Description

Technical Field

[0001] This invention relates to the field of battery heat insulation sheet testing technology, and in particular to a testing device based on a high-temperature resistant battery heat insulation sheet. Background Technology

[0002] Thermal insulation materials are classified into three categories: porous materials, heat-reflective materials, and vacuum materials. Porous materials utilize the inherent pores within the material for insulation, as the air or inert gases within these pores have very low thermal conductivity; examples include foam materials and fiber materials. Heat-reflective materials have a high reflectivity, reflecting heat away; examples include gold, silver, nickel, aluminum foil, or metal-plated polyester and polyimide films. Vacuum insulation materials utilize the internal vacuum of the material to block convection for insulation. The aerospace industry has stringent requirements for the weight and volume of insulation materials, often requiring them to also possess sound insulation, vibration damping, and corrosion resistance properties. The needs for insulation materials vary among different aircraft. Foam plastics, superfine glass wool, high-silica cotton, and vacuum insulation panels are commonly used for insulation in aircraft cockpits and cabins.
