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。
For our newly developed type of cryogenic liquid transport vehicles using self-pressurization principle of unloading, with conventional fin-type turbochargers to design the space required for large, less than the amount of vaporization; so for such products supercharger Structure of the modified, the structure changed to the winding structure, but the winding turbocharger calculation using ordinary heat exchange method is particularly complicated, the calculation error is greater; this article on the use of the third law of thermodynamics The heat exchange area is calculated and checked, the calculation process is simplified, and the corresponding correction coefficient is obtained according to the actual usage, and the calculated result can actually meet the needs.
