(EN) HEAT-EXCHANGER HEADER AND HEAT EXCHANGER PROVIDED THEREWITH
(FR) COLLECTEUR D'ÉCHANGEUR DE CHALEUR ET ÉCHANGEUR DE CHALEUR LE COMPORTANT
Abstract
(EN)
Provided are: a heat-exchanger header that can reduce pressure losses, can distribute a refrigerant evenly without causing the heat-transfer performance of the heat exchanger to decrease, and has a simple structure; and a heat exchanger provided with said heat-exchanger header. This heat-exchanger header (10, 20) is used in a heat exchanger in which a refrigerant is run in parallel through a plurality of heat-transfer tubes (30) laid out in parallel. A plurality of through-holes (12) to which one end of each of the plurality of heat-transfer tubes is attached are lined up in the header in the lengthwise direction thereof. At least one chamber (10A) that connects to the plurality of through-holes, forming a refrigerant channel, is formed in the header. Each of the plurality of through-holes is either an entrance-side through-hole or an exit-side through-hole to which either the refrigerant-entrance-side end or the refrigerant-exit-side end of one of the plurality of heat-transfer tubes is attached. A plurality of grooves (14) that extend in the lengthwise direction of the header are formed, in the widthwise direction perpendicular to said lengthwise direction, in the parts of the abovementioned chamber facing the entrance-side through-holes.

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.
