Abstract

The invention relates to the technical field of cooling and discloses a return water cooling system and a control method of the return water cooling system. The return water cooling system comprises acold water supply pipe, a cooling water supply pipe and a return water pipe. The cold water supply pipe comprises multiple water supply branch pipes. A control valve is mounted on each water supply branch pipe. The control valves are electrically connected with a PLC. One end of the cooling water supply pipe is connected with water outlet ends of the water supply branch pipes, and the other end of the cooling water supply pipe is connected with a water inlet of to-be-cooled equipment. The cooling water supply pipe is provided with a temperature sensor electrically connected with the PLC. Oneend of the return water pipe is connected with a water outlet of the equipment, and the other end of the return water pipe is connected with the cooling water supply pipe, and a water outlet is formedin the return water pipe. According to the return water cooling system, the opening of the control valves is controlled by the PLC so that return water of different flows can be mixed and cooled, theoperation is easy and convenient, no heat exchanger is needed, the equipment mounting space is reduced, the workshop building cost and the initial equipment investment cost are lowered, and the costin regularly maintaining and cleaning heat exchange boards is omitted.

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...
