Unverified隔热性能取决于材质厚度与涂层，双层铝箔+气泡层隔热效果远优于单层遮光布，但收纳体积大、不易折叠，需权衡后备箱空间80% similarUnverified外壳材质与散热权衡：铝合金散热好但快充时更烫手且导电需做绝缘处理，塑料外壳更安全但高功率下易积热，20W以上快充优先塑料+散热结构76% similarUnverified铝箔防潮垫的隔热效果取决于铝箔纯度和发泡基材，双面铝箔+PE发泡结构的热反射率可达90%以上，常用于地暖找平层的隔潮反射76% similarUnverified厚度越薄贴合性越好、越不影响装配，但横向导热截面积越小散热能力越弱；追求极致散热应选带铜箔或石墨复合的稍厚版本76% similarUnverified导热均匀性看锅底结构：三层复合底（不锈钢-铝-不锈钢）或多层夹钢底比单层底受热更均匀不易局部糊底，铝夹层越厚蓄热越好，是判断中高端不锈钢锅的关键76% similar
