    • A refrigerant-containing bladder or container is positioned underneath the body. Heat absorbed from the body vaporizes the refrigerant, which expands to cooler remote regions of the bladder. Heat is then withdrawn from the edges of the container by thermally conductive pathways that distribute heat from this container to a cooler area that is not underneath the body. The cooled refrigerant condenses, and is returned to the regions of the device that are under or adjacent to the central and warmest parts of the body. The heavier and warmer portions of the body force the bladder to the lowest point. Alternatively, heat is transferred from the body via a specific highly thermally conductive layer or layers of material(s) that is (are) soft, pliable, and comfortable to sit or lie on. This layer joins conductive materials that are configured to transport heat and diffuse it to the cooler environment.
    • 含制冷剂的气囊或容器位于身体下方。 从身体吸收的热量使致冷剂蒸发,从而膨胀到气囊较冷的偏远区域。 然后通过将热量从该容器分配到不在身体下方的较冷区域的导热通道从容器的边缘排出热量。 冷却的制冷剂冷凝并返回到设备的位于身体的中部和最热的部分下面或附近的区域。 身体较重和较暖的部分将膀胱压至最低点。 或者,热量通过特定的高度导热的层或材料层从身体转移,所述材料层柔软,柔韧,舒适地坐着或躺着。 该层连接导电材料,其配置为传输热量并将其扩散到较冷的环境。
