Abstract
A flange, and a pipe and a flange structure and, more particularly, to a pipe and a flange structure, which allows the pipe connection and the assembling of an expansion valve of a vehicle air conditioner using two or more evaporators.
Claims14
A pipe and flange structure comprising a flange for connecting an expansion valve and a pipe that transfers a refrigerant to an evaporator with each other, wherein the flange includes:
- a body;
- a supply passage including a first inlet and a first outlet, wherein the first inlet is formed at one end and the first outlet is formed at another end thereof for a refrigerant to be introduced from the expansion valve and supplied to the evaporator;
- a discharge passage including a second inlet and a second outlet, wherein the second inlet is formed at one end and the second outlet is formed at another end thereof for the refrigerant to be introduced from the evaporator and supplied to the expansion valve,
- the first inlet and the second outlet, connected to the expansion valve, are positioned on one surface of the body to be parallel to each other, and
- the first outlet and the second inlet are formed on the remaining surfaces except the one surface, but among the surfaces facing each other, the first outlet is formed on one surface and the second inlet is formed on the other surface,
- wherein the pipe connecting the flange and the evaporator with each other is divided into two or more pipes in the pipe and flange structure, and a first fixing part and a second fixing part fixed to each other by a fixing means are respectively positioned at connection portions of the two or more pipes.

A flange comprising:
- a body;
- two or more passages passing through the inside of the body;
- and
- a fluid inlet and a fluid outlet respectively positioned at ends of each of the two or more passages,
- wherein the inlet and outlet of each of the two or more passages are positioned on different surfaces of the body,
- wherein the two or more passages include one supply passage and one discharge passage,
- the supply passage includes a first inlet which is the fluid inlet and a first outlet which is the fluid outlet, and the first inlet is formed at one end and the first outlet is formed at another end thereof, and the discharge passage includes a second inlet which is the fluid inlet and a second outlet which is the fluid outlet and the second inlet is formed at one end and the second outlet is formed at another end thereof,
- the first inlet and the second outlet are positioned on one surface of the body to be parallel to each other, and
- the first outlet and the second inlet are positioned on the remaining surfaces of the body other than the one surface,
- the flange further comprising:
- an extension part in which a predetermined region corresponding to the first outlet or the second inlet protrudes from the body;
- and
- a coupling part positioned on the extension part,
- wherein the coupling part protrudes from the extension part in a direction in which the first outlet or the second inlet is positioned.
