Definitions

  • ABSTRACT A method of manufacturing a heat exchanger for exchanging heat between helium flows in a temperature range below 2K, comprising two end plates having inlet and outlet apertures, and a stack of very thin foils arranged between the end platesvwith passageways that extend transverse to the planes of the foils and separate ducts in the planes of the foils which communicate with the passageways.
  • the foils are attached with supports provided between foils, which supports are removed by means of a rinsing liquid after the foils have been soldered to each other.
  • the heat exchanger relating to the method according to the present invention is intended for exchanging heat between two helium. flows at temperatures below 2K.
  • the method according to the invention has for its obproportions and its construction is very 2 stack of foils and the assembly is subjected to a thermal treatment during which the foils are connected to each other by soldering or diffusion. Then the heat exchanger thus formed is rinsed with the said rinsing liq uid and the supports are removed.
  • a heat exchanger manufactured by the method according to the invention use is'made of foils which have a very small thickness but which are nevertheless vacuum tight. With the very small thickness dimension of the separating wall (2-1011), the phonons can now readily penetrate through this separating wall as a result of two effects, i.e., the phonon tunnel effect and the free-path length effect. Thanks to these. effects a striking improvement" of the exchanging of heat is achieved. Furthermore, the heat exchanger thus obtained has a small volume and a low flow resistance.
  • a difficulty encountered in the manufacture is the vacuum-tight connection of the foils.
  • This connection can be obtained by soldering, in which case the foils i must be provided with a layer of solder, or by diffusion.
  • the method is characterized in that the stack of plates is formed by a number of very thin metal foils which are proportioned such that the thickness of the separating walls between the ducts is 2-10 u, .the thickness dimension of the ducts being between 401.0 and 100p.
  • a support having the same thickness dimension as the parallel ducts is provid'ed during the stacking of the foils, at least at the area where each of the parallel ducts communicates with a through duct, this support being made of a metal which can be selectively removed ata later stage by means of a rinsing liquid which does not attack thefoils.
  • This problem is eliminated in theinvention by'providing a support, in at least these areas, which ensures theltransfer of force.
  • This support is made of ametal which can be etched away-at a-later stage by means of a rinsing liquid, without the foils being attacked. In this manner very good adhesion of the foils is achieved.
  • each of the supports to be provided is formed by a frame which can consist of a number of parts and which extends along the entire inner edge of the relevant parallel duct.
  • each of the foils is formed by growing a layer having a thickness of less than 5 ron a suitable substrate in an electrochemical manner.
  • FIG. 1 is an exposed view of a heat exchanger.
  • FIG. 2 shows the heat exchanger of FIG. 1' in the operating condition.
  • FIGS. 3 and 4 show how supports can be used for sembly.
  • FIGS. 5 and 6 diagrammatically illustrate how a foil can be made.
  • FIGVI diagrammatically shows the construction of a heat exchanger. It comprises two end pieces 1 and 2, each of which is provided with an inlet aperture, 3 and 4, respectively, for a helium flow forward and rearward and with an outlet aperture, 5 and 6, respectively.
  • a stack 7 of copper foils Arranged betweenthe end plates 1 and 2 is a stack 7 of copper foils. These foils are divided into closed foils 8 having a thickness of approximately 2 t, and foils 9 having a rectangular aperture.
  • apertures 1.0, 11, 12 and 13 four through ducts or passageways are obtained which communicate with the apertures 3, 4, 5 and 6, respectively, in the end plates defining forward flow via inlet aperture 3, passageways 10 and 13,
  • Two methods can be used to obtain adhesion of the end plates to the foils, i.e., soldering and diffusion.
  • supports 20 can be provided at the areas 18 as shown in FIG. 3 in the case of diffusion of the foils. It is thus achieved that the foils are properly pressed together also at the areas 16. During the relevant thermal treatment, the foils will be properly diffused together also at these areas.
  • the supports in the form of a frame 22, as shown in FIG. 4, which extends along the entire inner edge of the relevant parallel duct.
  • This frame offers the important advantage that the flowing of soldering material into the duct space is completely counteracted, so that these ducts cannot become clogged. So as to ensure proper transfer of forces at the areas 18, the frame 22 has such a thickened portion 23 at these areas that only a narrow gap remains.
  • the supports as well as the supporting frames are made, for example, of soft steel or aluminium, respective'ly, i.e., materials which can be removed by means of an acid or a lye after completion of diffusion or soldering, respectively. To this end, it is important that the acid or the lye can be rinsed through, so the supports and supporting frames may not completely block the passage.
  • FIG. 2 After completion of these operations, a heat exchanger as shown in FIG. 2 is obtained.
  • This heat exchanger excels by its favourable heat exchanging properties, small volume'and low flow resistance. Furthermore, the use of the method according to the invention ensures a very reliable and leak-free heat exchanger.
  • foils two kinds are used, i.e., closed foils having a thickness of approximately 2 ,u and foils having an aperture and a thickness of approximately 40 [1... It was found that foils can be manufactured in which these two are combined. The manufacture thereof is diagrammatically shown in FIGS. 5 and 6.
  • a brass plate 30 On a brass plate 30 layers of lacquer are first pro-- vided at the areas 31, 32, 33 and 34. Subsequently, a copper layer 35 is electrochemically grown to a thickness of approximately 2 M. After'that, a lacquer layer 36 is provided ant the copper foil is grown further to approximately 40 .t.
  • a method of manufacturing a heat exchanger through which fluid can flow in forward'and rearward directions comprising the steps of'stack'ing alternately thin'metal sheets of thickness in the range of 2- 1 0p. and thick metal sheets of thickness in the range 40lO0;/., said thick sheets having apertures therein which with said adjacent thin sheets define ducts extending generally parallel to the planes of said sheets with height of the ducts equal to the thickness of said thicksheets, said ducts being forward flow ducts spaced alternately, and rearward flow ducts situated intermediate each two forward-flow ducts, said thick and thin sheets having further apertures that are aligned along axes transverse to said planes of the sheets to'define at least two separate passageways for said forward and rearward flows respectively, said forward flow passageway and duct being in communication, and said rearward flow passageway and duct being in communication, placing in each of said ducts and between and contacting the adjacent thin sheets a support having thickness substantially the same as that of said thick sheet, each support being
