Introduction:
Shandong Wintech plate heat exchanger is a kind of heat exchanger formed by pressing thin metal plates into heat exchange plates with certain corrugated points, then stacking them and transferring them with rack plates and clamping bolts. The working fluid flows in the narrow and tortuous channel formed between the two plates, and the hot and cold fluid flows through the channel plates between the plates for cold and heat exchange.
Advantage:
1. The core of the heat exchanger is a fully welded plate, and the blind plate is connected by a nut. The equipment can be quickly installed, disassembled and cleaned easily;
2. Oblique corrugated symmetrical channel, turbulent heat transfer efficiency is higher;
3. The combination of wide and short channels is suitable for working conditions that are easy to block;
4. It occupies a small area and can be installed vertically or horizontally.
5. A wider range of applicable fluids
The size of a plate can range from a few square centimeters (100 mm x 300 mm side) up to 2 or 3 square meters (1000 mm x 2500 mm side). The number of plates in a single exchanger ranges from just ten to several hundred, so reaching surface exchange areas up to thousands of square meters.
The figure shows the flow of fluids inside the exchanger. Fluids are divided into several parallel streams and can produce a perfect countercurrent.
Plate and Frame Heat Exchangers
In the PHE the plates create a frame where the plates are pressed with headers and tie bars, and the seal is guaranteed by gaskets. Gaskets, in addition to their sealing effect, serve to direct the flow of the fluids, and are placed along the grooves at the edges of the plates.
The maximum temperatures used for sealing heat exchangers are between 80°C and 200°C while pressures can reach 25 bar.
Gaskets are available in various types of butyl or silicone rubber.
The main characteristics of these types of heat exchangers are:
- quick and easy dismantling for cleaning and control operations
- adaptation to variable operating conditions by adding or removing heat plates to modify the installed thermal flow
- any fluid leaks due to non-perfect sealing of the gaskets do not contaminate the other fluid but are directed away
- materials that are poorly adapted to soldering, such as titanium, may be used
- the gaskets limit the maximum pressure and temperature values
- potentially high costs due to the design of moulds, presses and all the production process
- high cost of the gaskets
