Phase change metal alloy, phase change metal alloy constant-temperature quilt and preparation method for phase change metal alloy

Abstract

The invention relates to phase change metal alloy, a phase change metal alloy constant-temperature quilt and a preparation method for the phase change metal alloy, and aims at providing the low-melting-point metal alloy with the phase change temperature being 26 DEG C and application of the metal alloy to the constant-temperature quilt. The low-melting-point metal alloy with the phase change temperature being 26 DEG C is composed of gallium, indium, bismuth and cesium. The phase change metal alloy constant-temperature quilt comprises a quilt body, and is characterized in that a constant-temperature interlayer is arranged in the quilt body and comprises one or more heat preservation layers and one or more constant-temperature layers, each heat preservation layer is prepared from slurry coating and phenolic resin hollow microspheres, and each constant-temperature layer is prepared from phase change microcapsules and slurry coating. The low-melting-point metal alloy with the phase change temperature being 26 DEG C serves as the phase change materials in the phase change microcapsules. The low-melting-point metal alloy with the phase change temperature being 26 DEG C can be widely applied to the fields of thermal contact resistance reduction, contact resistance reduction and phase change energy storage, and the phase change metal alloy constant-temperature quilt can be applied to daily lives of people.

Description

technical field [0001] The present invention relates to a phase-change metal alloy, an alloy constant temperature quilt and a preparation method of the alloy, in particular to a phase-change metal alloy with a phase-change temperature of 26°C. The composition of the phase-change metal alloy is gallium indium bismuth cesium alloy. Excellent thermal conductivity, electrical conductivity and energy storage capacity, not only can be used in the phase change metal constant temperature quilt described in the present invention, but also can be widely used in the field of reducing contact thermal resistance, contact resistance and phase change energy storage; the phase change metal of the present invention Constant temperature can be used in people's daily life. Background technique [0002] At present, electric heating quilts, electric blankets, etc. on the market all arrange resistance wires in the quilts, and generate heat by energizing the resistance wires, and use them while en...

AI Technical Summary

Problems solved by technology

Because the resistance wire is charged, when it is powered on for a long time, there will be leakage due to problems such as wire aging, which will cause fire, personal safety and other safety hazards.

[0003] The latest constant temperature quilt technology uses hot air pump to circulate hot air to keep the quilt constant temperature, but it has the following disadvantages: (1) The quilt requires many objects and has a complicated structure; The air is heated and circulated to keep the quilt at a constant temperature. Therefore, it is also necessary to energize during use, which may cause electricity leakage due to aging wires and other problems, endangering personal and property safety; (3) The heated air needs to be heated by an air pump. Loop, which will generate more or less noise, affecting the user's sleep quality
