The invention relates to a heat exchanger that is configured to permit an exchange of heat between a first fluid and a second fluid that circulate in passage paths formed by plates () and fins () of the heat exchanger, the fluids flowing in a multitude of passage channels () each consisting of a closed space () delimited by two adjacent plates and two adjacent fins,

The invention relates to a regulator, configured to receive a hot air flow via an air inlet (), to treat this hot air and to transmit the treated hot air to an air outlet () configured to supply a pneumatic actuator (), comprising at least one temperature-sensitive electrical and/or mechanical element (), and a regulator body (). The regulator is characterized in that the regulator body is composed of a heat-conducting hollow enclosure () at least partially surrounding a duct () for transporting the hot air flow, said cavity being at least partially filled with a metal mesh produced by additive manufacturing that allows the cooling air to circulate, and in that the temperature-sensitive electrical and/or mechanical element () is arranged in, or in contact with, the regulator so as to be cooled by the cooling air by thermal conduction.
