Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe heat exchange, in particular to a heat pipe type heat exchanger. Background Art

[0002] The heat pipe is one of the components of the heat exchanger. It is a heat transfer component with high thermal conductivity. It uses the principle of heat conduction and the property of rapid heat transfer with a medium with a temperature difference to transfer the heat of an object to the other end through the heat pipe. It is used for heat exchange between the two media. The heat pipe heat exchanger has the advantages of high heat transfer efficiency, compact structure and small pressure loss. In the coal mining production industry, it is mainly used at the coal mine wellhead. In winter, the heat exchanger can exchange heat with the wind and introduce the hot air from the wellhead into the well, creating a comfortable working environment for the miners.

[0003] When optimizing existing heat pipe heat exchangers, most of the optimization is reflected in optimizing the heat exchange process and reducing the wellhead noise. For example, the Chinese utility model patent with application number CN202120457592.5 discloses "A high-efficiency and low-noise wellhead heat exchanger". In this device, the equipment casing is arranged in the air inlet heat exchange chamber of the mine wellhead room, and an adjustable louver air outlet is installed at the other end of the equipment casing, and a protective net is installed on one side of the adjustable louver air outlet, and a low-noise axial flow fan is installed on one side of the protective net. The heat exchange effect of the heat exchanger is enhanced by adding a fan, which avoids the problem of small heat exchange capacity of equipment far away from the wellhead and improves the utilization rate of the equipment; forced air supply is adopted to reduce the sealing requirements of the wellhead room, and low-frequency and low-noise axial flow fans are selected to reduce equipment operation noise and optimize the working environment of the wellhead room.

[0004] Although the above-mentioned heat pipe heat exchanger has certain advantages in reducing wellhead noise, it still has certain disadvantages: as one of the components of the heat exchanger, the heat pipe needs to be regularly inspected and maintained. If it is placed inside the equipment and it is not convenient to disassemble and assemble, it will cause trouble for manual operation. In addition, the equipment is used in coal mines. After the wind from the wellhead is sucked into the equipment, the coal dust and other impurities carried by the wind are easy to adhere to the outer surface of the heat pipe and form a covering layer, which affects the heat generated by the heat pipe and cannot be transferred well, resulting in poor heat exchange effect.
