Title (EN) HEAT EXCHANGER OF REFRIGERATOR
(FR) ÉCHANGEUR DE CHALEUR DE RÉFRIGÉRATEUR
(KO) 냉장고의 열교환기
Abstract: front page image
(EN) A heat exchanger of a refrigerator according to the present invention is a micro-channel type heat exchanger of a refrigerator comprising: a first heat exchanging unit including a plurality of flat tubes for exchanging heat between a refrigerant and air and connected to an inlet pipe through which the refrigerant flows; a second heat exchanging unit including a plurality of flat tubes for exchanging heat between the refrigerant and air, disposed on the outside of the first heat exchanging unit and connected to a discharge tube through which the refrigerant is discharged; and a connection pipe for connecting the first heat exchanging unit and the second heat exchanging unit and supplying the refrigerant discharged from the first heat exchanging unit to the second heat exchanging unit, wherein the first heat exchanging unit is arranged to exchange heat with air that has been heat-exchanged with the second heat exchanging unit, and the sum of the cross sectional areas of the flat tubes of the first heat exchanging unit is larger than the sum of the cross sectional areas of the flat tubes of the second heat exchanging unit.
(FR) L'invention concerne un échangeur de chaleur d'un réfrigérateur qui est un échangeur de chaleur de type à micro-canal d'un réfrigérateur comprenant : une première unité d'échange de chaleur comprenant une pluralité de tubes plats pour échanger de la chaleur entre un fluide frigorigène et de l'air et reliée à un tuyau d'entrée à travers lequel s'écoule le fluide frigorigène ; une seconde unité d'échange de chaleur comprenant une pluralité de tubes plats pour échanger de la chaleur entre le fluide frigorigène et l'air, disposée sur l'extérieur de la première unité d'échange de chaleur et reliée à un tube de décharge à travers lequel le fluide frigorigène est évacué ; et un tuyau de raccordement pour relier la première unité d'échange de chaleur et la seconde unité d'échange de chaleur et fournir le fluide frigorigène évacué de la première unité d'échange de chaleur à la seconde unité d'échange de chaleur, la première unité d'échange de chaleur étant conçue pour échanger de la chaleur avec de l'air dont la chaleur a été échangée avec la seconde unité d'échange de chaleur et la somme des aires en section transversale des tubes plats de la première unité d'échange de chaleur est supérieure à la somme des aires en section transversale des tubes plats de la seconde unité d'échange de chaleur.
(KO) 본 발명에 따른 냉장고의 열교환기는 마이크로 채널 타입으로 구성된 냉장고의 열교환기에 있어서, 냉매 및 공기를 열교환시키는 복수개의 플랫튜브를 포함하고, 냉매가 유입되는 유입관이 연결된 제 1 열교환부, 냉매 및 공기를 열교환시키는 복수개의 플랫튜브를 포함하고, 상기 제 1 열교환부의 외측에 배치되고, 냉매가 토출되는 토출관이 연결된 제 2 열교환부, 상기 제 1 열교환부 및 제 2 열교환부를 연결하고, 상기 제 1 열교환부에서 토출된 냉매를 상기 제 2 열교환부에 공급하는 연결관을 포함하고, 상기 제 1 열교환부는 상기 제 2 열교환부와 열교환된 공기와 열교환되게 배치되고, 상기 제 1 열교환부의 플랫튜브 들의 단면적의 합은 상기 제 2 열교환부의 플랫튜브 들의 단면적의 합 보다 큰 것을 특징으로 한다.
