Temperature regulating device applied to submersible

The utility model discloses a temperature regulating device applied to a submersible. The temperature regulating device applied to the submersible comprises a water storage tank fixedly installed on the outer wall of a submersible shell body and a heat exchanger arranged inside the submersible shell body. A water inlet end of the water storage tank is connected with the heat exchanger through a water inlet pipeline and a water outlet end of the water storage tank is connected with the heat exchanger through a water outlet pipeline. According to the temperature regulating device applied to the submersible, seawater is utilized to conduct heat exchanging, so that refrigeration effect is realized and large power consumption of the refrigeration in a traditional refrigerating unit is reduced. Refrigerating fluid is not needed but small amount of power is used to drive the fresh water in a closed system to cycle, so that air in the cabin of the submersible under the water is cooled.
