Description

Technical Field

[0001] The utility model relates to a water cooling structure, in particular to a water cooling head structure capable of improving heat exchange efficiency. Background Art

[0002] Traditional liquid cooling systems primarily consist of multiple pipes connected in series with a water-cooling block, a pump, or a cooling module (such as a radiator). The water-cooling block often comes into contact with the heat-generating component to dissipate heat.

[0003] Conventional water-cooling heads have a heat exchange chamber for a working fluid to pass through, and are equipped with a plurality of fins for heat dissipation. The fins absorb heat generated by the heating element, and the working fluid flowing through the heat exchange chamber exchanges heat with the fins, ultimately removing the heat to achieve the purpose of heat dissipation. Specifically, conventional water-cooling heads include at least an upper cover and a lower shell, which together define the heat exchange chamber. The fins are arranged in the heat exchange chamber to increase the heat dissipation area, and the fins form channels for the working fluid between each pair. In this case, an inlet and an outlet of the conventional water-cooling head are respectively arranged on the side of the upper cover or the lower shell to allow the working fluid to flow into or out of the heat exchange chamber.

[0004] However, due to the single-layer flow path design of the heat exchange chamber, after the working fluid enters the heat exchange chamber of a conventional water-cooled head through the inlet, most of the working fluid flows only through the upper surface of the chamber, surrounded by the plurality of fins, and then quickly flows out, without effectively convection with the higher-temperature fluid in the lower layer of the heat exchange chamber (e.g., in the channels between the plurality of fins). Alternatively, due to a lack of guidance, some of the working fluid may flow turbulently within the heat exchange chamber, causing heat accumulation. Consequently, conventional water-cooled heads exhibit poor heat exchange efficiency.

[0005] Therefore, how to solve the above problems and deficiencies is the direction that the creators of this case and related manufacturers engaged in this industry are eager to study and improve. Utility Model Content

[0006] The main purpose of the present invention is to provide a water-cooling head structure that can solve the above-mentioned problems, so that the working fluid can have a unidirectional flow path in the vertical depth and horizontal direction inside the water-cooling head structure, so that the working fluid can pass through each part completely, thereby increasing the contact area and contact time to fully carry out heat exchange, thereby significantly improving the overall heat exchange efficiency.

[0007] Therefore, the present invention provides a water cooling head structure, characterized by comprising:

[0008] An upper cover having a first opening and a second opening that pass through the upper and lower sides and are separated from each other;

[0009] a middle partition, the upper side of which is provided with the upper cover, and a first passage and a second passage penetrating the middle partition corresponding to the first opening and the second opening, respectively;

[0010] A radiator is assembled on the lower side of the middle partition, and the radiator and the middle partition jointly seal and define a heat exchange chamber connected to the first channel and the second channel, wherein the radiator has a heat dissipation side corresponding to the middle partition and a heat absorption side opposite thereto, and a plurality of plates arranged laterally at intervals are protruded from the heat dissipation side into the heat exchange chamber, and a plurality of transverse flow channels are formed between the plates, and the plurality of transverse flow channels correspond to the first channel above in an alternating manner to form a first exchange zone, and a second exchange zone is formed at both ends, and the second exchange zone is connected to a peripheral flow channel at the outer edge of the plurality of plates, and the peripheral flow channel corresponds to the second channel above.

[0011] In this way, a working fluid flows into one of the first opening or the second opening and flows through the corresponding first channel or the second channel through the middle partition into the heat exchange chamber. Due to the continuous pressure, the working fluid is pushed through the multiple transverse flow channels, then rises into the other of the first channel or the second channel, and finally flows out from the other of the first or second openings of the upper cover that is different from the working fluid inflow, thereby completing a one-way fluid flow path, and vice versa.

[0012] The water cooling head structure, wherein: the lower side of the upper cover is also recessed with a longitudinal guide channel connected to the first opening, the longitudinal guide channel is correspondingly connected to the first channel of the middle partition, the first channel is formed to extend longitudinally, and the flow channel width of the longitudinal guide channel is greater than the channel width of the first channel.

[0013] The water cooling head structure, wherein: the lower side of the upper cover is further recessed with a peripheral guide channel connected to the second opening, the peripheral guide channel is correspondingly connected to the second channel of the middle partition, and the flow channel width of the peripheral guide channel is greater than the channel width of the second channel.

[0014] The water-cooling head structure, wherein: the peripheral guide channel has two drainage sections located on both sides of the longitudinal guide channel and a confluence section that is transversely connected to the multiple drainage sections and connected to the second opening.

[0015] The water-cooling head structure described above, wherein: the two second channels of the middle partition are respectively arranged on both sides of the first channel, and respectively correspond to the drainage sections of the peripheral guide channel of the upper cover, and respectively correspond to the two ends of the multiple transverse flow channels connected to the peripheral flow channel in the heat exchange chamber.

[0016] The water cooling head structure is characterized in that: a limiting groove is further recessed on the upper side of the middle partition, and the lower side of the upper cover is embedded in the limiting groove for assembly.

[0017] The water-cooling head structure, wherein: the lower side of the middle partition is further provided with an outer wall, and the outer wall is used to seal together with the radiator to define the heat exchange chamber.

[0018] The present invention utilizes the flow path design of the water-cooling head structure to allow the working fluid to flow from one of the first opening or the second opening to the other in a unidirectional flow path, entering the heat exchange chamber through the middle partition, and using stable pressure to push the working fluid between the multiple plates to continuously and completely pass through every part between the plates. This can increase the contact area and contact time of heat exchange, fully and completely carry out heat exchange, thereby significantly improving the overall heat dissipation efficiency and avoiding the occurrence of heat accumulation.

DETAILED DESCRIPTION

[0026] The above-mentioned objectives and structural and functional characteristics of the present invention will be described with reference to the preferred embodiments shown in the accompanying drawings.

[0027] Please refer to the attached figure. Figure 1 This is a schematic diagram of the combined state of the utility model; Figure 2This is a schematic diagram of the decomposed state of the utility model; Figure 3 This is a schematic diagram of the decomposed state of the utility model; Figure 4 This is a perspective diagram of the assembled state of the utility model; Figure 5 is a schematic top view of the working fluid flow of the present invention; and, Figure 6 This is a schematic diagram of another embodiment of the present invention in an exploded state.

[0028] Please also see Figures 1 to 3 The present invention provides a water-cooling head structure 1, comprising: an upper cover 10, a middle partition 20 and a radiator 30, which are stacked and assembled in sequence from top to bottom, so that the heat absorbed by the radiator 30 from the heat source (not shown) below can be fully and completely heat exchanged and removed through multiple layers of flow paths with three-dimensional dimensions and depth.

[0029] like Figure 2 and Figure 3 As shown, the upper cover 10 has a first opening 12 and a second opening 14 that pass through the upper and lower sides and are separated from each other, and the two are formed independently and separated from each other in the structure of the upper cover 10. The first opening 12 and the second opening 14 on the upper side of the upper cover 10 can be respectively connected to a joint or pipe (not shown) for supplying or recovering the working fluid, but not limited to this. It is worth noting that the first opening 12 and the second opening 14 can be used as the inlet or outlet of the working fluid as required, and the flow directions of the two are opposite, and vice versa. And according to the design of the above-mentioned guide channel configuration, the utility model can guide the working fluid to advance in a one-way manner along the expected flow direction (inlet and outlet).

[0030] And, as Figure 3 As shown, a peripheral guide channel 141 communicating with the second opening 14 may be further recessed on the underside of the upper cover 10. The peripheral guide channel 141 provides a space for the working fluid to accumulate before being discharged or flowing into the water-cooling head structure 1 of the present invention. Specifically, the peripheral guide channel 141 is recessed substantially around the underside of the upper cover 10.

[0031] Please combine Figure 2 and Figure 3 As shown, the lower side of the upper cover 10 is assembled to the upper side of the middle partition 20 (i.e., the upper cover 10 is assembled to the upper side of the middle partition 20). For example, a retaining groove 20a can be recessed on the upper side of the middle partition 20, and the upper cover 10 can be inserted into the retaining groove 20a to complete the assembly, but this is not limited to this. In addition, the middle partition 20 has a first channel 21 and a second channel 22 that pass through the middle partition 20 to its lower side, corresponding to the first opening 12 and the second opening 14, respectively.

[0032] For example, the first channel 21 can be formed on the upper cover 10 at the first opening 12 of the middle diaphragm 20. Therefore, if the working fluid enters through the first opening 12, it will be guided downward through the first channel 21 under pressure. Conversely, the working fluid heading toward the second opening 14 will be forced upward into the second channel 22 (or through the peripheral guide channel 141) under the opposite pressure and then discharged from the second opening 14. In other words, the working fluid flows in opposite directions through the middle diaphragm 20.

[0033] In addition, Figure 6 As shown, the lower side of the upper cover 10 may also be further recessed with a longitudinal guide channel 121 (for example, located on a long central axis of the upper cover 10 and extending linearly along the lower side of the upper cover 10) that communicates with the first opening 12. It is worth noting that because the corresponding flow paths have opposite directions, the longitudinal guide channel 121 is separated and independent from the peripheral guide channel 141 and is correspondingly communicated with the first channel 21 of the middle partition 20. For example, the first channel 21 is formed to extend longitudinally, and the longitudinal guide channel 121 may also have a flow channel width greater than the channel width of the first channel 21.

[0034] In addition, in this embodiment, the peripheral guide channel 141 can be connected to the second channel 22 of the middle partition 20, or it can be not provided. The peripheral guide channel 141 can be formed by two diversion sections 141a and a confluence section 141b. Among them, the multiple diversion sections 141a are respectively located on the left and right sides of the longitudinal guide channel 121, separated and independent from it and distributed roughly in parallel, and the confluence section 141b is laterally connected to the multiple diversion sections 141a and connected to the second opening 14, and finally guides the working fluid to be discharged from the second opening 14, but is not limited to this. Similarly, the flow channel width of the peripheral guide channel 141 can also be greater than the channel width of the second channel 22.

[0035] Thus, the present invention can control the working fluid to stably advance along the expected flow direction by allowing the working fluid to pass through the first channel 21 and the second channel 22 with different channel widths (inlet and outlet) through the middle partition plate 20 .

[0036] Fu Ru Figure 4 As shown, the radiator 30 is mounted on the lower side of the middle partition 20, so that the working fluid flows downward into a heat exchange chamber 40 which is sealed and defined by the two and connects the first channel 21 and the second channel 22. Figure 2 and Figure 3As shown, the lower side of the middle partition plate 20 may further include an outer wall 24 for sealing and defining the heat exchange chamber 40 with the heat sink 30, but the present invention is not limited thereto. For example, in another embodiment, the heat sink 30 having an outer wall (not shown) may be embedded in an embedding groove (not shown) on the lower side of the middle partition plate 20.

[0037] In the heat exchange chamber 40 , the working fluid exchanges heat with the heat sink 30 , removing heat absorbed by the heat sink 30 from the heat source (e.g., electronic components). Specifically, as described above, if the working fluid is configured to enter through the first channel 21 , it will be pushed by pressure to complete a one-way circulation, ultimately leaving the heat exchange chamber 40 through the second channel 22 (or, alternatively, the working fluid may flow in the opposite direction, entering through the second channel 22 and leaving the heat exchange chamber 40 through the first channel 21).

[0038] The radiator 30 has a heat-dissipating side 34 corresponding to the middle partition 20 and a heat-absorbing side 32 opposite thereto. For example, in actual use, a heat source can be placed in close proximity to the heat-absorbing side 32 below the radiator 30, allowing heat to be absorbed by the radiator 30 and transferred to the heat-dissipating side 34. Furthermore, the radiator 30 has a plurality of fins 36 protruding from the heat-dissipating side 34 into the heat exchange chamber 40 and arranged transversely and spaced apart for heat exchange. This forms a plurality of transverse flow channels 361 between the fins 36. Therefore, for example, when the working fluid flows downward from the first channel 21 into the heat exchange chamber 40 (depending on the flow direction, it may also enter from the second channel 22), its flow direction is guided by the plurality of transverse flow channels 361.

[0039] In detail, Figure 2 As shown, the middle position of the plurality of transverse flow channels 361 corresponds to the first channel 21 above in an interlaced manner, for example, they can be roughly vertically crossed to form a first exchange area at the intersection position and a second exchange area at both ends of the transverse flow channel 361.

[0040] For example, if the working fluid enters from the first channel 21, it will first be discharged vertically under pressure, from the first exchange zone at the center of the plurality of transverse flow channels 361 downward into the lower layer of the plurality of transverse flow channels 361, and then be divided from the center of the plurality of transverse flow channels 361 to the two ends and completely contact all the surfaces of the plate 36 for heat exchange, while forcing the heat-absorbing and high-temperature working fluid in the plurality of transverse flow channels 361 to circulate in one direction. In addition, the second exchange zone corresponds to a peripheral flow channel 362 formed by connecting to the outer edge of the plurality of plates 36, and the peripheral flow channel 362 corresponds to the at least one second channel 22 above. At this time, because the working fluid is continuously pushed by the continuous pressure from the first exchange zone, it will leave the second exchange zone at both ends of the plurality of transverse flow channels 361 and be pushed to the connected peripheral flow channel 362, corresponding to the second channel 22 respectively, and then be pushed upward into the second channel 22 for reflux.

[0041] Similarly, the present invention can also use the second opening 14 as an inlet for the working fluid. In this way, the working fluid will complete a one-way path circulation in the opposite fluid flow path described above and finally flow out of the first opening 12, but it can also continue to be pushed by sufficient pressure and achieve complete heat exchange. In this way, the present invention can achieve a complete one-way path, not only avoiding flow confusion and incomplete exchange of the working fluid, but also increasing the contact area and contact time. In particular, by vertically arranging the upper cover 10, the middle partition 20 and the radiator 30, the working fluid is continuously subjected to sufficient pressure and leaks from above to promote the circulation of the working fluid between the multiple sheets 36, effectively improving the circulation efficiency and avoiding heat accumulation.

[0042] More specifically, if Figure 6 As shown, if the longitudinal guide channel 121 extends linearly along the long central axis, the middle partition 20 may specifically include two second channels 22, which may be arranged on either side of the first channel 21 and parallel thereto. Furthermore, the guide sections 141a are arranged parallel to the longitudinal guide channel 121, corresponding to the peripheral guide channel 141 of the upper cover 10, and corresponding to the connection points of the peripheral flow channel 362 in the heat exchange chamber 40 with the outflow areas on either side of the plurality of transverse flow channels 361, thereby guiding the working fluid to circulate vertically upwards or downwards in a unidirectional path.

[0043] It is noteworthy that, when passing through the diffuser 30, the entire working fluid of the present invention will flow in a unidirectional direction through each surface of the plurality of heat exchange fins 36, thereby increasing the contact area and contact time, and fully exchanging heat with each surface without generating inefficient turbulence. Moreover, the plurality of heat exchange fins 36 simultaneously achieve the multiple purposes of promoting heat exchange, working fluid circulation efficiency, and unidirectional flow guidance.

[0044] As mentioned above, please refer to Figure 5 As shown, the water-cooling head structure 1 of the present invention allows the working fluid to flow in a predetermined unidirectional manner. For example, the working fluid flows from the first opening 12 through the middle baffle 20 into the heat exchange chamber 40, enters the plurality of transverse flow channels 361 through the first exchange zone within the heat exchange chamber 40, then exits through the second exchange zones at both ends of the plurality of transverse flow channels 361 to the peripheral flow channels 362, and is then continuously pushed by pressure through the corresponding second channels 22 on both sides, finally converging there and connecting to the second opening 14 for discharge. (Conversely, the working fluid can also flow from the second opening 14, but the flow direction is opposite to that described above). In this way, the present invention not only allows the working fluid to enter the heat exchange chamber 40 for heat exchange in a single regular direction, but also continuously provides a stable pressure for the working fluid with a vertical setting, so that the working fluid can enter the lower layer and completely contact every part of the heat exchange plate 36 of the radiator 30, thereby promoting the circulation of the working fluid therein, increasing the contact area and contact time, and fully performing heat exchange to remove heat, thereby effectively improving the overall heat exchange efficiency and avoiding the occurrence of heat accumulation.

[0045] The above description of the present invention is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent variations and modifications based on the present invention are also within the scope of the present invention.
