A shell-and-tube heat exchanger combining heat pipes and phase change materials

Abstract

The invention provides a heat tube and phase change material combined shell-and-tube heat exchanger. The system comprises a shell, a cooling liquid inlet, a cooling liquid outlet, a heat tube, a powerpump, a cold medium source and a heat source shell. The shell is filled with cooling liquid. The heat source shell is arranged in the shell. The heat source shell internally comprises a heat source and a phase change material. The heat source surrounds the interior of the phase change material. The evaporating end of the heat tube is arranged in the phase change material. A second temperature sensor is arranged on the surface of the heat source shell and is in data connection with a controller. The controller automatically controls the opening degree of a valve according to the detected temperature data. By controlling the temperature of the surface of the heat source shell, the temperature of the heat source is prevented from being too high or too low, and the effect of automatically controlling and saving energy is realized. Heat generated during conveying of the heat tube is used, the phase change heat transferring is realized through the liquid, and the heat exchange problem of high heat flux density can be quite well solved.

Description

technical field [0001] The invention relates to the field of shell and tube heat exchangers, in particular to a submerged shell and tube heat exchanger. Background technique [0002] Shell-and-tube heat exchangers are widely used in chemical, petroleum, refrigeration, nuclear energy and power industries. Due to the worldwide energy crisis, in order to reduce energy consumption, the demand for heat exchangers in industrial production is also increasing. The quality requirements for heat exchangers are also getting higher and higher. In recent decades, although compact heat exchangers (plate, plate-fin, press-welded plate heat exchangers, etc.), heat pipe heat exchangers, direct contact heat exchangers, etc. have been developed rapidly, but due to the The heat exchanger has a high degree of reliability and wide adaptability, and it still occupies a dominant position in output and consumption. According to relevant statistics, the current consumption of shell-and-tube heat exc...

Problems solved by technology

[0006] However, the current immersion heat exchanger has problems such as low heat transfer efficiency, so in general, it is necessary to add stirring components to increase heat transfer

Relatively low heat transfer efficiency
