A liquid cooling plate structure with multiple channels is proposed for linear synchronous motor in this paper. Firstly, a conjugate heat dissipation model is established, and coupling analysis with fluid and temperature fields is performed by finite volume method with different channel numbers and section shapes. The simulation results show that, the cooling capacity of proposed cooling plate is observably improved, especially for 6 channels cooling plate with elliptical section. Afterwards, adopting boundary optimization by quadratic approximation algorithm, the section dimensions of 6 channels plate with elliptical section are further optimized to realize a trade-off with heat transfer coefficient and pump power. The optimized scheme can improve heat transfer coefficient by 33.03% and reduce the pressure drop by 85.37% compared with original scheme.
