Phase change material and plate type heat exchanger combined phase change energy storage tank

Abstract

The invention discloses a phase change material and plate type heat exchanger combined phase change energy storage tank. Heat is absorbed by the phase change of a phase change energy storage material, and is stored in the phase change energy storage material, so that the energy storage tank forms a heat-preservation tank for ensuring the heat utilization of a user at any time. The energy storage tank comprises a tank body, plate type heat exchangers and electric auxiliary heaters, wherein a solid-liquid phase change energy storage material is filled in the tank body; the plate type heat exchangers and the electric auxiliary heaters are arranged in the solid-liquid phase change energy storage material in the tank body; a maintenance hole is formed in the tank body; a heat-preservation layer is arranged outside the tank body. According to the energy storage tank, heat can be absorbed by the heat exchange of the energy storage material, and is stored in the phase change energy storage material, so that the energy storage tank forms the heat-preservation tank for ensuring the heat utilization of the user at any time; the continuous and constant temperature running of a heating system can be ensured, and heating quality is ensured; on the basis of providing the same heat, the size of the tank body can be reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a phase change energy storage box in which a phase change material is combined with a plate heat exchanger. Background technique [0002] With the continuous improvement of people's living standards, people's demand for domestic hot water is also increasing. People hope that when they want to use hot water, they can use it directly without waiting, and at the same time require to ensure its quality and constant temperature water supply. [0003] Most of the current hot water supply systems adopt a structural design in which a heat exchanger is installed in a water tank. The water in the water tank is heated by a heat exchanger, and then supplied to users. [0004] Because the heat exchange effect of the heat exchanger is relatively low, the volume of the general water tank is relatively large. At the same time, because the heat transfer of the heat exchanger is affected b...

Problems solved by technology

[0004] Because the heat transfer effect of the heat exchanger is relatively low, the volume of the general water tank is relatively large

At the same time, because the heat transfer of the heat exchanger is affected by the heat source, it often causes the instability of the water supply temperature and affects the use
