Electromechanical actuator for an internal combustion engine provided with a conditioning circuit

An electromechanical actuator to operate a component in an internal combustion engine, said electromechanical actuator comprising an actuator body housing, an actuator device supported in said housing, said actuator device being made of a first metal material and controls the movement of the component so as to move it between a maximum opening position and a maximum closing position;

• the actuator device comprises an electric motor (M) and a gear drive that transmits the motion from the electric motor (M) to the component;
• the electromechanical actuator including a conditioning circuit supported in said actuator body housing and comprising a pipe for the passage of a conditioning fluid, said pipe being made of a second thermally conductive material;
• wherein the actuator body housing includes a seat that receives the pipe and wherein a layer (S) of a structural and thermally conductive resin with a substantially uniform thickness is interposed between the seat and the pipe and is applied on the entire available surface of the seat between the pipe and the seat;
• the layer (S) of the structural and thermally conductive resin completely covers an inner surface of the seat and partially covers an outer surface of the pipe, so that the structural and thermally conductive resin does not extend out of the seat towards an upper surface of the electromechanical actuator and so as to allow the pipe to be fixed in the seat;
• and wherein both the first metal material and the second thermally conductive material are chosen from a group including:
• steel, stainless steel, aluminum or copper;
• wherein the seat has an upper side facing an upper side of the electromechanical actuator with an opening along an entire length of the seat to receive a longitudinal length of the pipe;
• and a surface that defines the seat itself, said surface having a shape that is complementary to an outer surface of the pipe.
