Definitions

  • the present invention concerns a cooling plate, a cooling device, a use of a cooling plate, and a method for manufacturing a cooling plate.
  • Cooling plates are used in cooling devices, for example for cooling and freezing liquids occurring in or resulting from a bio-pharmaceutical production process.
  • the resulting frozen liquid which represents a sizeable monetary value, can afterwards be transported or stored in such a way that the frozen liquid is protected from damage, stemming for example from mechanical impacts, and potentially resulting loss of sterile integrity.
  • cooling plates for cooling liquids or other goods with a liquid content are also known from other areas, for example from the food industry.
  • cooling plates include at least one cooling channel for a cooling medium which is disposed inside a plate body.
  • the liquid to be cooled is placed adjacent to a cooling plate or between cooling plates, and a cooling medium of lower temperature than the liquid is pumped through the at least one cooling channel. Heat from the liquid is then conducted into the cooling medium, thereby cooling the liquid.
  • a cooling device making use of cooling plates for use in the bio-pharmaceutical production process is known from unpublished European Patent Application no. 20181117.1 or from WO 2020/047571 A1 .
  • Containers for liquids occurring in or resulting from a bio-pharmaceutical production process and which are adapted for freezing in a cooling device are known from WO 2018/129576 A1 .
  • Cooling plates according to the prior art are for example manufactured by providing two steel sheets which are connected at their periphery by distance panels, e.g. by welding, such that a plate-like shape results.
  • the cooling channel is realised by further panels which are welded into the inside in such a way as to create a meandering channel.
  • a further problem is deformation of the surface of the cooling plate because it is difficult to weld the different panels with high enough accuracy such that the surfaces of the cooling plate are plane enough.
  • a surface of the cooling plate which is as plane as possible is of course desired, because the larger the contact area between the cooling plate and the container of the liquid to be cooled is the better the heat transfer between the container and the cooling plate will be. Therefore, a cooling plate with precise geometrical shape directly contributes to an effective cooling.
  • the object of the invention is therefore to provide a cooling plate and a method for manufacturing a cooling plate, wherein the properties regarding liquid tightness for the cooling medium, corrosion, and/or precise geometrical shape are improved compared to the prior art.
  • a cooling plate with a plate body and at least one cooling channel which is disposed inside the plate body and which is at least partly delimited by the plate body, wherein the plate body comprises
  • the object is achieved by a method according to claim 12, the method comprising the following steps:
  • the invention provides a cooling plate and a method for manufacturing the same from significantly fewer component parts than in the prior art. Furthermore, the at least one cooling channel is easily delimited (at least in part) by two parts which are made up of full or mainly full material (i.e. reduced or no hollowness), such that potential leaks and corrosion automatically become much less likely.
  • first part and the second part from full material blanks allows for much better geometrical precision of the cooling plate compared to a welded construction made up of sheet metal.
  • the first component part can realise a first plane (i.e. flat) surface of the plate body and/or the second component part can realise a second plane (i.e. flat) surface of the plate body.
  • first plane i.e. flat
  • second plane i.e. flat
  • the first component part and the second component part can preferably interface along a surface which is substantially parallel to the first plane surface and/or the second plane surface.
  • the plate body is preferably of a plate-like base shape, preferably with a rectangular base area.
  • the cooling plate could also have a different base shape, for example as a curved or bent plate-like shape.
  • the at least one first recess and the at least one second recess can each be divided into separate recesses, which are themselves contiguous, resulting in more than one cooling channel which are at least in part delimited by the separate first and second recesses.
  • the at least one first recess and/or the at least one second recess can each be a single contiguous recess.
  • the at least one cooling channel can be of circular cross-section. However, in particularly preferred embodiments the at least one cooling channel are somewhat flattened with flat inner surfaces parallel to the first plane surface and/or the second plane surface of the cooling plate.
  • the at least one cooling channel can lead through the plate body in a meandering manner of fashion in order to cover as much of the area of the cooling plate and in order to achieve a heat transfer which is as homogeneous over the area of the cooling plate.
  • the first component part and the second component part are attached to each other such that the at least one first recess and the at least one second recess face each other and such that the at least one first recess and the at least one second recess together realise at least part of the at least one cooling channel inside the plate body.
  • one side of the cross section is given by the at least one first recess and the other side of the cross section is given by the at least one second recess.
  • the at least one first recess and the at least one second recess are arranged on top of each other such that material around the recesses together delimits the at least one cooling channel.
  • first blank body and the second blank body which are furnished with the first recess and the second recess can be made of full material blank bodies.
  • the first component part, the second component part, the first blank body, and/or the second blank body can preferably be made of stainless steel.
  • the at least one first recess and/or the at least one second recess can preferably be formed into the first blank body and/or the second blank body, respectively, by a cutting method in the engineering sense, in particular milling.
  • first recess and the second recess correspond to each other geometrically does not necessarily mean that they have to be of equal geometrical shape. That the first recess and the second recess correspond to each other geometrically can interpreted in the sense that they are able to together delimit the at least one cooling channel in a state where the first component part and the second component part are attached to each other.
  • Protected is also a cooling device comprising at least one cooling plate according to the invention.
  • the cooling plate according to the invention or the cooling device according to the invention can both be used for cooling, in particular freezing, and for heating, in particular thawing, liquids or goods containing a liquid component.
  • the cooling or heating is achieved by arranging the liquids or goods to be cooled or heated adjacent to the cooling plate according to the invention or between cooling plates according to the invention, and supplying a cooling or heating medium of higher or lower temperature than the liquids or goods, respectively, to the cooling plate(s).
  • Protected is furthermore a use of a cooling plate according to the invention or a cooling device according to the invention in cooling, in particular freezing, and/or heating, in particular thawing, a liquid occurring in and/or resulting from a pharmaceutical production process, in particular a bio-pharmaceutical production process.
  • a cooling plate according to the invention can be particularly advantageous as leaks, corrosion, as well as inhomogeneous or ineffective heat transfer can have a quite detrimental effect due to the valuable nature of the liquids to be frozen or thawed.
  • the first component part and the second component part can be attached to each other with at least one mechanical connection and/or at least one adhesive bond.
  • the at least one mechanical connection can be embodied as at least one thread and screw connection and/or at least one positive lock connection.
  • a screw head of the at least one thread and screw connection is welded substantially flat, and a remaining substantially flat surface is polished and/or sanded.
  • the screw head of a thread and screw connection can disturb the surfaces of the cooling plate, which as already mentioned contributes to an efficient heat transfer.
  • welding the screw head flat e.g. by removing part of the screw head and/or filling a central recess of the screw head, can therefore be beneficial for a substantially flat or (first or second) plane surface of the cooling plate. This can be further improved by sanding and/or polishing the remaining surface.
  • first and/or second plane surface can also be polished and/or sanded independently of the presence of a thread and screw connection.
  • Positive lock connections are connections which fasten two component parts, here the first component part and the second component part, to each other by way of the shape of the objects or geometrical features realising the connection (in contrast to a frictional connection or a force closure).
  • the at least one positive lock connection can comprise a hook component part (preferably more than one hook component part) which is separate from the first component part and/or the second component part, wherein the hook component part includes a first hook element and/or a second hook element, and wherein the first hook element is engaged with a first undercut in the first component part and/or the second hook element is engaged with a second undercut in the second component part.
  • a hook component part preferably more than one hook component part
  • hook component part and "hook elements” here are not be understood narrowly so as to have to have a shape of a commonly known hook.
  • hooks should merely be understood as geometrical features which cooperate with an undercut or the like in order to achieve a positive lock.
  • the hook component part and/or the first hook element and/or the second hook element can for example be embodied as a T-shaped sliding element cooperating with an undercut (in particular if viewed in a cross section).
  • the hook component part can be embodied as double T-shaped sliding elements (T-shapes on opposing sides).
  • the hook component part and/or the first hook element and/or the second hook element could also incorporate a conical shape instead of a (double) T-shape (in particular if viewed in a cross section).
  • the hook component part can preferably be arranged on an inside of the plate body, i.e. not on the periphery of the plate body.
  • the method according to the invention further comprises attaching the first component part and the second component part to each other using a positive lock connection, preferably additionally comprising
  • Such embodiments can preferably additionally comprise engaging the first hook element with the undercut in the first component part, bringing the second component part into contact with the first component part, and moving the second component part relative to the first component part laterally along an interface between the first component part and the second component part until the second hook element of the hook component part engages with the second undercut of the second component part, or vice versa.
  • a force closure can additionally be present when the second component part is moved laterally along the interface with the first component part (or vice versa). Then the first and second component parts are secured on the one hand against unwanted relative lateral movements by the force closure, and potentially another mechanical connection and/or adhesive bond, and are secured on the other hand against unwanted relative axial movements (i.e. parallel to a normal direction on the surface of the cooling plate) by the positive lock connection, and potentially another mechanical connection and/or adhesive bond.
  • the at least one adhesive bond can for example be a metallic continuity bond, in particular a welded bond.
  • Other adhesive bonds, for example with an adhesive substance (glue) are of course in principle conceivable.
  • the first component part and the second component part can be bonded to each other through the adhesive bond along at least one peripheral side, preferably all peripheral sides, of the first component part and the second component part.
  • first component part and the second component part are attached to each other by at least one positive lock connection, preferably with at least one hook component part as described before, and an adhesive bond, in particular a weld, wherein there is preferably no thread and screw connection.
  • the at least one positive lock connection can be arranged in a central portion of the cooling plate and the adhesive bond is arranged around the peripheral sides of the cooling plate.
  • the adhesive bond is arranged around the peripheral sides of the cooling plate.
  • the cooling plates can have side lengths between 500mm and 1500mm, preferably between 700mm and 1200mm, and particularly preferably between 800mm and 1100mm.
  • FIG. 1 shows an exemplary embodiment of a cooling plate 1 according to the invention.
  • a plate body 2 of the cooling plate 1 comprises an internal cooling channel 3 (see Figures 3a, 3b and 6 ).
  • Ports 19 can be used to connect tubing or piping for conveying a cooling medium through the at least one cooling channel 3.

  • the blank bodies can for example be made of stainless steel.
  • the blank bodies could be made of Aluminium or (other) materials which offer high heat transfer, resistance to corrosion and impermeability for a cooling or heating medium.
  • the first blank body 17 and/or the second blank body 18 can be of substantially cuboidal base shape.
  • the blank bodies are of substantially plate-like base shape, i.e. a height of the blank bodies may be much smaller than a width and a length of the blank bodies.
  • the width and length are different from each other.
  • embodiments with equal lengths and widths are in principle conceivable. Since the first blank body 17 and the second plate body 18 eventually make up the plate body 2, analogous statements are true for the plate body 2.
  • At least one first recess 5 is formed in the first blank body 17 and at least one recess 7 is formed in the second blank body 18 ( Fig. 3a and 3b ), such that the first recess 5 and the second recess 7 correspond to each other geometrically.
  • first blank body 17 becomes the first component part 4
  • the second blank body 18 becomes the second component part 6.
  • first recess 5 and the second recess 7 are depicted as geometrically substantially equal in Fig. 3a and 3b .
  • first recess 5 and the second recess 7 can be of different geometrical shape while still able to together delimit the at least one cooling channel 3 in a state where the first component part 4 and the second component part 6 are attached to each other, as laid out previously.
  • openings 20 can be formed into the first blank body 17 and/or the second blank body 18, which later allow attachment of the first component part 4 and the second component part 6 to each other.
