixedly connected to the back of the second positioning circular plate. A rotating shaft is fixedly connected to the output shaft of the servo motor. A positioning circular plate is fixedly connected to the front of the rotating shaft. Fan blades are fixedly connected to the outer side of the positioning circular plate. A transmission wheel is fixedly connected to the outer side of the rotating shaft. A transmission belt is provided on the outer side of the transmission wheel.

[0008] Furthermore, there is a clearance fit between the inner diameter of the heat exchange cylinder and the diameter of the first positioning circular plate on the outer side, and there is a clearance fit between the diameter of the positioning hole and the diameter of the third pipe.

[0009] Furthermore, the number of positioning holes and the diameter of the third pipe are matched, and the second positioning circular plate is connected to the rotating shaft through a bearing.

[0010] Furthermore, the outer diameter of the transmission wheel is the same as the outer diameter of the transmission belt, and the outer diameter of the rotating shaft matches the inner diameter of the transmission belt.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. In the operation of this utility model, the liquid to be cooled is introduced into the equipment through the top inlet and positioning flange. The liquid then enters the heat exchange head at the bottom through the heat exchange pipe. During the liquid heat exchange, the inside of the heat exchange cylinder is filled with heat exchange medium. Then, the heat exchange medium inside the heat exchange cylinder is driven by the working pump, and enters the condensation module through the third pipe, the bend pipe and the second pipe. Then, it enters the condensation module on the other side through the pump, the first pipe, the second pipe, the bend pipe and the third pipe and returns to the inside of the heat exchange cylinder. This allows the heat exchange medium to be recycled during the operation of the equipment without the need to replenish it. This effectively reduces the operating cost of the equipment.

[0013] 2. In the heat exchange process, this utility model uses a servo motor to drive the rotating shaft to rotate, which in turn drives the transmission wheel to rotate, and then drives the positioning disc and fan blades to rotate. Under the transmission belt, the transmission wheel at the bottom rotates, which in turn drives the positioning disc and fan blades at the bottom to rotate. This increases the airflow speed outside the second pipe, the bend, and the third pipe, effectively ensuring heat dissipation of the equipment. This effectively reduces the temperature of the medium entering the condensation module, ensuring that the condensation module will not be overloaded. Attached Figure Description

[0021] In a preferred embodiment, the medium condensation assembly 2 includes a delivery pump 201, condensation modules 202 fixedly connected to both sides of the delivery pump 201, a first pipe 203 fixedly connected to the side of the condensation module 202 away from the delivery pump 201, a second pipe 204 fixedly connected to the side of the first pipe 203 away from the condensation module 202, a bend 205 fixedly connected to the back of the second pipe 204, and a third pipe 206 fixedly connected to the other end of the bend 205. During operation, the liquid to be cooled is introduced into the equipment through the top inlet 104 and the positioning flange 105, and then the liquid enters the heat exchange head 103 at the bottom through the heat exchange pipe 107. Furthermore, during the liquid heat exchange process, the interior of the heat exchange cylinder 101 is filled with heat exchange medium. Then, the heat exchange medium inside the heat exchange cylinder 101 is driven by the operation of the transfer pump 201, and enters the condensation module 202 through the third pipe 206, the bend 205, and the second pipe 204. Then, it enters the condensation module 202 on the other side through the transfer pump 201, the first pipe 203, the second pipe 204, the bend 205, and the third pipe 206, returning to the inside of the heat exchange cylinder 101.

[0022] In a preferred embodiment, the fan assembly 3 includes a positioning frame 301. A first positioning plate 302 is fixedly connected to the bottom and top of the inner side of the positioning frame 301. Second positioning plates 303 are fixedly connected to both sides of the positioning frame 301. A second positioning circular plate 305 is fixedly connected to the side of the second positioning plate 303 and the first positioning plate 302 away from the positioning frame 301. A third positioning plate 304 is fixedly connected to the bottom of the second positioning circular plate 305. A servo motor 307 is fixedly connected to the back of the second positioning circular plate 305. A rotating shaft 306 is fixedly connected to the output shaft of the servo motor 307. A positioning circular plate 309 is fixedly connected to the front of the rotating shaft 306. A fan blade 3010 is fixedly connected to the outer side of the positioning circular plate 309. A transmission wheel 308 is fixedly connected to the outside of 06, and a transmission belt 3011 is provided on the outside of the transmission wheel 308. During the heat exchange process, the servo motor 307 drives the rotating shaft 306 to rotate, which in turn drives the transmission wheel 308 to rotate, and then drives the positioning circular plate 309 and the fan blade 3010 to rotate. Under the transmission of the transmission belt 3011, the transmission wheel 308 located at the bottom rotates, which in turn drives the positioning circular plate 309 and the fan blade 3010 located at the bottom to rotate. This increases the airflow speed outside the second pipe 204, the bend 205 and the third pipe 206, effectively ensuring the heat dissipation of the equipment and effectively reducing the temperature of the medium entering the condensing module 202, ensuring that the condensing module 202 will not be overloaded.

[0023] In a preferred embodiment, there is a clearance fit between the inner diameter of the heat exchange cylinder 101 and the outer diameter of the first positioning circular plate 106, and a clearance fit between the diameter of the positioning hole 102 and the diameter of the third pipe 206.

[0026] The working principle of this utility model is as follows: During operation, the liquid to be cooled is introduced into the equipment through the top inlet 104 and positioning flange 105. The liquid then enters the heat exchange head 103 at the bottom through the heat exchange pipe 107. During the liquid heat exchange process, the heat exchange cylinder 101 is filled with heat exchange medium. The heat exchange medium inside the heat exchange cylinder 101 is then driven by the delivery pump 201 to enter the condensation module 202 through the third pipe 206, the bend 205, and the second pipe 204. Then, it enters the condensation module 202 on the other side through the delivery pump 201, the first pipe 203, the second pipe 204, the bend 205, and the third pipe 206, returning to the inside of the heat exchange cylinder 101. This allows the heat exchange medium to be recycled without needing to be replenished during operation, effectively reducing the operating cost of the equipment.

[0027] During the heat exchange process, the servo motor 307 drives the rotating shaft 306 to rotate, which in turn drives the transmission wheel 308 to rotate, and then drives the positioning disc 309 and the fan blade 3010 to rotate. Under the transmission of the transmission belt 3011, the transmission wheel 308 located at the bottom rotates, which in turn drives the positioning disc 309 and the fan blade 3010 located at the bottom to rotate. This increases the airflow speed outside the second pipe 204, the bend 205 and the third pipe 206, effectively ensuring the heat dissipation of the equipment. This effectively reduces the temperature of the medium entering the condensation module 202, ensuring that the condensation module 202 will not be overloaded.
