Evaporator according to different thermal conductivity materials is different, according to the thermal performance from high to low, namely, silver, copper, aluminum, steel. However, using silver for heat sinks is too expensive. The best solution is copper. Although aluminum is much cheaper, it is clear that thermal conductivity is not as good as that of copper (about 50% copper), but stainless steel tube evaporators is used for some specific environmental conditions.
Advantages of Stainless steel tube evaporator
There are many types of stainless steel tube evaporator in the market, stainless steel - aluminum evaporator, stainless steel - copper - aluminum composite evaporator, stainless steel plate evaporator and stainless steel decorative evaporator
Stainless steel evaporator is to play the metal's own natural corrosion resistance, and fundamentally solve the problem that can not be solved by other products, it is worth recommending is its environmental protection, without internal corrosion and formaldehyde containing coating on thebody without hazard, high pressure capacity, long service life.
Disadvantages of Stainless steel tube evaporator:
Low heat dissipation, from the thermal conductivity point of view, copper 0.94, pure aluminum 0.53, aluminum alloy 0.37, cast aluminum 0.33, 0.16 steel, cast iron 0.12, stainless steel 0.05, stainless steel cooling efficiency is too low.
