[0022] It should be noted that the terms used here are only for describing the specific implementation mode and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.
[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description.

[0032] In this embodiment, during use, the air inlet cover 21 on the air guide member 2 is fixedly connected to the air inlet end of the gas turbine body 1. Then, a plurality of air inlet spiral cylinders 22 on the outer wall of the air inlet cover 21 are respectively connected and assembled with the connecting spiral pipes 25.

The liquid inlet pipe 74 is connected and assembled with a second cooling member 7, a third cooling member 8, and a first cooling member 6 in sequence on the connecting spiral pipe 25 of the third air inlet member 5. Later, the temperature sensor 24 detects the external air temperature value. According to the detected air temperature, the controller 23 controls the opening and closing of the solenoid valves 26 on the connecting spiral pipes 23 of the first air inlet member 3, the second air inlet member 4, and the third air inlet member 5. When the temperature is relatively high, the solenoid valve 26 on the third air inlet member 5 is opened, and the air is gradually cooled through the second cooling member 7, the third cooling member 8, and the first cooling member 6, and the cooling effect is better. At the same time, when the temperature is high, the solenoid valve 26 on the second air inlet member 4 is opened, and the air is gradually cooled through the third cooling member 8 and the first cooling member 6. When the temperature is low, the solenoid valve 26 on the first air inlet member 3 is opened.
