An air conditioning piping system of the disclosure includes a refrigerant pipe made of a plastic material and configured to provide a fluid flow between components constituting an air conditioning system; at least one connection flange made of the plastic material and configured to provide a connection between the refrigerant pipe and components constituting the air conditioner system; and at least one charging port made of the plastic material and having a charging valve configured to inject a refrigerant into the refrigerant pipe.

Air conditioner piping system and method of producing the same

A piping system for an air conditioner that includes a refrigerant pipe that is formed of a plastic material and has a multi-layered pipe structure including an outer layer and an inner layer. The piping system provides a fluid flow between parts constituting the air conditioner system. A first flange formed of the plastic material and providing a connection between the refrigerant pipe and components constituting the air conditioner system. A second flange formed of the plastic material and connected to a charging valve for injecting a refrigerant into the refrigerant pipe.

Piping system for air conditioner

A plate-type heat exchanger including a body plate, an upper plate, and a lower plate. The body plate includes a plurality of alternately stacked plates, a space between the plurality of plates having a first heat exchange passage through which a first refrigerant of high temperature and high pressure flows, and a second heat exchange passage through which a second refrigerant of low temperature and low pressure flows. A heat exchange between the first refrigerant and the second refrigerant is performed in the body plate. The upper plate is bonded to a front side of the body plate and having a first inlet hole through which the first refrigerant is introduced and a first outlet hole through which the second refrigerant is discharged. The lower plate is bonded to a rear side of the body plate and having a second inlet hole through which the second refrigerant is introduced and a second outlet hole through which the first refrigerant is discharged.

Plate-type heat exchanger and air conditioning system for vehicle having the same

A double-pipe heat exchanger including a heat exchange pipe and an integrated connector. The heat exchange pipe may include an inner pipe forming a first flow path, and an outer pipe accommodating the inner pipe therein and forming a second flow path outside the inner pipe. The integrated connector may include a main body including, at one side thereof, a heat exchange pipe engaging part with which one end of the heat exchange pipe is combined, a first connector flow path portion formed to be connected to the first flow path and discharging a first fluid flowing from the first flow path to an outside of the main body, and a second connector flow path portion formed to be connected to the second flow path and supplying a second fluid from the outside of the main body to the second flow path.

Double-pipe heat exchanger including integrated connector

A brake hose comprising according to the disclosure may include: a tube-shaped inner rubber layer filled with a brake fluid; and a first reinforcing fiber layer, an intermediate rubber layer, a second reinforcing layer, and an outer rubber layer, which sequentially surround an outer circumferential surface of the inner rubber layer, wherein the first reinforcing fiber layer has a structure in which a plurality of layers of butyl rubber, which is a material having a high loss factor, are stacked on a PET fiber to improve vibration insulating performance, and various exemplary embodiments may be possible.
