Laser cooling-water machine capable of switching between single-temperature mode and double-temperature mode

The utility model belongs to the technical field of refrigerating devices matched with optical fiber laser equipment, and particularly relates to a laser cooling-water machine capable of switching a single-temperature mode and a double-temperature mode. Comprising a cold water tank, a condenser, a heat-conducting coil, a compressor, a main circulating pump and an electric heating device, the coil pipe is arranged in the cold water tank; the system further comprises a refrigerating loop, a low-temperature load pipeline, a normal-temperature load pipeline, a water return pipeline and a normal-temperature circulating pipeline. Low-temperature cooling water and normal-temperature cooling water can be stably output, meanwhile, a single-temperature or double-temperature supply structure can be rapidly switched, the utilization efficiency of a cold source is improved, the refrigeration output pressure of the condenser is reduced, and an electric heating structure is independently arranged so that the water temperatu
