[0024] The following is combined with Figure 1-4 The utility model is further described.

[0025] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a temperature control device for synthesizing adiponitrile by electrolytic dimerization of acrylonitrile.

[0026] The specific technical solution includes: a mixing tank 1, a natural cooling component 2, a flippable cooling module 3 and a thermometer 4;

[0027] like Figure 1-2 As shown, a liquid inlet pipe 5 is fixedly installed at one end of the mixing tank 1, and the liquid inlet pipe 5 can conveniently add liquid substances to the mixing tank 1; a support leg 6 is welded to the side wall of the mixing tank 1, and the support leg 6 is used to support the stability of the mixing tank 1; the natural cooling component 2 surrounds the side wall of the mixing tank 1, and the two ends of the natural cooling component 2 are respectively fixedly connected to the two ends of the mixing tank 1, and the natural cooling component 2 is used for natural cooling of the coolant; one end of the flippable cooling module 3 is fixedly penetrated through the side wall of the natural cooling component 2, and the flippable cooling module 3 is fixedly connected to the mixing tank 1. Used to accelerate the mechanical cooling of the coolant; the thermometer 4 is fixedly mounted on the flip cooling module 3, and the thermometer 4 is used to monitor the air temperature. When the temperature is lower than the set value, the coolant circulates in the natural cooling component 2, and the coolant exchanges heat with the external air temperature and cools down naturally, and then flows back to the mixing tank 1. When the temperature is higher than the set value, the coolant circulated through the natural cooling component 2 enters the flip cooling module 3, and is started by the flip cooling module 3, which can fully cool the coolant and then send it to the mixing tank 1, which can help reduce energy consumption.

[0029] When the water pump 1 201 is started, the coolant is drawn from the mixing tank 1 into the annular tube 202. The annular tube 202 is exposed to the air. The coolant in the annular tube 202 can exchange temperature with the air through the tube wall of the annular tube 202. The external air temperature is lower than the temperature of the coolant in the annular tube 202. The temperature of the coolant in the annular tube 202 decreases. When the thermometer 4 detects that the ambient temperature is lower than the set value, the coolant can be cooled to the required value by the external air.

[0031] The coolant in the water inlet pipe 205 enters the refrigeration box 301, and the semiconductor refrigeration sheet 302 is started to cool the bottom of the refrigeration box 301.
