Novel phase change heat storage heating device

Abstract

The invention relates to a novel phase change heat storage heating device. The device comprises phase change heat storage modules, a water tank, a fan, a heat exchanger and a thermal insulation layer, wherein each phase change heat storage module consists of an electric heater and a phase change heat storage material, and is filled with a certain amount of phase change material; an electric heating device is fixedly arranged in a cavity in a tank body and is internally arranged in the phase change material. According to the device, instable electric energy is continuously stored by using the phase change material and then is stably output, so that the electric energy is more efficiently utilized to achieve a continuous hot water supply effect. According to the device, the heat accumulated by the phase change material is brought away by circulating air and then is transferred to cold water in the heat exchanger, so that direct contact of the phase change heat storage modules and heat exchange water is avoided, and the risk that the cold water is polluted is avoided. The phase change heat storage modules are fixedly arranged on a pedestal through clamping grooves of the same size, so that the number of the heat storage modules can be flexibly controlled to adjust the heat storage power of the heat storage modules. The device has the advantages of modularized assembly, convenience in maintenance, high efficiency, low cost, less investment, small occupied space and the like.

Problems solved by technology

However, the heat storage material used in the electric oil tank is heat transfer oil, which stores heat in the form of sensible heat. Compared with the latent heat storage method of phase change heat storage materials, not only the heat storage density is low, but also the heat transfer oil is unsafe.
