The present invention relates to an internal heat exchanger double-tube structure of an air conditioning system having an alternative refrigerant applied thereto, wherein the double tube is provided with a vortex-forming dimple structure, thereby improving the heat exchange performance, and the structure is indispensably applied to an air conditioning system that needs to use an alternative refrigerant, thereby improving the performance thereof. The present invention provides an internal heat exchanger double-tube structure of an air conditioning system having an alternative refrigerant applied thereto, the internal heat exchanger double-tube structure being configured to exchange heat between a low-temperature/low-pressure refrigerant discharged from an evaporator and a high-temperature/high-pressure refrigerant discharged from a condenser, the internal heat exchanger double-tube structure comprising: an inner pipe having a channel through which the low-temperature/low-pressure refrigerant discharged from the evaporator flows; and an outer pipe surrounding the inner pipe and having a channel through which the high-temperature/high-pressure refrigerant discharged from the condenser flows, wherein the inner pipe is configured to have a helical groove such that a channel is formed along the outer peripheral surface thereof, and the helical groove is provided in a vortex-forming concave groove type on the inside thereof and along the longitudinal direction thereof such that the vortex-forming concave groove type generates a vortex in the refrigerant that flows through the channel.

    La présente invention concerne une structure à double tube d'échangeur de chaleur interne d'un système de climatisation auquel est appliqué un fluide frigorigène alternatif, le double tube étant pourvu d'une structure d'alvéole formant un tourbillon, ce qui permet d'améliorer les performances d'échange de chaleur, et la structure est appliquée de manière non distribuée à un système de climatisation qui doit utiliser un fluide frigorigène alternatif, ce qui améliore ses performances. La présente invention concerne une structure à double tube d'échangeur de chaleur interne d'un système de climatisation auquel est appliqué un fluide frigorigène alternatif, la structure à double tube d'échangeur de chaleur interne étant conçue pour échanger de la chaleur entre un fluide frigorigène basse température/basse pression évacué par un évaporateur et un fluide frigorigène haute température/haute pression évacué par un condenseur, la structure à double tube d'échangeur de chaleur interne comprenant : un tuyau interne ayant un canal à travers lequel s'écoule le fluide frigorigène basse température/basse pression évacué par l'évaporateur; et un tuyau externe entourant le tuyau interne et ayant un canal à travers lequel s'écoule le fluide frigorigène haute température/haute pression évacué par le condenseur, le tuyau interne étant conçu pour avoir une rainure hélicoïdale de telle sorte qu'un canal est formé le long de sa surface périphérique externe, et la rainure hélicoïdale est ménagée de manière à se présenter sous la forme d'une rainure concave formant un tourbillon sur son intérieur et le long de sa direction longitudinale de telle sorte que la rainure concave formant un tourbillon génère un tourbillon dans le fluide frigorigène qui s'écoule à travers le canal.

    본 발명은 이중관에 와류형성 딤플 구조를 제공하여 열교환 성능을 향상함과 아울러, 대체냉매를 사용해야 하는 공조시스템에서 필수적으로 적용되어 성능향상을 높일 수 있도록 하는 대체냉매적용 공조시스템의 내부 열교환기용 이중관 구조에 관한 것이다. 본 발명은 증발기에서 배출된 저온/저압의 냉매와 응축기에서 배출된 고온/고압의 냉매를 상호 열교환하기 위한 내부 열교환기 이중관 구조로서, 상기 증발기에서 배출된 저온/저압의 냉매가 흐르는 유로를 갖는 내부 파이프와; 상기 내부 파이프를 감싸면서 상기 응축기에서 배출된 고온/고압의 냉매가 흐르는 유로를 갖는 외부 파이프를 포함하고, 상기 내부 파이프는 외주면을 따라 유로를 형성하도록 하는 나선형 홈을 가지도록 이루어지되, 상기 나선형 홈은 그 길이방향을 따라 내측으로 와류형성용 오목홈 형태로서, 상기 와류형성용 오목홈 형태에 의해 유로를 흐르는 냉매에 소용돌이가 발생하도록 이루어짐을 특징으로 하는 대체냉매적용 공조시스템의 내부 열교환기 이중관 구조를 개시한다.
