Outdoor heat exchanger and air conditioner including the same

摘要

An outdoor heat exchanger in cooling operation includes: a first header pipe into which a refrigerant compressed by a compressor flows; a first heat exchanging unit connected with the first header pipe and allowing a refrigerant to exchange heat with the air; a bypass pipe through which the refrigerant exchanging heat in the first heat exchanging unit flows; a first distribution pipe connected with the bypass pipe; a distribution pipe check valve that is disposed in the first distribution pipe and preventing the refrigerant exchanging heat in the first heat exchanging unit from passing through the first distribution pipe; a second header pipe into which the refrigerant passing through the bypass pipe flows; a second heat exchanging unit connected with the second header pipe and allowing a refrigerant to exchange heat with the air; and a second distribution pipe through which the refrigerant exchanging heat in the second heat exchanging unit passes.

1. An outdoor heat exchanger that operates as a condenser in cooling operation and as an evaporator in heating operation in an air conditioner, the outdoor heat exchanger comprising:
a first header pipe into which a refrigerant compressed by a compressor flows in cooling operation; a first heat exchanging unit connected with the first header pipe and allowing a refrigerant to exchange heat with the air; a bypass pipe through which the refrigerant exchanging heat in the first heat exchanging unit flows in cooling operation; a first distribution pipe connected with the bypass pipe; a first distributor to connect the first heat exchanging unit with the first distribution pipe; a distribution pipe check valve that is disposed in the first distribution pipe and preventing the refrigerant exchanging heat in the first heat exchanging unit from passing through the first distribution pipe in cooling operation; a second header pipe into which the refrigerant passing through the bypass pipe flows in cooling operation; a second heat exchanging unit connected with the second header pipe and allowing a refrigerant to exchange heat with the air; a second distribution pipe through which the refrigerant exchanging heat in the second heat exchanging unit passes in cooling operation, and a second distributor to connect the second heat exchanging unit with the second distribution pipe, wherein the first heat exchanging unit is composed of a plurality of refrigerant tubes and a plurality of thermal conducting fins, wherein one side of each of the refrigerant tubes of the first heat exchanging unit converge on the first header pipe and the other side of each of the refrigerant tubes of the first heat exchanging unit converge on the first distributor, wherein the second heat exchanging unit is composed of a plurality of refrigerant tubes and a plurality of thermal conducting fins, wherein one side of each of the refrigerant tubes of the second heat exchanging unit converge on the second header pipe and the other side of each of the refrigerant tubes of the second heat exchanging unit converge on the second distributor.
