Abstract

The invention relates to a device for exchanging heat, particularly for use in motor vehicle air-conditioning systems, comprising at least one coolant, at least one coolant inlet (3), and at least one coolant outlet (4), which lead into at least one head pipe (7, 8, 9), whereby the head pipe (7, 8, 9) is divided into at least one inlet section (41′) and into at least one outlet section (42′) by at least one separating element (49). The device for exchanging heat comprises at least one flow-through element (19), which has at least two flow paths situated at least partially parallel to one another, and at least one cross-distributor (10′, 10″, 11′, 11″, 12) via which the flow paths of the flow-through element (19) are fluid-connected so that the inlet section is fluid-connected to the outlet section of the head pipe (7, 8, 9).
