1. A stationary scroll plate for use in a scroll compressor, the stationary scroll plate comprising:
a base plate having a first side and a second side, wherein the second side opposes the first side;
a spiral wrap formed at the first side of the base plate, wherein the spiral wrap is adapted to interact with a corresponding spiral wrap of an orbiting scroll plate to form a compression chamber;
an injection channel formed within the base plate, the injection channel providing an injection path for injection of fluid into the compression chamber;
a recess located at the second side, wherein the recess is configured to form an intermediate pressure cavity that comprises a connection to an opening in the base plate arranged within the spiral wrap;
an insert placed within the recess, wherein the insert separates a volume within the recess into-forms a cooling chamber within the recess and a remaining volume for forming the intermediate pressure cavity;
an inlet channel via which the cooling chamber is connected to the injection channel; and
an outlet channel via which the cooling chamber is connected to the inside of the spiral wrap.
