Cast aluminum heat exchanger detection control method, control device and system

The invention belongs to the field of cast aluminum heat exchanger manufacturing, and particularly relates to a cast aluminum heat exchanger detection control method, control device and system. A water tank, a water pump, a water flow detector, a first annular plate and a second annular plate are arranged; clear water in the water tank is poured into a water channel of the heat exchanger through the water pump, metal particle impurities in the heat exchanger are brought out, water flow passes through a bent channel formed by the first annular plate and the second annular plate, metal particles in the water flow are precipitated, the water flow passes through the water flow detector, and the water flow detector detects water pressure, flow speed, flow quantity and other information of the water flow. And the quality of the heat exchanger can be conveniently judged by workers, metal particles in water flow are reduced through the arranged filtering structure, and the influence of the metal particles on detectio
