Transport container with cooling device

The invention relates to transport containers with a cooling device, which has a chamber for receiving a coolant, at least a wall part of this chamber the Interior of the transport container is exposed in such a way that a heat transfer through this Y / and part of the chamber from the container contents including the air contained in the container to the coolant can take place ο

The invention is based on the object of making such a transport container more economical than before and in particular to be trained for minimal consumption of coolant.

A transport container according to the invention is identified by for this purpose in that the chamber for the coolant is mounted or formed on a wall of the transport container

309 8 3 0/0857

is and is essentially about the or the greatest Part of the length of the container extends, the chamber having one or more closable loading openings has on the ^ Lussseite of the container, through which the coolant can be filled in without the closed interior of the container with the outside air comes into contact.

The chamber or chambers for the coolant are preferably located completely inside the transport container, their openings being firmly and tightly connected to externally accessible openings in the connections of the transport container, so that the coolant is poured into the chamber or chambers can without opening the container _e

In cases where the coolant has the i ⁿ orm of blocks or pieces, the dimensions of the chamber or be ± -aMinern (if more than one is provided) is chosen such that a plurality of blocks can be arranged in series. In this way, as many blocks can be accommodated in the chamber as are required for the entire transport path of the container <i

In one embodiment of the invention, the chamber be stored or formed on the top of the transport container, whereby they are from a Sndwanduna of the

909830/0657

The container protrudes into its interior and this End wall then has openings through which the coolant from the outside of the container into the Chamber is insertable »

One side of the chamber can be opened from the top or the roof of the transport container "

The V / alls of the transport container are advantageously thermally insulated, while the wall or walls of the chamber i are thermally conductive.

If the coolant consists of several blocks of frozen material, small containers can be used for these Blocks are provided as well as brackets in the chamber, along which these containers are easily inserted in the chamber can be moved on.

For example, these small containers can be provided with wheels i which slide along on supports in the chamber.

Provision can also be made to couple the containers together so that they can be more easily withdrawn from the chamber .

909830/0657

The wheels can be on either side of the small container near their upper edge, and the side walls of the chambers are then along with it in the longitudinal direction extending guide channels provided in which these wheels slide, the arrangement in the Way takes place that the walls of the container and the chambers are close to one another.

The containers can be made from plastic.

The bottoms of the containers B _e can be provided with holes so that when the coolant from frozen CO ₂ is -Blöcken, the steam, which is heavier than air, can easily escape from the containers.

The bottom of the chambers can also be provided with holes.

When the chamber begins at one end wall of the transport container and behind an opening in this Wall is, this opening and the opening aligned with it at the end of the chamber can be separated Doors are provided so that the door at the end of the chamber is only accessible if the door of the corresponding one was previously used opening in the transport container has been opened.

909830/0657

If the containers are coupled to one another, means can be provided to attach a connecting container to the or to attach the doors at the end of the chamber, thereby preventing the containers from being transported during the transport of the Roll the transport container back and forth in the chamber; this fastening device is from outside the door or doors accessible.

It is also possible to arrange several chambers of this type next to one another in the transport container.

If longitudinal rails are attached to the top or roof of the transport container, on which the goods to be transported are hung, and these rails are arranged at a distance from one another there can be one or more cooling chambers in one or more spaces between the rails be provided.

According to the information given above, it is therefore possible to determine the number of containers filled with a coolant to be selected according to the time during which the transport container is expected to be on the move.

This allows the full number of containers to be inserted into the chamber so that they move in their entire length.

909830/0657

is set, but you only need to fill some of the containers with the coolant, according to the desired Regulations for the cooling of the transport container.

The arrangements described above are particularly suitable for transport containers with flat tops or flat roofs that are carried on trucks or freight cars or even in the holds of ships will. «

Further features of the invention emerge from the following description of an exemplary embodiment as well as from the drawings; in this shows:

Pig. 2 shows a perspective illustration of a coolant container, which is in the chamber;

Pig »3 is a side view of such a container;

Pig. Fig. 4 is a partial sectional and partial end view of that shown in Pig. 3 shown container;

909830/0657

Fig. 5 is an S _c hnitt by a part of the roof of the transport container and the chamber;

Fig. 6 is a side view of part of an end wall of the transport container in which the Opening can be seen through which the coolant container is pushed in and out be drawn, and

7 is a horizontal section along line 7-7 of FIG. 6th

As in F ^ g. 1 shows the transport container with a roof 10, end walls 11 and 12, side walls 13 and 14, a floor 15 and a sealed door 6 provided; All these parts are made of heat-insulating material, several rails 16 are attached to brackets 17 (see Fig. Fig. 5) attached to the roof structure and extend at a distance from one another along the transport container. Several sliders 9t hang on each rail 16 the rollers 8 of which run on flanges of the rails 16; ^

each slider is also provided with a hook 7 on which the goods to be cooled can be hung. Furthermore, on part 18 of the roof structure between adjacent rails 16 is one in Fig. 5 generally with

19 designated chamber attached, which consists of aluminum sheet, which is in the form of a trough with a bottom surface

20 and side walls 21 bent upwards

have a greater distance from each other; to your 909830/0657

Outer sides are friction strips # n 22 made of mild steel appropriate. Projections 23 in the side walls form guides 24 which extend along the entire chamber, and the upper edge strips 25 of these projections are attached to Y / inkelprofile 26, which in turn are connected to the roof structure.

As can be seen from Fig. 5, the height of the roof can be different, so that the angular T _e ile 26 have different heights.

One end of the chamber 19 is located opposite an opening 27 in the end wall 11 of the transport container. A door 28 is attached to this end wall by means of hinges (not shown in the drawing), which with Sealing strip 29 is provided. The edges of the door and the edges of the opening 27 are wedge-shaped *, as best made of pie ;. 7 can be seen. Furthermore, by means of Hinges 31 on both sides of the opening 27 two door parts 32 (Fig. 7) attached, with which the open The end of the chamber 19 is closed. The chamber is provided with lugs 33, possibly in one piece, which fit tightly and firmly against the sides of the openings 27 in the end wall 11.

Several containers can be placed in the chamber 909830/0657

be inserted, as most clearly in the Pig. Is .2, 3 and 4, and these containers are conveniently made by _a H rz connected glass fibers. The side walls 34 of each container extend divergingly from the bottom surface 35 upwards; at the upper end of the inside of these walls is a mild steel strip 36 to which a plurality of outwardly protruding horizontal axles 37 are attached, which pass through bores in the side walls 34 and on which rollers 38 are mounted so that they are on the lower surface of the guides 24 can roll along. On the outer surface of the side walls 34 are, as best shown in FIG. 2 can be seen, resin-bonded plywood strips 46 glued on. The bottom surface 35 can be provided with a number of holes (not shown). A hook-shaped part 40 is attached to one end wall 39 of each container, while the other end wall 41 is provided with an eyelet 42 so that successive containers can be coupled to one another when pushed through the opening 27.

As can be seen from FIGS. 6 and 7, the sections 43 of the hinges 30 are attached to the door part 32 in such a way that that they protrude beyond the edges of these door parts and thereby overlap, and also have slots 44 through which the eyelet 42 of a final container

909830/0657

can protrude and then be held with a locking pin 45.

The design and arrangement of the containers and the chambers that hold them, as well as the transport container is based on the following considerations:

If the B.t.u. value (calorie value of the latent and

the self-heat) and the boiling temperature of solid C (^ are known, the rate of evaporation of CO is determined by tightly enclosing a block of solid GOp in a small container made of e.g. wood, aluminum or glass fiber reinforced plastic or any other material whose heat transfer is known ₂ to the extent that the material of this container absorbs the heat from CO _2. This in turn depends on the temperature difference between the required temperature and the room temperature.

When the small container is placed in a transport container, in the frozen meat or the like Products are to be transported, effective cooling can be achieved if only the following Information is known:

909830/0657

1. Thermal heat dissipation of the transport container;

2. the temperature of the product during loading;

3. the desired temperature of the product at the end of the trip;

4ο the average temperature of the area during the respective transport time, so that the temperature difference can be estimated can.

The heat is transferred through the walls of the small container to the chamber in which it is is arranged and which acts like a cold plate. Small holes are drilled into the bottom of the chamber, so that the C0 ~ 2 gases through this into the usable space of the transport container, which has two further advantages:

a) the additional value of the inherent heat of the cold gas in addition to the latent one Warmth;

b) the retarding effects of carbon dioxide.

The construction of the small _{CO 2} container is based on calculations that assume the largest volume that a rectangular block of solid CO ₂ of 25 lb (11.35 kg) can occupy; the dimensions of the inner lining

909830/0857

of the container are then chosen so that the block fits exactly and only minimal air gaps available. The liner is insulated by insulation made of solid foam, then with a provided on the outer wall, and a removable cover (not necessarily gas-tight) is attached to it, to completely enclose the COp block. Afterward the coefficients are calculated and give the heat dissipation through the walls times per hour Temperature difference.

The heat is then transferred to the continuous cooling transition, which, if it is made of aluminum, a Y / ärmeübertragungskoeffiezienten 1423 Btu / hr. / Inch of thickness / ft / ° F (176.5 kcal / mh ⁰ C) would have. Therefore, the main cooling duct would absorb all of the heat transferred from the small OOg container and distribute it over its entire surface, with the extent of the transfer and sublimation of the solid CO _{2 being} controlled by the small container made of one material that has a higher resistance to heat transfer.
