Heat dissipation system for power module

The present invention relates to a heat dissipation system for a power module. The heat dissipation system includes a first and a second heat dissipation plate forming a coolant flow path and separated from each other; and a first and a second inlet path sending the coolant supplied with different flow velocity and flux and extended to the coolant flow path of the first and the second heat dissipation plate; a first and a second inlet hole respectively connected to the first and the second flow path and supplying the coolant.
