Housing for an electric or electronic device
A housing includes a cup-shaped, plastic housing case; a cooling channel guided in the housing case for fluid cooling of an electric or electronic device situated in an interior of the housing case; and a planar shielding body integrated into the housing case and traversing walls of the housing case for shielding from electromagnetic radiation. The shielding body is a metallic wire cage or trough. The cooling channel is a metallic tubing. The shielding body and the cooling channel are connected to form a frame-like, pre-assembled assembly. The pre-assembled assembly, consisting of the shielding body and the cooling channel, is extrusion-coated with a plastic or encapsulated in a plastic to form the housing case.
1. A housing for an electric or electronic device, comprising:
a cup-shaped, plastic housing case;
a cooling channel guided in the housing case for fluid cooling of an electric or electronic device situated in an interior of the housing case;
a planar shielding body integrated into the housing case and traversing walls of the housing case for shielding from electromagnetic radiation; and
wherein the shielding body is a metallic wire cage or trough, the cooling channel is a metallic tubing, the shielding body and the cooling channel are connected to form a frame-like, pre-assembled assembly, and the pre-assembled assembly, consisting of the shielding body and the cooling channel, is extrusion-coated with a plastic or encapsulated in a plastic to form the housing case.
2. The housing of claim 1 further comprising:
metallic cooling elements connected to the shielding body and/or the cooling channel to further form the pre-assembled assembly, the cooling elements extending at least to surfaces of the interior of the housing case.
3. The housing of claim 2 wherein:
the cooling elements form fastening elements for components of the electric or electronic device situated in the interior of the housing case.
4. The housing of claim 1 further comprising:
a housing cover having a metallic shielding surface therein; and
the housing cover is connectable to the housing case to close off the interior of the housing case.
5. The housing of claim 4 wherein:
the shielding body integrated in the housing case and the shielding surface in the housing cover are electrically connected to one another when the housing cover is connected to the housing case.
6. The housing of claim 1 wherein:
the cooling channel has a feed line and a discharge line that are led out from the housing case.
7. The housing of claim 1 wherein:
the cooling channel has a shape having multiple bends within the housing case.
8. The housing of claim 1 wherein:
for manufacturing the housing case, the pre-assembled assembly is wound with a low-viscosity compound which cures with release of heat.
9. The housing of claim 8 wherein:
after curing, the low-viscosity compound forms a body made of a thermosetting material.
10. The housing of claim 9 wherein:
the thermosetting material is a polyurethane or a polyurea.
11. The housing of claim 8 wherein:
the low-viscosity compound includes thermal conductive fillers.
