Definitions

  • the present invention relates to a temperature controllable tank container of the type comprising a tank mounted between a pair of end frames, and an insulating shell extending round the tank and substantially enclosing tbe tank, longitudinally disposed, elongated ducts being provided between the insulating shell and the tank wall for carrying a heat transfer medium in one direction and for returning the heat transfer medium in the other direction along the tank, and communicating means at one end of the tank to connect the duct carrying the heat transfer medium in one direction with the duct carrying the heat transfer medium in the other direction, the ducts at the other end of the tank terminating in a respective inlet and outlet for connecting to a heating or cooling means.
  • the invention relates to a refrigerated tank container, although needless to say, it is not limited to a refrigerated tank container.
  • Refrigerated tank containers are known, British Patent Specification No. 2,049,628 discloses a refrigerated tank container which comprises a tank mounted within a framework, the framework comprises end frames joined by longitudinal top and bottom side members. The walls of the framework are completely closed by insulating panels, which define with the tank a cavity for the circulation of a cooling medium for cooling the tank and its contents.
  • a horizontal partition wall extending between the side and end walls of the framework and the tank forms an upper and lower chamber.
  • An inlet and outlet is provided in one end wall to respective chambers, so that a cooling medium can flow from the inlet over the lower portion of the tank in the lower chamber and return in the upper chamber to the outlet.
  • Such tank containers in general, are adapted to be connected into an external refrigerating unit or into a refrigerating system of a ship, road tanker or the like, from which the cooling medium is derived.
  • Such insulating tanks suffer from a considerable number of disadvantages.
  • the chambers for the cooling medium are of relatively large volume, and thereby require a considerable volume of cooling medium.
  • Air is generally used as the cooling medium, and thus a refrigerating unit for cooling or chilling the air must be of a relatively large capacity to handle the volume of air required.
  • a further disadvantage of known refrigerated tank containers is that the insulating material can be relatively easily damaged or punctured. By virtue of the fact that the insulating panels are formed in the walls of the framework, they are prone to damage as a result of being knocked against another container or other obstacle or obstruction.
  • a further disadvantage of these known tank containers is that because of the large volume of air required, they tend to be relatively inefficient.
  • a cooling coil for carrying a liquid refrigerant is wound round the tank.
  • heat insulating material is provided around the cooling coils.
  • the temperature controllable tank container according to the invention overcomes the problems of known tank containers by virtue of the fact that two longitudinally disposed, elongated side ducts are provided for carrying the heat transfer medium in one direction, one of the side ducts being provided on one side of the tank and the other side duct being provided on the opposite side of the tank, the side ducts being provided in substantially similar locations on their respective sides of the tank, and the insulating shell abuts a lower portion of the tank wall between the side ducts.
  • the advantages of the tank container according to the invention are many.
  • a particularly important advantage of the tank container is that it very effectively optimises between the amount of heat transferred to or from the tank and the size of the tank container.
  • the tank container according to the invention can be provided as a relatively slim tank, and at the same time relatively high heat transfer to or from the tank is achieved.
  • the quantity of heat transfer medium required is retained to a minimum, while at the same time good heat transfer characteristics are achieved.
  • the tank container of a relatively high efficiency where the tank including the insulating shell is provided internally of the outer dimensions of the end frames, the insulating shell is less prone to damage which could in many instances lead to leakage of the heat transfer medium.
  • a further advantage of the invention is the fact that because of the construction of the tank container, a relatively inexpensive tank container can be produced which is also relatively easy to manufacture.
  • the duct for carrying the heat transfer medium in the other direction is provided by at least one longitudinally disposed, elongated top duct extending along the top of the tank.
  • the advantage of this feature of the invention is that it further increases the efficiency of the tank container, and by virtue of the fact that the duct is provided on the top of the tank, the insulating shell at this point is less prone to damage which could result in leaks from the top duct.
  • the side ducts are arranged so that a longitudinal centre line of each duct co-incides with a horizontal plane of the tank which extends through a longitudinal centre line of the tank.
  • the advantage of this feature of the invention is the fact that by substantially centrally aligning the side ducts maximum efficiency of heat transfer is achieved.
  • each side duct extends over at least 10% of the outer circumference of the transverse cross section of the tank.
  • the advantage of this feature of the invention is that it provides a tank container with relatively good heat transfer efficiency.
  • each side duct is of arcuate cross section.
  • the advantage of this feature of the invention is that it provides for a relatively slim construction of tank and accordingly tank container, while it also reduces the amount of heat transfer medium required to a minimum.
  • a pair of top ducts are provided, the top ducts being equi-spaced on either side of a central vertical plane of the tank, each top duct extending over at least 2% of the outer circumference of the transverse cross section of the tank.
  • the tank is of cylindrical construction having an elongated cylindrical portion closed by end caps, the insulating shell being of partly cylindrical construction and extends around the tank and abuts portions of the tank, and a top portion of the insulating shell extends upwardly to form each top duct.
  • the advantage of this feature of the invention is that it provides a relatively slim construction of tank, and in turn a relatively uncumbersome tank container. Furthermore, because the insulating shell substantially follows the contour of the tank, the insulating shell, in general, falls well within the outer dimensions of the end frames and accordingly is less prone to damage which could result in leakage of the heat transfer medium.
  • the insulating shell comprises a heat insulating material disposed between an outer skin formed of sheet material and an inner skin formed by portion of the tank wall and plate members which form the ducts.
  • the advantage of this feature of the invention is that it provides a relatively efficient and inexpensive construction of tank container. It also leads to a relatively easily manufactured tank container.
  • the insulating shell is closed at one end by an end cap spaced apart from the end cap of the tank to form the communicating means, the end cap being of a heat insulating material.
  • This feature of the invention also leads to a relatively efficient construction of tank container, and it provides a tank container which is easily manufactured and relatively inexpensive.
  • a cooling means provided by a refrigerating unit to cool the heat transfer medium is mounted in the end frame adjacent the inlet and outlet of the ducts, the refrigerating unit being connected to the inlet and outlet for circulation of the heat transfer medium through the side and top ducts, means to circulate the heat transfer medium being provided, so that the heat transfer medium is delivered from the refrigerating unit to the side ducts and returned to the refrigerating unit through each top duct.
  • the advantage of this feature of the invention is that it provides a self contained tank container, and accordingly provides a relatively efficient tank container which is relatively easily constructed, relatively inexpensive and convenient to use.

It will also be appreciated in certain cases that the heat exchanging plates may extend between the tank wall and the plate members 49 and 57 of the side and top ducts respectively.
  • the tank may be provided without a refrigerating unit, and the tank would thus be suitable for connecting into an independent refrigerating system, such as, for example, a refrigerating system provided on board a ship, or a refrigerating system provided on a truck or rail car or the like.
  • an independent refrigerating system such as, for example, a refrigerating system provided on board a ship, or a refrigerating system provided on a truck or rail car or the like.
  • appropriately constructed inlets and outlets would be provided to the side ducts 45 and top ducts 46 , or in the end cap of the insulating shell adjacent the front end frame for connecting to such an independent refrigerating system.
  • a front end frame of any other shape or construction could be provided. Indeed, where a different refrigerating unit of a different shape or construction is provided, it is envisaged that a frame of appropriate shape and construction would be used to house the refrigerating unit.
  • the front end frame could be constructed similarly to the rear end frame, and in which case, a single inlet and outlet would be provided for the cooling medium. This inlet and outlet would be connected to the side and top ducts 45 and 46 respectively.
  • end frames have been described as being constructed to ISO standard and that the entire tank container has been constructed to ISO standards, it could be constructed to any other standards. Indeed, it is envisaged that the tank container could be constructed so that it would be suitable for mounting on a swap body truck.
  • the tank container has been described as comprising a chamber for the chilled air in front and end thereof, the chambers, in certain cases, may be dispensed with.
  • the tank has been described as comprising dished ends which are of convex construction, in certain cases, it is envisaged that the tank may be provided with dished ends which would be of concave construction or in certain cases flat ends.
  • the insulating shell may be substantially cylindrical or in the case of a tank of other construction to substantially follow the cross sectional profile of the tank, this is not necessary.
  • the outer shell could be of any other shape or construction or any other cross section, for example, rectangular cross section, square cross section, hexagonal cross section.
  • any other suitable heat transfer medium could be provided, for example, a liquid heat transfer medium could be used such as water or any other gas.
  • the heat transfer medium could be circulated in the reverse direction, for example, the heat transfer means could be arranged to flow along the top ducts and return along the side ducts.
  • the tank container has been described as being a refrigerated insulated tank container, it could be provided as a heated insulated tank container, in which case, the heat transfer medium would be heated instead of cooled, and the heat transfer medium could be heated by a suitable heating means mounted on the tank container, for example in place of the refrigerating unit.
  • the tank container could be connected to an independent heating system for heating the heat transfer medium.
