Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, and in particular to a water tank assembly and a liquid-cooled energy storage air-conditioner. Background Art

[0002] At present, liquid-cooled air conditioners are developing rapidly. Compared with traditional air-cooled air conditioners, liquid-cooled air conditioners have the characteristics of significant energy-saving effects, lower working noise, strong constant temperature, and environmental friendliness, and are gradually being promoted and used.

[0003] In the prior art, the water tanks of liquid cooling systems in liquid-cooled air conditioners are generally configured in two types: open and closed. Open water tanks circulate water directly with the atmosphere, improving system exhaust and reducing system pressure. However, they also present issues such as high system resistance and internal pipe corrosion, and are difficult to repair and maintain. Closed water tanks circulate water within a sealed system, shielded from the outside atmosphere. This allows the system's internal pressure to be maintained within a relatively constant range, resulting in lower system resistance and less oxidation of the cooling system pipes. However, they present issues such as higher water system pressure and poor exhaust. Utility Model Content

[0004] The purpose of the utility model is to provide a water tank assembly and a liquid-cooled energy storage air conditioner with a simple structure, which can put the liquid cooling system in an open or semi-open state, and is simple and quick to fill with liquid. It can also avoid the low pressure of the system caused by the volatilization of the liquid in the tank, and maintain the system pressure within a relatively stable range.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A water tank assembly includes a tank filling pipe, a liquid discharge pipe, a central control pipe, a first switch valve, a second switch valve, a breathing valve and a first ball valve; wherein,

[0007] The box is connected to the liquid cooling system;

[0008] The filling pipe and the central control pipe are both located at the top of the box body, the drain pipe is located at the bottom of the box body, the first switch valve is arranged on the filling pipe, the second switch valve is arranged on the drain pipe, and the breathing valve and the first ball valve are both arranged on the central control pipe.

[0009] Optionally, a liquid level sensor is further included, which is arranged on the box body and is used to detect the liquid level height in the box body.

[0010] Optionally, the box body is provided with a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe is connected to the liquid outlet end of the liquid cooling system, and the liquid outlet pipe is connected to the liquid inlet end of the liquid cooling system.

[0011] Optionally, it further includes a pressure relief pipe and a pressure relief valve, wherein the pressure relief pipe is connected to the box body, and the pressure relief valve is arranged on the pressure relief pipe, and the pressure relief pressure of the pressure relief valve is greater than the high-pressure opening pressure of the breathing valve.

[0012] Optionally, the pressure relief opening pressure of the pressure relief valve is 2.5-3.5 bar.

[0013] Optionally, the high-pressure opening pressure of the breathing valve includes 0.8-1.4 bar.

[0014] Optionally, a second ball valve is further included, and the second ball valve is arranged on the pressure relief pipe.

[0015] Optionally, an alarm mechanism is further included, which is used to alarm when the liquid level in the box is higher than a first preset liquid level or lower than a second preset liquid level.

[0016] A liquid-cooled energy storage air conditioner comprises a liquid cooling system and any one of the above-mentioned water tank assemblies, wherein the liquid cooling system and the water tank assembly are connected.

[0017] Optionally, it further includes a liquid inlet circulation pipe and a liquid outlet circulation pipe, wherein the liquid inlet circulation pipe is connected to the liquid outlet pipe of the water tank assembly, and the liquid outlet circulation pipe is connected to the liquid inlet pipe of the water tank assembly.

[0018] Beneficial effects:

[0019] The water tank assembly provided by the present invention has two states: fully open and semi-open. Specifically, when operating in the fully open state, the first ball valve is closed to close the central control pipe, the first on-off valve is opened to open the liquid filling pipe, and the second on-off valve is closed to close the liquid discharge pipe. At this time, the interior of the tank is directly connected to the outside atmosphere through the liquid filling pipe, forming a fully open system. The advantages of this state are: when the internal pressure of the liquid cooling system is less than or equal to atmospheric pressure, liquid can be easily added to the liquid cooling system. When liquid needs to be discharged, the second on-off valve is opened to open the liquid discharge pipe, allowing the liquid in the tank to be easily discharged, making operation convenient. When working in a half-open state, close the first switch valve and the second switch valve to close the filling pipe and the discharge pipe, open the first ball valve to open the central control pipe, and the breathing valve will play a role at this time, making the box body a closed water tank. At this time, the breathing valve can only be opened when the pressure inside the box is too high or too low, corresponding to the high-pressure opening pressure or low-pressure opening pressure of the breathing valve. When the pressure inside the box is maintained between the high-pressure opening pressure or the low-pressure opening pressure of the breathing valve, the breathing valve is closed, thereby enabling the pressure of the liquid cooling system to be maintained in a relatively reasonable and stable pressure range.

[0020] The water tank assembly can effectively solve the problems of difficult filling and maintenance of the closed expansion tank liquid system, and can also avoid the natural volatilization of the open water tank liquid and the resulting low pressure of the system, maintaining the entire system within a relatively stable pressure range. It has a simple structure and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] This embodiment provides a water tank assembly. Figures 1 to 2 As shown, the water tank assembly includes a tank body 1, a liquid filling pipe 21, a liquid discharge pipe 22, a central control pipe 23, a first on-off valve 31, a second on-off valve 32, a breathing valve 33, and a ball valve 34. The tank body 1 is connected to the liquid cooling system 5. The liquid filling pipe 21 and the central control pipe 23 are both located at the top of the tank body 1, and the liquid discharge pipe 22 is located at the bottom of the tank body 1. The first on-off valve 31 is provided on the liquid filling pipe 21, the second on-off valve 32 is provided on the liquid discharge pipe 22, and the breathing valve 33 and the first ball valve 34 are both provided on the central control pipe 23.

[0034] The water tank assembly has two states: fully open and semi-open. Specifically, when operating in the fully open state, the first ball valve 34 is closed to close the central control pipe 23, the first switch valve 31 is opened to open the liquid filling pipe 21, and the second switch valve 32 is closed to close the liquid discharge pipe 22. At this time, the interior of the tank body 1 is directly connected to the outside atmosphere through the liquid filling pipe 21, forming a fully open system. The advantages of this state are: when the internal pressure of the liquid cooling system 5 is less than or equal to atmospheric pressure, liquid can be easily added to the liquid cooling system 5. When liquid needs to be discharged, the second switch valve 32 is opened to open the liquid discharge pipe 22, and the liquid in the tank body 1 can be easily discharged, which is convenient to operate. When working in a semi-open state, the first switch valve 31 and the second switch valve 32 are closed to close the filling pipe 21 and the discharge pipe 22, and the first ball valve 34 is opened to open the central control pipe 23. At this time, the breathing valve 33 plays a role, making the box body 1 a closed water tank. At this time, the breathing valve 33 can only be opened when the internal pressure of the box body 1 is too high or too low, corresponding to the high-pressure opening pressure or low-pressure opening pressure of the breathing valve 33. When the pressure in the box body 1 is maintained between the high-pressure opening pressure or the low-pressure opening pressure of the breathing valve 33, the breathing valve 33 is closed, thereby enabling the pressure of the liquid cooling system 5 to be maintained in a relatively reasonable and stable pressure range.

[0035] The water tank assembly can effectively solve the problems of difficult filling and maintenance of the closed expansion tank liquid system, and can also avoid the natural volatilization of the open water tank liquid and the resulting low pressure of the system, maintaining the entire system within a relatively stable pressure range. It has a simple structure and strong practicality.

[0036] In addition, the water tank assembly operates in a semi-open state, reducing the contact of external air with the tank and system pipes, and can also effectively reduce oxidation and rust of the tank and internal pipes.

[0037] Specifically, the water tank assembly can manually select its operating mode during actual use. When adding or draining liquid from the liquid cooling system 5 for maintenance, the fully open operating mode is selected, facilitating maintenance and improving efficiency. The semi-open operating mode, on the other hand, is primarily used to maintain stable pressure in the liquid cooling system 5 during normal operation. This manual operating mode selection effectively mitigates the shortcomings of both open and closed systems, enhancing adaptability and improving efficiency.

[0038] Specifically, the filling pipe 21 is located at the top of the tank 1, facilitating manual filling of the tank 1 by the operator, while also maximizing internal space utilization and raising the effective liquid level. The drain pipe 22 is located at the bottom of the tank 1, ensuring that the liquid within the tank is drained as completely as possible under its own gravity. For example, the central control pipe 23 is located at the top of the tank 1. This arrangement fully utilizes the upper space of the tank 1, facilitates piping layout and maintenance operations, and effectively discharges rising gas within the tank.

[0039] In this embodiment, the first ball valve 34 is located on a side closer to the housing 1 .

[0040] In this embodiment, the water tank assembly further includes a liquid level sensor 4, which is disposed on the tank body 1 and is used to detect the liquid level within the tank body 1. By providing the liquid level sensor 4, the liquid level within the tank body 1 is promptly detected, enabling timely replenishment or drainage of the tank body 1. This prevents the breathing valve 33 from being blocked and rendered inoperative due to an excessively high liquid level within the tank body 1, or from being depleted due to an excessively low liquid level within the tank body 1.

[0041] Optionally, the liquid level sensor 4 includes a float type liquid level sensor, a pressure type liquid level sensor, an ultrasonic liquid level sensor, a capillary liquid level sensor, etc., all of which are existing technologies and are not limited here.

[0042] In this embodiment, the housing 1 is provided with a liquid inlet pipe 11 and a liquid outlet pipe 12. The liquid inlet pipe is connected to the liquid outlet of the liquid cooling system, and the liquid outlet pipe 12 is connected to the liquid inlet of the liquid cooling system. The coolant in the liquid cooling system is discharged through the liquid outlet and enters the housing 1 through the liquid inlet pipe 11. The coolant in the housing 1 is then discharged through the liquid outlet pipe 12 and returned to the liquid cooling system through the liquid inlet of the liquid cooling system.

[0043] Exemplarily, the high-pressure opening pressure of the breathing valve 33 is within a range of 0.8-1.4 bar, and the low-pressure opening pressure of the breathing valve 33 is within a range of 0.1-0.5 bar. In this embodiment, the high-pressure opening pressure of the breathing valve 33 is set to 1.2 bar, and the low-pressure opening pressure of the breathing valve 33 is set to 0.3 bar. When the pressure within the tank 1 is between 0.3 and 1.2 bar, the breathing valve 33 does not open. When the pressure within the tank is less than 0.3 bar or greater than 1.2 bar, the breathing valve 33 opens.

[0044] In this embodiment, the water tank assembly also includes a pressure relief pipe 24 and a pressure relief valve 35. The pressure relief pipe 24 is connected to the tank body 1. The pressure relief valve 35 is installed on the pressure relief pipe 24. The pressure relief opening pressure of the pressure relief valve 35 is greater than the high-pressure opening pressure of the breathing valve 33. Specifically, the pressure relief pipe 24 and the pressure relief valve 35 are used to prevent the breathing valve 33 and other pipelines from clogging due to excessive pressure in the tank body 1 and causing it to burst, thereby providing effective pressure relief and safety protection.

[0045] Exemplarily, the pressure relief opening pressure of the pressure relief valve 35 is within a range of 2.5-3.5 bar. In this embodiment, the pressure relief opening pressure of the pressure relief valve 35 is set to 3 bar. If the pressure in the box 1 continues to rise to 3 bar due to reasons such as blockage of the breathing valve 33 or other pipelines, the pressure relief valve 35 automatically opens, providing timely and effective pressure relief to the box 1.

[0046] Exemplarily, the pressure relief pipe 24 is located at the top of the box body 1. This arrangement makes full use of the upper space of the box body 1, facilitates pipeline layout and maintenance operations, and is beneficial to the effective discharge of rising gas in the box.

[0047] As an optional embodiment, a pressure gauge (not shown) is further provided on the box body 1. The pressure gauge is used to detect and display the pressure inside the box in real time, so that the operator can quickly and easily obtain the pressure data inside the box. Optionally, the pressure gauge is located at the top of the box body 1, which is arranged so as to facilitate observation.

[0048] In this embodiment, the water tank assembly also includes a second ball valve 36 , which is disposed on the pressure relief pipe 24 . Specifically, the second ball valve 36 is configured to open and close the pressure relief pipe 24 . Specifically, when in the fully open position, the second ball valve 36 closes, thereby closing the pressure relief pipe 24 ; when in the half-open position, the second ball valve 36 opens, thereby opening the pressure relief pipe 24 .

[0049] As an optional embodiment, the water tank assembly further includes an alarm mechanism (not shown) configured to sound an alarm when the liquid level in the tank body 1 is above a first preset level or below a second preset level. Specifically, the liquid level sensor 4 is communicatively connected to the alarm mechanism via a control module such as a PLC. When the liquid level sensor 4 detects that the liquid level in the tank body 1 is above the first preset level or below the second preset level, the control module sends a signal to the alarm mechanism, causing the alarm mechanism to sound an alarm, thereby promptly alerting the operator to refill or drain the tank body 1.

[0050] Optionally, the alarm mechanism is configured as a buzzer and / or an alarm light. When the alarm mechanism sounds an alarm, the buzzer sounds and the alarm light flashes, enabling the user to perceive the alarm information from the visual and auditory sensory dimensions, further enhancing the reliability and effectiveness of the alarm mechanism's action.

[0051] Optionally, a sealing ring (not shown) is further provided between the box body 1 and the filling pipe 21, the discharge pipe 22, the central control pipe 23, the pressure relief pipe 24, the liquid inlet pipe 11, and the liquid outlet pipe 12 to seal the gaps at the connection parts of the box body 1 and the filling pipe 21, the discharge pipe 22, the central control pipe 23, the pressure relief pipe 24, the liquid inlet pipe 11, and the liquid outlet pipe 12, so as to further ensure the sealing of the box body 1 itself.

[0052] Reference Figure 2 This embodiment also provides a liquid-cooled energy storage air conditioner, which includes a liquid cooling system 5 and the above-mentioned water tank assembly, and the liquid cooling system 5 and the water tank assembly are connected. Specifically, the liquid cooling system 5 is connected to the box body 1. Furthermore, the liquid-cooled energy storage air conditioner also includes a liquid inlet circulation pipe 51 and a liquid outlet circulation pipe 52.

[0053] The inlet circulation pipe 51 is connected to the water tank assembly's outlet pipe 12, and the outlet circulation pipe 52 is connected to the water tank assembly's inlet pipe 11. The coolant in the liquid cooling system 5 can flow into the housing 1 through the outlet circulation pipe 52 and the inlet pipe 11. The coolant in the housing 1 can also flow back to the liquid cooling system 5 through the outlet pipe 12 and the inlet circulation pipe 51, thus achieving a circulating flow of the coolant.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
