Embodiment 1

[0023] Such as figure 1 As shown, the air-cooling system for a bench test of a small rotor engine disclosed in this embodiment includes a cooling fan blade 1 , an air flow rear cover 2 , a bench tooling plate 3 , a ventilation pipe 4 , a fan 5 , and a rotor engine 6 .

[0024] The cooling fan blades 1 are used to generate fast and continuous airflow, and conduct the heat of the front end cover of the rotary engine 6 into the air. The cooling fan blade 1 is installed at the end of the eccentric shaft of the rotor motor 6, and coaxially with the eccentric shaft, it performs a stable rotational motion at the same time, and the speed is consistent with the output speed of the eccentric shaft of the rotor motor 6. The cooling fan blade 1 and the rotor engine 6 rotate at the same speed to ensure that its heat dissipation function is adapted to the heat dissipation requirements of the rotor engine 6 at different speeds, that is, the heat dissipation demand of the rotor engine 6 is la...

Abstract

The invention discloses an air cooling system for mini rotor engine rig test, and belongs to the technical field of mini rotor engine test. The system comprises air cooling fan blades, a rear airflowcover, a rig tool plate, a ventilation duct, a blower fan and a rotor engine. Air cooling is carried out on the engine via forward and backward cooling airflow, the rear airflow cover is provided withan airflow channel position according to the body temperature field, cooling conditions needed by different parts of the engine in the operation process are met, and the structure is simplified to ensure that the system is efficient and compact. The forward cooling airflow is provided by the air cooling fan blades, and the backward cooling airflow is provided by the blower fan. The air cooling fan blades and the rotor engine rotate at the same speed so that a heat radiation function can be adapted to heat radiation requirements at different rotating speeds of the rotor engine, energy consumption is reduced, and the cooling fan blades mounted coaxially in the front end replace a large blower fan so that the space is saved, the cost is reduced, and noise in a lab is reduced.

Description

technical field [0001] The invention relates to auxiliary equipment for small rotor engines, in particular to an air-cooling system for bench tests based on small rotor engines, and belongs to the technical field of small rotor engine tests. Background technique [0002] During the working period of the rotary engine, due to the combustion of the combustible mixture, a large amount of heat is generated, and the temperature of the gas in the cylinder is very high, and part of the heat is transferred to the front and rear end covers, rotors, cylinders and other components. Even affecting the normal operation of the rotary engine, it is necessary to adopt a certain cooling method to dissipate the excess heat borne by the parts into the air. For rotary engines with small displacement, due to their small size, there are no cooling water passages and cooling oil passages in the body design, so air cooling is generally used. In the bench test of the engine, it is necessary to have...
