Abstract:
Disclosed herein is an air conditioner for a vehicle which includes a sealing member having a first sealing part for sealing a space between a flange of inlet and outlet pipes of an evaporator and a pipe penetration part of an air-conditioning case and a second sealing part for sealing a space between a dash panel of the vehicle and an outer face of the air-conditioning case, thereby simplifying an assembling process and reducing manufacturing costs by reducing the number of components for sealing of the pipe penetration part and minimizing vibration and noise transferred from an engine room side of the vehicle to the air-conditioning case.
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.
Abstract:
The invention relates to a motor vehicle air conditioning system having a plurality of control dampers, the control dampers being designed as at least one cold air damper and at least one warm air damper for controlling a cold air path and a warm air path, which system is characterized in that a passage for a partial air flow can be formed between the control dampers depending on the damper position, and in that the passage forms additional air flow resistance for the cold air flow, thereby increasing the linearity of flow control of the cold air flow and the warm air flow.
Abstract:
A variable displacement compressor includes a rotary valve coupled to a drive shaft of the compressor and configured to selectively permit fluid communication between a suction chamber and cylinders of the compressor. An annular seal is disposed adjacent the rotary valve and engages at least a portion of a wall defining the suction chamber and a surface of the rotary valve.
Abstract:
The present invention relates to the heat exchanger 1 of refrigerant circuitry of an air-conditioning system for a vehicle, which enables a bidirectional pass flow. The air-conditioning system is configured to perform a combined operation of cooling device mode and heat pump mode, the heat exchanger 1 is formed in the form of a multi-pass, and the flow direction of a refrigerant varies depending on operation mode. The first heat exchanger 1 formed in the form of a multi-pass includes header pipes 2 and 3, flow paths assigned to respective passes, and means configured to partition an internal volume space of one or more header pipes 2 and 3 into independent regions. A first pass of the heat exchanger 1 has a greater flow cross section and greater heat exchange surface than the last pass.
Abstract:
A heat pump system for a vehicle having a complex valve device including a three-way valve, an on-off valve, expansion means and connection blocks are formed integrally with one another, the three-way valve part being connected to the refrigerant circulation line of an inlet of the exterior heat exchanger such that the refrigerant selectively bypasses the exterior heat exchanger, the on-off valve part being connected to an inlet of the bypass line to open and close the bypass line. Connection blocks connect the three-way valve part and the on-off valve part with the refrigerant circulation line of an outlet of the exterior heat exchanger to communicate with each other. Expansion means are connected to an inlet of the three-way valve part to selectively expand refrigerant discharged from an interior heat exchanger. All functions of the heat pump system are thus conducted through a refrigerant control of the complex valve device.
Abstract:
A heat exchanger inlet tank including a housing having an inner surface and an outer surface and an inlet connector having an inner surface substantially continuous with the inner surface of the housing. The inner surface of the inlet connector and the inner surface of the housing converging to form an inlet interface. The heat exchanger further includes a protuberance disposed on the inner surface of the housing configured to militate against a pressure drop of a fluid flowing through the inlet tank.
Abstract:
The present invention relates to an infrared sensor assembly for measuring temperature in a vehicle, including: a support bracket 3 configured to be detachably coupled with an inner surface of a garnish on one side inside the vehicle to form a base; a casing 5 configured to be detachably coupled on the support bracket 3 and form an inner installation space between the support bracket 3 and the casing 5; a main PCB 7 configured to be inserted into a PCB housing 17 so as to be interposed between the support bracket 3 and the casing 5; and an infrared sensor 9 configured to be inclinedly bound with the main PCB 7 to measure the temperature in the vehicle. By this configuration, the overall size of the infrared sensor assembly may be compacted, the infrared sensor assembly may be easily commonly used in different types of vehicles, and the infrared sensor assembly may be embedded in a garnish of an interior material, such as an A-pillar to improve an aesthetic of the interior of the vehicle.
Abstract:
Disclosed herein is a heat exchanger in a vehicle including a supply manifold which supplies fluid introduced from the outside while distributing the fluid to first and second cooling units. The first and second cooling units cool the fluid supplied from the supply manifold by heat exchange action. A first return manifold collects and discharges the fluid discharged from the first cooling unit and a second return manifold collects and discharges the fluid discharged from the second cooling unit.
Abstract:
A method of bending a tube arrangement including an inner tube disposed within an outer tube is performed using a bending die having a concave groove including a curved portion extending around a peripheral surface of the bending die, the curved portion of the concave groove having at least one ridge projecting therefrom. The tube arrangement is located within the concave groove and a force is applied to the tube arrangement in a direction toward the curved portion of the bending die to cause the tube arrangement to conform to the shape of the concave groove. The at least one ridge projecting from the concave groove causes the outer tube to deform such that an interior surface of the outer tube contacts an exterior surface of the inner tube, securing a position of the inner tube within the outer tube.
