Ship fan evaporator using hot air to melt frost

At present, the conventional ship fan evaporators use hot air to melt frost, a ship keeps inclination sailing during a period due to waves, and then water gathered in a water holding disc cannot be drained completely, an ice layer will cover the water holding disc after a few of frost melting cycles, the drainage opening will be blocked, and a frost melting system will fail. The ship fan evaporator is different from the conventional an evaporators using hot air to melt frost, and is characterized in that a plurality of seamless tubes as heating coils are arranged under a water holding disc according to the area of the water holding disc, the heating coils heat the water holding disc during a frost melting process all the time so as to prevent frost molten water from freezing, and the frost molten water can be smoothly drained out from a drainage opening. 目前，应用于船上的风机蒸发器如果采用热汽融霜方式进行融霜，由于浪的作用而使船在段时间保持个倾角航行，这就会导致接水盘中积水排不干净而结冰，几个融霜循环下来，冰层就会覆盖接水盘，并堵塞排水口，从而融霜系统失效。本设备与普通热汽融霜的风机蒸发器不同的是，其接水盘的下面根据接水盘的面积设置了些无缝管作为加热盘管。在融霜
