“…Metal temperatures around the combustion chamber can exceed 1000°F. In order to prevent the overheating of the engine oil, cylinder walls, pistons, valves [16] , and other components by these extreme temperatures, it is necessary to effectively dispose of the heat [11][12][13] . It has been proved that a ordinary averaged sized car can produce enough heat to manage a house of five room comfortably warm during zero degree on cold weather.…”

Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are designed to service in four wheeler and heavy duty vehicles. The radiator is always a origin of heat to its environment, although this may be for either the function for cooling the fluid or of heating this environment, or coolant supplied to it, as for engine cooling. In existing plain fins type radiator are commonly used, which are usually set up in a cross flow arrangement made up of aluminum and copper alloy. Powerful fan and water pump is accompanied in this to greatly improve heat dissipation rate. The addition of fins is one of the way to improve and increase the rate of radiator cooling. This method follow the principle of increasing contact surface. Contact surface can also be increased by varying fin geometrical structure. In this project simple modification has been carried out in the existing fin geometry with a view to improve its heat dissipated rate. Also comparison of conventional coolant withNanofluids has been carried out by using PTC Creo 3.0 and analysis is carried out by using Ansys v16. The result are compared and optimum fin design is concluded.

“…Radiators are used for transferring heat or thermal energy for cooling in case of automobile engine and heating in case of refrigerators and air conditions. In past few years, several configurations have been developed for heat exchangers or radiators to maximize the heat transfer rates and utilize the available space effectively [1]. Spiral heat exchangers are compact and have better heat transfer efficiency.…”

“…They are spirally wound in a circular pattern through which the hot or cold fluid flows. Because of spiral shape, it has self-cleaning ability and even the problem of thermal expansion is in control [1]. The spiral profile helps in effective use of airflow area over it and the boundary layer formed over it is consistent.…”

Heat exchangers have its major application in automobile, air condition, refrigerator, power plants, and many others. Heat transfer characteristics and performance of Copper spiral heat exchanger are investigated and compared with pure water. Nanofluid can enhance thermos-physical properties. Experiment is carried out for water based SiO 2 Nanofluid with 15 nm average sized nanoparticle at varying air velocity and mass flow rate of fluid to investigate its effect on heat transfer coefficient. From the experimental data, a closed form solution for Nusselt number has been calculated using ∈-NTU method. A new correlation has been proposed as a function of Reynolds number and Prandtl number. The heat transfer rate, effectiveness, has been significantly higher compared to pure water and with increasing volume fraction of nanoparticles.

“…Lu et al [1][2] also adopted the porous medium model to simulate the pressure loss through the horizontal radiator in a small dry cooling tower. [3][4] analyzed the performance of a spiral tube heat exchanger, in comparison with shell and tube heat exchanger. Their optimized spiral design revealed that, heat transfer is enhanced compared to the shell and tube heat exchanger.…”

Abstract-This work consists to evaluate the impact of the tube design on the car radiator heat rejection performance. For this work we come up with two propositions, the first one consists to change the traditional tube shape "1.6x16 B-type" to "1.6x16 Dot B-type". The second one is just to change the traditional tube dimension from 1.6x16 to 1.4x16. After the two samples radiators were made, we will proceed to their performance analysis such as the heat rejection, the coolant pressure drops, and the airside pressure drop. For these performance tests we will use the company laboratory Multi-functional test bench (T-HWS-2H), and some mathematical formula to calculate our samples performance. At last we will compare our analysis results with the radiator "1.6x16 B-type" heat rejection data (Req.), which structural model and data is our research basic standard. The results show that the tube design has great impact on the radiator heat rejection performance. This work has been performed at HUBEI RADIATECH COOLING SYSTEM CO., LDT (HBR).
