The patent publication No. CN110667257A discloses an ink thermostatic control device, which comprises a heat exchanger and a temperature regulating device, wherein a reciprocating flow passage is arranged in the heat exchanger to prolong the flowing time of ink in the heat exchanger, and the temperature regulating device is a heating plate or a refrigerating plate, namely, the temperature of the ink flowing in the heat exchanger is increased or reduced by heating or refrigerating the heat exchanger so as to achieve the effects of regulating temperature and controlling temperature.

However, in the technical solution disclosed in the above patent, only the heating plate or the cooling plate is provided on the heat exchanger, which means that only the ink passing through the heat exchanger can be heated or cooled, resulting in poor temperature adjustment effect on the ink, and in the environment temperature in different seasons, such as when the cooling plate is used in summer, the temperature reduction effect on the ink is better, and once in winter, the temperature adjustment effect on the ink is reduced due to the fact that only the cooling is performed and the environment temperature is lower, and the ink temperature cannot be guaranteed to be within a certain value; on the contrary, if the heating plate is used, the temperature adjusting effect in winter is good, and the effect in summer is poor.

Therefore, there is a need to design a temperature control system capable of both heating and cooling.
