Flat coil tube is a highly compact heat exchanger applicable in refrigeration, food processing, heat recovery, power generation and many other systems. Flat coil tube is zero height equipment (compared to the normal helical tube) which makes it very appropriate for heat extraction from the hot zone area of the solar ponds. In this research, a validated numerical study is carried out to evaluate the thermal, frictional characteristics of flat coil tube with spring inserts. The proposed sort of turbulator is the only practicable turbulator for curve-shaped heat exchangers. The Nu number of flat coil tube heat exchanger doubles or triples with spring inserts (depending on geometry of the turbulator). It means that, in the same level of desired heat transfer capacity, the flat coil tube with spring inserts is more compacter (one third smaller size/weight) compared to the plain coil tube. For some purposes such as aerospace science, the size and weight of the heat transfer equipment is crucial as they are indicators of fuel consumption and cost of the implementations. As spring turbulator affects both heat transfer coefficient and hydraulic diameter (effective factors on Nu number), higher heat transfer coefficient does not necessarily mean higher Nu number. Other memorable graphical, quantitative, and qualitative results are observed for this system all of which are reported in this paper.

扁平盘管是一种高度紧凑的换热器，适用于制冷、食品加工、热回收、发电等许多系统。扁平盘管是零高度设备（与普通螺旋管相比），非常适合从太阳能池的热区提取热量。在这项研究中，进行了一项经过验证的数值研究，以评估带有弹簧嵌件的扁平螺旋管的热摩擦特性。所提出的湍流器是唯一适用于曲线形热交换器的湍流器。怒族_带弹簧插件的扁平盘管换热器的数量增加一倍或三倍（取决于湍流器的几何形状）。这意味着，在所需传热能力水平相同的情况下，带弹簧插件的扁平盘管比普通盘管更紧凑（尺寸/重量小三分之一）。对于航空科学等某些目的，传热设备的尺寸和重量至关重要，因为它们是燃料消耗和实施成本的指标。由于弹簧湍流器影响传热系数和水力直径（Nu数的有效因素），因此较高的传热系数并不一定意味着较高的Nu数字。该系统还观察到了其他令人难忘的图形、定量和定性结果，所有这些结果都在本文中进行了报道。
