Description

Technical Field

[0001] The utility model relates to the technical field of heat conduction, in particular to a heat dissipation water drain with a built-in filter. Background Art

[0002] With the rapid development of technologies such as mechanics, microelectronics, and computers, chips are playing an increasingly important role in our daily lives. Chips generate a large amount of heat during operation, and excessively high temperatures can affect their performance, necessitating heat dissipation.

[0003] Currently, mature heat dissipation methods include air cooling and liquid cooling. Chip liquid cooling radiators have the advantages of being quiet, stable in cooling, and having low dependence on the environment. Traditional liquid cooling radiators consist of three parts: a cold head, a radiator, and a fan. The cold head is in direct contact with the chip and is responsible for absorbing the heat emitted by the chip. The water pump in the cold head is responsible for providing the power for the coolant to flow. After the coolant absorbs heat in the cold head, it flows into the radiator through the water pipe under the action of the water pump. The radiator is installed in the chassis and is responsible for dissipating the heat absorbed by the coolant to the outside of the chassis. After cooling in the radiator, the coolant flows back to the cold head through the water pipe, thus circulating. The fan is installed on the radiator and is responsible for accelerating the air flow in the radiator and improving heat dissipation efficiency.

[0004] However, existing water-cooled radiators often suffer from the following issues: Due to factors such as the structure and materials of the heat sink within the water cooling head, prolonged operation of the water cooling radiator inevitably leads to the presence of suspended impurities in the coolant. Furthermore, due to the small cross-sectional area of ​​the coolant channel within the heat sink's fin structure, impurities easily accumulate there, reducing the overall heat dissipation efficiency of the water cooling radiator. Utility Model Content

[0005] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide a heat dissipation water drain with a built-in filter, which has the advantages of filtering impurities in the coolant, avoiding accumulation at the cold head and improving the heat dissipation efficiency.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a heat dissipation water radiator with a built-in filter, comprising:

[0007] The radiator body has multiple heat dissipation fin groups inside;

[0008] A first water chamber is provided on one side of the water drain body;

The coolant flowing into the second water chamber flows from the water pipe through the other side of the water drain body and flows back into the filter element of the first water chamber, and then flows through the cold head device and flows back into the first water chamber.

[0013] The present invention is further provided that the first water chamber includes: a partition arranged in the first water chamber, a first chamber located on one side of the partition, and a second chamber located on the other side of the partition and used to assemble the filter element.

[0016] The present invention is further provided with a plurality of filter holes on the bottom plate, the first side plate and the second side plate.

[0017] The present invention further provides that the aperture of the filter hole is smaller than or equal to the spacing between the heat absorbing fins in the cold head device.

DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0031] This embodiment relates to a heat sink with a built-in filter. Figure 1-Figure 3, including: a drain body 100, a first water chamber 200, a second water chamber 300, a water pipe 400 and a filter 210. Among them, a plurality of heat dissipation fin groups 110 are opened in the drain body 100, and the plurality of heat dissipation fin groups 110 are arranged at intervals to evenly absorb the heat in the coolant. The first water chamber 200 is arranged on one side of the drain body 100, and the second water chamber 300 is arranged on the other side of the drain body 100. The first water chamber 200 is connected to a cold head device (not shown), which is in contact with the heat-generating components. The coolant in the first water chamber 200 passes through the cold head device to cool the heat-generating components. The coolant flowing out of the cold head device absorbs heat and flows back into the first water chamber 200. The water pipe assembly 400 connects the first water chamber 200 and the second water chamber 300. The water pipe assembly 400 comprises multiple spaced-apart water pipes, allowing coolant to flow back and forth through the radiator body 100. The water pipe assembly 400, in conjunction with the heat sink fin assembly 110, absorbs heat from the heat-absorbing coolant, thereby converting the heat-absorbing coolant into coolant. The coolant then flows through the first water chamber 200 to the cold head device. A filter element 210 is assembled within the first water chamber 200 and is used to filter out impurities in the coolant to prevent it from flowing back into the cold head device and causing accumulation and clogging. Specifically, in this embodiment, the cross-sectional area of ​​the first water chamber 200 is much larger than the cross-sectional area of ​​the water channel assembly. Therefore, the flow rate of the coolant in the first water chamber 200 is much lower than the flow rate in the water channel. Impurities such as suspended matter carried by the coolant can be precipitated and filtered at the filter element 210 in the first water chamber 200. The filtered coolant then flows into the cold head device, reducing the impurity content in the liquid and preventing the accumulation of impurities. The coolant flowing into the first water chamber 200 thus flows from the water pipe fitting 400 through one side of the water drain body 100 and then into the second water chamber 300. The coolant flowing into the second water chamber 300 flows from the water pipe fitting 400 through the other side of the water drain body 100, flows back into the filter element 210 of the first water chamber 200, then flows through the cold head device and flows back into the first water chamber 200, thus forming a circulating cooling system. The coolant flows through the cold head device and then flows through the water pipe fitting 400, thereby removing the heat absorbed by the coolant through the heat dissipation fin assembly 110, timely and effectively cooling the heat-generating components and the coolant that has absorbed heat, and then flows back into the filter element 210, thereby filtering out impurities in the coolant, avoiding the accumulation of impurities in the cold head device, and improving the overall heat dissipation efficiency.

[0032] In this embodiment, referring to Figure 2The first water chamber 200 includes a partition 220, a first chamber 230, and a second chamber 240. The partition 220 is disposed within the first water chamber 200, with the first chamber 230 located on one side of the partition 220 and the second chamber 240 located on the other side of the partition 220 and used to assemble the filter element 210. Dividing the first water chamber 200 into two independent parts, namely the first chamber 230 and the second chamber 240, controls the flow direction of the coolant and allows the filtration process of the filter element 210 to proceed unaffected in the second chamber 240.

[0033] Furthermore, the first water chamber 200 also includes: a water inlet 250 connected to the first chamber 230 and a water outlet 260 connected to the second chamber 240 and corresponding to the filter element 210. Specifically, the water inlet 250 and the water outlet 260 are respectively connected to the cold head device through pipes. After the coolant flows through the cold head device, it flows into the first chamber 230 through the water inlet 250. The coolant in the first chamber 230 flows through the water drain body 100 and then flows back into the filter element 210 of the second chamber 240. The coolant then flows into the cooling device from the water outlet 260, thereby achieving circulating cooling, improving heat dissipation efficiency and filtering impurities.

[0034] In this embodiment, referring to Figure 4 The filter element 210 includes a base plate 211, a first side plate 212, a second side plate 213, and a support portion 214. The base plate 211 is positioned at the bottom of the second chamber 240, allowing the filter element 210 to be securely mounted within the second chamber 240. The first side plate 212 extends upward from one end of the base plate 211 and abuts the water pipe 400. The second side plate 213 extends upward from the other end of the base plate 211. The first and second side plates 212, 213 guide the flow of coolant, effectively intercepting impurities. The support portion 214 is connected to the ends of the first and second side plates 212, 213, respectively, away from the base plate 211, enhancing the overall structural stability of the filter element 210. Specifically, the first and second side plates 212, 213 extend vertically from the base plate 211, extending from front to back. The filter element 210 is U-shaped. In other embodiments, the filter element 210 may also have other shapes, such as a semicircular or square shape.

[0035] In this embodiment, a plurality of filter holes 215 are provided on the bottom plate 211 , the first side plate 212 and the second side plate 213 to intercept impurities in the coolant.

[0036] Further, refer to Figure 3The diameter of filter holes 215 is smaller than or equal to the spacing between the heat-absorbing fins (not shown) in the cold head assembly. Due to the small diameter, larger particles or other impurities are prevented from passing through these holes and are instead trapped on filter element 210, effectively preventing impurities from flowing into the cold head assembly and becoming lodged on the heat-absorbing fins. Furthermore, despite the small diameter, the large number of filter holes 215 ensures that the coolant can pass through these holes smoothly, maintaining unimpeded water flow.

[0037] In this embodiment, referring to Figure 3 A water pipe assembly 400 is disposed between the two heat dissipation fin groups 110. Specifically, the heat dissipation fin group 110 is disposed between the two water pipe members 400. Therefore, the heat dissipation fin group 110 and the water pipe members 400 are arranged in an interlaced manner and in close contact with each other, ensuring that the coolant can quickly transfer heat to the heat dissipation fin group 110 during the flow process, so that the coolant is evenly cooled. After the heat dissipation fin group 110 absorbs the heat from the water pipe members 400, it dissipates it into the air, improving the heat exchange efficiency and the heat dissipation effect. Usually, a fan is also installed on one side of the water row to better dissipate the heat into the air, further improving the heat dissipation effect.

[0038] In this embodiment, referring to Figure 3 A through hole 500 is provided on one side of the water pipe 400 connecting the first water chamber 200 and the second water chamber 300 to ensure that the coolant is evenly distributed when entering the water drain body 100, which helps to increase the contact area between the coolant and the heat dissipation fin group 110, thereby improving the heat exchange efficiency.

[0039] Furthermore, the through hole 500 and the water pipe fitting 400 are both in the shape of elongated strips, and the water pipe fitting 400 is inserted into the through hole 500. Compared with circular or other shaped holes, the elongated strip shape can reduce the resistance of the coolant flow, allowing the coolant to pass through the water drain body 100 more smoothly, thereby improving the overall efficiency.

[0040] In this embodiment, referring to Figure 1 Fixed plates 120 for connecting the first water chamber 200 and the second water chamber 300 are also provided on both sides of the water drain body 100 to enhance the connection strength between the water drain body 100 and the first water chamber 200 and the second water chamber 300 to prevent loosening during use.

[0041] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
