Perancangan dan Pengujian Radiator Tester Skala Laboratorium yang Terintegrasi Pengatur Putaran Mesin dan Hembusan Angin (Regulator Wind Blower)
Abstract: Cooling system in
the engine functions as the protector of the machine by absorbing the heat.
Heat engine is produced by fuel in the cylinder. The heat is deliberately
created to generate energy, but it will cause excessive heat if it is left
unchecked (over heating effect). In order to prevent overheating and keep the
machine temperature, then it uses radiator. How effective radiator is used can
be seen by using a tool called a radiator tester. Therefore, this research was
Designed a Trial Radiator (Radiator Tester) Laboratory Scale Which is Completed
by Round Handler’s Machine and Regulator Wind Blower on Diesel Engine L 300.
This research was done by testing the car L 300 diesel in the field then
noted rpm and air speed that blew into the radiator. The process of designing a
radiator tester L300 diesel engine laboratory scale were making the framework
platform machine, making radiator tester cooling system machine to set up a
thermometer in the radiator hose in and out, making a mechanism round handlers
machine, making a regulatory mechanism wind blower and installing a trial
radiator with round handlers machine and wind blower. The rpm test result and
air speed on the field was applied to the radiator tester laboratory scale.
From the results of the tests, it showed that there was an increase in
value of the effectiveness of the radiator without external airflow to engine
speed 1000 rpm and the average value was 0.483. Whereas, there was a decrease
on the effectiveness of the radiator when given outside air flow 2.3 m / s at
1500 rpm engine speed, which was 0.63.
