With the intensification of energy shortage and environmental pollution, the efficient utilization of energy and the application of clean energy are increasingly valued. Waste heat from exhaust air is a common but often wasted energy resource, and heat pipe technology, as an efficient heat transfer method, provides a new way for the recovery and utilization of waste heat from exhaust air.

Heat pipe is a device that achieves heat transfer through liquid evaporation and condensation, with high heat transfer efficiency, simple structure, and strong adaptability. Heat pipes are usually composed of a heat absorption section, an evaporation section, a condensation section, and a liquid pool. Through internal refrigerant circulation, heat is transferred from the heat absorption section to the condensation section, achieving efficient heat transfer.

Application of Waste Heat Recovery from Exhaust Air

Mine exhaust heat recovery: In mines such as coal mines, a large amount of exhaust heat is generated due to the ventilation inside the deep mine. Heat pipe technology can transfer the high-temperature waste heat inside the mine to the ground for heating, hot water, and other purposes, achieving efficient energy recovery.

Industrial waste heat recovery: Many industrial production processes generate a large amount of waste gas, which contains a large amount of thermal energy. Heat pipe technology can achieve the recovery and utilization of waste heat by transferring the remaining heat in the exhaust gas to other process fluids.
