Cooling component and method for producing same

A cooling component for cooling objects, comprising:

• at least one metal profile, which forms a heat sink, wherein the profile has multiple parallel, elongated medium channels for a flow of cooling medium therethrough, each of which is in each case delimited by a circumferential medium channel wall, which is formed by the profile;
• a first connection part made of plastic, which is connected to the profile in a fluid-tight manner, with inlet or outlet opening, via which the cooling medium is able to be fed to the cooling component or via which the cooling medium is able to be discharged from the cooling component, respectively;
• wherein in a region of the first connection part, the circumferential medium channel wall of at least one of the parallel medium channels has at least one through opening in the form of a clearance introduced into the circumferential medium channel wall, via which the medium channel is fluidically connected to the inlet or to the outlet opening of the first connection part;
• wherein the at least one through opening is a clearance introduced into the circumferential medium channel wall;
• wherein the profile is formed with a first large-surface outer side and with a second large-surface outer side spaced apart therefrom;
• and
• wherein the at least one through opening arranged in the region of the first connection part is arranged on the first or the second large-surface outer side of the profile.
