- Base body the same size as a thickness of the first heat conducting element.
- first heat-conducting element is within the
- Isolation element are advantageously mounted on the first heat conducting element. It is particularly preferred that the second
- Heat conducting element and the insulation element are arranged on the first heat conducting element and the base body.
- the second heat-conducting element and the insulating element rest on a surface that is jointly formed by the main body and the first heat-conducting element.
- the insert is pressed into the body.
- the insert is inserted into a recess of the base body.
- the recess is in particular a cutout or a bore, wherein the recess extends particularly advantageously through the entire thickness of the base body.
- the second heat-conducting element is arranged within the base body, with one dimension, particularly preferred a length and / or width of the second heat-conducting element is smaller than the same dimension of the first heat-conducting element.
- the dimension of the second heat-conducting element is also smaller than the corresponding dimension of the insulating element.
- the first heat-conducting element preferably has a greater thickness than the second heat-conducting element. This leads to improved heat spreading and heat buffering, which ensures better thermal performance, ie greater heat dissipation.
- the first heat-conducting element and / or the second heat-conducting element are made of copper or aluminum. Both materials have optimal thermal conductivity and therefore are particularly advantageous for heat dissipation of components.
