Description

[0001] incubator

[0002] The invention relates to an incubator with an incubation chamber and a temperature control device for controlling the temperature of the incubation chamber.

[0003] Such incubators are already known in practice in various designs. Incubators are used, for example, to create and maintain a specific microclimate in the incubation chamber, thereby providing specific conditions for biological and / or biochemical processes.

[0004] A uniform temperature distribution within the incubation chamber is particularly important. Temperature differences within the incubation chamber are desired to ensure a microclimate with the most uniform temperature possible.

[0005] The object of the invention is therefore to provide an incubator of the type mentioned at the outset which enables the temperature control of its incubation chamber with the most uniform temperature distribution possible in the incubation chamber.

[0006] To solve this problem, an incubator having the features of the first independent claim directed to such an incubator is first proposed.

[0007] To achieve the objects, an incubator with an incubation chamber and a temperature control device for temperature control in the incubation chamber is proposed, wherein the temperature control device has a fan and, on either side of the fan, at least one cooling line arrangement through which coolant flows. Due to the fact that, on either side of the fan, at least one cooling line arrangement through which coolant flows is present, a particularly homogeneous temperature distribution is achieved in the incubation chamber of the incubator during cooling operation. With the help of the fan, the incubation chamber of the incubator can be cooled in recirculation mode, wherein the air blown into the incubation chamber by the fan is cooled by the cooling line arrangements arranged on either side of the fan.

[0008] Each of the at least two cooling line arrangements of the temperature control device comprises a cooling line. During cooling operation of the incubator, coolant flows through the cooling lines and can extract heat from the air flowing over or surrounding the cooling lines.

[0009] The use of two cooling line arrangements through which coolant flows, each of which can consist of a cooling line through which coolant flows, has the advantage that the effective cooling line length offered by the temperature control device can be distributed over at least two separate cooling line arrangements.

[0010] This has the effect that a temperature gradient between a start and an end, in particular between a coolant inlet and a coolant outlet, of the respective cooling line arrangement is lower than in a single cooling line arrangement, which then has a correspondingly longer cooling line.

[0011] The coolant flowing through the cooling line arrangements thus experiences a lower temperature rise between the coolant inlet and outlet of the respective cooling line arrangement on either side of the fan. This results in a more uniform temperature across the cooling line arrangements, which promotes homogeneous cooling of the air distributed by the fan in recirculation mode throughout the incubation chamber.

[0012] In one embodiment of the incubator, at least one cooling line arrangement is arranged on either side of a vertical plane of the incubator, in which a rotational axis of the fan runs. The fan can then preferably be arranged centrally between the at least two cooling line arrangements.

[0013] The cooling duct arrangement on one side of the vertical plane can be mirror-symmetrical to the cooling duct arrangement on the other side of the vertical plane. This also promotes homogeneous cooling of the air distributed by the fan in the incubation chamber.

[0014] The fan can preferably be a radial fan. The radial fan can blow air radially outward relative to its rotation axis, i.e., into areas where at least two cooling line arrangements are located. The air can then flow over the cooling line arrangements, transferring heat to the cooling line arrangements and being cooled to the desired temperature.

[0015] The vertical plane along which the fan's rotation axis runs can preferably be a central plane of the incubator's incubation chamber. The vertical plane, as the central plane, then divides the incubation chamber into two equal-sized compartments. The cooling line arrangements on either side of the vertical plane running through the center of the incubation chamber are then mirror-symmetrical to one another, which also promotes homogeneous cooling of the incubation chamber.

[0016] In a particularly advantageous embodiment of the incubator, it is provided that each cooling line arrangement has its own coolant inlet and its own coolant outlet, which are connected to one another via a cooling line of the respective cooling line arrangement.

[0017] As already explained above, each cooling line arrangement can thus be formed from a cooling line which connects a coolant inlet of the cooling line arrangement, via which coolant enters the cooling line arrangement, and a coolant outlet of the cooling line arrangement, via which the coolant exits the cooling line arrangement.

[0018] When entering the cooling line arrangement, the coolant supplied via the coolant inlet has a lower temperature than when exiting the coolant outlet. Along the course of the cooling line arrangement and its cooling line, the temperature of the coolant increases due to heat absorption from the air flowing over the cooling line arrangement until it exits the coolant outlet of the cooling line arrangement.

[0019] As already explained above, the temperature gradient that occurs between the coolant inlet and the coolant outlet can be minimized by dividing the total length of the existing cooling lines into at least two cooling line arrangements, which is conducive to a homogeneous temperature distribution in the incubation chamber.

[0020] The coolant inlet of the respective cooling line arrangement can have a smaller distance to the fan and in particular to the vertical plane than the coolant outlet of the cooling line arrangement.

[0021] This ensures that the areas of the cooling duct arrangements that are closer to the fan have a lower temperature when the incubator is in cooling mode than the parts of the cooling duct arrangements that are further away from the fan or from the vertical plane mentioned above. The amount of air passing over the cooling duct arrangements on both sides of the fan in recirculation mode can be directed in the direction of increasing temperature via the cooling duct arrangements, particularly if the fan is a radial fan. This also promotes a homogeneous temperature distribution in the incubation chamber. In recirculation mode, the air is then sucked in from the incubation chamber by the fan and directed in a radial direction with respect to the axis of rotation of the fan over the at least two cooling duct arrangements. The air is cooled more deeply with each circulation until it has reached the target temperature.With each circulation, the air exits the fan and initially encounters the coldest areas of the cooling duct arrangements, allowing it to be cooled quickly. The direction of air flow through the cooling duct arrangement toward an increasing surface temperature of the cooling duct arrangements promotes, through heat exchange, a further reduction in the temperature gradient that develops along the course of the cooling duct of the respective cooling duct arrangement.

[0022] In one embodiment of the incubator, it is provided that the coolant inlet and / or the coolant outlet of at least one cooling line arrangement are arranged in a horizontal plane below the rotation axis of the fan. In this case, it is possible for the coolant inlet and the coolant outlet of at least one cooling line arrangement to be arranged in the same horizontal plane. The fan and the cooling line arrangements can be arranged on a common inner wall, in particular on an inner rear wall, of the incubator. The inner rear wall of the incubator can be an inner wall of the incubator that faces away from an opening into the incubation chamber.

[0023] In an area, particularly the aforementioned inner wall, above the fan, duct sections of the cooling duct arrangements can be arranged. This ensures that air discharged upwards by the fan reaches the sphere of influence of the cooling duct arrangements and can be cooled there.

[0024] In one area, particularly the aforementioned inner wall, above the fan, the cooling duct arrangements can be spaced closer to the vertical plane and / or to one another than in one area, particularly the inner wall below the fan. This ensures that the cooling duct arrangements enclose the fan on the sides and above. Air that rises into this area due to convection or microthermal forces at a higher temperature, as long as the temperature distribution in the incubator is not yet homogeneous, can then be cooled particularly efficiently to the desired target temperature.

[0025] The line sections of the cooling line arrangements can be arranged in meanders. Such a cooling line arrangement can also be referred to as a cooling coil. It is preferred if the meanders within a cooling line arrangement are evenly spaced from one another and / or if the cooling line arrangements have a higher meander density above the fan than below the fan.

[0026] In areas where the cooling pipe arrangements have a higher meander density than in other areas, the cooling capacity of the respective cooling pipe arrangement can be increased, which enables faster cooling of the air passed through the cooling pipe arrangement.

[0027] The distance between the cooling line arrangements above the fan can be at most as large as the smallest distance between two meanders within a cooling line arrangement. In this way, a homogeneous cooling field consisting of at least two sections of two cooling line arrangements is created above the fan, which correspondingly increases the cooling effect and cooling capacity of the cooling line arrangements in the particularly crucial area above the fan. In this area, the air can then be cooled particularly quickly due to the high cooling capacity, which in turn promotes rapid temperature control of the incubator's incubation chamber.

[0028] An area beneath the fan can be free of cooling line arrangements, in particular free of meanders of the cooling line arrangements, for example, over a width that corresponds at least to the diameter of the fan. The area can be bounded laterally by the cooling line arrangements.

[0029] If the area beneath the fan is free of cooling ducts, this prevents a cushion of particularly cold air from forming on the floor of the incubation chamber, which would make it difficult to achieve a homogeneous temperature distribution in the incubation chamber. The special design of the at least two cooling ducts thus enables the incubation chamber to be cooled from above. The fact that the density of the air increases with decreasing temperature can be used to create a homogeneous temperature distribution in the incubation chamber. Air cooled to a desired temperature can then sink from above in the incubation chamber, displacing even warmer layers of air upwards. This air can then reach the fan's detection area, be sucked in by the fan and passed through the cooling ducts for cooling until a homogeneous temperature is achieved in the incubation chamber.

[0030] The temperature control device of the incubator can comprise at least one, preferably electrical, heating line. The heating line can preferably be arranged on both sides of the fan and / or in heating meanders. With the help of the heating line, it is possible to heat the incubation chamber to a specific temperature above the ambient temperature using the fan in recirculation mode, if necessary. The formation of the heating line on both sides of the fan can promote a homogeneous temperature distribution within the incubation chamber.

[0031] To solve the problem, an incubator having the features of the second independent claim directed to an incubator is also proposed.

[0032] Accordingly, an incubator with an incubation chamber and a temperature control device for controlling the temperature of the incubation chamber is proposed, wherein the temperature control device comprises a fan and a, preferably electric, heating line arranged on both sides of the fan, wherein an area above the fan is free of heating line, but the heating line runs through an area below the fan. The area above the fan can be delimited laterally by heating line.

[0033] This incubator design enables uniform temperature control of the incubation chamber during heating operation. By arranging heating lines on both sides of the fan, the heating lines also run underneath the fan, but leaving an area above the fan free of heating lines, it is possible to achieve a particularly uniform temperature distribution within the incubation chamber during heating operation.

[0034] Air, which is guided by the fan over the heating cable, which is distributed around the fan in the manner described above, is heated as it passes over the heating cable and is then distributed in the heated state in the incubation room in recirculation mode.

[0035] By creating an area above the fan that is free of heating lines, convection-induced heat buildup or hotspots are avoided. Such a hotspot would counteract a homogeneous temperature distribution during heating operation within the incubation chamber. By not having a heating line above the fan according to the invention, such a hotspot is effectively avoided, which in turn promotes a uniform temperature distribution within the fan during heating operation.

[0036] If heating lines of the temperature control device are present on the sides and below the fan, air heated by the heating lines can be distributed by the fan in the incubation chamber in these areas in order to create a uniform temperature distribution.

[0037] It is advantageous if the heating cable is arranged in heating meanders. In particular, a field occupied by heating meanders of the heating cable can be formed on both sides of the fan. Below the fan, the heating cable can run in a straight line between the heating cable sections present on both sides of the fan, in particular the fields with the heating meanders.

[0038] The heating line can have a mirror-symmetrical structure with respect to the previously mentioned vertical plane, in which the rotational axis of the fan can also run. This also promotes homogeneous heating of the air supplied by the fan and thus a homogeneous temperature distribution during heating operation within the incubator's incubation chamber.

[0039] In this embodiment of the incubator, too, it can be provided that the fan and the cooling line arrangements and / or the heating line are arranged on a common inner wall, in particular on an inner rear wall, of the incubator. The heating line can be a single heating line, i.e., a one-piece construction. Because a heating line, particularly an electric one, i.e., a heating line through which current flows, does not have a significant temperature gradient between its beginning and its end, as is the case with a cooling line through which coolant flows, a one-piece heating line can be laid for the sake of simplicity. This can reduce the outlay on manufacturing the incubator.

[0040] In this version of the incubator, the fan is preferably a radial fan.

[0041] In one embodiment of the incubator, the fan and the heating line are arranged on a common inner wall, in particular a common inner rear wall, of the incubator. If the incubator has at least one cooling line arrangement, this can be arranged on the same inner wall of the incubator as the fan and the at least one cooling line arrangement or else on a different inner wall. The fan and the at least two cooling line arrangements and / or the aforementioned heating line can be arranged in a receiving space of the incubator that is separated from the incubation space by a partition wall. The incubator can have air passage openings, in particular on or in the partition wall, which connect the receiving space to the incubation space of the incubator. The air can thus be tempered in the receiving space and then distributed at a tempered temperature in the incubation space with the help of the fan.

[0042] The incubator may have air outlet openings, for example on or in the partition wall, through which tempered air in the receiving chamber can then enter the incubation chamber.

[0043] The invention also relates to an incubator which combines the features of both independent claims, that is to say an incubator with an incubation chamber and a temperature control device for temperature control of the incubation chamber, wherein the temperature control device has a fan and on both sides of the fan at least one cooling line arrangement through which coolant flows and at least one heating line which is arranged on both sides of the fan, wherein an area above the fan is free of heating lines, preferably wherein the area is delimited laterally by heating lines, and wherein the heating line runs through an area below the fan.

[0044] This incubator then enables a homogeneous temperature distribution in its incubation chamber both in heating and cooling mode.

[0045] The invention is described in more detail below with reference to exemplary embodiments, but is not limited to these exemplary embodiments. Further exemplary embodiments result from the combination of the features of individual or multiple claims and / or from the combination of individual or multiple features of the exemplary embodiments. They show:

[0046] Fig. 1 is a front view of an incubator according to the invention with the incubation chamber open and the partition wall removed to illustrate the cooling line arrangements and their respective relative position to a fan of the incubator on an inner wall of the incubator,

[0047] Fig. 2 is a front view of the incubator with the incubation chamber closed by a door,

[0048] Fig. 3 is a perspective view of an inner housing of the incubator shown in Figures 1 and 2 to illustrate the partition wall in the incubation chamber of the incubator, behind which the temperature control device with the two cooling line arrangements, the fan and the heating line are arranged in the receiving space of the incubator,

[0049] Fig. 4 is a further front view of the opened incubation chamber of the incubator with a view of the inner rear wall in the receiving chamber of the incubator to illustrate the arrangement of the heating line relative to the fan of the temperature control device,

[0050] Fig. 5 shows a further front view of the open incubation chamber of the incubator, looking toward the inner rear wall, illustrating the components of the temperature control device on the inner wall of the incubator's receiving chamber, namely the two cooling line arrangements, the fan, and the heating line. All figures show an incubator, designated as a whole by 1, which has an incubation chamber 2 and a temperature control device 3 for controlling the temperature of the incubation chamber 2.

[0051] The temperature control device 3 comprises a fan 4 and, on both sides of the fan 4, a cooling line arrangement 5 and 6, respectively, through which coolant flows. Each cooling line arrangement 5 and 6 comprises a continuous cooling line 21.

[0052] One cooling line arrangement 5 is positioned next to the fan 4 on one side of a vertical plane 7 of the incubator 1, which extends through the incubation chamber 2 and in which a rotation axis 8 of the fan 4 is arranged. The other cooling line arrangement 6 is located next to the fan 4 on the other side of this vertical plane 7.

[0053] The cooling line arrangements 5 and 6 on both sides of the vertical plane 7 are mirror-symmetrical to each other. The vertical plane 7 forms a central plane that runs through the incubation chamber 2 of the incubator 1 and divides it into two subchambers.

[0054] The figures show that each cooling line arrangement 5 and 6 has its own coolant inlet 9 and its own coolant outlet 10. The coolant inlet 9 is connected to the coolant outlet 10 via the previously mentioned cooling line 21.

[0055] Coolant enters the cooling line 21 of the respective cooling line arrangement 5 and 6 via the respective coolant inlet 9, flows through the cooling line 21 and then exits the cooling line 21 again via the coolant outlet 10. The coolant inlet 9 of the respective cooling line arrangement 5, 6 is at a smaller distance from the fan 4, in particular from the aforementioned vertical plane 7, than the coolant outlet 10 of the cooling line arrangement 5, 6.

[0056] The figures illustrate that the coolant inlets 9 are arranged inside with respect to the fan 4, while the coolant outlets 10 are at a greater distance from the fan 4 and are thus arranged outside.

[0057] The air flow direction of the air flow generated by the fan 4 is illustrated by the arrows 100 around the fan 4 in Figure 1. The fan 4 is a radial fan that generates an air flow in the direction of the arrows 100, which is oriented radially with respect to its rotation axis 8.

[0058] The coolant inlets 9 and the coolant outlets 10 of the two cooling line arrangements 5 and 6 lie in a common horizontal plane, i.e. are arranged at the same height.

[0059] The fan 4 and the cooling line assemblies 5 and 6 are arranged on a common inner wall 11, namely on an inner rear wall, of the incubator 1. In an area 12 above the fan 4, line sections 13 of the cooling line assemblies 5 and 6 are arranged on the inner wall 11. In this area 12, the cooling line assemblies 5 and 6 are spaced less closely from the vertical plane 7 and also from the fan 4, and also from one another, than in an area 14 on the inner wall 11, which is arranged below the fan 4. This can be seen particularly clearly in Figure 1.

[0060] Line sections 13 of the cooling line arrangements 5 and 6 are arranged in meanders 15, wherein the meanders 15 are evenly spaced from one another within a cooling line arrangement 5, 6. Because the region 12 above the fan 4 is also occupied by the cooling line 21 and line sections 13 of the cooling line arrangements 5, 6, the meander density above the fan 4 is higher than in the region 14 below the fan 4.

[0061] A distance between the cooling line arrangements 5 and 6 above the fan 4 is at most as large as a smallest measurable distance between two meanders 15 within a cooling line arrangement 5 or 6.

[0062] The area 14 below the fan 4 has a width which corresponds at least to the diameter of the fan 4 and, in the exemplary embodiment shown, approximately two and a half times the diameter of the fan 4. This area 14 below the fan 4 is free of cooling line arrangements 5, 6, and therefore has neither meanders 15 nor line sections 13 or other parts of the cooling lines 21. However, this area 14 is laterally delimited by cooling line arrangements 5 and 6, namely by meanders 15 from line sections 13 of the cooling line 21 of the respective cooling line arrangement 5 and 6.

[0063] Part of the temperature control device 3 of the incubator 1 shown in the figures is also an electrical heating line 16, which is hidden in Figure 1 but shown in Figure 4. In Figure 4, the two cooling line assemblies 5 and 6 to the left and right of the fan 4 are hidden for the sake of clarity. Figure 5 shows the temperature control device 3 with both the heating line 16 and the two cooling line assemblies 5 and 6.

[0064] An incubator 1 which is only designed to cool the incubation chamber 2 can have a temperature control device 3 according to Figure 1 without a heating line 16.

[0065] An incubator 1 which is only designed to heat / warm the incubation chamber 2 can have a temperature control device 3 according to Figure 4 without heating line 16.

[0066] An incubator 1, which is designed for cooling and heating / warming the incubation chamber 2, has a temperature control device 3 according to Figure 5 with the heating line 16 and the two cooling line arrangements 5 and 6.

[0067] The electrical heating cable 16 is laid so that it is arranged on both sides of the fan 4.

[0068] The heating line 16 arranged on both sides of the fan 4 leaves the area 12 above the fan 4 free. Thus, there is no heating line 16 in the area 12 above the fan 4. However, the area 12 is laterally delimited by the heating line 16, with the heating line 16 running through the area 14 below the fan 4.

[0069] The heating cable 16 has a structure which is mirror-symmetrical to the vertical plane 7, as illustrated in Figure 4.

[0070] The fan 4 and the cooling line assemblies 5 and 6, as well as the heating line 16, are arranged on a common inner wall 11, namely on the inner rear wall of the incubator 1. The incubator 1 has a receiving space 20 in which the fan 4 and the two cooling line assemblies 5 and 6, as well as the heating line 16, are arranged. The receiving space 20 is separated from the incubation space 2 of the incubator 1 by a partition wall 18. According to Figure 3, the partition wall 18 has ventilation openings 19, via which the receiving space 20 is connected to the incubation space 2 of the incubator 1.

[0071] Through the ventilation openings 19, air can be drawn from the incubation chamber 2 into the receiving chamber 20 by means of the fan 4. The air drawn into the receiving chamber 20 can then be tempered as required by means of the temperature control device 3, i.e., by means of the cooling line arrangements 5 and 6 or the heating line 16.

[0072] The tempered air can then be evenly distributed in the incubation chamber 2 via air outlet openings 22 at the edge of the partition wall 18 or in the partition wall 18.
