Working principle and characteristics of high-efficiency intelligent plate heat exchanger units

High-efficiency intelligent heat exchanger unit principle: After filtration and purification, the secondary water enters the heat exchanger through a circulation pump and is heated by steam or high-temperature water to provide heat. After entering the plate heat exchanger, the steam or high-temperature water becomes condensate or high-temperature return water and returns to the heat source. In the secondary heating system loop, the supplementary water pump will drive the demineralization. Water is injected into the system to maintain constant system pressure.

What are the advantages of plate heat exchangers?

What are the advantages of plate heat exchangers? The main reason for their popularity is that they are easy to clean, lightweight, have a small footprint, and are inexpensive, making them popular in many industries. The ease of cleaning is due to the fact that the tightening plates of the plate heat exchanger can be removed, allowing the plate pack to be loosened and the plates removed for mechanical cleaning. Modifying the heat transfer area or flow arrangement only requires adding (or removing) plates to achieve the desired increase (or decrease) in heat transfer area.

Tips to improve the efficiency of plate heat exchangers

When using plate heat exchangers, how can we improve their efficiency? Let's introduce four tips to improve their efficiency. 1. Improve the surface heat transfer coefficient of the plates. Because corrugation can cause turbulence in the fluid at a lower flow rate (Reynolds number -150), a higher surface heat transfer coefficient can be obtained. The surface heat transfer coefficient is related to the geometric structure of the plate corrugation and the flow state of the medium.

Tips to improve the efficiency of plate heat exchangers

Since ripples can generate turbulence in fluids at lower flow rates (when the Reynolds number is approximately 150), a higher surface heat transfer coefficient can be obtained. The surface heat transfer coefficient is related to the geometric structure of the plate ripples and the flow state of the medium. The shapes of the plates include herringbone, straight, and spherical, etc.

What are the advantages of plate heat exchangers?

Cleaning and convenience. After removing the pressure plate of the plate heat exchanger, the plate bundle can be loosened, the plates removed, and mechanical cleaning performed. Simple modifications to the heat transfer area or flow combination only require adding (or reducing) plates to achieve the desired increase (or decrease) in heat transfer area. Lightweight. The plate thickness of the plate heat exchanger is only 0.6~0.8mm, while the heat transfer tube thickness of the shell and tube heat exchanger is 2.0~2.5mm; the shell of the shell and tube heat exchanger is much heavier than the structure of the plate heat exchanger. Under the same heat transfer mission, the plate heat exchanger requires a smaller heat transfer area than the shell and tube heat exchanger.
