A portable, independent thermoelectric temperature regulated system for providing active cooling to one or more payloads. The system includes a thermally insulated housing, a phase change material, one or more thermoelectric converters embedded in the thermally insulated housing, and a power source. The system includes a control circuit for managing temperature of the payload(s) based on user selections. The phase change material may be charged and discharged to provide passive cooling or heating when the thermoelectric converter is not active.

Portable regulated temperature container with phase change materials

A portable, independent thermoelectric temperature regulated system for providing active cooling to one or more payloads. The system includes a thermally insulated housing, one or more thermoelectric converters embedded in the thermally insulated housing, and a power source. The system may include one or more optional payload containers. Multiple payload containers may be used in the same housing. The system includes a control circuit for managing temperature of the payload(s) based on user selections. The housing may be hard or soft, and the multiple payload containers may be maintained at different temperatures. Optional phase change materials may be included that may be charged by the active thermoelectric converter discharged as a source of passive cooling or heating.

Portable temperature regulated container

A method and system for efficiently cooling a fluid is provided. A cooling system includes a first chamber containing a first fluid, and a second chamber connected to the first chamber and containing a second fluid. The cooling system further includes one or more thermoelectric devices for cooling the second fluid in the second chamber, and a first body that acts as a thermal diode. The first body enables unidirectional transfer of heat from the thermoelectric devices to the first fluid. Further, the cooling system can be installed with one or more phase change materials or heat pipes that enhance the cooling efficiency of the cooling system. The thermoelectric devices are switched on for a certain time period, after which they are switched off and on repeatedly in cycles, depending on the temperature of the second fluid.

Method and apparatus for switched thermoelectric cooling of fluids

In various embodiments of the present invention, a thermoelectric device is provided. The thermoelectric device includes one or more thermoelements that transfer heat across the ends of the thermoelectric device. A method for creating the thermoelectric device includes forming a metal substrate, and etching one or more surfaces of the metal substrate to form etched portions. The unetched flat portions on the metal substrate are referred to as mesa cores. Thereafter, thermoelectric films are deposited on the one or more surfaces of the metal substrate. The deposition of the thermoelectric films on the mesa cores results in the formation of a thermoelement.
