(EN) HEAT-EXCHANGER HEADER AND HEAT EXCHANGER PROVIDED THEREWITH
(FR) COLLECTEUR D'ÉCHANGEUR DE CHALEUR ET ÉCHANGEUR DE CHALEUR LE COMPORTANT
Abstract
(EN) A heat exchanger header for a heat exchanger in which refrigerant is flowed in parallel through a plurality of flat tubes 30 disposed in parallel includes a header main body 11 in which a plurality of through-holes 12 to which ends of the plurality of flat tubes 30 are connected are arranged side by side in a longitudinal direction, and a lid body 13 that faces the plurality of through-holes 12 of the header main body 11 and is joined to the header main body 11. At least one chamber communicating with the plurality of through-holes 12 and serving as a refrigerant flow passage is formed between the header main body 11 and the lid body 13. Each of the plurality of through-holes 12 is an inlet side through-hole or an outlet side through-hole to which a refrigerant inlet side end or a refrigerant outlet side end of the plurality of flat tubes 30 is connected. In a part of the lid body 13 that faces the inlet side through-holes, a plurality of grooves extending in the longitudinal direction of the lid body 13 are formed in a lateral direction perpendicular to the longitudinal direction.
(FR) L'invention porte sur : un collecteur d'échangeur de chaleur qui peut réduire des pertes de pression, qui peut répartir de façon régulière un réfrigérant sans provoquer la diminution des performances de transfert de chaleur de l'échangeur de chaleur, et qui a une structure simple; et un échangeur de chaleur comportant ledit collecteur d'échangeur de chaleur. Ce collecteur d'échangeur de chaleur (10, 20) est utilisé dans un échangeur de chaleur dans lequel un réfrigérant circule en parallèle à travers une pluralité de tubes de transfert de chaleur (30) disposés en parallèle. Une pluralité de trous traversants (12) auxquels est attachée une extrémité de chacun de la pluralité de tubes de transfert de chaleur sont alignés dans le collecteur dans la direction de la longueur de celui-ci. Au moins une chambre (10A) qui est reliée à la pluralité de trous traversants, formant un canal de réfrigérant, est formée dans le collecteur. Chacun de la pluralité de trous traversants est soit un trou traversant côté entrée soit un trou traversant côté sortie, vers lequel soit l'extrémité côté entrée de réfrigérant soit l'extrémité côté sortie de réfrigérant de l'un de la pluralité de tubes de transfert est attachée. Une pluralité de rainures (14) qui s'étendent dans la direction de la longueur du collecteur sont formées, dans la direction de la largeur perpendiculaire à ladite direction de la longueur, dans les parties de la chambre mentionnée ci-dessus faisant face aux trous traversants côté entrée.
