Technical properties of heat transfer plates for spiral plate heat exchangers
On the spiral plate heat exchanger heat transfer plate by using heat transfer plate, stainless steel sheet with respect to its material will choose or titanium plate, in the 10000 tons of spiral plate heat exchanger dedicated hydraulic press to a compacting above, at this point, can avoid the repeated stamping, plate punching time is conducted using double oil film coating technology, to ensure the plate forming precision is high.
, spiral plate heat exchanger on the plate in the production, in this thinning quantity also is must pay attention to should be controlled in a 0.1 mm, the mould for the composite mould clamping, at this point, is referring to the mold should be composed of several small mold assembly, so that can ensure uniform plate stamping molding stress at the same time, in which there is a one piece mould wear can be quickly replaced, ensure the accuracy of the mold.
During the design of the plates on Murphy's spiral plate heat exchanger, the numerical simulation technology of ultra-fine grid is also adopted to combine with the precise experimental measurement method to design the heat exchange plates with excellent flow and heat transfer performance. After that, high turbulence and high heat transfer coefficient can be generated when the plate on the spiral plate heat exchanger is at low flow rate. Under a certain heat transfer coefficient, the plate has a smaller resistance coefficient.
As many as thousands of contact points are formed between the plates by the "man" shaped corrugated plates. The pressed plates have relatively high precision, which makes the contact points between the plates even, and can withstand pressures of up to 25bar or more at this time.
Spiral plate heat exchanger device of relatively high coefficient of heat transfer, with the characteristics of high efficiency and energy saving, is due to the liquid into the plate heat exchanger plate, turbulence can appear very developed, the formation of turbulence and support the contact between the plate has a very close relationship, many support contacts to make heat exchanger heat transfer capacity was improved, also strengthened on bearing capacity and stiffness of the slab is also good, long service life.
