The development of electronic device technology which currently has a minimalist size requires a new breakthrough to develop a cooling system to replace the fan and save electricity. Technology that is quite relevant to replace the cooling system is a technology that utilizes the vortex flow to accelerate the synthetic jet-based heat mixing process. In this study using an experimental method that installs a temperature gauge on the side of a flat plate heat source for 3600 seconds. The working principle of synthetic jet uses a membrane to produce a vortex flow through one nozzle. From the test results using the sine, square, and triangular wave excitation modes at a frequency of 40 Hz, 60 Hz, 80 Hz and 100 Hz. It can be concluded that the 80 Hz sine excitation wave mode provides the best cooling effect compared to the square wave and triangle excitation modes.
