FUEL COOLING DEVICE Russian patent published in 2009 - IPC F25D3/12 

FIELD: heating systems.

SUBSTANCE: invention refers to obtaining cooled fuel for test benches of aircraft engines and their assemblies, and can be used in refrigerating equipment in various industries. Device includes fuel capacity 1 located inside it, cover 2, coil 6, heat insulation 19, and fuel supply 22 and discharge 23 pipelines. Device has vertical design and, in addition, includes protective casing 16, casing 16 cover 17, access door 20, perforated screen 7, temperature sensor 30, pressure sensor 29, fuel level pressure 27, pipeline 21 supplying fuel to main capacity 4. Main 4 and additional 1 capacities, their cover 2, protective casing 16, cover 17 of casing 16 and perforated screen 7 are mutually coaxial. Coil 6 is located inside additional capacity 1 and is made in the form of two spirals arranged one in the other in annular space between perforated screen 7 and walls of additional capacity 1. Spirals have gaps relative to walls of additional capacity 1 and walls of perforated screen 7. Inlet end of coil 6 is connected to pipeline 22 supplying fuel to main capacity 4.

EFFECT: improving reliability and manufacturability of the design, providing high dynamic capacity at optimum hydraulic resistance of its main lines, providing the possibility of obtaining cooled fuel with specified temperature, pressure and flow rate.
