FIELD: survey of boreholes or wells, particularly in borehole geophysical instrument requiring additional thermal stabilization.
SUBSTANCE: mounting with members to be thermostated is arranged inside heat absorbing device. Heat absorbing device is made as a set of heat absorbers, each of which is made as hollow heat-conductive cylinder filled with heat absorbing material. Heat insulator is formed as cylindrical heat-protective shell with outer and inner ring-shaped ribs and adapted for receiving heat absorbers. Heat-conductive mounting have heat absorbing plugs connected to ends thereof. Each heat-absorbing plug is made as hollow heat-conductive cylinder filled with heat absorbing material. Surfaces of heat-protective case, heat-protective cylindrical shell, heat absorbers and heat absorbing plugs facing thermostating members are covered with heat absorbing coating. Surfaces thereof facing borehole are covered with heat-reflecting coating.
EFFECT: increased duration of working thermostating cycle and simplified structure of thermostat.
