[0004] To achieve the above objectives, the liquid replenishment tank proposed in this application includes a tank body, a liquid level tube, and a liquid level sensor. The liquid level tube is disposed on the outer wall of the tank body, and the upper end and the lower end of the liquid level tube are respectively connected to the inner cavity of the tank body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.
[0022] This application provides a replenishment tank to solve the problem of timely replenishment of the refrigerant in the replenishment tank. The following description will be provided in conjunction with the accompanying drawings.
[0023] In the embodiments of this application, such as Figure 1 As shown, the replenishment tank includes a tank body 1, a liquid level tube 2, and a liquid level sensor. The liquid level tube 2 is disposed on the outer wall of the tank body 1. The upper end and the lower end of the liquid level tube 2 are respectively connected to the inner cavity of the tank body 1. The liquid level sensor is located between the upper end and the lower end of the liquid level tube 2 and is connected to the inner cavity of the tank body 1.
[0024] It should be noted that the liquid level tube 2 refers to a tubular structure with a transparent portion. The liquid level tube 2 can be partially or completely transparent, allowing personnel to observe the liquid level inside the tank 1. The liquid level sensor can be a resistive liquid level switch.
[0025] Understandably, by placing the liquid level sensor between the upper end and the lower end of the liquid level tube 2, a signal is sent to indicate that refrigerant needs to be added when the height of the liquid level sensor cannot detect the liquid in the tank 1. At this time, the liquid level in the tank 1 is still a certain distance from the bottom of the tank 1, which can be replenished in time before the refrigerant is completely exhausted, thus avoiding the phenomenon of air being drawn out of the liquid replenishment tank and ensuring the pressure of the liquid cooling device is stable.
[0026] For example, the liquid level pipe 2 can be an arc-shaped bend, or it can be composed of a riser and two horizontal pipes connected to the upper and lower ends of the riser. The two horizontal pipes are perpendicular to the riser and are connected to the box body 1.
[0027] In some embodiments, such as Figure 1 As shown, the outer wall of the housing 1 is connected to a bypass connector 3. The bypass connector 3 is located between the upper end and the lower end of the liquid level pipe 2. The lower end of the bypass connector 3 is connected to the housing 1. The liquid level sensor is installed on the bypass connector 3 and is higher than the lower end of the bypass connector 3.
[0028] Understandably, using the bypass connector 3 to provide an installation position for the liquid level sensor is less likely to leave liquid residue at the installation connection point compared to directly inverting the liquid level sensor at the bottom of the housing 1, resulting in higher sensitivity. At the same time, since the liquid level sensor is higher than the lower end of the bypass connector 3, the installation connection point of the liquid level sensor can be set downwards, which helps to drain any residual liquid from the liquid level sensor, making it easier to observe and install it in place, reducing the risk of leakage caused by misalignment, and ensuring electrical safety.
[0029] In some embodiments, such as Figure 1 As shown, the vertical distance between the upper end of the bypass connector 3 and the upper end of the liquid level tube 2 is greater than the vertical distance between the lower end of the bypass connector 3 and the liquid level tube 2.
[0030] Understandably, by designing the bypass connector 3 to be positioned closer to the lower end of the liquid level pipe 2 than its upper end, the frequency of refrigerant replenishment can be reduced. The bypass connector 3 can be a bent pipe structure or a straight pipe structure. In some specific embodiments, the liquid level sensor is located at the upper end of the bypass connector 3.
[0031] In some embodiments, such as Figure 1 As shown, a liquid inlet 11 is provided on the side wall of the tank 1. The liquid inlet 11 is located higher than the bottom wall of the tank 1 and lower than the lower end of the liquid level pipe 2.
[0032] It is understandable that refrigerant is supplied to other devices through the refrigerant inlet 11. The refrigerant inlet 11 is located above the bottom wall of the tank 1. This height reduces the amount of impurities deposited on the bottom wall of the tank 1 that are discharged with the refrigerant, which helps ensure the normal operation and service life of other devices.
[0033] In some embodiments, such as Figure 2 As shown, the box body 1 is provided with a drain port 12, which is located below the liquid replenishment port 11; the drain port 12 is located on the bottom wall of the box body 1.
[0034] It is understandable that the impurities deposited inside the tank 1 are drained through the drain outlet 12. Setting the drain outlet 12 below the liquid replenishment port 11 and on the bottom wall of the tank 1 can drain the impurities as much as possible.
[0035] In some embodiments, such as Figure 2 As shown, the box body 1 is provided with a liquid inlet 13, and a liquid blocking part 14 is provided inside the box body 1. The liquid blocking part 14 is spaced apart from the liquid inlet 13 and blocks the liquid inlet 13.
[0036] It should be noted that the liquid-blocking part 14 blocking the liquid inlet 13 means that the orthographic projection of the liquid-blocking part 14 on the surface where the liquid inlet 13 is located can completely cover the liquid inlet 13.
[0037] It is understandable that when refrigerant is added to the tank 1 through the filling port 13, the liquid-blocking part 14, which is spaced apart from the filling port 13, can prevent refrigerant from splashing while not affecting the addition of refrigerant. For example, the liquid-blocking part 14 includes three baffles connected in sequence, two of which are arranged relatively parallel to each other, and the remaining baffle is connected between the two baffles. The opening formed by the three baffles faces the filling port 13. The upper end of the liquid-blocking part 14 is fixedly connected to the inner wall of the top of the tank 1, and the lower end of the liquid-blocking part 14 is suspended in the tank 1 to reduce obstruction to the flow of refrigerant.
[0038] In some embodiments, such as Figure 1 As shown, the tank body 1 is provided with a pressure relief port 16, which is located above the liquid filling port 13; the pressure relief port 16 is located on the top of the tank body 1, and the liquid filling port 13 is located on the side wall of the tank body 1 and above the upper end of the liquid level pipe 2.
[0039] Understandably, the pressure relief port 16 balances the internal and external pressures, ensuring smooth refrigerant replenishment and releasing excess pressure within the tank 1. In this embodiment, the positions of the pressure relief port 16 and the refrigerant inlet 13 reduce the likelihood of newly replenished refrigerant being ejected through the pressure relief port 16, and the liquid-blocking part 14 also serves to prevent this. The refrigerant inlet 13 is located above the upper end of the level tube 2, allowing the level tube 2 to fully function as a level indicator.
[0040] In some embodiments, such as Figure 2 As shown, the replenishment tank also includes a liquid filling pipe 4, the lower end of which is connected to the liquid filling port 13, and the upper end of which extends upward in a direction away from the tank body 1.
[0041] It is understandable that the structure of the liquid filling pipe 4 is conducive to the active flow of the refrigerant into the tank 1 under the action of gravity, and the liquid filling pipe 4 can adopt a bent pipe structure.
[0042] In some embodiments, such as Figure 2 As shown, a filter screen 15 is installed inside the box 1, and the filter screen 15 covers the liquid inlet 13.
[0043] It should be noted that when the filter screen 15 covers the liquid inlet 13, it means that the filter screen 15 is set to be attached to the surface where the liquid inlet 13 is located. In this way, all the refrigerant passing through the liquid inlet 13 is filtered by the filter screen 15, reducing impurities in the housing 1. It can be understood that when the filter screen 15 covers the liquid inlet 13, there should be a gap between the filter screen 15 and the liquid blocking part 14.
[0044] In some embodiments, such as Figure 1 As shown, the replenishment tank also includes a mounting bracket; the outer wall of the tank body 1 is provided with mounting parts 5, and two mounting parts 5 are arranged opposite each other in the vertical direction. The mounting bracket is detachably connected to the two mounting parts 5. The detachable connection method can be bolt connection, snap-fit connection, etc.
[0045] This application also provides a liquid cooling device, which includes the above-mentioned replenishment tank. The specific structure of the replenishment tank is as described in the above embodiments. Since this liquid cooling device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
