Abstract
Each of the first outdoor heat exchanger and the second outdoor heat exchanger includes a body including a stacked structure in which refrigerant pipes and fins are alternately stacked in a direction perpendicular to a thickness direction in which airflow passes through the first outdoor heat exchanger or the second outdoor heat exchanger. Each refrigerant pipe internally defines a plurality of refrigerant flow paths arranged in the thickness direction. A first header pipe connects the refrigerant flow paths in each refrigerant pipe to one another at a first end of the body in a length direction of the refrigerant pipes. A second header pipe connects the refrigerant flow paths in each refrigerant pipe to one another at a second end of the body in the length direction of the refrigerant pipes.
Claims7
An air conditioner for a railway vehicle, the air conditioner comprising:
- a first heat exchanger and a second heat exchanger facing each other;
- and
- a blower located between the first heat exchanger and the second heat exchanger and configured to generate airflow passing through the first heat exchanger and the second heat exchanger,
- each of the first heat exchanger and the second heat exchanger including
- a body including a stacked structure in which refrigerant pipes and fins are alternately stacked in a direction perpendicular to a thickness direction in which the airflow passes through the first heat exchanger or the second heat exchanger, each of the refrigerant pipes internally defining a plurality of refrigerant flow paths, the plurality of refrigerant flow paths in each of the refrigerant pipes being arranged in the thickness direction,
- a first header pipe located at a first end of the body in a length direction of the refrigerant pipes, the first header pipe connecting the plurality of refrigerant flow paths in each of the refrigerant pipes to one another at the first end, and
- a second header pipe located at a second end of the body in the length direction of the refrigerant pipes, the second header pipe directly connecting, entirely within a flow path in the second header pipe, the plurality of refrigerant flow paths in all of the refrigerant pipes to one another at the second end, wherein
- the first header pipe of the first heat exchanger has an inlet through which a refrigerant to be used by the first heat exchanger for heat exchange flows in, and an outlet through which the refrigerant used by the first heat exchanger for the heat exchange flows out,
- the first header pipe of the second heat exchanger has an inlet through which a refrigerant to be used by the second heat exchanger for heat exchange flows in, and an outlet through which the refrigerant used by the second heat exchanger for the heat exchange flows out, and
- the first header pipe of the first heat exchanger and the first header pipe of the second heat exchanger face each other.
