Patent number: 4678026Abstract: A water/air cooler is provided for water cooled internal combustion engines, especially for use in vehicles, which is constructed out of a cooler block held between water tanks and lateral parts. The lateral parts are connected with the water tanks by means of laterally overextending and gripping fastening brackets. These fastening brackets exhibit openings for engaging protruding connecting bolts on the water tanks. The brackets are affixed to the connecting bolts either through spring clamps or through corresponding protrusions having elastic clamping devices themselves. This water/air cooler is very easily assembled and is especially adapted for systems wherein the water tanks are manufactured out of plastic material.Type: GrantFiled: August 5, 1985Date of Patent: July 7, 1987Assignee: Suddeutsche Kuhlerfabrik Julius Fr Behr GmbH & Co.Inventors: Werner Lenz, Manfred Most

Patent number: 4540044Abstract: A radiator arrangement for water cooled combustion engines is disclosed, especially for use with commercial vehicles. The radiator cooling block, including the water boxes, are fastened at the vehicle frame by means of lateral support parts. The lateral support parts are provided with lateral mounting flanges which respectively extend over both ends of the water boxes and exhibit bores which are aligned with corresponding bores at the water boxes, whereby cotter pins or the like extending through the bores act as connecting pins to connect the parts together. This arrangement exhibits the advantage that the water boxes themselves are used as connecting traverse elements for the lateral support parts so that the lateral support parts and the water boxes form a stable frame construction which holds the soldered cooling block therebetween. Expensive soldered connections for the fastening of the lateral support parts is disposed with and the necessary reinforcing strength is formed by this frame construction.Type: GrantFiled: January 25, 1984Date of Patent: September 10, 1985Assignee: Sueddeutsche Kuehlerfabrik Julius Fr.
