SHAFT PLANT FOR HEAT TRANSFER OVER LONG DISTANCES AT LOW TEMPERATURE DIFFERENCES Russian patent published in 2019 - IPC F28D15/02 F25B21/02 F25B7/00 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering, in particular to systems for providing thermal conditions based on contour heat pipes. Shaft unit for heat transfer over long distances at small temperature drops comprises thermoelectric battery and contour heat pipe. Cold junction of thermoelectric battery is conjugated with cooled object, and switching plate of hot junction is with evaporator of contour heat pipe. In the shaft installation located in the vertical mine structure, the cooled object with the contacting cold junction of the thermoelectric battery is placed in the upper part of the mine structure with a higher temperature, and the contour heat pipe capacitor is located in the lower part of the mine structure with low temperature and is in heat exchange by radiation and convection with walls of the mine structure.

EFFECT: creation of a reliable device with a simplified design, operable at any orientation in the field of gravity forces and capable of transmitting heat over long distances at low temperature drops and low power consumption.
