What is the working principle of zirconium heat exchanger

The working principle of zirconium heat exchanger is similar to that of ordinary heat exchanger. It is mainly based on the principle of heat transfer. The fluid is heated or cooled by exchanging heat between fluids of different temperatures. Common zirconium heat exchangers include shell and tube type, plate type and other structural types. Their working principles are as follows:
Shell and tube zirconium heat exchanger:
Heat exchange process: This type of zirconium heat exchanger has a shell, in which many zirconium tubes are arranged. The hot fluid and the cold fluid flow in different channels respectively. The hot fluid flows in the tubes, and the cold fluid flows in the shell side (i.e. the space outside the tubes). Since zirconium material has good thermal conductivity, heat will be transferred from the hot fluid to the cold fluid through the tube wall of the tube. The high-temperature hot fluid transfers heat to the tubes, and the tubes transfer heat to the surrounding cold fluid, so that the temperature of the cold fluid increases and the temperature of the hot fluid decreases, thereby realizing heat exchange.
Heat transfer enhancement measures: In order to improve the heat exchange efficiency, some shell and tube zirconium heat exchangers will be improved in structure, such as setting spiral grooves on the outer wall of the tubes. These structures can make the flow of cold fluid in the shell more turbulent, increase the contact area and contact time between the cold fluid and the tubes, and thus improve the heat transfer effect.
Plate zirconium heat exchanger:
Heat transfer method: The plate zirconium heat exchanger is composed of a series of corrugated zirconium thin plates superimposed on each other, and complex flow channels are formed between the plates. The hot fluid and the cold fluid enter different flow channels respectively, and the two fluids flow between adjacent plates. Heat is transferred from the hot fluid to the cold fluid through the zirconium plates to achieve heat exchange. Since the thickness of the zirconium plates is very thin and the corrugated shape increases the disturbance of the fluid, the plate zirconium heat exchanger has a high heat transfer efficiency.
Fluid flow characteristics: When the fluid flows in the flow channel of the plate heat exchanger, it is blocked and guided by the plates, and the flow speed and direction are constantly changing, forming a complex flow field. This flow state is conducive to heat transfer and enables the fluid to fully exchange heat.
