Heat transfer plate for core parts of heat exchanger

Heat exchangers usually use water as the cooling medium. Most of the plates are made of stainless steel thin plates. The corrugated flow tips are pressed on the plates. The space between two adjacent plates is the medium flow channel. The cold and hot fluids are in the two plates. When side flow, heat exchange is carried out through the plates.

The special flow channel formed by the corrugation makes the fluid turbulent under the condition of extremely low flow rate. The turbulence under the low Reynolds coefficient has its own descaling effect, which effectively destroys the insulating boundary layer and reduces the thermal resistance of the liquid film on the interface. In general, the heat transfer coefficient K value of the plate heat exchanger is in the range of 3000-6000W/m℃. At the same time, the two media flow almost completely countercurrent, and the heat transfer efficiency is high.

After the plate heat exchanger is used for a period of 1-2 years (depending on the actual operating conditions), necessary disassembly, cleaning, and pressure testing are required. The plates that have problems such as deformation or perforation need to be replaced in time. During this process, the assembly of the heat sink must be arranged in strict accordance with the flowchart.

The heat exchanger accessories are designed according to the cooling process, and the plates can be connected in parallel or in series. Therefore, there are common single-process and dual-process heat exchangers. The heat and cold media will be fixed on the vertical axis of the plate and arranged on one side. At this time, the same medium will be on the left or right at the same time.
