Channel heat storage device

Abstract

The invention discloses a channel type heat storage device. According to the heat storage device, the heat storage efficiency can be greatly improved, the heat storage stability can be ensured, the heat storage performance of phase-change material is utilized, and heat storage and heat removal are effectively carried out; meanwhile, the phase-change heat storage is arranged into a plurality of phase-change heat storage units, the phase change material is filled in the phase-change heat storage unit shells in a non-full state, in this way, when the phase-change heat storage unit is subjected tovibration, the slight vibration of the phase-change material can guarantee the heat absorption and heat removal efficiency and uniformity of the phase-change material; meanwhile, the vibration is softer due to the arrangement of a hard elastic part, the service life of the phase-change heat storage units is protected, so that the phase-change material is uniform and slightly vibrated; and in addition, due to the arrangement of a shunting plate, the heat exchange uniformity of each heat storage capillary tube and each heat removal capillary tube can be guaranteed, and the heat storage and heatremoval efficiency and uniformity of the channel type heat storage device are further guaranteed.

Description

technical field [0001] The invention relates to a channel type heat storage device and belongs to the technical field of heat storage equipment. Background technique [0002] Heat storage refers to the storage of thermodynamic energy (heat) by corresponding devices. These devices are often integrated in the energy supply system, which is a means to alleviate the contradiction between energy supply and energy demand. There are many kinds of heat accumulators, among which the phase change heat accumulator is one of the hottest heat accumulators studied in recent years. The phase change heat accumulator is made of new chemical materials that can store heat energy. The thermal storage phase change material undergoes a biological phase change at a specific temperature (such as the phase transition temperature), accompanied by the absorption or release of heat, which can be used to control the temperature of the surrounding environment, or to store heat energy, which stores heat ...

AI Technical Summary

Problems solved by technology

The current phase-change heat accumulator generally passes through the phase-change material through the channel-type pipeline. When the heat accumulator with this common structure is used, it is easy for the phase-change material near the pipeline to easily absorb and discharge heat, and the heat away from it is easy. The phase change material of the pipeline has poor heat absorption and heat dissipation effects, resulting in poor heat storage effect of the heat accumulator, poor temperature uniformity, and low heat storage efficiency
