Self-contained thermal distribution and regulation device for cold weather apparel

摘要

A thermal distribution and regulation system for a garment that includes a self-contained heat source, such as a catalytic heat source. A heat manifold extends about a surface of the heat source and is mechanically adjusted relative to the surface of the heat source to control the contact surface area between the heat source and heat manifold to regulate heat conducted from the heat source. The heat manifold is configured to engage the surface of the heat source at more than one predetermined location to prevent inadvertent movement between the heat source and heat manifold. The system also includes a plurality of heat conductors coupled to the heat manifold and affixed to the garment. An end of each heat conductor is coupled to the heat manifold for conducting heat from the heat manifold to the garment to warm the garment.
