Description

A joint for reducing the setting height of the rotating head

This creation is about the joint of the radiator, and especially about a joint that can reduce the height of the rotating head.

The water-cooled radiator is an efficient heat exchange element that can quickly remove the waste heat generated by the electronic components, effectively reduce the temperature of the electronic components, and increase the stability and life of the electronic components. It has been widely used in high-efficiency electronic components.

The core of the water cooling system is to use a liquid cooling fluid as the heat exchange medium. The liquid cooling fluid has high thermal conductivity, allowing the cooling fluid to flow directly into a water-cooled radiator through a joint and directly contact the heat sink fins. With the temperature equalizing plate, the cooling fluid can quickly take away heat, and let the cooling fluid flow out through another joint to an external heat sink to quickly cool down, and the cooling fluid after cooling will flow into the water-cooled radiator again Inside and form a circulating heat dissipation system.

Therefore, the water-cooling system needs to install a circulating pipeline to import and export the cooling fluid, and in order to meet the needs of the use of small spaces, the joint needs to use the Taiwan Patent No. 109214564 "Rotary Joint for Water-Cooled Radiator". The joint can rotate freely to meet the installation requirements of different piping methods.

For the joint described in the aforementioned patent, in order to allow the rotating head to be rotatable to join the pipe body and avoid water leakage, the contact surface between the pipe body and the rotating head must be provided with a coupling element and a water blocking element. The coupling element generally uses a C-shaped buckle. To buckle the pipe body and the rotating head to avoid the separation of the pipe body and the rotating head, and the water blocking element usually uses washers or O-rings, etc., to avoid water leakage between the pipe body and the rotating head. However, in order to install the coupling element and the water blocking element, the pipe body of the joint must be lengthened to provide the coupling element and the water blocking element, which will cause the installation height of the rotating head to be too high and cannot meet the installation requirements in a small space.

The main purpose of this creation is to expose a joint that reduces the installation height of the rotating head, which requires installation in a small space.

To achieve the above objective, this creation discloses a joint for reducing the height of the rotating head, which includes a pipe body, a rotating head, and a water blocking element, wherein the pipe body has an inner pipe and a plurality of fluid passages that are connected laterally to the inner pipe. Mouth and an outer ring surface. The rotary head has a groove and a fluid pipe, the groove covers the outer ring surface so that the rotary head can rotate relative to the pipe body, and the fluid pipe is connected to the plurality of fluid passages, and the groove and There is a contact surface between the outer ring surfaces. The water blocking element is arranged on the contact surface to form a water blocking structure between the pipe body and the rotating head to avoid water leakage.

According to this, the design in this creation allows the rotating head to rotate relative to the pipe body through the groove covering the outer ring surface, so that the contact surface on which the water blocking element is provided overlaps the wall thickness of the fluid pipe, which can reduce The overall height of the tube body further reduces the installation height of the rotating head and meets the installation requirements in a narrow space.

The detailed description and technical content of this creation are described as follows in conjunction with the diagrams:

Please refer to "Figure 1" and "Figure 2". This creation is a joint that reduces the height of the rotating head. It includes a pipe body 10, a rotating head 20, a water blocking element 30 and a C-shaped buckle 40 , Wherein the pipe body 10 has an inner pipe 11, a plurality of fluid penetration ports 12 that are transversely connected to the inner pipe 11 and an outer ring surface 13. The rotating head 20 has a groove 21 and a fluid pipe 22. The groove 21 covers the outer ring surface 13 so that the rotating head 20 can rotate relative to the pipe body 10 and allows the fluid pipe 22 to communicate with the plurality of fluids. The through hole 12 has a contact surface 50 between the groove 21 and the outer ring surface 13. The water blocking element 30 is disposed on the contact surface 50 to form a water blocking structure between the pipe body 10 and the rotating head 20, and the C-shaped buckle 40 is also disposed on the contact surface 50 and buckles the pipe. The body 10 and the rotating head 20 avoid separation of the tube body 10 and the rotating head 20. Wherein, the water blocking element 30 is, for example, a gasket or O-ring.

In one embodiment, the tube body 10 has a caulking portion 14 on the side away from the rotating head 20, and the tube body 10 has a groove 15 in the region adjacent to the caulking portion 14, and the groove 15 surrounds The tube body 10 is provided. In addition, a leak-proof element 60 may be arranged in the groove 15. In an embodiment, the leak-proof element 60 may be embedded in the groove 15 by injection molding to increase the leak-proof effect and avoid the problem of falling off. In addition, the leak-proof element 60 has a pressure contact edge 61 (as shown in FIG. 2) protruding outside the groove 15. For example, the diameter of the leak-proof element 60 is greater than the depth of the groove 15, so When the leak-proof element 60 is inserted into the groove 15, a part of the leak-proof element 60 (that is, the pressing edge 61) will protrude out of the groove 15.

In addition, the rotating head 20 can extend a connecting portion 23 in a direction perpendicular to the axial direction of the pipe body 10, and allow the fluid pipe 22 to be located in the connecting portion 23. In addition, the connecting portion 23 can be provided with at least one non-returning flange 231, and the at least one non-returning flange 231 can be connected to a hose (not shown), because the at least one non-returning flange 231 will form an inner large and an outer small Therefore, when the hose is inserted into the at least one anti-retraction flange 231, it has the effect of anti-retraction and anti-detachment.

Please refer to "FIG. 2" and "FIG. 3" together. The rotating head 20 of the present invention can be used to install on an opening 71 of a cavity 70 of a water-cooled radiator. The caulking portion 14 of the tube body 10 is inserted into the opening 71 in a tight fitting manner to form a first-layer sealing structure. In addition, the pressure contact edge 61 of the leak-stop element 60 will closely contact the cavity 70 to form a water-stop structure surrounding the opening 71 to form a second layer of sealing structure.

As mentioned above, the advantages of this creation compared with the conventional ones include at least:

1. The design that the outer ring surface is covered by the groove so that the rotating head can rotate relative to the pipe body, so that the contact surface on which the water blocking element is provided overlaps the wall thickness of the fluid pipe, which can reduce the pipe body The required height, thereby reducing the installation height of the rotating head, meets the installation requirements of a small space.

2. The caulking portion of the tube body is inserted into the opening in a tight fitting manner to form a first layer of sealing structure, and the pressure contact edge of the leak-stop element closely contacts the cavity to form a second layer of sealing structure, so that the The cooling fluid in the cavity will not leak out and the rotating head will not be loose.

3. The rotating head can rotate relative to the pipe body and has the characteristics of free rotation, which can meet the installation requirements of different piping methods.
