Definitions
- the invention relates to a heat dissipation device, in particular for a control device arrangement in a vehicle.
- the invention relates to a control device arrangement, in particular for a vehicle, with such a heat dissipation device.
- control unit arrangement 100 shown in FIG. 7 with a control unit 3, which comprises a housing 4 and at least one heat source 7 arranged within the housing 4, such as an electrical assembly 7A arranged on a printed circuit board 6, and with a cooling device 9A executed heat sink 9, the control unit 3 is detachably connected to the cooling device 9A.
- the at least one heat source 7 is thermally coupled to the housing 4 of the control unit 3 via a first thermal interface 8 .
- the first thermal interface 8 can, for example, consist of thermally conductive materials 8A, which are also referred to as thermal interface materials (TIM).
- TIM thermal interface materials
- a so-called gap filler which is preferably made of a thermally conductive elastomer, can be arranged as a TIM 8A between the heat source 7 and a heat dissipation dome 5.1 formed on the bottom 4 of the housing 4 and form the first thermal interface 8 .
- a heat dissipation path WAP of the heat generated by the at least one heat source 7 is distributed to a first heat dissipation path WAP1, which dissipates part of the heat generated by the heat source via the bottom 5 of the housing 4 of the control unit 3 and the fastenings tion areas to the cooling device 9A derives.
- a second heat dissipation path WAP2 dissipates part of the heat generated by the at least one heat source 7 as radiant heat and as heat conduction via air molecules via the air gap LS into the cooling device 9A.
- thermally conductive materials such as thermally conductive pastes or gap fillers
- thermally conductive pastes or gap fillers to bridge the air gap LS in order to achieve better thermal conductivity between the control unit 3 and the cooling device 9A.
- such a solution prevents a simple replacement of the control unit 3, since when the control unit 3 is dismantled, residues of the thermally conductive material used remain on the cooling device 9A, which must first be removed in a laborious cleaning process.
- appropriate heat-conducting materials must be kept available and a bubble-free application that is difficult to check and difficult to implement.
- the heat dissipation device with the features of independent patent claim 1 and the control device arrangement with the features of independent patent claim 11 each have the advantage that unevenness between egg ner heat source and a heat sink can be compensated.
- the mosaic segments adapt to the unevenness of the surface due to the compressible, thermally conductive, elastic compensation element. This means that uneven joined surfaces can also come into contact over a large area and thus have good heat transfer. Furthermore, a high degree of robustness against contamination can result, since individual dirt particles in the air gap can only prevent individual mosaic segments from being in contact. With that is a good heat transfer of all other mosaic segments is still ensured. Interstices of the mosaic segments can serve as "volume buffers".
- these spaces can, for example, serve as volume compensation for an adhesive medium that holds the mosaic segments in the corresponding receiving space. Due to the improved heat transfer, the service life of the electrical components can be extended as heat sources. In addition, cheaper materials with poorer thermal conductivity properties can be used for the housing. Furthermore, more economical manufacturing processes can be used due to extended tolerance zones.
- the thermally conductive, low-adhesion contact areas of the individual mosaic segments allow them to be easily lifted off the corresponding surface of the heat sink or heat source.
- Embodiments of the heat dissipation device according to the invention make it possible to compensate for unevenness tolerances on a cooling surface and to record good heat transfer even with unevenness of the surfaces and with particles between the surfaces, without a permanent air gap between the heat source and the cooling device.
- Embodiments of the present invention provide a heat dissipation device, in particular for a control unit arrangement in a vehicle, with a receiving space open on at least one side and at least one mosaic segment arranged in the receiving space, which has a thermally conductive and elastic compensation element and a thermally conductive low-adhesion element includes contact area.
- the at least one mosaic segment is arranged in the receiving space in such a way that the thermally conductive and elastic compensating element of the at least one mosaic segment rests against an inner surface of a floor of the receiving space and at least the thermally conductive, low-adhesion contact area of the at least one mosaic segment rests against an open side of the accommodating space, which faces the floor, partially protrudes from the accommodating space.
- an outer surface of the bottom of the receiving space forms a solid first contact surface for a heat source or for a heat sink
- the thermally conductive, low-adhesion contact area of the at least one Mosaic segment forms a flexible second contact surface for the heat sink or for the heat source.
- a control unit arrangement in particular for a vehicle, is proposed with a control unit which comprises a housing and at least one heat source arranged inside the housing, and with a heat sink designed as a cooling device.
- the control unit is detachably connected to the cooling device, with the at least one heat source being thermally coupled to the housing of the control unit via a first thermal interface.
- At least one heat dissipation device according to the invention is arranged between the control unit 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.
- the heat generated by at least one heat source is directly dissipated via the first thermal interface, via the housing of the control unit and via the at least one mosaic segment forming the second thermal interface into the cooling device.
- the at least one mosaic segment is permanently connected to the inner surface of the receiving space.
- the at least one mosaic segment can be connected to the inner surface of the receiving space, for example, by gluing, welding, soldering, clamping, or riveting.
- the at least one mosaic segment can be designed in multiple parts.
- the thermally conductive and elastic compensating element of the at least one mosaic segment can preferably be designed as a gap filler with a thickness of 1 to 5 mm, for example.
- the thermally conductive low-adhesion contact area of the at least one mosaic segment can preferably be used as a Be executed metal plate, which can be glued to the gap filler.
- the metal plates of the mosaic segments can be produced, for example, as stamped or laser-cut parts and have, for example, an edge length between 5 and 20 mm and a thickness in the range from 0.1 to 1.5 mm.
- the metal plates can, for example, be made of aluminum, copper, steel or another suitable metal. Since the gap filler is largely covered by the individual metal plates and no adhesion build-up occurs between metals, the thermally conductive low-adhesion contact area can be easily removed from a metal surface of a cooling device or a control unit housing. For example, a gap filler can be bonded over a large area to the inner surface of the receiving space for several metal plates. Then the individual metal plates of the mosaic segments can be glued with the applied gap filler. This means that several mosaic segments can have a common thermally conductive and elastic compensating element.
- the at least one mosaic segment can be made in one piece.
- the at least one mosaic segment can comprise at least one spring element, which forms the thermally conductive and elastic compensating element.
- a spring end of the at least one spring element can form the thermally conductive, low-adhesion contact area.
- the at least one spring element can be made of copper, steel or another suitable metal, for example, and welded or riveted to the inner surface of the receiving space. Since there is no build-up of adhesion between the at least one spring element and the metallic surface of the cooling device or the control unit housing, the thermally conductive, low-adhesion contact area can easily be removed from the corresponding surface again.
- At least one mosaic segment can be designed as a metal foam part, which forms the thermally conductive and elastic compensation element.
- a bearing surface of the metal foam part facing away from the bottom of the receiving space form the thermally conductive low-adhesion contact area.
- the metal foam part can, for example, be made of copper or another suitable metal and be glued, welded, soldered or clamped to the inner surface of the receiving space.
- the at least one mosaic segment can be designed as a metal wool part, which forms the thermally conductive and elastic compensation element. A bearing surface of the metal wool part that faces away from the bottom of the receiving space can form the thermally conductive, low-adhesion contact area.
- the metal wool part can, for example, be made of copper, steel or another suitable metal and be glued, welded or soldered to the inner surface of the receiving space. Since there is no build-up of adhesion between the metal foam part or the metal wool part and the metal surface of the cooling device or the control unit housing, the corresponding thermally conductive low-adhesion contact area can be easily removed from the corresponding surface again.
- the at least one mosaic segment can be designed as a metal lamellar structure, which is also referred to as “Skived Fins” and comprises a number of lamellas that protrude from a base plate and form the thermally conductive and elastic compensation element.
- the base plate can rest against the inner surface of the bottom of the receiving space and the edges of the lamellae facing away from the base plate can form the thermally conductive, low-adhesion contact area.
- the at least one mosaic segment can be designed as a metal knob foil, which can comprise a plurality of knobs protruding from a base area, which form the thermally conductive and elastic compensating element.
- the base of the metal studded foil can rest against the inner surface of the floor of the receiving space and be glued or welded to it. The knobs facing away from the base plate can form the thermally conductive, low-adhesion contact area.
