Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and in particular to a natural cooling and evaporative cooling water cooling device. Background Technology

[0002] Most cooling systems in small and medium-sized data centers use air-cooled air conditioners, which have the following main disadvantages:

[0003] 1. High condensing temperature, using air cooling, with condensing temperatures all above 50℃;

[0004] 2. Low energy efficiency; the energy efficiency ratio of air-cooled systems is generally lower than 3.

[0005] 3. High power consumption: The computer room needs to be cooled all year round, and the compressor also needs to run all year round, resulting in high energy consumption.

[0006] Some data centers use water-cooled units for cooling, but the main disadvantages are:

[0007] 1. Water is used as the heat transfer medium, which is prone to freezing in winter;

[0008] 2. The cooling tower adopts an open system, which makes the water quality susceptible to pollution. Scale buildup is also prone to occur on the heat exchanger and pipes, thus affecting the heat dissipation of the entire system.

[0009] 3. There is no device for utilizing natural cooling; the compressor runs year-round, resulting in high energy consumption. Utility Model Content

[0053] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Please refer to Figure 1This utility model provides a natural cooling and evaporative cooling water cooling device, including an indoor cooling mechanism 1, an outdoor cooling mechanism 3, and a refrigeration mechanism 2;

[0055] The indoor cooling mechanism 1 includes an indoor housing 11, a blower 13, and a heat exchange coil 12.

[0056] The blower 13 and the heat exchange coil 12 are both installed inside the indoor enclosure 11;

[0057] The outdoor cooling mechanism 3 includes an outdoor housing 31, a heat exchanger 32, and an exhaust fan 33.

[0058] The outlet of the heat exchanger 32 is connected to the inlet of the heat exchange coil 12 through the first pipe 4, and a first control valve 10 is installed on the first pipe 4.

[0059] The inlet of the heat exchanger 32 is connected to the outlet of the heat exchange coil 12 through the second pipe 5, and a second control valve 11 is installed on the second pipe 5.

[0060] The refrigeration mechanism 2 includes a compressor 23, a condenser 22, an electronic expansion valve 21, and an evaporator 24;

[0061] The compressor 23, condenser 22, electronic expansion valve 21 and evaporator 24 are connected in a loop through pipelines to form a refrigeration cycle.

[0062] One end of the condenser 22 is connected to the first pipeline 4 through the third pipeline 6, and the third control valve 12 is installed on the third pipeline 6. The other end of the condenser 22 is connected to the second pipeline 5 through the fourth pipeline 7.

[0063] One end of the evaporator 24 is connected to the first pipe 4 through the fifth pipe 8, and the other end of the evaporator 24 is connected to the second pipe 5 through the sixth pipe 9, and a fourth control valve 13 is installed on the sixth pipe 9.

[0064] It should be noted that the heat exchange method for the glyoxal liquid in the pipeline by the evaporator 24 and the condenser 22 is to use the heat exchanger 32.

[0065] In this embodiment, an air inlet is provided on the lower side of the indoor housing 11, an air outlet is provided on the upper side of the indoor housing 11, the heat exchange coil 12 is installed inside the top of the indoor housing 11, and the blower 13 is installed inside the bottom of the indoor housing 11.

[0066] In this embodiment, an air outlet is provided on the top of the outdoor housing 31, the heat exchanger 32 is installed inside the top of the outdoor housing 31, and a cooling component 34 is provided inside the bottom of the outdoor housing 31. The cooling component 34 includes a wet curtain, a spray pipe, a delivery pump, and a water tank.

[0067] The wet curtain is installed at the air inlet of the outdoor housing 31;

[0068] The spray pipe is installed above the wet curtain and is used to spray water onto the wet curtain;

[0069] The water tank is installed inside the bottom of the outdoor enclosure 31;

[0070] The delivery pump is connected to the water tank and the spray pipe respectively, and delivers the water in the water tank to the spray pipe;

[0071] When in use, hot outdoor air comes into contact with water as it passes through the wet curtain. The water evaporates and absorbs heat from the air, lowering the air temperature. As the air temperature decreases, the humidity increases, thus cooling the air. The cooled air can then be used to cool glyoxal liquid in the pipeline.

[0072] In this embodiment, two sets of cooling components 34 are provided, which are respectively located on both sides of the bottom inner wall of the outdoor housing 31.

[0073] In this embodiment, pumps are installed on both the first pipeline 4 and the sixth pipeline 9;

[0074] When in use, this application offers three usage modes based on the season;

[0075] 1. The natural cooling process in winter:

[0076] The compressor 23 of the refrigeration system does not work, and the cooling demand of the computer room is met directly by the external cold source: at this time, the first control valve 10 and the second control valve 11 are open, and the indoor supply fan 13 and the outdoor exhaust fan 33 are running; the third control valve 12 and the fourth control valve 13 are closed, and the glyoxal liquid in the pipeline is cooled in the outdoor heat exchanger 32 and then directly sent by the pump to the indoor heat exchange coil 12 to absorb the heat in the computer room and return to the outside; the entire cooling process only consumes electricity for the supply and exhaust fans 33 and the pump, and the energy consumption is only about 15% of that of traditional air conditioning.

[0077] 2. The transitional season's natural cooling + evaporative cooling process:

[0078] The compressor 23 of the refrigeration system does not work, and the cooling demand of the computer room is met directly by the external cold source. At this time, the first control valve 10 and the second control valve 11 are opened, and the indoor supply fan 13, the outdoor exhaust fan 33 and the cooling component 34 are running. The third control valve 12 and the fourth control valve 13 are closed. After the outdoor air is cooled by the cooling component 34, it enters the heat exchanger 32 to exchange heat with the glyoxal liquid in the pipeline. After the ethylene glycol liquid is cooled to the required temperature, it is directly sent by the pump to the heat exchange coil 12 in the indoor part, absorbs the heat in the computer room and returns to the outside. The entire cooling process only consumes electricity for the supply and exhaust fan 33, the pump and the cooling component 34, and the energy consumption is only about 15% of that of traditional air conditioning.

[0079] 3. Summer evaporative cooling + water cooling process

[0080] The compressor 23 of the refrigeration system is working normally. At this time, the first control valve 10 and the second control valve 11 are closed, and the third control valve 12 and the fourth control valve 13 are open. The indoor air supply fan 13, the outdoor exhaust fan 33, and the cooling component 34 are running. After being cooled by the cooling component 34, the outdoor air enters the heat exchanger 32 to exchange heat with the glyoxal liquid in the pipeline. After the ethylene glycol liquid is cooled to the required temperature, it is directly sent by the pump to the condenser 22 in the indoor section, where it absorbs the heat of the refrigeration system and returns to the outside. The ethylene glycol in the refrigeration section enters the evaporator 24 through the pump for cooling and is then sent to the heat exchange coil 12 to cool the room. After adding the evaporative cooling device, the efficiency of the entire refrigeration system can be increased by more than 10%.

[0081] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
