Description

히트파이프를 이용한 냉온풍기{THE AIRCONDITIONER WITH HEAT PIPE}Cold air blower using heat pipe {THE AIRCONDITIONER WITH HEAT PIPE}

본 고안은 히트파이프를 이용한 냉온풍기에 관한 것이다.The present invention relates to a cold and hot air fan using a heat pipe.

종래의 온풍기는 연탄, 석유와 같은 연료를 사용하여 따뜻한 공기를 제공하였는데, 이들 연료는 연소효율이 낮을 뿐 아니라 연소시 유해가스가 배출되어 대기를 오염시킨다. 또한 종래의 냉방기는 냉매로 오존층을 파괴하는 프레온 가스를 주로 사용하므로 환경을 파괴하는 단점이 있었다.Conventional hot air heaters use fuels such as briquettes and petroleum to provide warm air. These fuels not only have low combustion efficiency, but also emit harmful gases during combustion to pollute the atmosphere. In addition, since the conventional air conditioner mainly uses a freon gas that destroys the ozone layer as a refrigerant, there is a disadvantage of destroying the environment.

그러므로 새로운 소재의 개발이 요구되면서 히트파이프가 부상하고 있다. 히트파이프는 액체가 기체로 바뀌는 증발과 반대로 기체가 액체로 응축될 때 흡수 및 방출되는 잠열을 이용하여 대량의 열을 이동시키는 열전달 기구로서 열전도율이 뛰어나 연료사용량을 절감시키고, 사용 수명이 긴 장점을 가진다.Therefore, heat pipes are emerging as the development of new materials is required. Heat pipe is a heat transfer mechanism that transfers a large amount of heat by using latent heat absorbed and released when gas is condensed into liquid, as opposed to evaporation of liquid into gas. Heat pipe has excellent thermal conductivity and reduces fuel consumption and has a long service life. Have

상기와 같은 장점으로 인해 히트파이프를 이용한 냉난방 기술이 개발되고 있다.Due to the advantages described above, a heating and cooling technology using a heat pipe has been developed.

It is disclosed that the radiator using the heat transfer pipe configured by injecting and sealing the heat conducting medium in a high vacuum state made up of a condensation unit formed by vertically disposing the branch pipe introduced into the furnace, but has a disadvantage in that only warm air is provided.
