A Modular Solar Thermal Storage System for Extreme Conditions

Abstract

The invention relates to a modularized solar heat storage system applied under extreme conditions. The system comprises a solar cell panel, an electric governor, a heat insulation material, cooling fins, composite phase change heat storage materials, an electric heating plate, a cold water pipe, a hot water pipe, a temperature control valve, a bypass water pipe and a water pipe joint. The heat storage system is of a portable modularized structure the size of which can be adjusted easily, multi-module assembly and disassembly can be achieved fast according to actual needs. The main part of the modularized solar heat storage system is the dense and light aluminum alloy cooling fins with high thermal conductivity, gaps between the cooling fins are filled with the medium and low temperature composite phase change heat storage materials, the electric heating plate is placed between the heat insulation material and the cooling fins, and the helicoid cold water pipe and the helicoid hot water pipe are arranged on the two sides of the electric heating plate respectively. The modularized solar heat storage system can be mounted under the indoor floor of the polar region. When indoor temperature is extremely high or extremely low, heat storage or heat releasing is achieved through the change of the phase state of the phase change heat storage materials, and then fluctuation of the indoor temperature is reduced and the comfort level of a room is improved.

Description

technical field [0001] The invention belongs to the field of heat transfer and energy storage, and in particular relates to a modularized solar heat storage system applied under extreme conditions. In the cold Antarctic or remote plateau areas, there is no access to the grid, and solar power cannot be integrated into the grid. In this case, solar panels can be used to generate electricity to supply the electricity needs of the house first, and the remaining electricity can be stored for backup through a modular thermal storage system. The modular heat storage system can be arranged under the indoor floor, using phase change heat storage materials for heat storage and release, reducing indoor air fluctuations and improving room comfort. Background technique [0002] With the development of science and technology, scientists spend more and more time conducting scientific research in regions such as polar regions and plateaus. Working in places where these natural conditions ...
