A tube is installed, and the lower part of the condenser is installed in parallel with a refrigerant tube having a high ventilation resistance to allow two stages of condensation by the refrigerant tube having a small ventilation resistance and the refrigerant tube having a large ventilation resistance. The present invention relates to a condenser for a heat exchanger having a dual structure to greatly improve the thermal efficiency of the gas.
일반적으로 종래 에어콘의 방열기등으로 이용되는 열교환기의 콘덴서는 양측에 헤더를 구비하고 이 헤더들의 사이에 냉매가 순환되는 냉매튜브와 이 냉매튜브를 따라 냉매가 흐를 때 응축되는 열을 방열시키기 위한 방열핀을 다수 설치하여 구성되어 있으며, 상기 콘덴서에서 응축된 냉매를 증발기로 보내 열교환이 이루어지도록 되어 있었다.In general, a heat exchanger condenser used as a radiator for an air conditioner has a header on both sides, and a heat dissipation fin for radiating heat condensed when the refrigerant flows along the refrigerant tube and the refrigerant circulated between the headers. It is configured to install a number, it was to send the refrigerant condensed in the condenser to the evaporator to be heat exchange.
또, 상기와 같이 구성되는 콘덴서는 양측의 헤더 사이에 압출형의 냉매튜나 관체형상의 냉매순환용 냉매튜브등 일정한 유로폭으로 이루어진 냉매튜브를 설치하도록 되어 있었고, 상기 냉매튜브들의 유로는 전체적으로 동일한 크기로 이루어져 있으며, 상기 냉매튜브의 유로와 헤더를 따라 정해진 패턴으로 냉매가 흐르면서 응축작용을 하도록 구성되어 있었다.In addition, the condenser configured as described above was provided with a refrigerant tube having a constant flow path width such as an extruded refrigerant tube or a tubular refrigerant circulation refrigerant tube between the headers on both sides, and the passages of the refrigerant tubes were the same size as a whole. It consists of, the refrigerant flows in a predetermined pattern along the flow path and the header of the refrigerant tube was configured to condense action.
그러나, 상기와 같은 종래의 것은 상기 콘덴서에 설치되는 상기 냉매튜브들이 동일한 유로크기로써 획일적으로 설치되어 있었기 때문에 상기 냉매튜브의 설치개수만큼의 유로저항을 갖게 되었으며, 상기 냉매튜브의 설치개수에 따른 응축작용만을 하게 되어 콘덴서의 용량을 크게 할 경우에는 냉매튜브의 개수를 늘려야만 하는 폐단이 있었다.However, the conventional method as described above has the flow path resistance as much as the number of installation of the refrigerant tubes because the refrigerant tubes installed in the condenser are uniformly installed with the same flow path size. If only the function of the capacitor to increase the capacity of the closed tube had to increase the number of refrigerant.
따라서, 상기 콘덴서의 용량을 크게 할 경우에는 이 콘덴서의 부피가 용량의 커짐에 비례하여 커질 수 밖에 없는 폐단이 있었으며, 차량의 설치공간에 따른 부피의 제한을 받을 경우에는 상기 콘덴서의 용량을 늘릴 수 없어 효율을 향상시키지 못하는 점 등의 문제점이 있었다.Therefore, when the capacity of the condenser is increased, there is a closed end in which the volume of the condenser is inevitably increased in proportion to the increase in the capacity, and when the volume of the condenser is restricted by the installation space of the vehicle, the capacity of the condenser can be increased. There was a problem such as not improving the efficiency.
