- the user 10 comprises, for example, a magnetic field generator obtained using a superconducting magnet and / or one or more pumping units. by cryo-condensation or any other organ requiring cooling at a very low temperature.
- the device further comprises, in a manner known per se, an additional pre-cooling system of the working gas at the outlet of the compression station 2.
- the pre-cooling system comprises a capacity 3 of auxiliary cryogenic fluid such as liquid nitrogen.
- the capacitor 3 is connected to the working circuit via at least one heat exchanger for selectively transferring frigories of the auxiliary fluid to the working gas.
- the capacity 3 can be supplied with auxiliary fluid via a supply line 13 connected to a source of auxiliary fluid (not shown) and provided with a valve 23 (cf. figure 3 ).
- the compression station 1 comprises two compressors 11, 12 in series defining for example three pressure levels for helium.
- the compression station 2 may also include helium purification organs 8.
- the helium is admitted into a cold box 2 in which this helium is cooled by heat exchange with several exchangers 5 and in which it is expanded in turbines 7.
- the liquefied helium in the cold box 2 can be stored in a reserve 14 provided with an exchanger 144 for heat exchange with the user 10 to cool (for example via a circuit provided with a pump).
- This heat exchange system 14 between the helium and the user 10 may comprise any other appropriate structure.
- the low-pressure helium that has passed through the heat exchange system 14 is sent back to the compression station 1 via a return line 9 in order to restart a work cycle. During this return, the relatively cold helium transfers heat to the heat exchangers and in this way cools the relatively hot helium which is cooled and expanded in the opposite direction before reaching the user 10.
- the working circuit may comprise a return line 19 returning to the station 1 for compressing the helium of the cold box 2 that has not passed through the heat exchange system 14.

- This first cooling stage comprises a first heat exchanger and a second heat exchanger connected both in series and in parallel to the working circuit at the output of the compression station 1. That is, the working gas leaving the compression station 2 can be selectively admitted into the first and / or second heat exchanger.
- the first heat exchanger is for example of the heat exchange type between different streams of helium at different respective temperatures.
- the first heat exchanger may comprise a first fed passage 6 in high-pressure hot working gas coming directly from the compression station 1, a second countercurrent passage of the first passage and supplied by the gas return pipe 9 working said cold and low pressure and a third passage against the current of the first passage and fed medium pressure working gas via a return line 19.
- the second heat exchanger is of the heat exchange type between the working gas and the auxiliary gas and comprises, for example, a first feed gas passage 16 of working gas from the first heat exchanger and / or directly from the can. 2, a second passage, countercurrent to the first passage and provided for vaporized auxiliary gas, and a third passage supplied with working gas via the pipe 125 recovery.
- the first cooling stage also comprises a third heat exchanger 25.
- This third heat exchanger is connected at the same time in series and in parallel with the first 5 and the second 15 heat exchanger. That is, the working gas exiting the first and / or second heat exchanger is selectively admitted into the third heat exchanger. As illustrated for example in more detail at figure 3 this is achieved by connecting a fluid inlet of the third heat exchanger to two fluid outlets belonging respectively to the first and second exchangers 15.
- the working circuit comprises a recovery line 125 which selectively connects the outlet of the third heat exchanger 25 to the second heat exchanger, for selectively permitting the transfer of frigories from the working gas exiting the third heat exchanger 25 to the second heat exchanger 15.
- the working circuit comprises a limited portion subdivided into two parallel lines, one of the two lines constitutes the recovery line 125.
- This circuit portion may comprise a set of valve (s) 225, 44 to ensure a selective distribution of helium between the two parallel lines (cf. figure 3 ).
- recovery line 125 after its transit through the third heat exchanger 25, is connected downstream to the working circuit of the cold box 2 in order to continue the cooling of the working gas.
- the third heat exchanger is selectively supplied with auxiliary fluid (nitrogen, for example).
- auxiliary fluid nitrogen, for example.
- the third heat exchanger 25 is a heat exchanger remote from the capacitor 3 and selectively supplied with auxiliary fluid via a circuit comprising at least one supply line 13. This makes it possible to selectively transfer frigories of the auxiliary fluid to the helium within the third heat exchanger.
- the device preferably comprises a pipe 225 for evacuating the vaporized auxiliary gas connecting an upper end of the capacitor 3 to a remote recovery system via a passage in the second heat exchanger. This allows selectively transferring frigories of the vaporized auxiliary gaseous fluid to the working gas passing through the second heat exchanger.
- the figure 3 illustrates an alternative embodiment of the first cooling stage of the device.
- the embodiment of the figure 3 is different from that of figure 2 only in that the third heat exchanger 25 is this time immersed in the auxiliary fluid capacity.
- the Figures 4 to 6 are three distinct configurations that can be used in a succession of an example of possible operation of the device.
- a first phase of cooling a user illustrated in the figure 4 the helium from the compression station 1 is sequentially cooled in series in the first 5, second 15 and third 25 heat exchangers (valves 116 and 126 closed, valve 136 open).
- the cooled helium returns to pass through the second heat exchanger via the recovery line 125 (valves 225 and 44 open).
- the auxiliary fluid (nitrogen) at a temperature of about 80 K is allowed to circulate in the second heat exchanger (it comes out for example at a temperature of about 270 K).
- a second cooling phase of the user having a temperature of 200K can comprise the same configuration as that of the figure 4 .
- the auxiliary fluid (nitrogen) at a temperature of about 80 K is allowed to circulate in the second heat exchanger and comes out, for example, at a temperature of about 190 K.
- a third cooling phase of the user having a temperature of 140K can comprise the same configuration as that of the figure 4 .
- auxiliary fluid nitrogen
- the second heat exchanger the auxiliary fluid (nitrogen) at a temperature of about 80 K is allowed to circulate in the second heat exchanger and it emerges, for example, at a temperature of about 140 K.
- a fourth phase of cooling the user with a temperature of 120K may have a configuration that differs from that of the figure 4 only in that the helium leaving the third heat exchanger is not recirculated in the second heat exchanger (valve 225 closed).
- the auxiliary fluid (nitrogen) at a temperature of about 80 K is allowed to circulate in the second heat exchanger and comes out, for example, at a temperature of about 120 K.
- the device can adopt a fifth phase of operation illustrated in FIG. figure 6 .
- This fifth phase of operation differs from the configuration of the figure 5 only in that the helium from the compression station 1 is distributed between the first 5 and second 15 heat exchangers (valves 116 and 126 closed while the valve 136 is open).
- the auxiliary fluid (nitrogen) at a temperature of about 80K is allowed to circulate in the second heat exchanger and it comes out for example at a temperature of about 300K.
- the architectures described above thus make it possible to cool a massive component of a relatively hot temperature (for example 300K at a relatively low temperature (for example 80K) with the same number of equipment as necessary for normal (nominal) operation. refrigerator / liquefier.
- the three heat exchangers 5, 15 and 25 may advantageously be heat exchangers of the same type, for example aluminum plates and fins. This makes it possible to use compact heat exchangers 5, 15, 25 and efficiently for all the operating modes of the device (cooling or normal operation).
- This architecture makes it possible in particular to reduce the size of the first heat exchanger with respect to known systems.
- this first heat exchanger only receives helium (no nitrogen).
- the flow of helium at high pressure can be reduced in part by distributing a portion of this helium in the second heat exchanger.
- the relatively hot and cold helium flow rates are not completely balanced, that is to say that the cold flow rates induce an increase in the pinch, that is to say an increase in the minimum temperature difference.
- the cold fluids and the hot fluids along the exchanger and an increase in the "LMTD" i.e., an increase in the logarithmic mean of the temperature differences of the heat exchanger.
- the frigories brought by the cold flows become more important than the calories to be extracted from the hot flow. The cold flow rates therefore undergo less warming, hence the increase in the LMTD of the heat exchanger.
- This arrangement makes it possible to reduce the temperature differences at the second heat exchanger due to the helium transferred to the second changer 15 via the recovery line 125.
- This helium from the recovery line 125 is reheated by yielding frigories to the second heat exchanger and is then mixed with the relatively cold helium flow which flows downstream into the cold box.
- the device has many advantages over the prior art.
- the device makes it possible in particular to size the first 5, second 15 and third 25 exchangers for the normal operation of the refrigerator and can thus be constituted by aluminum exchangers with plates and fins.
- the device also allows the helium temperature to be regulated in a simple and effective manner depending on the operating mode.
