Abstract

See full text

A heat exchanger is provided that includes a first flow channel for a refrigerant, a second flow channel for a refrigerant, and a third flow channel for a coolant, wherein the first flow channel has a first region for initial cooling of the refrigerant and a second region for further cooling of the refrigerant. The refrigerant can flow in a high-pressure phase in the first flow channel and the refrigerant can flow in a low-pressure phase in the second flow channel. A first heat exchange occurs between the refrigerant in the first region of the first flow channel and the coolant in the third flow channel and a second heat exchange occurs between the refrigerant in the second region of the first flow channel and the refrigerant in the second flow channel.
