Novel metal base material shaping heat accumulating material and preparation method thereof

Abstract

The invention discloses a novel metal base material shaping heat accumulating material and a preparation method thereof. The heat accumulating material is prepared by compounding paraffin and porous foamy copper, wherein the mass fraction of paraffin is 83.2%, the mass fraction of porous foamy copper is 16.8%, the melting point of the selected paraffin in the material is 40-60 DEG C, and the voidage of the selected porous foamy copper is 98% or above. The material has the advantages that the heat absorption and discharge speed is quick, and the appearance after phase change is unchanged.

Description

1. Technical field [0001] The invention relates to the field of phase change heat storage materials, in particular to a heat storage material compounded with paraffin and porous copper foam. 2. Background technology [0002] Energy saving and environmental protection are an important topic in the field of energy utilization. Using phase change latent heat of phase change heat storage materials to store energy is a new type of energy saving technology. During the phase change process, the phase change material absorbs the heat of the surrounding environment, and releases heat to the surrounding environment when the temperature of the surrounding environment decreases, so as to achieve the purpose of controlling the temperature of the surrounding environment and saving energy. It has broad application prospects in solar energy utilization, heat energy recovery, air conditioning and refrigeration, building energy saving, aerospace and other fields.

Problems solved by technology

[0003] As a cheap and clean energy source, solar energy has been widely used in production and life. Matching and coordination, resulting in a lot of energy waste

For example, solar energy is excessive during the day, causing solar energy to be wasted in vain, and solar energy is not enough at night and in rainy days

The current heat storage materials generally have the disadvantage of poor thermal conductivity, so the phase change heat storage components made of them cannot fully exert the heat storage function of the heat storage material due to their poor thermal conductivity.

Secondly, when the heat storage material undergoes a solid-liquid phase transition, it will lead to the problem of liquid leakage
