Outdoor unit of air conditioner

A heat exchanger is configured such that flat tubes 101 in at least two levels bent or connected to each other at one end in an axial direction of the flat tubes and the flat tubes 101 in at least two columns connected to each other are included in refrigerant passages through which refrigerant flows, and a flow direction of gas is counter to flow of refrigerant through the refrigerant passages in a column direction while the heat exchanger serves as a condenser.

Heat exchanger and refrigeration cycle device

PROBLEM TO BE SOLVED: To provide an air-conditioner improved in static pressure efficiency and reduced in noise SOLUTION: The air-conditioner comprises an axial-flow fan 16 disposed in a main body 3 of an indoor or outdoor unit 2, a bell-mouth 28 provided around outer peripheries of blades 14 of the axial-flow fan with an end face of a blowout side opening attached to a fan grill 26, an L-shaped heat exchanger 24 installed over a rear surface and a side surface of the main body, and a chamber 6 located on an opposite side from the side surface and divided by a partition plate 4 from a space 8 in which the axial-flow fan is disposed The bell-mouth 28 is formed so that at least a curvature radius of an inner periphery of an inlet side opening is larger on a partition plate 4 side than on a side of the side surface COPYRIGHT: (C)2006,JPO&NCIPI

Blower and air-conditioner

PROBLEM TO BE SOLVED: To provide an outdoor unit for an air conditioner equipped with a blowoff grille capable of suppressing a pressure loss to blowing wind while using a die with a simple and inexpensive structure in resin integral molding SOLUTION: In the outdoor unit 1 for the air conditioner, a blowoff port 5 for blowing blowoff wind from an axial fan 3 to the outside is provided on a front surface of a casing 2, and a blowoff grille 6 integrally formed of resin material is arranged in the blowoff port 5 A radial lattice 9 composing the blowoff grille 6 has a cross section having an oblong shape along a blowoff direction of the blowoff wind As an upstream side 9A and a downstream side 9B in the blowoff direction are displaced to the rotational direction, this radial lattice 9 with the oblong cross section is formed to have a shape following a swirl flow of the blowoff wind as a whole, when it is seen from the front surface of the unit COPYRIGHT: (C)2010,JPO&INPIT

Outdoor unit for air conditioner

An outdoor unit according to the present invention includes an air-sending-device chamber including a heat exchanger disposed at least on the rear side within an outdoor unit body, a propeller fan having a plurality of blades and disposed on the front side of the heat exchanger, and a bell mouth disposed on the front side of the propeller fan to face an air outlet, a machine chamber in which a compressor is disposed, and a partition plate that separates the air-sending-device chamber and the machine chamber. The partition plate has a protruding shape protruding from the air-sending-device chamber toward the machine chamber. The partition plate has, on the side of the air-sending-device chamber, a recessed area corresponding to the protruding shape. The amount of recess of the recessed area is maximized at a position equal in height to the center of rotation of the propeller fan.

Outdoor unit and refrigeration cycle apparatus including the outdoor unit

PROBLEM TO BE SOLVED: To decrease channel resistance by providing a motor supporting plate for supporting a fan comprising a supply/suction fan and a drive motor for fan between the bottom plate of a housing and the drive motor for fan thereby halving the area of the motor supporting plate when viewed from the front side of an outdoor unit SOLUTION: A motor supporting plate 1 comprises a pair of main plates 2a, 2b and an auxiliary plate 3 wherein the fixing legs 6 of a drive motor 5 for fan are supported by the main plates 2a, 2b, at the upper ends thereof, and fixed to a bottom plate 7 by means of an auxiliary plate 3 A heat exchanger 8 is disposed on the back face side of the bottom plate 7 The motor supporting plate 1 is placed between the drive motor 5 for fan and the bottom plate 7 and not placed between the drive motor 5 and a top plate 10 A specified space is thereby ensured at the upper half in the housing defined by the bottom plate 7, a front plate 9, the top plate 10, and the like, and channel resistance is decreased by halving the occupation area of the motor supporting plate 1 when viewed from the front side of an outdoor unit
