Last but not least, the present invention relates to the use of the contamination-free coolable, enclosed, heat-dissipating during operation, electrical and electronic components and devices in clean rooms, clean rooms, operating theaters, intensive care units, isolation stations and microbiological, biological, analytical, medical, pharmacological, nanotechnological or electrical engineering, Research facilities and production facilities as well as in research facilities and production facilities for wafers, data carriers, microchips, smartphones and computers as well as in aviation and aerospace technical research facilities and production facilities.

State of the art

The prior art cited in the present application is incorporated by reference into the present application.

Enclosed enclosures, electrical and electronic components and devices can generate significant amounts of heat during operation. This must be dissipated so that the heat does not damage the components and the devices themselves, their environment and / or the operating personnel and / or other persons such as patients and / or other living beings. Usually, the cooling is done by ventilation, in which an air flow is blown or sucked through the housing on or by the heat-emitting electrical or electronic components and devices. However, this requires air intakes and air outlets in the housings. However, such a method involves a high risk of contamination, in particular by microorganisms such as bacteria, fungi, viruses, protozoa, microalgae and archaea, spores, pollen, particulate matter, particulate matter, suspended solids, aerosols, chemical contaminants and / or nanoparticles, the electric and electronic components and devices. In the worst case, even small animals and micro animals can penetrate.

Thermoelectric elements (TEE) or Thermoelectric Coolers (TEC), also known as Peltier elements, are electrothermal transducers that produce a temperature difference when current flows, or a current flow at temperature difference. Basically, a TEC includes two legs made of different thermoelectric materials having different Seebeck coefficients, which are electrically conductively connected to each other at a pad or in a contact region. An elevated temperature in the contact area compared to the temperature of the other ends of the legs causes an electrical voltage (thermal voltage) between the two thermoelectric materials due to the thermoelectric effect. When the circuit is closed then flows an electric current. A TEC may be constructed of several such Peltier elements, which may be connected in series and / or in parallel to achieve a higher temperature or higher current. In most cases, a combination of both interconnections is used. When connected in series, there is a contact area on both sides of the legs, which must be electrically isolated from the other legs.

Peltier elements are used, for example, for cooling coolers for camping and for cooling processors.

frei. Das Vorzeichen von Ẇ hängt von der Stromrichtung ab. Ein negatives Vorzeichen von Ẇ bedeutet, dass dem Kontakt zwischen beiden Leitern Wärme entzogen wird. Es handelt sich, im Gegensatz zur Erzeugung Joulescher Wärme, um einen reversiblen Prozeß.An electric current of current intensity I sets the amount of heat at the interface between two different conductors A and B with the Peltier coefficients PiA and PiB (Equation 1) $$\dot{W}={\mathrm{\Pi }}_{\text{FROM}}\text{I}=\left({\mathrm{\Pi }}_{\text{A}}-{\mathrm{\Pi }}_{\text{B}}\right)\text{I}$$

free. The sign of Ẇ depends on the current direction. A negative sign of Ẇ means that heat is removed from the contact between the two conductors. It is, in contrast to the generation of Joule heat, a reversible process.

The Peltier effect is due to the fact that in a homogeneous conductor of constant temperature with an electric current also flows a heat flow at the same time. Its size is given by π • I. The Peltier heat (Equation 1) represents the excess or deficit between the heat flowing in and out at the contact point. This isothermal heat flow is caused by the fact that not all conduction electrons have the same flow velocity in an electric current. The latter depends on the energy of the electrons. For example, if the conduction electrons with a higher energy than their chemical potential (see below) receive a higher velocity than those with lower energy, the electric charge current is associated with an oppositely directed heat flow because of the negative sign of the electron charge. The Peltier coefficient is then negative. The same is true for a doped semiconductor in which the electric current of electrons is carried in conduction band states.

die aber erst im Rahmen der kinetischen Theorie für die Leitungselektronen oder der Theorie der irreversiblen Thermodynamik gültig begründet werden konnte. Die Kelvin-Relation (2) verknüpft die Materialkonstanten für zwei ganz verschiedene physikalische Effekte, von denen der eine (Peltier-Effekt) die oben angedeutete einfache Erklärung besitzt.Between the absolute thermo power Q and the Peltier coefficient π of a conductor, the relation already found by Kelvin (equation 2 ) $$\mathrm{\Pi }=\text{T}·\text{Q}.$$

however, this could only be validly justified within the framework of the kinetic theory for the conduction electrons or the theory of irreversible thermodynamics. The Kelvin relation (2) combines the material constants for two very different physical effects, one of which (Peltier effect) has the simple explanation given above.

A heat pipe is a gas-tight, sealed component that can be used to transport thermal energy and / or heat very efficiently from one location to another. It can transport 100 to 1,000 times higher thermal energy than a component of the same geometric dimensions made of solid copper. The heat pipe uses the physical effect of converting very large amounts of energy when vaporizing and condensing a liquid. Furthermore, the heat pipe is hollow from the inside and filled with a small amount of liquid, the "working" liquid. This is under its vapor pressure, which can be well below the atmospheric pressure at low temperatures. The inner wall of the heat pipe can be covered with a capillary structure - comparable to a wick. This capillary structure is saturated with a liquid heat transport medium, the "working" liquid.

If energy is supplied at one point of the heat pipe, the "working" liquid from the capillary structure evaporates there. The steam flows in the direction of the temperature gradient and condenses everywhere, releasing the heat of vaporization, where energy is dissipated. The condensate, the liquefied heat transfer agent, is absorbed by the capillary structure and flows back to re-evaporate. It closes a cycle that quickly circulates and very effectively transports thermal energy. The temperature difference between the evaporation and condensation zone in the heat pipe is very low.

Depending on which temperature range is used, different "working" liquids are used, such as water in the temperature range of about 170 to 600 ° K, ammonia in the temperature range of about 150 to 170 ° K, mercury in the temperature range of 400 to 800 ° K. or lithium or silver in a temperature range above 1000 ° K.

Heat pipes can be used for example in TEC / heat pipe cooling systems.

From German patent application DE 10 2011 056 877 A1 a device for the conversion of thermal energy into electrical energy is known. This comprises at least one source of thermal energy, at least one heat pipe, at least one thermoelectric element and at least one heat dissipating device, wherein the heat pipe with its one end in thermally conductive contact with the source of thermal energy and with its other end in electrically insulating, thermally conductive contact with is the hot side of the thermoelectric element and wherein the hot side opposite cold side of the thermoelectric element is in electrically insulating, thermally conductive contact with the heat dissipating device. As heat sources or sources of thermal energy are flat collectors, vacuum tube collectors, photovoltaic cells, solar cells, radiators, components of stoves and underfloor heating, current transformers, the underside of automobiles, engine blocks, exhaust systems, flue pipes, exhaust stacks, containers with materials that generate thermal energy during the phase transformation , electrical resistors, hot water bags, biogas plants, human and animal bodies or solar concentrators.

Cycle and large surface heating called. From the hot side of the thermoelectric element, the thermal energy can be transported through heat pipes to the heat-dissipating devices.

In the above publication, there are no suggestions or indications as to whether the known device is suitable for cooling systems of closed electrical and electronic components and devices without contamination of the interior of the components and devices.

From the American patent application US 2017/0199554 A1 For example, a device for cooling a graphics processor (GPU) and a central processor (CPU) is known in which a TEC is located at a distance from the processors. The cold side of the TEC is thermally bonded to the processors with a thermally conductive plate of iron, aluminum or an iron / aluminum alloy. The heat is conducted from the hot side of the TEC via a heat pipe to a heat sink. The heat sink comprises a plurality of fans each having an air inlet and an air outlet. There is still the danger of contamination of the electrical and electronic components inside the computer.

As further materials are mica or slices of alumina-beryllium oxide ceramic into consideration.

The operation and the structure of the heat pipes are already explained at the beginning. It should be explained in more detail that the materials of which the heat pipes are constructed must be gas-tight, chemically stable, mechanically and thermally stable, as well as resistant to deformation, vis-à-vis both the "working" liquid and the external atmosphere. In addition, the heat pipes should preferably have a high thermal conductivity, at least in those areas in which the thermal energy is absorbed and / or emitted. The other areas of the heat pipes need not be thermally conductive.

The heat pipes can have a wide variety of lengths, which are directed in particular to their intended use and the dimensions of the components and devices according to the invention.

Furthermore, the heat pipes may have different cross sections such as squares, rectangles and triangles, which may have rounded corners and / or sides, ellipses, ovals and / or circles. The size of the cross sections may vary widely and also depends on the intended use of the heat pipes and the dimensions of the components and devices according to the invention.

The heat pipes may have different shapes in the longitudinal direction. So they can straight, in the plane bent once or several times, spatially multiple curved, meandering or spiral.

In addition, the heat pipe heat conductors can be coated after shaping to protect them from mechanical, chemical and / or thermal impact. Examples of suitable coating materials are thermal and / or actinic radiation, e.g. UV radiation or electron beam curable, pigmented and / or non-pigmented powder coatings and / or water-based and / or organic solvent-based fluids.

The capillary structure with wicking on the inside of the walls of the heat pipes can also be made of different materials. The person skilled in the art can therefore select the materials on the basis of the property profiles known to him. The capillary structure can be constructed of nanoparticles, fiber materials and / or nano- and / or microporous materials with appropriately sized pore sizes. In addition, the wicking may be by wire mesh, such as copper wire mesh or electrically non-conductive wire mesh and fiber bundles, e.g. made of ceramic, glass and / or high temperature resistant plastics, are produced inside the heat pipes. Furthermore, the wicking effect may also be due to surface structures of protrusions and pits such as e.g. Grooves, columns, balls and / or wells are generated on the inner walls of the heat pipes. The capillary structure with wicking can also be introduced later. Examples of suitable methods are the crystallization or precipitation of mesoporous materials such as zeolites.

The end of the heat pipes, which is in heat-conducting contact with the component or device according to the invention, is preferably electrically insulated therefrom. For example, the heat-conducting contact between the end of the heat pipe and the component or device according to the invention by solder contacts, welding contacts, flange contacts, electrical and thermally conductive. Adhesive layers containing metal particles, screwed, plugged and clamped contacts, in which the end of the heat pipe is screwed into the source or the source of thermal energy and / or screwed in, plugged in and / or clamped on, pressure contacts, in which the End of the heat pipe is pressed by suitable means to the source of thermal energy produced. The thermally conductive contact can be improved, for example, by the above-described electrically insulating thermally conductive ceramics and thermal compounds.

Heat pipes can be obtained, for example, from the companies Situs Technical GmbH, Wuppertal, Adeo Heatpipe, Switzerland, or Cool Tec Electronic GmbH.

The dimensions and constructive details of the at least one device for conducting the heat given off depend primarily on the amount of heat that has to be dissipated. The person skilled in the art can therefore calculate the most suitable construction for each individual case on the basis of his general knowledge and assemble their components.

Another essential component of the at least one component and / or device according to the invention is at least one device for dissipating the heat from the hot side of the at least one Peltier element to the outside of the closed housing and to a heat sink in the vicinity of the at least one component according to the invention and / or device.

The at least one Peltier element can not stand in a direct heat-conducting, electrically insulating contact with the at least one component and / or device according to the invention. Such a Peltier element can be arranged in the interior of the closed housing on at least one inner side and / or in an opening in the wall of the closed housing, wherein the at least one Peltier element seals the opening in addition to its cooling function

Preferably, the at least one device for dissipating the heat from the hot side of the at least one Peltier element comprises the materials and devices described in detail above and / or at least one arrangement of air slots with microfilters covered by a heat-conducting plate on the inside of the closed housing. The heat conductive plate is preferably a ceramic plate or polyimide film. But it can also be used with polyimide coated metal plates.

If the at least one Peltier element is in direct heat-conducting, electrically insulating contact with the at least one component and / or device according to the invention, as at least one device for dissipating the heat from the hot side of the at least one Peltier element can be described in detail above Materials and devices are used.

In addition, the heat dissipated from the closed housing can be removed in the form of a heated air stream and directed or sucked into central venting systems. For this purpose, suction tubes can be connected to the at least one exit point of the heat.

The devices described above for dissipating the heat from the hot side of the at least one Peltier element and the means for directing the heat given off to the cold side of the at least one Peltier element can be combined in any suitable manner, which requires a large number of Degrees of freedom in the construction of the components and devices of the invention opened.

All components and electrical connections that lead into and / or out of the closed housing are provided with gas-tight and liquid-tight seals, so that the ingress of contaminants is prevented.

Finally, the heat emitted by the at least one component and / or device according to the invention is supplied to a heat sink in the vicinity of the device. This can be an energy harvester, ie a device for converting heat energy into electrical current, such as a thermoelectric element (TEE). In addition, refrigeration units, heat exchangers, tube coolers, or organic and inorganic gases, liquids and phase change materials as mentioned above can be used.

The components and / or devices according to the invention can have a customary and known, mechanical, electrical, electronic and / or pneumatic measurement and control peripheral. In addition, they may include controls and audible and / or visual indicators that screens.

The of the electronic device 1 heat generated heated the protective gas, that of a fan 4.2 as heated inert gas stream 7 sucked and on the cooling fins 4.3 was blown out of aluminum. The cooling fins 4.3 were in electrically insulating, thermally conductive contact with the cold side 3.1 of the Peltier element 3 to which a regulated electrical voltage has been applied. The Peltier element 3 was with his hot side 3.2 stuck to the inside 2.1 of the housing 2 electrically isolated connected. The heat conduction to the the outside 2.2 located layer of thermal compound 5.4 was from the layer of thermal grease 4.4 between the hot side 3.2 and the inside 2.2 accepted. The thermal compound 5.4 transferred the heat to the outside 2.2 attached cooling fins 5.3 from where you use the fan 5.2 was sucked off. The resulting heated air flow 7 was from the fan 5.2 in a suction tube 5.8.1 (not shown, cf. 5 ) as a heat sink 6 , which is gas-tight with the outside 2.2 of the housing 2 was connected and the fan 5.2 , the cooling fins 5.3 and thermal grease 5.4 included, blown.
