Based on the numerical results, the second-order response surface models with high prediction accuracy for the wall average Nusselt number, friction coefficient and comprehensive thermal coefficient of X-type truss channel were built. The influence laws of truss rod diameter ratio, truss rod included angle and truss rod inclination angle on the cooling performance of X-type truss array channel were analyzed, and the optimal parameters were obtained by optimization. The results showed that increasing truss rod diameter ratio and truss rod’s included angle both can greatly improve average Nusselt number, but also increased the friction coefficient accordingly. Enlarging truss rod’s inclination angle first increased and then decreased the average Nusselt number and friction coefficient. Increasing truss rod diameter ratio, truss rod’s included angle and truss rod’s inclination angle made the comprehensive thermal coefficient first increase and then decrease. When truss rod diameter ratio was 0.0750, truss rod’s included angle was 60° and truss rod’s inclination angle was 33.79°, the heat transfer performance of the channel reached the best. When truss rod diameter ratio was 0.067, truss rod’s included angle was 37.88° and truss rod’s inclination angle was 31.36°, the comprehensive thermal performance of the channel was the best.
