Abstract: Provided is an outdoor unit for a refrigeration apparatus, the outdoor unit being capable of suppressing decrease in reliability. An outdoor unit (10) includes: a compressor (12); an outdoor fan (18) configured to provide outdoor air flows (AF), the outdoor fan (18) being higher in heightwise position than the compressor (12); a high-heat generating electric component (65) configured to control the compressor (12); a fan controlling electric component (66) configured to control the outdoor fan (18); a board unit (75) including a compressor controlling electric component mount portion (75a) and a fan controlling electric component mount portion (75b); a first cooling unit (80); and an outdoor unit casing (40). The outdoor air flows (AF) flow from below upward in the outdoor unit casing (40), and flow out of the outdoor unit casing (40) through a blow-out port (402).

Abstract: An outdoor unit for a refrigeration apparatus includes: a casing that houses a plurality of devices including a first device and a second device; a plurality of electric components including a first electric component and a second electric component; an electric component box disposed in the casing and that houses the plurality of electric components; a first wire that carries a first voltage or current between the first electric component and the first device; a second wire that carries a second voltage or current between the second electric component and the second device; and a cover part that suppresses entry of liquid into the electric component box. The second voltage or current is lower than the first voltage or current.

Abstract: An outdoor unit for a refrigeration apparatus includes: a fan that provides an air flow; a casing that houses the fan and that includes a blow-out port through which the air flow is blown; a first heat generating component that generates heat when being energized; a first board on which the first heat generating component is mounted; an electric component box that houses the first board; and a first cooler that cools the first heat generating component and that includes: a heat pipe in which a coolant is sealed and that is thermally connected to the first heat generating component; first heat radiating fins on a flow path of the air flow and that exchange heat with the air flow; and a main body interposed between the heat pipe and the first heat radiating fins to thermally connect the heat pipe to the first heat radiating fins.
