Provided is an air conditioner system for a vehicle. The air conditioner system for a vehicle includes a compressor, an integral condenser in which a water cooling region and an air cooling region are formed integrally with each other, an expansion valve, and an evaporator, wherein the water cooling region and the air cooling region of the integral condenser are formed on one plate, such that existing air cooling and water cooling condensers may be formed integrally with each other through one-time brazing coupling, thereby reducing a package and simplifying assembling and manufacturing processes.

Abstract: Heat exchanger, in particular condenser, comprises two parallel end closing plates (1, 2) having made a coolant inlet and outlet and at least one inlet and an outlet of the refrigerant. A heat exchange unit is provided between the closing plates (1, 2) and at least one coolant compartment and at least one refrigerant compartment, separated by an inner plate (5). The coolant compartments and, refrigerant compartments are arranged alternately and connected such that they form together with said inlets and outlets separated hydraulic circuits for the coolant and refrigerant and a turbulator panel (3, 4) is arranged in each of the compartments (3, 4). The turbulator panels (3) of the refrigerant circuit comprise on their surface first disturbing elements (9) the shape of which is matched to the physical properties of the gaseous refrigerant, and which determine the height of the turbulator panel of the refrigerant circuit, while the turbulator panels (4) of the coolant circuit comprise on their surface second disturbing elements (10) the shape of which is matched to the physical properties of the liquid coolant which determine the height of the turbulator panel of the coolant circuit, wherein the shape of the first disturbing elements (9) is different from the shape of the second disturbing elements (10). The shape of the turbulator panels (3, 4) is matched to the independent optimal managing, slowing down and disturbing of the refrigerant and the coolant, while ensuring a low pressure drop of their flow to achieve a high heat exchange coefficient.

A brazed heat exchanger, for example a heat exchanger to be used in an air-conditioning system, preferably as a condenser, includes flat tubes extending between a pair of header tubes and fins arranged between the flat tubes. The components are produced from aluminum alloys, and are brazed together using an AlSi braze alloy. The aluminum alloys have a zinc content of no greater than 0.5% before brazing, and zinc from the aluminum alloys diffuses into the braze joints to result in braze joints having an average zinc content of no greater than 0.1%.

A cooling module including a first heat exchanger cooling a first heat exchange medium, a second heat exchanger cooling a second heat exchange medium, a third heat exchanger cooling a third heat exchange medium, and a fan and shroud assembly arranged in parallel in an air flow direction, wherein a flow of the first heat exchange medium inside first tubes forming the first heat exchanger is perpendicular to a flow of the second heat exchange medium inside second tubes forming the second heat exchanger and parallel with a flow of the third heat exchange medium inside third tubes forming the third heat exchanger. The cooling module capable of sufficiently securing the first heat exchange medium condensing performance, the third heat exchange medium cooling performance, and the second heat exchange medium cooling performance and being miniaturized.

A tube used in a heat exchanger, wherein a tube body includes a curved end portion, a pair of parallel portions, a pair of inclination portions, and a fixed portion in which a long end part extending from one of the pair of inclination portions is bent to hold therebetween a short end part extending from the other of the pair of inclination portions, and the tube is a pipe member having a flattened shape in cross-section. Poor brazing is reduced by making the inclination angle of at least part of the other inclination portion with respect to the flat plate portion larger than that of the one inclination portion.

The present invention relates to a heat exchanger for a motor vehicle provided on the front surface of an engine room of the vehicle, and, more particularly, to a heat exchanger for a motor vehicle including a sealing member provided on the circumference of the heat exchanger in order to prevent driving-induced wind from leaking to the outside of the heat exchanger without passing through the heat exchanger.

A radiator-intercooler integrated module and a vehicle including the same are provided. The radiator-intercooler integrated module includes a low-temperature radiator and a water cooled intercooler of the vehicle which are integrated into a single body.

A heat exchanger having multiple segments is described. The heat exchanger includes a pair of manifolds, having tubes extending therein. Further, a first blocking element is provided in a manifold to divide the tubes into a first set of tubes and a second set of tubes having a fluid communication with each other. Further, a second blocking element is provided in the manifold, corresponding to the second set of tubes, to further divide the second set of tubes into a first segment of tubes and a second segment of tubes. Further, an inlet is provided on the manifold to introduce the heat exchange fluid to the first set of tubes. Further, a plurality of outlets provided on the manifold to receive the heat exchange fluid from the second set of tubes.

A heat exchanger includes fins each housed in a respective one of tubes. Each of the fins includes a connecting portion that corrugated for a predetermined fin pitch and that has peaks joined to an inner surface of a wall of each of the tubes and a non-connecting portion that is not joined to the inner surface of the wall of the each of the tubes. The non-connecting portion has a length longer than the predetermined fin pitch. The wall of the each of the tubes has a protrusion to face the non-connecting portion.

An active seal arrangement operably connected to a radiator and condenser of a vehicle. The arrangement includes at least one movable seal. The seal is selectively movable between a closed, air-restricting position and an open, air-passing position. The seal is slidably attached to a side wall fitted between the radiator and the condenser. A position controller operably connected to at least one sensor regulates the position of the seal.
