Plate heat exchanger in use, the user is generally concerned about two issues, heat transfer and pressure drop, heat transfer is the purpose of using plate heat exchanger, generally customers and manufacturers are more concerned about the problem, can generally meet, but the size of the pressure drop not only affects the normal use of plate heat exchanger, but also the entire system of operating costs have a great impact, so in the selection must pay attention to the plate heat exchanger pressure drop too high this problem.
In taking into account the heat transfer and pressure drop, can not rely solely on increasing the area to achieve, more to choose the right aspect ratio of the plate, the corrugated depth of different, different shapes of the corrugated corrugations, corrugated angle of different and different pitch of the corrugated plate to better achieve the perfect combination of heat transfer and pressure drop.
If you only rely on a small number of plate to meet all the conditions, certainly can not do the perfect combination of heat transfer and pressure drop, Qingdao RuiputeHeat Transfer Equipment Manufacturing Co., Ltd. has more than 400 kinds of plate, a variety of different aspect ratios; the same model has a variety of corrugated depth; zigzag corrugated, flat DC, horizontal corrugated, vertical corrugated and other shapes; the same kind of plate due to different corrugated angle, there are soft plate, hard plate points; corrugated Different pitch, etc. Through the special selection software to optimize the design, can be selected to meet the heat transfer requirements, but also the pressure drop can be the lowest plate.
Reasonable selection of plate heat exchanger can not only reduce the initial investment cost of equipment, can reduce the operating costs of equipment, Qingdao heating, for example, heating 141 days, a total of 3,384 hours of heating, such as the selection of suitable plate heat exchanger, so that the pressure drop is reduced, the circulating water pump power is reduced by 5KW, each year can save electricity 16,920 kilowatt hours, saving electricity costs 16,920 yuan.
Through the above analysis, in the choice of plate heat exchanger, not only to consider the initial investment in equipment costs, but also to consider the total cost of investment due to operating costs, including the inclusion of the investment period. Therefore, the plate heat exchanger pressure drop is very critical!
