Embodiment Construction

[0017] figure 1 It is a structural schematic diagram of the present invention, a helicopter oil-water heat exchange device, including a heat exchanger 1 connected to the coolant pipeline and the oil pipeline of the engine for mutual heat exchange between the coolant and the engine oil, and also includes a heat exchanger 1 arranged on the coolant The outlet end or inlet end of the pipeline is used for cooling liquid radiator 2 for heat dissipation of the cooling liquid. Here, the outlet of the coolant pipeline refers to the end where the coolant flows out of the engine, and the inlet of the coolant pipeline refers to the end where the coolant enters the engine after cooling cycle. In this embodiment, the coolant and the engine oil in the coolant pipeline and the engine oil pipeline flow out through the engine respectively, and realize mutual heat exchange through the heat exchanger 1, and the engine oil flows back to the engine oil pot 17 and then flows to the engine for lubric...

Abstract

The invention discloses a helicopter oil-water heat exchange device and a helicopter. The helicopter oil-water heat exchange device comprises a heat exchanger connected with an engine coolant pipelineand an engine oil pipeline to be used for exchanging heat between coolant and engine oil; and the helicopter oil-water heat exchange device further comprises a coolant radiator for coolant radiating.The device fully utilizes the heat radiating capability of an existing cooling radiator, an engine oil radiator is omitted, obstruction of the engine oil radiator on a water tank radiating air passage is avoided, and the water tank radiating effect is high. Structural arrangement is optimized, the structure is compact, and the overall weight of a heat dissipation system is smaller compared with aconventional oil and water respective radiating manner. The oil-water heat exchange device has the better control ability on the engine oil temperature, and the problem about engine carbon depositioncaused by cylinder head temperature fluctuation is effectively avoided. An overflow pot is arranged on the coolant radiator so that the state of the coolant can be conveniently observed.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an oil-water heat exchange device used on an unmanned helicopter and the helicopter. Background technique [0002] An unmanned helicopter refers to a vertical take-off and landing (VTOL) unmanned aircraft that is controlled by radio ground remote control or / and autonomously. In the past ten years, with the research progress of composite materials, power systems, sensors, especially flight control and other technologies, unmanned helicopters have developed rapidly and are increasingly becoming the focus of attention. Unmanned helicopters sometimes fly for a long time, which also involves engine cooling. Traditional unmanned helicopters have poor heat dissipation capabilities. Contents of the invention [0003] In view of this, the object of the present invention is to provide a helicopter oil-water heat exchange device and a helicopter, which improve the heat dissipation...
