Description

Technical Field

[0001] This utility model relates to a pipe fitting, and more particularly to a coolant connection pipe for supplying coolant to a cooling circulation heat dissipation component, and a heat dissipation system having the coolant connection pipe. Background Technology

[0002] Existing large electronic devices, such as server units, dissipate heat through a liquid cooling exchange unit and a water tank. The liquid cooling exchange unit uses a pump to drive coolant through the server unit, allowing the coolant to absorb heat generated by the server's operation and then return to the liquid cooling exchange unit, where it exchanges heat with the water in the tank. In this way, the liquid cooling exchange unit can drive the coolant to circulate between the server unit and the liquid cooling exchange unit, and between the water tank and the liquid cooling exchange unit, thereby achieving the effect of cooling the server unit.

[0003] The aforementioned server unit, liquid cooling exchanger, pump, and water tank are connected by a coolant connection pipe to facilitate coolant transport. However, since these components are manufactured separately, their connection ports may not be able to form a coaxial connection. Furthermore, due to tolerances or slight dimensional changes in the server unit or liquid cooling exchanger caused by thermal expansion and contraction, the connection ports of these components may not be able to achieve coaxial alignment. This makes it difficult for the ends of the coolant connection pipe to form an accurate and tight connection with the connection ports of each component, potentially leading to leakage.

[0004] Therefore, the existing coolant connection pipes do indeed need to be improved. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a coolant connection pipe, the two ends of which can be accurately connected to heat dissipation components.

[0006] The directional terms or similar terms used throughout this utility model, such as "front", "back", "left", "right", "top", "bottom", "inner", "outer", "side", etc., are mainly for reference to the directions in the accompanying drawings. Each directional term or similar term is only used to assist in explaining and understanding the various embodiments of this utility model and is not intended to limit this utility model.

[0007] The use of the quantifiers “a” or “an” for the elements and components described throughout this utility model is merely for convenience and to provide the general meaning of the scope of this utility model; in this utility model, it should be interpreted as including one or at least one, and a single concept also includes multiple cases, unless it clearly means otherwise.

[0008] The terms "combination," "integration," or "assembly" used throughout this utility model mainly include those that allow for separation without damaging the components after connection, or those that make the components inseparable after connection. Those skilled in the art can choose the appropriate term based on the material of the components to be connected or the assembly requirements.

[0009] The coolant connection pipe of this utility model includes: a pipe body, with a connection portion at each of the opposite ends of the pipe body, and at least one annular rib on the inner wall surface of at least one connection portion of the pipe body; and a flexible section located between the two connection portions, the outer wall of the flexible section having several intersecting outer annular protrusions and several outer annular recesses, the inner wall of the flexible section having several intersecting inner annular protrusions and several inner annular recesses, the outer annular protrusions and the inner annular recesses being radially aligned, and the outer annular recesses and the inner annular protrusions being radially aligned.

[0010] Therefore, the coolant connecting pipe of this utility model has several intersecting outer ring protrusions and several outer ring recesses, as well as intersecting inner ring protrusions and several inner ring recesses in the flexible section of the pipe body. This allows the pipe body to have better flexibility for axial expansion and contraction and radial deformation, so that the two ends of the pipe body can be respectively connected to misaligned components. This compensates for the positional deviation between the two components caused by manufacturing tolerances or assembly position adjustments, thereby improving assembly convenience and preventing coolant leakage. In addition, when the coolant passes through at least one ring protrusion, it can increase the flow rate.

[0011] The axial length between the two ends of the tube body is less than or equal to 20 cm. This allows the tube body to be used for installation of two components in a narrow space.

[0012] The diameter of the pipe body is 40–80 mm. This allows the pipe body to have an appropriate diameter, which avoids excessive energy consumption when pushing coolant if the pipe diameter is too large, and also avoids insufficient coolant transfer if the pipe diameter is too small.

[0013] The diameter of the pipe body is 50-60 mm. This allows the pipe body to have an appropriate diameter, which avoids excessive energy consumption when pushing coolant if the pipe diameter is too large, and also avoids insufficient coolant transfer if the pipe diameter is too small.

[0014] The radial protrusion distance of the at least one annular rib on the inner wall surface of the connector is 1 to 3 mm. This prevents the at least one annular rib from protruding excessively from the inner wall surface of the connector, thus avoiding obstruction of coolant transport.

[0015] The at least one annular rib has an axial width of 2 to 6 mm. Thus, the at least one annular rib can have an appropriate axial width to improve the coolant flow rate.

[0016] The at least one annular rib has a narrower axial width than the inner annular protrusion. Thus, the at least one annular rib can have an appropriate axial width to improve the coolant flow rate.

[0017] The inner wall surface of at least one connecting portion of the pipe body has several annular ribs, which are spaced apart from each other on the inner wall surface of the connecting portion. In this way, the flow rate of the coolant can be further improved by using several annular ribs.

[0018] The distance between two adjacent annular ribs is greater than the axial width of the annular rib. Thus, the flow rate of the coolant can be further improved by using several annular ribs.

[0019] A cooling circulation system includes: a coolant module; a heat source; a pump that drives a coolant to circulate between the coolant module and the heat source; and a coolant connecting pipe connected between at least two of the coolant module, the heat source, and the pump to allow coolant flow. Thus, the pipe body can have better flexibility for axial expansion and contraction, as well as radial deformation, so that both ends of the pipe body can be respectively engaged with misaligned components, thereby compensating for positional deviations between the two components caused by manufacturing tolerances or assembly adjustments. This improves assembly convenience and prevents coolant leakage.

[0020] The heat source is a server array. Therefore, the cooling circulation system can effectively dissipate heat from the server array. Attached Figure Description

Detailed Implementation

[0023] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments of this utility model are described below in detail with reference to the accompanying drawings; in addition, those symbols that are marked with the same symbols in different drawings are considered to be the same and their descriptions will be omitted.

[0024] Please refer to Figure 1 , Figure 2As shown, this is a preferred embodiment of the coolant connection pipe T of the present invention. The coolant connection pipe T includes a pipe body 1, with a connecting portion 11 formed at each of the opposite ends of the pipe body 1. Each of the two connecting portions 11 has an opening 11a, allowing the pipe body 1 to be connected to, for example, the inlet of a pump or coolant tank through the two connecting portions 11, and allowing coolant to flow within the pipe body 1 through the two openings 11a. The pipe body 1 can be, for example, made of rubber, silicone, plastic, or a flexible metal. In this embodiment, the pipe body 1 has an axial direction O1, which is the direction passing through the opposite ends of the pipe body 1, and the axial direction O1 is preferably located at the geometric center of the cross-section of the pipe body 1. The axial length between the opposite ends of the pipe body 1 can be less than or equal to 20 cm, so that the pipe body 1 can be used for installation with a narrow distance between two components. Furthermore, the diameter of the pipe body 1 can be 40-80 mm, preferably 50-60 mm. Thus, the pipe body 1 can have an appropriate pipe diameter to avoid excessive energy consumption when pushing coolant due to an excessively large pipe diameter, and to avoid insufficient coolant transfer due to an excessively small pipe diameter.

[0025] The tube body 1 has a flexible section 12, which can be located between the two connecting portions 11, allowing the tube body 1 to have elasticity, such as extension, bending, or slight rotation, through the flexible section 12. Furthermore, an outer tube wall 121 of the flexible section 12 may have several outer annular protrusions 13 and several outer annular recesses 14, which are staggered along the axial direction of the tube body 1. An inner tube wall 122 of the flexible section 12 may have several inner annular protrusions 15 and several inner annular recesses 16, which are staggered along the axial direction of the tube body 1. Notably, the outer annular protrusions 13 and the inner annular recesses 16 are aligned radially O2 of the tube body 1, and the outer annular recesses 14 are radially aligned with the inner annular protrusions 15. Thus, the tube body 1 can have better flexibility in the axial direction to allow for axial expansion and contraction, and the tube body 1 is flexible in the radial direction, so that the tube body 1 can deform in the radial direction, so that the two ends of the tube body 1 can be respectively connected to misaligned components, thereby compensating for the positional deviation between the two components caused by manufacturing tolerances or assembly position adjustments.

[0026] Please continue reading. Figure 1 , Figure 2As shown, in this embodiment, at least one connecting portion 11 of the pipe body 1 may have an inner wall surface 11b, which may extend from the opening 11a to the flexible section 12. The inner wall surface 11b may have at least one annular rib 17, so that the inner diameter of the connecting portion 11 may be instantaneously reduced by the at least one annular rib 17. When the coolant passes through the at least one annular rib 17, it may have the effect of increasing the flow rate.

[0027] Furthermore, the radial protrusion distance H of the at least one annular rib 17 on the inner wall surface of the connecting portion 11 can be 1 to 3 mm, and the axial width W of the at least one annular rib 17 can be 2 to 6 mm. This prevents the at least one annular rib 17 from excessively protruding from the inner wall surface of the connecting portion 11, thus avoiding obstruction of coolant flow. Preferably, the inner wall surface of the at least one connecting portion 11 can have several annular ribs 17, each annular rib 17 being spaced apart from the inner wall surface of the connecting portion 11. The spacing between two adjacent annular ribs 17 can be the same, or the spacing between two adjacent annular ribs 17 can be different. The distance D between two adjacent annular ribs 17 can be greater than the width W. Preferably, the distance between the opening 11a of the connecting portion 11 and the nearest annular rib 17 can be at least 2 to 3 cm. This allows for further improvement of the coolant flow rate through several annular ribs 17.

[0028] Please refer to Figure 3 , Figure 4 As shown, the coolant connection pipe T can be used in a cooling circulation system S, which may have a pump P, a coolant module M, and a heat source E. The coolant connection pipe T can be connected between the pump P, the coolant module M, and the heat source E through the two connection parts 11. Furthermore, the pump P may have an outlet P1, and the pump P may have rotor blades or other structures to drive the coolant flow, as those skilled in the art will understand, and will not be elaborated here. The outlet P1 of the pump P can be connected to the heat source E through the coolant connection pipe T to deliver coolant to the heat source E. The heat source E may be, for example, a server array, and the heat source E may have cooling distribution units (CDUs) to deliver coolant to the server array, thereby absorbing the heat energy of the server array.

[0029] The heat source E can be connected to the coolant module M via a pipe U. Furthermore, the coolant module M can have a heat sink M1 and a storage device M2. The heat sink M1 can have existing heat dissipation devices such as a fan and a heat sink plate. The high-temperature coolant output from the heat source E can dissipate heat through the heat sink M1 to form a low-temperature coolant, which can then be fed into the storage device M2 via the pipe. In this embodiment, the storage device M2 can be connected to an inlet P2 of the pump P via a coolant connecting pipe T. This allows the low-temperature coolant to be driven by the pump P into the heat source E to absorb its heat. Alternatively, the coolant connecting pipe T can be connected between the heat source E and the coolant module M, or between the heat sink M1 and the storage device M2, to facilitate the transfer of coolant within the coolant module M.

[0030] In summary, the coolant connecting pipe of this utility model has several intersecting outer ring protrusions and several outer ring recesses, as well as intersecting inner ring protrusions and several inner ring recesses in the flexible section of the pipe body. This allows the pipe body to have better flexibility for axial expansion and contraction, as well as radial deformation. This allows the two ends of the pipe body to be respectively connected to misaligned components, thereby compensating for positional deviations between the two components caused by manufacturing tolerances or assembly position adjustments. This can improve assembly convenience and prevent coolant leakage. In addition, when the coolant passes through at least one ring protrusion, it can increase the flow rate.

Any modifications and alterations made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the technical scope protected by the present invention.
