Distribution assembly and associated electrical panel

A distribution assembly, configured to distribute electrical energy from a power source to at least one electrical load, the power source comprising a neutral and at least one phase, wherein:

• the distribution assembly comprises a power bus, which comprises a plurality of busbars:
• which include at least one phase bar, each phase bar being associated respectively with a phase of the power source,
• which extend parallel to each other along a main axis of the distribution assembly and are aligned along a height axis that is orthogonal to the main axis,
• the busbars each each comprise:
• a power supply portion, which is configured to be connected to an output terminal of a main housing in a mounted configuration of the main housing,
• a connection portion, which extends from a single side of the power supply portion, the connection portions being geometrically situated on a front side of a connection plane parallel to the main axis and to the height axis and together defining a connection zone of the power bus, the connection zone being configured to receive at least one outgoing box so that outgoing box is connected to the power bus, each outgoing box being capable of being connected to a respective electrical load, so as to supply electrical power to the electrical load,
• the distribution assembly comprises a cooling device, which includes:
• a contact plate, which has a contact face that extends parallel to the connection plane, the contact face being configured to cooperate, in particular through complementary shapes, with a rear face of the main housing in a mounted configuration, so as to promote thermal transfer between the contact plate and the main housing,
• a radiator that extends along the connection zone, on a rear side of the connection plane,
• at least one heat pipe, which connects the contact plate to the radiator and is configured to transfer some of the heat collected by the contact plate to the radiator, the radiator being configured to dissipate the heat transferred by each heat pipe into the air.
