In the development course of heat exchanger, spiral plate heat exchanger occupies a very important position.and the spiral plate heat exchanger as a typical heat transfer equipment, heat Exchange station has very important significance.
The advantage of spiral plate heat exchanger is obvious compared with other heat exchangers:
1, Under normal conditions, the heat transfer coefficient of the spiral plate heat exchanger is large, the space occupied by small size, compact structure and reasonable design, easy maintenance.Under the condition of equal heat transfer, the space occupied is only 1/2 to 1/3 of the shell-and-tube heat exchanger.
2, at the same time in the installation, there is no need to reserve too much space. For the spiral plate heat exchanger, only need to loosen the clamping screw, you can in the original space within 100% contact with the surface of the heat exchanger plate, easy disassembly, easy to clean.
Small size, light weight, easy to install in small space.
In addition to these, the spiral plate heat exchanger has the following advantages: The first advantage is that the temperature difference is very small. This is because the heat transfer coefficient of the spiral plate heat exchanger is large, coupled with strong turbulence effect, in the heat exchanger after the flow of heat, can make heat exchanger secondary hot water temperature difference is very small, sometimes the temperature difference can reach near 1℃~3℃.
This can make the thermal efficiency greatly increased, improve the economy of heat exchanger equipment. The second advantage is that the heat loss is very small.
In practical application, the heat transfer loss of the spiral plate heat exchanger is only one-fifth of the shell-and-tube heat exchanger, while the weight is less than half of the tube-shell type. Third, the spiral plate heat exchanger adaptable, widely used, so far, has been in the chemical industry, machinery, cement, petroleum, electricity, hot water heating and other engineering fields have a wide range of applications. In short, the spiral plate heat exchanger with high heat transfer efficiency, small size, light weight, easy disassembly and other advantages.
