Abstract

The invention discloses a novel air-fuel annular heat exchanger for an aero-engine, comprising a heat exchanger core body, a test pipe joint, and an outer cylinder, and the heat exchanger core body includes a front end plate, a rear end plate, and several heat exchange tubes , test tubes, several positioning rods, several baffles I, several baffles II, an inner cylinder, and an annular cavity. In other cases, the demand for high-vibration levels is problematic.

Description

technical field [0001] The invention belongs to the technical field of heat exchanger structure design, and relates to an air-fuel annular heat exchanger suitable for ultra-high temperature and high pressure working conditions, high integration requirements, and high vibration level requirements. Background technique [0002] With the development of the field of aero-engines, the performance requirements of aero-engine heat exchangers are getting higher and higher, mainly manifested in: high integration requirements; new thermal cycle requirements, that is, ultra-high temperature and high pressure conditions; high vibration level needs. At present, the traditional engine supporting heat exchanger can no longer meet the requirements of new engines. Therefore, the present invention proposes an annular heat exchanger with a novel structure, which can meet the requirements of new engines. Contents of the invention [0003] The purpose of the present invention is to provide a...
