Definitions

  • the present invention relates to heat exchangers.
  • the present invention provides a heat exchanger comprising a static mixer device element having a heat exchange surface in thermal connection with a temperature control means.
  • temperature control means may be used.
  • this may comprise a conduit means for the passage of a heat exchange fluid through the interior of the static mixer device.
  • a solid state heat energy supply and/or drain device could be embedded in the static mixer device.
  • static mixer devices are known in the art.
  • these comprise a static mixer device element longitudinally extending inside a sheath and having a series of wall means which, together with the sheath, repeatedly divide and remix the fluid flow through the static mixer device, as disclosed in, for example our earlier patent GB 2200020.
  • Fluids may comprise: liquids, gases, and mixtures thereof, any of which may also contain suspended particulates.
  • Such fluids may be organic and/or inorganic e.g. water, biological fluids such as blood or plasma, food products such as mayonnaise, ice-cream etc. and industrial products such as paints, chemicals etc.
  • the present invention provides a heat exchanger unit comprising a heat exchanger of the invention longitudinally extending inside a sheath between an inlet and an outlet thereof.
  • the present invention provides a heat exchanger unit of the invention provided with a temperature detector for monitoring the temperature of fluid passing therethrough in use of the invention, a thermal energy supply and/or drain device, and a control means formed and arranged for adjusting the thermal energy supply/drain of said device in response to fluid temperature deviations from a desired value detected by said detector.
  • the thermal energy supply/drain device would normally include pump means for circulating the heat exchange fluid, and a remote thermal energy supply/drain device for adjusting the temperature of the heat exchange fluid passing through the heat exchanger.
  • a preferred form of heat exchanger has a series of helical wall segments extending along the outside of a central tubular core through which the heat exchange fluid circulates. Successive wall segments are angularly offset so that one flow exiting from between one set is divided into separate flows, with successive segments preferably winding in an opposed sense (clockwise - anticlockwise - clockwise etc.) to increase mixing.
  • the heat exchanger may be made of various materials but preferably is of a substantially inert metal with high thermal conductivity e.g. stainless steel.
  • Fig. 1 is a partly schematic partly sectioned view of a heat exchanger device of the present invention.
  • Fig. 1 shows an apparatus 1 comprising a vessel 2 in the form of a cylindrical tube 3 with an inlet 4 and outlet 5, with an axially extending static mixer device 6 provided with temperature control means 7.
  • the static mixer device 6 comprises an axially extending series of angularly offset helical "screw" elements 8 defining pairs of flow paths which are divided equally and mixed at the junctions 9 between successive elements 8 thereby providing a degree of mixing which increases exponentially with the number of elements used.
  • the "screw" elements 8 are mounted on a hollow core 10 which defines a heat exchange fluid passage 11 forming part of the temperature control means 7.
  • the temperature control means 7 comprises a heat exchange fluid circuit 12 provided with pump means 13 for circulating the heat exchange fluid 12a therethrough and a remote Peltier-effect heat exchange device 14 provided with a control means 15 which has a temperature sensor 16 mounted inside the vessel 3 for monitoring the temperature of the fluid 17 undergoing irradiation.
  • the control means 15 is formed and arranged for controlling the rate of cooling supplied so as to maintain a desired fluid temperature. This may be a fixed value, or more conveniently the control means 15 may be provided with user operable input means for varying the desired temperature setting.
  • the core 10 (and desirably also the screw elements 8) are of an inert physiologically acceptable thermally conductive material such as stainless steel in order to facilitate efficient thermal transfer between the fluid being treated 17 and the heat exchange circuit 7 thereby to control the fluid temperature closely within relatively narrow limits so as to on the one hand maximise the efficiency of the sterilisation/inactivation treatment and on the other hand to minimise any undesired denaturation or degradation of useful fluid components.

Abstract

La présente invention concerne un échangeur de chaleur (1) et, en particulier, un échangeur de chaleur constitué d'un mélangeur statique (6) présentant une surface d'échange de chaleur (8) en liaison thermique avec un régulateur de température (7). Une régulation très efficace de la température de fluides (17) peut être obtenue avec l'échangeur de chaleur. Celui-ci effectue un mélange homogène du flux de fluide, grâce auquel le fluide (17) en contact avec la surface d'échange de chaleur (8) est constamment remplacé par d'autres portions du flux de fluide de façon à mettre en contact différentes parties du fluide avec la surface d'échange de chaleur et jusqu'à ce que pratiquement la totalité du flux de fluide soit exposée à l'échangeur de chaleur (1). On obtient ainsi une régulation particulièrement précise et uniforme de la température du flux de fluide. Des fluides dont on peut réguler la température au moyen de l'échangeur de chaleur inventé peuvent être des fluides organiques et/ou des fluides inorganiques comme, par exemple, l'eau, les fluides biologiques (sang, plasma), les produits alimentaires (mayonnaise, crème glacée) ou les produits industriels (peintures, produits chimiques).
