Gradient utilization multi-flow plate heat exchanger

The utility model discloses a gradient utilization multi-pass plate heat exchanger which comprises a fixing plate, and a first medium inlet is fixed to the left side face of the fixing plate through bolts. A second medium outlet is fixed to the rear side of the first medium inlet in the left side face of the fixed plate through a bolt, a movable plate is arranged on the right side of the fixed plate, a first medium outlet is fixed to the right side face of the movable plate through a bolt, and a second medium inlet is fixed to the front side of the first medium outlet in the right side face of the movable plate through a bolt. According to the gradient utilization multi-flow plate type heat exchanger, two threaded rods rotate at the same time through a rocker and a first belt pulley, so that the threaded rods drive a movable plate to move, the effect of clamping a heat exchange plate is achieved, and the situation that the heat exchange plate is broken or the heat exchange effect is affected due to the fact t
