  • VENTILATION UNIT FOR A MOTOR VEHICLE
    Publication number: 20050124285
    Abstract: A ventilation unit for a motor vehicle is provided comprising a housing with air ducts for supplying air through panel openings into the interior of the vehicle. At least one draft tube is disposed in the housing adjacent said panel openings, where the at least one draft tube includes an outlet slot arranged to be exposed to the air stream exiting the panel openings. The draft created by the air stream crossing over the slot draws hot air from the interior of the draft tube to be mixed with the exiting air stream. The amount of drafting created by the air stream depends on the velocity of the exiting airflow. This relationship in turn makes the ventilation unit of the present invention perform as a passive device.

  • Heat exchanger and a method for producing a heat exchanger
    Patent number: 6899168
    Abstract: A heat exchanger is assembled in a simple and cost-effective way and needs a relatively low space requirement. According to the invention, the tubes (11) are expanded at the tube ends (16) in such a way that the tube ends (16) are of rectangular design in cross section. The tube ends (16) have parallel long connecting surfaces (18) which are brought into bearing contact with long connecting surfaces (18) of adjacent tube ends (16). Furthermore, the tube ends (16) have short connecting surfaces (22), onto which the collecting tanks (23, 29) are placed with their legs (24, 25) or collars (30, 31). A space-saving heat exchanger can be produced in a simple way by soldering the long connecting surfaces (18) together, on the one hand, and by soldering the short connecting surfaces (22) to the collecting tanks (23, 29), on the other hand.

  • Air conditioning system and operating method for a motor vehicle with heat pump and/or reheat operating mode
    Patent number: 6843312
    Abstract: An air conditioning system has a refrigerant cycle, a coolant cycle, a refrigerant/coolant heat exchanger, coupling these cycles so as to transfer heat, and a valve for operating mode-dependent control of the refrigerant flow, whereby the air conditioning system can be operated not only in air conditioning mode but also in a heat pump or reheat mode. An internal combustion engine exhaust gas/coolant heat exchanger is connected upstream in series to the refrigerant/coolant heat exchanger in the coolant cycle in the heat pump mode; and/or in the reheat operating mode the refrigerant/coolant heat exchanger functions as a condenser/gas cooler, connected upstream in series on the coolant side to the supply air/coolant heat exchanger. In addition or as an alternative, a drying operating mode can be provided for drying the supply air/refrigerant heat exchanger with reversed air conveying direction.

  • Plate-type heat exchanger
    Publication number: 20040194939
    Abstract: The invention relates to a plate-type heat exchanger having a plate block comprising partition plates which delimit flow channel layers between the plates. According to the invention, the partition plates have a solid or folded edge, which projects out of the plane of at least one main side of the partition plates at the edge side, along closed-edge regions which are spaced apart from one another in the peripheral direction by means of intervening open-edge regions. In the plate block, this solid or folded edge is joined in a fluid-tight manner to the opposite edge region of an adjoining partition plate and functions as a lateral boundary for the associated flow channel layer. Such heat exchangers may be used, for example, in automobiles and reactors of fuel cell systems.
