Abstract
A power electronics unit, a vapor compression system incorporating the power electronics unit, and a method of cooling a power electronics unit are provided. The power electronics unit includes a semiconductor portion and an inductor portion. Approximately 80% of the heat generated by the power electronics unit may be derived from the semiconductor portion. Approximately 20% of the heat generated by the power electronics unit may be derived from the inductor portion. The semiconductor portion is cooled using at least one fan. The inductor portion is cooled using a working fluid (e.g., a refrigerant). The working fluid may be provided from upstream of the evaporator in the vapor compression system. Limiting the use working fluid to only cool the inductor portion of the power electronics unit may minimize the impact of the power electronics unit on the vapor compression system.
