INSTRUMENTAL CONTROL AND DIAGNOSIS OF THE TECHNICAL CONDITION OF HEAT EXCHANGERS OF VEHICLES
The urgency of the investigated problem is caused by low informational content and the reliability level of measurement results of control means and methods, monitoring and diagnosing the heat transfer surfaces of heat exchangers in vehicles.The article is aimed at analyzing the imperfection of existing methods and means of evaluating of the heat exchangers performance, as well as at identifying more efficient technical systems and devices that, along with their primary functions, perform measurement functions.The main theoretical methods for investigating this problem were analysis and synthesis, the dialectical interconnection of which allowed us to identify possible ways to improve the method of instrumental monitoring and diagnosing heat exchangers in vehicles in operation. At the stage of experimental studies, physical modeling and statistical methods were used to obtain the regularities of the change in the technical condition of the heat exchangers from the operating time.The main result of the work is the implementation of new technical solutions in the design and software for creating a specialized stand that will allow monitoring and diagnosing the technical condition of heat exchangers with the ability to quantify the main operating characteristics. The use of the stand's capabilities, in its turn, will allow to predict the residual resource of heat exchangers, as well as to determine the scope and content of works to restore their efficiency.The materials of the article can be useful for service centers and enterprises specializing in maintenance and repair of heat exchange equipment.
