板式熱交換器的傳熱機(jī)理：
板式熱交換器傳熱機(jī)理是根據(jù)傳熱機(jī)理是根據(jù)熱力學(xué)定律，“熱量總是由高溫物體自發(fā)地傳向低溫物體，兩種流體存在溫度差，就必然有熱量進(jìn)行傳遞”，兩種存在溫度差的流體在受迫對流傳熱過程中，由于熱傳遞板表面采用瓦楞波結(jié)構(gòu)優(yōu)化設(shè)計，其熱交換率達(dá)到92%,即使流體流速在雷諾準(zhǔn)數(shù)值以下，流體在板片之間的運(yùn)動亦呈三維運(yùn)動，促使流體形成劇烈紊動，減少邊界層熱阻強(qiáng)化傳熱效率。
The heat transfer mechanism of plate heat exchanger:Plate heat exchanger heat transfer mechanism is based on the mechanism of heat transfer is according to the laws of thermodynamics, the heat is always by high temperature object spontaneously to low temperature, two kinds of fluid temperature difference exists, is bound to have heat transfer ", exist two kinds of temperature difference of fluid in the process of forced convection heat transfer, due to heat transfer plate surface using corrugated structure optimization design, the heat transfer rate of 92%, even if the fluid velocity in the Renault must value the following, fluid movement between plates was also three dimensional motion, prompting form intense turbulent fluid, reduce the boundary layer thermal resistance improved heat transfer efficiency.
