Definitions

  • the present invention relates to a sorption heat transfer module.
  • Thermally driven sorption refrigeration systems have a high energy saving potential since inexpensive waste and excess heat is as used as drive energy and as a result, the pressure on the electrical networks can be reduced, particularly in hot time and climate zones with a high refrigeration requirement.
  • These installations can also be used as heat pumps which by means of burner heat raise additional environmental heat to a temperature level sufficient for heating purposes, with the result that the fuel requirement can be reduced.
  • German Patent Application DE 10 2011 079 586 A1 describes such a sorption module whose housing design is however still very complex and is a source of some loss mechanisms.
  • a disadvantage is the complex design with a fairly large number of joints to be sealed hermetically.
  • a disadvantage of the proposed cylindrical module concept is the quality of the thermal connection of the phase change structures to a fluid heat transfer medium and the comparatively large thermal mass, which has a harmful effect on the power density and the efficiency of the sorption module. Furthermore, there is the problem that depending on the installation position of the cylinder module, it can occur that condensate bound in the capillary structure can be displaced in the entire structure due to gravitational and acceleration effects. For example, condensed working medium can accumulate in low-lying regions, with the result that conversely high-lying regions of the capillary structure dry out too rapidly during the evaporation phase.
  • Another weak point of the said embodiment of the housing jacket carrying this capillary structure is the difficulty of applying the internal capillary structure with very good thermal contact.
  • a metal firmly bonded connection preferably by soldering should be strived for, which is made difficult by the protective oxide layer of stainless steel.
  • a third weak point of the last-mentioned module design is the heat transfer coefficient k on the side of the heat transfer agent, which serves to remove or supply the condensation heat and the heat of evaporation with the smallest possible driving temperature difference.
  • the present invention is concerned with the problem of providing an improved cylindrical sorption module with thermally activatable housing. This problem is solved according to the invention by the subject matter of the independent claim(s). Advantageous embodiments are the subject matter of the dependent claim(s).
  • the present invention is based on the general idea that a housing with suitable structures simultaneously provides a heat transfer surface in order to transfer condensation heat and/or evaporation heat with very good heat transfer to a or from a fluid heat transfer medium.
  • a substantial contribution can thus be made to increasing the volumetric power density, the efficiency and also to reducing the manufacturing costs.
  • the first two optimization criteria in this case require a structure combination by means of which a total heat transfer coefficient from the heat transfer medium to the phase change structure and from there to the saturation temperature of the working medium vapour of overall 1500 W/m 2 *K is exceeded.
  • the individual thermal resistances of the heat transfer path must therefore be minimized under the boundary condition of minimal production costs for material and joining processes.
  • a sorption heat transfer module having a thermally activatable housing which encloses a sorption zone through which a working medium can flow
  • the housing according to the invention comprises a gastight inner wall made of a corrosion-protected material, the internal surface of which is adjoined by a capillary structure which consists of at least one corrugated fin package which is connected in a firmly bonded manner to the internal surface of the inner wall.
  • the thermally activatable housing comprises an outer wall which encloses the gas-tight inner wall and together with the inner wall forms an annular channel for a heat transfer agent through which axial flow can take place. Via this annular channel, a heat transfer agent can flow particularly simply and specifically through the sorption heat transfer module according to the invention and the condensation heat can be efficiently removed.
  • a particularly compact design can be achieved if the inner wall and the outer wall are each configured cylindrically, if the inner wall is arranged coaxially and concentrically in the outer wall and if the annular channel is arranged radially between inner wall and outer wall.
  • This compact design can be assisted by the fact that the annular channel has smaller dimensions in the radial direction than the capillary structure.
  • the annular channel has respectively one inlet-side and/or outlet-side annular beading.
  • the inlet-side annular beading can serve as a distribution box whilst the outlet-side annular beading can serve as a collecting box.
  • the solution according to the invention consists in particular in using corrosion-protected steel such as, for example, stainless steel, zinc-plated, nickel-plated or particularly preferably tin-plated steel (tin sheet) as material for a gas-tight housing wall.
  • corrosion-protected steel such as, for example, stainless steel, zinc-plated, nickel-plated or particularly preferably tin-plated steel (tin sheet) as material for a gas-tight housing wall.
  • tin sheet tin sheet
  • tin sheet tin sheet
  • the capillary structure is preferably made of optionally tin-plated copper strip as phase change structure for condensation, capillary binding of condensed working medium, preferably methanol and re-evaporation of the condensate, wherein closed corrugated fin annular packages are provided for soldering to the inner wall of the corrosion-protected housing.
  • the application of the corrugated fin packages is provided here in such a manner that the tips of these corrugated fin packages are soldered to an internal surface of the inner wall.
  • the application of the corrugated fin packages is additionally provided in such a manner that the front faces of the corrugated fin packages are soldered to the internal surface of the inner wall.
  • a soft-soldered assembly can be created consisting of a gas-tight cylinder with internally soldered-on capillary structures and externally soldered-on corrugated fins and in a second step this assembly can be completed by an outer wall which with the gas-tight inner wall forms an annular channel through which axial flow can take place so that the inner assembly can be thermally activated by flow with a heat transfer agent.
  • corrugated fins and fin packages made from these are understood as continuously rollable zig-zag structures made of thin-walled metal strip which can be formed very differently in detail, for example with or without gills.
  • a heat-conducting structure adjoins an external surface of the gas-tight inner wall, which is connected in a firmly bonded manner to the inner wall and which preferably consists of at least one corrugated fin package.
  • This heat-conducting structure appreciably increases the efficiency of the sorption heat transfer module and can be produced in a modular manner similar to the capillary structure.
  • a thermally insulating layer preferably a silicone foam mat, is inserted between the heat-conducting structure and the outer wall in order to ensure thermal insulation of the annular channel towards the outside and to minimize the connected thermal mass.
  • a silicone foam mat is specifically available as prefabricated material in different dimensions and is particularly easy to process.
  • the annular channel has respectively one inlet-side and/or outlet-side annular beading which is used for a homogeneous distribution of the axially directed volume flow of a heat transfer agent in the circumferential direction.
  • the heat-conducting structure is arranged here in the aforesaid annular channel.
  • the heat can be efficiently transferred between the fluidic heat transfer agent flowing in the annular channel and the inner wall.
  • the heat-conducting structure extends in an annular manner in the annular channel.
  • the heat-conducting structure extends starting from the inner wall in the annular channel over at least 80%, preferably over at least 90% of a radial channel width of the annular channel. This also improves the utilization of the space present in the annular channel.
  • the efficiency of the heat transfer between the heat transfer agent and the inner wall can also be improved whereby a thermally insulating layer, preferably a silicone foam mat, is arranged in the annular channel radially between the heat-conducting structure and the outer wall. This reduces any heat transfer between the heat-conducting structure and the outer wall or between heat transfer agent and outer wall.
  • a thermally insulating layer preferably a silicone foam mat
  • the compact design can also be assisted if according to one embodiment, the heat-conducting structure has smaller dimensions in the radial direction than the capillary structure.
  • tips or front faces of individual corrugated fin packages of the capillary structure and/or heat-conducting structure are connected in a firmly bonded manner to the inner wall and are preferably located opposite the corrugated fin packages of the capillary structure and the heat-conducting structure so that they overlap.
  • the firmly bonded connection of tips or front faces and preferred opposite position of the two structures ensures a particularly good thermal contact via the inner wall.
  • the corrugated fin packages of the capillary structure which are connected in a firmly bonded manner on the front side have through-openings in a rolling plane, which allow an axial passage of the working medium between the inner wall and the corrugated fin packages arranged thereon.
  • at least two of the through openings are arranged between two axially adjacent corrugated fin packages of the capillary structure offset with respect to one another in the circumferential direction in order to enable a flushing transport of undesirable non-condensable external gases in the principal flow direction.
  • At least two of the axially adjacent corrugated fin packages connected in a firmly bonded manner on the front side are arranged offset with respect to one another in the circumferential direction.
  • the corrugated fin packages of the capillary structure connected in a firmly bonded manner on the front side can also be arranged axially parallel and spaced apart from one another in the circumferential direction, preferably arranged spaced apart from one another in a contact-free manner, so that wedge-shaped axial flow channels are formed between the individual corrugated fin packages.

With the choice of these dimensions, in practice a particularly high efficiency of the sorption heat transfer module can be demonstrated.
  • the gas-tight inner wall is made of a corrosion-protected steel material, in particular a zinc-plated, nickel-plated or tin-plated steel, and/or the capillary structure and/or the heat-conducting structure is made of a copper material, in particular a tin-plated copper strip, which is preferably soft soldered to the gas-tight inner wall and the working medium is an alcoholic fluid, in particular methanol or ethanol.
  • the working medium is an alcoholic fluid, in particular methanol or ethanol.

  • the optionally tin-plated semi-finished product materials such as for example tin plate for the gas-tight inner wall and optionally tin-plated copper strip for fabricating the phase change structure in the form of corrugated fin packages having a high fin density and thus attainable capillary condensate retaining function and the surface-enlarging fin system of the annular channel for fluidic flow enable a very cost-effective and thermally very good conducting joining process of the three required structure components.

  • the fin orientation of this embodiment avoids flow-off effects of stored condensate since no passage paths are provided due to a smooth gill-less fin design.
  • This fin orientation is therefore suitable both for horizontal and for vertical module installation.
  • This particularly preferred second embodiment additionally has the advantage of easier applicability of the individual corrugated fin packages and axially assisted vapour flow with external gas flushing effect.
  • the axial flow through the housing 2 . . . 2 ′′′ is however not necessarily advantageous.
  • the material combination based on steel materials is due to the favoured alcohol working media (methanol, ethanol).
