Description

TECHNICAL FIELD

[0001] The present application relates to the field of autoclave, in particular to a kind of autoclave with heat conducting oil. BACKGROUND

[0002] Autoclave is a kind of pressure vessel, so its common structure is a cylinder with one end closed and the other end open, which provides necessary heat and pressure for the compaction and curing of advanced composite products. Usually, the size of aerospace composite parts is very large, so the autoclave must be larger. At the same time, some composite molding requires higher pressure and temperature, resulting in very large heat consumption when the autoclave is working.

[0003] One of the main advantages of autoclave is suitable for the production of a variety of materials, as long as the curing cycle, pressure and temperature of the composite material are within the limits of the autoclave. Another advantage of autoclave is its flexibility in pressing composite parts. Usually, the parts are laid on one side of the mold, then put into a vacuum bag, and the pressure on the parts is further strengthened by vacuumizing the bag. Therefore, autoclave molding technology can produce composite parts with different shapes. Autoclave is widely used in the production of aerospace advanced composite parts.

[0004] Autoclave can be divided into composite autoclave, vacuum autoclave, carbon fiber autoclave, high temperature and high pressure autoclave, aerospace autoclave, sports goods autoclave,

[0005] Automobile parts autoclave, experimental autoclave, etc.
