[0002] With the innovative development of technologies such as artificial intelligence, cloud computing, big data, and blockchain, the 5G communication era, characterized by high speed, low latency, and large connections, has arrived. As information infrastructure, data centers and communication equipment are shouldering an increasing amount of computing power. In addition to the huge energy consumption problem, high heat density also puts higher demands on refrigeration equipment and technology. Traditional air cooling technology presents a bottleneck in high heat density scenarios, and the heat dissipation efficiency can no longer keep up with the computing efficiency. In this context, liquid cooling technology has attracted widespread attention and wide application in the industry with its ultra-high energy efficiency and ultra-high heat density. However, improperly designed connectors cannot meet the needs of data center operation and maintenance, which will bring unnecessary troubles in the later stage.

[0003] In order to ensure the long-term safety and reliability of the entire liquid cooling pipeline, the connection of the fluid connector is an important link. The patent document (CN213871607U) discloses a blind plug fluid connector, which includes a plug and a socket, that is, a male head and a female head. When the plug is connected to the socket, the front end of the second valve sleeve extends into the first valve sleeve through the action of external force, and pushes the first valve core to move backward, the first valve core squeezes the first spring, and the front end of the inner core extends into the second valve sleeve and pushes the second valve core to move backward, the second valve core squeezes the second spring, and the plug and the socket are connected. However, in the prior art, due to some reasons, the male head and the female head are not coaxial, and when the male head and the female head are connected, the male head and the female head cannot be connected. Summary of the invention

[0004] The utility model aims to provide a through-the-wall floating fluid connector, which solves the technical problem in the prior art that male and female heads cannot be connected due to different axes.

[0005] A wall-penetrating floating fluid connector of the present utility model includes a female head and a male head. The female head includes a wall fixing sleeve, in which a pressure sleeve is fixedly arranged. A floating sleeve is arranged below the pressure sleeve in the wall fixing sleeve. An annular X-axis floating gap is arranged between the floating sleeve and the wall fixing sleeve. A valve sleeve is fixedly arranged in the floating sleeve. A conical surface is arranged at the upper opening of the valve sleeve. A first spring is arranged between the outer circumferential surface of the valve sleeve and the inner circumferential surface of the pressure sleeve. An inner core is coaxially and fixedly arranged in the valve sleeve. The lower end of the inner core is fixedly connected to the valve sleeve. The upper end of the inner core extends upward and there is a gap between the inner core and the valve sleeve. An axial channel is arranged at the bottom of the inner core. A first valve core is also arranged in the valve sleeve. The first valve core is sleeved on the inner core. A second spring is arranged between the lower side of the first valve core and the inner core. The second spring biases the first valve core upward. A second valve core that cooperates with and contacts the inner core is arranged in the male head. A third spring is arranged between the second valve core and the inside of the male head. The third spring biases the second valve core downward.

[0006] Further, the second spring is a circular spring or a triangular spring.

[0007] Further, a Z-axis floating gap is also arranged between the floating sleeve and the wall fixing sleeve. A fourth spring is arranged between the floating sleeve and the wall fixing sleeve.

[0008] Compared with the prior art, the effects of the present utility model are positive and obvious. In a wall-penetrating floating fluid connector of the present utility model, the X-axis floating gap and the Z-axis floating gap between the valve sleeve and the wall fixing sleeve enable the floating sleeve to float on the X-axis and the Z-axis. When the male and female heads are not coaxial, they can still be inserted. When the male and female heads are disconnected, the female head can automatically return to its original position through the spring, realizing three-axis floating insertion.

An inner core 9 is coaxially and fixedly arranged in the valve sleeve 6, the lower end of the inner core 9 is fixedly connected to the valve sleeve 6, the upper end of the inner core 9 extends upward and there is a gap between the inner core 9 and the valve sleeve 6. A channel along the axial direction (not shown in the figure) is arranged at the bottom of the inner core 9. A first valve core 10 is also arranged in the valve sleeve 6, the first valve core 10 is sleeved on the inner core 9, and a second spring 11 is arranged between the lower side of the first valve core 10 and the inner core 9. The second spring 11 biases the first valve core 10 upward. A second valve core (not shown in the figure) that cooperates with the inner core 9 is arranged in the male head 1, and a third spring (not shown in the figure) is arranged inside the male head 1. The third spring biases the second valve core downward.

[0014] Specifically, the specific structure of the male head 1 adopts the relevant structure of the patent document (CN213871607U), which will not be elaborated here.

[0015] Further, the second spring 11 is a circular spring or a triangular spring.

[0016] Further, a Z-axis floating gap 16 is also arranged between the floating sleeve 4 and the wall fixing sleeve 2, and a fourth spring 12 is arranged between the floating sleeve 4 and the wall fixing sleeve 2.

[0017] Specifically, the valve sleeve 6, the circular spring, the triangular spring, etc. in this embodiment all adopt well-known solutions in the prior art, and those skilled in the art have already understood them, which will not be elaborated here.

[0018] The working principle of this embodiment:

[0019] Connection process between the female head and the male head 1: The wall fixing sleeve 2 is fixed in the wall 13, the lower end of the floating sleeve 4 is connected to the lower device interface 14 through a thread, the male head 1 is connected to the upper device interface 15 through a thread. Through an external force, the male head 1 is inserted into the valve sleeve 6 and guided by the conical surface 7. If the male head 1 and the valve sleeve 6 are not coaxial, the valve sleeve 6 and the floating sleeve 4 use the X-axis floating gap 5 and the Z-axis floating gap 16 for adaptive floating to make the valve sleeve 6 and the male head 1 coaxial. The first spring 8 and the fourth spring 12 are compressed. After the male head 1 is inserted into the valve sleeve 6, it pushes the first valve core 10 downward, and the second spring 11 is compressed. At the same time, the inner core 9 extends into the male head 1. When it reaches a certain depth, it is fixed statically. A flow channel is formed in the male head 1 and the female head, and the flow channel direction is as Figure 2As shown, the coolant is smoothly transmitted through the flow channel to take away the heat of the equipment.

[0020] Process of disconnecting the female head from the male head 1: When the equipment is separated, the female head can be disconnected from the male head 1, and the first spring 8 and the fourth spring 12 reset the valve sleeve 6. The first valve core 10 can slide and rebound freely within the valve sleeve 6 to ensure no loosening.

[0021] For a wall-penetrating floating fluid connector of the present utility model, the X-axis floating gap 5 and the Z-axis floating gap 16 between the valve sleeve 6 and the wall fixed sleeve 2 enable the floating sleeve 4 to float on the X-axis and the Z-axis. When the male and female heads are not coaxial, they can still be inserted. When the male and female heads are disconnected, the female head can automatically return to its original position through the spring, achieving three-axis floating insertion.
