Definitions
- An object to be solved is to provide a motor vehicle headlamp with improved thermal management.
- the motor vehicle headlamp has a lighting device which comprises at least one light-emitting diode chip.
- the illumination device comprises a multiplicity of light-emitting diode chips.
- the illumination device forms a light source of the headlight.
- the headlight comprises a heat pipe or a thermosiphon.
- the heat pipe or the thermosiphon has an evaporation area. At the evaporation area, the heat pipe or the thermosiphon absorbs heat. Furthermore, the heat pipe or the thermosiphon has a condensation region. At the condensation area, the heat pipe or the thermosiphon releases part of the heat absorbed at the evaporation area to the environment.
- the evaporation area is thermally connected to the
- Lighting device coupled. ' That is, the heat pipe or the thermosiphon receives at least a portion of the heat generated by the lighting device during operation at the evaporation area. The absorbed waste heat is led from the heat pipe or the thermosiphon to the condensation area of the heat pipe or the thermosyphon.
- the condensation region of the heat pipe or the thermosiphon is connected to a heat sink.
- the heat sink is preferably mechanically fixed to the heat pipe or the thermosiphon. For example, it is soldered or jammed with the heat pipe or thermosyphone. But it is also possible that the heat sink is formed integrally with the heat pipe or the thermosiphon. That is, the heat sink may, for example, be an integral part of a pipe of the heat pipe or the thermosyphone. Heatsink and tube are then connected together without an interface and can be made together, for example, in a single operation. The heat sink releases at least part of the heat absorbed by the lighting device to the environment.
- the motor vehicle headlight has a lighting device which comprises at least one light-emitting diode chip. Furthermore, the motor vehicle headlight on a heat pipe or a thermosiphon.
- the heat pipe or the thermosiphon comprise an evaporation area and a condensation area.
- the evaporation region is thermally connected to the illumination device.
- the Condensation area is connected to a heat sink.
- the heat sink releases heat absorbed by the illumination device to the environment.
- the vehicle headlight described here makes u.a. to make use of the knowledge that a motor vehicle headlight has areas of very different temperatures. That is, in the motor vehicle headlight, a large temperature gradient can occur. In the case of a large temperature gradient, the use of heat pipes or thermosiphons for heat transport proves to be particularly efficient. For example, due to the waste heat of the engine and the illumination device in the area of the illumination device, temperatures of up to 150 ° Celsius can occur. On the cover of the headlamp, through which the light generated by the illumination device leaves the headlamp, the temperature is in the range of the outside temperature. A heat transfer from the illumination device to the cover can therefore be particularly efficient.
- the heat sink comprises at least one cooling structure.
- the cooling structure of the heat sink can be given for example by a comb-like surface of the heat sink.
- the heat sink it is possible for the heat sink to comprise cooling ribs or cooling slats.
- the cooling structure is suitable to increase the surface of the heat sink. This allows a particularly efficient dissipation of heat to the environment of the heat sink.
- the heat sink contains or consists of a good heat-conducting material such as a metal.
- the heat sink can contain, for example, copper and / or aluminum or consist of one of these metals.
- the evaporation region of the heat pipe or the thermosiphon is thermally connected to the underside of the illumination device facing away from the main emission direction of the light-emitting diode chip.
- the illumination device may, for example, comprise a connection carrier on which the light-emitting diode chip is applied. The main emission direction of the LED chip is then directed away from the connection carrier.
- the evaporation region of the heat pipe or the thermosiphon can be connected directly to the underside of the illumination device.
- the vehicle headlight described here makes u.a. to use the knowledge that light-emitting diode chips have an operating temperature of at most 150 ° Celsius and therefore only one - compared to the example for heat transfer by heat conduction - small proportion of the heat loss is given by heat radiation to the environment. A large part of the heat is released by means of heat conduction to the connection carrier for the LED chips. Therefore, it proves to be particularly efficient to absorb the heat on the connection carrier and remove it from there.
- the evaporation region of the heat pipe or the thermosiphon is connected to a heat conduction body.
- the heat-conducting body may be, for example, a plate which consists of a particularly good heat-conducting material such as copper and / or aluminum or contains one of these materials.
- the heat-conducting body of a thermally conductive composite material such as AlSiC, CuSiC or Al Diamond formed.
- the heat-conducting body is preferably thermally connected to the lighting device and / or coupled.
- the heat conducting body for example mechanically - for example by means of a solder connection - be connected to the underside of the lighting device.
- the evaporation region may be in the form of a main body.
- the main body then forms the heat-conducting body to which a pipe circuit - in the case of a loop thermosiphon - or a simple pipe - in the case of a thermosiphon - is connected. Heat-conducting body and thermosiphon are thus integrally formed.
- the illumination device can be connected, for example, by means of soldering or terminals with thermal paste thermally conductive to the perennialleitk ⁇ rper.
- the heat sink emits at least part of the heat absorbed by the illuminator to a cover of the motor vehicle headlamp.
- the cover of the vehicle headlamp is formed from a material which is transparent at least for a large part of the electromagnetic radiation generated by the LED chip.
- the cover consists of a glass. The electromagnetic radiation generated by the lighting device during operation leaves the vehicle headlight through the cover.
- the heat sink may be in direct contact with the cover, for example. But it is also possible that the heat sink is arranged in the immediate vicinity of the cover of the headlight, so that there is a gap between the heat sink and cover, which is preferably filled with air.
- the heat is removed from the heat sink by heat conduction and / or convection.
- the heat sink is arranged on the vehicle underside facing the underside of the cover. In this way, the rising by free convection heat - ie, for example warmed air - be distributed over the entire cover.
- the heat sink is arranged at the top of the cover. Compared to an arrangement at the bottom while this results in less favorable conditions for the free convection of heat, however, improves the heat transfer of the heat pipe or the thermosiphon, since the gravity supports the return of the condensate in the cooling circuit.
- the heat sink extends over at least 50% of the length of the cover disk. Preferably, the heat sink extends over at least 75% of the length of the cover of the vehicle headlamp.
- the heat emitted by the heat sink can be distributed particularly uniformly over the entire cover of the headlight. This allows, for example, a particularly fast, large-scale deicing an icy cover. At least some of the heat emitted by the lighting device during operation can be used in this way in a particularly efficient way for heating and / or defrosting the cover pane.
