Description

[Technical field]

[0001] The present invention relates to an apparatus for adjusting the temperature and thawing a temperature-controlled article, comprising a housing having a temperature-controlled article, a heating module for transferring heat to at least one side of the temperature-controlled article, and an actuator capable of moving the temperature-controlled article.

[0002] Furthermore, the present invention relates to a method for adjusting and thawing a temperature-controlled article, wherein a pressure force is partially applied to the temperature-controlled article within a preset time interval by an adjusting element. [Background technology]

[0003] An installation for thawing a temperature-controlled article is known from US 6748164. In the installation, the temperature-controlled article is surrounded by a heating mechanism. A warm liquid is circulated in the heating mechanism. Heat is transferred from the heating mechanism to the temperature-controlled article by direct thermal contact between the heating mechanism and the temperature-controlled article. To accelerate the thawing process, a housing base that can be moved up and down periodically is configured as an adjustment mechanism. The heating mechanism is arranged on the housing base. The heating mechanism is thus transferred to a pivoting movement. In this case, a pivoting axis extends along the periphery of the heating mechanism. The temperature-controlled article is thus pivoted indirectly. In this case, a peripheral surface is arranged close to the pivoting axis.

[0004] An installation for thawing a temperature-controlled article is known from US Pat. No. 8,012,416. In this case, opposite sides of the temperature-controlled article are in contact with a heating mechanism. The lower heating mechanism is arranged on a number of support plates. The support plates are respectively attached to an inflatable cushion. The cushions are inflated semi-periodically such that one half of the heating mechanism is raised and then the other half of the heating mechanism is raised relative to the central plane. Thus, the temperature-controlled article is first compressed with a first half and then compressed with a second half relative to the central plane. A disadvantage of the installation is that it is relatively expensive to temporarily and partially compress the temperature-controlled article. The frequency or acceleration is relatively limited.

[0005] An installation for regulating the temperature and thawing a temperature-controlled item is known from EP 0 318 924 B1. In the installation, the temperature-controlled item is arranged between two heating mechanisms of a heating module. The heating mechanisms are formed as plastic bags. A warm liquid is circulated by a pump. A crank is arranged on the peripheral side of the heating mechanisms. The crank is rotated by a motor, compressing alternately the peripheral side of the upper heating bag and the peripheral side of the lower heating bag, so that the warm liquid contained in the heating bags is moved away from the crank. This generates moving vibrations in the heating bags, which can be transmitted to the temperature-controlled item. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] U.S. Patent No. 6,748,164 [Patent Document 2] U.S. Patent No. 8,012,416 [Patent Document 3] European Patent No. 0318924 Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to improve an installation for adjusting the temperature and thawing temperature-controlled articles, so that the efficiency of the temperature adjustment can be further improved in a simple manner. [Means for solving the problem]

[0008] This problem is solved according to the invention in the generic sense of claim 1 by characterising in that the actuator is configured as a mechanical adjusting element, which ideally bears directly against the temperature-controlled article and which is controllable so that it is moved cyclically and / or acyclically.

[0009] The inventive arrangement allows for a proper and direct movement control of the temperature-controlled article by directly abutting the mechanical regulating element on the temperature-controlled article. As a result, the heat transfer from the heating mechanism to the temperature-controlled article can be accelerated. Preferably, the movement preset by the regulating element can be directly and quickly transferred to the temperature-controlled article. Unwanted disturbances during the intervention of another component on the movement from the regulating element to the temperature-controlled article can be avoided. In particular, the invention allows for a relatively quick replacement of the normally heated part constituting the outer region of the temperature-controlled article with the normally cold part constituting the core region of the temperature-controlled article. Thus, a relatively fast mixing of the temperature-controlled article is ensured. The temperature-controlled article can be configured, for example, as a liquid or gel contained in a bag. Thus, the invention allows for a relatively fast mixing of the liquid or gel. The temperature-controlled article can be heated by electromagnetic induction or by radiation (infrared, microwave) or by airflow. According to the invention, the mechanical regulating element is mechanically directly bonded to the temperature-controlled article. Thus, particularly intermittent moving impulses can be transmitted directly to a portion of the temperature controlled article.

[0010] According to a preferred embodiment of the invention, the mechanical adjustment element is controllable so that a pivoting movement is performed. In this case, the temperature-controlled article is partially deflected in different paths from its extension plane. The temperature-controlled article is deformed or "kneaded". As a result, the frozen core and the already thawed part of the temperature-controlled article flow or move inside. In particular, the pivot axis extends in the area of ​​the central plane or the transverse central plane. As a result, the temperature-controlled article is pivoted back and forth around its central plane like a boat paddle. As a result, the frozen part and the already thawed part of the temperature-controlled article can be moved constantly in the already melted part of the temperature-controlled article during the back and forth movement. This causes a non-uniform flow in the temperature-controlled article. In this case, the cold liquid flows along the surface of the temperature-controlled article, which causes a higher temperature gradient from the heating element towards the temperature-controlled article. It has been demonstrated that the defrosting time can be reduced by 30%.

[0011] According to a preferred embodiment of the present invention, the mechanical adjustment element is flat. The adjustment element can be adapted to the shape of the temperature-controlled article, so that a linear and / or flat contact is obtained between the adjustment element and the temperature-controlled article. Preferably, the adjustment element is flat, so that the adjustment element can be positioned in a space-saving manner between the temperature-controlled article and the heating element.

[0012] According to a further configuration of the invention, the regulating element is formed as a rod element consisting of a number of rods surrounding an opening which allows the heating mechanism to be brought into direct contact with the temperature-controlled article, in which case the heat transfer surface between the heating mechanism and the temperature-controlled article is reduced as small as possible compared to an installation without the regulating element.

[0013] According to a further configuration of the invention, the regulating element has a peripheral surface adapted to a peripheral surface of the temperature controlled article, such that by adapting to the dimensional proportions of the temperature controlled article, the pivoting movement can be performed with the application of a relatively small force.

[0014] According to a further configuration of the invention, the adjusting element is coupled to an actuator, in particular a stepping motor, which controls the adjusting element such that it is pivoted periodically and / or aperiodically back and forth between a maximum and a minimum adjustment angle. In particular, the pivoting movement has a constant amplitude. Instead of a motor, the actuator may be configured as a magnetic or pneumatic mechanism, whereby the temperature-controlled article is subjected to a periodic and uniform back and forth or paddle movement about a pivot axis. Alternatively, this movement may be performed with a time-varying amplitude.

[0015] According to a further configuration of the invention, the adjusting element is controllable such that it is continuously swiveled at a frequency of 0.1-25 Hz. It has been found that the best temperature adjustment results are obtained within this frequency range. In particular, a reduction in the defrosting time is achieved by applying the impact force intermittently and periodically or anti-periodically partially at several points of the temperature-controlled article. For this purpose, the adjusting element acts at different points of the temperature-controlled article with high acceleration.

[0016] According to a further configuration of the invention, the regulating element is moved linearly and / or pivotally with an amplitude in the range of + / - 2 mm to + / - 100 mm, for example + / - 10 mm to + / - 30 mm, in particular + / - 25 mm, which relatively small deviations have been found to produce good temperature regulating results.

[0017] According to a further configuration of the invention, the rods of the rod element are formed from a wire. Preferably, the metal wire reduces losses in terms of heat transfer. Also, the wire has a low mass, so that the heat capacity of the rod element is low. Rapid movements and high accelerations acting directly on the temperature-controlled item can be achieved due to the rigid or stable structure of the wire. If the heating mechanism is formed as a fluid cushion, not only the temperature-controlled item but also the fluid cushion can be mixed or stimulated at the same time. The regulating element can therefore be easily manufactured. The regulating element exhibits sufficient rigidity for the intended use.

[0018] According to a further aspect of the invention, multiple rod elements may be arranged along the pivot axis, preferably forming smaller enclosed surfaces by which the pivoting movement is directly transmitted to the temperature controlled article.

[0019] According to a further configuration of the invention, the heating mechanism can be formed as a temperature-regulating cushion or as a gel cushion. The contents of the heating mechanism are heated electrically. Alternatively, the heating mechanism can be formed by a plastic bag containing a liquid temperature-regulating medium. In this case, the medium is circulated by a pump. The regulating element of the invention can be used universally regardless of the function of the heating mechanism.

[0020] In order to solve this problem, the present invention in relation to the generic concept of claim 18 is characterized in that the duration, amount and / or strength of action of the adjusting element is changed depending on a preset point in the time interval and / or on operating or process parameters of the temperature-controlled article.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. [Brief description of the drawings]

[Figure 8] 1 illustrates a displacement / time chart according to a first motion transition of the present invention. [Figure 9] 4 illustrates a displacement / time chart according to a second motion transition of the present invention. [Figure 10] FIG. 2 is a front view of multiple adjustment elements. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The equipment for temperature regulation and thawing of a temperature-controlled article 1 of the present invention comprises a housing 2. The upper side of the housing 2 is configured as a hinged lid 3. A lower base chamber 4 is provided in the interior space of the housing 2. An electronic control device and other components are provided in the base chamber 4 to enable temperature regulation in a temperature regulation chamber 5 arranged above the base chamber 4. The housing 2 comprises an operating element 6 and a display device 7 on the vertical front side of the base chamber 4. As a result, the thawing device formed from the housing 2 can be operated by a person.

[0024] The temperature regulation chamber 5 has a fixed bottom 8, which at the same time forms a partition to the base chamber 4. The heating mechanism consists in particular of a first heating element 9 present on the bottom 8 and a heating module 10 belonging to this first heating element 9 and arranged in the base chamber 4. A mechanical adjustment element 12 is arranged vertically on the upper surface 11 of the lower heating element 9. In the operating state of the defrosting device with the lid 3 closed, the temperature regulation chamber 5 is vertically arranged in a layered structure as shown in FIG. 3. The temperature-controlled article 1 abuts vertically upwards against the first adjustment element 12. A second adjustment element 13 abuts above the temperature-controlled article 1. The temperature regulation chamber 5 is arranged vertically in the longitudinal center plane L of the temperature-controlled article 1. T The temperature-controlled article 1 has a structure ideally symmetrical with respect to the temperature-controlled article 1. One adjusting element 12, 13 and one heating element 9, 14 abutting against the adjusting element are disposed on both sides of the article 1 to be temperature-controlled.

[0025] The temperature-controlled article 1 comprises, for example, a plasma or blood material enclosed in a bag as a containment vessel. Ideally, the bag of the temperature-controlled article 1 is relatively simple in design. To this end, the temperature-controlled article 1 has two opposing side surfaces 15, 15' and a number of constricted surfaces 16 arranged around the periphery. These constricted surfaces 16 join the opposing side surfaces 15, 15'. These side surfaces 15, 15' are particularly formed in a rectangular shape.

[0026] Alternatively, the temperature-controlled article 1 may be polygonal with different or equal sides. For example, the temperature-controlled article 1 may be pear-shaped or cubic, rump-shaped. In this case, the temperature-controlled article 1 is loaded into the temperature-regulating chamber 5. In this case, the temperature-controlled article 1 is clamped by the regulating elements 12, 13 and / or the heating elements 9, 14. Due to the particularly flexible structure of the temperature-controlled article, flat sides may occur at least when the temperature-controlled article is in a state of continuing to thaw. As a result, the heat transfer surface is increased compared to the initial state.

[0027] For better illustration, in Fig. 3, the components are arranged spaced apart from each other. In reality, these components are closely adjacent to each other, overlapping each other. Thus, the lower first adjustment element 12 is directly and planarly joined to the lower side 15 of the temperature-controlled article 1 and is adjacent to the upper surface 11 of the lower first heating element 9. The upper second adjustment element 13 is directly and planarly joined to the upper side 15' of the temperature-controlled article 1 and is adjacent to the lower surface 17 of the upper second heating element 14.

[0028] The first and second adjusting elements 12, 13 can in particular be made of the same structure. Each of these adjusting elements has two paddle parts 18 arranged distributed in the longitudinal direction of the adjusting elements 12, 13. The paddle parts 18 each consist of a rod 19 extending in a rectangular shape. The paddle parts 18 are connected to one another by a connecting rod 20. This connecting rod 20 can extend continuously from the first end to the second end of the adjusting elements 12, 13. A T-shaped piece 21 is connected to one end of the connecting rod 20. This T-shaped piece 21 is accommodated, for example in a locked manner, in a holder 22. For this purpose, the holder 22 has a groove. A transverse rod on the end side of the T-shaped piece 21 is accommodated in this groove. A hollow cylinder 23 is connected to the holder 22. A shaft of a motor (not shown) can be fixedly engaged in this hollow cylinder 23. In the working position, the hollow cylinder 23 or shaft extends coaxially to the connecting rod 20, which therefore extends in a pivot axis S. The motor is used as an actuator. Alternatively, the actuator may be configured pneumatically or magnetically, for example as a lifting magnet or a rotary magnet.

[0029] The first adjustment element 12 and the second adjustment element 13 are adjusted by a motor to a maximum adjustment angle φ MAX and the minimum adjustment angle -φ MAX These adjusting elements are connected to the motor via a shaft or via a gear unit.

[0030] 1, the adjusting elements 12, 13 are journalled at different heights in the centre of the temperature-conditioning chamber 5. In general, the pivot axis S runs parallel to the side wall 24 of the temperature-conditioning chamber 5 and perpendicular to the rear wall 25 and the front wall 26 of the temperature-conditioning chamber 5. The holder 22 of the adjusting elements 12, 13 is arranged in the area of ​​the rear wall 25.

[0031] The pivot axis S is the central plane of the temperature-controlled article 1, i.e., the lateral central plane Q TThe adjusting elements 12, 13 are pivotally supported so as to be pivotable back and forth about this pivot axis S. Thus, a first half 27 of the paddle portion 18 of the adjusting elements 12, 13 is assigned to a first half 28 of the temperature-controlled article 1. A second half 27' of the paddle portion 18 of the adjusting elements 12, 13 is assigned to a second half 28' of the temperature-controlled article 1. Both halves 27, 27' or 28, 28' are aligned with the pivot axis S or the transverse central plane Q. T are arranged symmetrically with respect to

[0032] The adjusting elements 12, 13 arranged offset in the direction of the pivot axis S are in particular controlled identically, so that within a half period T / 2, the first half 27 of the paddle part 18 is rotated by a positive angle φ in the direction +φ MAX and the second half 27′ is rotated in the direction −φ by a negative angle −φ. MAX In this case, the first half 27 of these adjusting elements 12, 13 is pivoted upwards, while the second half 27' of these adjusting elements 12, 13 is pivoted downwards. D is applied to the opposing sides 15, 15' and opposing halves 28, 28' of the temperature-controlled article 1. This allows a non-uniform flow to be suitably generated in the temperature-controlled article 1. In this case, for example, the frozen core 29 moves back and forth and is surrounded by a non-uniform flow of already thawed liquid 30.

[0033] This allows for very high temperature gradients to be generated. The frozen core 29 is the part of the temperature-controlled article 1 that is present in the core region of the temperature-controlled article 1. The liquid 30 surrounding the core 29 corresponds to the part of the temperature-controlled article 1 that is present in the outer region of the temperature-controlled article 1. The temperature-controlled article 1 is in a frozen state at the beginning of the temperature adjustment process. In this case, both the outer region and the core region of the temperature-controlled article are in a solid, cohesive state, i.e., exhibit a temperature below 0°C. By applying the equipment of the present invention to the temperature-controlled article 1 until the temperature-controlled article 1 exhibits the desired temperature at the end of the temperature adjustment process, the outer region of the temperature-controlled article 1 thaws relatively quickly, and the temperature-controlled article 1 moves quickly with a high acceleration, so that the temperature-controlled article 1 is completely thawed.

[0034] As can be seen from FIG. 3, the pivot axis S of the adjustment elements 12, 13 is aligned with the longitudinal center plane L of the temperature-controlled article 1. T The temperature-controlled article 1 is traversed in a projection direction perpendicular to the axis of the graph.

[0035] Generally, the paddle portion 18 of the regulating elements 12, 13 has an enclosing surface that is smaller than the enclosing surface of the temperature controlled article 1.

[0036] According to another embodiment of the present invention, multiple temperature controlled articles 1 may be assigned to multiple paddle sections.

[0037] As can be seen from FIG. 4, the peripheral rod 19′ extending parallel to the pivot axis S has a maximum deflection of ±S with respect to the initial position or initial height. MAX The paddle portions 18 are rotated, for example, periodically around the rotation axis S so that the paddle portions 18 swing between the longitudinal center plane L of the temperature-controlled article 1. T The maximum deflection S MAX ,-S MAX may be within the range of + / - 30 mm, in particular within the range of + / - 25 mm.

[0038] Each of the multiple peripheral rods 19' is arranged to have a width b of the temperature-controlled article 1 relative to the pivot axis S. T The interval a corresponds to 0.2 to 0.7 times half of the above.

[0039] In this embodiment, the mechanical adjustment elements 12, 13 or the paddle portion 18 are formed flat.

[0040] According to another embodiment of the invention not shown, the contour of the regulating elements 12, 13 or the paddle portion 18 may be, for example, arc-shaped and / or spoon-shaped in order to better fit the shape of the temperature-controlled article 1.

[0041] The rods 19, 19' of the paddle portion 18 define an opening 32 into which the flexibly formed temperature-controlled article 1 and / or the heating element 9, 14 can be partially inserted. The temperature-controlled article 1 is thus in direct contact with the heating element 9, 14 in the area of ​​the opening. The regulating elements 12, 13 according to this embodiment are generally formed as rod elements, which essentially results in a direct contact between the heating element 9, 14 and the temperature-controlled article 1.

[0042] According to another embodiment of the invention, all surfaces of the paddle portion 18 may be rigidly or flexibly formed from a thermally conductive material. In some cases, the generally planar adjustment element or paddle portion 18 may be composed of multiple rigid segments joined together, for example, in a film hinge manner.

[0043] The motor rotates the adjusting elements 12, 13 at a frequency in particular in the range of 0.5 to 5 Hz, at which frequency heat can be optimally transferred into the temperature-controlled article 1.

[0044] Each of the heating elements 9, 14 comprises a plastic bag in which a temperature-regulated liquid medium is circulated by a pump (not shown). The pump and heating coils for regulating the temperature of the liquid medium are arranged in the base chamber 4.

[0045] According to another embodiment of the invention, the heating elements 9, 14 may be formed by electrically heated thermoregulating cushions or gel cushions, respectively, so that the required construction space is relatively small.

[0046] The rods 19, 19' of the adjustment elements 12, 13 consist of wire.

[0047] According to another, not shown, embodiment of the invention, the defrosting device may have only one regulating element 12, 13 arranged above or below the temperature-controlled article 1. In contrast to the above embodiment, the pressing force F D is not always applied to both sides 15, 15' of the temperature-controlled article 1, but is applied alternately to only one side 15, 15', i.e., applied onto the first side 15 during the first half period T / 2 and applied onto the second side 15' during the second half period T / 2.

[0048] According to an embodiment not shown, the motor can also be configured as a stepper motor, by means of which the shaft is rotated by a predefined angle. The motor curve with the motor current I shown in FIG. 4 is not sinusoidally displaced in this case.

[0049] As can be seen from FIG. 3 and FIG. 4, for example, the periodic pressing force F D is applied on both sides of the temperature-controlled article 1, i.e., on the first side 15 and on the second side 15'. Based on this configuration, the adjusting elements 12, 13 are pivoted synchronously and / or in the same direction in the same pivoting direction. Thus, when the first half 27 of the paddle portion 18 is pivoted upward from its initial position in the plane A towards the temperature-controlled article 1, the pressing force F D11 is applied by the lower adjustment element 12, and when the second half 27' of the paddle portion 18 pivots downward toward the temperature-controlled article 1, a pressing force F D22 is applied by the upper adjustment element 13. The adjustment elements 12, 13 are aligned at a maximum angle φ MAX The maximum deviation S MAXWhen the force F is reached, the movement is reversed. D11 ,F D22 After half a period T / 2, the initial position A is reached and the pressing force F D12 acts on the second half 27′ of the lower side surface 15 by another half 27′ of the lower adjustment element 12, while the pressing force F D21 acts on the first half 27 of the temperature-controlled article 1 by the first half 27 of the upper adjusting element 13. In FIG. 4, this action is illustrated by the corresponding force arrows. The paddle halves 27, 27′ thus act like a pivoting lever with a number of openings. The pressing force F D always acts on the lower side surface 15 and the upper side surface 15' of the temperature-controlled article 1. In this case, the pressing force F D11 and F D22 or pressure F D21 and F D12 But the lateral center plane Q T It acts asymmetrically on the temperature-controlled article 1.

[0050] If only one adjusting element 12, 13 is provided, the pressing force F D11 ,F D12 or F D21 ,F D22 However, both halves 28, 28' of side 15 or 15' of temperature-controlled article 1 are acted on alternately by half 27, 27' of paddle portion 18 from only one side.

[0051] According to another embodiment of the invention, not shown, both adjusting elements 12, 13 can also be controlled in such a way that they are not pivoted in the same direction but in opposite directions (counter-periodically). Dare generated alternately between the lower half 28 and the upper half 28 of the side 15 of the temperature-controlled article 1 and the lower half 28' and the upper half 28' of the side 15 of the temperature-controlled article 1. The first half 27 of the first regulating element 12 is pivoted upwards, while the first half 27 of the second regulating element 13 is pivoted downwards. The second half 27' of the first regulating element 12 is pivoted downwards, while the second half 27' of the second regulating element 13 is pivoted upwards. The symmetrical or opposite movements of these regulating elements 12, 13 result in a more intensive movement of the frozen core 29 of the temperature-controlled article 1 and of the already thawed components. In this case, the same effect is preferably achieved with a reduced maximum pivot angle φ compared to the embodiment with only one regulating element. MAX ,-φ MAX or maximum swing S MAX ,-S MAX This can be achieved with

[0052] Alternatively, the adjusting elements 12, 13 may be moved periodically and / or aperiodically in the same direction and / or in opposite directions to each other, so that the deformation forces on the temperature-controlled article 1 or on the core 29 of the temperature-controlled article 1 and the already thawed surrounding liquid 30 of the temperature-controlled article 1 are further increased.

[0053] According to an embodiment not shown, instead of a periodic movement at least one of the adjusting elements 12, 13 can also be moved aperiodically or moved in aperiodically pivoting manner.

[0054] According to an embodiment not shown, at least one of the adjustment elements 12, 13 may be moved both periodically and aperiodically, or alternatively, the adjustment element 12, 13 may be moved linearly.

[0055] According to an embodiment not shown, the heating element is integrated into the adjustment element. Advantageously, the space required can be significantly reduced. The heating element can be configured, for example, as a thermoregulating cushion or gel cushion, the contents of which are electrically heated. If the heating element is configured as a plate heater with a solid heating surface, it can be used at the same time as an adjustment element.

[0056] According to the embodiment of the adjusting element according to FIG. 6, which is also shown in FIG. 1, the adjusting element 12, 13 consists of a number of wide and narrow parts 40, 41, which are arranged offset from one another along the pivot axis S. The wide parts 40 of the adjusting element 12, 13 have a pair of peripheral rods 19' which extend with a comparatively large distance d2. The peripheral rods 19' extend parallel to the pivot axis S. A number of rods 19, which extend approximately perpendicular to the pivot axis S, are connected to the peripheral rods 19'. The rods 19 in abutment with the peripheral rods 19' form an O-shaped paddle section 18. The O-shaped paddle section 18 is formed as an open paddle with an opening.

[0057] A narrow part 41 having a number of rods 19" extending parallel to the pivot axis S connects to the wide part 40. The rods 19" are arranged at a relatively small distance d1 from one another. The rods 19" of the narrow part 41 extend in the direction of the pivot axis. The rods 19" of the narrow part 41 connect to rods 19 of the wide part 40 extending perpendicular to the pivot axis or are connected to actuators at the ends of the adjustment elements 12, 13.

[0058] As can be seen from FIG. 6, the first widened portion 40′ abuts against the side surfaces 15, 15′ of the temperature-controlled article 1 that are arranged at right angles to the pivot axis S. The first widened portion 40′ is adapted to the temperature-controlled article 1 such that the peripheral rod 19′ extends within a range of + / - 20%, in particular + / - 10%, of the halves 28, 28′ of the temperature-controlled article 1 or extends close to or on the center of gravity of said halves 28, 28′. In this embodiment, the spacing g1 of the first half 28 is 8 cm and the spacing g2 of the second half 28′ is 7 cm. The temperature-controlled article 1 is therefore arranged so that the lateral central plane Q of this temperature-controlled article 1 is oriented in such a way that the peripheral rod 19′ extends within a range of + / - 20%, in particular + / - 10%, of the halves 28, 28′ of the temperature-controlled article 1 or extends close to or on the center of gravity of said halves 28, 28′. In this embodiment, the spacing g1 of the first half 28 is 8 cm and the spacing g2 of the second half 28′ is 7 cm. T The size of the spacing d2 of the peripheral rods 19' is selected so that the peripheral rods 19' can be deflected by applying a suitable force about a pivot axis S extending within the halves 28, 28'. The line of action induced by the peripheral rods 19' in the halves 28, 28' in the direction of the pivot axis S thus extends within the area of ​​the center of gravity of these halves 28, 28'.

[0059] The second widened part 40" of the adjusting element 12, 13 acts on two temperature-controlled articles 1 arranged in contact with each other. All temperature-controlled articles 1 are arranged in a common plane. A first half 44 of this widened part 40" is assigned to the second temperature-controlled article 1 and a second half 44" of this widened part 40". These halves 44, 44" of this widened part 40" are arranged symmetrically with respect to the pivot axis S. A number of peripheral rods 19' of these halves 44, 44' each have an equal half spacing d2 / 2 with respect to the pivot axis S. These peripheral rods 19' extend in the region of the center of gravity of the respective temperature-controlled article 1 or close to or in the region of the axis of symmetry X1 of said temperature-controlled article 1.

[0060] According to another embodiment of the invention according to FIG. 5, instead of a continuous deflection (harmonic and / or linear vibration) of the adjusting elements 12, 13, an impulse-like deflection is carried out. For example, the peripheral rod 19′ is deflected at a time t 1The adjustment element 12,13 can then be abruptly deflected from 0 cm to 15 cm relative to the rotational direction. The adjustment element 12,13 then remains stationary for a period Δt2 before returning again to the initial position with an abrupt but slower absolute acceleration relative to the time t2. After reaching the initial position at time t3, the adjustment element 12,13 remains stationary until time t4 before the same deflection movement is performed in the other turning direction. According to this embodiment, abrupt periodic and / or aperiodic deflections are performed. In this case, the adjustment element 12,13 is stationary at the maximum deflection position in the period Δt2 and at the initial position in the period Δt1.

[0061] The maximum swing and / or frequency 1 / T and / or acceleration of the movement of the regulating element 12, 13 can be selected depending on the actual temperature of the temperature-controlled article 1 relative to a preset threshold temperature or a preset fixed point in time. The control of the regulating element 12, 13 does not have to be performed periodically or aperiodically or with the same impulse sequence or with the same swing progression over the entire duration of the temperature regulation process. The amplitude of the change or the frequency and the acceleration can be changed depending on the temperature-controlled article 1 to be temperature-regulated. Different movement profiles can therefore be selected for different temperature-controlled articles 1. For example, at the beginning of the temperature regulation process, the frequency of the impulse swings can be increased until the frozen core 29 of the temperature-controlled article 1 contracts to its minimum volume. Subsequently, the frequency of the impulse sequence can be decreased. Alternatively, the maximum swing can be selected relatively small during a first period of the temperature regulation process until the outer area of ​​the temperature-controlled article is thawed and in a liquid state. Then, during a second period of the temperature regulation process, the maximum swing of the regulating element 12, 13 can be increased. As a result, the degree of agitation within the temperature-controlled article may be increased and thus the thawing process may be accelerated. Then, for a further period of the temperature adjustment process, the maximum deflection and / or the frequency and / or the acceleration may be reduced again until the temperature-controlled article 1 reaches the desired target temperature.

[0062] Instead of servo motors, stepping motors or DC / AC motors with gearing or electrically operated lifting magnets / rotary magnets can also be used as actuators to control the adjusting elements 12, 13. Alternatively, pneumatically or hydraulically operated cylinders can be used to control the adjusting elements 12, 13.

[0063] According to another embodiment of the present invention, instead of a refrigerated temperature controlled item, any chemical or substance in a liquid or viscous state may also be set to a desired temperature.

[0064] Temperature controlled items 、 In the case of a relatively large surface area or a relatively large volume of material, the temperature-controlled article is oscillated, in particular at multiple positions on opposing sides, only by linearly displaced adjusting elements. Thus, in particular multiple points of action arise on the temperature-controlled article. The adjusting elements act on these points of action in a common adjustment direction or parallel to one another. In this case, in particular, multiple adjusting elements can be arranged in a cascade with a shift perpendicular to the adjustment direction of the adjusting elements. In this case, the adjusting elements can be controlled or act on the temperature-controlled article with a time shift perpendicular to the adjustment direction.

[0065] In Figure 8, the temperature adjustment process according to the first movement profile is shown. Basically, Constant preset or actual Depending on the operating or process parameters, a pressing force can be applied partially to the temperature-controlled article 1 by the regulating elements 12, 13. The duration, the magnitude and / or the strength (acceleration) of the action of the regulating elements 12, 13 can be varied during the temperature regulation process.

[0066] FIG. 8 shows how the temperature-controlled item (plasma) is heated from a frozen state to a preset target temperature T Soll The migration profile for thawing to a liquid state at time t A1 and time t A2In the preceding time interval between t and t, the system is still in an initial state of being almost completely frozen, and no movement has yet been performed. A2 and time t A3 During a first time interval between T 1 and T 2 , a part of the temperature-controlled article is already liquefied and the regulating elements 12, 13 are operated, for example periodically, with a first frequency, a reduced first amplitude and a first absolute slope, so that the temperature of the temperature-controlled article 1 reaches close to 0° C. Z2 But at time t A3 At time t A3 The first time interval T Z1 The adjustment elements 12, 13 are moved, for example, periodically with a larger amplitude A2 and a frequency equal to the second absolute gradient of the deflection (acceleration) relative to the amplitude A2. A3 or Constant preset or actual The operating or process parameters are changed depending on the change in the load of the regulating element 12, 13, for example. The change in the load can be recognized by a changed motor current of the actuator. The gradient with respect to the amplitude of the regulating element 12, 13 means the gradient or acceleration of the displacement progression / deflection of the regulating element 12, 13, which runs from the zero point to the amplitude A1, A2. Z2 As can be seen, the absolute value of the slope of the deflection towards the amplitude A2 or -A2 is maximum, while the return movement towards the zero line is performed with a smaller absolute slope or a smaller absolute acceleration. In this case, the duration, amount and / or strength of action of these adjusting elements are changed depending on a preset point in the time interval TD and / or on the operating or process parameters of the temperature-controlled article 1 .

[0067] According to another embodiment of the movement profile according to Fig. 9, the regulating elements 12, 13 are regulated on a temperature-controlled article 1 that is in a cooled but not frozen state. The temperature-controlled article 1 can be manufactured as an additive drug. The temperature-controlled article 1 is therefore in a liquid or viscous state at the beginning of the temperature regulation process. The temperature-controlled article 1 is regulated at a target temperature T Soll Therefore, at time t B1 At time t B2 The first time interval T that ends Z1′Within the period, the adjustment element is moved, for example, periodically, with a first frequency, a first amplitude, and a first absolute gradient (acceleration) relative to the maximum deflection A1′, −A1′. Krit When the second time interval T Z2′ 2, the adjusting elements 12, 13 are moved with the same amplitudes A1, -A1', but with a smaller frequency and with a smaller acceleration or smaller absolute gradient relative to the maximum deflection A1', -A1'.

[0068] As can be seen from Fig. 10, several adjusting elements 12, 13, for example as shown in Fig. 6, can be arranged in pairs next to each other at a preset distance from each other in the temperature-conditioning chamber 5 (see bottom left of Fig. 10). Alternatively, only one adjusting element 50 with a rectangular rod 19 having several peripheral rods 19' extending symmetrically with respect to the pivot axis S can be arranged in the temperature-conditioning chamber 5. These peripheral rods 19' extend in particular continuously and linearly over all sides of this adjusting element 50.

[0069] According to alternative embodiments, the adjustment element may comprise a circular rod 51 (circular paddle portion) (see bottom center of FIG. 10) or an elliptical rod 52 (elliptical paddle portion) (top center of FIG. 10) (see FIG. 10).

[0070] According to another embodiment, an adjustment element 53 can be provided having a diamond-shaped paddle portion 54 (see FIG. 10, top right).

[0071] According to another embodiment, an adjustment element 55 can be provided which has a number of paddle portions 56 arranged asymmetrically with respect to the pivot axis S.

[0072] Thus, depending on the dimensions of the temperature controlled article 1, differently shaped adjustment elements 12, 13, 50, 51, 53, 55 may be used.
