Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning liquid cooling systems, specifically to an air venting structure for an air conditioning liquid cooling system. Background Technology

[0002] In air conditioning liquid cooling systems, a water pump is typically installed in the liquid cooling system piping to provide the power for liquid circulation. However, for open-tank liquid cooling systems, the following problem arises when adding water to the open tank: when the liquid cooling system is connected and water is added to the open tank, a large amount of air cannot be expelled from the liquid cooling system piping. If the water pump is not a self-priming pump, the liquid drawn into the pump will contain a large amount of air, causing the pump to malfunction. In this situation, the user usually needs to manually bleed the system, that is, manually adding water to the liquid cooling system while simultaneously draining water from it. This continuous adding and draining of water is not only inefficient and wasteful of water resources, but if not bleeded in time, it can lead to obstructed water flow, abnormal pressure, or even equipment damage. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a venting structure for an air conditioning liquid cooling system, which can automatically vent, ensure the normal operation of the water pump, and save water resources.

[0004] This utility model adopts the following technical solution: a venting structure for an air conditioning liquid cooling system, comprising a first water tank, a circulating water pump, and a heat exchanger connected in sequence. The first water tank is an open structure. A venting pipe is connected in parallel on the connecting pipe between the first water tank and the circulating water pump. A first water pump, a second water tank, and a second water pump are connected in sequence in the venting pipe. The inlet of the first water pump is connected to the outlet of the first water tank, and the outlet of the second water pump is connected to the inlet of the circulating water pump. The second water tank is a closed structure, and an exhaust port is provided at the top of the second water tank.

[0005] Furthermore, the second water tank is provided with an inlet and an outlet, the inlet being located at the upper part of the second water tank and the outlet being located at the lower part of the second water tank, and a liquid level switch is provided inside the second water tank; Furthermore, both the first and second water pumps are connected to a timer; Furthermore, a flow regulating valve is connected to the outlet end of the second water pump, and a temperature sensor is installed on the connecting pipeline between the first water tank and the heat exchanger. Furthermore, a first pressure sensor is provided on the connecting pipe between the circulating water pump and the heat exchanger, and a second pressure sensor is provided on the connecting pipe between the heat exchanger and the first water tank; Furthermore, the venting structure also includes a controller, and the level switch, timer, circulating water pump, flow regulating valve, temperature sensor, first water pump, second water pump, first pressure sensor, and second pressure sensor are all connected to the controller, which is a TA108DB2 controller.

[0006] The beneficial effects of this utility model are that, by connecting a drain pipe in parallel to the outlet pipe of the first water tank, after a certain amount of water is injected into the first water tank, a small amount of water containing air can be drawn into the second water tank by the first water pump. The air in the water in the second water tank is then discharged from the vent. At the same time, the second water pump can pump the emptied water in the second water tank into the circulating water pump. With continuous emptying, the air in the main circulating water circuit is continuously removed, thus ensuring that there is no air at the inlet of the circulating water pump. This ensures the normal operation of the circulating water pump, and eliminates the need for manual water addition and drainage, improving the emptying efficiency and saving water resources, thus having good economic value.

[0008] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention discloses a venting structure for an air conditioning liquid cooling system, comprising a first water tank 1, a circulating water pump 2, and a heat exchanger 3 connected in sequence. The first water tank 1 is an open structure. A venting pipe is connected in parallel on the connecting pipe between the first water tank 1 and the circulating water pump 2. A first water pump 4, a second water tank 5, and a second water pump 6 are connected in sequence in the venting pipe. The inlet of the first water pump 4 is connected to the outlet of the first water tank 1, and the outlet of the second water pump 6 is connected to the inlet of the circulating water pump 2. The second water tank 5 is a closed structure, and an exhaust port 7 is provided at the top of the second water tank 5. When water containing air enters the second water tank 5, the air will be automatically discharged through the exhaust port 7.

[0009] The second water tank 5 is equipped with an inlet 8 and an outlet 9. The inlet 8 is located at the top of the second water tank 5, and the outlet 9 is located at the bottom of the second water tank 5. The second water tank 5 is equipped with a level switch 10, which is used to turn on and off the first water pump 4 and the second water pump 6 to prevent the water inside the second water tank 5 from overflowing due to excessive water level. That is, after the level switch 10 detects the water level, it sends the water level information to the controller in real time. Once the water level is exceeded, the controller will shut down the first water pump 4 and turn on the second water pump 6 until the alarm of the level switch 10 disappears, and then continue to drain the water.

[0010] Both the first water pump 4 and the second water pump 6 are connected to the timer 11. The shutdown of the first water pump 4 and the second water pump 6 can be determined by the timer 11 to determine the running time of the first water pump 4 and the second water pump 6.

[0011] The outlet of the second water pump 6 is connected to a flow regulating valve 12. A temperature sensor 13 is installed on the connecting pipe between the first water tank 1 and the heat exchanger 3. The temperature sensor 13 detects the temperature of the water discharged from the heat exchanger 3 in real time and sends the temperature signal to the controller, which can control the opening degree of the flow regulating valve 12 accordingly to control the output of the second water pump 6.

[0012] A first pressure sensor 14 is installed on the connecting pipe between the circulating water pump 2 and the heat exchanger 3, and a second pressure sensor 15 is installed on the connecting pipe between the heat exchanger 3 and the first water tank 1. The first pressure sensor 14 and the second pressure sensor 15 can respectively detect the water pressure flowing into the heat exchanger 3 and the water pressure flowing out and into the first water tank 1. When the water pressure detected by the first pressure sensor 14 and the second pressure sensor 15 is greater than the set pressure, the circulating water pump 2 can be shut down by the controller or the flow regulating valve 12 can be adjusted accordingly to maintain the heat exchange stability in the heat exchanger 3 and the water inlet stability of the first water tank 1.

[0013] The venting structure also includes a controller, a level switch 10, a timer 11, a circulating water pump 2, a flow regulating valve 12, a temperature sensor 13, a first water pump 4, a second water pump 6, a first pressure sensor 14, and a second pressure sensor 15, all of which are connected to the controller. The controller is a TA108DB2 controller.

[0014] Generally, when the cooling capacity of an air conditioning liquid cooling system is relatively small, the circulating water pump 2 required by the air conditioning liquid cooling system is relatively small. Generally, the circulating water pump 2 can only be a conventional electronic pump. Such pumps cannot achieve self-priming water capability. The circulating water pump 2 can be a conventional electronic pump, and pumps without self-priming function can be used. The outlet of the circulating water pump 2 is connected to the heat exchanger 3. After heat exchange, the water flows into the open first water tank 1. The open first water tank 1, the circulating water pump 2 and the heat exchanger 3 form the main circulating water circuit. The drain pipe is composed of the first water pump 4, the second water tank 5, the second water pump 6, the timer 11 and the liquid level switch 10 in the second water tank 5.

[0015] In this invention, a main circulating water circuit is formed by sequentially connecting a first water tank 1, a circulating water pump 2, and a heat exchanger 3. The heat exchanger 3 is mainly used to cool the main circulating water circuit, and the circulating water pump 2 is mainly used to provide circulating power. A drain pipe is installed in parallel at the outlet of the first water tank 1, and a first water pump 4, a second water tank 5, and a second water pump 6 are sequentially connected in the drain pipe. The first water pump 4 continuously draws water from the open first water tank 1 and discharges it into the second water tank 5, while the second water pump 6 discharges water from the second water tank 5. It is also continuously discharged back into the main circulating water circuit. That is, when the first water pump 4 pumps the water in the main circulating water circuit into the second water tank 5, the air in the water in the second water tank 5 is expelled. The second water pump 6 then sucks the water in the second water tank 5 and discharges it into the main circulating water circuit, thereby expelling the air in the main circulating water circuit and realizing automatic emptying. This ensures that the circulating water pump 2 can operate normally. During the emptying process, the water in the main circulating water circuit can be continuously circulated through the second water tank 5 without needing to be discharged, thus saving a lot of water resources.
