Document Type and Number:
WIPO Patent Application WO/2021/045370
Kind Code:
A1
Abstract:
The present invention relates to a coolant/air heat exchanger for a motor vehicle, exhibiting multiple fluid-carrying metal pipes, whose pipe ends are arranged next to one another with spacing, at least one pipe base produced from plastic (1; 1') with mounting holes (12), into which the pipe ends can be mounted and one header (2; 2') produced from plastic with a snap-in locking device, which is formed between the pipe base (1; 1') and can be connected to the pipe base, wherein the snap-in locking device is formed with pipe base clip elements (3; 3a; 3b; 3a'; 3b') arranged on the pipe base (1; 1') and header clip elements (4; 4') arranged on the header (2; 2'), with which a snap-in connection can be created through a mechanical interaction of the individual pipe base clip elements (3; 3a; 3b; 3a'; 3b') and corresponding individual header clip elements (4; 4'), and wherein a seal (11; 11') is produced that guarantees a press fit of the pipe base (2; 2') on the pipe ends and seals off the header (2; 2') against the pipe base (1; 1'), as well as the pipe base (1; 1') against the pipe ends.
