Abstract

The invention discloses a foamed-aluminum-based composite phase-change material, a preparation method thereof, a cooling partition plate and an electric vehicle battery box. The foamed-aluminum-basedcomposite phase-change material comprises a foamed aluminum base body and a phase-change material body, wherein the phase-change material body is loaded on the foamed aluminum base body, and the phase-change material body comprises paraffin and graphite. The foamed-aluminum-based composite phase-change material is low in density, has excellent high collision energy absorption performance, fireproof performance and sound insulation and noise reduction performance, and is wide in application range.

Description

technical field [0001] The invention relates to the field of materials, in particular, the invention relates to a foamed aluminum-based composite phase change material and a preparation method thereof, a cooling partition and an electric vehicle battery box. Background technique [0002] Improving the energy density of vehicle batteries is one of the ways to solve the problem of insufficient cruising range. However, due to the constraints of basic science, materials, and process technology, there are boundary effects in the improvement of battery energy density, and it is difficult to greatly improve the cruising capacity of new energy vehicles. . Experiments have proved that if the weight of the vehicle is reduced by 10%, the energy consumption efficiency can be increased by 6% to 8%. Improving battery thermal management capabilities can increase the cruising range of new energy vehicles on the existing basis. [0003] Aluminum foam is a new type of porous material with e...
