The article presents a comparative analysis of calculation results and measurement results of cooling module built on the basis of design calculations. The computations were made in software dedicated to the calculations of heat exchangers. The measurements were performed on a cooling system mounted in a special purpose vehicle together with a combustion engine, which was loaded by an engine dynamometer. Based on the comparison between input data for calculations and results of measurements, differences were found, therefore changes were proposed to be made in the model.

Combustion Flow

Engine is carried the test on the thermal balance test and the drag test in the vehicle working condition to analysis the distribution of energy from combustion. The heat of coolant that combustion flow into the cooling system in different temperature is not the same. The results show that the engine heat comes into the cooling system ranging minimum at 3000-4000r/min, the effective power output accounts for the total energy up to 25% at full load reaching the maximum. Based on the data, it is established the control system of engine cooling module that can be controlled by the engine speed, torque and power, when the ECU reads the signal to forecast the combustion energy flow to the cooling system in the target vehicle working conditions establish the cooling module heat release control system.

The automotive cooling system has unrealized potential to improve internal combustion engine performance through enhanced coolant temperature control and reduced parasitic losses. Advanced automotive thermal management systems use controllable actuators (e.g., smart thermostat valve, variable speed water pump, and electric radiator fan) that must work in harmony to control engine temperature. One important area of cooling system operation is warm-up, during which fluid flow is regulated between the bypass and radiator loops. A fundamental question arises regarding the usefulness of the common thermostat valve. In this paper, four different thermostat configurations were analyzed, with accompanying linear and nonlinear control algorithms, to investigate warm-up behaviors and thermostat valve operations. The configurations considered include factory, two-way valve, three-way valve, and no valve. Representative experimental testing was conducted on a steam-based thermal bench to examine the effectiveness of each valve configuration in the engine cooling system. The results clearly demonstrate that the three-way valve has the best performance as noted by the excellent warm-up time, temperature tracking, and cooling system power consumption.

Here numerical analysis is focused on optimizing the vehicle heat exchanger by varying the geometry in which it is integrated in the vehicle’s cooling system. This analysis also elucidates how one can affect the different parameters that influence heat exchanger performance in order to optimize their functioning, in relation to the geometry in which they are integrated. The two-dimensional computational code developed permits optimizing the performance of the cooling module by positioning different heat exchangers, in both driving and stop phases of the vehicle. The ultimate aim is to develop new approaches to controlling heat exchanger positions in a real vehicle cooling system.

This paper details the design of a Pitot tube used for water flow rate measurements in large pipes. The paper describes first the nowadays commonly used device (simplex pitot), based on standard CTI Code ATC-105 from Cooling Tower Institute [1]. The disadvantages of the simplex pitot are pointed out, and the detailed description of the proposed device (multiport pitot) is explained. The Multiport Pitot, which design is also based on norm ATC-105, is able to perform real-time measurements. The paper also includes the results obtained from the water flow rate measurements made in the cooling system of a thermal power plant in Mexico. These measurement results were compared to simulation results obtained with a computational commercial simulation tool.
