“…The CHF values were > 50 % higher than for smooth tubes when the Hypervapotron was used in various experiments. It can easily withstand 20 MW/m 2 , as has been verified by several experiments [33,34]. It used in the dome liner and also in some places in first wall at ITER to deal with heat fluxes ∼ 5 MW/m 2 .…”

“…It used in the dome liner and also in some places in first wall at ITER to deal with heat fluxes ∼ 5 MW/m 2 . For an equivalent flow, the Hypervapotron has the highest CHF limit, and the pressure drop is also lower than for swirl tubes [27,34].…”

“…Milnes [9] et al used computational fluid dynamics (CFD) software to predict the heat transfer coefficient(HTC) variation of the hypervapotron structure and found that the numerical simulation method was more accurate calculate the local heat transfer coefficient of hypervapotron structures. Wang [10] et al analyzed the maximum temperatures of different hypervapotron structures and compared their heat transfer efficiencies. In summary, the hypervapotron structure can significantly improve the heat transfer between the plasma facing component(PFC) and the coolant, with the best heat transfer performance of the triangular fins.…”

High flux components in fusion reactor are designed to transfer high thermal loads from the core plasma under steady-state operation and emergency conditions. In order to improve the heat transfer ability, hypervapotron structure is proposed to promote the heat transfer performance by optimizing the thermal hydraulic design. In this paper, three-dimensional numerical simulation was carried out using CFD methods for the improved solution of the first wall. The results show that the heat transfer performance of the triangular fin structure with tilt angle of 30° is superior to 0 °, 15°and 45°. At a typical flow rate of 2 m/s, the heat transfer efficiency of the triangular fin with tilt angle of 30° improved by a maximum of 118.1% compared with that of the smooth flow channel. In addition, the heat transfer performance of the triangular fin structure is better than other fin structure, and its maximum temperature drops by 136.3K compared to the smooth flow channel. The design solution may provide a viable new method for efficient cooling of future fusion reactor components with high heat flux.

“…To mitigate these difficulties, a key technology is target cooling under a high heat load to keep the Li layer as solid. A number of highly efficient cooling technologies under a high heat load have been developed in nuclear fusion systems or gas turbines, and many research papers and state-of-the-art-reviews have been published [7][8][9][10][11][12][13]. A high heat load of up to 20-30 MW/m 2 is incident on the inner wall of the magnetic confinement fusion reactor due to the plasma concentration.…”

“…A high heat load of up to 20-30 MW/m 2 is incident on the inner wall of the magnetic confinement fusion reactor due to the plasma concentration. Several technologies have been developed to remove these high heat loads, and one of the most promising devices is HyperVapotron [7,8]. A typical HyperVapotron has fins attached to a rectangular channel, which causes turbulence and efficiently removes heat.…”

Accelerator-driven neutron sources have been developed worldwide for boron neutron capture therapy (BNCT) instead of nuclear reactors. Nagoya University is currently developing a compact DC accelerator driven BNCT system using a sealed lithium (Li) target. The target receives a high heat load by a proton beam, and the heat then requires efficient removal. This study developed a high-efficiency heat removal technique that uses V-shaped staggered ribs on the heat removal side of the flow channels. We performed experiments using an electron beam to confirm the technique performance. The results showed double the heat removal performance compared to the smooth surface channel. The value expected to sufficiently remove 6.6 MW/m2 of heat load provided by the proton beam at the Nagoya University neutron source for BNCT.
