Description

Technical Field

[0001] The present invention relates to the field of liquid cooling technology, and more specifically, to a liquid cooling manifold, and also to a liquid cooling system comprising the liquid cooling manifold. Background Art

[0002] The rapid growth of computing demand in data centers and the rapid increase of heat dissipation demand in fields such as energy storage have led to higher and higher requirements for heat dissipation efficiency. At present, liquid cooling has gradually replaced air cooling as the main heat dissipation method for heat sources in data centers, energy storage and other fields. Taking the data center as an example, in the liquid cooling system of the data center, a piping system is required to realize the transmission of coolant working fluid to achieve heat transfer from the secondary side to the primary side. In the piping system, a pipe manifold is required to realize the connection between multiple cold plates and CDU, where the inlet and outlet of the cold plate are connected to the branch interface of the manifold through a smaller pipe, and then a thicker pipe is used to connect the total inlet / outlet of the manifold to the CDU or other pipelines. The liquid cooling piping system of the energy storage system also has a similar piping structure.

[0003] At present, most manifolds in data centers are made of metal pipes. External joints with branch interfaces are welded on the metal pipes. The external joints are used to connect to the cold plate. It is necessary to process holes for the water distribution ports on the side of the pipe and then weld the corresponding interfaces. The large number of welding positions leads to low manufacturing process efficiency. In addition, when there are many welding positions, the structure is prone to welding deformation. If the welding is poor, there will be a risk of leakage. In addition, the use of metal structures also leads to higher weight and cost of the entire piping system.

[0004] Moreover, the existing metal manifolds have a large number of welding positions. The limitation of the welding structure makes automated welding difficult. When the welding quality consistency is poor under manual welding, leakage occurs at the welding position. On the other hand, when the welding positions are dense, the welding deformation of the entire manifold is not easy to control; the metal pipe and welding structure lead to relatively high processing costs and a large overall weight of the pipeline; in addition, the metal pipeline also faces corrosion problems.

[0005] In the process of realizing the invention, the inventors found that there are at least the following problems in the prior art: the connection effect between the external joint of the liquid cooling manifold and the pipe body is not good. Summary of the invention

[0006] In view of this, the first object of the present invention is to provide a liquid cooling manifold, which can effectively solve the problem of poor connection between the external joint and the pipe body of the liquid cooling manifold in the prior art.

[0018] In some technical schemes, the polymer material adapter includes a first cylindrical portion and an inner boss, the inner boss is arranged at one end of the first cylindrical portion away from the tube cavity of the polymer material tube body, the inner boss is out of the inner wall of the first cylindrical portion, the metal adapter is cylindrical, located on the inner side of the first cylindrical portion and connected to each other; the end of the metal adapter away from the tube cavity abuts against the side of the inner boss close to the tube cavity; the side of the polymer material adapter away from the tube cavity abuts against the upper limit shoulder surface of the metal external joint through a first sealing ring.

[0034] The embodiment of the present invention discloses a liquid cooling manifold, which effectively solves the problem of poor connection effect between the external joint and the pipe body of the liquid cooling manifold in the prior art.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In some embodiments, a liquid cooling manifold is provided, which may also be called a manifold or a water distributor or a water collector. Specifically, the liquid cooling manifold includes a polymer material tube body 1, a polymer material adapter 2 and a metal adapter 3, and a metal external connector 4 may or may not be provided.

[0038] The polymer material tube body 1 and the polymer material adapter 2 are both polymer material parts. The polymer material part refers to the polymer material part whose main material or all materials are polymer materials. However, the polymer material tube body 1 and the polymer material adapter 2 can be made of the same polymer material, or they can be made of different polymer materials respectively, and preferably, the main material components of the two are the same. The polymer material is such as plastic, rubber, etc., so the polymer material tube body 1 can be a plastic tube body, and the polymer material adapter 2 can be a plastic adapter. The polymer material tube body 1 refers to a tubular polymer material part; and the polymer material adapter 2 refers to a polymer material part used for transfer. The specific structure used for transfer is as shown in the following embodiment, or it can be other structures.

[0039] The corresponding metal adapter 3 and metal external connector 4 are both metal structures, and the material of the metal structure can be an alloy, preferably copper structure, aluminum structure or cast iron structure; of course, the metal adapter 3 and the metal external connector 4 can be made of the same metal material or different metal materials. The metal adapter 3 refers to a connector made of metal and used for connection, while the metal external connector 4 refers to a connector made of metal and used for external connection with other structures.

[0040] The polymer material tube body 1 has an inner cavity, i.e., a tube cavity 12, and has at least one mounting through hole 11. For the convenience of explanation, the extension direction of the polymer material tube body 1 is taken as the first direction; and the extension direction of the mounting through hole 11 is taken as the second direction. Taking a cylindrical structure as an example, the extension direction generally refers to the axial direction. The first direction and the second direction are generally arranged vertically, but of course they can also be arranged non-vertically. The mounting through hole 11 is arranged through, i.e., one end extends to the tube cavity 12, and the other end extends to the outer wall.

[0041] The polymer material adapter 2 is inserted into the installation through hole 11 and fixedly connected therebetween, and the fixed connection method includes connection processes such as hot melt connection, ultrasonic welding, and bonding. Generally, the outer wall of the polymer material adapter 2 and the inner hole wall of the installation through hole 11 are sealed and connected, and the connection is formed based on connection processes such as hot melt connection, ultrasonic welding, and bonding.

[0042] The metal adapter 3 is injection molded and embedded in the polymer material adapter 2, that is, embedded in the polymer material adapter 2 and connected by injection molding. That is, the polymer material adapter 2 is an injection molded part. During injection molding, the metal adapter 3 is placed in advance, and then the injection molding material is introduced to mold the polymer material adapter 2. Because of injection molding, a high-strength connection can be formed between the metal adapter 3 and the polymer material adapter 2. In order to achieve better bonding, a convex structure can be formed on the surface of the metal adapter 3 to further embed it into the polymer material adapter 2 to increase the bonding strength; of course, the roughness of the contact surface between the metal adapter 3 and the polymer material adapter 2 can also be increased; as shown in the attached Figure 2 , 4 As shown, the outer wall of the metal adapter 3 has a toothed structure so as to be embedded in the polymer material adapter 2 to improve the supporting strength in the second direction.

[0043] The metal adapter 3 is used for detachable fixed connection with the external structure, that is, it can have a detachable connection part, such as a thread, a clamping structure, to achieve threaded connection, clamping, etc. When a metal external joint 4 is further provided, the metal external joint is detachably connected to the detachable connection part, that is, a connection part is correspondingly provided to form a detachable connection pair with the detachable connection part, such as internal and external threads, and two clamping structures that match. The metal external joint 4 can be one end of a quick-connect connector, such as a male connector. The metal external joint 4 forms a hole connected to the tubular cavity 12. It should be noted that the hole of the metal external joint 4 can extend to the tubular cavity 12, or it can not extend to the tubular cavity 12, so that it is connected through the partial cavity of the installation through hole 11 and / or the partial cavity of the polymer material adapter 2 and / or the partial cavity of the metal adapter 3.

[0044] In the above-mentioned liquid cooling manifold, during manufacturing, it is only necessary to open a mounting through hole 11 on the polymer material tube body 1, and the polymer material adapter 2 is injection molded on the metal adapter 3 to form an injection molding assembly, and then the injection molding assembly is inserted into the mounting through hole 11, and the polymer material tube body 1 and the polymer material adapter 2 are connected. The connection here is the connection of the polymer material, and the connection is relatively convenient. Subsequently, the metal external joint 4 can be connected. Since the metal external joint 4 and the metal adapter 3 are both made of metal materials, a stronger connection can be achieved in the detachable connection, and the service life is good. Compared with adding the metal adapter 3 when directly injection molding the polymer material tube body 1, the polymer material adapter 2 and the metal adapter 3 are first injection molded, and then the polymer material tube body 1 and the polymer material adapter 2 are connected. The overall manufacturing cost is significantly reduced, and the strength can be guaranteed. In summary, the liquid cooling manifold can effectively solve the problem of poor connection between the external joint and the tube body of the liquid cooling manifold in the prior art.

[0045] In some embodiments, the metal adapter 3 and the metal external connector 4 can be made of the same material. Considering that the cooling liquid may have a certain electrochemical corrosiveness, the same material is used here to effectively avoid electrochemical corrosion between dissimilar metals.

[0046] In some embodiments, the polymer material tube body 1 and the polymer material adapter 2 are made of the same material, and can have better connectivity when fixedly connected by hot melt connection, ultrasonic welding or bonding. The polymer material tube body 1 and the polymer material adapter 2 can both be PPE structures (PPE (polyphenylene ether) is a thermoplastic engineering plastic with excellent comprehensive properties).

[0047] In some embodiments, the polymer material tube body 1 can be arranged with multiple mounting through holes 11 in sequence along the extension direction of the tube body (the above-mentioned first direction), and each of the mounting through holes 11 is provided with a joint assembly to form a branch interface respectively, and the joint assembly includes the above-mentioned polymer material adapter 2, the metal adapter 3 and the metal external joint 4.

[0048] In some embodiments, one end of the polymer material tube body 1 is closed and the other end is connected to a main joint 8, wherein the main joint 8 can be a metal joint or a polymer material joint. Since it does not need to bear a large connection strength here, the strength requirement is not high. When the liquid cooling manifold is used as a water collector, the main joint 8 is the main liquid discharge port; and when the liquid cooling manifold is used as a water distributor, the main joint 8 is the main liquid inlet. The polymer material tube body 1 can be closed by an end cap 7, and the end cap 7 is preferably a polymer material end cap, and the end cap 7 and the polymer material tube body 1 are fixedly connected by hot melt connection, ultrasonic welding or bonding. Preferably, the connection method between the end cap 7 and the polymer material tube body 1 is the same as the connection method between the polymer material adapter 2 and the polymer material tube body 1. The corresponding main joint 8 and the polymer material tube body 1 are fixedly connected by hot melt connection, ultrasonic welding or bonding.

[0049] In some embodiments, as shown in the attached Figure 1 , 2 As shown, the cross section of the polymer material tube body 1 can be made into a square frame shape; a mounting through hole 11 is arranged in the center of the tube wall of one side of the polymer material tube body 1 in the circumferential direction, such as Figure 2 A mounting through hole 11 is provided in the middle of the right tube wall in the up-down direction. A square frame-type polymer material tube body 1 is used, which is more conducive to setting the mounting through hole 11 and better ensuring the connection effect between the mounting through hole 11 and the polymer material adapter 2. The cross section of the polymer material tube body 1 can be a square frame. In order to facilitate installation, it is preferred that the cross section of the polymer material tube body 1 is a rectangular frame, and the above-mentioned mounting through hole 11 is provided on the long side. The mounting through hole 11 can be provided only on one side of the long side to facilitate installation, or the mounting through holes 11 can be provided on both sides of the long side of both sides to reduce the volume and achieve a better diversion effect. The long side refers to the side corresponding to the long side of the rectangle, which is arranged adjacent to the short side.

[0050] Furthermore, the wall thickness of the tube on one side where the mounting through hole 11 is provided may be greater than that of the tube on other sides, so as to ensure the supporting strength of the interface assembly.

[0051] In some embodiments, Figure 3 , 4As shown, the cross section of the lumen 12 of the polymer material tube body 1 can be made circular. The lumen 12 can have better pressure bearing capacity and smaller flow resistance. One side of the outer contour of the polymer material tube body 1 is a circular arc structure 14, and the other side is a square platform structure 13 protruding outward. A cylindrical mounting through hole 11 is opened in the middle of the square platform structure 13; the circular arc structure 14 is coaxially arranged with the lumen 12, and the axis of the mounting through hole 11 is perpendicular to the axis of the lumen 12 and arranged in the same plane. By adding a square platform structure 13 on one side, it is convenient to set the mounting through hole 11, and then to install the joint assembly, which includes the above-mentioned polymer material adapter 2, metal adapter 3 and metal external joint 4. The square platform structure not only facilitates the installation of the interface assembly, but also enhances the strength of this side. The width of the square platform structure 13 is set corresponding to the diameter of the mounting through hole 11, and the wall thickness here, that is, the minimum distance between the mounting through hole wall and the side wall of the square platform structure, should be equal to or nearly equal to the wall thickness at the circular arc structure 14. Generally speaking, the diameter of the mounting through hole 11 can be made smaller than the diameter of the tube cavity 12 .

[0052] In some embodiments, Figure 4 , 5 As shown, the polymer material adapter 2 can include a first cylindrical portion 21 and an inner boss 22, wherein the inner boss 22 is arranged at one end of the first cylindrical portion 21 away from the tube cavity 12 of the polymer material tube body 1, that is, the inner boss 22 is located at the end of the first cylindrical portion 21 away from the tube cavity 12 in the first direction. The inner boss 22 is located on the inner wall of the first cylindrical portion 21 to form an inward shoulder, and the metal adapter 3 is cylindrical, located on the inner side of the first cylindrical portion 21 and connected to each other, that is, a sealed connection formed by injection molding. The end of the metal adapter 3 away from the tube cavity 12 abuts against the side of the inner boss 22 close to the tube cavity 12, that is, the end of the metal adapter 3 away from the tube cavity 12 in the first direction abuts against the inner boss 22, and the end close to the tube cavity 12. The side of the polymer material adapter 2 away from the lumen 12 abuts against the upper limit shoulder surface 41 of the metal external joint 4 through the first sealing ring 5, and specifically, the side of the inner boss 22 away from the lumen 12 abuts against the upper limit shoulder surface 41 of the metal external joint 4 through the first sealing ring 5. At this time, the limit shoulder surface 41 of the metal external joint 4 and the metal adapter 3 form a clamping effect on the inner boss 22, reducing the connection strength between the metal adapter 3 and the polymer material adapter 2.

[0053] The metal adapter 3 may be a cylindrical tube with threads both inside and outside. The internal threads are used to connect with the metal external connector 4, while the external threads are used to embed in the polymer material adapter 2 to enhance the connection between the two.

[0054] Furthermore, the polymer material adapter 2 may further include a first outer boss 23, which protrudes from the outer wall of the first cylindrical portion 21, wherein the first outer boss 23 is located outside the polymer material tube body 1 and abuts against the outer hole end of the mounting through hole 11, so that when the metal external joint 4 is plugged in, the above-mentioned abutment relationship can withstand a certain pressure in the second direction to improve the overall strength. In particular, when the polymer material tube body 1 is provided with the above-mentioned square platform structure 13, the abutment strength that can be borne is relatively large to improve the overall strength.

[0055] In some embodiments, the metal adapter 3 can include a second cylindrical portion 31 and a second external boss 32; wherein the second external boss 32 is located at the end of the second cylindrical portion 31 away from the tube cavity 12 of the polymer material tube body 1. The second external boss 32 protrudes from the outer wall of the second cylindrical portion 31. The polymer material adapter 2 is cylindrical. The polymer material adapter 2 surrounds the outside of the second cylindrical portion 31 and is connected to each other. The end of the polymer material adapter 2 away from the tube cavity 12 abuts against the second external boss 32 to transmit the abutment force in the second direction, that is, through the abutment, it bears a part of the plug-in pressure of the metal external connector 4.

[0056] The outer wall of the polymer material adapter 2 and the outer wall of the second outer boss 32 are both against the inner wall of the mounting through hole 11; the metal adapter 3 is against the upper limit shoulder surface 41 of the metal external joint 4 through the second sealing ring 6.

[0057] In the above arrangement, the polymer material adapter 2 can be well embedded and installed, so that the polymer material adapter 2 has better concealment.

[0058] The outer cylinder wall of the second cylindrical portion 31 may be provided in a threaded structure to be embedded into the inner wall of the polymer material adapter 2 to present a better bonding strength.

[0059] To further improve the strength, the second outer boss 32 may be abutted against the outer end of the mounting through hole 11 so that the polymer material tube body 1 bears a portion of the pressure.

[0060] In some embodiments, the inner ends of the polymer material adapter 2, the metal adapter 3 and the metal external connector 4 may not extend into the lumen 12 but only be located in the mounting through hole 11 to prevent the fluid from flowing in the lumen.

[0061] In some embodiments, as shown in the attached Figure 1, a square hollow tube is provided as a polymer material tube body 1, the inner cavity cross-section of the square hollow tube is rectangular, and the material of the square hollow tube is polyphenylene ether (PPE); an end cap 7 of the same material is used at one end of the square hollow tube, and the end cap 7 and the polymer material tube body 1 are sealed at this end of the tube body by methods including but not limited to hot melt connection, ultrasonic welding, bonding, etc. The other end of the square hollow tube is connected to a main joint 8 of the same material or metal material, and the main joint and the polymer material tube body 1 are connected by connection processes including but not limited to hot melt connection, ultrasonic welding, bonding, etc. The main joint 8 connects the fluid with the CDU / other pipelines through a connecting hose. A water diversion hole is processed on the side wall of the polymer material tube body 1 to serve as the above-mentioned installation through hole 11, and the water diversion hole and the water diversion joint assembly are connected by connection processes including but not limited to hot melt connection, ultrasonic welding, bonding, etc.

[0062] In some embodiments, Figure 4 , 5 As shown, the water diversion joint assembly includes an embedded nut and a polymer material adapter 2. The embedded nut is the above-mentioned metal adapter 3. The embedded nut is a metal part. In order to avoid electrochemical corrosion between dissimilar metals, it is preferred to use the same material as the quick-connect joint (a metal external joint 4); the polymer material adapter 2 uses the same material as the polymer material tube body 1 (PPE in this embodiment). The polymer material adapter 2 is designed as a stepped T-shaped structure. The T-shaped structure is connected to the inner wall of the water diversion hole and the outer wall of the tube body at two mutually perpendicular outer wall surfaces, which can achieve a more reliable connection. The embedded nut is embedded in the polymer material adapter by injection molding. The internal thread of the embedded nut matches the external thread of the male connector of the quick-connect joint for connection; the sealing ring of the quick-connect joint is pressed against the outer end face of the adapter by the quick-connect joint through a threaded connection.

[0063] In some embodiments, Figure 2 As shown, compared to Figure 4 Middle water tap assembly, Figure 2 The adapter assembly also uses injection molding to connect the polymer material adapter 1 with the embedded nut and then connect it to the pipe body. The difference is that the metal embedded nut is located on the inner side of the adapter. Figure 4 The water diverter joint assembly can achieve a longer thread connection length with the quick-connect joint, especially when the external thread length of the quick-connect joint is short, a more reliable thread connection can be achieved.

[0064] In some embodiments, Figure 4As shown, the tube body has a circular cross-section inner cavity, and the outer shape of the tube body is also arc-shaped on the sides except the water diversion hole side, which can have better pressure bearing capacity and can use less material than the square hollow tube under the same working pressure. On the other hand, the circular inner cavity has a smaller flow resistance than the square inner cavity; except for the above differences, the connection between the water diversion hole and the adapter assembly and the structure of the adapter assembly can be adopted Figure 2 , 4 The corresponding structure is that the adapter assembly is connected to the water diversion hole of the pipe body, and the embedded nut in the adapter assembly and the adapter are injection molded as a whole.
