Thermal insulation box with cooling mechanism
The invention relates to a smart thermal insulation box, including thermally insulated layers with mitered edges forming a thermally insulated space, and said space surrounded by cardboard material. The box has externally viewable and operable temperature and humidity sensors, where the sensors are preferably fixed inside the box to one side. The temperature monitoring system monitors temperature of the insulated space and facilitates delivery of refrigerant into it through a refrigerant delivery system when the temperature of insulated space exceeds a set value. One of the cardboard panels forming the top of the box which overlays the insulation layer has a window configured to overlay the display panel. An audible alert system may also be included to alert users to temperature or humidity excursions.
1. A smart thermal insulation box consisting essentially of:
an insulated box having a top, a bottom and sides, each formed of one of eight panels of expanded polystyrene with mating mitered edges;
an outer corrugated box with a top, a bottom and sides which overlay the respective top, bottom and sides of the insulated box, and wherein the outer corrugated box is configured to accommodate the insulated box;
temperature and humidity sensors positioned inside the insulated box and electrically connected with an externally viewable display panel showing the temperature and humidity detected by the sensors, wherein components associated with operating the display panel reside in a first of the eight panels, where said first panel faces the top of the box, and where the top of the corrugated box has a window configured to overlay the display panel; and
a refrigerant container positioned on the outer side of one side of the corrugated box, which, based on input from the sensors indicating temperature and humidity inside the insulated box exceeds a threshold, refrigerant enters into the insulated box.
2. The smart thermal insulation box of claim 1 wherein the temperature and humidity sensors are fixed in a recess with mating hook and loop fasteners in one of the side panels of the insulated box.
3. The smart thermal insulation box of claim 1 wherein the temperature and humidity sensors reside on a single pad having one portion of a mating hook and loop fastener.
4. The smart thermal insulation box of claim 1 further including piping connecting the refrigerant container to an inner portion of the insulated box wherein the sensors control a valve which is positioned in the piping.
5. The smart thermal insulation box of claim 1 wherein said components include a processor board, a beeper for providing audible alarms and an LCD or LED display screen for displaying the temperature and humidity detected by the sensors.
6. The smart thermal insulation box of claim 5 wherein the processor board includes a microprocessor, having memory and associated circuitry for sensing outputs from the sensors and displaying the temperature and humidity on the display screen.
7. The smart thermal insulation box of claim 1 wherein the corrugated box is cardboard or plastic.
8. The smart thermal insulation box of claim 1 wherein the window in the corrugated box is capable of being opened.
9. The smart thermal insulation box of claim 1 wherein the window in the corrugated box is clear plastic.
