A preheater based on energy-saving and high-efficiency heat exchange effects for aerospace tests

Abstract

The invention discloses a preheater based on energy-saving and high-efficiency heat exchange effects for aerospace tests, and relates to the technical field of aerospace tests. The structure composed of the four parts of the body has a shunt strengthening mechanism installed and connected inside it. Several heat exchange pipelines are fixedly installed inside the shunt strengthening mechanism. When inside the device, the diversion strengthening mechanism of the network structure can quickly divide the air fluid, and each grid of the network structure corresponds to some sections of the heat exchange pipeline, thereby improving the preheating of the air As a result, the preheating time of the air is shortened. In addition, the diversion strengthening mechanism can not only realize the rapid diversion of the air fluid, but also improve the self-strength of the entire preheater and improve the practical performance. The structure is scientific and reasonable, and it is safe and convenient to use.

Description

technical field [0001] The invention relates to the technical field of aerospace tests, in particular to a preheater based on energy-saving and high-efficiency heat exchange effects for aerospace tests. Background technique [0002] A comprehensive inspection test to verify the performance, life and reliability of the spacecraft. Spacecraft test inherits the procedure and technology of rocket test, and develops space environment test on this basis, which is generally divided into development test, identification test, acceptance test, life test and reliability test, etc. The test objects are parts, components, subsystems and spacecraft as a whole. The environmental stress screening test of components, the test of the recovery system, the test of the attitude control system, the thermal vacuum test of the temperature control system, the modal test of the structural system, etc., are the basis of the overall test of the spacecraft. The environmental test is the main content ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a preheater based on energy-saving and high-efficiency heat exchange effects for aerospace tests, which solves the problem that the existing air preheaters used in aerospace tests are not only complicated in structure, but also Moreover, the function is also relatively simple. When the air preheater is working normally, the air to be preheated enters from the air inlet of the preheater. Because the internal structure of the preheater lacks a shunt structure, the air fluid cannot be discharged quickly. After being preheated, the air preheating time is long and the effect is not ideal. In addition, due to the lack of pre-filter structure, the air fluid with dust entering the preheater will adhere to the air fluid of the preheater. The inner wall or the surface of the heat exchange tube needs to be cleaned regularly, which is time-consuming and labor-intensive.
