Abstract

A thermal management module for a thermal management system is disclosed. The thermal management module includes a first heat exchanger for flowing through by a refrigerant and by a working medium fluidically separately with respect to the refrigerant. A second heat exchanger is provided including at least a first fluid path and at least a second fluid path, separate from the first fluid path, respectively for flowing through by the refrigerant. A connecting arrangement is arranged between the first heat exchanger and the second heat exchanger. The connecting arrangement connects the first heat exchanger and the second heat exchanger to one another mechanically and fluidically, so that the refrigerant can flow between the first heat exchanger and the second heat exchanger.
