The plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Factors affecting the operation of the cooler
(1) System configuration. The plate cooler plays the role of heat conversion and follows the law of constant energy conduction (the heat released by the thermal measurement is equal to the heat absorbed by the cold measurement). The heat from the hot-side system is not taken away by the cold-side cooling water. If the amount of water is not enough and the water temperature is not enough, the hot-side temperature will not drop.
(2) The cause of the cooler itself. Many users only provide heat exchange area when purchasing plate coolers. They do not have specific data such as heat exchange volume, medium flow rate, and inlet and outlet temperature. As a result, although the plate coolers they purchased are of the right model area, the process combination Unreasonable, so the plate cooler did not meet expectations.
The water in the system and the demineralized water in the demineralization tank shall be strictly water-qualified, and they shall be injected into the pipe network only after they are qualified. When the new system is put into operation, the cooler should be separated from the heating system. After a period of time, the cooler should be integrated into the system to prevent impurities in the pipe network from entering the cooler.
