Problems solved by technology

The existing design methods for oil transmission of air-oil radiators are mostly designed for single oil heat dissipation cavity, and there is no redundant design. Therefore, there are 1) the shape and size take up a lot of space, but the cooling medium is not fully utilized, and the heat dissipation Poor efficiency; 2) There may be residues in the lubricating oil when the engine is working, or the oil inlet of the aircraft lubricating oil cooling cavity may freeze in a low-temperature environment. These phenomena often cause the radiator to fail to work normally

Embodiment Construction

[0027]The technical solutions of the present invention will be described in conjunction with the drawings of the present invention, and all other embodiments obtained in the art without making creative labor premises.

[0028]Such asfigure 1 A oil heat dissipation system is composed of a radiator body, a thermally controlled shutter, a pressure shutter, and a single-way shutter, and a heating tube, which is connected to each other as an engine and a tank tank.

[0029]Such asfigure 2As shown, the heat dissipation body is composed of an upper, lower cover, a separator, and a serrated fin. The heat sink is cooled by the engine oil in the outer stamping air to cool the engine, ensuring that the engine oil temperature is within the normal operating range. Temperature control shutters control the heat-radiator body needs to be in operation mode by perceive the oil-flowing stream temperature; pressure-active door perception of commonly used oil cavity oil port pressure changes, controlling the ...

Abstract

The invention belongs to the technical field of lubricating oil cooling, and discloses a lubricating oil cooling system. A lubricating oil runner is divided into two by a rib between an upper cover board and a lower cover board, a cooler is then divided into six lubricating oil cooling cavities by two partition boards, and a whole cooling main body is formed jointly at last, and is used as an aircraft ventral fin structure at the same time, so that an occupied space and the weight of the cooler are reduced at same cooling power; serrated fins are arranged in the six lubricating oil cooling cavities to form a common lubricating oil cavity of four flow paths of the lubricating oil runner and a backup lubricating oil cavity of two flow paths of the lubricating oil runner respectively, and by means of the dual-redundancy design, the product work reliability is greatly improved; and by designing the lubricating oil cooling cavities, with the multiple flow paths, and the S-shaped lubricating oil runner, not only is the structure weight reduced, but also air outside an aircraft is fully used as a cooling medium at the same time, so that the cooling power of the cooler is increased.

Description

Technical field[0001]The present invention belongs to the field of oil cooling heat dissipation techniques, and in particular, the present invention relates to a water heat dissipation system.Background technique[0002]Air-oil radiator on the aircraft, which utilizes air to heat-exchanger as a cooling medium to cool the heat skid in the oil supply system to reduce the oil temperature to meet the recyclable requirements. Existing air-oil radiator's oil transmission design method, mostly designed for single-slip oil cooling chamber, and there is no more design, and therefore there is 1) The size of the outer structure is large, but does not make full use of cooling media, heat dissipation Poor efficiency; 2) The oil can have a residue during operation, or the aircraft has a freezing phenomenon in a low-temperature environment, and these phenomena often lead to the cooling of the radiator.Inventive content[0003]The present invention proposes a multi-process oil-dissipating chamber and a...
