Housing for an electrical apparatus

A housing for an electrical apparatus, the housing comprising:

• a first chamber designed to house first electrical components,
• a second chamber designed to house second electrical components,
• an interface separating the first chamber and the second chamber,
• a cooling circuit configured to circulate a fluid used to cool the electrical apparatus, the cooling circuit being formed in the interface,
• wherein:
• the interface comprises a non-through hole that extends from the first chamber to the second chamber and is configured to form a cavity used to house a first electrical component;
• the interface comprises a first surface on the side of the first chamber and a second surface opposite the first surface on the side of the second chamber, and the non-through hole extending from a first opening in the first surface, wherein the first opening is sized to receive the first electrical component, the first electrical component being inserted into the cavity through the first opening so that a height of the portion of the first component that protrudes from the cavity is smaller than a height of the first component;
• and
• the non-through hole is also formed by a protrusion that extends from the second surface toward the second chamber;
• wherein the cavity is not open in/to the second chamber and the first component is a capacitive block that contains several capacitors having parts that are at a same level as the interface, the capacitors being interconnected by a flat electrical connector.
