Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and particularly relates to an integrated water-cooled air conditioner. Background Art

[0002] As disclosed in a water-cooled air conditioner with the Chinese utility model patent application number 202321710777.8, it mainly includes a frame body, a fan, an evaporator, a shell-and-tube heat exchanger, a gas-liquid separator, a compressor, a coolant curtain, a water pump, a water storage tank, and a water inlet pipe and a water outlet pipe respectively connected to the shell-and-tube heat exchanger.

[0003] Among them, the shell-and-tube heat exchanger belongs to the most widely used traditional heat exchanger. When the refrigerant flows from the output end of the compressor to the evaporator, it needs to pass through the shell-and-tube heat exchanger for heat exchange first. The shell-and-tube heat exchanger includes a copper tube for the refrigerant to flow through. When the refrigerant flows from the compressor to the copper tube, the copper tube absorbs heat and heats up. After the coolant is input into the shell-and-tube heat exchanger and fully contacts with the copper tube and absorbs the heat on the copper tube, it flows out of the shell-and-tube heat exchanger, thereby realizing heat exchange and cooling the copper tube and the refrigerant therein.

[0004] During the heat exchange process of the coolant, since the copper tube absorbs the heat of the coolant and its temperature rises, at this time, the originally dissolved Ca(HCO3)2 and Mg(HCO3)2 in the water precipitate CO2 under the action of temperature to form slightly water-soluble CaCO3 and MgCO3. When these crystals continuously deposit in the shell-and-tube heat exchanger, hard water scale is formed, which not only affects the heat exchange efficiency but also increases the energy consumption. To avoid these problems, the shell-and-tube heat exchanger needs to be cleaned regularly.

[0005] However, the internal structure of the shell-and-tube heat exchanger is relatively complex, and it is difficult to clean the water scale inside it thoroughly with ordinary cleaning, resulting in poor cleaning efficiency; regularly replacing the new heat exchanger has the problem of high maintenance cost. Summary of the Utility Model

[0006] The main purpose of the utility model is to propose an integrated water-cooled air conditioner, aiming to solve the deficiencies mentioned in the above background art.

[0007] To achieve the above purpose, the utility model proposes an integrated water-cooled air conditioner, including a frame body, a fan, an evaporator, a compressor, and a heat exchange mechanism, characterized in that: the heat exchange mechanism includes a water pool, a water pump, a water curtain, and at least one cooling pipe. The output end of the compressor and the input end of the evaporator are respectively connected to both ends of the cooling pipe. The cooling pipe is immersed in the coolant in the water pool for heat exchange. The water pump is used to pump the coolant in the water pool and send it to the water curtain for heat dissipation and cooling, and then flow back into the water pool.

[0008] Preferably, when the water tank is provided with a plurality of the cooling pipes, the same ends of the plurality of cooling pipes are communicated with each other.

[0009] Preferably, the water tank is provided with three, six or nine of the cooling pipes.

[0010] Preferably, the cooling pipe is a straight pipe, an L-shaped pipe or a serpentine pipe.

[0011] Preferably, at least one water flow channel is formed inside the water tank by a plurality of partition plates. The cooling pipe is adapted to the shape of the water flow channel. The front end of the water flow channel is close to the output end of the compressor, and the water pump is arranged at the end of the water flow channel.

[0012] Preferably, the water flow channel is linear, L-shaped or serpentine.

[0013] Preferably, the partition plate further cooperates with the water tank to form an isolation area. The bottom of the water curtain is located in the isolation area, and the isolation area is communicated with the front section of the water flow channel.

[0014] Preferably, the frame body is in a box shape. The evaporator and the fan are arranged at the upper part of the frame body, and the compressor and the heat exchange mechanism are arranged at the lower part of the frame body. The frame body is further provided with an air inlet pipe, an air outlet pipe and an exhaust fan. The exhaust fan is used for sucking the air at the lower part of the frame body and discharging the sucked air to the outside through the air outlet pipe. One end of the air inlet pipe is communicated with the upper part of the frame body, and the other end is communicated with the outside. When the fan works, it can suck the uncooled air from the outside through the air inlet pipe, pass through the evaporator and then send it into the room.

[0015] Preferably, the cooling pipe is made of copper, aluminum or stainless steel.

[0016] Based on the existing integrated water-cooled air conditioner, the technical solution of the present invention cancels the shell-and-tube heat exchanger, and replaces the original shell-and-tube heat exchanger with a heat exchange mechanism including a water tank, a water pump, a water curtain and at least one cooling pipe. Among them, the cooling pipe is immersed in the cooling liquid in the water tank, and both ends are respectively connected to the output end of the compressor and the input end of the evaporator. The cooling liquid in the water tank can be pumped to the water curtain by the water pump and then flow back to the water tank to realize circulation. When working, during the process of the compressor delivering the refrigerant to the evaporator, heat exchange is carried out between the cooling pipe and the cooling liquid in the water tank to realize cooling. At the same time, the cooling liquid in the water tank is pumped to the water curtain by the water pump for heat dissipation and cooling, and then flows back to the water tank to realize the circulating cooling of the cooling liquid to ensure the stable cooling of the cooling pipe. Compared with the traditional one, the heat exchange mechanism of the present invention has a simple structure, is easy to clean, has better cleaning efficiency, low cost, and small maintenance and replacement costs.

[0022] The present utility model provides an integrated water-cooled air conditioner.

[0023] In the embodiments of the present utility model, as Figures 1 to 2 shown, the integrated water-cooled air conditioner includes a frame 1, a fan 2, an evaporator 3, a compressor 4, and a heat exchange mechanism, and is characterized in that: the heat exchange mechanism includes a water tank 5, a water pump 6, a water curtain 7, and at least one cooling pipe 8. The output end of the compressor 4 and the input end of the evaporator 3 are respectively connected to both ends of the cooling pipe 8. The cooling pipe 8 is immersed in the coolant in the water tank 5 for heat exchange. The water pump 6 is used to extract the coolant in the water tank 5 and send it to the water curtain 7 for heat dissipation and cooling, and then flow back into the water tank 5.

[0024] Specifically, when there are multiple cooling pipes 8 in the water tank 5, the same ends of the multiple cooling pipes 8 are connected to each other.

[0025] Specifically, the water tank 5 is provided with three, six or nine of the cooling pipes 8.

[0026] Specifically, the cooling pipe 8 is a straight pipe, an L-shaped pipe or a serpentine pipe.

[0027] Specifically, at least one water flow channel is formed inside the water tank 5 through a plurality of partition plates 51. The cooling pipe 8 is adapted to the shape of the water flow channel. The front end of the water flow channel is close to the output end of the compressor 4, and the water pump 6 is arranged at the end of the water flow channel. When there are multiple water flow channels, the same ends of the multiple water flow channels are connected to each other, and at least one of the cooling pipes 8 is arranged in each water flow channel.

[0028] Specifically, the water flow channel is linear, L-shaped or serpentine.

[0029] Specifically, the partition plate 51 also cooperates with the water tank 5 to form an isolation area 52. The bottom of the water curtain 7 is located in the isolation area 52, and the isolation area 52 is communicated with the front section of the water flow channel. That is, the coolant in the isolation area 52 can flow into the front section of the water flow channel, avoiding the water pump 6 from pumping the coolant that has just flowed back from the water curtain 7 to the water tank 5 and has not exchanged heat with the cooling pipe 8.

[0030] Specifically, the water tank 5 is made of metal. Preferably, a metal with strong heat absorption ability is used to absorb the heat of the coolant. Similarly, the partition plate 51 is also made of a metal product with strong heat absorption ability.

[0031] Specifically, the frame body 1 is in a box shape. The evaporator 3 and the fan 2 are arranged at the upper part of the frame body 1, the compressor 4 and the heat exchange mechanism are arranged at the lower part of the frame body 1. The frame body 1 is also equipped with an air inlet pipe, an air outlet pipe and an exhaust fan 9. The exhaust fan 9 is used to suck the air at the lower part of the frame body 1 and cooperate with the air outlet pipe to discharge the sucked air to the outside. One end of the air inlet pipe is communicated with the upper part of the frame body 1, and the other end is communicated with the outside. When the fan 2 works, it can suck the uncooled air from the outside through the air inlet pipe and send it into the room after passing through the evaporator 3. This avoids the problem of poor refrigeration effect caused by the fan 2 repeatedly sucking the cooled air in the room during operation.

[0032] Specifically, the cooling pipe 8 is made of copper, aluminum or stainless steel.

[0033] It should be noted that the other structures of the integrated air conditioner can refer to the prior art. For example, a water-cooled air conditioner disclosed in the Chinese Utility Model Patent Application No. 202321710777.8 will not be elaborated here.

[0034] Based on the existing integrated water-cooled air conditioner, the technical solution of the present utility model cancels the tube-in-tube heat exchanger, and replaces the original tube-in-tube heat exchanger with a heat exchange mechanism including a water pool, a water pump, a water curtain and at least one cooling pipe. Among them, the cooling pipe is immersed in the coolant in the water pool and is respectively connected to the output end of the compressor and the input end of the evaporator at both ends. The coolant in the water pool can be circulated by being pumped to the water curtain by the water pump and then flowing back to the water pool. During operation, when the compressor transports the refrigerant to the evaporator, heat exchange is carried out between the cooling pipe and the coolant in the water pool to achieve temperature reduction. At the same time, the coolant in the water pool is pumped to the water curtain by the water pump for heat dissipation and temperature reduction, and then flows back to the water pool to realize the cyclic temperature reduction of the coolant to ensure the stable temperature reduction of the cooling pipe. Compared with the traditional one, the heat exchange mechanism of the present utility model has a simple structure, is easy to clean, has better cleaning efficiency, low cost, and low maintenance and replacement costs.

[0035] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the description and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
