英文摘要	High heat removal efficiency is an important requirement for the W/Cu divertor monoblocks in the design of future fusion reactors. In this study the stationary surface temperature distribution and the effects of armour thickness and coolant flow velocity on the thermal behavior of W/Cu monoblocks under high heat flux (HHF) loading has been investigated with steady finite element analysis. During HHF loading, a swath of low-temperature area with two extended parts was observed on the model surface, which is mainly related to the Gaussian distribution of heat fluxes and the heat dissipation from ending tubes. The stationary surface temperature showed a linear increasing function of armour thickness and a power decreasing function of flow velocity. It is thus concluded that the way to reduce the surface temperature of a monoblock by raising coolant flow velocity has an upper limit while the way by reducing armour thickness is effective continuously, especially under a higher heat flux.
