The quick connector is an important part of the liquid cooling system, and plays a role in connecting and disconnecting a loop so as to facilitate installation and maintenance of the liquid cooling system.
The quick connector used in the current liquid cooling system is easy to leak, and particularly when the diameter of impurity particles mixed with liquid in the liquid cooling system is larger than 100mm, the liquid leakage condition is easy to occur; because the large-diameter impurity particles in the liquid can affect the contact between the sealing ring in the quick connector and the shell of the quick connector under the pressurization of the liquid cooling system, the liquid is easy to leak from the gap between the sealing ring and the shell under the large internal pressure.
Currently, there are two reasons for the deterioration of the liquid quality (which is reflected by the larger diameter of the impurity particles): 1. when the flow rate of the liquid is too high, the surface of the pipeline is washed for a long time, so that metal and nonmetal particles are easily separated out; 2. the joint is polluted by the outside; there are correspondingly two solutions: 1. reducing the liquid flow rate; 2. the liquid is replaced periodically.
However, the first solution described above may affect the refrigeration efficiency of the liquid cooling system, and the second solution requires regular maintenance, which reduces the refrigeration time of the liquid cooling system and also reduces the refrigeration efficiency of the liquid cooling system; that is, the quick coupling in the prior art cannot prevent the liquid leakage on the premise of ensuring the refrigeration efficiency.

Example one
The anti-leakage quick connector provided by the embodiment is applied to a liquid cooling system, and the liquid cooling system is mainly used for a server and a communication cabinet, wherein the structure of the anti-leakage quick connector is improved, so that the sealing performance of the anti-leakage quick connector can be improved on the premise of ensuring the refrigeration efficiency of the liquid cooling system.
As shown in fig. 1 and 2, the leakage-proof quick connector of the present embodiment includes a housing unit 10, and a flow channel 11 configured with an internal connection port 12 and an external connection port 13 is formed in the housing unit 10. Wherein the internal connecting port 12 is communicated with a flow path outlet or a flow path inlet in the liquid cooling system, and the external connecting port 13 can be connected with the external connecting port 13 of other leakage-proof quick connector or externally connected to other equipment.
Between the internal connection port 12 and the external connection port 13, the housing unit 10 is slidably connected with a first piston unit 20 and a second piston unit 30 in sequence, and the first piston unit 20 and the second piston unit 30 divide the flow passage 11 into a first sealed cavity 14, a second sealed cavity 15 and a communication cavity 16. The second sealed cavity 15 is hermetically connected to the first sealed cavity 14 and the communicating cavity 16.
When the housing unit 10 is mounted, the first piston unit 20 and the second piston unit 30 slide in the direction approaching the internal connection port 12, and the first sealed chamber 14, the second sealed chamber 15, and the communication chamber 16 communicate. It should be noted that, when the housing unit 10 is installed, the first piston unit 20 and the second piston unit 30 slide under an external force, for example, two second piston units 30 in two leak-proof quick couplings in fig. 3 abut against each other and slide toward the corresponding internal connection ports 12, so that the first sealed cavity 14, the second sealed cavity 15 and the communication cavity 16 are communicated.
Specifically, when the anti-leakage quick connector is not connected with other components, the first piston unit 20 and the second piston unit 30 separate the flow channel 11 to form a first sealed cavity 14, a second sealed cavity 15 and a communication cavity 16, so that secondary anti-leakage is formed between the internal connecting port 12 and the external connecting port 13; when the liquid in the first seal cavity 14 accidentally flows out from the first seal cavity 14 under the conditions that the quality of the liquid is low and the internal fluid pressure is too large, the liquid can flow into the second seal cavity 15, and when the liquid flows through the first piston unit 20, the fluid pressure can be obviously reduced, namely the fluid pressure in the second seal cavity 15 is small, the risk of liquid leakage is obviously reduced, and therefore the sealing reliability of the leakage-proof quick joint is obviously improved; in the process, through the design of secondary leakage prevention, even if the diameter of the impurity particles of the liquid is increased, the liquid is difficult to leak out of the leakage-preventing quick connector, so that the flow rate of the liquid is not required to be reduced or the liquid is required to be replaced periodically, the refrigeration efficiency is ensured, and the leakage-preventing quick connector and the liquid cooling system can prevent the liquid leakage on the premise of ensuring the refrigeration efficiency.
Further, as shown in fig. 2 to 5, the first piston unit 20 includes a first piston body 21 and a first seal ring 22 embedded on the first piston body 21.
The second piston unit 30 includes a second piston body 31 and a second seal ring 32 fitted on the second piston body 31.
A first wall surface 111 that can be brought into contact with the first seal ring 22 and a second wall surface 112 that can be brought into contact with the second seal ring 32 are formed on the wall surface of the flow passage 11. When the housing unit 10 is mounted, the first piston unit 20 and the second piston unit 30 slide in a direction close to the internal connection port 12, so that a gap occurs between the first seal ring 22 and the first wall surface 111, and a gap occurs between the second seal ring 32 and the second wall surface 112, so that the first seal cavity 14, the second seal cavity 15, and the communication cavity 16 communicate.
In a specific embodiment, a first guide post 23 is convexly disposed on a side of the first piston body 21 close to the second piston body 31, a first guide groove 33 is disposed at a position of the second piston body 31 corresponding to the first guide post 23, and the first guide post 23 is slidably sleeved in the first guide groove 33.
In other optional embodiments, a guide groove is formed in one side of the first piston body 21 close to the second piston body 31, a guide post is convexly arranged at a position of the second piston body 31 corresponding to the guide groove, and the guide post is movably sleeved in the guide groove.
Further, the first guide post 23 is sleeved with a first pressure spring 40, one end of the first pressure spring 40 abuts against the first piston body 21, and the other end of the first pressure spring 40 abuts against the second piston body 31. The first compression spring 40 serves to make the second seal ring 32 contact the second wall surface 112 more closely, thereby enhancing the sealing performance when the housing unit 10 is not mounted.
In a particular embodiment, the projection of the second piston body 31 in the direction of approaching the first piston body 21 falls completely into the first piston body 21. The diameter of the first wall 111 is larger than the diameter of the second wall 112. It should be noted that, the first piston body 21 has a larger contact area with the flow channel 11 than the second piston body 31, so that when the fluid passes through the first piston unit 20, the pressure of the fluid can be further reduced, and after the fluid enters the second seal cavity 15, because the contact area between the second piston body 31 and the flow channel 11 is small, the fluid is more difficult to flow out of the second seal cavity 15, thereby integrally improving the sealing performance of the leak-proof quick connector.
Further, a fixing member 50 is embedded in the end of the housing unit 10 away from the external connection port 13, the internal connection port 12 is opened on the fixing member 50, and the first piston unit 20 is slidably connected to the fixing member 50.
In a specific embodiment, a second guiding column 24 is convexly disposed on one side of the first piston body 21 close to the fixing element 50, a second guiding groove 51 is disposed at a position of the fixing element 50 corresponding to the second guiding column 24, and the second guiding column 24 is slidably sleeved in the second guiding groove 51.
In another specific embodiment, a guide groove is formed on one side of the first piston body 21 close to the fixing element 50, and a guide post is formed on the fixing element 50 at a position corresponding to the guide groove and slidably sleeved in the guide groove.
It should be noted that, in a specific embodiment, a first guide post 23 is convexly disposed on one side of the first piston body 21 close to the second piston body 31, a first guide groove 33 is disposed on the second piston body 31 corresponding to the first guide post 23, and the first guide post 23 is slidably sleeved in the first guide groove 33; a second guide post 24 is convexly arranged on one side of the first piston body 21 close to the fixing piece 50, a second guide groove 51 is formed in the position, corresponding to the second guide post 24, of the fixing piece 50, and the second guide post 24 is slidably sleeved in the second guide groove 51; in particular, the guide posts are all disposed on the first piston body 21, which can improve the overall quality of the first piston body 21, and is beneficial to further reducing the pressure of the fluid passing through the first piston unit 20, thereby preventing the fluid from flowing out of the second seal cavity 15.
Further, a second pressure spring 60 is sleeved outside the second guide groove 51, one end of the second pressure spring 60 abuts against the first piston body 21, and the other end of the second pressure spring 60 abuts against the fixing member 50. The second pressure spring 60 plays a role in sealing between the first seal ring 22 and the first wall surface 111.
On the basis of the above embodiments, the leakage-proof quick connector of the present embodiment includes two types, one is a leakage-proof male head as shown in fig. 1, and the other is a leakage-proof female head as shown in fig. 2, and the leakage-proof male head can be inserted into the leakage-proof female head. The difference between the anti-leakage female head and the anti-leakage male head is that the housing unit 10 of the anti-leakage female head comprises an inner housing 101 and an outer housing 102 sleeved outside the inner housing 101, a third spring 19 is sleeved between the inner housing 101 and the outer housing 102, and the third spring 19 provides elastic force along the sliding direction of the piston unit for the inner housing 101 and the outer housing 102, so that the respective housing units 10 can be tightly connected when the anti-leakage male head is connected with the anti-leakage female head; meanwhile, for the anti-leakage female head, a third sealing ring 17 is also arranged on the bottom wall of the communicating cavity 16, so that the sealing property when the anti-leakage male head is connected with the anti-leakage female head is enhanced; the fourth sealing ring 18 is embedded in the inner side shell 101, the leakage-proof male head is provided with a mounting groove corresponding to the fourth sealing ring 18, when the leakage-proof male head is connected with the leakage-proof female head, the fourth sealing ring 18 is partially clamped in the mounting groove, and the stability of connection of the leakage-proof male head and the leakage-proof female head is improved.
