PORTABLE THERMOSTATIC UNIT Russian patent published in 2019 - IPC F25D3/14 

FIELD: storage; transport facility.

SUBSTANCE: invention can be used for storage and transportation of biopreparations. Portable thermostatic unit comprises a heat container, inside of which there is a heat exchange chamber with a built-in thermal sensor, and a Ranque-Hilsch vortex tube. Vortex tube inlet is connected to compressed air source by means of electromagnetic pneumatic valve and filter, and outlets are connected to heat exchange chamber inlet by means of two-channel pneumatic distributors of cold and hot outlets of vortex tube. Proposed unit comprises programmed control board equipped with USB connector and connected with electromagnetic pneumatic valve, two-channel air distributors of vortex tube cold and hot outlets, thermal sensor and LCD-monitor with buttons. Thermogrules are arranged along the perimeter between the thermal container and the heat exchange chamber of the installation.

EFFECT: enabling control and maintenance of the required temperature mode inside the thermal container with accuracy of tenths of degrees Celsius in a wide temperature range, which is a prerequisite for storage and transportation of heat-sensitive biological objects.
