Description

Technical Field

[0001] The present invention relates to a water cooling device for computer equipment, in particular to a water cooling head for CPU and GPU. Background Art

[0002] With the development of technology, the computing power of various computer devices (such as CPU, GPU) is getting stronger and stronger, and it is also more and more prone to heat. Therefore, various cooling devices are needed to assist in heat dissipation. A common cooling device is the water cooling system.

[0003] The water cooling system includes a water cooling head, a water tank and a pipeline. The water cooling head is used to be close to the computer equipment to be cooled, and the pipeline connects the water cooling head and the water tank, allowing the coolant to circulate between the water tank and the water cooling head to remove the heat of the computer equipment.

[0004] In order to form a flow channel inside the water cooling head for the water cooling liquid to flow, the water cooling head usually includes two base bodies connected to each other, at least one of the two base bodies is formed with a channel-shaped groove on a side facing the other base body, so that when the two base bodies are connected, a flow channel for the water cooling liquid to flow is sandwiched.

[0005] However, the disadvantage of the above structure is that although the two bodies are tightly connected by screw locking, it is still possible that the water-cooling liquid will flow out of the gap between the two bodies due to plastic molding tolerance, insufficient screw locking pressure, excessive locking pressure during installation causing cracks in the threads, long-term operation at high temperatures causing plastic thermal deformation and gaps, etc. Once it flows out, it may drip onto the computer equipment to be cooled and cause serious damage. In addition, the computer equipment will not react immediately when it touches the water-cooling liquid. It is often discovered that the water leaks a large amount of water-cooling liquid and causes the system to short-circuit and burn. In particular, computer equipment that uses a water-cooling heat dissipation system is often a very high-priced model, so it is even more necessary to avoid damage. Summary of the invention

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a water leakage detection water cooling head, which can remind the user when the water cooling liquid is about to flow out, so that the user can repair or replace it as soon as possible to avoid water cooling liquid leakage.

[0007] In order to achieve the above-mentioned purpose of the invention, the technical means adopted by the present invention is to design a water leakage detection water cooling head, which includes:

[0008] A first seat body having a first outer annular surface, a first joint surface and a first outer edge, wherein the first outer edge is an edge where the first outer annular surface and the first joint surface meet;

[0009] A second body having a second outer ring surface, a second joint surface and a second outer edge, the second outer edge being the edge at the junction of the second outer ring surface and the second joint surface; the first body and the second body are combined with each other, and the first joint surface and the second joint surface face each other, and at least one water-cooling liquid flow channel is formed between the first body and the second body;

[0010] A water-sensitive color-changing sticker attached to the first body or the second body and arranged along the first outer edge or the second outer edge; the water-sensitive color-changing sticker changes color when it comes into contact with liquid.

[0011] The advantage of the present invention is that by attaching water-sensitive color-changing stickers to the two bodies and arranging the water-sensitive color-changing stickers along the first outer edge or the second outer edge, when the water-cooling liquid in the two bodies gradually seeps out and comes into contact with the water-sensitive color-changing stickers, the user can perceive that the water-cooling head may be about to leak through the color change of the water-sensitive color-changing stickers, so that the water-cooling head can be repaired or replaced as soon as possible, and the present invention thereby achieves the purpose of preventing the water-cooling liquid from leaking out and damaging computer equipment.

[0012] Furthermore, in the water leakage detection water-cooling head, the water-sensitive color-changing sticker is attached to the first outer ring surface of the first body and the second outer ring surface of the second body and covers the first outer edge and the second outer edge.

[0013] Furthermore, in the water leakage detection water-cooling head, the water-sensitive color-changing sticker is formed in a circular shape and at least completely covers the first outer edge of the first body.

[0014] Furthermore, in the water leakage detection water-cooling head, the contours and positions of the first outer edge of the first body and the second outer edge of the second body are the same.

[0015] Furthermore, in the water leakage detection water-cooling head, the second outer edge of the second body is larger than the first outer edge of the first body, and at least one sticker groove is formed on the second joint surface of the second body, the position of the sticker groove corresponding to the first outer edge of the first body, the water-sensitive color-changing sticker extending into the sticker groove and covering the edge at the junction of the sticker groove and the second joint surface and the first outer edge.

[0016] Furthermore, in the water leakage detection water-cooling head, the number of the at least one sticker groove of the second body is two and they are arranged in parallel at intervals.

[0017] Furthermore, the leak-detection water-cooling head further includes a flow-channel deflecting member that connects the first housing and the second housing. The flow-channel deflecting member has a flow channel that is connected to and in communication with the at least one water-cooling liquid channel. The water-sensitive color-changing sticker extends to the communication portion between the flow channel and the at least one water-cooling liquid channel.

[0018] Furthermore, in the leak-detection water-cooling head, the water-sensitive color-changing sticker is attached between the first joint surface of the first housing and the second joint surface of the second housing.

[0019] Furthermore, in the leak-detection water-cooling head, the water-sensitive color-changing sticker is laterally exposed between the first housing and the second housing.

[0020] Furthermore, in the leak-detection water-cooling head, a color-changing groove is recessed in either the first joint surface of the first housing or the second joint surface of the second housing, and the water-sensitive color-changing sticker is received in the color-changing groove.

[0021] Furthermore, the leak-detection water-cooling head further includes a waterproof gasket that is disposed between the first joint surface of the first housing and the second joint surface of the second housing and is located outside the at least one water-cooling liquid channel.

[0022] Furthermore, in the leak-detection water-cooling head, a gasket groove is recessed in either the first joint surface of the first housing or the second joint surface of the second housing, and the waterproof gasket is received in the gasket groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The following further elaborates on the technical means adopted by the present invention to achieve the intended invention purpose in conjunction with the accompanying drawings and the preferred embodiments of the present invention.

[0053] Please refer to Figures 1 to 3As shown, the first embodiment of the water leakage detection water cooling head of the present invention includes a first housing 10, a second housing 20, and a water-sensitive color-changing sticker 30, and preferably has a waterproof gasket 40.

[0054] Please refer to Figures 2 to 4 As shown, the aforementioned first housing 10 has a first outer ring surface 11, a first joint surface 12, and a first outer edge 13. The first outer edge 13 is the edge at the junction of the first outer ring surface 11 and the first joint surface 12.

[0055] The aforementioned second housing 20 has a second outer ring surface 21, a second joint surface 22, and a second outer edge 23. The second outer edge 23 is the edge at the junction of the second outer ring surface 21 and the second joint surface 22. The first housing 10 and the second housing 20 are combined with each other. When combined, the first joint surface 12 and the second joint surface 22 face each other and are preferably in close contact with each other. Preferably, the first housing 10 is used to abut against the computer device to be cooled, or in other words, the first housing 10 is closer to the computer device to be cooled than the second housing 20, but this is not limited thereto.

[0056] In the first embodiment, both the first housing 10 and the second housing 20 are rectangular, and the contours and positions of the first outer edge 13 of the first housing 10 and the second outer edge 23 of the second housing 20 are the same, but this is not limited thereto.

[0057] The first housing 10 and the second housing 20 sandwich at least one water cooling liquid flow channel 14, 24. Preferably, the water cooling liquid flow channels 14, 24 are recessed on the first joint surface 12 and the second joint surface 22, that is, the first joint surface 12 and the second joint surface 22 are respectively provided with grooves or channels to jointly form the water cooling liquid flow channels 14, 24, but this is not limited thereto.

[0058] The aforementioned waterproof gasket 40 is sandwiched between the first joint surface 12 of the first housing 10 and the second joint surface 22 of the second housing 20, and is located outside all the water cooling liquid flow channels 14, 24, thereby avoiding the outward flow of the water cooling liquid in the water cooling liquid flow channels 14, 24. Preferably, a gasket groove 15 is recessed on the first joint surface 12 of the first housing 10, and the waterproof gasket 40 is accommodated in the gasket groove 15, but this is not limited thereto. The gasket groove 15 can also be formed on the second joint surface 22 of the second housing 20, or there may be no gasket groove 15 at all.

[0059] The aforementioned water-sensitive color-changing sticker 30 is attached to the first housing 10 and / or the second housing 20, and is arranged along the first outer edge 13 and / or the second outer edge 23. In the first embodiment, the water-sensitive color-changing sticker 30 is attached to the first outer ring surface 11 of the first housing 10 and the second outer ring surface 21 of the second housing 20, and covers the first outer edge 13 and the second outer edge 23 (such as Figure 4As shown. Preferably, the water-sensitive color-changing sticker 30 is wound into a circular shape and at least completely covers the first outer edge 13 of the first housing 10. In the first embodiment, the water-sensitive color-changing sticker 30 completely covers the first outer edge 13 of the first housing 10 and the second outer edge 23 of the second housing 20. Thus, in addition to being able to detect water leakage in all directions, the water-sensitive color-changing sticker 30 wound into a complete circle also has a certain water leakage prevention effect to some extent. However, the setting of the water-sensitive color-changing sticker 30 is not limited to this. For example, the water-sensitive color-changing sticker 30 can also only cover a part of the length of the first outer edge 13 and the second outer edge 23. For instance, the water-sensitive color-changing sticker 30 can be divided into four sections and respectively cover the middle parts of the four sides of the rectangular first outer edge 13 and the second outer edge 23, and this is also acceptable.

[0060] When the water-sensitive color-changing sticker 30 comes into contact with a liquid, it will change color, and whether it is in contact with ordinary water or special water-cooling liquid, it will cause the water-sensitive color-changing sticker 30 to change color. In addition, it is preferable that the water-sensitive color-changing sticker 30 changes to another color, but it can also change to transparent, as long as it can be noticed by the user. In this embodiment, the water-sensitive color-changing sticker 30 is formed by spraying an ink that becomes transparent when exposed to water on a paper or gummed plane with an adhesive. The ink and the sticker are of different colors, with the ink on top and the paper below. When the ink encounters moisture, it becomes transparent, revealing the color of the underlying sticker. However, the type and principle of the water-sensitive color-changing sticker 30 are not limited to this.

[0061] The present invention mainly uses the water-sensitive color-changing sticker 30 that changes color (or becomes transparent) when exposed to water, which is wound and attached around the joints of the CPU / GPU or other open water-cooling products (such as between the first outer edge 13 of the first housing 10 and the second outer edge 23 of the second housing 20) for visual reminder. So that when the user is in daily use or when detecting water leakage after just installing the open water-cooling circuit, they can immediately and accurately observe the position of water leakage through the color-changing water-sensitive color-changing sticker 30, and then can immediately shut down or perform repairs to avoid greater damage caused by a large amount of water-cooling liquid leaking out through the motor push.

[0062] The present invention thereby increases the safety of the open water-cooling system and can provide an immediate and accurate water leakage detection function. Moreover, the water-sensitive color-changing sticker 30 does not require power consumption and can be replaced, and can also maintain the detection function after repair. Finally, the user can immediately perform the shutdown operation after observing, avoiding greater damage caused by the system short-circuiting when exposed to water in the powered state. The present invention thereby achieves the invention purposes of detecting water leakage, improving safety, and being convenient to use.

[0063] The foregoing first embodiment is mainly used for the CPU, and the subsequent second embodiment is mainly used for the GPU. Please refer to Figures 5 to 7As shown, the second embodiment is substantially the same as the foregoing first embodiment, except that the second housing 20 of the second embodiment is larger than the first housing 10. Therefore, the second outer edge 23 is larger than the first outer edge 13. Specifically, the width of the second housing 20 is the same as the width of the first housing 10, but the length of the second housing 20 is greater than the length of the first housing 10. Therefore, both ends of the second housing 20 protrude from the first housing 10, but not limited thereto. Only one end of the second housing 20 may protrude from the first housing 10.

[0064] Please refer to Figure 6 、 Figure 7 and Figure 9 As shown, in addition, at least one sticker groove 25 is formed on the second joint surface 22 of the second housing 20. The position of the sticker groove 25 corresponds to the first outer edge 13 of the first housing 10. Thus, the water-sensitive color-changing sticker 30 can extend into the sticker groove 25. In this way, the edge where the sticker groove 25 meets the second joint surface 22 and the first outer edge 13 can still be covered. In other words, even if the second housing 20 is longer or larger, it is still possible to detect whether there is water leakage at that place, and the water-sensitive color-changing sticker 30 can still surround a complete circle.

[0065] In the case where both ends of the second housing 20 protrude from the first housing 10, the number of sticker grooves 25 on the second housing 20 is two, and they are arranged in parallel at intervals and respectively correspond to the opposite sides of the first outer edge 13 of the first housing 10. However, in the case where only one end of the second housing 20 protrudes from the first housing 10, the number of sticker grooves 25 on the second housing 20 only needs to be one.

[0066] In addition, please refer to Figure 7 and Figure 8 As shown, the second embodiment further has a flow turning member 50, which connects the first housing 10 and the second housing 20 and preferably abuts against the first outer ring surface 11 and the second outer ring surface 21. The flow turning member 50 has a flow turning channel 51, and the flow turning channel 51 is connected and communicated with the water-cooling liquid channels 14 and 24. Thus, the flow turning member 50 can change the direction of the pipeline connecting the present invention to the outside. The water-sensitive color-changing sticker 30 extends to the connection between the flow turning channel 51 and the water-cooling liquid channels 14 and 24. The water-sensitive color-changing sticker 30 can completely cover the periphery of the connection or can only be located at a part of the periphery of the connection.

[0067] In summary, in the case where the second housing 20 is larger than the first housing 10 in the second embodiment, the invention purposes of detecting water leakage, improving safety and being convenient to use can still be achieved.

[0068] Please refer to Figure 10 and Figure 11As shown, the third embodiment (CPU) of the present invention is substantially the same as the first embodiment (CPU), except that the water-sensitive color-changing sticker 30 of the third embodiment is attached between the first joint surface 12 of the first housing 10 and the second joint surface 22 of the second housing 20, and preferably adjacent to the first outer edge 13 and / or the second outer edge 23. Preferably, the water-sensitive color-changing sticker 30 is laterally exposed between the first housing 10 and the second housing 20, that is, the water-sensitive color-changing sticker 30 can be seen from the lateral direction, whereby the color change of the water-sensitive color-changing sticker 30 can be seen. However, this is not a limitation. The first housing 10 or the second housing 20 can also be made transparent. In this way, even if the water-sensitive color-changing sticker 30 is not laterally exposed, its color change can still be observed, and the same invention purpose as the first embodiment can be achieved in the same way.

[0069] Preferably, a color-changing groove 16 is recessed on the first joint surface 12 (or the second joint surface 22 of the second housing 20) of the first housing 10, and the water-sensitive color-changing sticker 30 is accommodated in the color-changing groove 16. Preferably, the color-changing groove 16 extends to the first outer edge 13, so that the water-sensitive color-changing sticker 30 can be seen from the lateral direction. However, there may also be no color-changing groove 16, but let the water-sensitive color-changing sticker 30 extend to the first outer edge 13. In this way, the purpose of laterally exposing the water-sensitive color-changing sticker 30 between the first housing 10 and the second housing 20 can be achieved.

[0070] Please refer to Figure 12 and Figure 13 As shown, the fourth embodiment (GPU) of the present invention is substantially the same as the second embodiment (GPU), except that the water-sensitive color-changing sticker 30 of the fourth embodiment is attached between the first joint surface 12 of the first housing 10 and the second joint surface 22 of the second housing 20. The remaining details of the fourth embodiment are the same as those of the third embodiment where the water-sensitive color-changing sticker 30 is also attached between the first joint surface 12 and the second joint surface 22, so they will not be repeated here.

[0071] The above are only the preferred embodiments of the present invention, and do not impose any formal restrictions on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
