Problems solved by technology

However, a single paraffin has the disadvantages of liquid phase flow, slow heat transfer and fast heat dissipation.
Although there are currently researches on paraffin phase change composite materials, such as paraffin-graphite, paraffin-perlite, paraffin-vermiculite and other phase change composite materials, the insulation effect and i

Embodiment 1

[0018] Heat to melt the paraffin into liquid (i.e. solid-liquid phase transition), place the felt block punched into the required shape and size into the melted paraffin and soak it, after the felt block is fully adsorbed, take it out and cool down to solidify, which is the process of the present invention Paraffin-felt phase change composite heat storage materials. In large-scale production, the whole piece of felt can be absorbed by the conveying device to condense the paraffin and then punched according to the requirements.

Embodiment 2

[0020] Heat to melt the paraffin wax into a liquid (that is, solid-liquid phase change), add 10% PE wax (polyethylene wax (PE-WAX)) by weight, and place the felt block punched into the desired shape and size to melt After the felt block is fully absorbed, it is taken out and cooled to solidify, and then the paraffin-felt phase change composite heat storage material of the present invention is produced. In large-scale production, the whole piece of felt can be absorbed by the conveying device to condense the paraffin and then punched according to the requirements.

Embodiment 3

[0022] Heat the refined paraffin or semi-refined paraffin with a melting point of 58-60°C to melt into liquid (that is, solid-liquid phase transition), and place the felt block punched into the desired shape and size in the melted paraffin, and the felt block is fully absorbed Afterwards, it is taken out and cooled to solidify, and the paraffin-felt phase change composite heat storage material of the present invention is produced. In large-scale production, the whole piece of felt can be absorbed by the conveying device to condense the paraffin and then punched according to the requirements.

Abstract

The invention discloses a paraffin-felt phase-changing composite heat storage material, which mainly comprises paraffin and a felt. The felt is placed in melted paraffin for immersion, and after the felt is fully saturated, the felt is taken out and congealed to prepare the material. According to the paraffin-felt phase-changing composite heat storage material, paraffin is adopted as a phase-changing material, the felt is used as an absorption and support structure to prepare the material, thus the defects of flowing paraffin in a liquid phase and rapid radiation are overcome, and the prepared paraffin-felt phase-changing composite heat storage material has the advantages of a light proportion, fundamental non-flowing, a stable shape, zero corrosion and better and unexpected effects on heat storage and heat preservation.

Description

technical field [0001] The invention relates to a paraffin-felt phase-change composite heat storage material and a heat storage device prepared by using the paraffin-felt phase-change composite heat storage material. Background technique [0002] When the weather is cold in winter, people are accustomed to heating with electric hot water bags, and electric hot water bags have become an indispensable article for people to keep out the cold. But the electric hot water bag adopts water as heat storage medium, and the fluidity of water is strong, and can scald people when electric hot water bag leaks liquid, and easily cause water bag to expand and explode, can cause very big potential safety hazard to people. [0003] Paraffin wax has the advantages of long-term stable physical and chemical properties, high heat storage rate, wide range of sources, low price, no pollution, and no corrosion. It is an ideal phase change heat storage material. People try to use it instead of water...
