Abstract

The invention is a steady state Tokamak diverter cooling heat sink, including heat sink plate. Its characteristic is there are a number of cooling channels in the heat sink plate. In the lateral of the heat sink plate, the adjacent cooling channels are connected by pipes to form a series circuit. For the steady long - pulsed operated Tokamak device, the energy deposition on the diverter will be great. So the diverter must have a strong initiative cooling system. The invention can meet those requirements.

Description

technical field

[0001] The invention belongs to a cooling device in a magnetic confinement nuclear fusion device, in particular to a steady-state tokamak divertor cooling device. Background technique

[0002] In the magnetic confinement nuclear fusion device, the energy for heating the plasma and the energy generated by fusion will be mainly deposited on the divertor, and the power density generated by these energies on the divertor will reach 20MW / m 2 above. Such a large power density, if there is no effective energy transmission speed to remove the energy as fast as possible, will quickly cause the temperature on the divertor to rise to a height that the material cannot withstand. Most of the divertor tokamaks operated in the past and currently are discharges with plasma pulse lengths ranging from a few seconds to more than ten seconds. Although the power density on the divertor is high, the total energy is not large. The temperature rise caused by the filter will not be...
