PORTABLE HEAT TRANSFER DEVICE Russian patent published in 2010 - IPC F24H1/06 

FIELD: heating.

SUBSTANCE: portable heat transfer device, according to the present invention, is intended to ignite mixture supplied by unit of fuel gas supply and gas-air and fuel-air unit, having mechanism that controls air-fuel ratio, using unit of piezoelectric ignition to generate flame in burner combustion chamber and control of heat pump relative to burner. At the same time heat-accumulating container is arranged between them. Heat-accumulating container receives it from heat produced by burning flame in order to sent heat to external heat load. At the same time air-fuel ratio adjustment mechanism is controlled with the help of spring-type timer adapted to move under action of control lever or by activation of temperature sensor installed in heat-accumulating container.

EFFECT: arrangement of heat transfer device makes it possible to control air and fuel ratio in order to burn mixture in combustion chamber, under required conditions.
