Abstract: A refrigerant compressor according to an exemplary aspect of the present disclosure includes, among other things, a cooling jacket including a plurality of perforations configured to cause refrigerant flowing through the perforations to form impingement jets and further configured to direct the impingement jets onto a surface adjacent a stator. The refrigerant compressor may be used in a heating, ventilation, and air conditioning (HVAC) chiller system, for example.
