The grid design of spiral plate heat exchanger has advantages
For spiral plate heat exchanger upper pieces of imported triage area has the flow guide groove design, this kind of spiral plate heat exchanger will also have closer to the role of the difference in different flow channel the flow resistance of above, on the one hand, also can make the fluid distribution in plate heat transfer area evenly, after also can avoid the uneven flow distribution and flow blind Angle in thermal efficiency brought by the decline, pitting corrosion and scaling, etc.
Murphy experts designed the plates with large width on the helical plate heat exchanger equipment, and increased the pressure equalizing groove along the isopotential line, so that the resistance formed by the intersection of the streamline guide groove and the isopotential line equalizing groove was relatively small, and the grid-shaped inlet shunt zone had nearly perfect flow equalizing effect.
At the same time, the splitter zone on the spiral plate heat exchanger also plays a role of rapidly forming turbulent flow and intense heat transfer, which will make the splitter zone participate in the heat transfer in advance, and in this regard, it can effectively improve the length of the heat transfer time and reduce the heat transfer area.
In addition, for the disadvantages of flow design adopted by ordinary plates, if the cold medium enters and leaves the plate from the left side at the same Angle, it will be under the effect of short circuit, and the cold medium will easily form turbulent efficient heat transfer zone on the left side of the plate, while the flow dead zone on the right side will be easily formed. When the hot medium enters and exits the plate from the right side, it is easier to form turbulent efficient heat transfer zone on the right side of the plate under the short-circuit effect, while the dead zone on the left side is easy to form. Make the heat transfer effect worse.
Spiral plate heat exchanger in the plate suspension positioning and locking system, that is, will have the function of suspension, the plate suspended on the upper guide rod, so that it can slide freely along the upper guide rod before and after; The plate suspension positioning and locking system in spiral plate heat exchanger will have the characteristics of positioning, which will make the plate positioning accurate; Later also has the lock effect, can ensure that it never dislocation.
