The heat exchange area of brazed plate heat exchanger consists of a thin metal plate which is stamped into corrugated shape. Fluid flows through channels between plates through carefully arranged corner interfaces. Refrigerant and heat medium always flow in opposite directions in adjacent channels for heat transfer. Because the edge of the brazed plate heat exchanger is welded, the medium will not flow out of the equipment.
Compared to traditional brazed plate heat exchangers, brazed plate heat exchangers have high heat transfer efficiency and are very compact and can be easily installed in limited space locations, thereby reducing the number of parts throughout the system, saving operating costs and bringing greater benefits to customers.

Brazed plate heat exchangers - specific steps for cleaning scale
1) Washing: before pickling, the heat exchanger is first washed open, so that there is no mud, scale and other impurities in the heat exchanger, which can not only improve the effect of pickling, but also reduce the acid consumption of pickling.
2) Pour the cleaning liquid into the cleaning equipment, and then inject it into the heat exchanger.
3) pickling: the heat exchanger filled with acid solution is statically soaked for 2h, and then the continuous dynamic cycle is 3 ~ 4h, during which the positive and negative alternating cleaning is carried out every 0.5h. After pickling, if the pH value of the acid is greater than 2, the acid can be reused, otherwise, the acid washing solution should be diluted and neutralized and removed.
4) alkali washing: after the end of pickling, NaOH,Na3PO4, softened water is prepared in a certain proportion, and the heat exchanger is alkali washed by dynamic cycle to achieve acid-base neutralization, so that the heat exchanger plate is no longer corroded.
5) Water washing: after alkali washing, wash the heat exchanger repeatedly with clean softened water for 0.5h, and rinse the residue in the heat exchanger thoroughly.
6) Record: In the cleaning process, the time of each step should be strictly recorded to check the cleaning effect.
