HOT BLAST HEATER WITH A HOLLOW HEAT PIPE IN WHICH AN ELECTRIC HEATER IS EMBEDDED, CAPABLE OF IMPROVING HEAT TRANSFER EFFICIENCY BY FORMING A HEAT TRANSFER MEMBER INTO A HONEYCOMB STRUCTURE

摘要

PURPOSE: A hot blast heater with a hollow heat pipe in which an electric heater is embedded is provided to transfer heat at the velocity of sound by delivering a vaporized heat medium in a vacuum state.;CONSTITUTION: A hot blast heater with a hollow heat pipe comprises a heat generating and transmitting unit(110) which comprises a hollow pipe tube with an electric heater(112) and a heat transfer member(113). The hollow heat pipe comprises an external part and an internal part. A sealed space is formed between external and internal parts. A heat medium and the electric heater are installed in the space. The lower front part of the external part is upwardly inclined so that the heat medium smoothly circulates by gravity. The heat transfer member is installed in a hollow portion formed by the internal part and effectively emits heat generated from the hollow heat pipe tube to the outside.;COPYRIGHT KIPO 2013
