Description
Technical Field
The invention relates to the field of plate heat exchangers. More specifically, the invention relates to a heat exchanger plate pack for a plate heat exchanger and a plate heat exchanger.
Background
The plate heat exchanger is the most commonly used heat exchanger in the refrigeration field, for example, in air conditioning refrigeration, refrigerant in staggered and isolated flow channels inside the heat exchanger evaporates and absorbs heat to cool the medium B. In the process, if the evaporation temperature is too low or the flow of the medium B is locally too low, the crystallization phenomenon is easily generated inside the heat exchanger. Once the heat exchanger crystals break the heat exchange fins, the refrigerant and the medium B have blowby. The skilled person has also implemented many measures in order to reduce the possibility of crystallization inside the heat exchanger. Such as increasing the evaporation temperature of the refrigerant. And a temperature sensing probe is arranged at the side outlet of the medium B, and when the temperature of the detected medium B is close to the freezing point, the flow of the refrigerant is reduced or the flow of the medium B is increased. When the unit is stopped, the medium B side is emptied as much as possible so as to prevent the medium B side from crystallizing due to too low ambient temperature.
However, the above measures cannot completely prevent the crystallization inside the plate heat exchanger. When the inner part of the heat exchanger is just leaked, the common plate heat exchanger cannot observe any sign from the outside. When the medium B enters the refrigerating system, irreversible damage can be caused to equipment in the refrigerating system, and the loss is extremely large.
Through years of statistical analysis, 80% of internal crystallization breaking points of the heat exchanger are positioned at a fillet runner at the lower end of the heat exchanger. The medium B side flow speed is slow when the refrigerating system operates, and the temperature of the medium B is easy to drop to the freezing point for crystallization. After the system is shut down, the accumulated liquid at the position cannot be completely discharged, and when the environmental temperature is too low, crystallization is easy to occur.
