The cooling plate (22) includes a multiplicity of refrigerant ducts (34) with a first duct cross section, the refrigerant ducts being formed between the first and second plate parts (24, 30) in the depressions (32) of the second plate part (30). The cooling plate (22) also includes a distributor portion (42) and a collector portion which each have at least one connection (46) for a refrigerant feed line (56) and a refrigerant return line.
