Embodiment Construction

[0007] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0008] as attached figure 1 As shown, the air distribution device of the present invention includes a housing [1], a connecting rod [2], a large rocker arm [3], a small rocker arm I [4], a small rocker arm II [5], a rotating shaft [6], Bolt [7], valve piece I[8], valve piece II[9] and valve piece III[10], when the air distribution device is specifically manufactured and installed, all required components are designed and prepared according to technical and process requirements. Manufacture and installation must follow the following process and installation requirements: When the shell [1] is cast, the direction of the exhaust pipe of the shell [1] and the hot air pipe are 90°±30', and the direction of the cold air pipe and the hot air pipe is 90°±30'. 90°±30', shell [1] casting draft angle 1°~1.5°, the shell should be airtight test, ...

Abstract

An air mixing and distributing device with a temperature adjustment function comprises a shell, a connection rod, a large rocker arm, a small rocker arm I, a small rocker arm II, rotary shafts, a bolt, a valve piece I, a valve piece II and a valve piece III, wherein the connection rod, the large rocker arm, the small rocker arm I, the small rocker arm II and the rotary shafts on the shell form a parallel rocking shaft connection rod mechanism. When the large rocker arm is shaken, the valve pieces can be controlled to rotate around the rotary shafts in respective pipelines in a linkage mode through the parallel rocking shaft connection rod mechanism. When the included angle alpha of the valve piece I of an air exhaust path and the axis of the pipeline of the air exhaust path and the included angle alpha of the valve piece III of a cold air path and the axis of the pipeline of the cold air path are larger than 10 degrees and smaller than 80 degrees, at the time, the included angle beta of the valve piece II of a hot air path and the axis of the pipeline of the hot air path is equal to 90 degrees minus alpha, cold air and hot air are in a mixed state, and the mixing ratio of the cold air and the hot air can be controlled by controlling the included angle alpha. According to the device, the ventilation capacity of a ventilation system of a plane is improved, the temperature adjustment range is widened, circulation of fresh air in a cabin is improved and environment comfort of the cabin is improved.

Description

technical field [0001] The invention relates to the design field of an aircraft environment control system, in particular to an air mixing and distributing device with a temperature regulating function. Background technique [0002] In existing aircraft powered by piston engines, the environmental control system usually uses engine exhaust heating to achieve cabin heating, and uses a butterfly valve to adjust the flow of hot air to achieve temperature regulation. In this scheme, after the valve is closed or closed, little or no fresh air is supplied to the cockpit by the environmental control system, and the circulation of fresh air around the pilot is small, making the environment in such a small space of the cockpit particularly harsh. Contents of the invention [0003] In order to solve the problem of weak ventilation and poor temperature regulation effect of the aircraft cockpit environment control system powered by the piston engine, the present invention provides an ...
