A cooling device uses an endothermic chemical reaction for cooling. The cooling device includes a sealed casing with at least two reagents that generate an endothermic chemical reaction when they come into contact. The cooling device further includes a separating membrane separating the reagents in a storage position; a contact-making system which can be activated and configured to bring the reagents into contact with one another when activated, an interface element for activating the contact-making system; and a thermal interface with a thermally conductive metal base plate. One of the surfaces of the base plate is subjected to the endothermic chemical reaction, and the other surface of the base plate is accessible from outside the cooling device.

An energy conversion system for use in a rifle with a barrel and a handguard includes an interface with a curved surface that conforms substantially to a curvature of the barrel such that the curved surface receives heat from the barrel. The interface further includes a substantially flat mounting surface and a heat-conducting material disposed between the curved surface and the substantially flat mounting surface to conduct the heat from the curved surface to the substantially flat mounting surface. Moreover, a spring is positioned to be between the interface and the handguard to apply a force to the interface so that the curved surface substantially maintains contact with the barrel. A thermoelectric generator is secured to the substantially flat mounting surface and includes a positive lead and a negative lead.
