Heat-pipe heat exchanger and heat exchange method

Abstract

The invention relates to the field of thermal energy and power engineering, in particular to a heat-pipe heat exchanger and a heat exchange method. The heat-pipe heat exchanger comprises a heat pipe housing, at least one radiator, at least one heat collector, a heat insulating layer and an exhaust liquid-filling port, wherein the heat pipe housing comprises a single inner space, a heat transfer medium is filled into the lower portion of the inner space, each radiator is filled with a radiating medium, the radiators are positioned on the lower portion of the inner space and immersed in the heat transfer medium, each heat collector is filled with a heat collection medium, the heat collectors are positioned on the upper portion of the inner space and above the liquid level of the heat transfer medium, the heat insulating layer warps the outer wall of the heat pipe housing, the exhaust liquid-filling port is reserved at the top of the heat pipe housing or on the upper portion of the lateral wall of the heat pipe housing, the heat transfer medium is filled into the heat pipe housing through the exhaust liquid-filling port, and gas in the heat pipe housing is exhausted through the exhaust liquid-filling port. The heat-pipe heat exchanger is simple in structure, convenient in maintenance and better in heat exchange effect.

Description

technical field [0001] The invention relates to the field of thermal energy and power engineering, in particular to a heat pipe heat exchanger and a heat exchange method. Background technique [0002] The heat pipe heat exchanger has the characteristics of high heat exchange efficiency, uniform temperature, and heat exchange under small temperature difference conditions, and has been widely used in engineering. In a common heat pipe heat exchanger, a layer of separator is used to separate the heat dissipation medium from the heat collection medium, and an appropriate number of heat pipes are installed on the separator, and one end of the heat pipe is placed in the heat dissipation medium to absorb heat, and the other end is placed in the heat dissipation medium. In the heat-collecting medium to release heat, both the heat-dissipating medium and the heat-collecting medium flow outside the heat pipe. [0003] This type of heat pipe heat exchanger has complex structure, diffic...
