In the materials of the article, the following issues are considered in relation to this problem: the efficiency of temperature reduction in a thermoelectric cooler; the nature of the destruction of an electric charge by thermal impulses; operating modes of thermopiles in brake friction pairs. The purpose of the article is to reduce the value of the ratio between the Peltier ("useful") and Joule ("harmful") effects in electric and thermal currents circulating in the thermopile branches, and the use of thermoelectric cooling in the friction pairs of the tape-shoe brake of the drawworks. The thermopiles installed in the friction linings of the brake band on its incoming and outgoing branches operated in the modes of a thermoelectric cooler and a thermoelectric generator, respectively. It has been established that when the energy loading is quasi-leveling in terms of the belt sweep angle of the pulley, the following is achieved on average: a decrease in energy loading to 20 %, an increase in the dynamic coefficient of friction by 11 %, and a decrease in liner wear by 8.5 % when they operate in the range of surface-bulk temperatures below the acceptable value for their materials.
