Definitions
- the present invention relates to a thermally insulated transport container according to the preamble of patent claim 1 .
- Deep-freeze transport containers that are highly insulating and equipped with a cold store are already known which are suitable for solving this problem, for example the transport container for cooling frozen goods known from EP 2 041 502 B1.
- DE 10 2007 008 351 A1 discloses a self-cooling transport container which, inside the cooling chamber, is equipped with a revolver-like rotatable magazine with a large number of refrigerated goods receptacles arranged in a ring.
- a tubular access channel element is provided stationary in the transport container eccentrically over the ring of the individual refrigerated goods receptacles.
- the object of the present invention is to improve a thermally insulated transport container of this type in such a way that even when transporting a large number of refrigerated goods containers that are removed at intervals from one another, the maximum cold holding time is not severely shortened.
- thermally insulated transport container with the features of claim 1.
- a thermally insulated transport container is provided with an outer housing surrounding an outer insulating chamber, an inner housing disposed within the outer housing and surrounding an inner refrigerant chamber, and a refrigerated space located within the inner housing, the refrigerated space being connected to a tubular access duct member , whose tube interior opens into the refrigerated space and which can be closed by means of a closure insert, and wherein the refrigerated space has a plurality of refrigerated goods chambers for accommodating refrigerated goods.
- the invention provides that the refrigerated space has a central refrigerated goods chamber surrounded by a plurality of decentralized refrigerated goods chambers, that the tubular access channel element is arranged centrally in the outer housing and in the inner housing and is aligned with the central refrigerated goods chamber () and that the decentralized refrigerated goods chambers each have a transfer gate with the central refrigerated goods chamber in connection or can be brought into connection.
- a container for refrigerated goods is always removed from the central chamber for refrigerated goods located in the axial center of the refrigerator compartment and thus from the central center of the inner housing surrounded by the refrigerant chamber. If warmer ambient air penetrates into the central refrigerated goods chamber during a removal process, a symmetrical thermal load occurs on the refrigerant forming a cold store and provided in the refrigerant chamber, as a result of which the storage capacity of the cold store is only slightly loaded.
- the solution according to the invention does not require a complicated turning mechanism, because when the central refrigerated goods chamber is empty, a refrigerated goods container can slip from one of the decentralized refrigerated goods chambers through the associated transfer gate into the central refrigerated goods chamber by slightly tilting the transport container.
- the transport container constructed according to the invention also has the advantage that the central, tubular access channel element enables essentially unobstructed access to the cooling space even when the transport container is being cleaned. Reliable and uncomplicated cleaning of the cold room is possible, particularly in the case of liquids that have leaked out in the cold room, especially when the surfaces in the cold room are formed by a smooth wall, for example made of stainless steel.
- a tubular ring slide device that can be rotated about a central axis and has at least one transfer opening in its peripheral wall, which can be brought into overlap with a respective transfer gate by rotating the ring slide arrangement, whereby a passage from a decentralized refrigerated goods chamber assigned to the transfer gate to the central refrigerated goods chamber is formed.
- a ring slide device enables the targeted selection of a decentralized refrigerated goods chamber by bringing the transfer opening of the ring slide device into alignment with the transfer gate of a selected decentralized refrigerated goods chamber, as a result of which only one refrigerated goods container from this decentralized refrigerated goods chamber can enter the central refrigerated goods chamber.
- the transfer gates of all other decentralized refrigerated goods chambers are closed by the wall of the ring slide device, so that no warmer ambient air entering the central refrigerated goods chamber due to the removal process can penetrate into these closed decentralized refrigerated goods chambers.
- the ring slide device can be removed simply by pulling it out of the interior of the tubular access channel member. This facilitates both cleaning of the interior and the central and decentralized refrigerated goods chambers and also enables rapid cooling of the cold store.
- the central ring slide device can preferably be inserted into the central tubular access channel element so that it can be removed in the axial direction. This makes it possible to remove the entire annular slide device, for example for cleaning purposes, which also facilitates access to the cooling chamber for cleaning purposes.
- the ring slide device reaches into the interior of the tubular access channel element with an end pointing away from the bottom of the central refrigerated goods chamber.
- no air from the access channel element is introduced into the decentralized refrigerated goods chambers and also a convection-related air exchange between the interior of the access duct element and the decentralized refrigerated goods chambers, especially if the section of the annular slide device that engages into the access channel element is additionally sealed against the inner circumference of the tubular access channel element by means of a shaft seal is thus reliably prevented.
- an embodiment of the invention that can be combined with other embodiments is particularly advantageous, in which the ring slide element is provided with coupling means on its end face pointing away from the bottom of the central refrigerated goods chamber, which are designed for non-rotatable coupling with counter-coupling means provided on an end face of a tubular actuating element, wherein the tubular actuating member is insertable into the tubular access channel member.
- the actuating element can be removed from the tubular access channel element when not in use and thus cannot form a thermal bridge if the access channel element is closed with a sealing insert, for example with an insulating plug.
- the outer housing and the inner housing as well as the central refrigerated goods chamber and the tubular access channel element have a circular-cylindrical shape and are coaxial arranged to one another, the decentralized refrigerated goods chambers being arranged in a star shape around the central refrigerated goods chamber.
- This circularly symmetrical design causes a particularly effective and uniform insulation of the refrigerated goods chambers.
- the decentralized refrigerated goods chambers are formed by refrigerated goods niches that extend radially outwards from the central refrigerated goods chamber.
- the annular slide device has two tubular annular slide elements which are arranged coaxially within one another and each have at least one transfer opening in their peripheral wall and which can be rotated relative to one another.
- This coaxial arrangement of two annular slide elements that can be rotated relative to one another, each with at least one transfer opening makes it possible to bring a transfer opening of the inner annular slide element and a transfer opening of the outer annular slide element into alignment with one another in order to form a common transfer opening of the annular slide device, which is then connected to a transfer gate of a decentralized refrigerated goods chamber in Coverage can be brought to open this decentralized refrigerated goods chamber to the central refrigerated goods chamber.
- the outer housing has a cup-like outer housing body which is closed by means of an outer cover wall and the tubular access channel element is connected to the outer cover wall.
- the inner housing main body connected to the tubular access channel element is inserted into the outer housing main body and its outer wall, together with the wall of the tubular access channel element, delimits the wall of the outer Housing body and the outer cover wall an interior space of the outer housing body.
- This outer interior space of the outer housing base body is evacuated and therefore particularly good thermal insulation.
- the outer interior space is preferably filled with a poorly heat-conducting mechanical support means in order to be able to more effectively support the pressure forces of the ambient air pressure acting on the wall of the outer housing base body in the evacuated vacuum or negative pressure state.
- a poorly heat-conducting mechanical support means in order to be able to more effectively support the pressure forces of the ambient air pressure acting on the wall of the outer housing base body in the evacuated vacuum or negative pressure state.
- the free paths of individual gas molecules that may still be present in the interior in the event of a high vacuum are restricted by the proppant, in particular pyrogenic silica as a proppant, so that a high degree of insulation is achieved even in this case.
- a likewise preferred embodiment of the invention is characterized in that the inner housing has a cup-like inner housing base body which is closed by means of an inner cover wall and that the tubular access channel element is connected to the inner cover wall.
- the inner housing base forms a cooling insert, the wall of which surrounds the cooling space and is connected to the tubular access channel element, the interior of which opens into the cooling space.
- the inner space of the inner housing base body is filled with a refrigerant or cooling elements filled with refrigerant are inserted into this inner inner space.
- the cooling elements provided with the refrigerant can be used in the inner interior during assembly.
- Different housing base body elements of the inner housing base body are preferably provided and can be combined with one another, which define inner interior spaces of different sizes, so that different numbers or different sized cooling elements can be accommodated by the inner interior space.
- the cooling capacity can be adjusted to the needs during assembly and it can be easily and different transport containers with different cooling capacities can be manufactured in a cost-effective manner in a modular system.

- the upper end of the tubular inner annular slide element 66' which projects out of the outer annular slide element 60' and faces away from the central cooling chamber 40, is also provided with an actuating element 66'' which projects radially outwards and forms a lever with which the inner annular slide element 66' can be rotated manually in both directions within the outer annular slide element 60' and relative thereto about the central axis X, as symbolically represented by the double arrow B in Fig. 8.
- the removal slide 9 Centrally in the tubular inner annular slide element 66' and coaxially thereto is a cylindrical removal slide 9, displaceable in the direction of the central axis X, but non-rotatable and preferably sealingly inserted at the periphery.
- the removal slide 9 has an upper shaft section 90 with a closed cross-section, on the upper end of which, protruding from the ring slide device 6', an actuating handle 91 is attached.
- free end 93 of the shaft section 90 of the removal slide 9 is provided with a lateral transfer opening 96 tubular section 92 is provided which has a receiving and transport space 97 for a refrigerated goods container 70, 71, 72, 73, 74, 75, 76 trained.
- a refrigerated goods container accommodated therein can thus be removed from the refrigerated space or introduced into the refrigerated space by means of the removal slide 9 .
- the wall 95 of this tubular section 92 is therefore interrupted by the transfer opening 96, which has the same dimensions in the circumferential direction (opening angle) as the transfer openings 65 and 67 of the two annular slide elements 60', 66'.
- the axial extent of the transfer opening 96 in the wall 95 of the removal slide 9 is preferably adapted to the axial length of the refrigerated goods containers 70, 71, 72, 73, 74, 75, 76, i.e. slightly larger than these, so that only one refrigerated goods container can be placed in the Pick-up and transport room 97 can be included.
- Such a removal slide 9 is designed for the removal of an individual refrigerated goods container.
- the transfer openings 96 and 67 of the removal slide 9 and the inner ring slide element 66 are always aligned with one another in the circumferential direction as soon as the removal slide is inserted far enough into the inner ring slide element 66.
- Removal slides with an axially longer transfer opening 96 for higher refrigerated goods containers or, if several refrigerated goods containers are accommodated one above the other in the decentralized refrigerated goods chambers 41, 42, 43, 44, 45, 46, can also be provided for the removal of several refrigerated goods containers. If several refrigerated goods containers are accommodated one above the other in a decentralized refrigerated goods chamber, a removal slide can also be provided in which the axial extent of the transfer opening 96 essentially corresponds to the axial extent of the transfer gates 4T, 42', 43', 44', 45' , 46' and which thus forms a loading slide for the cooling chambers.
- the interchangeability of the removal slide 9 increases the flexibility of use of the transport container according to the invention.
- both the shank section 90 of the removal slide 9 and the annular slide elements 60', 66' are preferably made of a material that conducts heat only very poorly or not at all, such as stainless steel, titanium or a plastic (eg Teflon).
- the outer annular slide element 60' is first rotated again relative to the inner annular slide element 66' in order to close the access to the decentralized cooling space again and allow cold to escape impede.
- the decentralized cooling rooms are filled in the opposite way, also using gravity.
