Abstract: A device for cooling a fluid to be compressed in a compressor, in particular a refrigerant, with a heat carrier fluid. The device has at least one first flow channel for guiding the fluid, at least one second flow channel for guiding the heat carrier fluid and an inlet and an outlet for the heat carrier fluid.

Abstract: A cooler includes two substantially parallel flow chambers and three substantially parallel plates, two of the plates forming a substantially planar structure at the outer sides of the cooler, and the intermediate plate, which is interposed between the two planar plates, being shaped such that a fluid flow is divided into a plurality of flows after entering the cooler, which preferably actively flows on one of the two sides of the cooler but always flows on both sides simultaneously.

Abstract: A heat exchanger with at least one plate includes main dimples between which secondary dimples are formed which are flatter and/or smaller with respect to their dimensions as seen in a plan view. A depth of the secondary dimples may be at most 0.5 times a channel height and/or at most 0.5 times the depth of the main dimples.

Abstract: A heat exchanger includes at least one plate, which heat exchanger or plate can be mounted on a battery module of an electric vehicle, and a plurality of at least partially parallel channels for the evaporation of refrigerant are formed in a plane parallel to the plate and are branched from at least one common inlet and/or outlet.
