Definitions
- Cooling system with a hot and a cold connection element and a heat pipe connected to the connecting elements
- the invention relates to a refrigeration system having at least one hot connection element, which is thermally connected to parts of a device to be cooled, a cold connection element, which is thermally connected to a heat sink, a heat pipe made of poorly heat-conducting material, which at a first end with the warm connection element and at a second end to the cold connection element is connected, and whose interior is at least partially filled with a circulating after a thermosiphon effect liquid.
- Cooling systems e.g. Cooling systems for superconducting magnets often have so-called bath cooling.
- a liquid refrigerant e.g. Helium
- DE 10 2004 060 832 B3 discloses an NMR spectrometer whose superconducting magnet coil system has bath cooling.
- the cooling system of the NMR spectrometer is designed such that a circulating refrigerant detects various elements of the NMR spectrometer in its circulation path. By means of such a refrigerant circulation, a multiplicity of elements of the NMR spectrometer with different temperature levels can be cooled by means of a single refrig- erator.
- cooling systems are designed without a refrigerant bath.
- Such cooling systems can do without any refrigerant.
- the cooling capacity is introduced in this case only by solid-state heat conduction in the areas to be cooled.
- the areas to be cooled may be replaced by a so-called solid state cryobus of e.g. Copper connected to a chiller.
- Another possibility is to connect the areas to be cooled and the chiller to a closed piping system in which a small amount of refrigerant circulates.
- the advantage of such cooling systems without a refrigerant bath continues to be that they are easier to adapt to moving loads to be cooled as cooling systems, which have a refrigerant bath.
- Cooling systems without a refrigerant bath are therefore particularly suitable for superconducting magnets of a so-called gantry, as used in ion beam therapy for combating cancer.
- the cooling capacity can be provided in the cooling systems described above typically a chiller with a cold head in particular a Stirling cooler available.
- a superconducting magnet in which a cold head with its second stage is directly mechanically and thermally connected to the support structure of a superconducting magnet winding can be seen for example from US Pat. No. 5,396,206.
- the necessary cooling capacity is directly transferred to the superconducting magnet by means of solid-state heat conduction in the superconducting magnet. introduced magnetic coils.
- the abovementioned cooling device for a superconducting magnet has a decisive technical problem.
- air or other gases may freeze at the cryogenic contact surface, in this case the superconductive winding support structure. Ice formed at these points leads to a poor thermal connection of the subsequently reused cold head with the holding structure of the winding.
- the freezing of ambient gases at the deep-cold contact surfaces can be avoided by purposely flooding the space around these contact surfaces with gas.
- this is expensive and leads to a large consumption of purge gas or vaporized refrigerant for this purpose.
- EP 0 696 380 B1 discloses a superconducting magnet with a cryogen-free refrigeration system.
- the disclosed refrigeration system has a thermal bus of good thermal conductivity material such as copper, which is connected to the superconducting magnet.
- the thermal bus can still be connected to two cold heads.
- the two cold heads are arranged symmetrically to the thermal bus. They can each be approached from opposite sides to the thermal bus. In this way one or both cold heads can be Fe be brought into thermal contact with the thermal bus.
- the cooling capacity is introduced in accordance with one or both cold heads in the thermal bus.
- JP 2000-146333 A discloses an apparatus and method for maintaining a cryocooler. Before replacing a cryocooler or cold head, a corresponding identical one is used
- Cold head pre-cooled in a bath with liquid nitrogen.
- the components of the cold head can be brought to a comparable temperature as the corresponding components to be replaced. In this way, the cryogenic conditions within a plant whose cold head is to be replaced, can be kept almost unchanged.
- DE 102 11 568 B4 discloses a refrigeration system with two cold heads, which are connected to the parts of a device to be cooled via a piping system in which a refrigerant can be circulated according to a thermosiphon effect.
- the piping system has a branch. At each end of the branches there is a refrigerant space, which is connected to a cold head. Liquid refrigerant decreases, starting from one of these refrigerant chambers, gravity driven to the parts of the device to be cooled, at which the heat transfer takes place. Gaseous refrigerant rises in the piping system again to the two cold heads, where it is reliquefied.
- Such a cycle of the refrigerant may take place in the piping system both in the case where only one cold head is operating and in the case where both cold heads are operating. If the refrigeration system is dimensioned in such a way that a single cold head applies the cooling capacity necessary for the parts of the device to be cooled, another cold head can be exchanged during operation of the refrigeration system. This is to minimize thermal losses
- DE 101 04 653 A1 discloses a mechanical heat switch, which consists of a first cup-shaped metal body, which can enclose a second metal body in a form-fitting manner.
- the first metal body has for this purpose a free end which, together with the outer jacket of the second
- Metal body can form a positive connection.
- a fourth metal body is introduced, a third metal body surrounds the cup-shaped first metal body from the outside surrounding. Upon heating of the fourth metal body, this expands and presses against the inner wall of the pot of the first metal body such that the free end of the first metal body moves and thereby releases the connection to the second metal body. In this way, the thermal contact between the first and the second metal body can be opened.
- the third metal body which surrounds the first metal body and forms a ring, contracts and presses the free end of the first metal body. gene the second metal body. In this way, the thermal switch can be closed.
- the object of the present invention is to specify a refrigeration system in which the parts of a device to be cooled are connected to a heat pipe in which a liquid can be circulated by a thermosyphon effect, with a heat sink, wherein the parts to be cooled of a device should be largely thermally decoupled from the heat sink without a mechanical separation.
- the present invention is based on the following considerations:
- the heat exchange between the heat sink and the parts of a device to be cooled takes place essentially by the liquid which can be circulated in the heat pipe according to a thermosiphon effect.
- the heat pipe can be pumped off via a pipe connected to its interior.
- the heat pipe should be made of a poor thermal conductivity material at the same time.
- the refrigeration system should contain at least one hot connection element, which is thermally connected to parts of a device to be cooled, and a cold connection element, which is thermally connected to a heat sink contain.
- a heat pipe made of poorly heat-conducting material should be connected at a first end to the hot connection element and at a second end to be mechanically detachable with the cold connection element.
- the interior of the heat pipe should be at least partially filled with a liquid which can be circulated according to a thermosiphon effect.
- the refrigeration system should comprise a pipeline which is connected to a first end with the interior of the heat pipe and designed in such a way is that at least parts of the pipeline are geodetically higher than the liquid level.
- the liquid should be able to be pumped out of the heat pipe via the pipeline.
- the thermal contact when reinserting the heat sink will be much better than in the case in which there is significant ice formation at the contact surfaces. Furthermore, the cryogenic region in which the parts of the device to be cooled, due to the thermal decoupling, is prevented from penetrating into this region heat flows. In this way, even when replacing the heat sink to be cooled parts of a device at the desired low temperature.
- a refrigeration system can be specified, which allows even with a single heat sink use, without heating the parts to be cooled is necessary to exchange the heat sink or wait or remove temporarily.
- the refrigeration system according to the invention is particularly suitable for devices in the field of superconducting technology.

- the parts of the device to be cooled can be arranged in an evacuatable cryostat and the second end of the pipeline can be outside the cryostat.
- Deep-frozen parts of a device can be thermally insulated from their environment particularly advantageously by means of an evacuatable cryostat.
- Such a thermal insulation represents a particularly effective insulation for cryogenic parts of a device.
- Refrigeration system according to the above embodiment is therefore particularly advantageous especially for devices with cryogenic parts.
- a multi-stage refrigerator with a first and a second stage, wherein the heat sink may be formed by the second stage and the first stage may be mechanically detachably connected to a disposed within the cryostat heat shield.
- a multi-stage chiller is particularly suitable for cryogenic parts of a device to be cooled. It is particularly advantageous to use a heat shield as a further measure for thermal insulation.
- the thermal separation according to the invention of the parts to be cooled of a device from the second stage of the refrigerating machine is particularly advantageous, since the advantage of a thermal separation without moving parts comes into play particularly in mechanically complex cooling systems.
- At least parts of the refrigeration machine may be interchangeably mounted in an evacuable maintenance space separated from the evacuatable cryostat. With the help of another, separated from the evacuated cryostat, also evacuated maintenance space of the replacement of the chiller can be made without the vacuum of the cryostat must be broken. The maintenance process is particularly simple and effective in this way.
- the liquid may be present as a two-phase mixture.
- circulation of the liquid in the heat pipe may occur, condensing gaseous liquid at the cold end of the heat pipe and vaporizing liquid liquid at the warm end of the heat pipe.
- the latent heat of the phase transition can be used for heat transport.
- a corresponding circulation can also be achieved in a single-phase liquid due to natural convection based on density differences.
- the refrigeration system can be rotatable about an axis which runs essentially parallel to an axis of symmetry of the heat pipe.
- the heat pipe can furthermore have a larger cross-section in a first area, which is connected to the warm connecting element, than in a second area, which is connected to the cold connecting element.
- the parts of the heat pipe connecting the first and the second area may be configured such that condensed refrigerant can freely move to the first area under the influence of gravity in the second area.
- a refrigeration system with the aforementioned features can be used in particular advantageous for movable, in this case rotatably arranged to be cooled parts of a device. Due to the special design of the heat pipe the thermal contact between the chiller and the parts of the device to be cooled is guaranteed at any time even with a rotation of the parts to be cooled of a device.
- the tubing may be connected at its ends near the axis of symmetry of the heat pipe to the heat pipe and the outside of the cryostat.
- the pipeline can furthermore have at least one intermediate axis in the direction of travel.
- the intermediate region of the pipeline can have a V-shaped course in the direction of the axis A.
- a V-shaped bent pipe represents a particularly simple and effective embodiment of the pipeline.
- the heat pipe can be configured substantially in the shape of a truncated cone.
- a particularly simple inexpensive and effective form of the heat pipe can be specified.
- the refrigeration system may comprise an additional cooling system, which has at least the following features: A refrigerant space which communicates with the cold connection element connected is; a supply line through which the refrigerant space can be filled from a geodetically higher location outside the cryostat with a second refrigerant; a piping system which is thermally connected over a large area with the parts to be cooled of the device and in which the second refrigerant is conditionally circulated by a thermosiphon effect; an exhaust pipe through which gaseous second refrigerant can escape from the piping system.
- an additional cooling system with the aforementioned features, an acceleration of the cooling phase can be achieved, in particular for large masses to be cooled.
- evaporating second refrigerant can escape via the exhaust pipe from the piping system.
- the second refrigerant can circulate after a thermosiphon effect, thus providing effective cooling.
- the connecting elements can be made of a good thermal conductive material, preferably of copper.
- the heat pipe may be made of a material having a thermal conductivity less than that of copper, preferably of stainless steel.
- Such a configuration of the connecting elements made of a good thermally conductive material such as copper a special effective thermal coupling can be achieved both to the heat sink as well as to be cooled parts of the device.
- the thermal conductivity of the heat pipe is mainly due to the circulating within the heat pipe refrigerant. If the heat pipe itself is made of a poorly heat-conductive material, such as stainless steel, a particularly large reduction in the thermal conductivity can be achieved by pumping off the refrigerant.
- the device may be a gantry device for radiotherapy, and the parts to be cooled may be the magnets of the gantry for deflecting a particle beam.
- the refrigeration system according to the invention is particularly suitable for a gantry, since the magnets to be cooled are rotated about an axis of rotation of the gantry.
- Figure 2 shows the cross section of a rotatable refrigeration system
- Figure 3 shows the cross section of a rotatable refrigeration system with an additional cooling system.
- FIG. 1 shows the schematic structure of a refrigeration system 100 according to one embodiment.
- a cryostat 108 contains the parts 102 to be cooled of a device.
- the device parts to be cooled 102 may be, for example, the magnet windings of a superconducting magnet or other parts of the superconducting technique.
- a thermal shield 112 is attached inside the cryostat 108 to improve the thermal insulation.
- the cooling capacity for the parts to be cooled 102 of the device is provided by a refrigerator 109, such as a cold head or a Stirling cooler.
- a cold head can be used, which operates on the Gifford-McMahon principle.

- the pipeline 107 has a part 204 bent in the direction of the axis A.
- the liquid 106 can be pumped out of the heat pipe 105 through the pipeline 107. In this way, a thermal separation between the parts to be cooled 102 of a device and the heat sink 104 is achieved.
- the working space 113 is aerated after the liquid 106 has been pumped off.
- the parts of the working space 113 which are arranged between the mounting flange of the first stage 111 of the refrigerator with the heat shield 112 and the condenser 103, can be designed to be flexible. Such a flexible embodiment can be carried out, for example, with the aid of a bellows.
- the condenser 103 may be movable along the axis B due to a flexible configuration of the heat pipe 105.
- the heat pipe 105 may also have a bellows for this purpose.
- Figure 3 shows another embodiment of a generally designated 100 refrigeration system.
- a refrigerant space 301 is in thermal, preferably also in mechanical contact with the cold connection element 103.
- This refrigerant space 301 can be filled by a feed line 302 from a geodetically higher location.
- a same or similar refrigerant can be used as it is used for the heat pipe 105. Usable are, for example, helium, neon or nitrogen.
- a piping system 303 is connected, which is connected over a large area with the parts to be cooled 102 of a device. In this way, additional cooling capacity can be brought to the parts to be cooled 102 of a device.
- evaporating refrigerant can escape via an exhaust pipe 304 from the piping system 303. In this way, an overpressure in the piping system 303 is avoided.
- the auxiliary cooling device may e.g. be used so that the parts to be cooled 102 of a device first with nitrogen, which is inexpensive and readily available, are pre-cooled before using the chiller 109, the parts to be cooled 102 are cooled to even lower temperatures.
- additional cooling device it is technically necessary to stop the refrigeration system 100 in its possible rotation about the axis A, or at least to move so slowly that in the piping system 303, a gravity-driven refrigerant circuit, which is based on a thermosiphon effect, can set ,
