Intelligent dual threaded pipe heat exchanger unit: This product uses a three-dimensional spiral tubes efficient micro unit, the tubes outer wall corrugated spiral structure. Heat transfer fluid through the spiral corrugated pipe when the inner and outer wall, away from the wall to maintain the original part of the flow state, close to the wall section was changing the speed and size of the spiral movement, this part of the spiral motion of the fluid at the same time changing the fluid away from the wall flow state, the interaction between the two, both inside and outside the tube to form a rapidly changing speed, size, direction, form a complex mixture of three-dimensional flow. 1. sided turbulence, double reinforced single-phase fluid in the tube inside and outside for three-dimensional flow spiral, was turbulent, turbulent flow and thinning of the wall continue to disrupt laminar boundary layer, reduce resistance and improve internal and external heat transfer coefficient of the tube, dual heat transfer enhancement. Phase change due to the three-dimensional fluid side corrugated spiral helix structure effectively cut off condensate film, does not result in a large area along the wall of the condensed film formation and thickening, thereby reducing condensation side resistance and improve the heat transfer coefficient of heat transfer enhancement. 2. Reduce pollution resistance, difficult to scale because of the special structure of the three-dimensional spiral tubes, the degree of turbulence greatly enhanced fluid, the fluid in the tubes form a vortex wall. High-speed erosion wall, so that the dirt is difficult to adhere to reduce fouling resistance, easy to scale, long-lasting effect of heat transfer efficiency. 3. Compact, stable operation of the product due to increased heat transfer coefficient, so pass the same heat transfer, reduce the required heat transfer area, smaller dimensions, and therefore less area. From a structural point, this product uses a fixed tube sheet structure, no moving parts, by a significant reduction in the thermal impact, integrated product life and operating cost analysis, cost-effective products of high mandatory supervisory inspection, quality and reliable. Features: 1. The mechanical and electrical equipment together, compact, small footprint 2. The system uses the frequency or expansion tank water control, automatic replenishment 3. steady load, low noise, reliable performance, low maintenance 4. Intelligent control, easy operation 5. High heat efficiency, long life 6. decontamination with automatic cleaning function, failure rate.
