The invention relates to the technical field of cooling, and discloses a return water cooling system and its control method. The return water cooling system includes a cold water supply pipe, a cooling water supply pipe and a return flow pipe. The cold water supply pipe includes a plurality of water supply branches, and each water supply branch All roads are equipped with control valves, and multiple control valves are electrically connected to the PLC controller; one end of the cooling water supply pipe is connected to the water outlet of multiple water supply branches, and the other end is connected to the water inlet of the equipment to be cooled. A temperature sensor electrically connected to the PLC controller is provided; one end of the return water pipe is connected to the water outlet of the equipment, and the other end is connected to the cooling water supply pipe, and the return water pipe is provided with a water outlet. The return water cooling system is controlled by the PLC controller to control the opening and closing of the control valve to mix and cool the return water with different flows. The operation is simple and convenient, and no heat exchanger is needed, the equipment installation space is reduced, the workshop construction cost and the initial equipment investment The cost is reduced, and there is no need for regular maintenance and cleaning of the heat exchange plate.
Description
technical field [0001] The invention relates to the technical field of cooling, in particular to a return water cooling system and a control method thereof. Background technique [0002] The cooling circulation system of the workshop equipment usually uses a heat exchanger to communicate with the equipment to be cooled in fluid to form a cooling circulation system. Specifically, the cooling water pipe is connected to the water inlet of the equipment to be cooled to provide cooling water for the equipment to be cooled, and the water outlet of the equipment is connected to the return water pipe to discharge the return water after cooling the equipment to the heat exchanger for cooling , the water cooled by the heat exchanger is reused to cool the equipment. [0003] The above-mentioned cooling circulation system needs to be equipped with a heat exchanger, and the initial investment of assembling the heat exchanger and the water pump is high, and the floor area is large; and t...
