Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment, but should not be interpreted as that the scope of the subject matter of the present invention is only limited to following embodiment, under the situation of not departing from above-mentioned technical thought of the present invention, all according to this field Various modifications, substitutions and alterations made by ordinary technical knowledge and common means are included in the scope of the present invention.

[0033] The split multi-stream heat exchanger in this embodiment includes a heat exchange core and a core connecting pipeline 5 . The heat exchange cores are divided into the hot end heat exchange core 8 (heating core), the middle temperature end heat exchange core 11 (heating / cooling core) and the cold end heat exchange core 1 (cooling core). The heat exchanging core is composed of fluid passages and cold plates, medium temperature p...

Abstract

The invention discloses a separated type three-flow heat exchanger which comprises a hot-end heat exchange core body, a medium-temperature-end heat exchange core body, a cold-end heat exchange core body, a core body connecting pipeline and a heat transfer working medium. The hot-end heat exchange core body, the medium-temperature-end heat exchange core body and the cold-end heat exchange core bodyare arranged in a spacing way in a space; fluid courses in the hot-end heat exchange core body, the medium-temperature-end heat exchange core body and the cold-end heat exchange core body and the core body connecting pipeline form a sealed splitless loop with a single path; and the heat transfer working medium is filled in the loop. The separated type three-flow heat exchanger provided by the invention has the performances such as good heat exchange effect, compact structure, light mass and the like, heat can be transmitted over long distances at the same time, and higher and further heat transfer can be realized compared with a heat exchanger with a common heat pipe.

Description

technical field [0001] The invention relates to the technical field of separated heat exchangers, in particular to a separated three-stream heat exchanger used in aircraft, which can transmit heat over long distances without power. Background technique [0002] A large amount of heat is generated in the aircraft environmental control liquid cooling system and the integrated electromechanical thermal management system of the fighter. This heat has to be transferred out somehow. The heat exchanger used on the aircraft needs to have good heat exchange effect, compact structure, and light weight. In the process of heat transfer, the total system needs a large number of pumps, liquid storage tanks, control valves and other equipment, and the weight and space of the system are heavily occupied. , affecting system reliability. Contents of the invention [0003] The present invention aims to provide a separate three-stream heat exchanger, which can be used for long-distance unpo...
