  • Patent number: 10295264
    Abstract: A fluid/air heat exchanging device (2) has fluid-conducting outside collecting chambers (6, 10) having an inlet (8) or outlet (12) and being connected to one another via duct-shaped fluid guides (14) that control the temperature of a fluid flow by an air flow. The air flows in duct-shaped air guides separated from the fluid guides (14). A further collecting chamber (18; 20, 22) is inserted between outside collecting chambers (6, 10). The further collecting chamber (18; 20, 22) is arranged parallel to the outside collecting chambers (6, 10). All the fluid guides (14) are connected to the further collecting chamber and one of the outside collecting chambers (6, 10).

  • Publication number: 20160341482
    Abstract: A heat exchanging device (2), in particular a fluid/air heat exchanger, having individual fluid-conducting collecting chambers (6, 10) which in each case have an inlet (8) or outlet (12) for fluid supply and discharge and which are connected to one another via duct-like fluid guides (14) which control the temperature of, in particular cool, a fluid flow during operation of the device by means of an air flow which flows in duct-like air guides which are separated from the fluid guides (14) in a medium-tight manner, is characterized in that, in order to construct the overall heat exchanging device (2), at least one further collecting chamber (18; 20, 22) is inserted between collecting chambers (6, 10) which are arranged on outer sides which lie opposite one another, which further collecting chamber (18; 20, 22) is arranged parallel to the collecting chambers (6, 10) which lie on the outside, and into which further collecting chamber (18; 20, 22) all the fluid guides (14) which are connected to a collecting cham

  • Patent number: 7740457
    Abstract: A device for delivery of flowable media, especially of lubricants, includes a pump (1) driven by a motor and forming a component of a line system. At least one heating element (21) activated by energy supply is located outside of the housing (3) of the pump (1) in a position enabling heat transfer to the housing (3).

  • Patent number: 7424211
    Abstract: An arrangement for influencing the temperature of flowable media, especially of lubricants found in a lubricant system, has a line through which the medium flow. At least one element (11) is assigned to the line section (1, 5) for influencing the temperature, and can be activated by supplying energy. At least one element (11) is located within the line section (1, 5) in the flow path of the medium. The wall in the line section (1,5) has a connection means (9) for supplying energy to the element (11) located in the line section (1, 5).
