ABSTRACT:
The present invention relates to a portable heat transfer apparatus designed to supply heat to an external heat load, such as a space-heating unit or a heating garment, in a manner to be usable in outdoor and other environments where it is difficult to receive a supply of electricity or fuel gas, and allows a ratio of LPG and air to be controlled so as to perform combustion in desirable conditions.The portable heat transfer apparatus of the present invention is adapted to ignite a mixture supplied from a fuel-gas supply unit and a fuel gas-air air-fuel unit having air-fuel ratio adjustment mechanism, using a piezoelectric ignition unit, so as to induce a flame burning in a combustion chamber of a burner, and drive a heat-drive pump disposed relative to burner while interposing a heat-collecting container therebetween, by heat generated from the flame burning, so as to transfer heat to an external heat load, while controlling the air-fuel ratio adjustment mechanism by using a spring-type timer adapted to be moved by a control lever, or by activating the air-fuel ratio adjusting temperature sensor installed in the heat-collecting container.
