Heat source unit of refrigerating apparatus

摘要

A heat source unit of a refrigerating apparatus includes a heat exchanger, a blower, an electrical component, a rectifying member, and a casing. The casing houses the heat exchanger, blower, electrical component, and rectifying member. The casing has a vent that vents air upward. The electrical component controls driving of an actuator, and includes a heat-generating part and a heat sink. The heat sink is installed on the heat-generating part, and has a heat-radiating fin. The rectifying member extends along a vertical direction, and covers the heat-radiating fin, and rectifies flow of air. An air inlet is formed on a lower part, and an air outlet on an upper part of the rectifying member. A first air flow path is formed inside the rectifying member. An air flow generated by the blower passes through the first air flow path. The heat-radiating fin is positioned in the first air flow path.
