Heat exchanger for an electrical component, and assembly of said heat exchanger and component

An assembly comprising:

• an electrical component;
• and
• an exchanger comprising:
• a first body defining at least a primary channel and at least a secondary channel, which are parallel and adjacent, in which fluid circulates in series from the primary channel to the secondary channel, in opposite directions,
• said first body having at least one exchange surface for exchanging heat between the fluid circulating in said primary channel, said secondary channel, and said electrical component, a width of the primary channels being less than a width of the secondary channels,
• wherein the width ratio between the secondary channel and the primary channel is between 1.5 and 3.

A heat exchanger for an electrical component, said exchanger comprising:

• a first body defining at least a primary channel and at least a secondary channel, which are parallel and adjacent, in which fluid circulates in series from the primary channel to the secondary channel, in opposite directions,
• said first body having at least one exchange surface for exchanging heat between the fluid circulating in said primary channel and said secondary channel, and said electrical component, a width of the primary channels being less than a width of the secondary channels;
• wherein the exchanger comprises a manifold for circulation of the fluid to the primary channel and from the secondary channel, said manifold having an inlet and an outlet for the passage of the fluid;
• and
• wherein said manifold comprises primary stamped portions for controlling the flow of fluid between the inlet of the manifold and the primary channel.
