An aspect of a heat exchange unit of a refrigeration cycle device, includes a housing having openings, and gripping members attached to the openings. Each gripping member has a main body having an inner space that opens to an outside, and a plurality of claws that protrude from the main body and that hook to a circumferential edge of the openings. The plurality of claws include a plurality of first claw portions, and at least one second claw portion that is provided on an opposite side to the plurality of first claw portions in a predetermined direction that intersects the opening direction. At least one claw portion out of the plurality of first claw portions and the at least one second claw portion is an elastic claw that is cantilevered by the main body and is elastically deformable in the predetermined direction with respect to the main body.

Heat exchange unit

An outdoor unit of an air-conditioning apparatus includes: a terminal unit that is provided on an outer peripheral surface of a compressor, and electrically connects components provided in the compressor and outside the compressor; a side soundproof cover that covers the outer peripheral surface of the compressor except for the terminal unit; and a terminal cover that covers the terminal unit exposed from the side soundproof cover to the outside of the side soundproof cover, and soundproofs the terminal unit. The terminal cover is attached to the side soundproof cover such that the state of the terminal cover can be changed between a state in which the terminal cover covers the terminal unit and a state in which the terminal cover does not cover the terminal unit.

Outdoor unit of air-conditioning apparatus

A soundproof part that covers a compressor includes a side surface cover including two or more sound absorbing materials and two or more sound insulating materials, and configured to cover a side surface of the compressor. The two or more sound insulating materials include sound insulating materials having different specific gravities. The side surface cover is formed such that one sound absorbing material is disposed adjacent to the compressor, and a sound absorbing material and a sound insulating material are alternately arranged. The side surface cover is also formed such that as a distance from the compressor increases, the sound insulating materials having relatively lower specific gravities are disposed.

Soundproof part and outdoor unit of air-conditioning apparatus

A compressor cover includes a side cover that surrounds a side peripheral surface of a compressor and a top cover provided above the compressor to cover along with the side cover, the compressor. The top cover has a first slope that extends such that an outer peripheral portion of the top cover is located lower than a central portion of the top cover.

Compressor cover, outdoor unit of air-conditioning apparatus, and air-conditioning apparatus

An outdoor unit for an air-conditioning apparatus includes a heat exchanger; a bottom plate; and a separation member configured to separate the bottom plate and the heat exchanger. The bottom plate includes a drainage passage that protrudes downward; and one or more drainage holes each formed to protrude downward from the drainage passage. The drainage passage includes a drainage surface inclined downward toward the one drain hole having a width larger than a width of the heat exchanger. The separation member is formed of a metal electrically less noble than a member forming the heat exchanger, or a resin member. The separation member is provided in the drainage passage and shaped to prevent closing of the drainage passage, in which a height to a surface on which the heat exchanger is placed is larger than a height to an upper surface of the drainage passage.

An outdoor unit for an air conditioning device includes a heat exchanger including (i) heat transfer tubes arranged with a space therebetween and each having one end connected to a refrigerant tube, and (ii) fins extending from the heat transfer tubes; first and second protective members each having (i) a flat plate that covers a respective end portion of the heat transfer tubes and an endmost fin that is located nearest the end portions of the heat transfer tubes, and (ii) a protrusion that protrudes from the flat plate toward the space between the heat transfer tubes near the end portions of the heat transfer tubes; first and second cover members that cover a respective flat plate; and a housing having an inner wall abutting the first cover member and an inner wall abutting the second cover member.

Outdoor unit for air conditioning device

An outdoor unit for an air-conditioning apparatus that includes a bottom plate made of metal, an L-shaped heat exchanger made of metal different than the metal of the bottom plate, a placement plate provided on the bottom plate and having a heat exchanger placement surface on which the heat exchanger is placed. The placement plate having an L-shape in plan view, and the placement plate is held in contact with the bottom plate only below each of a short-side end portion of the placement plate, a long-side end portion of the placement plate, and a corner portion of the placement plate.

An accumulator includes a container, a low pressure refrigerant inlet tube, and a low pressure refrigerant outlet body including an upstream-side tubular section, a low pressure refrigerant turning back section and a downstream-side tubular section in the container. At least a part of the upstream-side tubular section is covered by a first outer tube with a gap between the upstream-side tubular section and the first outer tube, at least a part of the downstream-side tubular section is covered by a second outer tube with a gap between the downstream-side tubular section and the second outer tube, the first outer tube and the second outer tube communicate with each other via a bridging tube, and high pressure refrigerant passes through the gap between the upstream-side tubular section and the first outer tube, the bridging tube, and the gap between the downstream-side tubular section and the second outer tube.
