FIELD: automatic temperature control systems. SUBSTANCE: device has a radiator filled with liquid coolant, temperature sensor and control unit connected in series and mounted in a housing, cooling fan with a drive the output of which is connected to the output of control unit. The control unit has a head-conducting housing comprising a protrusion and mounted within the radiator such that the protrusion is in contact with the liquid coolant, the control unit housing being filled with a heat-conducting filler which is isolated from the walls of housing except of the protrusion. The temperature sensor is disposed within the control unit housing protrusion and is fixed directly to the protrusion end-face being in contact with the liquid coolant by its one end-face. EFFECT: enhanced accuracy in maintaining temperature of liquid coolant. 2 dwg
