Definitions
- the present invention relates to a method for heat dissipation in mobile radio devices and a corresponding mobile radio device.
- mobile telecommunications terminal devices or in mobile radio devices such as, for example, cell phones, PDAs and laptops
- an operating range with an ambient temperature of + 55 ° C. is generally specified.
- These mobile radio devices are constructed like a shell to the electronic components and the temperature rises from shell to shell right down to the components.
- the maximum temperature is functionally limited.
- the temperature can be 82 ° C for individual components in the ambient temperature and up to 100 ° C for the component itself.
- the electronic components convert a large part of the energy / power supplied into heat, which heats the component itself as well as its immediate surroundings. The power converted into heat is therefore a power loss.
- heat sinks or fans were mounted on the temperature-critical components.
- heat sinks make sure that there is good heat coupling between the heat sink and the electrical component, which heats up due to the power loss.
- gaps between the corresponding component and the heat sink are filled with heat-conducting foils or heat-conducting pastes.
- the distribution of heat in electrical components can be influenced by an adapted structure.
- Thermally conductive foils and pastes are better heat conductors than air, but they are also not sufficient to ensure satisfactory heat dissipation in electrical components.
- a method for heat dissipation in mobile radio devices with heat-radiating, electrical components in which the heat-radiating components are brought into heat-dissipating operative contact with a metal foil.
- the metal foil is corrugated and / or honeycomb-structured.
- a corrugated and / or honeycomb-structured metal foil By using a corrugated and / or honeycomb-structured metal foil, the resistance to heat dissipation is minimized. Due to the deformability of the corrugated and / or honeycomb structured metal foil Any gaps that occur are completely filled so that optimal heat dissipation is guaranteed.
- the honeycomb and / or corrugated metal foil can be arranged in a form-fitting manner on the surfaces to be brought into contact for heat dissipation.
- the metal foil is brought into active contact with a heat sink or a heat sink.
- a metallic body can be used as the heat sink, for example, which is either large-area for radiation and / or large-volume as a heat sink.
- the metal foil itself is used as a heat sink. Whether the metal foil itself is sufficient as a heat sink depends in particular on the amount of heat loss to be dissipated.
- the honeycomb and / or wave structure provided according to the invention offers a very large heat-radiating surface.
- the invention comprises a mobile radio device with heat-radiating electrical components, in which the components are each brought into heat-dissipating operative contact with a metal foil.
- the metal foil is preferably corrugated and / or has a honeycomb structure.
- the radiating surface is increased by using a corrugated or honeycomb-structured metal foil.
- the heat dissipation resistance is minimized on the one hand by the use of a metallic foil as well as by its corrugated or honeycomb structure.
- the metal foil is in heat-dissipating operative contact with a heat sink.
- the metal foil itself functions as a heat sink. Due to its honeycomb and / or wave structure, it has a very large heat-radiating surface.
- the present invention includes the use of a corrugated and / or honeycomb-structured metal foil for heat dissipation in the case of heat-radiating electrical components in mobile radio devices.
- FIG. 1 Schematic representation of an embodiment of the method according to the invention
- Fig. 2 shows a schematic representation of another embodiment of the method according to the invention.
- FIG. 3 Schematic representation of a further embodiment of the method according to the invention.
- a circuit board 1 which is equipped on one side with components 2 which have a large amount of heat.
- a cooling element 4 in the form of a cooling plate is arranged on the other side of the printed circuit board 1 by means of suitable connecting elements 3, which can be screws or rivets, for example.
- suitable connecting elements 3 which can be screws or rivets, for example.
- FIG. 2 shows another possibility of carrying out the method according to the invention.
- a printed circuit board 1 is shown, which is equipped on one side with a component 2 with heat loss.
- a shield cover 6 is also provided for shielding above the component 2.
- a heat sink 4 is arranged on the other side of the printed circuit board 1. It can be a heat sink, a battery or a chassis.
- a metal foil 5 is arranged according to the invention, which is corrugated and / or honeycomb-structured. The deformability of the corrugated and / or honeycomb-structured metal foil 5 enables very good contact of heat transfer.
- the metal foil 5 can only produce the transition to a heat sink 4, as here in the space between the heat sink 4 and the circuit board 1. Furthermore, the metal foil 5 itself could function as a heat sink. By using a metal foil 5 with a wave or honeycomb structure, the radiating area is increased considerably.
- FIG. 3 shows a further possibility of executing the method according to the invention.
- a circuit board 1 with lossy component 2 arranged on one side of the circuit board 1 is also shown here.
- a plastic part 7 is arranged on the other side of the circuit board 1.
- a honeycomb and / or corrugated metal foil 5 is provided between the plastic part 7 and the printed circuit board 1 and can adapt to the respective surfaces due to its good deformability. Due to its structure, the metal foil 5 itself has a very large heat-radiating surface, which is also important.
