REFRIGERANT JACKET AND AIR CONDITIONING APPARATUS EQUIPPED THEREWITH

摘要

A refrigerant jacket includes a refrigerant cooling member, a cover member and a strength member. The cooling member is constructed of aluminum or aluminum alloy that thermally contacts a heat emitting electrical part, and has a groove portion. A refrigerant tube of a refrigerant circuit fits into the groove portion. The cover member covers the refrigerant cooling member in a state where the refrigerant tube has been fitted into the groove portion. The strength member is higher in strength than the cooling member, and is fixed to the cooling member. The cover member has a cover-side through hole opposing the strength member. The strength member has a cover member fixing screw hole opposing the cover-side through hole. The cover member is fixed to the strength member by a cover member fixing screw that passes through the cover-side through hole and screws into threads of the cover member fixing screw hole.

主权项

1. A refrigerant jacket that uses refrigerant circulating through a refrigerant circuit to cool a heat emitting electrical part, the refrigerant jacket comprising:
a refrigerant cooling member constructed of aluminum or aluminum alloy that thermally contacts the heat emitting electrical part, the refrigerant cooling member having a groove portion formed therein, a refrigerant tube of the refrigerant circuit fitting into the groove portion; a cover member covering the refrigerant cooling member in a state in which the refrigerant tube has been fitted into the groove portion; and a strength member higher in strength than the refrigerant cooling member, the strength member being fixed to the refrigerant cooling member, the cover member having a cover-side through hole formed therein in a position opposing the strength member, the strength member having a cover member fixing screw hole formed therein in a position opposing the cover-side through hole, the cover member fixing screw hole having threads, and the cover member being fastened and fixed to the strength member by a cover member fixing screw that passes through the cover-side through hole and screws into the threads of the cover member fixing screw hole.
