Plate heat exchangeris widely used in people's life.Plate heat exchangeris one of the most widely used devices in heat transfer equipment. It has the characteristics of high heat transfer efficiency, compact structure, small floor area, installation, maintenance, and convenient combination. It is widely applied to electric power, petroleum, chemical industry, metallurgy, machinery, light industry, food, medicine, electric power, painting, ship, electromechanical, textile, papermaking, heating and other industrial sectors. A good plate heat exchanger has a good heat transfer effect, and the service life is also very long.
What is the heat transfer mechanism of theplate heat exchanger:
1, the heat transfer mechanism ofplate heat exchangers is based on the law of Thermodynamics: according to the heat transfer mechanism, "heat is always transferred from high temperature objects to low-temperature objects, and two kinds of fluids have temperature difference, so they must have heat transfer."
2, there are two kinds of fluid temperature difference in forced convection heat transfer process, the heat exchanger heat transfer plate surface using wave structure optimization design of corrugated board, the heat exchange rate of 92%, even if the fluid velocity in the Reynolds numerical, fluid movement between the boards was three dimensional motion, prompting the formation of intense fluid the turbulent boundary layer, reduce the heat transfer efficiency of heat resistance.
