摘要： The invention relates to a heat exchanger with inter-connecting cells in a row or block which evenly distribute and transfer heat to a fluid within a cell. Voids between rows or blocks of cells and the heat transfer medium comprise additional means of transferring heat from a heat-transfer medium to the fluid within the cells. The heat exchanger may be used but not limited to applications such as a condenser in an air conditioning unit, a wall heater or an indirect evaporative cooler.

摘要： The present disclosure relates to an outdoor unit of an air conditioner. The outdoor unit of the air conditioner according to the present disclosure includes: a cabinet including perimeter surfaces disposed vertically in four directions, respectively, and an upper surface disposed on an upper side thereof that is perpendicular to each of the perimeter surfaces, with suction ports and a discharge port, the suction ports being formed in two surfaces that are formed in a first direction and a second direction opposite to each other and one surface that is formed in a third direction perpendicular to the first direction and the second direction, respectively, among the perimeter surfaces, and the discharge port being formed in the upper surface; a heat exchanger disposed inside the cabinet where the suction ports are formed to exchange heat between air introduced into the cabinet and a refrigerant; an air blowing fan disposed inside the cabinet where the discharge port is formed to allow the air that is heat-exchanged by the heat exchanger to flow toward the discharge port; and an orifice disposed along an outer circumference of the air blowing fan, while being spaced apart from the air blowing fan, to form a flow path of the air flowing by the air blowing fan, wherein the orifice includes: a narrowing portion into which the air flowing inside the cabinet is introduced, with the flow path therein having a cross-sectional area that decreases in an air flow direction; a maintaining portion disposed downstream of the narrowing portion, with the flow path therein having a cross-sectional area that is maintained in the air flow direction; and an expanding portion disposed downstream of the maintaining portion, with the flow path therein having a cross-sectional area that increases in the air flow direction, and the maintaining portion has a height that decreases from a fourth direction opposite to the third direction toward the third direction along a circumferential surface of the orifice.

摘要： An outdoor unit for an air conditioner and a housing of the outdoor unit are disclosed. The housing includes a cabinet body, a side-by-side door and a door-latching assembly. The side-by-side door is used to open and close the cabinet body, and includes a first door body and a second door body which are opened side by side. The door-latching assembly includes a cabinet-locking member provided on the cabinet body, a door-locking member provided on the first door body and a latch member provided on the second door body. The latch member is movable with respect to the second door body between a locked position where the latch member cooperates with both the cabinet-locking member and the door-locking member in a locked manner and an unlocked position wherein the latch member is separated from both the cabinet-locking member and the door-locking member.

摘要： A subcooler is made up of a plate type heat exchanger. The accumulator is located between a compressor and the subcooler in a width direction of an outdoor unit in a planar view. The subcooler overlaps with the accumulator in the width direction in the planar view. As a result, a compact heat pump can be provided when the subcooler is a plate type heat exchanger.
