SYSTEM AND APPARATUS FOR HEATING OR COOLING HAVING FLUID COOLED ELECTRONICS

摘要

A refrigeration unit is disclosed that includes a fluid cooled power electronics package. The refrigeration unit can include a variable speed motor used to drive a compressor. The variable speed motor is driven by the fluid cooled power electronics where the fluid used to cool the electronics is working fluid from the refrigeration cycle of the refrigeration unit. A conduit is configured to route cooling fluid to the electronics. In one embodiment the electronics can be removed without the need to disassemble the conduit that carries the cooling fluid to the power electronics.

主权项

1. A system for heating or cooling a conditioned space comprising:
an outdoor unit including a housing having a plurality of vent openings structured to admit a flow of air, a refrigerant coil within the housing for conveying refrigerant fluid to exchange heat with the air, and a compressor in fluid communication with the refrigerant coil and having an electric compressor motor; the outdoor unit further including a power electronics unit structured to drive the electric compressor motor, and a refrigerant conduit in fluid communication within the housing with at least one of the refrigerant coil and the compressor; the housing further having therein a first internal space where the refrigerant coil and compressor are positioned and in fluid communication with the plurality of vent openings, a second internal space where the power electronics unit is positioned, and a through space extending between the first and second internal spaces; the refrigerant conduit extending between the first internal space and the second internal space via the through space, and including a cooling segment in thermal contact with the power electronics unit; and a clamping mechanism having a clamped state holding the cooling segment against the power electronics unit so as to maintain the thermal contact, and a release state where the power electronics unit can be decoupled from the refrigerant conduit.
