Description

Technical Field

[0001] The utility model relates to the technical field of chillers, in particular to an energy-saving and environment-friendly air-cooled box-type industrial cooling chiller. Background Art

[0002] In the refrigeration industry, there are two types of chillers: air-cooled chillers and water-cooled chillers. According to the compressor, they are divided into screw chillers, vortex chillers, and centrifugal chillers. In terms of temperature control, they are divided into low-temperature industrial chillers and normal temperature chillers. Chillers are also called: freezers, refrigeration units, chillers, cooling equipment, etc. Because they are widely used in various industries, the requirements for chillers are also different. Its working principle is a multifunctional machine that removes liquid vapor through compression or heat absorption refrigeration cycle.

[0003] The patent specification with the announcement number CN220489514U discloses an air-cooled chiller, which includes a main body, a heat dissipation mechanism and a refrigeration mechanism. The heat dissipation mechanism is located at the upper end of the main body, and the refrigeration mechanism is located at the inner end of the main body. The main body includes a chiller body, a water tank and a water supply pipe. The water tank is fixedly installed at the right end of the lower end of the inner end of the chiller body. By installing the heat dissipation mechanism, the air flow speed is accelerated, the internal temperature is reduced, and the service life of the air-cooled chiller is extended. The protective net is convenient for preventing foreign objects from entering the installation frame and causing damage to the fan.

[0004] However, in the implementation of relevant technologies, it was found that the air-cooled chiller of the above design has the following problems: in the above technical solution, a heat dissipation mechanism is installed to speed up the air flow rate, cool the interior, and extend the service life of the air-cooled chiller. The protective net is convenient for preventing foreign matter from entering the installation frame and causing damage to the fan. Although a protective net is used on the top to filter foreign matter, it cannot block rainwater. For example, on rainy days, rainwater will enter the unit through the protective net, causing damage to internal parts. In view of this, an energy-saving and environmentally friendly air-cooled box-type industrial cooling chiller is provided to overcome the above defects. Utility Model Content

[0022] Reference Figure 1-Figure 4The utility model provides an energy-saving and environmentally friendly air-cooled box-type industrial cooling chiller: it includes a unit shell 1, an air inlet pipe 2 is fixed on the upper surface of the unit shell 1, a protective cover 3 is arranged above the air inlet pipe 2, four fixing bolts 4 are symmetrically installed on the upper surface of the protective cover 3, and the ends of the four fixing bolts 4 are threadedly connected with fixing columns 5 fixed to the air inlet pipe 2, a dustproof net 6 is installed on the inner wall of the protective cover 3, and the inner wall of the dustproof net 6 is tightly fitted with the outer wall of the air inlet pipe 2. A driving motor 7 is fixed inside the unit shell 1, and a heat dissipation fan blade 8 is fixed to the power output shaft of the driving motor 7. The heat dissipation fan blade 8 is driven to rotate by the driving motor 7, and the external air is sucked in through the dustproof net 6 between the air inlet pipe 2 and the protective cover 3 to perform a cooling operation. The protective cover 3 arranged on the air inlet pipe 2 can effectively reduce the situation where rainwater enters the unit, and the dustproof net 6 arranged can play a certain dustproof role.

The protective plate 9 plays a protective role. When the heat dissipation fan blade 8 rotates, it will drive the mounting frame 10 to rotate, thereby driving the cleaning mechanism to operate.

[0024] As a further implementation scheme of the above technical scheme: fixed plates 11 are fixed in the vertical direction at both ends of the mounting frame 10, and springs 12 are installed inside the fixed plates 11. The end of the spring 12 is abutted and connected with a movable rod 13. Under the action of the elasticity of the spring 12 itself, the movable rod 13 is pushed to move, so that the cleaning mechanism can better contact with the heat dissipation structure, thereby improving the cleaning effect.

[0025] As a further implementation scheme of the above technical scheme: the end of the movable rod 13 passes through the outer wall of the fixed plate 11 and is fixed with a cleaning brush 14, and a partition plate 18 is fixed in the horizontal direction inside the unit casing 1. The cleaning brush 14 and the spiral heat dissipation tube 15 fit tightly together, thereby cleaning impurities on the surface of the spiral heat dissipation tube 15, so that the air can better absorb the heat of the spiral heat dissipation tube 15.

[0026] In specific implementation, before using the energy-saving and environmentally friendly air-cooled box-type industrial cooling chiller, first place the unit casing 1 in a suitable position, drive the motor 7 to drive the heat dissipation fan blades 8 to rotate, and blow air downward, so that the external air is sucked in through the dustproof net 6 between the air inlet pipe 2 and the protective cover 3, and the sucked air is blown out to the outside through the inner side of the spiral heat dissipation pipe 15, so as to better cool down.

When the heat dissipation fan blades 8 rotate, they will drive the mounting frame 10 to rotate, thereby driving the two fixing plates 11 to rotate, and the The cleaning brush 14 and the spiral heat dissipation tube 15 fit closely together, thereby cleaning the impurities on the surface of the spiral heat dissipation tube 15, so that the air can better absorb the heat of the spiral heat dissipation tube 15. Under the action of the elasticity of the spring 12 itself, the movable rod 13 will be pushed to move, thereby pushing the cleaning brush 14 to better contact with the spiral heat dissipation tube 15, thereby improving the cleaning effect. The partition plate 18 provided can separate the heat dissipation structure and the refrigeration structure. By unscrewing the fixing bolts 4 on the protective cover 3, the fixing bolts 4 and the fixing columns 5 are separated, and the fixing of the protective cover 3 is released. In this way, the protective cover 3 can be disassembled to facilitate maintenance of the internal parts.

[0027] As a further implementation scheme of the above technical scheme: a spiral heat dissipation tube 15 is fixed on the upper surface of the partition plate 18, and the outer surface of the spiral heat dissipation tube 15 is tightly fitted with the inner wall of the cleaning brush 14. The medium that needs to dissipate heat enters the spiral heat dissipation tube 15 through the pipeline, thereby cooling the medium.

[0028] As a further implementation scheme of the above technical scheme: an exhaust mesh port 16 is fixed to the right side of the unit casing 1, and a baffle 17 is fixed to the outer wall of the unit casing 1 and close to the right side of the exhaust mesh port 16. The air carrying heat is discharged to the outside through the exhaust mesh port 16, and the baffle 17 can further play a waterproof role.

[0030] During specific implementation, the compressor 19 sucks in the medium and compresses it, the condenser releases heat, condenses it into liquid to produce cold air, and then enters the evaporator through the capillary tube for recycling. When the condenser cools the medium, the medium enters the spiral heat dissipation tube 15 through the pipeline, and the air carrying heat is discharged to the outside through the exhaust mesh port 16, and the baffle 17 provided can further play a waterproof role.
