Description

Technical Field

[0001] This utility model relates to a backflow prevention unit assembly, and more particularly to a backflow prevention unit assembly that connects the coolant flow path. Background Technology

[0002] Existing large electronic devices, such as server units, dissipate heat through a liquid cooling exchange device. This liquid cooling exchange device achieves its cooling effect by circulating coolant between the server unit and the liquid cooling exchange device, as well as between the water tank and the liquid cooling exchange device.

[0003] The aforementioned server unit and liquid cooling exchange device are connected by several coolant connection pipes to form a coolant supply. Each cooling pipe is typically connected to a flange structure at the connection point between two cooling pipes by a pipe clamp to form a liquid-tight connection. However, this pipe clamp is bulky and difficult to use for connecting cooling pipes located in confined spaces. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a non-return unit assembly that can be lightweight for connection to cooling pipes in confined spaces.

[0005] 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.

[0006] 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.

[0007] The terms “first,” “second,” … and “Nth” used throughout this utility model are mainly used to distinguish different elements or features (such as elements, directions, or steps), and do not indicate the maximum or minimum number of these elements or features possessed by a corresponding subject or method, nor do they limit the order of priority.

[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 anti-reverse unit assembly of this utility model includes: a first connector having a through hole, the first connector having a plurality of first clamping members located at the periphery of the first connector; a second connector having a through hole, the second connector having a plurality of second clamping members located at the periphery of the second connector, the plurality of first clamping members and the plurality of second clamping members being engaged with each other to connect the first connector and the second connector; and a valve member located between the first connector and the second connector, the valve member having a through hole that is aligned with the through hole of the first connector and the through hole of the second connector respectively.

[0010] Therefore, the anti-reverse unit assembly of this utility model has a plurality of first clamping members in the first connector and a plurality of second clamping members in the second connector. The first connector is connected to the second connector with the plurality of first clamping members and the plurality of second clamping members in the second connector, so that the first connector and the second connector can be joined by a simple structure to reduce the overall volume and achieve the effect of connecting pipes in narrow spaces.

[0011] The first end of the first connector has an annular groove, and the plurality of first clamping members can be displaced in the circumferential direction to engage with the annular groove. In this way, the plurality of first clamping members can adjust their position by circumferential displacement within the annular groove.

[0012] Each of the first clamping members has a first engaging portion and a first fastening portion. The first engaging portion abuts against the circumferential surface of the first connecting member to mate with the second connecting member, and the first fastening portion abuts against the annular groove via an abutting protrusion. In this way, each of the first clamping members can be fastened to the annular groove by the first fastening portion.

[0013] In this design, an annular protrusion abuts against the annular groove, and the first clamping member has an arc-shaped groove with a corresponding curvature to the annular groove. When the abutting protrusion engages with the annular groove, the annular protrusion engages with the arc-shaped groove. In this way, the first clamping member can smoothly move within the annular groove.

[0014] The first end of the second connector has an annular groove, and the plurality of second clamping members can be displaced in the circumferential direction to engage with the annular groove. In this way, the plurality of second clamping members can adjust their position by circumferential displacement within the annular groove.

[0015] Each of the second clamping members has a second engaging portion and a second fastening portion. The second engaging portion abuts against the circumferential surface of the second connecting member to mate with the first connecting member, and the second fastening portion abuts against the annular groove via an abutting protrusion. In this way, each of the second clamping members can be fastened to the annular groove by the second fastening portion.

[0016] In this design, an annular protrusion abuts against the annular groove, and the second clamping member has an arc-shaped groove with a corresponding curvature to the annular groove. When the abutting protrusion engages with the annular groove, the annular protrusion engages with the arc-shaped groove. In this way, the second clamping member can smoothly move within the annular groove.

[0017] The plurality of first clamping members are integrally formed with the first connector and protrude radially from the circumferential surface of the first connector. This further simplifies the structure of the first connector.

[0018] The total axial thickness of the first clamping member, the second clamping member, and the valve member combined is 200-240 mm. This allows for a smaller total axial thickness, making it suitable for use in confined spaces.

[0019] The valve has a one-way flap, the center of which is concentric with the center of the through hole. Thus, when the coolant pushes the one-way flap, the force on the flap is evenly distributed, making it easier to open and reducing the fluid pushing pressure.

[0020] The one-way flap is located in the through hole and can be opened and closed. Thus, the one-way flap can open when the coolant flows in a predetermined direction and close when the coolant flows in the opposite direction.

[0021] The valve has a sealing ring on each of its two surfaces, which are respectively abutted against by the first connector and the second connector. This effectively prevents coolant leakage. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please refer to Figure 1 As shown, this is the first embodiment of the anti-reverse unit assembly T of the present invention, which includes a first connector 1, a second connector 2 and a valve 3. The first connector 1 and the second connector 2 are engaged with each other, and the valve 3 is located between the first connector 1 and the second connector 2. The first connector 1 and the second connector 2 clamp the valve 3.

[0026] Specifically, the first connector 1 has a first end 1a and a second end 1b opposite to each other. The first end 1a can be connected to a cooling pipe, which can be used to transport coolant. The first connector 1 has a through hole 11 that penetrates the first end 1a and the second end 1b, allowing coolant to flow through the through hole 11. The first connector 1 may have a plurality of first clamping members 12, which can be spaced apart around the periphery of the first connector 1. For example, there can be four first clamping members 12, which can be symmetrically distributed around the periphery of the first connector 1.

[0027] In this embodiment, the first connector 1 can be a circular ring. The first end 1a of the first connector 1 can have an annular groove 13, which is circular and surrounds the through hole 11, with the center of the groove 13 being the geometric center of the through hole 11. The plurality of first clamping members 12 are displaceably engaged with the annular groove 13. Furthermore, each first clamping member 12 can have a first engaging portion 121 and a first fastening portion 122. The first engaging portion 121 abuts against the circumferential surface of the first connector 1 and is used to mate with the second connector 2 (described in detail later). The first fastening portion 122 abuts against the annular groove 13 via an abutting protrusion 122a.

[0028] More specifically, an annular protrusion 13a can be formed between the annular groove 13 and the outer peripheral wall of the first connector 1. For example, the annular groove 13 forms a recess on the first end face 1a, which can naturally form the annular protrusion 13a with the outer peripheral wall of the first connector 1. One side of the annular protrusion 13a can be adjacent to the annular groove 13, and the other side of the annular protrusion 13a can be the outer peripheral wall of the first connector 1.

[0029] The first clamping member 12 may have an arc-shaped groove 14 between its abutting protrusion 122a and the first engaging portion 121. This arc-shaped groove 14 may have a curvature corresponding to the circular outline of the annular groove 13. When the abutting protrusion 122a engages with the annular groove 13, the annular protrusion 13a engages with the arc-shaped groove 14, thereby allowing the first clamping member 12 to be held in place by the annular groove 13. In this way, the plurality of first clamping members 12 can be displaced circumferentially within the annular groove 13.

[0030] The second connector 2 can be engaged with the first connector 1. Specifically, the second connector 2 has a first end 2a and a second end 2b, the first end 2a being used to connect to another cooling pipe, and the second end 2b being oriented towards the first connector 1. The second connector 2 has a through hole 21 that extends through the first end 2a and the second end 2b, allowing coolant to flow through the through hole 21. Therefore, the engagement of the first connector 1 and the second connector 2 allows coolant to flow between the two cooling pipes.

[0031] The second connector 2 may have a plurality of second clamping members 22, which may be distributed at intervals around the periphery of the second connector 2. The plurality of second clamping members 22 of the second connector 2 may be positioned opposite to the plurality of first clamping members 11 of the first connector 1.

[0032] Furthermore, the first end 2a of the second connector 2 may have an annular groove 23, which may be a circular annular groove. The annular groove 23 may surround the through hole 21, such that the center of the annular groove 23 is the geometric center of the through hole 21. An annular protrusion 23a may be formed between the annular groove 23 and the outer peripheral wall of the second connector 2.

[0033] The plurality of second clamping members 22 can be coupled to the annular groove 23, thereby allowing the plurality of second clamping members 22 to be displaced circumferentially within the annular groove 23. Furthermore, each second clamping member 22 may have a second engaging portion 221 and a second fastening portion 222. The second engaging portion 221 abuts against the periphery of the second connecting member 2 and is used to mate with the first engaging portion 121 of the first connecting member 1. The second fastening portion 222 abuts against the annular groove 23 via an abutting protrusion 222a.

[0034] The abutting protrusion 222a of the second clamping member 22 and the second engaging part 221 may have an arc-shaped groove 24. The arc-shaped groove 24 may have a curvature corresponding to the circular outline of the annular groove 23. When the abutting protrusion 222a engages with the annular groove 23, the annular protrusion 23a can engage with the arc-shaped groove 24, thereby allowing the second clamping member 22 to be fastened to the annular groove 23.

[0035] Therefore, the positions of the plurality of second clamping members 22 and the plurality of first clamping members 12 can be adjusted by circumferential displacement in the annular groove 23 and the annular groove 13, thereby enabling the plurality of second clamping members 22 and the plurality of first clamping members 12 to be accurately aligned at a predetermined position.

[0036] More specifically, the second connecting portion 221 of the second clamping member 22 and the first connecting portion 121 of the first clamping member 12 can be detachably connected by means of snap-fit ​​or screw-fit. In this embodiment, the second connecting portion 221 and the first connecting portion 121 may each have a screw hole R1, which respectively penetrates the second connecting portion 221 and the first connecting portion 121. The two screw holes R1 extend axially and are aligned, and are respectively screwed into the two screw holes R1 by a screw R2, so that the first clamping member 12 and the second clamping member 22 can connect the first connecting member 1 and the second connecting member 2. In this embodiment, the total axial thickness H of the first connecting portion 121 and the second connecting portion 221 after being combined with the valve member 3 can be 200-240 mm.

[0037] The valve 3 can be located between the first connecting member 1 and the second connecting member 2. The valve 3 can have a through hole 31, which is aligned with the through hole 11 of the first connecting member 1 and the through hole 21 of the second connecting member 2, allowing coolant to flow between the first connecting member 1 and the second connecting member 2 through the through hole 31. Furthermore, the valve 3 can have a one-way flap 32, which is closable within the through hole 31. The one-way flap 32 can be pivotally connected to the valve 3 to shield the through hole 31. For example, the one-way flap 32 can be pivotally connected above the through hole 31, and the one-way flap 32 can naturally droop downwards under gravity to shield the through hole 31. Preferably, the one-way flap 32 can be a circular flap, with its center concentric with the center of the through hole 31. In this way, when the coolant pushes the one-way flap 32 through the through hole 31, the one-way flap 32 can be subjected to uniform force, which makes the one-way flap 32 easy to open and reduces the fluid pushing pressure.

[0038] In this embodiment, the valve member 3 may have two opposing surfaces 3a, which face the first connector 1 and the second connector 2 respectively. Each surface 3a may have a sealing ring 33, which can be abutted by the first connector 1 and the second connector 2 to form a liquid-tight connection. One surface 3a may have a groove 3b, with a through hole 31 penetrating the bottom of the groove 3b. The one-way flap 32 can be pivotally connected to one surface 3a of the valve member 3 and accommodated in the groove 3b. The radial dimension of the one-way flap 32 may be larger than the diameter of the through hole 31. The one-way flap 32 can abut against the bottom of the groove 3b, thereby forming a pivoting motion in a single direction. Thus, the valve member 3 can control the flow direction of the coolant to form a check valve. For example, the valve member 3 allows the one-way flap 32 to open when the coolant flows in a predetermined direction and close when the coolant flows in the opposite direction.

[0039] Please refer to Figure 3 , Figure 4 As shown, this is a second embodiment of the anti-reverse unit assembly of this utility model. Compared with the first embodiment, in this embodiment, the first connector 1 has several first clamping members 15, which are integrally formed with the first connector and protrude radially from the circumferential surface of the first connector 1. Each first clamping member 15 may have a screw hole R1, which can be used to align with the screw holes R1 of the second clamping member 22 of the first connector 2, so as to form a screw engagement through the screw R2. Therefore, the structure of the first connector 1 can be further simplified.

[0040] In summary, the anti-reverse unit assembly of this utility model has a plurality of first clamping members in the first connector and a plurality of second clamping members in the second connector. The first connector is connected to the second connector by the plurality of first clamping members and the plurality of second clamping members, so that the first connector and the second connector can be joined by a simple structure to reduce the overall volume and achieve the effect of connecting pipes in narrow spaces.
