Description

Technical Field

[0001] The present disclosure generally relates to the field of water cooling device technology. More specifically, the present disclosure relates to a water cooling plate. Background Art

[0002] With the development of electronic technology, the performance of electronic equipment has improved rapidly, and the power dissipation of the entire system has also increased dramatically. The increase in power dissipation and the requirement for miniaturization have caused the problem of heat dissipation to become increasingly prominent. If this problem cannot be solved well, it will not only affect the performance of the equipment, but also shorten the life of the equipment. Studies have shown that among the various factors that affect the reliability of electronic devices, heat dissipation is crucial.

[0003] The heat generated by high-power semiconductor devices will cause the temperature of the chip to rise. If there are no appropriate heat dissipation measures, the temperature of the chip may exceed the maximum allowable temperature, resulting in the deterioration of device performance and even damage. Existing radiators are usually divided into air-cooled heat dissipation systems and water-cooled heat dissipation systems. The water-cooled heat dissipation system consists of a water-cooled plate, a water pipe and a water pump. The water-cooled plate has a water inlet and a water outlet. The water inlet and the water outlet form a circulating water circuit through a water pipe and a water pump. However, during use, the inlet of the water-cooled plate is susceptible to various adverse effects such as corrosion, cavitation, impurity impact, water flow impact, etc., which causes the water inlet to be damaged earlier than other parts, affecting the service life of the entire water-cooled plate.

[0004] In view of this, there is an urgent need to provide a water-cooling plate with an anti-corrosion component arranged at the position of the water inlet, so as to prevent the water inlet of the water-cooling plate from being corroded and extend the service life of the water-cooling plate. Utility Model Content

[0005] In order to at least solve one or more of the technical problems mentioned above, the present disclosure proposes a water cooling plate in multiple aspects. This solution can extend the service life of the water cooling plate by arranging an anti-corrosion component at the position of the water inlet.

[0006] In a first aspect, the present disclosure provides a water-cooled plate, comprising: a water channel for water flow to pass through, which is arranged inside the water-cooled plate, wherein a water inlet is provided at one end of the water channel and a water outlet is provided at the other end; and an anti-corrosion component is provided at the end wall position where the water flow impacts the water inlet.

[0007] In some embodiments, the anti-corrosion component is a pad fixed at the end wall of the water inlet and has a certain hardness.

[0008] In some embodiments, the projection of the water inlet in the water inlet direction is a circle with a diameter slightly larger than the width of the waterway, and the pad is a circular stainless steel structure slightly smaller than the water inlet.

[0009] In some embodiments, a water inlet assembly is also provided at the water inlet of the water cooling plate; the water inlet assembly includes an interconnected water inlet structure and a clamping structure; the water inlet structure is connected to a water inlet pipe, and the clamping structure is inserted into the water inlet and fixedly abutted against the pad.

[0010] In some embodiments, the water inlet structure is a circular ring structure with a certain extension length along the water inlet direction, and the middle area is a water flow channel; the clamping structure includes a first extension part and a second extension part, one end of which is connected to the extension end of the water inlet structure, and the other end continues to extend along the water flow direction; the inner side walls of the first extension part and the second extension part are relatively arranged curved surface structures, and the positive projections of the inner side walls of the first extension part and the second extension part in the water flow direction form a circle; wherein, the extension length of the first extension part is longer than the extension length of the second extension part, and the first extension part is welded and fixed to the pad.

[0011] In some embodiments, the water inlet structure is coplanar with the inner side wall of the compression structure, and the side wall thickness of the water flow channel at the compression structure position is smaller than the side wall thickness at the water inlet structure.

[0012] In some embodiments, a rectangular first anti-mis-installation structure perpendicular to the end wall of the water inlet structure is provided on the outer side wall of the second extension portion.

[0013] In some embodiments, the water-cooling plate includes a water-cooling plate body and a cover plate; a water channel for water to flow through is milled on the outer surface of the water-cooling plate body, the cover plate is covered on the water channel, and the cover plate and the water-cooling plate body are welded together; wherein the cover plate is provided with welding holes at the positions of the two ends along the extension direction of the water channel.

[0014] In some embodiments, the cover plate is provided with a through hole for the water inlet assembly to pass through at a position corresponding to the water inlet, and the through hole has a second anti-misinstallation structure that cooperates with the first anti-misinstallation structure on the side wall facing the water flow direction; wherein the thickness of the cover plate is equal to the height of the second extension portion.

[0015] In some embodiments, the anti-corrosion component is an anti-corrosion coating coated on the end wall where the water flow impacts the water inlet.

[0016] Through the water-cooled plate provided as above, the disclosed embodiment can prevent the water inlet from being corroded by providing an anti-corrosion component at the end wall position where the water flow impacts the water inlet, thereby extending the service life of the water-cooled plate. Furthermore, in some embodiments, by providing the anti-corrosion component as a circular stainless steel structure, since the stainless steel structure has the characteristics of wear resistance and rust resistance, the corrosion resistance and impact resistance at the inlet can be enhanced, thereby further extending the service life of the water-cooled plate.

As a result, the water inlet assembly not only has the function of inletting water, but also has the function of fixing the anti-corrosion component, and has a wide range of uses.

[0030] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0031] Exemplary application scenarios

[0032] like Figure 1-2 As shown, the present disclosure provides a water-cooled plate 1, which includes: a water channel 2 for water flow to pass through, which is arranged inside the water-cooled plate, wherein a water inlet 3 is provided at one end of the water channel 2 and a water outlet is provided at the other end; and an anti-corrosion component, which is provided at the end wall position where the water flow impacts the water inlet 3.

[0033] The solution disclosed in the present invention can prevent the water inlet 3 from being corroded by air, water flow, etc. by providing an anti-corrosion component at the end wall position where the water flow impacts the water inlet 3, thereby extending the service life of the water cooling plate 1.

[0034] Example 1

[0035] In view of this, an embodiment of the present disclosure provides a water cooling plate.

[0036] like Figure 1As shown, this embodiment provides a water-cooled plate 1, which includes: a water channel 2 for water flow to pass through, which is arranged inside the water-cooled plate, wherein a water inlet 3 is provided at one end of the water channel 2 and a water outlet is provided at the other end; and an anti-corrosion component, which is provided at the end wall position where the water flow impacts the water inlet 3.

[0037] In the scheme of this embodiment, the water-cooled plate 1 is a plate-like structure with a certain thickness, and the interior of the water-cooled plate 1 has a water channel 2 for water flow to pass through, which is arranged in a winding manner. Among them, the water channel 2 has two ends, one end has a water inlet 3, and the other end has a water outlet. The water inlet 3 of the water channel 2 is connected to the water inlet pipeline, and the water outlet is connected to the water outlet pipeline. When in use, the water flows into the water channel 2 from the water inlet 3 below the water-cooled plate 1, then passes through the water channel 2 on the water-cooled plate 1, and finally flows out from the water outlet above the water-cooled plate 1. Since the water flows into the water channel 2 vertically from the water inlet 3 of the water-cooled plate 1 during water intake, the position of the water inlet 3 will be impacted and corroded by the water flow, so an anti-corrosion component is provided at the end wall position where the water flow impacts the water inlet 3, so as to prevent the water inlet 3 from being corroded by air, water flow, etc., thereby extending the service life of the water-cooled plate 1.

[0038] In a specific scheme of this embodiment, the water-cooling plate 1 includes a water-cooling plate body 101 and a cover plate 102; a water channel 2 for water flow is milled on the outer surface of the water-cooling plate body 101, the cover plate 102 is covered on the water channel 2, and the cover plate 102 and the water-cooling plate body 101 are welded together; wherein the cover plate 102 is provided with welding holes at the positions of the two ends along the extension direction of the water channel 2.

[0039] In the above scheme, the water-cooled plate 1 includes a water-cooled plate body 101 and a cover plate 102. The water-cooled plate body 101 is provided with a water channel 2, and the water channel 2 is covered with a cover plate 102, so that the water channel 2 forms a cavity structure with a middle seal. Among them, the water channel 2 starts from the water inlet 3 at the lower left of the water-cooled plate 1 and then extends to the right side of the water-cooled plate 1, bends to the left at its extended end, and then bends again at its extended end to extend to the right side of the water-cooled plate 1, and is repeatedly distributed on the entire water-cooled plate 1. This arrangement increases the path of the water flow on the water-cooled plate 1, and the cooling effect is better.

[0040] The specific process of making the water channel 2 on the water-cooling plate 1 of this embodiment is to first mill a curved and extended water channel 2 for water flow on the outer surface of the water-cooling plate body 101, then cover the water channel 2 with a cover plate 102 made corresponding to the size of the water channel 2, and finally weld the cover plate 102 and the water-cooling plate body 101 together. For the aesthetics of welding, welding holes are provided at the positions of the two ends of the cover plate 102 along the left and right extending direction of the water channel 2, and the cover plate 102 and the water-cooling plate body 101 are welded together through the welding holes.

[0041] In other solutions of this embodiment, the cover plate 102 on the water-cooling plate 1 may also be in other forms. For example, the cover plate 102 may also be a structure formed by cutting materials according to the position of the water channel 2 and covering the entire water channel 2 .

[0042] In a specific implementation of this embodiment, the anti-corrosion component is a pad 4 fixed at the end wall of the water inlet 3 and having a certain hardness.

[0043] In the above scheme, the anti-corrosion component is a backing plate 4 with a certain hardness fixed at the end wall position of the water inlet 3. Since the backing plate 4 has a certain hardness, it can prevent deformation caused by water flow impact. In order to prevent the backing plate 4 from being corroded, an anti-corrosion layer can also be coated on the surface of the cover plate 102. Of course, the backing plate 4 can also be set as a replaceable component. Once the backing plate 4 is corroded or deformed, the backing plate 4 can be replaced without affecting the use of the water-cooled plate 1.

[0044] In a preferred solution of this embodiment, the projection of the water inlet 3 in the water inlet direction is a circle with a diameter slightly larger than the width of the waterway 2 , and the pad 4 is a circular stainless steel structure slightly smaller than the water inlet 3 .

[0045] In the above scheme, the water inlet 3 of the water-cooled plate 1 is a cylindrical structure along the water inlet direction, the opening and end wall of the water inlet 3 are both circular structures, and the pad 4 is a circular stainless steel structure slightly smaller than the water inlet 3. Among them, the depth of the water inlet 3 on the water-cooled plate body 101 is the same as the depth of the water channel 2, and the diameter of the opening of the water inlet 3 is slightly larger than the width of the water channel 2. The stainless steel pad 4 is inserted into the end wall position at the bottom of the water inlet 3 through the opening of the water inlet 3 for fixing. Correspondingly, a circular through hole is also provided at the position corresponding to the water inlet 3 on the cover plate 102 for water to enter the water channel 2. In the scheme provided in this embodiment, since the stainless steel structure has a certain hardness and is corrosion-resistant, the water inlet 3 can be prevented from being corroded, thereby extending the life of the water-cooled plate 1.

[0046] In another specific implementation of this embodiment, the anti-corrosion component is an anti-corrosion coating applied to the end wall position where the water flow impacts the water inlet 3. In this solution, the anti-corrosion component is not a circular stainless steel gasket, but is directly coated with an anti-corrosion coating at the end wall position at the bottom of the water inlet 3, thereby also preventing water and air from corroding the water inlet 3. This solution is simple to operate and can also save costs.

[0047] In a specific embodiment, a water inlet assembly 5 is also provided at the water inlet 3 of the water cooling plate 1; the water inlet assembly 5 includes an interconnected water inlet structure 501 and a clamping structure 502; the water inlet structure 501 is connected to the water inlet pipe, and the clamping structure 502 is inserted into the water inlet 3 and fixedly abutted against the pad 4.

[0048] Specifically, the water inlet structure 501 is a circular ring structure with a certain extension length along the water inlet direction, and the middle area is a water flow channel; the clamping structure 502 includes a first extension part 5021 and a second extension part 5022, one end of which is connected to the extension end of the water inlet structure 501, and the other end continues to extend along the water flow direction; the inner side walls of the first extension part 5021 and the second extension part 5022 are relatively arranged curved surface structures, and the positive projection of the inner side walls of the first extension part 5021 and the second extension part 5022 in the water flow direction forms a circle; wherein, the extension length of the first extension part 5021 is longer than the extension length of the second extension part 5022, and the first extension part 5021 is welded and fixed to the pad 4.

[0049] The water inlet structure 501 and the inner side wall of the pressing structure 502 are arranged coplanarly, and the side wall thickness of the water flow channel at the position of the pressing structure 502 is smaller than the side wall thickness at the water inlet structure 501 .

[0050] like Figure 1 As shown, a water inlet assembly 5 is also provided at the water inlet 3 at the lower left of the water cooling plate 1, and a water outlet assembly 6 is also provided at the water outlet at the upper left of the water cooling plate 1. When in use, the water inlet assembly 5 is connected to the water inlet pipe, and the water outlet assembly 6 is connected to the water outlet pipe. Water flows from the water inlet pipe through the water inlet assembly 5 into the water channel 2, flows through the water channel 2, and flows into the water outlet pipe from the water outlet assembly 6, and finally flows out of the water cooling plate 1.

[0051] like Figure 2As shown, in this specific scheme, the water inlet assembly 5 includes an interconnected water inlet structure 501 and a clamping structure 502. The water inlet structure 501 is a circular ring structure with a certain extension length along the water inlet direction, and the middle area is a water flow channel. One end thereof is connected to the water inlet pipe, and the other end is connected to the clamping structure 502. The clamping structure 502 includes a first extension portion 5021 and a second extension portion 5022 extending along the water flow direction. The side walls of the first extension portion 5021 and the second extension portion 5022 are curved structures that are arranged oppositely and have a certain thickness, the side wall thickness of the water inlet structure 501 is greater than the side wall thickness of the clamping structure 502, and the inner side wall of the water inlet structure 501 is arranged coplanar with the inner side wall of the clamping structure 502. The orthographic projection of the inner side wall of the first extension part 5021 in the water flow direction is an arc structure, and the orthographic projection of the inner side wall of the second extension part 5022 in the water flow direction is also an arc structure, and the two arc structures can form a circle. In other words, the first extension part 5021 and the second extension part 5022 of the compression structure 502 also constitute a water flow channel for water flow to pass through, and the water flow channel is interconnected with the water flow channel of the water inlet structure 501 and has the same diameter.

[0052] More specifically, the extension length of the first extension part 5021 of the clamping structure 502 is longer than the extension length of the second extension part 5022. When in use, the clamping structure 502 is inserted into the water inlet 3 through the through hole on the cover plate 102. Among them, taking the accompanying drawings as an example for explanation, the first extension part 5021 is installed near the left side of the water inlet 3, and the second extension part 5022 is installed near the right side of the water inlet 3. Since the first extension part 5021 is relatively long, the end of the first extension part 5021 extending into the water inlet 3 abuts against the anti-corrosion component, and the two are fixed by welding. Since the second extension part 5022 is relatively short, it is inserted into the water inlet 3 and will not block the flow of water in the waterway 2.

[0053] In a more specific embodiment, a rectangular first anti-mis-installation structure 50221 is provided on the outer side wall of the second extension portion 5022 and is perpendicular to the end wall of the water inlet structure 501 .

[0054] The cover plate 102 is provided with a through hole for the water inlet assembly 5 to pass through at a position corresponding to the water inlet 3, and the through hole has a second anti-misinstallation structure 1021 on the side wall facing the water flow direction, which cooperates with the first anti-misinstallation structure 50221; wherein the thickness of the cover plate 102 is equal to the height of the second extension portion 5022.

[0055] In the scheme of this embodiment, in order to prevent the installation of the water inlet assembly 5 and the water inlet 3 from being wrong, a first anti-mis-installation structure 50221 is provided at the outer side wall of the second extension portion 5022. The first anti-mis-installation structure 50221 is a rectangular structure provided perpendicular to the end wall of the water inlet structure 501. Since the water inlet structure 501 is a hollow annular structure, the end wall of the water inlet structure 501 refers to the side wall at the water inlet hole and the side wall at the water outlet hole of the water inlet structure 501. Since the water inlet assembly 5 first enters the water inlet 3 on the water cooling plate body 101 through the through hole provided on the cover plate 102, a second anti-mis-installation structure 1021 cooperating with the first anti-mis-installation structure 50221 is provided on the side wall of the through hole facing the flow direction of the water in the waterway. Among them, the second anti-mis-installation structure 1021 is a rectangular structure provided symmetrically with the first anti-mis-installation structure 50221. During installation, when the compression structure 502 of the water inlet assembly 5 is inserted into the water inlet 3, the first anti-mis-installation structure 50221 abuts against the second anti-mis-installation structure 1021, thereby ensuring that the extended end of the first extension part 5021 abuts against the anti-corrosion component. In this solution, since the thickness of the cover plate 102 is equal to the height of the second extension part 5022, the second extension part 5022 will not be inserted into the water inlet 3 in the water cooling plate body 101, thereby preventing the second extension part 5022 from blocking the fluidity of the water flow in the water channel 2.

[0056] The solution provided in this embodiment, on the one hand, is to prevent the water inlet 3 from being corroded by providing a stainless steel pad 4 at the end of the water inlet 3, thereby improving the service life of the water cooling plate 1. On the other hand, by improving the structure of the water inlet assembly 5, the stainless steel pad 4 is installed on the end wall of the water inlet 3 by using the water inlet assembly 5, and no additional installation components are required, thereby saving costs.
