[0004] After the workpiece is subjected to steam bath washing + vacuum drying, the surface temperature can reach 100℃. At this time, the high-temperature workpiece enters the cleaning tank with a temperature of only 40℃, which will inevitably cause the hydrocarbon solution in the cleaning tank to be greatly heated.

At this time, the condenser pipe works to cool the liquid in the cleaning tank, so that the temperature of the liquid in the cleaning tank is stabilized within a certain range.

[0006] However, the above-mentioned cooling method leads to a complex structure of the cleaning tank, and due to the size limitation of the cleaning tank, the heat exchange area is small and the cooling speed is slow. CONTENT OF THE INVENTION
