2.Design and Selection
The plate heat exchanger produced by our company strictly follows the rule listed in GB16409-1996 "plate heat exchanger," to design, manufacture and test.
3. Overview
Plate heat exchanger is compact and efficient heat exchange equipment, using the metal corrugated sheet as the major heat transfer agent. The fluid flows through the inner-flow mesh panel which is made up by the corrugated plates. Because after the plates assembly, they form a special channel which can generate turbulence under low Reynolds number, and the turbulence can easily destroy the fluid boundary layer,that greatly reduces thermal resistance and efficiently enhances the heat transfer, moreover, with no scale.
According to the channel width of the hot fluid flow and the cold fluid flow, the channel can be divided into two types:BR and BRB.
On the ground of the flow rate, temperature range condition and process condition, the plate heat exchanger can be assembled into single pass or multi pass type. When the media's temperature range is 1.8 times bigger than the LMTD (log mean temperature difference), it should apply the multi pass. In the other hand, when the flow rate's fitness value is 0.3 ~ 0.5m/s or the flow rate is too slow, it should apply the dual flow or multi flow.
