Calculated from the radiator performance test results, can be calculated from the engine parameters, so you can calculate the installation efficiency of each basic model. When an improved design or variant vehicle design is performed, the known tool can calculate the cooling constant. The installation efficiency is obtained from the test and is close to the actual situation. The ratio can be calculated directly from the cooling constant and compared with the test result. Thus, the cooling capacity of the cooling system can be quantitatively analyzed, which replaces the previous qualitative analysis that compares the radiator heat dissipation with the engine heat dissipation. For this purpose, a calculation program for cooling performance was compiled. Taking the example as an example, a method for calculating the cooling performance of L was described and compared with the test results.

Comparative examples of design and calculation of cooling systems and tests In the design of the rear passenger car, the above arrangement was adopted and in the calculation, since it has the same engine and similar engine system layout. Therefore, the installation efficiency can be calculated first according to the cooling performance test results, quoted in the calculation of the design, and the cooling constant can be calculated. The cooling performance test was carried out on a rotating drum test stand. The calculation results were compared with the cooling performance test results and the test results. : Rotational ambient temperature Cooling lj Constant l The calculated value of the test value Comparing the calculated result with the test result, it shows that the new cooling performance calculation method is close to the experimental value, which truly reflects the cooling performance, and can be used in future cooling system design. widely used.
