Abstract

Es wird eine Kühlvorrichtung, insbesondere Abgaskühlvorrichtung für eine Verbrennungskraftmaschine vorgeschlagen mit einer Außenschale (31), in der zumindest eine Wärmeübertragungseinheit (27, 28) angeordnet ist, welche ein Außengehäuse (39, 40, 41) aufweist, welches ein zwischen der Außenschale (31) und der Wärmeübertragungseinheit (27, 28) ausgebildeten, von einem Kühlmittel durchströmten Mantel von einem Kanal (21) trennt, der in der Wärmeübertragungseinheit (27, 28) ausgebildet ist und durch den das zu kühlende Fluid strömt, wobei zwischen Außenschale (31) und Außengehäuse (39, 40, 41) der Wärmeübertragungseinheit (27, 28) Stege (29, 30, 34, 35, 36, 37) angeordnet sind, welche im Mantel einen Kühlmittel durchströmten Kanal (33) begrenzen.The invention relates to a cooling device, in particular an exhaust gas cooling device for an internal combustion engine, with an outer shell (31) in which at least one heat transfer unit (27, 28) is arranged, which has an outer housing (39, 40, 41) which extends between the outer shell (31 ) and the heat transfer unit (27, 28) separated by a coolant jacket of a channel (21) which is formed in the heat transfer unit (27, 28) and through which the fluid to be cooled flows, wherein between the outer shell (31) and outer housing (39, 40, 41) of the heat transfer unit (27, 28) webs (29, 30, 34, 35, 36, 37) are arranged, which define in the jacket a coolant flowed through the channel (33).

Erfindungsgemäß sind zwei Wärmeübertragungseinheiten (27, 28) in einer Außenschale (31) angeordnet, zwischen denen Stege (29, 30, 34, 35, 36, 37) derart ausgebildet sind, dass jede der Wärmeübertragungseinheiten (27, 28) im Querschnitt allseitig und mäanderförmig zwangsumströmt ist.

Figure imgaf001
According to the invention two heat transfer units (27, 28) in an outer shell (31) are arranged between which webs (29, 30, 34, 35, 36, 37) are formed such that each of the heat transfer units (27, 28) in cross-section on all sides and meandering forcibly flows around.
