Power supply module for heating radiator and heating radiator fitted with such a module

A power supply module for a heating radiator, the power supply module comprising:

• a single printed circuit board;
• a plurality of electronic switches;
• and
• a plurality of connectors to an external circuit;
• wherein the single printed circuit board comprises a first zone providing a first electrical connection with a heating body of the heating radiator, a second zone providing second electrical connection with the plurality of electronic switches, and a third zone providing third electrical connection with the plurality of connectors;
• wherein the heating body is configured to heat an air flow by passing the air flow in a first direction through the heating body;
• wherein the first, second, and third zones are located on one face of the single printed circuit board, side by side in that order in a second direction transverse to a plane of extension of the heating body;
• wherein the plurality of electronic switches is placed in an immediate vicinity of the heating body such that heat given off by the plurality of electronic switches directly dissipates in the first direction of the air flow through the heating body to further heat the air flow;
• wherein the third zone extends in a median zone so as to give the single printed circuit board a T-shaped configuration, the third zone forming a longitudinal branch of the T-shaped configuration and the first and second zones forming a transverse branch of the T-shaped configuration;
• wherein the plurality of connectors extend from lateral edges of the longitudinal branch of the T-shaped configuration in a direction parallel to a transverse border of the T-shaped configuration.
