The invention discloses an integrated heat radiating device of a super-gravity acceleration high-speed geotechnical centrifuge. A cylindrical centrifugal bin wall is internally coated with a rotor ofthe high-speed centrifuge; the outer side of the centrifugal bin wall is a cylindrical cold water jacket; helical flow guide blades are installed between the cylindrical centrifugal bin wall and the cylindrical cold water jacket; a composite upper cover and a composite lower cover of the cylindrical centrifugal bin wall are hermetically connected with the centrifugal bin wall; the composite uppercover is provided with a cold air outlet pipe and a vacuum sucking pipe; the center of the composite lower cover is provided with a centrifuge supporting and mounting hole; and the composite lower cover is provided with a cold air inlet pipe, a high-pressure water supply pipe and a high-pressure air supply pipe. By virtue of integrated cooling of a plurality of cooling methods such as direct coldair cooling inside a centrifugal bin, cold water cooling of the sidewall of the centrifugal bin, vacuumizing and high-pressure water and vapor mixed spraying, the integrated heat radiating device disclosed by the invention guarantees that the heat of the super-gravity acceleration high-speed geotechnical centrifuge can be cooled in time, so the operation temperature of the centrifugal bin is controlled within a certain range, and the use functions of instruments are not affected.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to an integrated heat dissipation device of a supergravity acceleration high-speed geotechnical centrifuge. Background technique [0002] High-acceleration, high-speed geotechnical centrifuge is an indispensable device for the reproduction test of geological evolution processes such as rock-soil evolution, geological structure evolution, and geological disaster restoration. With the continuous increase of the acceleration g, the heat dissipation problem of the geotechnical centrifuge itself becomes a difficult problem, because the higher the speed and line speed of the centrifuge, the greater the heat generated by the friction between the rotating arm, the hanging basket and the air. When the acceleration is below 500g, it can generally be cooled by a cooling fan unit or natural wind circulation. However, when the acceleration increases to more than 1000g, or even more than 1500g, the h...
