Embodiment 1

[0050] Step 1, process the aluminum alloy into a concave frame with screw holes by casting, the thinnest part is 2mm, and the thermal conductivity of the obtained aluminum alloy frame is 160W / (m·K);

[0051] Step 2: heating and melting polyethylene, mixing evenly with phase change material microcapsules and aluminum powder with a phase change temperature of 70°C at 120°C, the mass ratio of polyethylene, phase change material microcapsules, and aluminum powder is 3.5:5.5 : 1. The plate-type phase change energy storage structural part is obtained by mold forming, and its appearance size corresponds to the concave aluminum alloy skeleton, so that it can be installed in the aluminum alloy skeleton. The thermal conductivity of the obtained phase change energy storage structural part is 2W / (m K);

[0052] Step 3: Bond the phase-change energy storage structure to the aluminum alloy frame with a 5W heat-conducting phase-change sheet, and fix it with stainless steel sheets and screws. ...

Abstract

The invention provides a rapid-heat-storage high-strength phase change energy storage composite structural member and a preparation process thereof, and relates to the technical field of materials, inparticular to a composite structural member. The rapid-heat-storage high-strength phase change energy storage composite structural member consists of a metal framework, a heat-conduction sealant, a phase change energy storage structural member and a screw fixing device. The metal framework not only has a main structure supporting effect, but also can rapidly absorb heat of a heat source and an environment and uniformly dissipate the heat to the metal framework; by the heat-conduction sealant, rigid contact between the phase change energy storage structural member and the metal framework can be eliminated, and the heat absorbed by the metal framework is rapidly conducted to the phase change energy storage structural member; and density of resin and phase change material microcapsules in the phase change energy storage structural member is small, and thus, the rapid-heat-storage high-strength phase change energy storage composite structural member has the advantages of the excellent mechanical property, high heat storage capacity, high heat storage speed, light weight, small thickness and the like.

Description

technical field [0001] The invention relates to the field of material technology, in particular to composite structural parts. Background technique [0002] Phase change material is a kind of material that absorbs or releases a large amount of latent heat of phase change through solid-liquid phase transition, while maintaining a constant temperature or a small temperature change. It is widely used in aerospace, electronic communications, solar energy and other fields. Specifically, it can be used in aircraft, base stations, power supply control cabinets and other places. However, phase-change material structural parts store heat slowly and have poor mechanical properties, so they cannot be applied to places where heat has a peak-to-valley effect and at the same time needs to bear a large force. Contents of the invention [0003] The purpose of the present invention is to provide a fast heat storage high-strength phase change energy storage composite structural member, whi...
