Heat exchange device and drive unit for a motor vehicle

摘要

A heat exchange device having a first media channel for a first medium and a second media channel for a second medium is further refined in that, in at least one section of the heat exchange device, a third media channel for a transfer medium is arranged between the first media channel and the second media channel, so that the heat transfer from the first medium to the second medium takes place via the transfer medium.

主权项

1. A heat exchange device having:
a first media channel for a first medium, a second media channel for a second medium, a third media channel for a transfer medium arranged in a first section of the heat exchange device between the first media channel and the second media channel, so that, in said first section, a heat transfer from the first medium to the second medium takes place via the transfer medium, whereas, in a second section, a heat transfer from the first medium to the second medium takes place directly, and a plurality of plates, wherein:
the first medium is provided as an exothermic medium, and the second medium is provided as an endothermic medium,each of the second media channel and the third media channel is formed in one of the plurality of plates, andthe plate that forms the third media channel is smaller than the plate that forms the second media channel, so that, in said first section of the heat exchange device, the exothermic medium flows around the plate that forms the third media channel and, in said second section, the exothermic medium flows around the plate that forms the second media channel.
