A housing arrangement including a receiving housing with an interior inside which a cooling device and one or several electric units are accommodated. The cooling device includes a flow line and a return line extending at least partially between the base area and ceiling area of the receiving housing. Connecting lines run from the flow line and the return line and are physically connected to a cooling circuit of one or several electric units. Effective cooling of receiving areas which are fitted in a complex manner with built-in components is obtained because a distributor line is respectively guided from a flow line and a return line to a distributor which is maintained inside the receiving housing. The distributor includes several distributor connections that can be connected to connection lines which are guided to the electric built-in component, such as a computer unit.
