Abstract
A heat exchanger may include a heat exchanger block and a diffusor connected thereto. At least one connecting pin may be integrally molded to a surface of the heat exchanger block. At least one passage opening, through which the at least one connecting pin may engage when the heat exchanger is mounted, may be arranged on the diffusor. The at least one connecting pin may have a widened head via which the diffusor may be secured to the heat exchanger block.
Claims20
A heat exchanger comprising a heat exchanger block and a diffusor connected thereto, wherein:
- at least one connecting pin is integrally molded to a surface of the heat exchanger block;
- at least one passage opening, through which the at least one connecting pin engages when the heat exchanger is mounted, is arranged on the diffusor;
- and
- the at least one connecting pin has a widened head via which the diffusor is secured to the heat exchanger block.
A method for producing a heat exchanger comprising:
- producing a heat exchanger block with at least one connecting pin sticking out from a surface thereof;
- attaching a diffusor to the heat exchanger block in such a way that the at least one connecting pin engages through a corresponding passage opening on the diffusor;
- wherein the at least one connecting pin is mushroomed and the diffusor is secured to the heat exchanger block thereabove.
A heat exchanger comprising:
- a heat exchanger block;
- a diffusor;
- at least one connecting pin integrally molded to a surface of the heat exchanger block, the at least one connecting pin having a widened head securing the diffusor to the heat exchanger block, the at least one connecting pin being hollow at least on a free end thereof;
- and
- at least one passage opening arranged on the diffusor, the at least one connecting pin engaging through the at least one passage opening when the heat exchanger is mounted.
