Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.

主要做了以下几方面的试验研究工作：(1)对不同翅片形状、管径大小、翅片管排列方式，以及是否带波纹等结构参数对蒸发器传热系数的影响进行了比较分析，得出在不结霜工况下，具有最高传热系数的蒸发器结构是圆翅片小管径正三角形排列等节距结构的结论。

The vertical shields are now lower at the front (yellow dotted line indicates previous shape) and the small horizontal fin has been extended rearwards, so as to better direct and split in two the airflow exiting from beneath the front wing.

垂直保护片前部现在更低（黄色虚线显示以前的形状），小水平翼被延伸到后方，这就能更好的疏导和分流前翼下方的气流。

Heat transfer performance of a plate-fin recuperator was studied experimentally and numerically in this paper.

对板翅式回热器的传热性能进行了实验和数值模拟，对板翅式回热器的传热性能以及其温度场和速度场的情况进行了分析，为今后的此种换热器的设计与改进提供了一定的理论依据。

The results indicate that in the present research range of renumber and constructional paraments, the enhanced heat transfer capability of the pin-fin with gap is not obvious, and the pressure drop is taller than that of no gap.

计算结果表明：在本文的参数范围内，与完整扰流柱相比，分离结构扰流柱的换热效果略有增强，而阻力系数随之增大，分离位置居中的扰流柱通道的换热效果最好。

Other baleen whale s are the blue, fin, gray, humpback, and sei whale s and the rorqual.

其它的须鲸有蓝鲸、鳍鲸、灰鲸、驼背鲸、鳕鲸和鲸。

Function always comes first with Caleido: the creation of radiators that emit the maximum amount of heat takes priority over fussy designs. Danilo Rossetti founded the family-run brand in 1933. It is party of parent group Co.ge.fin.
