Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, in particular to an anti-corrosion air-cooled water chiller. Background Art

[0002] Air-cooled chillers are one of the chiller models. They cool water at room temperature to a certain temperature through the compressor of the chiller to strengthen the cooling of molds or machines. They are used as a single machine. The heat dissipation device is a built-in fan. There are three main interconnected systems: refrigerant circulation system, water circulation system, and electrical automatic control system. The refrigerant circulation system of the chiller makes the liquid refrigerant in the evaporator absorb the heat from the water and begin to evaporate. Ultimately, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates and becomes gaseous, which is then sucked in and compressed by the compressor. The gaseous refrigerant releases heat through the condenser and condenses into liquid. After throttling through the thermal expansion valve, it becomes a low-temperature and low-pressure refrigerant and enters the evaporator, completing the refrigerant circulation process.

[0003] However, when the existing air-cooled chiller is working, the water in the chiller will contain impurities after a long period of circulation. This impurity may come from the water itself or from debris generated by the friction of the internal components of the machine. If the water cannot be filtered, scale will easily accumulate inside the chiller, which is difficult to clean. For this reason, we have designed an anti-corrosion air-cooled chiller to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and to propose an anti-corrosion air-cooled chiller, which can block and buffer the liquid, reduce the direct impact of the liquid on the filter screen so that impurities enter the filter shell, and the filter screen can reduce the impurities in the water entering the water inlet pipe, thereby reducing the scaling phenomenon in the air-cooled chiller body, and the water pump, evaporator and connecting pipes and other components are made of 304 stainless steel, so that when the liquid circulates in the pipe, there will be no rust impurities in the water, which can ensure the cleanliness of the water channel and the corrosion of the pipe, thereby ensuring the normal operation of the unit.

[0008] Preferably, an annular waterproof gasket is embedded in the outer side wall of the filter frame, and a plurality of pull blocks are fixedly connected to the side wall of one end of the filter frame close to the cover body.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. This anti-corrosion air-cooled chiller adds liquid into the filter shell through the water inlet connecting pipe. The liquid impacts the buffer plate, which can block and buffer the liquid, reducing the direct impact of the liquid on the filter screen so that impurities enter the filter shell.

[0023] A filter screen 7 is installed through the filter frame 6, and the filter screen 7 can filter the liquid entering the filter housing 3 to reduce the formation of scale. An annular waterproof gasket is embedded in the outer wall of the filter frame 6 to ensure the sealing between the filter frame 6 and the inner wall of the filter housing 3, so that the liquid can enter the water inlet pipe 2 after being filtered by the filter screen 7. A plurality of pull blocks are fixedly connected to the side wall of one end of the filter frame 6 close to the cover body 9, so as to facilitate pulling the filter frame 6 outward from the filter housing 3;

[0024] The filter housing 3 is detachably connected with a cover 9, which is connected to the filter housing 3 by a plurality of screws 8, so that the cover 9 can be easily installed and removed. The side wall of the filter housing 3 is embedded with an annular rubber sealing gasket 10 that abuts against the inner side wall of the cover 9. The annular rubber sealing gasket 10 can ensure the sealing between the cover 9 and the filter housing 3, and avoid water leakage at the connection between the cover 9 and the filter housing 3.

[0025] A water inlet connecting pipe 12 is installed through the cover body 9 in a sealed manner. The inner side wall of the cover body 9 is provided with a buffer assembly opposite to the water inlet connecting pipe 12.

After cleaning, the limit rod 5 passes through the filter frame 6 and puts the filter frame 6 back into the filter shell 3. The cover body 9 can be installed on the filter shell 3 through the screws 8, and the push rod 11 is against the side wall of the filter frame 6. The annular support plate 4 and the push rod 11 work together to stably fix the filter frame 6.
