Claims (4)

1. Radiator (10, 10', 10") für einen elektrischen Transformator mit zwei mit einer Mehrzahl von Sicken (15) versehenen Blechen (11, 12), die durch Schweißungen (17, 17', 17") in den Sicken (15) miteinander verbunden sind, und die Hohlräume (16) mit einem daraus resultierenden Volumen bilden, dadurch gekennzeichnet, dass die beiden Bleche (11, 12) nur bei jeder zweiten der Mehrzahl der Sicken (15) miteinander verbunden sind, so dass das Volumen der Hohlräume (16) über eine Mehrzahl von Ausbauchungen vergrößerbar ist.1. Radiator ( 10 , 10 ', 10 ") for an electrical transformer with two sheets ( 11 , 12 ) provided with a plurality of beads ( 15 ) which are welded ( 17 , 17 ', 17 ") into the beads ( 15 ) are connected to one another, and form the cavities ( 16 ) with a volume resulting therefrom, characterized in that the two sheets ( 11 , 12 ) are connected to one another only at every second of the plurality of beads ( 15 ), so that the volume the cavities ( 16 ) can be enlarged via a plurality of bulges. 2. Radiator (101) nach Anspruch 1, dadurch gekennzeichnet, dass die beiden Bleche (11, 12) nur in Teilbereichen der Sicken (15) miteinander verbunden sind.2. Radiator ( 101 ) according to claim 1, characterized in that the two sheets ( 11 , 12 ) are connected to one another only in partial regions of the beads ( 15 ). 3. Radiator (10') nach Anspruch 2, dadurch gekennzeichnet, dass die Schweißungen (17') in der Mehrzahl der Sicken (15) ein Muster bilden, bei dem Ausbauchungen entstehen können. 3. Radiator ( 10 ') according to claim 2, characterized in that the welds ( 17 ') in the majority of the beads ( 15 ) form a pattern in which bulges can arise. 4. Radiator (10") nach Anspruch 1, dadurch gekennzeichnet, dass der Abstand der Schweißungen (17") in den Sicken (15) so groß ist, dass dazwischen Ausbauchungen entstehen können.4. Radiator ( 10 ") according to claim 1, characterized in that the distance between the welds ( 17 ") in the beads ( 15 ) is so large that bulges can occur between them.
