Definitions

  • the present invention relates to the cooling of radiation shields in vessels and apparatus containing low-boiling liquids as coolants, and particularly to the cooling of radiation shields by establishing a heat-conducting connection with portions of the waste gas line of such apparatus.
  • Storage vessels for liquid helium are known in which a vacuum-insulated inner container is enclosed by a plurality of protective shields.
  • the shields are supported by the neck tube of the container and are cooled via their metallic connection with this tube; such cooling being eifected by utilizing the heat absorbing capacity of the evaporated gas.
  • Another object of the invention is to substantially improve the efficiency of the cooling action effected by the waste gas.
  • Still another object of the invention is to provide a more efiicient heat exchange between the associated radiation shields and the waste gas.
  • Still another object of the invention is to provide an improved heat exchange without increasing the flow resistance of the waste gas line.
  • This apparatus includes a container for such liquid, a waste gas pipe connected to the container and communicating with the interior thereof, and a radiation shield surrounding the container and connected to the pipe in a heat conductive manner for permitting at least part of the shield to be cooled.
  • the heat exchange element according to the invention is connected in series in the pipe to be traversed by the gas flowing through the pipe, the element presenting a gas flow path whose cross-sectional area is greater than that of the gas flow path defined by the pipe and having an outer surface contacting the shield and defining the surface via which heat is transferred from the shield.
  • the present invention provides a device for cooling radiation shields in which favorable heat transfer conditions are created and which can be manufactured, installed and disassembled in a simple manner. Moreover, heat exchange elements according to the invention do not create any noticeable increase in the gas flow resistance of the waste gas pipe.
  • Heat exchange elements according to the invention are highly advantageous because, even when the waste gas pipe is relatively short, these elements serve to substantially enlarge the effective heat exchange area, which results in a corresponding increase in the rate at which heat can be exchanged with the radiation shields.
  • the heat exchanger is constructed so that its gas flow region is provided with gas conduits formed in a heat conductive ma terial and presenting a gas flow region which is symmetrical with respect to the longitudinal axis of the exchanger.
  • the interior of the exchanger has the form of a helical conduit.
  • the unobstmcted cross section of the heat exchanger gas flow region which is in the form of a cylinder defining the inner boundary of the conduit, has a cross-sectional area equal to, and coaxial with, the cross-sectionl area of the interior of the waste gas pipe.
  • the dimensioning of the heat exchanger to cause it to have an unobstructed cross section which is equal to that of the waste gas pipe is advantageous because it assures that standardized siphons can be inserted through both the pipe and the heat exchanger.
  • a further pipe which extends through the heat exchanger and partially through the waste gas pipe, the further pipe having a smaller cross-sectional area than the waste gas pipe so that the two pipes define an annular gas flow path, and being connected to the helical conduit which has an unobstructed cross section of smaller diameter than the cross section of the waste gas pipe.
  • the heat exchange element can be constituted by a sintered metal packing disposed within a hollow jacket and extending across the entire cross-sectional area of the hollow region defined by the jacket, the packing being dimensioned to cause the jacket to also present a gas distribution chamber at each end of the packing. Arrangements of this type are highly advantageous because they permit optimum heat exchange conditions to be achieved.
  • the radiation shields which are to be cooled are formed with a socket-type sleeve into which a heat exchanger according to the invention can be tightly inserted in such a manner as to cause the outer surface of the heat exchanger to be in close heat-exchanging contact with the socket.
  • FIG. 1 is a cross-sectional view of one embodiment of a heat exchanger according to the invention.
  • FIG. 2 is a simplified pictorial illustration of a storage vessel constructed according to the invention.
  • FIG. 3 is a view similar to that of FIG. 1 of another embodiment of the invention.
  • FIG. 4 is a view similar to that of FIG. 1 of still another embodiment of the invention.
  • FIG. 5 is a view similar to that of FIG. 2 of a continuous-flow cryostat constructed according to the invention.
  • the heat exchanger 1 consists of a cylindrical hollow body 2 whose inner wall is formed to create a helical, heat-conductive gas conduit 3 which, it should be noted, does not extend along the entire length of the inner wall, and which defines a gas fiow channel 3.
  • the heat exchanger 1 is made, for example, of copper and is interposed as an intermediate piece in the thin-walled waste gas pipe 4 made of a material having a low thermal conductivity and high structural strength, one such material being refined steel.
  • a radiation shield 6 provided with an integral plugtype sleeve 5 is connected to the outside of the heat exchanger 1 in such a way that the entire external surface of the heat exchanger 1 is in good heat exchange contact with the radiation shield 6.
  • the unobstructed cross section of the heat exchanger 1, which is a cylindrical region defining the inner boundary of channel 3' corresponds with the cross section of the waste gas pipe 4, so that, for example, a siphon, or probe, or the like, can pass through the heat exchanger 1 for insertion into the inner container.
  • a siphon whose diameter is somewhat smaller than the diameter of the waste gas pipe 4 has been inserted, an annular gap results between the siphon jacket pipe and the pipe 4, this ,gap being interrupted by heat exchanger 1, and it is through this gap that the waste gas flows. If no siphon 4 were inserted, the full cross section of the gas pipe 4 would be available for the flow of exhaust gas.
  • FIG. 2 shows a variant of the heat exchanger illustrated in FIG. 1 in association with a storage can 7 having two radiation shields 8 and 9 surrounding an inner vessel 12 containing a coolant 11.
  • the heat exchangers are here of smaller unobstructed cross section than in FIG. 1 and are traversed by an inner pipe 10 which is connected to the inner boundary of the gas conduits 3.
  • the inner pipe 10 extends from below the heat exchanger 1a, which is connected to the innermost shield 9, to the outer end of the gas pipe 4, pipe 4 here constituting the neck tube of inner vessel 12, and is enclosed by the waste gas pipe 4. Between the inner pipe 10 and the gas pipe 4 there is thus created an annular gap which is interrupted by the two heat exchangers 1a and 1b and through which the waste gas flows toward the waste gas discharge connection 13.
  • This embodiment presents the advantage that the waste gas will be fed through a narrow annular gap even when no siphon is present and that the entire mass of waste gas is forced to flow substantially through the helical conduits of the heat exchangers la and 1b.
  • the upper end of inner pipe 10 is closed by a cover or stopper 14.
  • This arrangement is of particular interest when large amounts of waste gas develop, for example in storage vessels having large capacities.
  • FIG. 3 shows another embodiment of the heat exchanger according to the invention which is advantageously employed in those cases where nothing need be inserted through the waste gas pipe.
  • the free cylindrical region enclosed by, and defining the inner boundary of, the helical gas conduit 3 is here closed off by a permanently inserted solid heat-conducting plug 15 which extends over the entire length of the helical conduit.
  • a gas distribution chamber 17 At the gas inlet side of the heat exchanger there is provided a gas distribution chamber 17 within the heat exchanger.
  • a similar chamber 16 is provided at the gas outlet side. This embodiment also serves to cause the entire mass of Waste gas to flow through the heat exchanger helical conduit.
  • FIG. 4 shows an embodiment of the heat exchanger in which a sintered-metal packing 18 is inserted in a closed cylindrical hollow body, made of two parts 2a and 2b, to serve as the heat-exchange element.
  • a sintered-metal packing 18 is inserted in a closed cylindrical hollow body, made of two parts 2a and 2b, to serve as the heat-exchange element.
  • optimum heat exchange-conditions can be realized since, as is known, sintered-metal bodies present a very large internal surface and good thermal conductivity.
  • Appropriate sintered-metal packings could also be used in the embodiment illustrated in FIG. 2.
  • Materials suited for the sintered-metal packing are copper, silver, aluminum, bronze and the like.
  • FIG. 5 is a schematic representation of a continuousflow cryostat in which heat exchangers of the type illustrated in FIG. 4 are used.
  • the radiation shields 22 and 23 are in heat-conductive communication with the heat exchangers 24 and 25, respectively, disposed in series with the waste gas pipe 4 of evaporator 20.
  • the entire apparatus is enclosed in an evacuatable housing 26.
  • the heat exchangers illustrated in FIGS. 3 and 4 are the most advantageous embodiments to he employed in this apparatus.
  • the exhaust gas pipe may be constructed of sections having progressively increasing cross-sectional areas corresponding to the decreasing density of the gas, thus keeping the flow resist ance of the waste gas pipe at a low value.
  • a heat exchange element connected in series in said pipe to be traversed by the gas flowing through said pipe, said element being a hollow body whose cross-sectional area is greater than that of the gas flow path defined by said pipe and having an outer Wall contacting said shield and defining the surface via which heat is transferred from said shield; and gas flow directing means disposed in said hollow body adjacent said outer wall and constructed for deflecting at least that part of the gas flowing adjacent the inner surface of said outer wall to cause such gas to follow a flow path through said element which is longer than the axial length of said element.
  • said directing means comprise at least one heat-conductive gas conduit which defines the gas flow path and wherein said element is symmetrical with respect to its longitudinal axis.
  • An arrangement as defined in claim 2 further comprising an inner pipe passing completely through said heat exchanger and at least partially through said waste gas pipe, the external diameter of said inner pipe being less than the internal diameter of said waste gas pipe and said inner pipe and waste gas pipe defining between them an annular gas flow region, and said inner pipe being connected to the inner boundary surface of said heat exchanger having an unobstructed cross section of less than the internal diameter of said waste gas pipe.
