- the first fluid 2 and / or the second fluid 3 is a temperature between -100 ° C and -273 ° C.
- the invention can also be used at room temperature or between room temperature and cryogenic temperatures.
- the heat exchanger 1 is of the polymer microtubes type, that is to say comprising a plurality of polymer microtubes 4 and having a diameter of between 0.1 mm and 1 cm.
- the first 2 fluid is circulated inside said micro-tubes 4 while that the second fluid 3 is circulated around said micro-tubes 4.
- the micro-tubes 4 are preferably non-porous.
- the micro-tubes 4 preferably consist of at least one of the following materials: polyetheretherketone (PEEK), Polytetrafluoroethylene (PTFE), Polyetherimide polyimides, polyamides, polycarbonates, for example a mixture of 50% polyetherimide (“Ultem”) and 50% of Peek and in particular any suitable material compatible with cryogenic temperatures.
- PEEK / Ultem mixture can be extruded in the form of an amorphous material whose glass transition temperature (Tg, or Tg in English) is about 180 ° C.
- Tg glass transition temperature
- This mixture unlike the materials used in the literature, does not require any annealing. In addition, this mixture is essentially non-crystalline, it is quite strong and flexible as it is made.
- Other crystalline materials cited in the literature would have relatively high coefficients of thermal expansion (CTE), some exceeding 80 ppm / ° C.
- CTE coefficients of thermal expansion
- the coefficient of thermal expansion (CTE) of PEEK is 45
- the coefficient of thermal expansion of Ultem is 45
- the coefficient of thermal expansion of the epoxy resin is for example equal to 55.
- This constituent material is compatible with cryogenic temperatures (up to a few degrees Kelvin for example) and can withstand large pressure differentials (which can for example reach of the order of 100 bar).
- the micro-tubes 4 are preferably made of a material having a density less than 2700 kg / m 3 and in particular less than 1500 kg / m 3 and for example between 900 kg / m 3 and 2700 kg / m 3.
- the microtubes 4 preferably have a thickness of between 0.01mm and 1mm, in particular 0.05mm. In addition, the microtubes 4 preferably have a diameter of the order of 0.1 to several millimeters, in particular one millimeter.
- the pressure differential between the pressure of the fluid 2 circulated in the micro-tubes 4 and the pressure of the fluid 3 circulated around the micro-tubes 4 can be between 1 bar and 100 bar and in particular between 10 and 50 bar .
- the heat exchanger 1 may comprise a housing 5 in which the micro-tubes 4 are arranged.
- the housing 5 comprises a first inlet 6 communicating with a first end of the micro-tubes 4 and a first outlet 7 communicating with a second end of the tubes.
- the housing 5 also comprising a second inlet 8 and a second outlet 9 communicating with the volume located around the micro-tubes.
- These two input / output pairs define two independent circuits for two fluids.
- the microtubes 4 can be arranged in a bundle, for example parallel in a longitudinal direction in the housing 5 (and in particular rectilinear or substantially rectilinear), or according to any other geometric configuration.
- the micro-tubes 4 can be wound in a helix and for example distributed in an organized manner around a central support mandrel.
- This helical winding can serve not only to control the packing density of tubes, but also provides a unique mechanism to combat potential dimensional shrinkage of tubes at low temperatures.
- the shrinkage of the tubes due to thermal contraction can potentially exert a stress on the microtubes 4 which will be transmitted to the tubesheet. This stress can lead to a rupture of the bond between the tube sheet material and the individual tubes or, in extreme cases, failure of the tube sheet or the manifold itself.
- the helically wound micro-tubes 4 make it possible to relieve the shrinkage stress by modifying their winding angle in the device.
- the micro-tubes 4 can therefore not be subjected to an axial tension during their shrinking.
- FIG. 8 illustrates a view in longitudinal section of a possible embodiment of such a heat exchanger with micro-tubes 4 helically wound around a central mandrel 20.
- the bundle of coiled micro-tubes 4 can thus form a tubular entity, the two ends of which can be mounted respectively on the axes of two inserts 21, 22 mounted at the ends of the mandrel 20.
- the peripheral surface (for example cylindrical) of the bundle of microtubes 4 can be coated with a winding or a protective and / or retaining layer 23.
- the fluid 2 circulated in the micro-tubes 4 can be admitted for example transversely to an inlet at one longitudinal end of the exchanger and exit at the other longitudinal end, for example via passages 24 opening through the mandrel 20 and exit via a central passage of an insert 22.
- the cooling fluid can pass it longitudinally around the micro-tubes 4 in a direction opposite to the longitudinal progression of the first fluid 2.
- one and preferably the two longitudinal ends of the bundle of microtubes 4 comprises a layer 13 of rigid material such as a thermosetting (epoxy resin or other) ensuring the cohesion of the bundle of microtubes and resistant to cryogenic temperatures.
- This rigid zone can in particular be used to ensure a seal between the two fluid circuits (for example via one or more seals 18, in particular O-rings interposed between the housing 5 and the resin layer 13 (as illustrated in [ Fig. 3]).
- This mass or layer 13 of solid resinous material bonds the micro-tubes 4 at the ends to prevent the high pressure fluid from communicating with the low pressure fluid when the module is operating.
- the resin used for this part binds reliably with the material constituting the microtubes 4 and also has a high glass transition temperature Tg (for example of the order of 150 ° C.).
- the housing 5 can house at least one elastic member 11 constrained in the longitudinal direction between a stop formed in the housing 5 and a longitudinal end of the bundle of microtubes, to ensure the longitudinal retention of the bundle of microtubes while by allowing its expansion or contraction relative to the housing 5 in the longitudinal direction.
- a longitudinal end of the bundle of microtubes can be blocked longitudinally while the other can be free longitudinally and held by the elastic member 11. This makes it possible to absorb contractions / expansion of the bundle of microtubes when the bundle is subjected to variations in temperature while maintaining the seal.
- the elastic member may comprise or be constituted by a spring 11, in particular helical.
- a spring 11 in particular helical.
- one or more stacked elastic washers 12, in particular of the Belleville type, can be envisaged as shown schematically in [FIG. 5].
- the first fluid 2 (gas or liquid for example at high pressure between 5 bars and 100 bars) can enter via the inlet 6 (on the left in [Fig. 1]), enter the micro-tubes 4 and exit at the other end via the outlet 7.
- the second fluid 3 (gas or liquid for example at low pressure between 1 bar and 99 bar) enters the housing 5 via an inlet (in the upper part of [Fig. 1]). ), circulates around the microtubes 4 and exits via the outlet 9 (in the lower part in [Fig. 1]).
- the housing 5 can be made of a composite material, of epoxy resin with glass fibers, polymer, metal or any other suitable material and in particular the same material as that constituting the micro-tubes 4. This minimizes the contraction differentials between the housing 5. and microtubes 4.
- the pressure differential between the pressure of the fluid circulating in the micro-tubes 4 (for example at high pressure) and the pressure of the fluid circulating around the micro-tubes (for example at low pressure) can be of the order of a few bars or several tens of bar, for example of the order of one hundred bar.
- the housing 5 may include an elastic zone 14 in the longitudinal direction such as a bellows to absorb variations in dimensions due to changes in temperature.
- Such a cryogenic heat exchanger 11 is particularly efficient, compact and lightweight compared to known cryogenic exchangers.
- Such an exchanger can be used in particular as a cooling exchanger in a refrigeration and / or liquefaction device.
- the heat exchanger 1 can in particular be used in a liquefier cooler of the “Turbo Brayton” type.
- FIG. 7 illustrates an example of a cooling device 10.
- This comprises a working circuit 15 containing a working fluid (helium and / or hydrogen and / or argon and / or nitrogen and / or any other gas).
- a working fluid helium and / or hydrogen and / or argon and / or nitrogen and / or any other gas.
- the working circuit 15 comprises at least one working gas compressor 16, at least one heat exchanger 1 for cooling the compressed fluid, at least one member 17 for expanding the working fluid, at least one reheating heat exchanger 117 relaxed working fluid.
- the expansion device may for example comprise at least one from among a turbine, a Joule-Thomson valve, at least one orifice, etc.
- the at least one cooling heat exchanger 1 and / or the at least one reheating heat exchanger 1 can be a heat exchanger 1 of the aforementioned type with polymer microtubes.
- such a heat exchanger 1 can be used in such a device as a countercurrent heat exchanger to heat exchange the working fluid in two distinct states of the cycle.
- heat exchanger 1 For example, at one end of heat exchanger 1 (on the right in [Fig. 7]) the temperature of the fluid is reduced in heat exchanger 1 (for example from non-cryogenic ambient temperature to a cryogenic temperature in particular between 130K and 4K) while at another end (on the left in [Fig. 7]) a flow of this fluid is heated (for example from a cryogenic temperature to a non-cryogenic temperature).
- the heat exchanger 1 is not limited to the above examples. So, for example, the heat exchange can be configured to perform heat exchange between more than two fluids (three, four or more). That is to say that distinct portions of the microtubes 4 and / or of the volume around the microtubes 4 can accommodate distinct flows of fluids (different fluids or fluid of the same nature but at different or similar temperatures) for heat exchange in the heat exchanger 1.
- Such a heat exchanger 1 can if necessary ensure heat exchange with another fluid (liquid nitrogen for example).
- Such a heat exchanger 1 can in particular be used to pre-cool the fluid with a cold heat transfer fluid (liquid nitrogen, or any other fluid).
- a cold heat transfer fluid liquid nitrogen, or any other fluid
- Such a heat exchanger 1 can also be used for cooling the working fluid at the outlet of a compressor.
- the working fluid can be put into heat exchange with a heat transfer fluid such as water for example.
- the fluids put into heat exchange are not necessarily at cryogenic temperatures and could be replaced by a more conventional heat exchanger, but the interest of the aforementioned heat exchanger 1 remains important.
- Such a heat exchanger 1 can also be used to heat a cryogenic fluid contained in a storage.
- the heat exchanger 1 is for example located outside the storage and provides heat exchange between the cryogenic fluid taken from the storage and a hotter fluid (air, water or other heat transfer fluid) to vaporize it.
- such a heat exchanger 1 can be used to cool and / or heat nitrogen, helium, hydrogen, argon or a mixture of all or part of these components. in cryogenic form by heat exchange with a cryogenic fluid or not: nitrogen, helium, hydrogen, argon or a mixture of all or part of the latter and / or water.
