Abstract

The invention relates to a water cooling module for a Tokamak device adopting a stainless steel copper alloy composite plate and a processing method of the water cooling module. The water cooling module comprises a water cooling unit, a water inlet unit and a water outlet unit. The water cooling unit comprises a plurality of water cooling pieces, each water cooling piece comprises a water cooling heat sink, a first oxygen-free copper layer and a first carbon base layer, and a first direct cooling flow channel is formed in each water cooling heat sink. The water inlet unit and the water outlet unit each comprise a water inlet and outlet heat sink, a second oxygen-free copper layer and a second carbon-based layer. The water inlet and outlet heat sink is provided with a second direct cooling flow channel. The water-cooling heat sink and the water inlet and outlet heat sink are made of stainless steel / copper alloy composite plates through machining. The connecting unit comprises a connecting heat sink, a third oxygen-free copper layer and a third carbon-based layer. According to the invention, the heat removal capability is excellent, the internal flow channel is continuous and smooth, and the flow resistance is less; the modular design is adopted, the high-field-side first walls of different sizes and specifications can be formed by a plurality of water cooling modules, different design requirements are met, and meanwhile maintenance and quick replacement of damaged parts are facilitated.

Description

technical field [0001] The invention relates to the technical field of magnetic confinement nuclear fusion devices, in particular to a water-cooled module of a tokamak device using a stainless steel-copper alloy composite plate and a processing method thereof. Background technique [0002] The tokamak device is a circular magnetic confinement system, relying on the circular magnetic field coil and the axial plasma current to generate the circular magnetic field and the poloidal magnetic field respectively, and the two are superimposed together to form a closed, helical magnetic field to confine particles in it. The confined plasma is heated to a high temperature of hundreds of millions of degrees by means of induction, neutral beam, ion cyclotron resonance, electron cyclotron resonance, and low clutter to achieve fusion reaction. [0003] The high-field side is located on the inner wall of the central column of the vacuum chamber of the tokamak device, and is the part with ...

AI Technical Summary

Problems solved by technology

Due to the mechanical connection between the graphite tile and the heat sink, the contact thermal resistance is large, so the heat deposited on the graphite surface cannot be discharged in time; in addition, the heat dissipation area of ​​the cylindrical flow channel is small and the heat dissipation capacity is poor. Therefore, the existing The high-field first wall design cannot meet its application requirements under high thermal load conditions
