摘　　要：针对我公司新开发的某型低温液体运输车运用自增压原理进行卸车,用常规的翅片式增压器进行设计需要的空间大,汽化量不足;因此对此类产品进行了增压器结构的改型,将其结构改为绕片式结构,但绕片式增压器的计算用普通换热方式进行计算特别复杂,计算误差较大;本文对该类产品运用热力学第三定律对其换热的面积进行计算校核,简化计算过程,并且根据实际使用情况得到相应的修正系数,计算出的结果能够实际满足需要。In view of the development of the new company for a certain type of cryogenic liquid transport vehicle using self pressurizing principle for truck, with conventional fin type supercharger design needs a large space, insufficient vaporization; therefore for such products of turbocharger structure improvement, its structure is changed into a winding type structure, but the winding type supercharger calculation of common heat transfer calculation is particularly complex, large calculation error; the product using the third law of thermodynamics on the heat transfer area calculation, simplified calculation process, and according to the actual use of corresponding correction coefficients, calculated results can meet the need of practical.
