Abstract To optimize printed circuit heat exchangers, the experimental heat transfer characteristics of two-phase flow boiling in zigzag channels of PCHE were investigated. The experimental conditions cover mass fluxes of 100~400 kg /(m²•s), vapor qualities of 0.1~1.0, heat fluxes of 1.5~12.5 kW/m², and saturation pressures of 0.15~0.35 MPa. The research results show that, the heat transfer coefficient initially increases and then decreases as the vapor quality increases, representing a maximum at vapor quality of 0.85~0.9; as the heat flux increases, the heat transfer coefficient increases at a vapor quality
