FIELD: heat engineering; may be used for temperature control of various objects in chemical, pharmaceutical and food industries, in medical diagnostics and biological studies and tests, for instance, in criminology. SUBSTANCE: device comprises container with object, temperature sensor, heat transfer means contacting container connected to source of cold, source of heat, control unit whose input is coupled to temperature sensor. Heat transfer means is manufactured in the form of gas conduit filled with noncondensing gas with blower. Gas conduit contacts side surface of container made from heat transfer material. Source of heat is made in the form of resistive heater and is placed inside container with fan. Outputs of control unit are connected to blower and resistive heater. To raise efficiency of device, control unit is linked to cold source. EFFECT: reduced inertia of device, increased rate of changing the temperature of object and precision of specified temperature under static conditions. |
