Description

Technical Field

[0001] This application relates to the field of liquid cooling equipment technology, and in particular to a liquid cooler replenishment device. Background Technology

[0002] Currently, liquid chillers are widely used in the cooling of large industrial equipment and electronic devices. The cooling principle of a liquid chiller is to transfer heat using a coolant as the heat transfer medium. Although the coolant flow channels inside a liquid chiller are closed loops, they cannot be 100% absolutely sealed. Over long-term operation, wear and tear will occur due to minor evaporation and aging of seals. If the coolant is not replenished in time, it will affect the suction capacity of the circulating pump, leading to decreased pump efficiency, increased noise, and even damage to the pump body.

[0003] Patent application number CN202323073045.5 discloses an automatic liquid replenishment device for liquid cooling equipment, which includes a mounting base, a base, a bracket, an arc-shaped support plate, a water tank, a top cover, an exhaust valve, and other structures. The entire replenishment device is large in size and is used in conjunction with liquid cooling equipment, making it difficult to move and carry. In addition, usually one refrigeration equipment is equipped with a dedicated replenishment device, which is integrated into the refrigeration equipment, making the replenishment device difficult to move and costly.

[0004] Therefore, there is an urgent need for a low-cost, portable liquid cooler replenishment device. Utility Model Content

[0005] To address the problems of current liquid replenishment devices requiring electric power and being unable to replenish liquid during power outages, as well as their large size and difficulty in relocation, this application provides a liquid cooler liquid replenishment device.

[0006] This application provides a liquid cooler replenishment device, which adopts the following technical solution: A liquid cooler replenishment device includes an exhaust tee pipe with three ports: an outlet, an exhaust port, and an inlet. The outlet is connected to the liquid cooler's replenishment port via an outlet pipe, and the inlet is connected to a liquid delivery tee pipe. The outlet is equipped with an outlet valve, the exhaust port with an exhaust valve, and the inlet with an inlet valve. The liquid delivery tee pipe has three ports: a first port, a second port, and a third port. The first port is connected to the inlet via a first single-ended pipe. The second port is connected to a container storing coolant via a second single-ended pipe, through which coolant is drawn from the container. The third port is connected to a manual pump for drawing the coolant.

[0007] By adopting the above technical solution, a portable liquid cooler replenishment device is provided. The solution has a simple structure, consisting of only multiple pipes and a manual pump, without the need for complex control and detection components. It is low in cost, small in size, and easy to carry. Liquid replenishment can be performed manually using the manual pump, which can be operated by a single person without the need for electricity, and can be completed even during power outages. The air inside the liquid cooler and replenishment device can be discharged through the exhaust port, ensuring that all injected liquid is coolant, eliminating the need for subsequent venting steps and resulting in high replenishment efficiency.

[0008] Preferably, the exhaust tee is also provided with a pressure measuring port, and the pressure measuring port is connected to a pressure gauge.

[0009] By adopting the above technical solution, the pressure inside the three-way pipe can be observed. When the power is off, the test panel of the liquid chiller cannot be used, and it is impossible to know whether the coolant is full. However, by adopting the above solution, the pressure inside the liquid chiller can be observed through the pressure gauge, and thus it can be determined whether the coolant is full.

[0010] Preferably, a first one-way valve is provided inside the first single-pass pipe, which allows the coolant to flow from the first port to the inlet and prevents the coolant from flowing from the inlet to the first port; The second one-way pipe is provided with a second one-way valve, which allows the coolant to flow from the container into the second port and prevents the coolant from flowing from the second port into the container.

[0011] By adopting the above technical solution, it is convenient to pump coolant into the exhaust tee pipe by manual pump.

[0012] Preferably, the manual pump is detachably connected to the third port.

[0013] By adopting the above technical solutions, the space occupied can be reduced and the device can be easily carried.

[0014] Preferably, the manual pump includes a cylinder, a piston, and a handle. One end of the cylinder is connected to the third port, the piston is slidably and sealingly fitted inside the cylinder, one end of the handle is connected to the piston, and the other end extends to the outside of the cylinder.

[0015] By adopting the above technical solution, the structure is simple, the cost is low, and it is convenient to pump the coolant into the exhaust tee.

[0016] Preferably, the exhaust port is connected to the container storing the coolant via an exhaust pipe.

[0017] By adopting the above technical solution, the discharged coolant can be recovered, realizing the recycling of coolant.

[0018] Preferably, the outlet tube is a transparent flexible tube.

[0019] By adopting the above technical solution, it is convenient to observe whether the air bubbles in the liquid cooler have been purged.

[0020] Preferably, a replaceable connector is provided between the liquid outlet pipe and the liquid replenishment port of the liquid chiller.

[0021] By adopting the above technical solution, it is convenient to replace different replaceable connectors according to the model of the liquid chiller, thereby adapting to different types of liquid chillers.

[0022] Preferably, the liquid outlet pipe is detachably connected to the exhaust tee pipe.

[0023] By adopting the above technical solutions, storage and transportation become convenient.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. It requires no electricity and can perform liquid replenishment even during power outages. It has a simple structure, low cost, and is easy to carry. 2. It can expel air from inside the liquid cooler through the exhaust port. Before liquid injection, it can expel air from the exhaust tee and other pipes used for injecting coolant through the exhaust port. It can inject coolant without injecting air, eliminating the need for subsequent venting steps and improving liquid replenishment efficiency. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0028] This application discloses a liquid cooler replenishment device.

[0029] Reference Figure 1A liquid cooler replenishment device includes an exhaust tee pipe 1 with three ports: an outlet 11, an exhaust port 12, and an inlet 13. The outlet 11 is connected to the liquid cooler's replenishment port via an outlet pipe 2, and the inlet 13 is connected to a liquid delivery tee pipe 3, through which coolant is delivered to the tee pipe. The exhaust port 12 is used to discharge air and excess coolant. The exhaust port 12 is connected to an exhaust pipe 6 and a container capable of holding coolant, facilitating the recovery of discharged coolant and avoiding waste. An outlet valve 111 is provided at the outlet 11, an exhaust valve 121 is provided at the exhaust port 12, and an inlet valve 131 is provided at the inlet 13. The three ports of the infusion tee 3 are a first port 31, a second port 32, and a third port 33. The first port 31 is connected to the inlet 13 via a first single-ended pipe 311. The second port 32 is connected to one end of a suction pipe 7 via a second single-ended pipe 321. The other end of the suction pipe 7 is connected to a container storing coolant, and the end of the suction pipe 7 is immersed in the coolant, allowing coolant to be drawn from the container. The third port 33 is connected to a manual pump 4 for drawing coolant. When the outlet valve 111 is opened, the manual pump 4 can manually draw coolant from the container and pump it into the liquid chiller. In the prior art, replenishment devices for replenishment equipment are often bulky and difficult to carry. Therefore, the embodiments of this application provide a replenishment device that can be operated by a single person. It is small, easy to carry, convenient for replenishment, and low in cost. It can be operated manually and does not require electricity. Temporary replenishment can be performed when the equipment is powered off or when a large replenishment device cannot operate.

[0030] Reference Figure 1 The process of replenishing coolant is as follows: First, connect the outlet pipe 2 to the replenishment port on the liquid cooler, keep the inlet valve 131 closed, open the outlet valve 111 and the exhaust valve 121, and use the internal pressure of the liquid cooler to expel the air inside the liquid cooler; after the air inside the liquid cooler is emptied, close the outlet valve 111, and then open the inlet valve 131 to supply coolant to the exhaust tee pipe 1 through the liquid delivery tee pipe 3, so that the coolant flows into the exhaust tee pipe 1 and then flows out from the exhaust port 12. This operation can expel the air in the liquid delivery tee pipe 3 and the exhaust tee pipe 1. After all the air is discharged through the exhaust port 12, close the exhaust valve 121 and open the outlet valve 111 to supply coolant into the replenishment port. Without the above operations, if coolant is directly supplied to the replenishment port through the coolant supply device, air will be introduced into the supply tee 3 and exhaust tee 1, resulting in excessive internal pressure of the liquid cooler. When the pressure is released later, the coolant will be easily discharged along with it, resulting in insufficient coolant.

[0031] Reference Figure 1The exhaust tee pipe 1 is also provided with a pressure measuring port 5, which is connected to a pressure gauge 51. In some embodiments, the exhaust tee pipe 1 can be replaced by a four-way pipe, one of which is equipped with a pressure gauge 51. The pressure gauge 51 can reflect the pressure inside the three-way valve, making it easy to see whether the coolant in each pipe is emptied or whether the valve is tightened. When supplying coolant to the liquid chiller, the pressure inside the liquid chiller can also be observed through the pressure gauge 51 to determine whether the coolant in the liquid chiller is full. Once a certain pressure is reached, the replenishment can be stopped.

[0032] Reference Figure 1 The first single-pass pipe 311 is equipped with a first one-way valve, which allows coolant to flow from the first port 31 to the inlet 13 and prevents coolant from flowing from the inlet 13 to the first port 31. The second single-pass pipe 321 is equipped with a second one-way valve, which allows coolant to flow from the container into the second port 32 and prevents coolant from flowing from the second port 32 into the container. Both the first single-pass pipe 311 and the second single-pass pipe 321 are relatively short rigid pipes. The two ends of the first single-pass pipe 311 are fixed to the first port 31 of the infusion tee pipe 3 and the inlet 13 of the vent tee pipe 1, respectively. One end of the second single-pass pipe 321 is fixed to the second port 32 of the infusion tee pipe 3, so that the infusion tee pipe 3 and the vent tee pipe 1 are connected as one unit for easy carrying. The second single-pass pipe 321 is connected to the container storing coolant through the suction pipe 7. The suction pipe 7 is a flexible tube with one end connected to the second port 32 and the other end placed in the container containing coolant and immersed in the coolant for easy suction. The suction pipe 7 is detachable from the second single-pass pipe 321. When not in use, the suction pipe 7 can be removed for easy storage and transportation. It is also convenient to replace the coolant in a timely manner if it is damaged.

[0033] Reference Figure 1 The manual pump 4 includes a cylinder 41, a piston 42 and a handle 43. The cylinder 41 is a cylindrical hollow cylinder. One end of the cylinder 41 is detachably sealed to the third port 33 by bolts. The piston 42 is slidably sealed inside the cylinder 41. One end of the handle 43 is connected to the piston 42, and the other end extends to the outside of the cylinder 41. When coolant needs to be pumped in, pull handle 43 by hand. The piston 42 moves away from the third port 33, creating negative pressure in the cylinder and the liquid delivery tee 3. Since the first port 31 is equipped with a first single-pass pipe 311, the first port 31 is closed. The coolant flows into the liquid delivery tee 3 and the cylinder through the second single-pass pipe 321. Then, push handle 43 forward to squeeze the coolant in the liquid delivery tee 3 and the cylinder. Since the second port 32 is equipped with a second single-pass pipe 321, the second port 32 is closed. The coolant can only flow out from the first port 31 and into the inlet 13.

[0034] Reference Figure 1 The manual pump 4 is detachably connected to the third port 33. When storing or carrying it, the manual pump 4 can be detached from the third port 33 to avoid excessive overall size and make it more convenient to carry. Furthermore, the manual pump 4 can rotate around the third port 33, allowing free adjustment of the angle of the cylinder 41. When pumping coolant, the cylinder 41 can be stood upright on the ground, one hand supporting the cylinder 41, and the other hand pressing the handle 43, pumping coolant in a manner similar to a bicycle pump – less strenuous and easier to operate.

[0035] Reference Figure 1 The outlet pipe 2 is a transparent flexible tube, which allows for easy observation of air bubbles inside the liquid chiller when air is expelled. A replaceable connector 8 is provided between the outlet pipe 2 and the liquid chiller's inlet. The replaceable connector is selected according to the model of the liquid chiller's inlet, and the replaceable connector 8 can be detachably and sealingly connected to the outlet pipe 2.

[0036] Reference Figure 1The specific operation process of the liquid cooler replenishment device in this embodiment is as follows: First, assemble all the components of the replenishment device, then close all valves, connect the outlet pipe 2 to the replenishment port on the liquid cooler through the replaceable connector 8, prepare a container for holding coolant, insert the end of the exhaust pipe 6 into the container for holding coolant, and connect the suction pipe 7 to the container for holding coolant; open the ball valve on the liquid cooler by 1 / 3 to connect the replenishment port with the coolant inside the liquid cooler, and then open the outlet valve 111. At this time, under the pressure inside the liquid cooler, Air and some coolant inside the liquid chiller flow into the outlet pipe 2. The outlet pipe 2 is a transparent flexible tube, allowing observation of the coolant and air bubbles within it. The pressure inside the liquid chiller can be observed using pressure gauge 51, and experienced operators can use this gauge to assess the internal condition. Next, the vent valve 121 is slowly opened a small gap, allowing air and coolant carrying air bubbles to be discharged through the vent port 12 into the coolant container. At this point, the entire vent tee pipe 1 is raised and gently shaken to accelerate the discharge. The speed at which air bubbles are expelled from pipe 2 is such that when the air bubbles inside pipe 2 are emptied, the outlet valve 111 is closed. At this time, the air inside the liquid cooler is emptied, and the pressure inside the liquid cooler is relatively low. Then, the entire device is placed on the ground, and the cylinder 41 is rotated to find a suitable direction for pressing the handle 43. After that, the inlet valve 131 is opened, and the coolant in the container is pumped into the inlet tee pipe 3 and the outlet tee pipe 1 by pushing and pulling the handle 43. Since the outlet pipe 2 is still closed, the coolant will flow back into the container through the outlet 11. The continuous flow of coolant ensures that there is no air in the inlet tee 3, the first single-way pipe 311, and the vent tee 1, thus purging the air from the supply pipes. Then, the vent valve 121 is closed, the outlet valve 111 is opened, and coolant is pumped into the liquid chiller using the manual pump 4. Since the air inside the liquid chiller and the supply pipes has been purged beforehand, only coolant is pumped in, and no air is introduced. During the pumping process, the pressure gauge 51 is continuously monitored. Once the required pressure is reached, the ball valve on the liquid chiller is closed, completing the replenishment. After replenishment, the vent valve 121 is opened, allowing all the coolant in the pipes to flow into the container. The replaceable connector 8 on the replenishment port can then be removed. The entire replenishment process can be operated by a single person. Excess coolant is recovered into the container, preventing waste, and no air is pumped in during replenishment, eliminating the need for subsequent venting steps and resulting in higher replenishment efficiency.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
