What is a brazed plate heat exchanger?

Brazed plate heat exchangers are assembled by stacking a series of metal plates with specific corrugated shapes and then brazing them together. Thin rectangular channels are formed between various plates for heat exchange. The heat exchanger is composed of thin metal plates pressed into a corrugated shape. Fluid flows through channels between the plates via meticulously arranged corner joints, with the cold and hot media always flowing in opposite directions in adjacent channels for heat exchange. Since the plate edges are brazed, the medium does not leak out of the equipment. The contact points of the brazed plate heat exchanger plates are also焊接 points to withstand the pressure of the medium.

Brazed plate heat exchangers are an evolution of removable heat exchangers, with the sealing material transitioning from gaskets to copper or nickel. All plates are bonded together using copper or nickel brazing. Just as all contact points on removable heat exchanger plates must be tightly sealed, all contact points on brazed heat exchangers must be fully brazed to ensure high heat exchange efficiency and pressure resistance, as well as a long service life.

2. Soldered Plate Heat Exchanger Advantages

Durable and highly corrosion-resistant. Made from SUS316 material sheets, either by copper welding or nickel welding. Offers superior corrosion resistance suitable for various fluids.

2. High-pressure resistance. The vacuum hard brazing process enables the plate heat exchanger to withstand a pressure of up to 45bar.

3. Excellent heat transfer performance. The specially designed plate pattern achieves higher heat transfer efficiency under both counterflow and parallel flow conditions.

4. High-temperature resistance. The hard-welded plate-type heat exchanger made of SUS316 material allows for operation at temperatures up to 200°C.

5. Compact, convenient, and lightweight. The rigid plate heat exchanger is even more compact and convenient than the shell-and-tube type; it's about 1/5 the size of the shell-and-tube, yet offers the same heat transfer capacity. Plus, it's easier to install and replace.

6. Low maintenance costs. The specially designed plate patterns are perfectly suited for turbulent heat transfer conditions, eliminating the need for special and frequent maintenance costs.
