Unit load device and method for storing and transporting articles
The present disclosure relates to a unit load device and a method for storing and transporting articles. The unit load device includes: a housing defining an internal space and an opening to the internal space; and a cover configured to operably open or hermetically close the opening; wherein the housing is provided with a housing temperature control layer containing at least a first phase change material, and/or the cover is provided with a cover temperature control layer containing at least a second phase change material, so that during storage of articles in the internal space hermetically closed by the cover, a temperature of the internal space is within a preset temperature range after a preset period of time has elapsed.
1. A unit load device, comprising:
a housing defining an internal space and an opening to the internal space; and
a cover configured to operably open or hermetically close the opening,
wherein the housing is provided with a housing temperature control layer containing at least a first phase change material, and/or the cover is provided with a cover temperature control layer containing at least a second phase change material, so that during storage of articles in the internal space hermetically closed by the cover, a temperature of the internal space is within a preset temperature range after a preset period of time has elapsed;
a refrigeration unit configured to provide refrigeration to the internal space, the refrigeration unit located in an additional housing exterior to the unit load device, the refrigeration unit providing cooled air to the internal space through an air flow channel between the additional housing and the internal space.
2. The unit load device according to claim 1 , wherein the housing temperature control layer is detachably installed on at least a part of an inner wall and/or at least a part of an outer wall of the housing, and/or the cover temperature control layer is detachably installed on at least a part of an inner wall and/or at least a part of an outer wall of the cover.
3. The unit load device according to claim 1 , wherein the housing temperature control layer further contains a first rigid reinforcement material mixed with the first phase change material, and/or the cover temperature control layer further contains a second rigid reinforcement material mixed with the second phase change material, and the first rigid reinforcement material or the second rigid reinforcement material comprises a porous foamed metal.
4. The unit load device according to claim 1 , wherein the housing temperature control layer and the cover temperature control layer are provided to have different temperature control performances, and/or the housing temperature control layers located in at least two different areas on the housing are provided to have different temperature control performances, and/or the cover temperature control layers located in at least two different areas on the cover are provided to have different temperature control performances.
5. The unit load device according to claim 4 , wherein the first phase change material and the second phase change material are different, and/or the first phase change materials contained in the housing temperature control layers located in at least two different areas on the housing are different, and/or the second phase change materials contained in the cover temperature control layers located in at least two different areas on the cover are different; and/or
the housing temperature control layer and the cover temperature control layer have different thicknesses, and/or the housing temperature control layers located in at least two different areas on the housing have different thicknesses, and/or the cover temperature control layers located in at least two different areas on the cover have different thicknesses.
6. The unit load device according to claim 1 , wherein a thermal insulation layer is further provided on the housing and/or the cover.
7. The unit load device according to claim 1 , further comprising:
a temperature sensor configured to detect the temperature of the internal space; and
a controller, which is connected to the temperature sensor and the refrigeration unit, and is configured to turn on or off the refrigeration unit when a detected current temperature of the internal space reaches a threshold thereof, so that the temperature of the internal space is within the preset temperature range.
8. A method for storing and transporting articles, comprising:
providing one or more unit load devices according to claim 1 ;
storing articles to be transported in the internal space hermetically closed by the cover of the unit load device; and
transporting the unit load device to a destination by using transportation means.
9. The method for storing and transporting articles according to claim 8 , further comprising:
replacing at least one of the housing temperature control layer and the cover temperature control layer on the unit load device during the transportation or after arriving at the destination.
10. The method for storing and transporting articles according to claim 9 , further comprising:
restoring energy of the housing temperature control layer and/or the cover temperature control layer that have been replaced, for reuse.
11. The method for storing and transporting articles according to claim 8 , wherein the transportation means comprise aviation aircraft, water vehicles, rail trains, and road vehicles, and the articles are temperature-sensitive articles comprising medical products, biological agents, organs and food.
