Abstract

The invention discloses a temperature control circuit system applied to cesium furnace heating, and belongs to the technical field of cesium metal production. Comprising a 220V alternating current power supply, a short circuit protection unit, a direct current voltage stabilization unit, a main control chip, a temperature heating unit, a temperature control unit, a temperature detection unit and an LCD display unit. The short circuit protection unit is electrically connected with the 220V alternating current power supply and the direct current voltage stabilization unit, the temperature heating unit is electrically connected with the main control chip and the cesium furnace, the temperature control unit is electrically connected with the main control chip and the temperature detection unit, and the temperature detection unit is electrically connected with the temperature control unit and the cesium furnace. Heating and cooling of the cesium furnace can be controlled, the constant-temperature state can be maintained, it is guaranteed that metal cesium cannot be condensed into a solid state after being gasified in the cesium furnace, solid cesium is prevented from blocking the interior of a pipeline, and therefore smooth conveying of gaseous cesium by the cesium furnace is guaranteed. The system also rapidly protects the circuit system through the short-circuit protection unit.
