The heat transfer efficiency is good. Curved spiral channel and spacer columns , help enhance the small turbulent fluid in the fluid passage resistance can be improved design flow rate, help to improve the heat transfer coefficient. For water - water heat transfer , the heat transfer coefficient can reach 1.8 to 3.5 kilowatts per square meter per degree Celsius kW/(m( ·℃ ) . With self-cleaning function, when the fluid in a single channel passes through the impurity deposits in the channel, the flow rate will change Relatively improved, it is easy to wash away impurities. The non-detachable structure has good sealing performance. It is suitable for the heat exchange of precious fluids.
