Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1-3 , the present invention provides a variable-frequency air-cooled chiller with natural cooling, including an installation room 1 and a unit main body 2. The unit main body 2 is fixed inside the installation room 1 by bolts. One side of the installation room 1 is inlaid and fixed with an extension pipe 3. One side of the extension pipe 3 extends to the outdoor position. The outside of the extension pipe 3 is fixed with a temperature control switch 4 through a mounting bracket. The model of the temperature control switch 4 is KSD9700. One side of the extension pipe 3 is movably sleeved with a movable cover 5. There is a fixing mechanism on one side of the movable cover 5 to facilitate fixing the position of the movable cover 5. A circular groove 10 is opened at the center position of the movable cover 5. A dust-proof net 6 is welded and fixed inside the circular groove 10. The dust-proof net 6 facilitates preventing dust and foreign objects from entering the inside of the extension pipe 3. One side of the movable cover 5 is welded and fixed with a connecting rod 7. There are two connecting rods 7, symmetrically fixed on both sides of the movable cover 5. One side of the connecting rod 7 is fixed with a circular frame 8 through a bolt. A fan 9 is fixed inside the circular frame 8 through a mounting bracket. The fan 9 is electrically connected to the temperature control switch 4. When in use, when the outside ambient temperature is lower than the set value of the temperature control switch 4, at this time, the temperature control switch 4 starts the fan 9, and the fan 9 drives the air flow, so that the cold outside air is sucked into the installation room 1 through the extension pipe 3, and the unit main body 2 is directly cooled by the cold air, improving the cooling effect.
[0020] The fixing mechanism includes an extension plate 11, a fixing screw 12 and a rotating block 13. The extension plate 11 is welded and fixed to one side of the movable cover 5. There are two extension plates 11, which are symmetrically fixed at the upper and lower sides of the movable cover 5, and the extension plate 11 extends towards the installation chamber 1. The fixing screw 12 passes through the center of the extension plate 11 by means of threads. The rotating block 13 is welded and fixed to one side of the fixing screw 12. The outer side of the rotating block 13 is surrounded by anti-slip lines that increase the outer friction. When in use, when the movable cover 5 is sleeved on the outer side of the extension pipe 3, at this time, the fixing screw 12 is rotated, so that the fixing screw 12 presses against the outer side of the extension pipe 3, and the position of the movable cover 5 is fixed by friction. When maintenance is required, at this time, the fixing screw 12 is rotated in the reverse direction, so that the fixing screw 12 moves away from the outer side of the extension pipe 3, and then the movable cover 5 can be removed. At the same time, the fan 9 can be removed through the connecting rod 7, which facilitates the maintenance work.
[0021] Working principle: When the external environmental temperature is lower than the set value of the temperature control switch 4 during use, at this time, the temperature control switch 4 starts the fan 9, and the fan 9 drives the air to flow, so that the cold air from the outside is inhaled into the installation chamber 1 through the extension pipe 3, and the main body 2 of the unit is directly cooled by the cold air, improving the cooling effect; when in use, when the movable cover 5 is sleeved on the outer side of the extension pipe 3, at this time, the fixing screw 12 is rotated, so that the fixing screw 12 presses against the outer side of the extension pipe 3, and the position of the movable cover 5 is fixed by friction. When maintenance is required, at this time, the fixing screw 12 is rotated in the reverse direction, so that the fixing screw 12 moves away from the outer side of the extension pipe 3, and then the movable cover 5 can be removed. At the same time, the fan 9 can be removed through the connecting rod 7, which facilitates the maintenance work.
