The main advantages of PHE

The plate heat exchanger (PHE) has been highly developed since the new era. It has been widely applied to various industries due to its high efficiency, energy saving and environmental friendly.
The main advantages of PHEs are listed:
1: High efficiency and low heat waste
The heat exchanging rate could reach its peak of 6000W/m2K under the best condition and 3000-4000W/m2K under general conditions, which is 3 to 5 times than shell and tube heat exchangers. There are no shunts in PHE so that all the liquid flows in turbulence with plate waves and exchanges the heat adequately. The heat exchanging area is only 1/3 to 1/4 of that in shell and tube heat exchangers during the same heat exchanging process.
2: Less area occupied and lighter weight
PHE has no requirements to extra space except its own. The thickness of plate for PHE is only 0.6 to 0.8mm. The occupied area and weight is 80% less than shell and tube heat exchangers.
3: Low fouling ratio
The advanced design for PHE avoided the blind section which causes inadequate turbulence. With advanced design the fouling is difficult to exist. This technique guarantees good heat exchanging behavior.
4: convenient repair and cleaning
The plates of PHE are assembled with fastened bolts. When the plates need cleaning, we just loosen the fastened bolts to dismount.
5: Broad adaptability
    The equipment can work under 180℃ and 2.0MPa pressure and be adapted to heating, cooling, heat recycling, condensing, food sterilization, etc. It has obvious economic efficiency in low end heat recycling. The plates can adapt to corrosively conditions, too.

Safety Considerations for Plate Heat Exchanger Design

图片
Hofmann During the process, there are some safety considerations you should notice: 1. Design specifications. The design specifications of heat exchangers include the types of working fluid and flow, import and export temperature, working pressure and heat exchanger efficiency. Aerospace heat exchangers should also include permissible pressure drop, size and quality. 2. Overall arrangement. First you should choose the type and structure of heat exchangers, the form of fluid flow and the materials, and then choose the type of heat surface, to consider the operating temperature and pressure, etc. 3. Heat design. The thermal design of the heat exchanger includes heat transfer calculation, flow calculation and determination of size. In addition to technical performance indicators, thermal design also need heat transfer characteristics (including heat transfer characteristics, flow characteristics and structural parameters) and fluid and material thermal activity p...

Plate Heat Exchanger 2.1 Improve heat transfer efficiency Plate heat exchanger is a wall-type heat transfer heat exchanger, hot and cold fluid are transferred through the heat exchanger plate, fluid and plates are directly in contact with each other, and the heat transfer mode is conduction and convective heat transfer. The key to improve the heat transfer efficiency is to improve the heat transfer coefficient and logarithmic mean temperature difference 。 1). Improving the heat transfer coefficient of the heat exchanger is at the same time to improve the heat and heat on both sides of the plate surface heat transfer coefficient, reduce the thermal resistance of the dirt layer, choose high thermal conductivity of the plate, reduce the thickness of the plate in order to effectively improve the heat transfer. a. Improve the surface heat transfer coefficient of the plate Since the ripple of the plate heat exchanger can make turbulence of the fluid at a small flow rate...

Hofmann heat exchanger There are many dense pipes in the milk production workshop! Some of these pipes are cold water, some are steam, and some milk, and milk is in the complex flow of the pipeline system! Use a heat exchanger for heating. A heat exchanger generally has two channels, one is for milk flowing, the other is for heating or cooling medium through. The heating or cooling medium is usually steam or cold water. During the convection process of steam or cold water and milk, provide heat to milk, or take away the heat from the milk to achieve the purpose of heating or cooling. There are many kinds of heat exchangers. Plate Heat Exchanger Tubular Heat Exchanger Snake-like Heat Exchanger                                                                        ...
