[0024] The setting presses the first limit frame 12 so that the first limit frame 12 squeezes the spring 13, so that the first limit frame 12 slides into the installation groove 101, and then the connecting pipe 14 is sleeved on the surface of the air outlet pipe 11, and then the connecting hook 15 is moved so that the connecting hook 15 and the connecting pipe 14 rotate relative to each other, so that the connecting hook 15 and the fixing buckle 111 are engaged, and then the connecting pipe 14 is pulled to drive the connecting hook 15 to be engaged with the inside of the fixing buckle 111, and then the first limit frame 12 is released, and the second limit frame 121 is used to limit the first limit frame 12, so that the first limit frame 12 cannot directly slide out of the installation groove 101, thereby increasing the connection stability between the first limit frame 12 and the installation groove 101, so that the first limit frame 12 uses the elastic force of the spring 13 to limit the connecting hook 15, and the splicing of the air outlet pipe 11 and the connecting pipe 14 can be completed.

[0025] The side wall of the air cooler 1 is provided with an installation frame 16, and the side wall of the air cooler 1 is provided with an inspection panel 3, which is slidably connected to the installation frame 16 and can be quickly disassembled by directly pulling upwards, thereby further increasing the inspection efficiency, and has a simple structure and low use cost.

[0026] The connecting hook 15 and the fixing buckle 111 are snap-connected, and the end of the connecting hook 15 is an arc-shaped structure. The connecting hook 15 fits the inner wall of the fixing buckle 111 and is used for splicing the air outlet pipe 11 and the connecting pipe 14 .
