Heat Sink

LCP serves as a highly effective heat sink for power modules like IGBT,GTO and CPU, compare to air cooling heat sink it improve the installation density, reliability and reduce the energy consuption of the heat dissipation in the same time Through finite element thermal analysis method, it make the liquid cooling heat sink faster, more accurcy and reduce the test number, which guarantee the companent reliability in their rate condition and lifecycle
