Definitions

  • the present invention relates to a system for temperature-controlled storage and/or transport of a product, for example of a perishable food product or a medicament that has to be kept at ambient or low temperature or in a frozen condition.
  • the present invention further relates to a method for temperature-controlled storage and/or transport of a product.
  • products can be transported in a temperature-controlled cargo space of a vehicle.
  • temperature-control is, however, relatively energy consuming and expensive since the entire cargo space that has to be kept at a certain temperature.
  • temperature-control is inefficient for delivery to individual customers, in particular in an urban environment, since such delivery requires the cargo space doors to be opened many times.
  • the system of FR 2 689 222 A1 does not provide active cooling of the container content during transport. The time during which products can be kept cool is thus limited. Furthermore, the system of FR 2 689 222 A1 requires engagement of each container to a stationary cooling device with an evaporator. This makes the system relatively complex and expensive and unsuitable for delivery of a relatively small number of products to several customers, as is typically the case in urban delivery to consumers.
  • the inventors have found a novel system for temperature-controlled storage and/or transport of a product comprising at least one storage rack comprising a hollow frame formed by a plurality of hollow tube elements of a heat-conductive material, such as e.g. a metal, that define a fluid flow path for a heat-transfer fluid.
  • the fluid flow path in the hollow frame has an inlet and an outlet that are connectable to the outlet and inlet, respectively, of a temperature-regulating device so that cooled or heated heat-transfer fluid from the temperature-regulating device can circulate through the hollow frame of the storage rack.
  • the system also comprises a plurality of thermally-insulated product containers, each comprising a product receiving chamber for the product(s) to be stored or transported under temperature-controlled conditions, wherein the product receiving chamber is at least partly lined with a heat-conductive plate, which plate is in direct heat-conductive contact with the hollow frame of the storage rack through which the heat-transfer fluid circulates when the product container is placed on the rack for storage or transport.
  • the hollow frame of the storage rack serves several purposes. It provides both a support for the product containers and a structure giving shape and strength to the support rack, and it transfers heat or cold to the product containers via the heat-transfer fluid flowing through it to control the temperature in the product containers supported on it.
  • the temperature-controlled storage and/or transport system advantageously provides a system that can be used without separate items for passive cooling or heating, such as ice packs, ice blocks, or dry ice, in the product containers.
  • the system according to the invention is particularly suitable for temperature-controlled transport of products in a vehicle with a cargo space, such as for example a cargo van or a delivery truck, as typically used for urban delivery of products to consumers.
  • the storage rack is relatively light-weight since it has a frame formed by hollow tube elements and is particularly suitable to be provided with wheels to be wheeled in and out the cargo space of such vehicle.
  • the system is such that the temperature-regulating device can be located at a certain distance of the storage rack, preferably outside the space wherein the storage rack carrying product containers is located, such as the cargo space of a vehicle, so that any heat or cold generated by the temperature-regulating device is not released in the same space as the products to be kept at a controlled temperature are present. Thus, energy consumption is minimized.
  • the present invention provides a benefit over existing storage and transportation systems in that the containers themselves are relatively simple. Except for the heat-conductive plate lining the product receiving chamber, the product containers do not need to comprise or contain any other means for passive or active cooling (or heating), since the hollow frame of the storage rack serve the purpose of transferring cold or heat to the containers. Thus, the containers can be relatively light and its volume can be used more efficiently for storing and/or transporting products.
  • the invention provides a method for temperature-controlled storage and/or transport of a product, using a system as disclosed herein, the method comprising the steps of:
  • the method is user-friendly, requiring relatively little handling.
  • the method only requires placing the product containers filled with product on the storage rack and fluidly connecting the storage rack to the temperature-regulating device to effect circulation of heat-transfer fluid with a set temperature through the hollow frame of the storage rack.
  • all containers placed on the hollow frame of the rack are temperature-controlled.
  • the container has a bottom wall that is at least partly formed by the heat-conductive plate that at least partly lines the product receiving chamber.
  • the container bottom wall may comprise thermally-insulating material. If the container bottom wall comprises thermally-insulating material, such material preferably contains an opening for exposing part of the heat-conductive plate to the outside at the lower end of the container so that it can be brought in heat-conductive contact with the support of the storage rack when the container is placed on the support.
  • the heat-conductive plate preferably at least lines the bottom surface of the product receiving chamber, more preferably the bottom and part of any side surfaces of the product receiving chamber.
  • the plate may for example be in the form of a bottom plate lining the bottom surface of the product receiving chamber, an U-shaped plate lining the bottom surface and at least part of two side surfaces, or a double U-shaped plate lining the bottom surface and at least part of four side surfaces of the product receiving chamber.
  • the heat-conductive plate is exposed to an outside of the product container at the lower end of the container.
  • the heat-conductive plate preferably is composed of a single sheet that may be bent in an U-shape or double U-shape if lining both the bottom surface and part of a side surface of the product receiving chamber.
  • the heat-conductive plate may be composed of multiple sheets that are heat-conductively connected to each other, for example by a welded or brazed joint.
  • the heat-conductive plate may comprise one or more additional surfaces that project into the product receiving chamber to increase the surface area of the heat-conductive plate inside the product receiving chamber to increase heat exchange capacity.
  • the additional surface may for example form a vertical separation wall in the product receiving chamber.
  • the heat-conductive plate preferably is a metal plate, more preferably a plate made of an aluminium alloy. Aluminium alloy in particular offers a suitable balance between a relatively large thermal conductivity and a relatively low weight.
  • the heat-conductive plate may have any suitable thickness, preferably a thickness in the range between 1 mm and 5 mm, more preferably of from 1.5 to 4 mm.
  • the product container is composed of four side walls of thermally-insulating material connected to each other at square angles and a metal heat-conductive plate insert, preferably an U-shaped or double U-shaped metal plate insert that tightly fits within the four side walls.
  • a product container is formed with a product receiving chamber that is lined at its bottom end and at part of its side walls with the metal plate.
  • the top end of the container may be opened and closed with a top lid, preferably a top lid of the same thermally-insulated material as the side walls.
  • the side walls may comprise an inwardly protruding ridge for supporting the metal insert.
  • the system comprises at least one storage rack for supporting the product containers.
  • the storage rack comprises a hollow frame formed by a plurality of hollow tube elements of heat-conductive material.
  • the tube elements are interconnected to define a fluid flow path for a heat-transfer fluid between a fluid inlet and a fluid outlet of the hollow frame.
  • the hollow frame provides a support for the product containers and provides shape and strength to the rack.
  • cooled or heated heat-transfer fluid from the temperature-regulating device flows through the fluid flow path defined by the hollow frame of the storage rack for temperature control of product in any product container placed on the support provided by the hollow frame and in heat-conductive contact with the support via the heat-conductive plate exposed to an outside of the container.
  • the tube elements are made of heat-conductive material, preferably of metal, more preferably of an aluminium alloy.
  • the tube elements may for example be aluminium alloy extrusion profiles.
  • the hollow frame is formed by connecting the plurality of tube elements to each other, for example by welding.
  • the hollow frame of the storage rack is preferably configured to support in the range of from 4 to 50 product containers, more preferably of from 8 to 40 product containers, even more preferably of from 16 to 30 product containers, in such a way that each container can be brought in direct heat-conductive contact with the support provided by the hollow frame.
  • the hollow frame may support the multiple product containers in a row, i.e. next to each other, and/or above each other, preferably in several rows above each other.
  • the hollow frame may for example be configured to support 20 product containers in four rows above each other, wherein five product containers are supported in each row.
  • the hollow frame of the storage rack is configured such that it can support product containers with no or only a small gap between adjacent product containers.
  • the hollow frame can support containers in several support rows above each other, the hollow frame is preferably configured such that the distance between the top end of a product container in a support row and the part of the hollow frame providing the above support row is minimized for the same reason.
  • the fluid flow path defined by the hollow frame is configured such that under normal operation of the system, heat-transfer fluid flows through the entire fluid flow path. Not all of the heat-transfer fluid supplied via the fluid inlet may flow through the entire fluid flow path (in other words: heat-transfer fluid may have different trajectories through the fluid flow path), but the fluid flow path is configured such that the hydraulic resistance of any possible trajectory of heat-transfer fluid is substantially equal so that there is an equal flow of heat-transfer fluid at any point in the fluid flow path and the heat-conductive capacity of the frame via the heat-transfer fluid flowing though the frame is the same at any location of the frame. It will be appreciated that the length, diameter, and shape of the fluid flow part and the positions of the fluid inlet and the fluid outlet will affect the hydraulic resistance. It is within the skills of the skilled person to configurate a fluid flow path with such substantially equal hydraulic resistance of any possible trajectory of heat-transfer fluid.

  • the fluid inlet and the fluid outlet may be positioned at any suitable location of the hollow frame.
  • the storage rack preferably comprises thermally-insulating material configured such that the hollow frame is partly embedded in the thermally-insulating material. More preferably, the hollow frame is partly embedded in thermally insulating material, in such a way that it comprises container locations for supporting a product container at which the heat-conductive material of the tube elements is exposed (not embedded in thermally-insulating material) for direct heat-conductive contact with the part of the heat-conductive plate that is exposed to an outside of the product container. In other words, at such container locations a top surface of the support provided by the hollow frame is exposed and can be brought in direct heat-conductive contact with the exposed heat-conductive plate at the outside of the product container, typically at its lower end, when the product container is placed on the support at the contained location.
  • the thermally insulating material is configured to thermally insulate the hollow frame where it will not be in heat-conductive contact with the product container.
  • the part of the heat-conductive plate exposed to an outside of the product container may have a surface area that is larger than the surface area of the hollow frame that is in direct heat-conductive contact with such exposed part when the product container is placed on the support.
  • the part of the exposed heat-conductive plate not in direct contact with the hollow frame may be covered by thermally-insulated material, for example by providing the hollow frame with thermally-insulated material between tube elements that support a product container.
  • the thermally-insulating material comprised in the storage rack may be any suitable thermally-insulating material, for example expanded polystyrene or polyurethane foam. Expanded polystyrene is a particularly preferred thermally-insulating material, since it combines good thermal insulation properties with a relatively low weight.
  • the storage rack is a mobile storage rack, comprising one or more wheels.
  • a mobile storage rack is a benefit when the system is used in a vehicle, since multiple product containers can be moved into the vehicle simultaneously, by simply wheeling the storage rack with product containers into a cargo space of the vehicle.
  • the system comprises a temperature-regulating device, configured to cool or heat a heat-transfer fluid, wherein the device comprises a device inlet for the heat-transfer fluid and a device outlet for cooled or heated heat-transfer fluid.
  • the device outlet is fluidly connectable to the fluid inlet of the hollow frame and the device inlet is fluidly connectable to the fluid outlet of the hollow frame.
  • the respective inlets and outlets are fluidly connected so that heat-transfer fluid can circulate from the temperature-regulating device through the fluid flow path defined by the hollow frame of the storage rack and back to the temperature-regulating device.
  • the fluid connection between the respective inlets and outlets may for example be established by means of a flexible conduit such as a hose.
  • quick connectors may be provided at the respective inlets and outlets to minimize time required to establish the connections and to improve user-friendliness.
  • the system may comprise a pump or other means for circulating the heat-transfer fluid, preferably a pump in the temperature-regulating device.
  • heat-transfer fluid is a liquid.
  • Suitable heat-transfer fluids are known in the art and include alcohol-water mixtures or aqueous salt solutions (often referred to as brines). Examples of suitable alcohol-water mixtures are mixtures of ethylene glycol, diethylene glycol and/or propylene glycol and water.
  • Temperature-regulating devices are well known in the art. Any suitable temperature-regulating device may be used.
  • the temperature-regulating device preferably is a cooling device.
  • Such cooling device is configured to supply cooled heat-transfer fluid at its device outlet.
