In this paper, the improvement of heat exchange in a compact heat exchanger that is used in the automotive cooling system is numerically studied due to the importance that this part of the automotive represents in removing the heat generated in the automotive engine. The study adopted CFD simulation to introduce a new design of radiator that included changing the geometry and material of the tube while maintaining the same cross-section area In addition, the study also included replacing the shape of the fins from the louver to plain fin with the increase in the number of tubes. The study used a water-Ethylene glycol mixture (50:50) as a hot fluid with four flow rates (10, 12, 18, 24) l/h, (75, 85, 95) °C inlet temperature, and air as a cold fluid with 1.5, 2.5, 4.5, 5.5) m/s and (35) °C inlet temperature. Through the results obtained, the designed model appeared to have a higher thermal performance than the standard model due to the material and shape of the tube and fins. The designed model performed well, achieving an improvement ratio of (18.6%) for the heat transfer rate, (13.8%) for the overall heat transfer coefficient for the hot fluid, and (29.8%) for the air-side heat transfer coefficient

A four-pass cross-flow heat exchanger was developed and manufactured in this practical study for two types of tubes: smooth and triangular finned tubes. The length of the tube is 250 mm, for a smooth tube the inner and outer diameter (19, 21 mm), and (19, 21 and 24 mm) the inner, outer diameter and the fin root for the finned tube respectively. Water is used as a hot fluid inside the tubes and air is used as a cold fluid outside the tubes. Inlet hot fluid temperatures were 50, 60, 70, and 80 °C, with three air speeds (1, 2, and 3 m/s), and volumetric flow rate (2, 3, 4, and 5 l / min) held steady at 25 ° C. The finned tube outperformed the smooth tube in terms of heat transfer rate, heat transfer coefficient, total heat transfer coefficient, and effectiveness, according to the findings.
