Heat exchanger

摘要

A heat exchanger (28) has a first inlet (29) and a first outlet (30), which are fluidically connected with one another via a first path (31) carrying for a first medium to be cooled. A second inlet (32) and a second outlet (33) are fluidically connected with one another via a second path (34) carrying a second medium. A third inlet (35) and a third outlet (36) are fluidically connected with one another via a third path (37) carrying a third medium. The first path (31) is coupled with the second path (34) and with the third path (37) in a heat-transferring manner and in such as way that the media are separated. The heat-transferring coupling between the first path and the second path takes place upstream of the heat-transferring coupling between the first path and the third path relative to the direction of flow of the first medium.

1. A heat exchanger comprising:
a first inlet and a first outlet for a first medium to be cooled, the first inlet and first outlet being fluidically connected with one another via a first path carrying the first medium; a second inlet and a second outlet for a second medium to be heated, the second inlet and the second outlet being fluidically connected with one another via a second path carrying the second medium; and a third inlet and a third outlet for a third medium to be heated, the third inlet and the third outlet being fluidically connected with one another via a third path carrying the third medium, wherein: the first path is coupled with the second path and with the third path in a heat-transferring manner and such that the media are separated from one another; the heat-transferring coupling between the first path and the second path takes place upstream of the heat-transferring coupling between the first path and the third path in relation to a direction of flow of the first medium; a fourth path for carrying the first medium, the fourth path bypassing the heat-transferring couplings of the first path with the second path and the first path with the third path, the fourth path fluidically connecting the first inlet with the first outlet; and a control for controlling the flow of the first medium in the first path and the fourth path; a common housing has the first inlet and first outlet, the second inlet and the second outlet and the third inlet and the third outlet and contains the first path, the second path, the third path and the fourth path.
