The utility model discloses a
liquid temperature control device. The
temperature control device comprises a temperature conveyor and a
temperature control system; the temperature conveyor comprises a heating component, and the heating component is arranged in a hollow mode to form a
refrigeration channel. A
heat supply main body of the heating component is located in liquid to be subjected to
temperature control, and the heating end of the heating component and the input end and the output end of the
refrigeration channel are connected with the temperature
control system. According to the temperature conveyor, the heating component in the temperature conveyor is arranged to be the hollow component, the hollow part forms the refrigerating channel, the heating and refrigerating
integrated design is achieved, the situation that a
heating system and a refrigerating
system need to be connected with a sleeve pipeline
system is avoided, system pipelines are simplified, and the complexity of system design and installation is reduced; through the structure, the problems of complicated installation, low efficiency and the like caused by separation of a
heating system and a refrigerating system of a traditional liquid cooling device are solved.
