Heat exchange device containing heat storage material

摘要

The invention relates to a heat exchange device including at least two tubes (12) for circulating a heat transfer fluid arranged in at least two rows (R1, R2) offset two-by-two from one row to the other. A heat exchange fin (20) and a heat storage tank (22) made from a heat storage material extend transversely to the rows of the tubes (R1, R2) forming a group of tanks and tubes (24) in each instance, wherein a single heat storage tank (22) is in contact with one tube (12) of each row of tubes (R1, R2). The contact with the tubes (12) takes place alternately on two opposing walls (26, 28) of the heat storage tank (22), and the walls (26, 28) are also in contact with fins (20). The invention can be used for the air-conditioning evaporators of automobiles.

主权项

1. A heat exchange device comprising at least two tubes (12) for the circulation of a heat transfer fluid (F1), a heat exchange fin (20), and a heat storage reservoir (22) of a heat storage material (F2), the tubes (12) and the heat storage reservoir (22) forming a reservoir-tubes group (24),
wherein the tubes (12) are arranged along at least two rows of tubes (R1, R2) and have two large opposite surfaces (16,18) extending perpendicularly to the extension direction of the rows of tubes (R1, R2) and constituting a fin contact surface and a reservoir contact surface, respectively, and in that the heat storage reservoir (22) extends transversely to the rows of tubes (R1, R2) and is in contact with a tube (12) of each row of tubes (R1, R2), the contact with the tubes (12) being carried out alternately on a first wall (26) of the heat storage reservoir (22) and on a second wall (28) of the heat storage reservoir (22) opposite the first wall (26).
