Description
Technical Field
[0001] The utility model belongs to the technical field of air conditioning and refrigeration, and in particular relates to an integrated fluorine pump water-fluorine unit for heat dissipation in a data center. Background Art
[0002] As global temperatures rise year by year, global extreme temperatures continue to increase. Natural disasters caused by temperature changes are increasingly frequent in different regions. And breaking records again and again, low carbon, carbon reduction, and carbon neutrality have become the only way to solve the above climate problems. Energy conservation and carbon reduction in various fields have become the focus of attention. Data centers, as energy-intensive consumers, are no exception, and the equipment with the largest energy consumption in data centers is the air conditioning system. Therefore, energy conservation and carbon reduction of air conditioning systems have become a top priority in this field. Most data centers in my country are mainly compressor refrigeration and air conditioning. Therefore, solving problems such as high energy consumption of air-cooled compressor refrigeration and air conditioning outdoor units will help improve a series of problems caused by compressor refrigeration and air conditioning due to high temperatures in summer. It also contributes to the goal of energy conservation and carbon reduction. The traditional solutions currently in use are: direct spraying or water spraying cooling on the cooler fins and humidifying membrane water spraying cooling device on the air inlet side of the condenser; due to the high temperature of the condenser fins, the direct spraying or water spraying cooling scheme on the cooler fins causes the condenser fins to corrode quickly, scale seriously, and heat exchange attenuation is obvious. Although the high temperature problem is solved in a short time, it causes serious subsequent problems and even causes the air conditioning unit to be scrapped. Although the humidifying film water spraying and cooling device on the air inlet side of the condenser can change the condenser inlet temperature, it increases the condenser inlet resistance, which seriously affects the condenser inlet volume. As the degree of dirt and blockage on the wet film surface increases, the condenser inlet resistance becomes larger and larger, affecting the air inlet volume and the heat exchange capacity of the condenser.

DETAILED DESCRIPTION
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.
[0020] Example 1
[0021] exist Figures 1 to 5 In the utility model, the integrated fluorine pump water fluorine unit for heat dissipation in a data center is provided with a water tank 15 at the bottom of the chassis 7, which is connected to an external water tank. The water tank 15 provides circulating cooling water for the device. Specifically, a water replenishment float 1 is provided on the lower side wall of the chassis 7, one end of the water replenishment float 1 is located in the water tank 15, and the other end is connected to the external water tank. When the water level in the water tank 15 drops, the water replenishment float 1 drops, so that the cooling water in the external water tank enters the water tank 15. When the water level in the water tank 15 rises to a specified position, the water replenishment float 1 rises to close the water inlet end, preventing the water in the external water tank from entering the water tank 15. A heat dissipation device 12 is provided on the upper part of the water tank 15 inside the chassis 7. The heat dissipation device 12 is composed of several layers of heat sinks arranged at equal intervals. The convex hulls and grooves arranged regularly on the heat sinks are used for heat exchange between air and water. The interlayer spacing of the heat sink 12-1 is 12 to 25 mm. A second filter 13 is provided on the right side of the heat sink 12, and an electric air valve 14 is provided on the outer side of the chassis 7 corresponding to the second filter 13. The electric air valve 14 is closed in winter to prevent air flow short-circuiting when the heat sink 12 is not watered in winter. When there is no watering, the outdoor air passes through the first filter 9 and enters the unit for heat exchange. In summer, the electric air valve 14 is opened, and a part of the air flow passes through the second filter 13 and enters the unit through the electric air valve 14 to cool the heat sink 12 by watering.
[0022] A water-fluorine heat exchange device 11 is arranged on the upper part of the heat dissipation device 12, a first filter 9 is arranged on the top of the chassis 7 corresponding to the water-fluorine heat exchange device 11, and an exhaust fan 8 is arranged on the upper left part of the chassis 7 in communication with the chassis 7. Specifically, the water-fluorine heat exchange device 11 is composed of a shell 11-1, a coil 11-2, an inlet pipe 11-3, and an outlet pipe 11-4. A plurality of groups of coils 11-2 are arranged in the rectangular shell 11-1 with upper and lower openings. The coils 11-2 are S-shaped structures, one end of the coils 11-2 is connected to the inlet pipe 11-3, and the other end is connected to the outlet pipe 11-4. After entering, the high-temperature gas flows in the plurality of groups of coils 11-2. The diameter of the coil 11-2 is 16 to 25 mm. Furthermore, the upper end of the shell 11-1 of the water-fluorine heat exchange device 11 is connected to the inner wall of the chassis 7, and the lower end is connected to the upper end of the heat dissipation device 12. A spray device 10 is provided at the upper part of the water-fluorine heat exchange device 11. The spray device 10 is connected to the water tank 15 through a spray circulation pump 16 installed on the pipeline. The spray device 10 is located inside the shell 11-1 to ensure that the water sprayed by the spray device 10 passes through the coil 11-2. The cooling water cools the high-temperature gas in the coil 11-2 for heat exchange. The water after heat exchange enters the heat sink 12 for cooling and heat exchange and then flows back into the water tank 15 for recycling. The shell 11-1 forms a relatively sealed space, so that the air entering the first filter 9 flows downward, and after further cooling the high-temperature gas in the coil 11-2, the air enters the heat sink 12 and is discharged from the chassis 7 through the exhaust fan 8.
[0023] The inlet of the water-fluorine heat exchange device 11 is connected to the high-temperature gas pipe 3 through the first electric valve 4 installed on the pipeline, and is connected to the high-temperature gas pipe 3 through the fluorine pump 6 and the second electric valve 5 installed on the pipeline. The fluorine pump 5 is arranged on the inner wall of the chassis 7 below the lower end of the exhaust fan 8. The high-temperature gas pipe 3 is connected to the outlet of the indoor unit of the air conditioner, and the outlet of the water-fluorine heat exchange device 11 is connected to the inlet of the indoor unit of the air conditioner through the low-temperature liquid pipe 2.
[0024] The principle of the utility model is as follows:
[0025] In summer, when the compressor is working, the high-temperature refrigerant from the compressor goes through the bypass pipeline on the side of the fluorine pump 6 and directly enters the water-fluorine heat exchange device 11 for cooling. That is, in summer, the first electric valve 4 is opened, the second electric valve 5 is closed, and the spray circulation pump 16 transports the circulating cooling water in the water tank 15 to the spray device 10 to perform evaporative cooling on the water-fluorine heat exchange device 11. The airflow is divided into two parts. One part of the airflow enters the water-fluorine heat exchange device 11 from the first filter 9, passes through the heat sink 12, and is then discharged to the outside of the unit by the exhaust fan 8. The other part of the airflow passes through the electric air valve 4 through the second filter 13 and enters the heat sink 12, and is then discharged to the outside of the unit by the exhaust fan 8.
[0026] In winter, the compressor in the indoor unit of the air conditioner stops working, the fluorine pump 6 works, the first electric valve 4 is closed, and the second electric valve 5 is opened. The fluorine pump 5 drives the Freon to exchange heat in the indoor unit and the outdoor unit of the air conditioner (integrated fluorine pump water-fluorine unit). The spray circulation pump 16 does not work, the electric air valve 14 is closed, and the outdoor cold air enters the unit through the first filter 9, passes through the water-fluorine heat exchange device 11 for cooling, and is then discharged to the outside of the unit through the heat dissipation device 12 by the exhaust fan 8.
