Application of plate heat exchanger in chiller

  Plate heat exchangers have played a decisive role as one of the four major components of industrial chillers. The chiller is a water cooling device Application of plate heat exchanger in chillerthat provides constant temperature, constant current, and constant pressure cooling equipment.The principle of the chiller is to inject water into the internal tank of the machine and cool the water through the chiller refrigeration system. Then, the water pump inside the machine injects the low-temperature frozen water into the equipment to be cooled, the chilled water takes away the heat inside the machine, and the hot water is returned to the water tank for cooling, so that the cooling is performed in a cycle to cool the equipment.

  Depending on the customer's use, some industrial chillers use plate heat exchangers. It is a high- and compact heat exchanger with corrugated sheets as heat exchange surfaces, and has been widely used in cold water refrigeration equipment.The plate heat exchanger has the advantages of simple structure, easy handling and installation, regular cleaning or replacement of the plates, and flexible heat exchange adjustment.

  A plate heat exchanger for an industrial chiller is composed of a plurality of plates, and the corrugations of adjacent plates are opposite in direction.The liquid flows along the narrow curved passage between the plates, and the speed and direction are constantly mutated, and the vibration is strong, thereby greatly enhancing the heat transfer effect.The plate heat exchanger for industrial chillers is divided into two structural forms, one is bolt-tight and the other is brazed. The bolt-tight pressure bearing capacity can reach 2~2.5MPa; the brazed heat exchanger is made of 99.9% pure copper overall vacuum welding, and the bearing pressure can reach 3MPa.
