This specification relates to temperature regulation systems and devices, particularly systems and devices for uniform temperature regulation in modular shipping containers.
In the health, medical, pharmaceutical, and/or life science industries, safe storage and fast transportation of payloads in a temperature-controlled and watertight environments is important. Hardened reusable shipping containers that maintain, regulate, or control the payload area temperature are desirable in transporting temperature sensitive payload in such industries. The payload area temperature may be maintained by using phase change materials (e.g., dry ice). Generally, dry ice is disposed over, under, and/or on the sides of a payload using trays that contain the dry ice. However, temperature inside the payload area may not be uniform with such a configuration. Instead, temperature may be warm over the payload and cold under the payload due to the dry ice sublimating and traveling down to the bottom of the payload area where the payload sits on dry ice.
As such, there is a need for systems and devices to provide uniform temperature distribution inside the payload area and to increase cooling capacity.
In general, one aspect of the subject matter described in this specification is embodied in a tray for uniformly cooling a payload. The tray may have a body. The body may have an internal wall panel, and a plurality of side panels in connection with the internal wall panel, and a plurality of dividers. The dividers may be in connection with the internal wall panel and one or more of the plurality of side panels. The plurality of dividers may define a plurality of chambers, each chamber of the plurality of chambers is at least partially bounded by (i) at least one divider of the plurality of dividers, (ii) the internal wall panel. Each chamber of the plurality of chambers may be configured to receive a portion of a cooling agent inserted into the body. A cover panel may be attached to the body.
This and other embodiments may optionally include the plurality of side panels comprising one or more tabs. The cover panel may be configured to attached to the body by the one or more tabs on the side panels. The internal wall panel may comprise a plurality of holes. A fastener may be attached to the body to couple the tray to a second tray. The body of the tray may have a trapezoidal shape. The cooling agent may be dry ice, or any other solid cooling agent, gel cooling agent, cryogen, or the like.
The dividers may define four or more chambers of the plurality of chambers in the body of the tray. The cooling agent may be disposed inside each chamber of the plurality of chambers of the body of the tray.
In another aspect, the subject matter may be embodied by a tray system for uniformly cooling a payload. The tray system may comprise a plurality of trays. Each tray of the plurality of trays may comprise an internal wall panel, a plurality of side panels in connection with the internal wall panel, a plurality of dividers in connection with the internal wall panel and one or more of the plurality of side panels, and a cover panel attached to the plurality of side panels. The dividers may define two or more chambers configured to receive a cooling agent inserted in each of the chambers
In this and various embodiments, the plurality of trays may be configured to enclose a payload from six sides. The cover panel may be attached to the plurality of side panels by one or more tabs. Each of the plurality of trays may have a trapezoidal shape for the plurality of panels to fit together to form a box. Each of the plurality of trays are attachable to one another by fastener.
The plurality of trays may be stackable on top of each other for storage. The tray system may further comprise a band configured to wrap around and bundle the plurality of trays.
In another aspect the subject matter may be a system for shipping a uniformly cooled payload. The system may include an outer enclosure and an inner enclosure. The outer enclosure may have a cavity. The inner enclosure may be positioned within the cavity of the outer enclosure comprising a plurality of trays. The plurality of trays of the inner enclosure define a payload area. The plurality of trays may comprise a plurality of dividers and a cooling agent separated by the dividers.

The plurality of trays may include a top tray, a plurality of side trays and a bottom tray that is opposite the top tray. The plurality of side panels of the top tray may interface with a side panel of each of the plurality of side trays. The plurality of side panels of the bottom tray may interface with a side panel of each of the plurality of side trays. The side panels of the plurality of side trays may interface with each other. The outer enclosure may include a base and a lid, wherein the lid is removable to access the inner enclosure when the inner enclosure is within the cavity of the outer enclosure. Each of the plurality of trays may be attachable to one another by a fastener.
A method is also disclosed. The method may be for maintaining temperature of a payload area of a shipping container. The method may include inserting a cooling agent into a plurality of trays, wherein the trays comprise dividers to disperse the cooling agent. The method may include attaching a cover panel to each of the plurality of trays. The method may include connecting the plurality of trays to form an inner enclosure, the inner enclosure defining the payload area.
In various embodiments, the method may include receiving a payload by the payload area of the inner enclosure. The method may include cooling the payload area by the cooling agent to maintain the payload area within a predetermined temperature range. The method may include placing the inner enclosure into a cavity of an outer enclosure, the outer enclosure having a plurality of side panels and a base defining the cavity in the outer enclosure.

The predetermined temperature range may be between about 25 degrees Celsius to about −80 degrees Celsius. The method may include wherein each of the plurality of trays are configured to connect to each other by a plurality of side walls.
Other systems, methods, features, and advantages of the present disclosure will be apparent to one skilled in the art upon examination of the following figures and detailed description. Component parts shown in the drawings are not necessarily to scale and may be exaggerated to better illustrate the important features of the present disclosure.
Disclosed herein are uniform temperature distribution systems and trays. The systems and trays may include or be used in conjunction with modular shipping containers configured to be temperature regulated with a cooling agent such as dry ice or another phase change material (PCM). The trays may be disposed around a payload of a shipping container from within a payload area situated in a base enclosure of the shipping container. The trays may enclose the payload from all six sides such as to create a box or box-like structure. The trays may each have a housing that is internally segmented. For instance, the housing may be divided into chambers or pockets on top of one another. Each chamber may be packed with a cooling agent such as dry ice. The internally segmented arrangement of the chambers may prevent the dry ice from sinking to the bottom of the payload once sublimated. Instead, the dry ice is trapped within the confinements of each of the chambers, and thus may provide uniform temperature distribution within the shipper and increase the cooling capacity of the shipper.
Other benefits and advantages include the trays being attachable to each other or foldable or stackable. For instance, the trays may each have a trapezoidal shape that enables easy joining of the trays. The trays may also be stacked on top of each other when not in use to be stored.
