Plate heat exchanger is composed of a series of metal plates with a certain corrugated shape. Thin rectangular channels are formed between the plates, and heat exchange occurs through the plates. The water-water plate heat exchanger is an ideal device for liquid and liquid-steam heat exchange. It features high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application range, and long service life. At the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of tubular heat exchangers, occupying one-third of the tubular heat exchanger's area, and the heat recovery rate can reach up to 90%;

Below is an introduction to the working principle used in the Shui Shui plate heat exchanger.

1. The working principle of the Shui plate heat exchanger is that many relatively thin copper plates are stacked in different structures within the plate heat exchanger. The inner layer contains high-temperature lithium bromide solution, and the other layer is high-temperature lithium bromide solution. In solutions with relatively low temperatures, a sealing ring is added in the middle, and the transfer of hot and cold media channels between adjacent cold and hot fluids during flow achieves cooling.

2. In this way, the water-water plate heat exchanger can better transfer heat through thin copper sheets, thereby achieving both the heating of low-temperature solutions and the reduction of high-temperature solutions, achieving a win-win cooling effect.

3. The working principle of the water-water plate heat exchanger can be understood as two relatively independent channels composed of multiple heat exchange plates, which respectively absorb refrigerant and heat medium, and efficiently utilize the heat transfer performance of the stainless steel plate. The heat from the hot side medium increases the heat from the cold side; In other words, the low heat from the cool-side medium is used to absorb heat from the hot side, thereby achieving the cooling effect.

4. Compared with traditional heat exchange equipment, the Shui Shui plate heat exchanger not only has advantages in appearance but also offers significant functional advantages: heat can be reused twice and resources can be fully utilized to achieve energy-saving functions. The principle of the previous tube-sheet crossing was the same, but the heat exchange effect was not as good as the water-water plate heat exchanger!
