  • Publication number: 20240033841
    Abstract: A device (16) and method for determining the wave height (H) of a solder wave (42) formed from liquid solder (41) and conveyed by a solder nozzle assembly (12) is provided. The device includes a resiliently flexible film body (18) for floating placement on the solder wave (42) and a measuring unit (38) for determining the position of the surface of the film body (18) floating on the solder wave relative to a reference point (39). The device has an evaluation unit (44) for determining the wave height (H) depending on the position of the film body (18). A wave soldering machine is also provided.

  • Patent number: 10081069
    Abstract: A device for soldering electrical or electronic components on a printed circuit board includes a soldering nozzle arrangement arranged above a solder crucible. The nozzle arrangement includes at least one carrier, on which at least one soldering nozzle is arranged. Molten solder is conveyed, using a conveyor unit, out of the solder crucible through the soldering nozzle to the components to be soldered. At least one discharge unit is arranged between a tip of the soldering nozzle and the carrier for any excess solder that has left the soldering nozzle. The discharge unit includes at least one baffle plate substantially surrounding the soldering nozzle.

  • Patent number: 9574449
    Abstract: An internally coolable component for a gas turbine with at least one cooling duct, on the inner surface of which swirl elements are arranged in the form of turbulators which extend transversely with respect to the main flow direction of a coolant is provided. In order to reduce pressure losses for the coolant in the cooling duct, pins with different heights are set up between the turbulators.

  • Patent number: 8616015
    Abstract: A cooling circuit for removing waste heat from a cooling device of an electromechanical converter is provided. The cooling circuit includes a chilling medium, a cooler for extracting heat from the chilling medium, a return connecting the cooling device of the converter to the cooler and conducts warm chilling medium, a feed connecting the cooler to the cooling device of the converter and conducts cool chilling medium, and an absorption chiller for extracting heat from the chilling medium. The absorption chiller is driven by the heat of the warm chilling medium that is in the return.
