CREATION AND ANALYSIS OF A MODEL FOR CALCULATION OF HYDRAULIC LOSSES IN A HEAT EXCHANGER
Abstract
The performance and functioning of the traction battery (TAB) is the most important issue considered when designing an electrified vehicle. In a modern electric car, there are a number of systems that ensure the maintenance of the characteristics of the TAB. Namely, the key role is played by the temperature control system, which maintains a normal temperature regime. This system can be both air and liquid. The authors note that the liquid one is more efficient in terms of heat transfer and allows you to get the most stable temperature regime. In order to determine the optimal parameters of hydraulic resistance and mass flow, the approach of applying the finite element method of calculation is considered. The article considers a model for calculating the hydraulic resistance of a heat exchanger, which allows calculating the parameters of the TAB thermal control system. As a result of the analysis, the authors come to the conclusion that this model allows us to obtain the necessary data that allow us to judge the design of the elements of the thermal control system. It is also noted that for the most complete calculation, it is necessary to conduct a simulation of the thermal state of the batteries.
