Removable Plate Heat Exchanger

The removable plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is performed through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid, liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, convenient installation and cleaning, wide application and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the shell-and-tube heat exchanger, and the floor area is one-third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90%.

Features of removable plate heat exchanger

1. High heat transfer coefficient

The design of the plate corrugation aims at a high thermal conductivity of the film, and the fluid can generate a strong turbulent flow at an extremely low flow rate. Generally speaking, the heat transfer coefficient K value of the plate heat exchanger is 3000-6000W/m2 · Within the range of °C.

2. Low cost

Under the premise of the same heat transfer, the metal consumption is low, the floor area, fluid resistance, cooling water consumption and other items are reduced, which greatly reduces the investment cost.

3. Small heat loss

Due to the compact structure and small volume, the outer surface area of the heat exchanger is also small, so the heat loss is also very small, and the equipment generally does not need insulation.

4. Compact structure, easy maintenance

A small space can be combined with a large heat exchange area, and the equipment itself can provide maintenance space without additional disassembly space.

5. It is conducive to the utilization of low-temperature heat sources, safe and reliable in use, and flexible in combination
