Abstract:
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.
Abstract:
A vehicle radiator may include a first header tank partitioned through a first barrier rib that is integrally formed at the inside to store a coolant to form a first chamber and a second chamber inside the first header tank, a second header tank disposed apart by a predetermined gap from the first header tank and partitioned through a second barrier rib that is integrally formed therein to correspond to the first barrier rib to form a third chamber and a fourth chamber, a plurality of first and second tubes that are mounted in a vertical direction at each separated position of each inside surface of the first header tank and the second header tank, heat diffusion fins, each of which are formed between the first tubes and the second tubes; and a condenser that is provided at the inside of the fourth chamber in the second header tank.
Abstract:
The invention relates to a ball valve (1) having an internal seal arrangement, particularly for use in motor vehicle refrigerant circuits, having an actuator (2), a shaft (3) with shaft bearing (5), a ball (4) with a ball passage channel (16) as well as a valve housing (13) with refrigerant connections (15), characterised in that the ball (4) has a floating bearing in the valve housing (13) and that the ball (4) is arranged between two ball sealing seats (9) for this purpose, wherein one ball sealing seat (9) is positively supported by the valve housing (13) and towards which a sealed bearing is provided by a sealing seat ring (10) and that a second ball sealing seat (9) is positively supported by a closure part (17) on the opposite side of the valve housing (13) and towards which a sealed bearing is provided by a sealing seat seal (10), wherein the closure part (17) has a sealed bearing towards the valve housing (13) by means of a closure part seal (22).
Abstract:
A cooling system for a vehicle that system includes a radiator disposed in a front of the vehicle, and introduced with cooling water thereinto to cool the cooling water through heat exchange with exterior air;. In addition, a first condenser is disposed at a first side of the radiator in a width direction of the vehicle and connected with the radiator via a cooling water pipe to be introduced with the cooling water, and introduced with refrigerant via a refrigerant pipe to condense the refrigerant through heat exchange with the cooling water therein. A second condenser is interconnected with the first condenser via the refrigerant pipe to be introduced with the refrigerant condensed by the first condenser, and disposed in a front of the radiator to additionally condense the refrigerant through mutual heat exchange of the exterior air introduced while driving the vehicle and the refrigerant.
Abstract:
A tube for use in a heat exchanger comprises a first portion spaced apart from a second portion. At least one reinforcing structure having a non-circular cross-sectional shape extends between the first portion and the second portion to divide a flow of a fluid through the tube into a first flow channel to one side of the at least one reinforcing structure and a second flow channel to a second side of the at least one reinforcing structure. A fluid communication channel provides fluid communication between the first flow channel and the second flow channel. The fluid communication channel is at least one of a) formed through the at least one reinforcing structure and b) formed between two adjacent ones of the reinforcing structures.
Abstract:
An air conditioning system for motor vehicles includes a temperature door configured to adjust an opening degree of a hot air path, a PTC heater configured to heat an air introduced into the hot air path, and a control unit configured to control an opening position of the temperature door with respect to the hot air path and to secure a minimum opening degree of the hot air path, so that a minimum amount of air is blown toward the PTC heater regardless of the opening position of the temperature door. The control unit is configured to actively adjust the minimum opening degree of the hot air path depending on an on/off condition of the PTC heater.
