- Components is expected from a certain temperature.
- Cooling systems according to the subject invention are used for electronic devices in the broadest sense, to ensure their performance, their life and their efficient operation.
- cooling systems can also be used in electronic household appliances, in electronic measuring devices as well as in devices of consumer electronics and similar devices.
- cooling elements based on aluminum and copper are used, which are in contact with the loss-heat-generating electronic component and absorb the heat first and deliver it via heat conduction and a lamellar enlarged surface to the environment.
- a cooling system for a CPU based on the thermo-siphon principle is disclosed.
- the evaporator is positioned on the CPU and coupled with a heat exchanger via a steam line.
- the condensate flows from the heat exchanger in a separate, from the
- a heat transfer unit is disclosed in the prior art for the CPU cooling of a laptop computer according to EP 0 767 415 A2, wherein in turn an evaporator is positioned on the CPU and the refrigerant vapor is first conveyed to a condenser via a steam line and from there the condensate is returned to the evaporator via a second condensate return line.
- a heat transfer element with refrigerant for use in a computer is disclosed.
- the evaporator is connected via a steam line to the condenser and the return of the condensate via a separate condensate line.
- the cited prior art systems suffer from the disadvantage that two lines are required to first deliver the vapor via a vapor line from the evaporator connected to the heat source to the condenser, and then the condensate via a condensate line from the condenser back to the evaporator to transport.
- Another concept of device cooling is based on the use of heat pipes, which is characterized in that one or more Heatpipes are placed with the evaporator side on the electronic component and the heat loss by evaporation on the electronic component and condensation in the evaporator facing away from the part of the heat pipe, which acts as a capacitor, is discharged to the environment.
- a cooling unit for an electronic component which is designed as a heat pipe and is U-shaped.
- the two ends of the heat pipe act as an evaporator and are connected to the loss-heat generating electronic component.
- Between the parallel legs ribs are arranged up to the arc region, which form the condenser part of the heat pipe.
- Several U-shaped bent heatpipes are connected to each other via fins, which leads to the formation of a condenser block in the upper area, and in the lower area a plurality of evaporator areas of the heat pipe are positioned on the electronic component.
- a cooling device which also requires only a pipe for steam and condensate transport.
- the forming in the evaporator refrigerant vapor rises and condenses on the outer wall in the upper part of the heat pipe and flows back to the wall in the evaporator.

- a cooling system for computers which cool several heat loss sources in an electronic device can. It is connected via a heat pipe, a waste heat generator with a condenser in the form of a louver, through which the cooling air flow is passed.
- the refrigerant vapor condenses in the condenser designed as a louver, and the condensate is conveyed via the heat pipe back to the evaporator.
- heat is transferred to the condenser of the heat pipe via the heat conduction of a metal plate from another heat loss source.
- the air guiding device also absorbs this heat transported by heat conduction and delivers it to the cooling air flow flowing through the air guiding device.
- a disadvantage of the prior art on cooling systems with a pipe for transporting steam and condensate is that only a small condenser surface is available and thus the transferable amounts of waste heat are limited. Due to the air cooling and the associated poor heat transfer coefficients, the condenser surface available in this way on the air side is too low.
- the object of the present invention is to transport larger amounts of waste heat with a cooling system which can be produced cost-effectively and thus to ensure a better cooling effect.
- a cooling system for electronic devices comprising an evaporator, a Dampfverteil- and condensate collecting element and a condenser with a plurality of condenser tubes and connecting the condenser tubes fins block, wherein the condenser tubes are arranged parallel to each other and from the Dampfver notoriouss- and Condensate collecting element extend upwards and are closed at its upper end.

- Condensate collecting element along a surface line of the horizontal tube involved.
- a connecting line provided between the evaporator and the steam distribution and condensate collecting element.
- the connecting line is designed as a pipe with a heatpipe structure.

- the capacitor area is significantly compared to the known heat pipes by the inventive arrangement of Steam distribution and Kondensatsammeielementses enlarged. This ensures that the small evaporator surface is optimally utilized and is brought into a favorable ratio of evaporating power and capacitor performance.
- the embodiments according to the invention with connecting lines are advantageously suitable to conduct heat from the heat source to suitable locations for capacitors in the form of vapor transport in order to be effective there with higher efficiency with a correspondingly large-sized capacitor.

- a cooling system which consists essentially of the components evaporator 1, connecting line 4 to the steam distribution and condensate collecting element 3 and condenser 2 with finned block 5 and condenser tubes 6.
- the connecting line 4 is designed as a simple tube without an inner heatpipe structure 8.
- This embodiment of the invention is advantageously used in applications in which the heat source is below the heat sink and both are not arranged in close proximity to each other.
- the vapor formed in the evaporator part passes via the connecting line 4 in the tubular Dampfver notoriouss- and condensate collection element 3.1 and from there into the condenser 2.
- the condensate forming in the condenser 2 collects in the tubular Dampfver Krebss- and Kondensatsammeleiement 3.1 and is placed over the laid without water sacs connecting line 4 returned to the evaporator 1, where the cycle of the refrigerant closes and the evaporation begins again.
- the integration of the connecting line 4 takes place as shown in the axial direction over an end face of the tubular Dampfver Krebss- and Kondensatsammelelement.es 3.1, being ensured that the reflux of the condensate to the evaporator 1 at the lowest point of the steam distribution and condensate collection element 3.1 can be done.

- the respective condenser tube 6 is made permeable to steam, so that steam can pass through the steam distribution and condensate collecting element 3.1 into the other condenser tubes 6 and a reflux of the condensate in an analogous manner is possible.
- a particularly advantageous dimensioning is shown, which consists of four condenser tubes 6 with lamella block 5 and can also be used for the passive cooling of computer processors. This means that if the power supply configuration is adapted to the cooling system, it can also be operated without the use of a separate fan.
- FIG. 3 shows a cooling system according to the invention, which is equipped with a condenser 2 and a tubular vapor distribution and condensate collecting element 3 analogously to the embodiments in FIG. 1 and FIG.

- the connecting line 4 which is designed as a tube without heatpipe structure 8, to the lying below the condenser 2 evaporator 1 in height H above the lowest point of Dampfver notorioussund condensate collection element 3.1 lie. This is necessary in order to allow condensate accumulation and condensate transport by means of connecting line with heatpipe structure 7 to evaporator 1 arranged above vapor distribution and condensate collecting element 3. Condensate transport then takes place smoothly if the insertion length L and the overlap associated with it are dimensioned sufficiently large to utilize the capillary action of the heatpipe structure.
- the height difference H and the insertion length L are thus required for sufficient flooding of the capillary structure with condensate in order to ensure safe operation of the evaporator 1 arranged above the steam distribution and condensate collecting element 3.
- the dimensions H and L are dependent on the filling amount, the diameter D and the transport capacity of the heatpipe structure of the connecting line 7 and the thermal load of the system.
- the height H of the supernatant is about 0.5 to 1 times the diameter D of the tube with the heatpipe structure 7.

- the connecting line 7 is provided with an inner heatpipe structure, whereas the connecting line 8 is arranged for below the Dampfver Krebss- and condensate collecting element 3 evaporator 1 as a smooth tube, since in the latter case, the condensate driven by gravity flows back to the evaporator 1.
- 4 shows an alternative embodiment of the cooling system, wherein the tubular Dampfver Krebss- and Kondensatsammeielement 3.1 modular from sleeves 9 for incorporation of the condenser tubes 6 and spacers 10 is.
- the design of the tubular Dampfverottis- and Kondensatsammeiiatas 3.1 from sleeves 9 and connectors 10 advantageously allows the flexible adaptation of the capacitor surface and power to different applications of the cooling system.
- the connecting line 4 or the tube with heatpipe structure 7 and the tube without heatpipe structure 8 may have a length of up to 90 cm.
- materials for good or bad heat conductive materials are advantageously used depending on the application.

- Heat conductive connector the line can also be thermally insulated accordingly, so that the heat flow is reduced to the interior of the device.
- Figure 5 discloses in cross section an alternative structural realization of a cooling system according to the invention, wherein the steam distribution and condensate collection element 3.2 is formed flat and orthogonal to this
- the condenser tubes 6 are arranged.
- the Evaporator 1 and the areal steam distribution and Kondensatsammeielement 3.2 thereby formed as a unit, so that no connecting lines between the evaporator 1 and the steam distribution and condensate collecting element 3.2 are required.
- this implementation of the invention can only be used in electronic devices whose space permits such an arrangement.
- the capacitor 2 has a larger area requirement directly above the heat loss generating electronic component. Due to the possibility of incorporating a larger number of condenser tubes 6 into the planar vapor distribution and condensate collecting element 3.2, it is possible, with a significantly smaller tube length than shown in FIG. The alternative structural realization thus enables the design of very compact designs of the cooling system according to the invention.

- the upper planar segment consists of an upper extension element 13 and an intermediate piece 10, at the junction of the tie rod 11 is integrated at its upper end.
- the tie rod 11 stabilizes the surface Dampfverteiiungs- and Condensate collecting 3.3 and thus allows the use of refrigerants with high operating pressures.
- the advantages of the invention are that an arbitrarily large capacitor can be used by the steam distribution.
- Experience has shown that the heat absorption in the evaporator must be very concentrated, since the loss of heat production is concentrated in electronic components on a very small area.
