▎ 摘　　要

NOVELTY - The heating middleware has two side holes that are provided on the cylinder wall of the pressure heating middleware main portion. The inner wall of the pressure heating middleware main portion is provided with an electric heating structure, and the two ends of the pressure heating middleware are provided with connecting threads. The electric heating structure includes an aluminum cylinder (20), and the graphene film (21) is plated on the inner cylinder wall of the aluminum cylinder. The aluminum cylinder is embedded in the annular groove on the inner wall of the heating and pressurizing middleware. The spiral heating coil is embedded in the annular groove on the inner wall of the heating middle portion. USE - Pressure heating middleware. ADVANTAGE - The pressure heating middleware uses pressurized heating middleware to connect the upper end and the lower end of the pressure holding test chamber, which avoids drilling holes in the pressure holding test chamber, prevents damage to the pressure holding test chamber, and improves the accuracy of the experiment. The electric heating structure is installed in the pressurized heating middle portion, which improves the heating efficiency and shortens the experiment time. The electric heating structure is set on the pressurized heating middle piece, so there is no need to change the structure of the pressure holding test chamber. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a split-type fidelity corer intracavity temperature control structure; and (2) a temperature control method of the temperature control structure in the cavity of split type fidelity corer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the pressure heating middleware.
