Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation in data centers, and in particular to a heat dissipation system applied to data centers. Background Art

[0002] As technology advances into the rapidly developing information age, the huge amount of data and information generated by the communication equipment we use every day needs to be processed by servers. In order to facilitate the management and maintenance of the server, it is usually necessary to build an independent data center.

[0003] In data centers, fans are usually installed directly on each computer module to perform direct air blowing to dissipate heat and cool down the computer. However, this cooling method has a relatively poor cooling effect, so further improvements can be made. Summary of the invention

[0004] In order to improve the cooling effect on computer modules in a data center, the present application provides a heat dissipation system applied to a data center.

[0005] The present application provides a heat dissipation system for a data center using the following technical solutions:

[0006] A heat dissipation system used in a data center includes a circulating water circuit, a fin-tube heat exchanger and a heat dissipation fan; the fin-tube heat exchanger and the heat dissipation fan are both arranged and installed outside the data center, the circulating water circuit is used to perform water-cooling heat exchange on computer modules, and performs air-cooling heat exchange with external air by cooperating with the fin-tube heat exchanger and the heat dissipation fan.

[0007] By adopting the above technical solution, the circulating water circuit and the computer module are used for water cooling heat exchange to achieve cooling. At the same time, the circulating water circuit brings the heat to the fin tube heat exchanger, and the heat dissipation fan is used for air cooling to achieve the entire circulating water cooling. This water cooling method can bring the heat to the outside of the data center through the water circuit, and then use the fin tube heat exchanger and the heat dissipation fan to exchange heat and cool down, and its cooling effect is relatively good.

[0008] Optionally, the circulating water circuit includes an inlet pipe, an outlet pipe, a water distributor, a water collector, a circulating water pump and a steam-water separator; the water cooling water inlet in the computer module is connected to the inlet pipe through the water distributor, the water cooling water outlet in the computer module is connected to the outlet pipe through the water collector, and the end of the inlet pipe away from the water distributor is connected to the outlet end of the fin-tube heat exchanger, and the end of the outlet pipe away from the water collector is connected to the inlet end of the fin-tube heat exchanger; the steam-water separator is installed on the outlet pipe, and the circulating water pump is used to control the circulation flow of the entire water circuit.

[0009] By adopting the above technical scheme, under the control of the circulating water pump, the water inlet pipe passes through the water distributor and flows into the water cooling inlet in the computer module for water cooling heat exchange. The water after heat exchange converges to the water outlet pipe through the water collector, and after being processed by the steam-water separator, it flows into the fin tube heat exchanger for air cooling. The cooled water flows back to the water inlet pipe to form a circulating heat dissipation water circuit to continuously cool the computer module with water.

[0010] Optionally, the steam-water separator includes a tank body, the water inlet of the tank body is arranged at the top, and the water outlet of the tank body is arranged at the bottom; a plurality of bubble baffles are provided in the tank body, and the bubble baffles are arranged alternately from top to bottom; and an exhaust port is provided at the top of the tank body.

[0011] By adopting the above technical solution, the water after heat exchange with the computer module enters the tank from the water inlet at the top of the tank, and then separates the water vapor through the bubble baffle, so that the vapor is blocked and retained at the top of the tank, while the water flows out through the water outlet at the bottom of the tank for subsequent heat exchange treatment. At the same time, the vapor retained in the tank can be controlled and discharged through the exhaust port at the top.

[0012] Optionally, a liquid replenishing port is also provided on the top of the tank body.

[0013] By adopting the above technical solution, as the use time increases, part of the water inside the tank is lost by vaporization. At this time, it can be replenished through the liquid replenishing port.

[0014] Optionally, an airbag is installed at the top of the tank body, and the inflation nozzle of the airbag passes through the tank body.

[0015] By adopting the above technical solution and installing an airbag in the tank, in the actual practical process, when pressure fluctuations occur inside the tank due to pumping or other reasons, the airbag can use its own internal gas characteristics to perform buffering and stabilization. When the pressure inside the tank increases, the airbag is automatically compressed, so that the remaining space of the tank increases, and the pressure inside the tank is relieved; when the pressure inside the tank decreases, the airbag automatically expands, so that the remaining space of the tank decreases, and the pressure inside the tank is relieved, so as to further ensure the stability of the pressure inside the tank.

[0016] Optionally, an electric heater is also provided in the tank body.

[0017] By adopting the above technical solution, the electric heater does not work in the normal water cooling working mode. When the external environment temperature is too low, the normal operation of the computer module is affected by the low temperature. At this time, the electric heater can be turned on to heat the water in the tank, so that the computer can be heated by the circulating water circuit to ensure the normal operation of the computer module in a low temperature environment.

[0018] Optionally, an observation window is provided on the tank body.

[0019] By adopting the above technical solution, in actual use, the internal state of the tank can be monitored through the observation window, and corresponding countermeasures can be taken in time.

[0020] Optionally, shock absorbing pipes are installed on both sides of the water outlet pipe of the circulation pump.

[0021] By adopting the above technical solution, in actual practical application, the vibration on the water outlet pipe can be damped through the shock-absorbing pipe to reduce the transmission of the vibration.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Under the control of the circulating water pump, the water inlet pipe flows into the water cooling water inlet of the computer module through the water distributor for water cooling heat exchange. The water after heat exchange flows into the water outlet pipe through the water collector. After being processed by the steam-water separator, it flows into the fin tube heat exchanger from the water inlet end of the fin tube heat exchanger to pass through the heat dissipation fan for air cooling heat exchange and cooling with the external air. The cooled water flows back to the water inlet pipe from the water outlet end of the fin tube heat exchanger to form a circulating heat dissipation water path to continuously cool the computer module. This water cooling method can bring heat to the outside of the data center through the water path, and then use the fin tube heat exchanger and the heat dissipation fan for heat exchange and cooling, and its cooling effect is relatively good;

[0024] 2. The bubble baffle, liquid filling port, air bag and electric heater in the tank of the steam-water separator are used to realize the integrated integration of liquid filling, constant pressure and heating while performing steam-water separation, which not only simplifies the complexity of the system, but also reduces energy consumption and improves the reliability and maintainability of the system. The integrated design means fewer connection points, reduces the potential failure rate, and optimizes the use of space, making the equipment more compact and efficient;

[0025] 3. In actual practical use, the vibration on the water outlet pipe can be damped by a shock-absorbing pipe to reduce the transmission of vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] An embodiment of the present application discloses a heat dissipation system for use in a data center.

[0032] Reference Figure 1 A heat dissipation system for use in a data center comprises a circulating water circuit 100, a fin-tube heat exchanger 200 and a heat dissipation fan 300; wherein the fin-tube heat exchanger 200 and the heat dissipation fan 300 are both arranged and installed outside the data center, and the circulating water circuit 100 comprises a water inlet pipe 1, a water outlet pipe 2, a water distributor 3, a water collector 4, a circulating water pump 5 and a steam-water separator 6; a water-cooled water inlet in a computer module 400 is connected to the water inlet pipe 1 through the water distributor 3, and a water-cooled water outlet in the computer module 400 is connected to the water outlet pipe 2 through the water collector 4, and an end of the water inlet pipe 1 away from the water distributor 3 is connected to the water outlet end of the fin-tube heat exchanger 200, and an end of the water outlet pipe 2 away from the water collector 4 is connected to the water inlet end of the fin-tube heat exchanger 200; the steam-water separator 6 and the circulating water pump 5 are both installed on the water outlet pipe 2, and the circulating water pump 5 is arranged at the output end of the steam-water separator 6, so as to control the circulation flow of the entire water circuit.

[0033] Under the control of the circulating water pump 5, the water inlet pipe 1 flows into the water cooling water inlet of the computer module 400 through the water distributor 3 for water cooling heat exchange. The water after heat exchange flows into the water outlet pipe 2 through the water collector 4. After being processed by the steam-water separator 6, it flows into the fin tube heat exchanger 200 from the water inlet end of the fin tube heat exchanger 200, and passes through the heat dissipation fan 300 to perform air cooling heat exchange and cooling with the external air. The cooled water flows back to the water inlet pipe 1 from the water outlet end of the fin tube heat exchanger 200 to form a circulating heat dissipation water path to continuously cool the computer module 400. This water cooling method can bring heat to the outside of the data center through the water path, and then use the fin tube heat exchanger 200 and the heat dissipation fan 300 for heat exchange and cooling, and its cooling effect is relatively good.

[0034] In this embodiment, the heat dissipation fan 300 adopts a high-cylinder fan to increase the dynamic pressure of the fan and the regional wind island effect. The dynamic pressure of the heat dissipation fan is higher, the fan range is longer, and the heat dissipation capacity is greater.

[0035] Reference Figure 1 In this embodiment, manual butterfly valves 7 are installed on both sides of the circulation pump for manual control of opening or closing. Two shock-absorbing pipes 8 are installed on the water outlet pipe 2, and the two shock-absorbing pipes 8 are respectively arranged on the side of the two manual butterfly valves 7 away from the circulation pump, for shock-absorbing the vibration on the water outlet pipe 2 to reduce the transmission of vibration. Similarly, a shock-absorbing pipe 8 is also installed on the water inlet pipe 1 to shock-absorbing the vibration on the water inlet pipe 1 to reduce the transmission of vibration.

[0036] Reference Figure 2 Specifically, in the present embodiment, the steam-water separator 6 includes a tank body 61, and the water inlet of the tank body 61 is arranged at the top, and the water outlet of the tank body 61 is arranged at the bottom. A plurality of bubble baffles 62 are arranged in the tank body 61, and the bubble baffles 62 are arranged alternately from top to bottom. An exhaust port 63 is provided at the top of the tank body 61, and the exhaust port 63 is controlled by an exhaust valve. During operation, water after heat exchange with the computer module 400 enters the tank body 61 from the water inlet at the top of the tank body 61, and then undergoes water vapor separation through the bubble baffle 62, so that the steam is blocked and retained at the top of the tank body 61, and the water flows out through the water outlet at the bottom of the tank body 61 for subsequent heat exchange treatment. At the same time, the steam retained in the tank body 61 can be controlled and discharged through the exhaust port 63 at the top.

[0037] Reference Figure 2 The tank body 61 is provided with an observation window 64, a liquid replenishment port 65 is provided at the top of the tank body 61, and a drainage port 66 is provided at the bottom of the tank body 61. In actual practical use, the internal state of the tank body 61 can be monitored through the observation window 64, and corresponding countermeasures can be taken in time. At the same time, as the use time increases, part of the water inside the tank body 61 is lost by vaporization. At this time, it can be replenished through the liquid replenishment port 65, and can be drained through the drainage port 66 at the bottom.

[0038] Reference Figure 2 , an airbag 67 is also installed at the top position of the tank body 61. In this embodiment, the airbag 67 is ring-shaped, and the inflation nozzle 69 of the airbag 67 passes through the tank body 61. In the actual practical process, when the pressure inside the tank body 61 fluctuates due to pumping and other reasons, the airbag 67 can use the gas characteristics inside it to perform buffering and stabilization. When the pressure inside the tank body 61 increases, the airbag 67 is automatically compressed to increase the remaining space of the tank body 61, and the pressure inside the tank body 61 is relieved; when the pressure inside the tank body 61 decreases, the airbag 67 automatically expands to reduce the remaining space of the tank body 61, and the pressure inside the tank body 61 is relieved, so as to further ensure the stability of the pressure inside the tank body 61.

[0039] Reference Figure 2In this embodiment, an electric heater 68 is further provided in the tank body 61. In the normal water cooling working mode, the electric heater 68 does not work. When the external environment temperature is too low, the normal operation of the computer module is affected by the low temperature. At this time, the electric heater 68 can be turned on to heat the water in the tank body 61, so that the circulating water circuit 100 can be used to heat the computer to ensure the normal operation of the computer module in a low temperature environment.

[0040] The system can realize the integration of liquid replenishment, constant pressure and heating while separating steam and water, which not only simplifies the complexity of the system, but also reduces energy consumption and improves the reliability and maintainability of the system. The integrated design means fewer connection points, reduces the potential failure rate, and optimizes the use of space, making the equipment more compact and efficient.

[0041] The working principle of a heat dissipation system applied to a data center in the present application is as follows: under the control of a circulating water pump 5, the water inlet pipe 1 flows in from the water cooling water inlet in the computer module 400 through the water distributor 3 to perform water cooling heat exchange. The water after heat exchange flows into the water outlet pipe 2 through the water collector 4, and after being processed by the steam-water separator 6, flows into the fin tube heat exchanger 200 from the water inlet end of the fin tube heat exchanger 200, and then passes through the heat dissipation fan 300 to perform air cooling heat exchange and cooling with the external air. The cooled water flows back to the water inlet pipe 1 from the water outlet end of the fin tube heat exchanger 200 to form a circulating heat dissipation water path to continuously cool the computer module 400. This water cooling method can bring heat to the outside of the data center through the water path, and then heat exchange and cooling are performed with the help of the fin tube heat exchanger 200 and the heat dissipation fan 300, and its cooling effect is relatively good.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
