摘要:
The invention relates to a heating or air conditioning system for a motor vehicle, comprising a housing (1) which is composed of several housing segments (2, 3, 4, 5). According to the invention, at least one housing segment is embodied as an insert part (5) which is inserted into the remaining housing (2, 3, 4) exclusively after said remaining housing (2, 3, 4) is mounted in the motor vehicle. The insert part comprises at least one functional module.

The invention pertains to a stationary vehicle air conditioning system with a refrigerant circuit, in which at least one compressor circulates the refrigerant to at least two condensers. The at least one compressor may be powered by the vehicle's mechanical power, by an electrical source, or by a combination of these driving forces. Depending on desired operating characteristics, the condensers may be arranged in a series or parallel configuration. A second compressor also may be added, which second compressor may be powered by a source other than the mechanical energy of the vehicle's engine.

The invention pertains to a stationary vehicle air conditioning system with a refrigerant circuit, in which a compressor circulates refrigerant through a refrigerant circuit including at least one condenser. The one compressor may be powered by the vehicle's mechanical power, by an electrical source, or by a combination of these driving forces. Depending on desired operating characteristics, a plurality of condensers may be arranged in a series or parallel configuration within the circuit, and a second compressor also may be added, which second compressor may be powered by a source other than the mechanical energy of the vehicle's engine. A plurality of fans may be positioned and selectively operable to provide cooling air streams to one or more of the condensers, with the vehicle engine mechanically driving one fan and an electrical power source driving another fan. At minimum, at least one fan is provided to provide a cooling air stream to one or more condensers, wherein the fan is a hybrid drive unit that is capable of being driven through mechanical or electrical means.

A flap provided with an integral motor-containing drive element provided with an integral motor-containing drive element for controlling the air flow through an air-guide duct in, for example, a motor vehicle air condition system which includes a housing defining an air flow duct, an evaporator located in the housing, a heater located in the housing. The flap is adapted to be pivoted about and axis and is supported at each of its axial ends. One end is provided with a cut-out or recess which extends inwardly from one end along the axis of rotation. This cut-out or recess has opposed edges which engage in slots formed in holding means or housing that encloses the drive element, and which permit the ready insertion of the drive unit into an operative position.

This invention concerns a control valve for a ventilation system of an automobile, with at least one edge over which air flows, which can be moved from at least a first into at least a second position. The control valve as per the invention is mainly two-dimensional and has in particular a changing cross-sectional profile in the area of the overflowed edge. Due to this cross-sectional profile, at least one sub area of the overflowing air is diverted into a number of flow directions deviating from the main flow direction.

An assembly configuration for devices for exchanging heat, having at least a first device for exchanging heat, having at least an inlet for a first fluid medium, a header and/or distributor tube for the first fluid medium, a plurality of first flow-through devices for the first fluid medium, a header and at least an outlet for the first fluid medium, and further, adjacent the first device for exchanging heat, at least a second device for exchanging heat having at least an inlet for a second fluid medium, a header and/or distributor tube for the second fluid medium, a plurality of flow-through devices for the second fluid medium, and at least an outlet for the second fluid medium.
摘要:
A heat exchange arrangement for a vehicle has at least two heat exchangers exposed to the action of ambient air. One of the heat exchanger is coolant cooler and the other one is a charge-air coolant. Each of these coolers has tubes through which liquid or gas flows and heat dissipating ribs connected to the tubes. The coolant cooler is positioned upstream of the charge-air cooler in the air-flow direction. The charge-air cooler has an overlapping region in which the coolant cooler and the charge-air cooler overlap one another and a non-overlapping region in which the coolant cooler projects substantially perpendicularly to the cooling air flow direction. The non-overlapping region is formed at least in the charge-air outlet region and is cooled directly by ambient cooling air. The overlapping region is cooled by the ambient cooling air that has passed through the coolant cooler, which is positioned immediately upstream of the overlapping region of the charge-air cooler.

The invention relates to a heat exchanger unit comprising tubes, ribs and a lateral section containing reinforcement ribs, in addition to a method for producing said unit.
摘要:
A heat exchanger for cooling exhaust gas, around which liquid cooling medium flows on the outside, including a bundle of rectangular tubes provided as ducts for the exhaust gas whose ends are welded into tube bottoms. The bundle of rectangular tubes is surrounded with a sheet metal jacket which follows the contour of the bundle and which is provided with a cooling medium inlet and a cooling medium outlet. The ends of the sheet metal jacket are provided with welded-on flange plates which are each open by means of a central opening with respect to the bundle of rectangular tubes and which are provided with fastening devices for fastening onto pipe sections of an exhaust pipe.
