Definitions
- the invention relates to a heat transfer device for heat transfer from a heat source to a heat sink, which has at least one contact device for thermal contacting of at least parts of the furnishedübertragungsvorhchtung with the heat source and / or the heat sink and at least one heat conducting device for transmitting thermal energy between the heat source and the heat sink.
- the invention further relates to a device arrangement which has at least one heat source, at least one heat sink and at least one heat transfer device. Furthermore, the invention relates to the use of a heat transfer device and / or a device arrangement.
- Highly sensitive detectors for example, often have to be operated at very low temperatures to avoid thermal noise. Temperatures in the range of liquid nitrogen (about 77 Kelvin) and / or temperatures in the range of liquid helium (about 3 Kelvin) are frequently used as suitable operating temperatures. In order to be able to provide the thermal energy removal provided by a suitable cooling system even at the high-sensitivity detector, heat transfer devices with a suitable heat transfer capacity are required. At the same time, however, highly sensitive detectors must also be stored with as little vibration as possible. A particular problem is that cooling devices which have a correspondingly low temperature often produce a particularly high level of vibration.
- a currently common design in detector construction is that the actual detector is thermally connected to a cooling device via a thick, multi-core, elastic copper cable.
- the copper cable often has conductor cross sections in the range of 1 cm 2 and more.
- the multicore copper cable acts as a damper, so that the vibrations of the cooling device are largely attenuated and largely kept away from the detector. Nevertheless, a sufficient cooling capacity of the detector is usually realized.
- the multicore copper cable is usually connected to a cold finger, which dips into a bath of liquid nitrogen and / or a bath of liquid helium. This bath is supplied by a corresponding chiller with a sufficient amount of liquid nitrogen or liquid helium.
- a suitable copper alloy, aluminum or a suitable aluminum alloy is used instead of copper.
- a problem with the method described for cooling the high-sensitivity detector is the thermal contact resistance between the individual components along the heat transfer path.
- the thermal To minimize transition losses contact elements have been proposed, which are on the one hand connected to the copper cable, on the other hand as possible flat with the cooling device or with the detector (optionally with the aid of a cold finger).
- the contact elements are usually designed so that they cause an intimate mechanical contact of the two thermally interconnected components. This intimate mechanical contact can be formed for example by a kind of plug-in elements. In such a structure, however, there are still thermal transition losses, in particular between the contact device and the copper cable itself.
- One measure for example, is to thermally connect the contact device to the copper cable as effectively as possible by so-called "crimping." In reality, this is usually achieved by providing a hole in the contact device into which the copper cable is inserted Inner diameter is reduced by a compression of the contact device, so that there is a positive contact between the contact device and the copper cable.However, it has been found that this crimping often does not sufficiently reduce the thermal contact resistance between contact device and copper cable.
- thermodynamic adhesive which is placed between the contactor and the copper cable to reduce the thermal contact resistance.
- some thermodynamic adhesives, such as indium have proven to be sufficiently durable, adequately durable thermodynamic adhesives are generally very expensive and / or toxic, which is correspondingly problematic.
- soldering and welding processes are known.
- these methods are relatively complex and cause by the additional masses introduced an increase in weight or a thickening of the corresponding materials, which is undesirable, especially in the field of cooling of relatively freely suspended assemblies.
- soldering or welding seams often prove to be insufficiently stable in temperature, especially at kyrostatic temperatures.
- Another problem may be in the form of the strength of the components to be used. While, for example, when soldering electrical conductors, it is generally sufficient to connect cables with a conductor diameter of, for example, 1 mm 2 to a contact surface, such cross-sectional areas are generally insufficient for cooling purposes.
- the soldering and / or welding of conductors with cross-sectional diameters of several cm 2 is usually complex and technologically difficult to control.
- the object of the invention is therefore to provide a heat transfer device for heat transfer from a heat source to a heat transfer device. valley, which has improvements over heat transfer devices known in the art.
- a heat transfer device for heat transfer from a heat source to a heat sink, which has at least one contact device for thermal contacting of at least parts of the heat transfer device with the heat source and / or the heat sink and at least one heat conduction device for transmitting thermal energy between the heat source and the heat sink to further develop that at least one heat conducting device and at least one contact device are at least partially connected to one another by an ultrasonic welding process.
- a further advantage may also result from the fact that the processed by an ultrasonic welding heat conduction device (for example, a multi-core copper cable) usually has a significantly lower tendency for splicing. This also makes it possible to avoid unwanted thermal bridges.
- the ditchleitein- direction can serve in any way only the heat conduction, but also optionally in addition to the transmission of electrical signals (bei- For example, to power a detector device) can be used. However, it is generally advantageous (especially in the case of highly sensitive detector systems) if the heat-conducting device is used exclusively for heat conduction and not additionally for the transmission of electrical signals.
- the heat conducting devices can have a high heat transfer cross section. This heat transfer cross section may in particular also be provided in the contacting region with a contact device.
- the heat conduction device makes it possible, in particular, for the heat conduction device to have a substantially identical heat conduction cross section over its entire length, which can simplify the manufacture of the heat transfer device.
- the heat-conducting device has different cross-sectional diameters along its longitudinal extent.
- the heat conduction device is elongated (for example in the form of a multi-core cable) .
- the contact devices can then be arranged on the end regions of the elongate heat conduction device.
- the heat-conducting device is at least partially elastic and / or flexible, in particular vibration-elastic and / or vibration-flexible. In this way, it is possible, in particular, to achieve a particularly good mechanical decoupling of the two devices, which are thermally coupled to one another via the heat transfer device. In addition, it is possible to compensate for certain bearing tolerances between the two devices.
- the heat transfer device at the same time as a kind of "angle element." Since the angle is not necessarily fixed, the heat transfer device can be used in a particularly large number of situations, among other things the storage costs or the production costs reduce the device in which the heat transfer device is used.
- the heat conducting device is at least partially designed as a multi-core cable, which in particular at least partially copper, a copper alloy, aluminum and / or an aluminum alloy.
- a multi-core cable which in particular at least partially copper, a copper alloy, aluminum and / or an aluminum alloy.
- standard components can be used.
- multi-core cables made of copper, copper alloy, aluminum and / or aluminum alloy in the field of power engineering are widely used.
- Such components can be used without problems for the proposed heat transfer device.
- the proposed materials have a particularly high heat conduction at a particularly favorable price.
- materials other than those mentioned, which should preferably have the highest possible heat conductivity are also possible to use the heat transfer device.
- the heat conducting device in a particularly simple manner elastic and / or flexible (including vibration elastic and / or flexible vibration) form. Also, bends can be realized in a particularly simple manner.
- a support surface or more support surfaces
- the ultrasonic welding process is particularly simple can be carried out.
- a single heat conducting device is provided.
- a single heat conduction device is to be understood in particular as a device which is connected in a largely uniform and / or contiguous contacting region with a heat contact device. Accordingly, it is also possible that a single heat conducting device consists of a plurality of subcomponent th (such as several juxtaposed multicore cables) may be formed.
- At least one support surface is provided in the heat-transfer device, which is preferably arranged diametrically opposite to at least one heat-conducting device.
- a combination of a welding sonotrode and a welding anvil can be used.
- the welding sonotrode generally contacts the heat conducting device to be connected to the contact device, while the supporting surface is usually in contact with an ultrasonic welding boss during the ultrasonic welding process.
- the proposed diametrical arrangement can realize a particularly effective "straight-line" ultrasonic welding process
- the contacting section can have an n-cornered shape in particular in cross-section, wherein the n-corner is preferably a symmetrical geometric body with an odd number of corners
- the geometric base body for example a triangle
- Heat transfer device be extended to technical fields, in which a high heat transfer, and in which, if necessary, in addition a good mechanical decoupling is needed.
- the proposed design of the heat transfer device using an ultrasonic welding process proves to be of great importance in terms of design as a rule for low-temperature suitable or lowest temperature suitable applications. In particular, temperatures in the range of liquid nitrogen and / or in the range of liquid helium are manageable.
- At least parts of at least one heat conduction device and / or at least parts of at least one contact device have a heat transfer cross section of at least 5 mm 2 , 10 mm 2 , 15 mm 2 , 20 mm 2 , 25 mm 2 , 30 mm 2 , 40 mm 2 , 50 mm 2 , 60 mm 2 , 70 mm 2 , 80 mm 2 , 90 mm 2 or 100 mm 2 .
- Such heat transfer cross sections have proven to be advantageous in order to realize a high heat coupling. Nevertheless, it is possible to realize a good mechanical coupling despite the high heat transfer performance.
- a device arrangement which has at least one heat source and / or at least one heat sink, and in which at least one heat transfer device according to the above description is used.

- the shape of the connecting region 4 of the contacting elements 3 is illustrated in FIG. 2 in a cross-sectional view (cross section perpendicular to the axial direction of the thermal conductor 1). Fig. 2 will be explained in more detail below.
- connection between the heat-conducting elements 2 and the respective contacting element 3 takes place using an ultrasonic welding method. Further details for carrying out the ultrasonic welding process are shown in particular in FIG. 3 and the associated description (described below).
- the heat-conducting elements 2 are intimately and materially connected to the contacting elements 3 with the aid of the ultrasonic welding process. This type of connection leads to particularly low heat transfer resistance between the contacting elements 3 and the heat-conducting elements 2 and thus ultimately to a particularly good heat conduction between the spaced-apart thermo-fingers 5.
- Both the contacting elements 3, and the heat-conducting elements 2 are made in the present embodiment of copper or a copper alloy. It is not necessary, moreover, that the contacting elements 3 and the heat-conducting elements 2 each have to be made of the same material. Rather, it is preferred that the heat-conducting elements 2 on the one hand and the contacting elements 3 on the other hand are each made of a different material (in particular of a different alloy). If appropriate, it is also advantageous if the two contacting elements 3 each consist of different materials (in particular of different alloys). In this way, the two contacting elements 3, for example, particularly well to the adjacent theretogruordnenten Components are adapted so that in this way, for example, particularly good material incompatibilities can be avoided.
- the contacting elements 3 are preferably substantially solid (in particular in the region of the connecting regions 4).

- the banksleitense 2 as quadriges cable can be prevented by the ultrasonic welding between the heat conducting elements 2 and the contacting elements 3 advantageously splicing of the heat conducting elements 2.
- This can prevent, for example, premature wear of the thermal conductor 1.
- the formation of undesirable thermal bridges and / or unwanted electrical contacts with other parts of the resulting device can be avoided. Both are naturally beneficial.
- Due to the elastic design of the heat-conducting elements 2, the two contacting elements 3 can be mechanically decoupled from each other in a wide range. The same applies to the devices which are attached to the remote contacting elements 3. Nevertheless, a very good thermal coupling between the two contacting elements 3 can be realized by the construction of the thermal conductor 1.
- thermal conductor 2 is in particular also in its compact construction. This concerns in particular its dimensions in the radial direction.

- the middle region 9 of the triangular limb 23 of the triangular basic shape 6 serves in each case as a contacting region 10, in which in the presently illustrated embodiment in each case a heat conducting element 2 is fastened by ultrasonic welding (see also FIG.
- a plurality of contacting regions 10 to be provided in a central region 9, so that a plurality of heat-conducting elements 2 can also be attached in the region of a single triangular limb 23.
- the triangular tips 1 1 of the triangular basic shape 6 are capped.
- the remaining length of the central region 9 is about 2/3 of the original edge length of the triangle sides 23 of the triangular basic shape 6.
- the "cut edge length" of the triangular tips 11 each 1/6 of the original edge length of the triangle legs 23 of the triangular It is, of course, also possible to carry out a different division, In particular, it is possible to adapt the dimensioning as a function of the size of the heat-conducting elements 2.

- the cut surface 12 thereby serves as a support surface 12 for carrying out the ultrasonic welding process.
- the Ultraschallsch spaso- notrode 13 and the ultrasonic welding anvil 14 are not simultaneously, but in succession with the connection portion 4 into contact. In principle, it is arbitrary whether first the ultrasonic welding robot 13 or the ultrasonic welding anvil 14 is put on.
- the ultrasonic welding process with which the heat-conducting element 2 is welded to the contacting region 10 of the contacting element 3, is carried out.
