Description

Technical Field

[0001] The utility model relates to the technical field of water cooling machines, in particular to an air-cooled water cooling machine. Background Art

[0002] A water chiller, also known as a chiller, is a cooling water device that can provide constant temperature, constant flow and constant pressure. Water chillers are divided into air-cooled chillers and water-type chillers. Air-cooled chillers are a common refrigeration equipment that mainly uses fan-assisted heat dissipation to reduce the temperature in industrial equipment or processes. The working principle of an air-cooled chiller is based on a refrigeration cycle. It includes a compressor, a condenser, an expansion valve and an evaporator. First, the compressor draws in low-temperature and low-pressure refrigerant, and then increases its temperature and pressure through compression. Next, the refrigerant enters the condenser and dissipates heat under forced convection with the outside air through the fan, causing the refrigerant to cool and condense into a liquid. Then, the liquid refrigerant is depressurized through the expansion valve and enters the evaporator, where it absorbs heat and evaporates into a gas. Finally, the refrigerant enters the compressor again and the cycle repeats.

[0003] At present, air-cooled chillers need regular maintenance during use. During the maintenance process, the filter needs to be replaced. The filter is used to collect solid impurities in the refrigeration system and smooth oil to avoid blockage of the system and capillaries, or the contraction valve, and ensure that the piping system of the chiller is unobstructed. However, the filter is currently located inside the air-cooled chiller case for use. Since it needs to be replaced frequently, the case needs to be disassembled for each replacement. This replacement process will cause some dust to enter the inside of the case, which is not conducive to the overall use environment. For this reason, we propose an air-cooled chiller. Utility Model Content

[0004] In view of the above problems, the present invention provides an air-cooled water-cooling machine, which has the effect of reducing the open space when replacing the filter device and preventing excessive dust from entering the interior of the machine body.

The sealing cover and the inspection port are both L-shaped, and the inner wall of the groove and the top surface of the protrusion are provided with two opposite threaded openings, and the inner wall of the threaded opening is threadedly connected with a first fastening bolt.

[0012] The beneficial effects of the utility model are:

[0020] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] Example:

[0022] like Figures 1-4As shown, an air-cooled water-cooling machine comprises an air-cooled water-cooling machine body 1, a condenser 4, a heat dissipation port 5, a water inlet 6, a water outlet 7, and a filter 8. A condenser 4 is provided on the upper part of the interior of the air-cooled water-cooling machine body 1. Two heat dissipation ports 5 are provided on the top surface of the condenser 4, and the heat dissipation ports 5 pass upward through the top surface of the air-cooled water-cooling machine body 1. The surface of the air-cooled water-cooling machine body 1 is connected to the water inlet 6 and the water outlet 7. A compressor, an expansion valve, a compressor, and a water pump are provided inside the air-cooled water-cooling machine body 1. The surface of the filter 8 is connected to the expansion valve and the condenser 4 respectively. A back plate 2 is detachably installed on the rear surface of the air-cooled water-cooling machine body 1. The four corners of the back plate 2 are connected to the air Threaded holes 24 are provided at the four corners of the surface of the cold water chiller body 1, and a second fastening bolt 25 is provided on the surface of the back plate 2, and the second fastening bolt 25 is threadedly engaged with the threaded hole 24. A fixing box 9 is fixedly installed on the side of the back plate 2 deviating from the air-cooled water chiller body 1, and a support seat 12 is fixedly installed on the bottom surface of the inner wall of the fixing box 9. The filter 8 is located on the top surface of the support seat 12. An inspection port 10 is provided on the top surface of the side of the fixing box 9 away from the back plate 2. A sealing cover 11 is removably installed at the opening of the inspection port 10. A support frame 3 is fixedly installed on the middle and upper part of the inner wall of the air-cooled water chiller body 1, and the condenser 4 is located on the top surface of the support frame 3, which is convenient for placing the condenser 4.

[0023] The working principle of the above technical solution is as follows:

[0024] When the device is working normally, the compressor sucks in low-temperature and low-pressure refrigerant, and then increases its temperature and pressure through compression. Then, the refrigerant enters the condenser 4, and dissipates heat with the outside air through forced convection at the heat dissipation port 5, so that the refrigerant is cooled and condensed into liquid. Then, the liquid refrigerant passes through the filter 8 and enters the expansion valve to reduce the pressure, and enters the evaporator, absorbs heat and evaporates into gas. Finally, the refrigerant enters the compressor again, and the cycle repeats. After a long period of use, the filter 8 needs to be inspected and replaced. You only need to pull the sealing cover 11 outward horizontally from the opening of the inspection port 10, and then the filter 8 can be disassembled at the opening of the inspection port 10.

[0025] In another embodiment, Figure 3 As shown, a connecting tube 13 is inserted into the inner wall of the opening of the heat dissipation port 5, a first dustproof net 14 is fixedly installed in the middle of the inner wall of the connecting tube 13, a mounting opening 15 is opened at the center of the surface of the first dustproof net 14, a heat dissipation fan 16 is installed on the inner wall of the mounting opening 15, and a second dustproof net 17 is fixedly installed at the top of the connecting tube 13.

[0026] By providing the connecting tube 13 , the first dustproof net 14 , the mounting port 15 and the second dustproof net 17 , the cooling fan 16 can be used with a multi-layer dustproof effect, thereby preventing external dust from entering the air-cooled water-cooled machine body 1 and affecting the heat dissipation of the condenser 4 .

[0027] In another embodiment, Figure 2 and Figure 3 As shown, the top surface of the fixed box 9 is provided with two opposite grooves 19, and two opposite protrusions 18 are fixedly installed on one side of the top of the sealing cover 11. The protrusions 18 are tightly fitted with the inner wall of the groove 19. The sealing cover 11 and the inspection port 10 are both L-shaped. The inner wall of the groove 19 and the top surface of the protrusion 18 are provided with two opposite threaded openings 20. The inner wall of the threaded opening 20 is threadedly connected with a first fastening bolt 21. By providing the groove 19, the installation of the sealing cover 11 can be made to fit the top surface of the fixed box 9. Effect, in addition, the L-shaped setting can make the sealing cover 11 fit the opening of the inspection port 10 more conveniently. After the protrusion 18 is located on the inner wall of the groove 19, the sealing cover 11 can be located on the inner wall of the opening of the inspection port 10, and the two side walls of the sealing cover 11 are fixedly installed with sealing strips 23.
