The following is a detailed description of some implementations of the present application in conjunction with the attached drawings. The following implementations and features of the implementations may be combined with each other without conflict.

Please refer to FIG. 1 and FIG. 1 to FIG. 3 . In one embodiment of the present application, a manifold 100 and a cabinet having the manifold 100 are provided. The cabinet has multiple layers and each layer is equipped with a heating element, wherein the heating element may be a processor or a storage device, etc. The manifold 100 is used to transport and recycle cooling water to the heating elements of each layer to achieve cooling of the heating elements of each layer.

The manifold 100 includes an inlet pipe 10 and an outlet pipe 20 arranged in parallel. The inlet pipe 10 is used to transport cooling water with a lower temperature to the heating element, and the outlet pipe 20 is used to recover cooling water with a higher temperature flowing out of the heating element. The length of the inlet pipe 10 extends along a first direction (X direction). The outlet pipe 20 is parallel to the inlet pipe 10 and is located on one side of the inlet pipe 10 along a second direction (Y direction), wherein the second direction is perpendicular to the first direction. In some embodiments, the inlet pipe 10 and the outlet pipe 20 are both vertically arranged inside the cabinet.

The manifold 100 has a plurality of first inlet and outlet groups 30 and a plurality of second inlet and outlet groups 40. The first inlet and outlet groups 30 and the second inlet and outlet groups 40 are respectively arranged on opposite sides of the water inlet pipe 10 and the water outlet pipe 20 along the cooperation direction (Z direction), wherein the cooperation direction is perpendicular to the first direction and the second direction, that is, one side of the water inlet pipe 10 and the water outlet pipe 20 is the first inlet and outlet group 30, and the other side is the second inlet and outlet group 40. Each first inlet and outlet group 30 includes a first water inlet 30a and a first water outlet 30b. The first water inlet 30a is arranged on the water inlet pipe 10, and the first water outlet 30b is arranged on the water outlet pipe 20. Each second inlet and outlet group 40 includes a second water inlet 40a and a second water outlet 40b. The second water inlet 40a is arranged on the water inlet pipe 10, and the second water outlet 40b is arranged on the water outlet pipe 20. Along the X direction, the distance H between each two adjacent first inlet and outlet sets 30 or each two adjacent second inlet and outlet sets 40 is the same. The distance between each two adjacent first inlet and outlet sets 30 is a first preset distance, and the distance between each two adjacent second inlet and outlet sets 40 is a second preset distance, and the first preset distance is not equal to the second preset distance.

In some embodiments, the first preset distance is 1RU of standard specification, i.e., 44.45mm, and the second preset distance is 1OU of another standard specification, i.e., 48mm. When the specifications of each layer in the cabinet are all of the standard size of RU, the side of the manifold 100 having the first inlet and outlet set 30 is used, and when the specifications of each layer in the cabinet are all of the standard size of OU, the side of the manifold 100 having the second inlet and outlet set 40 is used, so that when the height of the cabinet changes, the manifold 100 does not need to be replaced, and only needs to be rotated 180 degrees for use, thereby improving the applicability and convenience of the manifold 100 and the cabinet.

In some embodiments, the water inlet pipe 10 and the water outlet pipe 20 are both square pipes, so that holes are processed to form water inlets and water outlets.

In other embodiments, the distance between two adjacent first entrance and exit sets 30 and the distance between two adjacent second entrance and exit sets 40 may also be different and may be determined according to the needs of the cabinet.

In some embodiments, the first water inlet 30a and the first water outlet 30b both have a first diameter. The second water inlet 40a and the second water outlet 40b both have a second diameter. The first diameter is equal to or not equal to the second diameter. The manifold 100 also includes a plurality of first connectors 50 and a plurality of second connectors 60. Each first water inlet 30a and each first water outlet 30b are connected to a first connector 50, and the size of the first connector 50 matches the size of the first diameter. Each second water inlet 40a and each second water outlet 40b are connected to a second connector 60, and the size of the second connector 60 matches the size of the second diameter. The first connector 50 and the second connector 60 are used to be inserted into the interface of the heating element to transport cooling water. As an exemplary example, since the interface of a common heating element has two different standard sizes, and each standard size of the interface corresponds to a size D of a connector, the first connector 50 and the second connector 60 are respectively used to adapt to the two standard sizes.

5a and 5b, when the first diameter is not equal to the second diameter, that is, when the first connector 50 and the second connector 60 are of different sizes, the manifold 100 further includes a first adapter 91. The outer diameter of the first adapter 91 is equal to the larger one of the first diameter and the second diameter, and the inner diameter of the first adapter 91 is equal to the smaller one of the first diameter and the second diameter. Specifically, if the first connector 50 is larger and the second connector 60 is smaller, then if the smaller second connector 60 needs to be installed on the first water inlet 30a and the first water outlet 30b, the first adapter 91 needs to be installed on the first water inlet 30a and the first water outlet 30b first, and then the second connector 60 needs to be installed on the first adapter 91, as shown in FIG. 5b, thereby achieving the purpose of installing the small connector on the large port, making the small connector more universal, and improving convenience and applicability.

6a and 6b, when the first diameter is not equal to the second diameter, that is, when the first connector 50 and the second connector 60 are of different sizes, the manifold 100 further includes a second adapter 92. The outer diameter of the second adapter 92 is equal to the smaller one of the first diameter and the second diameter, and the inner diameter of the second adapter 92 is equal to the larger one of the first diameter and the second diameter. Specifically, if the first connector 50 is larger and the second connector 60 is smaller, then if the larger first connector 50 needs to be installed on the second water inlet 40a and the second water outlet 40b, the second adapter 92 needs to be installed on the second water inlet 40a and the second water outlet 40b first, and then the first connector 50 is installed on the second adapter 92, as shown in FIG. 6b, thereby achieving the purpose of installing the large connector to the small port, making the large connector more universal, and also improving convenience and applicability.

When the first diameter is equal to the second diameter, the first joint 50 and the second joint 60 are the same.

Please refer to FIG. 4 . In some embodiments, when the distance between the water inlet pipe 10 and the water outlet pipe 20 is relatively close, for example, when the distance between the water inlet pipe 10 and the water outlet pipe 20 is smaller than the diameter of the water inlet pipe 10 and the water outlet pipe 20, the manifold 100 further includes a plurality of connecting pieces 70. Each connecting piece 70 is used to connect two first joints 50 or two second joints 60 adjacent to each other along the Y direction. Each connecting piece 70 has two through holes 71. The through holes 71 are used to pass through the two adjacent first joints 50 or the two adjacent second joints 60. The connecting piece 70 is used to fix the position between the two adjacent first joints 50 or the two adjacent second joints 60, so that the overall structure of the manifold 100 is more stable.

Furthermore, in some embodiments, each connecting piece 70 has a guide pin 80 on one side away from the water inlet pipe 10 and the water outlet pipe 20, and the guide pin 80 extends along the Y direction and is located between the two through holes 71. The guide pin 80 is used to be inserted into the guide hole of the heating element, so that the heating element can move along the Y direction, thereby playing a guiding role, so that the first connector 50 and the second connector 60 can be smoothly inserted into the interface of the heating element to avoid misalignment.

Please refer to FIG. 7 . In other embodiments, when the distance between the water inlet pipe 10 and the water outlet pipe 20 is relatively far, for example, the water inlet pipe 10 and the water outlet pipe 20 are respectively arranged on two sides of the cabinet, a guide pin 80 is arranged between two first connectors 50 or second connectors 60 adjacent to each other along the X direction, and the guide pin 80 also extends along the Y direction to play a guiding role.

In some embodiments, the cabinet further includes a cabinet body and a swivel joint (not shown). The swivel joint is disposed in the cabinet body. The water inlet pipe 10 and the water outlet pipe 20 are connected to one end of the swivel joint, and the other end of the swivel joint extends out of the cabinet body to connect to an external cooling water source. The rotation axis of the swivel joint is parallel to the X direction. The manifold 100 can rotate relative to the cabinet body around the axis of the swivel joint to facilitate flipping of the manifold 100.

In some embodiments, the manifold 100 is disposed symmetrically along the rotation axis of the rotary joint and the XZ plane.

In one embodiment of the present application, a data center cooling system (not shown) is provided for cooling a plurality of cabinets. The data center cooling system includes a cooler, a cooling water inlet pipe, a hot water pipe, and a plurality of the above-mentioned cabinets. The rotary joint of each cabinet is connected to the cooling water inlet pipe and the hot water pipe, so that the water inlet pipe 10 is connected to the cooling water inlet pipe, and the water outlet pipe 20 is connected to the hot water pipe. The cooler is used to cool the water in the hot water pipe and circulate it to the cooling water inlet pipe.

The manifold 100, cabinet and data center cooling system have a first inlet and outlet set 30 and a second inlet and outlet set 40 spaced at a first preset distance and a second preset distance on opposite sides of the manifold 100, respectively. When the height of the cabinet changes, only the manifold 100 needs to be flipped over to use the size specification of the other side without replacing the manifold 100, thereby improving the convenience and efficiency of use.
