  • Publication number: 20210018232
    Abstract: An outdoor heat exchanger includes: a main heat exchange area; a sub heat exchange area; and a connecting pipe and a connecting pipe interconnecting the main heat exchange area and the sub heat exchange area. The main heat exchange area has a main heat exchange channel and a main heat exchange channel. The sub heat exchange area has a sub heat exchange channel, a sub heat exchange channel, and a sub heat exchange channel. The connecting pipe connects the sub heat exchange channel and the sub heat exchange channel to the main heat exchange channel while the sub heat exchange channels are joined together. The connecting pipe interconnects the sub heat exchange channel and the main heat exchange channel.

  • Publication number: 20200217590
    Abstract: In a heat exchanger, each of a plurality of heat exchange members includes: a main body portion including a heat transfer pipe; and extending portions provided to the main body. The extending portions extend from ends of the main body portion in a third direction. When a dimension of the main body portion in the third direction is represented by La, a dimension of the extending portions in the third direction is represented by Lf, a dimension of a wall thickness of each of the heat transfer pipes is represented by tp, and a thickness dimension of each of the extending portions is represented by Tf, relationships: Lf/La?1 and Tf?tp are satisfied.

  • Publication number: 20200166253
    Abstract: Provided is a heat exchanger, including: a refrigerant distributor including: a gas-liquid separating portion having a function of separating a gas-liquid refrigerant mixture into a liquid refrigerant and a gas refrigerant; and a distributing portion provided to the gas-liquid separating portion. A plurality of heat transfer pipes connected to the distributing portion. The plurality of heat transfer pipes are arranged side by side in a first direction, and extend along a second direction intersecting with the first direction. When the refrigerant distributor is viewed along a direction orthogonal to each of the first direction and the second direction, a first space forming portion overlaps a region of the plurality of heat transfer pipes. When the refrigerant distributor and the heat transfer pipes are viewed along the first direction, a clearance is present between the gas-liquid separating portion and the heat transfer pipes.

  • Publication number: 20200149818
    Abstract: In a heat exchanger, each of a plurality of heat exchange members includes: a flat pipe; and a heat transfer plate integrated with the flat pipe along a longitudinal direction of the flat pipe. A width direction of each of the flat pipes intersects with a direction in which the plurality of heat exchange members are arranged side by side. Each of the heat transfer plates includes an extending portion extending outward in the width direction of each of the flat pipes from at least one of one end of a corresponding one of the flat pipes in the width direction and another end of the corresponding one of the flat pipes in the width direction. Each of the flat pipes has one or more flat pipe bent portions, each forming a groove extending along the longitudinal direction of the flat pipes.

  • Patent number: 4399179
    Abstract: A polyester laminated film which comprises a transparent layer and delustered layer(s) laminated at least on one side face of the transparent layer is provided. The transparent layer is formed by a biaxially stretched polyester film mainly composed of polyethylene terephthalate, while the delustered layer is made of an at least uniaxially stretched polyester film which is mainly composed of a polyethylene terephthalate copolymer containing, as a copolymer composition, 1 to 20 mole % of ##STR1## wherein n is an integer from 2 to 140, and x represents ##STR2## and which also contains inert inorganic particles of 0.3 to 20 microns at 3 to 40% by weight.The film of the present invention as described above is roughened on the surface, and is superior in the writability and transcribability by pencils, ink, indian ink, etc., with an excellent transparency, and therefore, very useful for tracing films and the like.
