Definitions
- generating components are arranged
- the invention relates to an electronic device with a housing, wherein in the housing a heat generating first component, a heat generating second component and a cooling system are arranged. During operation of the device, the first and second components are replaced by the
- Electronic devices in particular computer systems, usually comprise several heat-generating components or
- RAM Random Access Memory
- system boards or other such components.
- RAM Random Access Memory
- Each component generates a power loss, which manifests itself in the form of waste heat on the component.
- Cooling system usually a fan system for generating a cooling air flow or water cooling
- this waste heat can be dissipated by the components and discharged to the outside to the environment.
- a heat sink with cooling ribs or cooling vanes is arranged on or on the components, which significantly improves the heat output.
- the heat-generating components in such systems have different operating temperatures depending on their respective capacity utilization and connection to the cooling system.
- air ducts complex airflow control measures via air ducts (so-called "air ducts") are usually combined with a deployment
- This task is performed by an electronic device
- generating component is connected via a heat-conducting connection with the second heat-generating component, such that a lower temperature of the first component and a higher temperature of the second component are matched to one another.
- Components can be replaced so that waste heat of the hotter component is transported through the heat conductive connection to the cooler component. Although this has the consequence that the cooler component heats up a bit, it has the advantage that the hotter one
- Component cools down a bit.
- the temperature of the hotter component can be lowered, so that the
- Cooling capacity of the cooling system can be reduced.
- Cooling system can be designed more moderate.
- Cooling medium The components are cooled more efficiently, the
- Excess of cooling capacity based on the first cooler component can be kept lower than at
- the temperature of the first component and the temperature of the second component are balanced to an approximately equal temperature level.
- the heat-conductive connection compensates for temperature differences in the operating temperatures of the components.
- the first component is arranged in the direction of a cooling air flow of the cooling system in front of the second component such that at least part of the exhaust air flow of the first component impinges on the second component.
- the components are arranged to save space with a small component volume in a housing.
- Component is due to the heated by the waste heat of the first component air is additionally heated. Furthermore, the second component lies in the shadow of the first
- Cooling system reaches the second component. All this leads to a temperature imbalance between the two
- the heat conductive compound comprises
- Heat pipe This is used in particular for the heat conduction between a heat source (here the hotter component) and a heat sink (here the cooler component). Due to heat conduction in the heat pipe, the operating temperatures of the two components can be matched to each other.
- Figure 1 shows a first embodiment of an electronic
- Figure 2 shows a second embodiment of an apparatus
- Figure 3 is a perspective view of another
- Embodiment of an electronic device Embodiment of an electronic device.
- Figure 1 shows a first embodiment of a
- both components 3 and 4 may represent two processors of a computer system or the like.
- a cooling system 5 here by way of example in the form of a fan, is furthermore arranged in the housing 2.
- the cooling system 5 generates a cooling air flow 7, which first on the first
- Component 3 and then meets the second component 4. In the direction of the cooling air flow 7 behind the second component 4 can on an outer wall of the housing. 2
- a ventilation opening (not shown) may be provided to dissipate the waste heat generated from the outside of the housing 2.
- Component 4 partly in the shadow of the first component. 3 with respect to the cooling air flow 7, so that only a part of the cooling air flow 7 and thus only a part of a
- the second component 4 can heat up more strongly than the first component 3.
- the components 3 and 4 are conductive via a heat
- the heat-conducting connection 6 includes, for example, a heat pipe.
- the heat pipe or heat pipe (“heat pipe”), for example, have an outer shell and an inner capillary, in which a
- Working medium such as water
- the Capillary braid for example, by a
- Copper wire mesh be designed with high thermal conductivity.
- the advantage of such a heat pipe is that the heat can be transported very well, since a stream of working fluid through the wick structure of the
- Heat pipe Such heat pipes are widely used in computer systems.
- the heat-conducting connection may for example also be formed by a metal or copper bar between the two components 3 and 4, wherein due to a
- Heat transfer in the heat conductive connection 6 heat can be dissipated on the heat sink, so that the total
- Heat removal from the hotter component 4 can be improved.
- the cooling capacity of the cooling system 5 can be reduced because the maximum operating temperature to be cooled, here the hotter component 4, is lowered. Furthermore, a more balanced temperature ratio is created in the housing 2, wherein regional zones of different heat sources and sinks can be at least partially compensated.
- a reduction in the cooling capacity of the cooling system for example, according to the embodiment in Figure 1 means a reduction of the fan speed and thus a reduction of the noise in the electronic device.
- Figure 2 shows a second embodiment of a
- Housing 2 also two components 3 and 4 with
- a cooling system 5 in the form of a fan cools the two components
- Cooling air flow 7 to the second component 4 passes. So here is a high imbalance between the
- the two components 3 and 4 are arranged on a heat-conducting compound 6, which is here plate-shaped.
- the heat-conducting connection 6 can work according to one of the principles explained above.
- the operating temperatures of the components 3 and 4 may be equal to each other and will preferably balance to a nearly uniform temperature level.
- the maximum operating temperature namely the temperature of the hotter component 4, lowered, so that the performance of the cooling system 5 can also be lowered. This has, as already explained, the advantage that the cooler component is not disproportionately and the hotter component 4 still sufficiently cooled.
- FIG. 3 shows a perspective view of a
- a part of a housing 2 is shown schematically.
- the components 3 and 4 and the heat-conducting connection 6 have heat sink, the cooling fins or cooling vanes in a cooling air flow of a cooling system (not shown) are located.
- waste heat can be removed from the components 3 and 4 as well as from the heat-conducting connection 6. Due to the heat conductive connection 6 between the two components 3 and 4, almost a balance of
- RAM memory slots
- processors of a computer system For example, processors of a computer system.
- the two components 3 and 4 are in this case
- Component can be lowered. This has the advantage that a cooling system in such a device only has to be designed for the average operating temperature. Due to the heat conducting connections between all components, a balanced level of heat is established in the device, with locally distributed heat sources or heat sinks
- the heat conductive connection can be made in many ways. It is possible, only a metal ⁇ or copper bar or a corresponding plate-shaped
- Thermosiphon provide. Such designs may be flowed through by different working media, for example water or coolant.
- the thermal conductivity of the heat-conducting connection 6 is at the corresponding
