Heat dissipating device and controller assembly

A controller assembly for a vehicle, comprising:

• a controller which includes a housing, and at least one heat source arranged inside the housing;
• and
• a heat sink configured as a cooling device, the controller being detachably connected to the cooling device, the at least one heat source being thermally coupled to the housing of the controller via a first thermal interface, at least one heat dissipating device being arranged between the controller and the cooling device which forms a second thermal interface between the housing and the cooling device, and dissipates heat generated by the at least one heat source to the cooling device;
• wherein the at least one heat dissipating device including:
• a receiving area open on at least one side, and
• at least one mosaic segment which is arranged in the receiving area and includes a thermally conductive and elastic compensation element and a thermally conductive low-adherent contact region, wherein the at least one mosaic segment is arranged in the receiving area such that the thermally conductive and elastic compensation element of the at least one mosaic segment rests against an inner surface of a base of the receiving area and at least the thermally conductive low-adherent contact region of the at least one mosaic segment partly protrudes out of the receiving area at an open face of the receiving area which is opposite the base, wherein an outer surface of the base of the receiving area forms a rigid first contact surface for the heat source, and the thermally conductive low-adherent contact region of the at least one mosaic segment forms a flexible second contact surface for the heat source,
• wherein a direct heat dissipation of heat generated by the at least one heat source via the first thermal interface, via the housing of the controller, and via the at least one mosaic segment forming the second thermal interface into the cooling device takes place.
