A heat exchanger assembly includes a header extending in a longitudinal direction, a plurality of heat transfer tubes aligned along the longitudinal direction of the header and connected to the header, a plurality of fins secured to the heat transfer tubes, a first corrective member and a second corrective member. The first corrective member extends along the longitudinal direction of the header on a downstream side of the heat transfer tubes or the header along a direction of an air flow. The second corrective member extends along the longitudinal direction of the header on an upstream side of the heat transfer tubes or the header along the direction of the air flow. A sandwiched object is at least any one of the heat transfer tubes, the fins, and the header. The sandwiched object is sandwiched by the first and second corrective members.

Heat exchanger assembly and outdoor unit of refrigerating apparatus

An outdoor unit of a refrigeration apparatus includes a heat exchanger, a casing constituent member and a seal member. The heat exchanger has plural collection header pipes, plural fins disposed at a predetermined fin pitch between the header pipes, and plural heat transfer tubes inserted through the fins and connected to the header pipes. An interstice larger than the fin pitch is formed between one of the header pipes and one of the fins adjacent to the one of the header pipes. The casing constituent member is disposed facing the one of the header pipes and is configured to surround part of the heat exchanger. The seal member is attached to the casing constituent member, is pressed against the one of the header pipes and the one of the fins in the environ of the interstice facing the casing constituent members, becomes deformed, and closes the interstice.

Outdoor unit of refrigeration apparatus

An air conditioner includes a printed circuit board to which a power device is attached; and a refrigerant jacket which is connected to the power device, and through which refrigerant used for a refrigeration cycle flows. The printed circuit board is accommodated in a switch box. The refrigerant jacket is fixed to the switch box through a heat transfer plate, and the refrigerant jacket and the printed circuit board are connected together by the switch box.
