In some embodiments of the present invention, as shown in fig. 1 and 3, a liquid level sensor 300 is disposed in each evaporation pan 100 except for the uppermost evaporation pan 100 to detect the water level in the evaporation pan 100, so as to control the heating capacity of the heating device 200.

In other embodiments of the present invention, a liquid level sensor 300 may also be disposed in the top evaporation pan 100 to detect the water level in the evaporation pan 100, so as to control the heating capacity of the corresponding heating device 200.

In some embodiments of the present invention, each heating device 200 is a condensing line 210 for circulating a refrigerant. The boat assembly also includes at least one bypass line 230.

At least one of the upper and lower ends of each support rod 410 is configured to be detachably coupled, such as by a screw, a socket formed in the evaporation pan 100, or a threaded hole formed in the evaporation pan 100.

A plurality of heating units 200 are detachably connected together, for example, each heating unit 200 is a condensing line 210 for circulating a refrigerant, and two condensing lines 210 adjacent to each other up and down are connected in series through the above-mentioned valve, so that the two condensing lines 210 are detachably connected. Alternatively, two condensing pipes 210 adjacent to each other up and down are connected in parallel.

The plurality of evaporation dishes 100 are detachably connected together through the connecting device 400, the plurality of heating devices 200 are detachably connected together, and when the evaporation dishes are produced, modular assembly can be realized on the evaporation dish assembly, so that the production efficiency is improved.

Alternatively, the overflow structure 110 includes a drain pipe 112 and an overflow port opened on a side surface of the corresponding evaporation pan 100, an upper end of the drain pipe 112 is connected to the overflow port, and a lower end of the drain pipe 112 is inserted into the water containing cavity of the evaporation pan 100.

Through setting up drain pipe 112, when the comdenstion water in the evaporating dish 100 of top or change the white water and flow into to the evaporating dish 100 of below, can avoid the water droplet splash, drip to the refrigeration refrigerating plant's of evaporating dish 100 outside the scope subassembly on, consequently the condensate water that significantly reduces and change the corruption of white water to refrigeration refrigerating plant improves refrigeration refrigerating plant's reliability and security, and then improves the holistic life of refrigeration refrigerating plant. By providing the drain pipe 112, two adjacent evaporating dishes 100 can be arranged in a staggered manner.
