    • The invention is a shell and tube type heat exchanger (10) that provides a greater heat transfer coefficient to pressure drop ratio. The invention includes a mini-vortex generator (36) on the surface of tubes (16) within the tube bundle (14) in the shell (12) of the heat exchanger (10). The mini-vortex generator (36) increases the heat transfer coefficient for grid baffle type heat exchangers having a longitudinal shell fluid flow without resulting in a significant increase in pressure drop. The invention also includes a sinuous-type grid baffle (18a) which permits a greater tube packing density and reduced pressure drop in a heat exchanger having longitudinal shell fluid flow. The invention also encompasses a shell and tube heat exchanger (10) having mini-vortex generators (36) and sinuous baffles (18a).

    • An improved fin array (30) for use in a heat transfer assembly, such as a condenser for a vehicle air conditioning system, and a method of making the improved fin array, are disclosed. The fin array comprises an elongated one-piece fin member (31) having top (32) and bottom (33) base portions with fin sets (34) extending between adjacent top and bottom base portions. The top and bottom base portions (32, 33) are generally flat for bonding to the heat exchanger tubes, such as by brazing. Each fin set includes a plurality of individual fins (35) extending generally perpendicularly to a longitudinal length of the fin member and having side edges (35e, 35f) that are longitudinally offset with respect to each other. The offset fin edges provide increased air flow over the individual fins and thus increase the efficiency of the overall heat exchanger. The fins may also be slightly bowed to accommodate for variation in the tolerances of the adjacent tubes. Additionally, the fins (35') may also have a slightly arcuate cross section to impart greater column strength to the fins contained within the improved fin array. The method of making the improved fin array includes a providing a flat sheet of elongated fin stock, pressing a chisel shape into the fin stock to a depth of between 40 to 90 percent of the thickness of the fin stock in order to produce a cut pattern along the length of the fin stock, bending the fin stock into a serpentine pattern, and then compressing the fin stock to finalize the one-piece fin member.
    • 公开了一种用于传热组件的改进的翅片阵列(30),例如用于车辆空调系统的冷凝器,以及制造改进的翅片阵列的方法。 翅片阵列包括具有顶部(32)和底部(33)基部的细长单件翅片构件(31),翅片组(34)在相邻的顶部和底部基部之间延伸。 顶部和底部底部部分(32,33)通常是平坦的,例如通过钎焊来结合到热交换器管。 每个翅片组包括大致垂直于翅片构件的纵向长度延伸并且具有相对于彼此纵向偏移的侧边缘(35e,35f)的多个单独翅片(35)。 偏置翅片边缘在单个翅片上提供增加的空气流量,从而提高整个热交换器的效率。 翅片也可以稍微弯曲以适应相邻管的公差的变化。 此外,翅片(35')还可以具有稍微弓形的横截面,以对包含在改进的翅片阵列内的翅片赋予更大的柱强度。 制造改进的翅片阵列的方法包括提供细长的翅片原料的平板,将凿子形状压入翅片坯料中至深度为翅片坯料厚度的40%至90%之间的深度,以便产生切割图案 沿着翅片坯料的长度,将翅片坯料弯曲成蛇形图案,然后压缩翅片坯料以完成整体式翅片构件。
