An absorber for a thermal collector of a solar installation, comprising:
- two metal sheets arranged one on top of the other forming an absorber wing for light and heat conversion, the two metal sheets defining a pipe system therebetween for conducting a heat transfer medium, wherein a shape of the pipe system is introduced into at least one of the two metal sheets;
- an adhesive bonding the two metal plates to one another;
- and
- a formfitting connection between the two metal plates, the formfitting connection being a clinched connection.
A method for manufacturing an absorber for a thermal collector of a solar installation, the absorber including two metal sheets arranged one on top of the other forming an absorber wing for light and heat conversion, the two metal sheets defining a pipe system therebetween for conducting a heat transfer medium, said method comprising the steps of:
- cold forming at least one of two metal sheets of the absorber for introducing a shape of the pipe system;
- joining the two metal sheets using an adhesive;
- and
- generating a formfitting connection between the two metal sheets using clinching.
