Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to an industrial water-cooled air cooler. Background Art

[0002] In industrial production, many devices generate significant amounts of heat during operation. Failure to dissipate this heat promptly and effectively can lead to equipment overheating, impacting performance and lifespan, and even causing safety incidents. With the continuous development of industry, the power and density of industrial equipment continue to increase, placing increasing demands on cooling systems. In some cases, traditional air cooling methods are no longer sufficient to meet industrial cooling needs, leading to the emergence of water-cooled air chillers.

[0003] Traditional air-cooling relies primarily on air flow to remove heat. However, air cooling has limited effectiveness, particularly in high-temperature environments where the air itself is hot, significantly reducing cooling capacity. Furthermore, air-cooled equipment is typically bulky and noisy, making it unsuitable for industrial locations with strict space and noise requirements.

[0004] During use, the refrigerant that passes through the evaporator and returns to the compressor pipeline is not cooled or dissipated, resulting in poor cooling effect during the subsequent cycle refrigeration process, affecting the subsequent cooling effect. Utility Model Content

[0005] The purpose of the present invention is to provide an industrial water-cooled air cooler to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An industrial water-cooled air cooler comprises a shell, an air outlet cavity and an installation cavity are provided in the shell; a compressor and a condenser are provided in the installation cavity, an evaporator is provided in the air outlet cavity, and the compressor and the evaporator are connected by a delivery copper pipe; the delivery copper pipe passes through the condenser, and the condenser circulates and cools the high-temperature coolant in the delivery copper pipe to dissipate heat; a circulating water tank is provided on the side of the shell, and a circulating water pump is provided on the circulating water tank; the water outlet end of the condenser is connected to the circulating water tank, and the circulating water pump is connected to the water inlet end of the condenser; the evaporator and the compressor are connected by a recovery copper pipe; the delivery copper pipe is provided with an expansion valve on one side of the evaporator; an air outlet is provided above the shell at the air outlet cavity, and a blower for discharging cold air to the outside is provided at the air outlet.

[0008] According to a further technical solution, the condenser is in the shape of a spiral coil, and the delivery copper tube is located in the middle of the spiral coil condenser.

[0010] According to a further technical solution, the evaporator has a three-sided structure.

[0011] According to a further technical solution, an air outlet curtain is provided above the shell at the air outlet.

[0012] Beneficial effects of the utility model:

[0013] The utility model compresses the refrigerant into a high-temperature and high-pressure refrigerant coolant through the operation of the compressor, and then transports the high-temperature and high-pressure refrigerant coolant to the evaporator through the delivery copper pipe, and then transports it to the evaporator through the condenser, and converts the high-temperature and high-pressure refrigerant coolant into a low-temperature refrigerant coolant through the condenser, and then continues to transport it to the expansion valve through the delivery copper pipe. The expansion valve transports the low-temperature refrigerant coolant to the evaporator, and the evaporator exhausts the cooled air to the outside into the air outlet cavity, and the cold gas is discharged to the outside through the air outlet fan, thereby achieving the effect of emitting cold air, and the low-temperature refrigerant coolant discharged from the evaporator is transported to the compressor through the recovery copper pipe for compression, forming a cycle;

[0014] The high-temperature, high-pressure refrigerant coolant transported through the copper tubes cools and dissipates heat, resulting in a lower temperature for the coolant entering the condenser. The spiral condenser's increased contact area significantly increases the contact area between the copper tubes and the circulating water. Compared to straight tubes, the coil's curved structure allows more of the copper tube surface to come into contact with the circulating water, effectively transferring heat to the water and achieving rapid heat dissipation. Heat transfer is also enhanced: As the circulating water flows through the spiral coils, the coil's shape creates a certain amount of turbulence, enhancing convective heat transfer between the water and the copper tubes. This turbulence disrupts the boundary layer, increasing the heat transfer coefficient and significantly improving heat dissipation efficiency.

[0015] Other features and advantages of the present invention will be described in detail in the subsequent detailed description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Please refer to Figure 1-4 As shown; the utility model provides a technical solution for an industrial water-cooled air cooler: an industrial water-cooled air cooler, comprising a shell 1, wherein an air outlet cavity 11 and an installation cavity 12 are provided in the shell 1; a compressor 2 and a condenser 3 are provided in the installation cavity 12, an evaporator 4 is provided in the air outlet cavity 11, and the compressor 2 and the evaporator 4 are connected by a conveying copper tube 7; the conveying copper tube 7 passes through the condenser 3, and the condenser 3 circulates and cools the high-temperature coolant in the conveying copper tube 7 to dissipate heat; the evaporator 4 and the compressor 2 are connected by a recovery copper tube 6; the conveying copper tube 7 is provided with an expansion valve 5 on one side of the evaporator 4; an air outlet 13 is provided above the shell 1 at the air outlet cavity 11, and an air outlet fan 14 for discharging cold air to the outside is provided at the air outlet 13.

[0023] During use, the refrigerant is compressed into a high-temperature and high-pressure refrigerant coolant by the compressor 2, and then the high-temperature and high-pressure refrigerant coolant is transported to the evaporator 4 through the delivery copper tube 7, and then transported to the evaporator 4 through the condenser 3, and the high-temperature and high-pressure refrigerant coolant is converted into a low-temperature refrigerant coolant by the condenser 3, and then continued to be transported to the expansion valve 5 through the delivery copper tube 7. The expansion valve 5 transports the low-temperature refrigerant coolant to the evaporator 4, and the evaporator 4 exhausts the cooled air to the air outlet cavity 11, and the cold gas is discharged to the outside through the air outlet 13 by the air blower 14, thereby achieving the effect of emitting cold air, and the low-temperature refrigerant coolant discharged from the evaporator 4 is transported to the compressor 2 through the recovery copper tube 6 for compression, forming a cycle;

[0024] The high-temperature, high-pressure refrigerant coolant transported by the copper tube 7 is cooled and dissipated, making the temperature of the coolant entering the condenser 3 lower. The spiral condenser 3 can increase the contact area: the spiral coil design greatly increases the contact area between the copper tube and the circulating water. Compared with straight tubes, the curved structure of the coil allows more of the copper tube surface to fully contact the circulating water, thereby more effectively transferring heat to the circulating water and achieving rapid heat dissipation; enhancing the heat transfer effect: when the circulating water flows in the spiral coil, the shape of the coil will produce a certain turbulence effect, which enhances the convective heat transfer between the water and the copper tube. This turbulence can destroy the boundary layer, increase the heat transfer coefficient, and significantly improve the heat dissipation efficiency.

[0025] In this embodiment, referring to Figure 3 As shown, the condenser 3 is in the shape of a spiral coil, and the copper delivery tube 7 is located inside the spiral coil condenser 3. The copper delivery tube 7 located at the condenser 3 is also in the shape of a spiral coil, and the condenser 3 is wrapped around the outside of the copper delivery tube 7 and is adapted to the copper delivery tube 7. The spiral coil condenser 3 can increase the heat dissipation area and speed up the heat dissipation time when dissipating the high-temperature coolant refrigerant in the copper delivery tube 7.

[0026] The spiral coil shape of the condenser 3 lengthens the cooling water's flow path within the condenser 3, extending the contact time between the water and the condenser 3 tube walls. This means the high-temperature coolant refrigerant has more opportunities to absorb the cold air from the circulating water in the condenser 3, thereby improving heat transfer efficiency and enabling the condenser 3 to dissipate heat more quickly and effectively. The water flowing through the spiral coil generates strong turbulence. This turbulence thoroughly mixes the various components of the water, reducing the thickness of the boundary layer and thus improving the heat transfer coefficient between the water and the condenser 3 tube walls.

[0027] Compared to laminar flow, turbulent flow transfers heat more quickly and efficiently, helping to improve the heat dissipation efficiency of condenser 3. The spiral coil structure ensures relatively uniform distribution of cooling water throughout the coil. This uniform water flow distribution ensures that all parts of condenser 3 are adequately cooled, preventing localized overheating or undercooling, and dissipating heat more evenly from the high-temperature coolant refrigerant within copper tube 7.

[0028] In this embodiment, referring to Figure 1 As shown, a circulating water tank 8 is provided beside the housing 1, and a circulating water pump 80 is provided on the circulating water tank 8. The water outlet of the condenser 3 is connected to the circulating water tank 8, and the circulating water pump 80 is connected to the water inlet of the condenser 3. It should be noted that a cooling plate is provided in the circulating water tank 8 to cool the water in the circulating water tank 8 in real time.

[0029] During use, the circulating water pump 80 works to extract water from the circulating water tank 8 and transport it to the water inlet of the condenser 3. The condenser 3 cools the high-temperature and high-pressure refrigerant coolant in the copper tube 7. The cooled water then returns to the circulating water tank 8, thus completing a cooling cycle.

[0030] In this embodiment, the evaporator 4 is a three-sided structure. When the cold air is discharged outwards through the air outlet fan 14, more cold air can be output outwards, so that the cold air can be discharged outwards better to perform heat dissipation work.

[0031] In this embodiment, referring to Figure 4 As shown, an air outlet curtain 9 is provided above the housing 1 at the air outlet 13; the air outlet curtain 9 can change the direction of the air outlet and adjust the wind direction of the cold air discharged forward as needed.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
