PORTABLE HEAT-TRANSFER DEVICE Russian patent published in 2009 - IPC F24H1/06 

FIELD: physics.

SUBSTANCE: invention is meant for heat exchange and can be used for transferring heat to different objects. The heat-transfer device has apparatus for producing and supplying a mixture of fuel gas and air, and a heating unit. The heating unit comprises heat-accumulating jacket and a burner, inside the heat-accumulating jacket and made with a combustion chamber with a flat surface. The burner has several openings, each of which lies on its upper side along the current, reaches the said flat surface and serves as the opening of the burner, meant for injecting the mixture into the combustion chamber and, and a porous solid component. The porous solid component, which converts heat into radiated heat, bounds the region of the surface of the combustion chamber, lying opposite the front of the flame, obtained near the said flat surface and a heat-actuated pump, connected to the heat-accumulation jacket and capable of receiving heat through the heat-accumulating jacket. The heat-accumulating jacket has such a shape that, it surrounds the burner, at a distance from it, leaving space between the said burner and said jacket, and has several openings, which are part of the heat-exchange section lying up along the current and the heat-exchange section lying lower along the current. The heat-accumulating jacket can exchange heat when gas coming out of the combustion chamber passes through heat-exchange section lying lower along the current, and can transfer the received heat such that, it can be used for heating the said mixture in the said heat-exchange section lying up along the current and for heating the said heat-actuated pump.

EFFECT: invention provides for a compact device, its easier transportation, stable quality of burning and reduced loss of heat to the surrounding medium.
