Cooling device and method for producing same

The device has cooling bodies (102) arranged adjacent to each other and comprising a cooling channel (106) i.e. tube, and a form-fit structure, which is provided at oppositely lying boundary areas or side surfaces. The cooling bodies are connected with each other via the form fit structure. A connection element is arranged between two adjacent cooling bodies to connect the cooling bodies via a form-fit connection, force-fit connection and an adhesive bond- or soldering connection. The bodies are designed as plates, strand press profiles or extrusion profiles made of metal or plastic. The form fit structure is designed as a groove and a spring, and the connection element is designed as a spacer, a screw and a clip. An independent claim is also included for a method for manufacturing a cooling device for cooling electrical components.
