Heat exchanger for motor vehicle, has pipes with maeander-shaped moldings and connected directly to block, where pipes are soldered with one another at contact points and are shifted against each other

The exchanger (1) has pipes (3) e.g. multi-chamber pipes, which form flow channels for a medium e.g. cooling agent, and exhibit an outer surface overflowing of another medium such as air. The pipes exhibit maeander-shaped moldings and are connected directly to a block (2). The moldings on the outer...

Summary:The exchanger (1) has pipes (3) e.g. multi-chamber pipes, which form flow channels for a medium e.g. cooling agent, and exhibit an outer surface overflowing of another medium such as air. The pipes exhibit maeander-shaped moldings and are connected directly to a block (2). The moldings on the outer surface form contact points (9), by which the pipes are connected with each other. The pipes are soldered with one another at the contact points and are shifted against each other. The pipes exhibit pipe ends, which flow into collecting cases (4, 5). Die Erfindung betrifft einen Wärmeübertrager (1) mit Rohren (3), die Strömungskanäle für ein erstes Medium bilden und eine äußere, von einem zweiten Medium, vorzugsweise Luft überströmbare Oberfläche aufweisen. Es wird vorgeschlagen, dass die Rohre (3) mäanderförmige Ausformungen aufweisen und direkt zu einem Block (2) verbunden sind.
