[0045] Working principle:

[0046] During use, the bolts on the first flange ring are opened, and then the flow guide auxiliary shell 201 is unfolded. According to the requirements, the corresponding number of wind baffles 209 is arranged in the installation groove 208, and then the flow guide auxiliary shell 201 is closed, so that the positioning strip 213 is embedded in the positioning groove 214, and the third air inlet hole 212 is used to extrude and fix the wind baffle 209. Then the bolts on the first flange ring are installed, so as to realize the switching from "full circumference air inlet" to "local air inlet".

[0047] At the same time, according to the demand, the corresponding number of air inlets 107 is opened for ventilation, and the airflow first enters the inside of the flow guide end shell 106 from the air inlet 107, and then is introduced along the support cylinder 301 and the air inlet curved surface 302 to the surface of the pressure gas outer ring 105. At this time, the space between the pressure gas outer ring 105 and the support cylinder 301 is reduced, and the unevenly distributed airflow in the air inlet 107 will be compressed to a certain extent, so that the airflow cannot pass through at the same time. This forces the airflow to pass through other positions between the pressure gas outer ring 105 and the support cylinder 301, so that the airflow is more evenly distributed around the surface of the support cylinder 301. Then the airflow passes between the pressure gas inner ring 304 and the flow guide main shell 101 in the same way, and also makes the airflow more evenly distributed around the surface of the support cylinder 301. Then the uniform airflow is uniformly distributed between the flow guide baffles 402 along the pressure gas flow guide ring 401 and is transported inward. Due to the blocking of the flow guide baffles 402, the airflow between the flow guide baffles 402 does not interfere with each other, so that the airflow evenly distributed around the surface of the support cylinder 301 can reach the other end uniformly. Then the airflow passes from the inside of the corresponding second air inlet hole 207 which is not covered by the wind deflector 209, and then the airflow passes through the fire-retardant net 205 and is discharged into the turbine. Thus, it can be ensured that the airflow passing through the second air inlet hole 207 is uniform when the number of air inlets 107 is one, two or three.

[0048] First, one end of the first electromagnetic switch valve 508 is connected with the external drain pipe, the input end of the liquid pump 503 is connected with the cold water pipe, and the input end of the second electromagnetic switch valve 512 is connected with the fire extinguishing agent pipeline. When dissipating heat, the first electromagnetic switch valve 508 is opened, and the liquid pump 503 is started. The liquid pump 503 pumps cold water into the first conversion seat 501, and then the cold water enters the pressure gas outer ring 105 and the pressure gas flow guide ring 401 along the water inlet elbow 505. At this time, the flow guide baffles 402 guide heat into the pressure gas flow guide ring 401, and the flow guide main shell 101 and the support cylinder 301 guide heat into the pressure gas outer ring 105 and the pressure gas flow guide ring 401. The cold water passing through the two absorbs heat and becomes hot water, so that the water flow reaches from the lower part to the upper part of the pressure gas outer ring 105 and the pressure gas flow guide ring 401, then enters the second conversion seat 506, and finally is discharged from the first electromagnetic switch valve 508, thereby realizing continuous heat dissipation inside the device. When extinguishing fire, the second electromagnetic switch valve 512 is opened after receiving a signal from an external sensor or an external controller. At this time, the fire extinguishing agent enters the connecting pipe 513 from the second electromagnetic switch valve 512, and then enters the inside of the flow guide main shell 101. Then the second flow guide curved surface along the surface of the pressure gas inner ring 304 enters between the flow guide main shell 101 and the support cylinder 301 to cool and extinguish the inside.
