Abstract

The invention discloses a cooler. The cooler is composed of an incoming flow inlet (1), a shell (2), an expansion segment (3), a flow guide cone (4), a light pipe cooling segment (5), a cooling lightpipe (6), a cooling light pipe cooling water inlet (7), a cooling light pipe cooling water outlet (8), a fin pipe cooling segment (9), a cooling fin pipe (10), a cooling fin pipe cooling water inlet (11), a cooling fin pipe cooling water outlet (12), a flow guide cone cooling water outlet (13), a shell cooling water outlet (14), an incoming flow outlet (15), a flow guide cone cooling water inlet (16), and a shell cooling water inlet (17). The cooler is used for cooling high-temperature incoming flow gas.

Description

technical field [0001] The invention relates to a cooler, in particular to a cooler with low flow resistance of high-speed airflow, which is suitable for occasions where the incoming flow is high-temperature, high-speed airflow and low flow resistance of cooling equipment is required, such as rocket engines, ramjet engines, and aeroengines. Test system and ablation test system, etc. Background technique [0002] Some rocket engines, ramjet engines, aeroengine test systems and ablation test systems need to be equipped with coolers, whose function is to cool the high-temperature, high-speed airflow for subsequent processing. For example, on the high-altitude simulation test bench for active ejection rocket engines, the temperature of the engine gas can reach above 2800K. Generally, a cooler is installed between the diffuser and the ejector to reduce the temperature of the engine gas to below 373K to protect downstream equipment. The gas specific volume of the engine can be re...
