“…An accurate valuation of probable air-side heat transfer surface geometries is a prerequisite for the best possible heat exchanger plan. A simplified and translucent analytical procedure for the evaluation of multi louvered fin and flat tube heat exchanger geometries that permit maximal performance for given borderline conditions has been developed [15]. Figure 10 shows a schematic diagram of the test apparatus used in the study.…”

The heat transfer enhancement is recycled in many engineering uses such as heat exchangers, refrigeration and air conditioning structures, chemical apparatuses, and automobile radiators. Hence many enhancing extended fin patterns are developed and used. In multi louvered fin, in this segment for multi-row fin and tube heat exchanger, an increase in heat transfer enhancement is found 58% for ReH = 350. When the Reynolds number is 1075, the temperature gradient is more distinct for greater louver angle that is the higher heat transfer enhanced for large louver angle. For variable louver angle heat exchanger, the maximum heat transfer improvement achieved by 118% Reynolds number at 1075. In the vortex generator for the delta winglet vortex generator, the extreme enhancement of heat transfer increased to 16% compared to the baseline geometry (at ReDh = 600). For a compact louvered heat exchanger, the results showed that a regular arrangement of louvered fins gives a 9.3% heat transfer improvement. In multi-region louver fins and flat tubes heat exchanger, the louver fin with 4 regions and the louver fin with 6 regions are far better than the conventional fin in overall performance. At the same time, the louver fin with 6 regions is also better than the louver fin with 4-region. The available work is in experimental form as well as numerical form performed by computational fluid dynamics.

“…Modern-day studies are carried out to develop current HE systems, for instance through parametric studies to evaluate different HE fins' layouts and establish best practices to characterise these devices [3]. This can be achieved through evaluating the performance of flat-tube heat exchangers with louvered fins and optimise them [4], or through describing the aerodynamic impact of the fins' shape on the HE performance [5]. Computational Fluid Dynamics (CFD) techniques are highly used for this type of research, for instance, to assess and improve the performance of a HE through conjugate heat transfer [6], to evaluate the performance of a HE using a multiphase working fluid, applying an advanced treatment of the phase interfaces within a complex-shaped domain [7] and to characterise a HE by studying only a portion of the device itself [8].…”

The fabrication of assembled radiator features high production efficiency and causes no pollution to the environment thanks to the application of mechanical processing. Nevertheless, the application range of assembled radiator is greatly limited due to the low thermal efficiency. In the environment-friendly modern society, researchers are racking their brains to answer the difficult question of how to improve the thermal efficiency of assembled radiator to the level of brazed radiator. Against this backdrop, this paper compares the heat dissipation performance of flat tube type and wasp-waisted tube type automobile radiators through simulation and experiment, and discovers that wasp-waisted tube type assembled radiator has higher heat transfer capacity. It is proved in this research that the heat dissipation performance of assembled radiator can be improved by optimizing the shape of radiating tube, especially minimizing equivalent diameter and expanding the circulation area in the tube. Suffice it to say that this research provides valuable references for future study on the heat dissipation performance of assembled radiator.
