Pump unit

Abstract

The refrigerant circulation device includes a primary flow path, a secondary flow path, a heat exchanger, a frame, a power connector, two inlets, and two outlets. The primary flow path allows for the flow of primary refrigerant. The secondary flow path allows for the flow of secondary refrigerant. The heat exchanger is connected to both the primary and secondary flow paths. The frame has two first outer surfaces extending along a first direction when viewed from above, and two second outer surfaces extending along a second direction intersecting the first direction, and houses the primary flow path, secondary flow path, and heat exchanger. The power connector is located on and protrudes from the first outer surface. The two inlets are located on the first outer surface where the power connector is located and communicate with the primary and secondary flow paths. The two outlets are located on the first outer surface where the power connector is located and communicate with the primary and secondary flow paths.
