Definitions
- Insulated container with fillable cooling module Insulated container with fillable cooling module
- the invention relates to an insulated container with a cooling module and a method for filling a cooling module for an insulated container.
- Containers with a thermally insulating wall are therefore used for the transport and storage of perishable goods, especially food.
- the insulated containers are usually additionally cooled in order to be able to maintain a low temperature inside the insulated container for a longer period of time.
- Solid or liquid carbon dioxide or liquid nitrogen is used to cool insulated containers.
- the liquid nitrogen stored in a vacuum-insulated container under a refrigerated vehicle is sprayed in gaseous form in the cargo area, where it extracts heat energy from the cargo area air in order to cool the temperature-sensitive substances in it (Gas A Communication, issue 51, page 8, Messer Griesheim GmbH, 1996).
- Cold storage plates which are filled with a liquid, a so-called “eutectic liquid” or cooling brine, are also used for cooling purposes.
- the connecting piece for filling is usually arranged on the front of the cooling module, so that the filling is only possible after opening the door of the insulating container.
- This has the disadvantage that the cold escapes from the insulated container into the usually warmer, surrounding space during each filling process. So that is Every filling process is associated with a loss of cold, which can affect the temperature-sensitive substances in the insulated container.
- the object of the invention is therefore to provide an insulating container with a cooling module, with which the filling process of the cooling module with a cooling medium can be carried out safely and technically in a simple manner without opening a door of the insulating container. Furthermore, a method for filling a cooling module in an insulating container is to be provided, with which the cooling medium can be introduced into the cooling module as efficiently and safely as possible without opening a door of the insulating container.
- an insulating container with a cooling module which has a filling opening in the region of the upper insulating container wall, which is connected to a supply opening of the cooling module in order to supply a cooling medium to the cooling module, and the cooling module has at least one discharge opening, from which cooling medium in can escape the interior of the container to cool it.
- insulation container is to be understood as all conceivable types of at least partially closed containers, for example containers,
- Cabinets, trolleys or trolleys that have a thermally insulating wall and in which temperature-sensitive products can be stored or transported while maintaining a certain temperature for a certain period of time.
- cooling medium here means in particular a cryogenic liquefied gas or gas mixture which is present as a gas at normal room temperature (approx. 23 ° C.) and at normal pressure (approx. 1 bar), for example nitrogen, carbon dioxide or air, and which is in the liquid, supercritical or solid state at the appropriate temperature and pressure, the term “solid” state also including a lumpy, granular or snow-like shape.
- cryogenic liquid nitrogen is used as the cooling medium, the cryogenic nitrogen being stored essentially in liquid form in the cooling module, evaporating over time and escaping through the discharge opening in the cooling module as a gaseous substance into the interior of the container in order to cool it.
- the filling opening can be closed with the aid of closure means which do not protrude beyond the surface of the upper insulating container wall.
- a permanent ring magnet for example, can be used as a closure of the filling opening, in the middle of which
- Insulating material is arranged so that it extends into the wall duct of the filling opening and seals there, the ring magnet being held, for example, by a steel disk arranged around the filling opening. In this way, cold losses can be largely avoided.
- the closure means of the filling opening interact with means of a device for supplying the cooling medium to the cooling module in order to couple the device for supplying the cooling medium to the insulating container or the cooling module.
- the device for supplying the cooling medium has magnetic or electromagnetic means in the area of its end which can be connected to the filling opening, which cooperate with corresponding magnetizable or magnetic means in the area of the filling opening of the insulating container in order to provide the device for supplying the cooling medium to the insulating container or the To couple cooling module, preferably the coupling through the interaction of a
- Electromagnet which is arranged in the device for supplying the cooling medium in the region of its end which can be connected to the filling opening, and an annular steel disk which is arranged in the region of the filling opening.
- This steel disk can advantageously be incorporated into the insulating material of the thermally insulating wall of the insulating container in such a way that no parts protrude beyond the surface of the upper insulating container wall.
- the device for supplying the cooling medium is assigned an injection tube for the cooling medium, around which injection tube there is one arranged electromagnetic coil and a steel disc is arranged around the filling opening.
- a magnetic attraction acts on the injection tube in relation to the insulating container or the cooling module, as a result of which the device for supplying the cooling medium is coupled to the cooling module.
- the steel disk is made of a material that can be magnetized or magnetized, for example a chrome or nickel steel.
- the injection tube is advantageously made of a metallic material, for example copper or stainless steel, and the outflow opening for the cooling medium in the injection tube is selected in accordance with the desired volume flow. All conceivable types of are here under the term "injection pipe"
- the device for supplying the cooling medium to the cooling module has a supply line which is connected to a source of cooling medium under pressure.
- the device for supplying the cooling medium is assigned a device for controlling the filling quantity, which has a shut-off device and a timer that is operatively connected to the shut-off device, with the aid of which the duration of the supply of
- Cooling medium is controlled in the cooling module to supply different amounts of cooling medium to the cooling module.
- a valve or a slide is used as the shut-off device.
- an electromagnet in the device for supplying the cooling medium for example an electromagnetic coil arranged around the injection pipe and one around the injection pipe
- the device for supplying the cooling medium is held when power is supplied to the coil and can be released by interrupting the power at any time, if necessary automatically after the filling process.
- the cooling module is detachably connected to the insulating container and has devices which are in operative connection with corresponding devices of the insulating container and an insertion and storage to enable the cooling module in the insulating container, so that the cooling medium can also be supplied to the cooling module outside the insulating container.
- the cooling module consists of stainless steel and has thermal vacuum insulation. The vacuum of this
- Vacuum insulation is preferably less than 20 mbar, particularly preferably 0.01 to 1 mbar.
- a gas filling of the interior with carbon dioxide or argon can be used at the vacuum pressure mentioned.
- the height of the cooling module is 50 to 200 mm, preferably 60 to 100 mm.
- At least one cooling module and at least one cold storage plate are arranged adjacent in the insulating container.
- This has the advantage that part of the cooling capacity of the cooling medium can initially be absorbed by the cold storage plate. This advantageously avoids initial hypothermia of the material to be cooled. The cold of the cold storage plate is released again later, which significantly extends the cooling time.
- the cold storage plate thus acts as a cold buffer and cold storage.
- According to the cold storage plate is arranged below the cooling module in the insulating container.
- the cold storage plate thus advantageously acts as a buffer against an excessive cooling effect on the underside of the cooling module.
- a eutectic liquid as the liquid in the cold storage plate.
- the eutectic liquid has a freezing temperature of 0 to -40 ° C, particularly preferably of about -2 to -4 ° C.
- the cooling module has a discharge opening from which essentially gaseous cooling medium can escape into the interior of the container, the discharge opening of the cooling module preferably being the supply opening at the same time.
- This opening can advantageously be provided with a flap, which is kept closed by its own mass due to gravity or with the aid of a suitable locking mechanism and can only be opened at a certain pressure inside the cooling module by the gaseous cooling medium which forms.
- the absorption volume of the cooling module of cooling medium is up to 20,000 g, preferably 500 g to 15,000 g. Different amounts of cooling medium can advantageously be filled into the cooling module.
- the amount of cooling medium to be filled is dependent on a large number of parameters, for example depending on the outside temperature, the temperature to be maintained in the insulating container, the starting temperature of the insulating container, the type of product in the insulating container, the duration of cooling, the mode of transport and / or the type and Insulated container size. For example, very large quantities are required for ship's tanks and only a relatively small amount (up to a few grams) of cooling medium is required for insulating containers for vaccines or for certain trolleys.
- the substantially vertical wall of the insulating container is formed on the inner surface thereof, for example by a certain lamellar structure of the surface, that gaseous cooling medium which arises in the upper region of the insulating container better falls or flows into the lower region of the insulating container. This can advantageously improve the temperature distribution within the insulating container.
- the object on which the invention is based is further achieved by a method for filling a cooling module in an insulating container with a cooling medium, in which the cooling medium is fed to the cooling module from above through a filling opening in the upper insulating container wall and a supply opening of the cooling module connected therewith, whereby Coolant from the
- Cooling module can escape into the interior of the container via at least one discharge opening in order to cool it.
- a device for supplying the cooling medium during the filling process is coupled by magnetic force to the insulating container or to the cooling module, preferably the magnetic force using an electromagnet in the region of the end of the device for supplying the cooling medium which can be connected to the filling opening and is exercised with the help of a steel disc arranged in the area of the filling opening.
- an amount of 200 to 2000 g, particularly preferably 800 to 1200 g, of cooling medium evaporates within one hour in order to cool the interior of the insulating container.
- the duration of the supply of the cooling medium into the cooling module is controlled according to the invention by a control device assigned to the filling device, in order to supply the cooling module with different amounts of cooling medium and thus to set a desired cold preservation of the substances within the insulating container.
- a control device assigned to the filling device By controlling the filling time, at a given pressure of the cooling medium during the filling process, different amounts of the cooling medium can be fed to the cooling module in order to set a time-desired cold preservation of the substances within the insulating container.
- Cryogenic, liquefied nitrogen is preferably used as the cooling medium.
- the insulating container according to the invention and the method are advantageously used for the temporary cold preservation of temperature-sensitive substances, preferably for cooling food.
- products can be pre-cooled and / or frozen using the device and the method according to the invention. This enables an advantageous use in the storage of fresh products, for protection against oxidation and to extend the shelf life of the fresh goods.
