A valve may include a housing forming one inlet and at least one outlet, an operating unit mounted in the housing, and performing expansion or contraction in accordance with a temperature of a flowing working fluid to selectively connect the at least outlet with the one inlet for exhausting the flowing working fluid outside of the housing, wherein the operating unit includes a sliding member slidably inserted into the interior of the housing, a flange member forming a penetration hole and fixedly mounted inside of the sliding member, a rod movably inserted into the penetration hole of the flange member, and a deformable member fixed at the penetration hole of the flange member and expanded or contracted in accordance with a temperature of the flowing working fluid.

Valve

The present invention makes it possible to integrate and control in one circuit the systems, such as electric power components, a driving motor, a stack, and an AC condenser which have the maximum enthalpy under similar operational temperature and use conditions, by using an integrated radiator. Therefore, it is possible to minimize air-through resistance of the radiator for cooling the stack and the electric power components and ensure smooth and stable cooling performance of the stack, electric power components, and AC condenser while improving fuel efficiency by reducing the condensation pressure of the air conditioner. Further, it is possible to improve cooling efficiency by non-repeatedly arranging heat exchangers, and reduce the weight of a vehicle, volume of the parts, and the manufacturing cost, by avoiding using too many parts, such as a radiator, a water pump, and a reservoir tank.

Integrated cooling system for eco-friendly vehicle

A can type of heat exchanger may include a housing formed as a cylinder, having a mounting space at the inside, and formed with at least one inlet and at least one outlet, a heat dissipation unit mounted in the mounting space of the housing, receiving operating fluids from the inlet, and the operating fluids heat-exchanging with each other, a separating plate separating the mounting space and inside of the mounting portion, and a valve unit, selectively opening and closing the mounting space or a bypass passageway separated by the separating plate using linear displacement which is generated when expansion and contraction occur according to the temperature of the coolant flowing from the inlet, and adjusting flow of the operating fluids.

Can-type heat exchanger

A valve for a vehicle provided between a transmission and an oil cooler for cooling transmission oil may include a valve housing in which a first inflow port connected to the transmission and an exhaust port connected to the oil cooler are formed on both sides facing each other and a bypass port connected to the transmission and a second inflow port connected to the oil cooler are formed at a position spaced apart from the first inflow port and the exhaust port along a length direction of the valve housing, and a control unit that is mounted inside the valve housing selectively connects the first inflow port to the exhaust port or the bypass port while expansion or contraction is performed depending on a temperature of the transmission oil, and selectively closes the exhaust port to control a flow stream of the transmission oil.
