Problems solved by technology

However, for aircraft that can hover in the air (such as helicopters, etc.), when the hovering or flying speed is slow, the air convection is weak at this time, the air-cooled heat dissipation efficiency is rapidly reduced, and the heat of the engine cylinder cannot be dissipated in time. Normal use is very affected

Abstract

The invention provides a novel engine cylinder cooling structure. The structure comprises an air cylinder body, an air cooling mechanism and a water cooling mechanism, wherein the air cylinder body isprovided with a first heat dissipation section used for being connected with the air cooling mechanism and a second heat dissipation section used for being connected with the water cooling mechanism,the air cooling mechanism is connected with the first heat dissipation section of the air cylinder body, and the water cooling mechanism is connected with the second heat dissipation section of the air cylinder body. Heat dissipation of an engine cylinder is divided into two parts of air cooling heat dissipation and water cooling heat dissipation, when air flows through an aircraft, air convection is strong, heat dissipation is mainly conducted through the air cooling mechanism (the water cooling mechanism can also conduct heat dissipation), although compared with the prior art that arrangedcooling mechanisms are all air cooling mechanisms, a heat dissipation effect in a state is poor, heat dissipation of the engine cylinder can be met, and when no air flow comes, the water cooling mechanism is mainly used for heat dissipation, so that at least the most basic heat dissipation requirement can be guaranteed, and normal and lasting operation of components is guaranteed.

Description

technical field [0001] The invention relates to the field of aerospace and aviation, in particular to a novel engine cylinder cooling structure suitable for hovering aircraft. Background technique [0002] In the aerospace field, the engine cylinder in an aircraft (such as an aircraft with fixed wings, a helicopter or a rotorcraft) is a core component. The engine cylinder is prone to heat during operation, and it needs to be dissipated in time. In the prior art, during the flight of the aircraft, the air flow is large, and the heat dissipation by convection (that is, air-cooled heat dissipation) is effective, and the structure and layout are simple. However, for aircraft that can hover in the air (such as helicopters, etc.), when the hovering or flying speed is slow, the air convection is weak at this time, the air-cooled heat dissipation efficiency is rapidly reduced, and the heat of the engine cylinder cannot be dissipated in time. Normal use is very affected. Contents ...
