Abstract
A tube-block-type heat transfer device has a tube block consisting of several tubes arranged side-by-side, having spacing elements which are inserted between two adjacent flat tube end areas respectively, and have in each case at least one connection duct along each transverse side of the tube block. The tubes are sealed off on the end side and are provided with transverse openings in their two end areas, which transverse openings are in a connection-duct-forming connection with spacing element transverse openings. At least one pair of separation spacing elements,situated opposite one another in the same space between two tubes have a closed construction so that, on each transverse side of the tube block, at least two mutually separated connection ducts is are formed so that several fluids can flow separately through pertaining tube block sections. The heat transfer device is especially useable as an oil/air cooler for motor vehicles for cooling engine and transmission oil.
