Strategic Insights

— 2 min read

A patent application has been filed by inventor Ahmed, Faizan, for a portable temperature-controlled enclosure featuring a front-loaded aluminum payload chamber designed for efficient storage and easy access. The device utilizes a semiconductor chip mounted at an optimized angular orientation to create a radial cooling pattern, ensuring precise temperature control throughout the enclosure. The system incorporates a sophisticated closed-loop cooling mechanism and a versatile power system capable of running on both standard wall power and battery power for portable use.

Key Takeaways:

  • The portable temperature-controlled enclosure features a front-loaded aluminum payload chamber with a semiconductor chip mounted at an angle between 15 and 20 degrees relative to the chamber wall to create a radial cooling pattern.
  • The closed-loop cooling system comprises fluid-carrying pipes directly coupled to the posterior surface of the semiconductor chip, a working fluid, an integrated pump mechanism, and a fan-assisted heat exchanger.
  • The power system includes a lithium polymer battery assembly configured to provide 72 hours of autonomous operation, universal AC power input compatibility for 110V and 220V, and intelligent power switching circuitry for transitioning between wall power and battery power.
  • The control system consists of temperature sensors for continuous monitoring, an integrated LTE module with SIM card, GPS location tracking capability, and local data storage on an SD card.
  • The portable temperature-controlled enclosure has an internal volume of one liter, dimensions of 107.78 mm x 119.92 mm x 166.84 mm, and a specialized heat-absorbing material combined with aluminum.
  • The control system is configured to achieve initial cooldown to 2° C. within 2 hours, maintain temperature between 2-8° C., operate in both standard cooling and winter heating modes, and provide automated cooling bursts for temperature deviation compensation.

Statistics:

  • The portable temperature-controlled enclosure has an internal volume of one liter, dimensions of 107.78 mm x 119.92 mm x 166.84 mm.
  • The lithium polymer battery assembly is configured to provide 72 hours of autonomous operation.
  • The control system consists of temperature sensors for continuous monitoring.
  • The portable temperature-controlled enclosure features a semiconductor chip with multiple semiconductor junctions arranged in an optimized pattern.
  • The system includes a high thermal conductivity compound, controlled thickness application, full surface coverage verification, and a spring-loaded mechanism maintaining 30-40 PSI mounting pressure.
  • The control system is configured to maintain precise target temperatures within the front-loaded payload chamber, making it ideal for applications requiring strict temperature control.
