  • Patent number: 9599413
    Abstract: A heat exchanger, in particular an intercooler, is provided that includes at least one collector box that has a base. At least one tube engages into a passage in an approximately perpendicular manner with respect to the base, the passage protruding out of the base and surrounding a tube end, and the passage has a rectangular cross-section that is adapted to the outer circumference of the tube. The aim of the invention is to further extend the service life of the heat exchanger with a further reduction of the wall thickness of the collector box base as well as of the tube. This is achieved in that a wall thickness of the passage is thinned at least in a corner region.

  • Patent number: 9528781
    Abstract: An anti-microbial heat transfer apparatus comprises a hybrid coil with multiple rows of fins and tubes. The fins and tubes have an upper portion and a lower portion. The upper portion comprises fins that include copper and has a height that is different than the height of the second portion. A chilled medium inside the tubes makes the surface of the fins and tubes colder than the temperature of the dew point of the surrounding air such that a condensate is formed on the surface of the fins. Gravity causes the condensate to drip copper ions from the upper portion to the lower portion of the coil resulting in the inhibition of microbial growth on the coil.
