Abstract

The requirements for modern cars are becoming increasingly stringent, so advanced technologies are widely used in the automotive industry. Today’s realities force manufacturers, taking into account the environmental requirements for cars, the economic component and competitiveness, to conduct intensive research work in the field of improving the components and design of vehicles as a whole. Machine units are becoming increasingly loaded, which in turn increases their operating temperature. The problem of heat transfer is very acute when designing modern cars, the bulk of components and units currently require additional forced cooling. When developing a vehicle, conducting a thermal calculation of components, the main attention is paid to its purpose and conditions of further operation, especially for trucks and special vehicles. These issues are solved by installing additional cooling systems, the key component of which is a heat exchanger. The efficiency of heat exchangers depends on many factors: the material of manufacture, the principle of operation, the installation location and, first of all, the structural component. Due to the high specific surface area, porosity and strength, honeycomb regenerative heat exchangers are widely used in many industries, including the automotive industry. Research on increasing the efficiency of these heat exchangers is being conducted by scientists all over the world. One of the main parameters that increases the efficiency of the heat exchanger is the geometry of the regenerator elements, but it is necessary to take into account the pressure drops in the system, which change when the angle of inclination of the plates changes. Therefore, when applying these studies, when developing heat exchangers, it is necessary to take into account the necessary parameters that need to be achieved for a specific cooling system.

Keywords: vehicle, heat exchanger geometry, plate inclination angle, pressure drop, air flow rate.
