FIELD: electrical engineering electronic engineering), in particular, constructions of on-board and ground electronic equipment.
SUBSTANCE: the device has a housing and functional cells representing heat abstracting bases with printed circuit boards with electronic elements sticked to them, each heat abstracting base is made with lower and side heat discharge channel the heat abstracting base of each cell is additionally provided with an upper heat discharge channel, and the housing walls are formed by the end face surfaces of the similar heat discharge channels of the adjacent cells tightly pressed to each other.
EFFECT: improved mass-dimensional characteristics, which is of a special interest for on-board equipment; reduced thermal resistance and temperature gradient between the electronic elements and the environment; enhanced reliability.
