- The Research aimed at analysis the test on the heat exchanger of types STHE and UTHE for cooling necessity on the Nanchang Diesl Motor of 2105 A-3 engine in order to obtain the characteristic and temperature of the cooling Water in Line with necessity of the motor. The testing was conducted on every heat exchanger i.e the parallel direction flow and the opposite direction flow. by using the heat transfer formula, it would be obtained the temperature change of the motor cooling water (Th) and analysis concerning the effectiveness on both was calculated based on the temparture difference at one end of tool deducted by the comparison logarithm of both temperature differences. Observation sampling used Slovin's Method. The analysis results obtained are for the tool with the STHE type, the temperature of the motor cooling water comes out from the heat exchanger , The parallel direction and the opposite direction are each 64 degrees celcius and 62 degrees celcius, the effectiveness levels are 29 percent and 40 percent, and the average temperature differences are 38 degrees celcius and 35 degrees celcius. for the UTHE type the parallel direction and the opposite direction each 60 degrees and 58 degrees celcius, the effectiveness is 40 percent and 58 percent, and temperature diffrences is 32 degrees and 24 degrees celcius.
