Heat pipe type heat exchanger

Abstract

The invention provides a heat pipe type heat exchanger. Theheat pipe type heat exchanger comprises a porous medium material, an integrated heat pipe and a high-temperature heat exchanger, wherein theintegrated heat pipe comprises a heat pipe condensation section, a heat pipe heat insulation section and a heat pipe evaporation section which are connected in sequence, the heat pipe evaporation section is embedded in the porous medium material, and the heat pipe condensation section is embedded into the high-temperature heat exchanger. According to the heat exchanger, gas and air are mixed and burnt in the porous medium material, so that the heat exchange surface area is expanded by flue gas and the porous medium material, the heat transfer effect is enhanced, and the heat exchange coefficient is improved; and meanwhile, theintegrated heat exchange pipe is adopted, and high-temperature heat is uniformly conveyed into a heater of a power device, so that the high-efficiency, high-temperature and uniform heat exchange process of fuel in the power device is realized, the problems that a heating pipe is prone to being burnt out and heat exchange is difficult to strengthen due to the factthat at present, an engine is heated by directly utilizing the high-temperature flue gas are solved, and the later assembly and installation are facilitated.

Description

technical field [0001] The invention relates to the field of heat exchanger devices, in particular to a heat pipe heat exchanger and a power device comprising the heat pipe heat exchanger. Background technique [0002] The thermoacoustic effect is a physical phenomenon in which heat induces acoustic self-excited oscillations in elastic media that are mainly high-pressure inert gases. Utilizing the thermoacoustic phenomenon that heat generates self-excited oscillation in pressure gas, heat can be converted into pressure fluctuations, that is, sound waves. Pressure waves are alternating mechanical energy, that is, heat energy is converted into mechanical energy. [0003] Heat pipe technology makes full use of the heat conduction principle in the thermoacoustic effect and the rapid heat transfer properties of phase change media. Through the heat pipe, the heat of the heating object is quickly transferred to the outside of the heat source, and its thermal conductivity exceeds th...
