Description

Technical Field

[0001] This invention relates to a heat dissipation component, and more particularly to a heat dissipation component that utilizes liquid heat conduction. Background Technology

[0002] Modern computer users prioritize high-performance computing, which necessitates higher power consumption from advanced components. Under high-speed operation, these components experience increased temperatures, impacting system smoothness. Liquid cooling systems are a common solution, absorbing heat from heat sources (such as the motherboard, CPU, or graphics chip) and then expelling the cooled liquid for further heat exchange, repeating this cycle to dissipate heat.

[0003] Furthermore, the temperature of heat sources (such as motherboards, CPUs, or display chips) is generally affected by the amount of liquid flow; the higher the flow rate, the better the heat dissipation capacity. Existing water-cooling heat dissipation components are usually limited by the space constraints of the heat source, so there are often situations where the flow channels are of varying widths. When the liquid flows from a wider channel to a narrower channel, a problem of greater flow resistance occurs, which in turn affects the heat dissipation efficiency of the heat dissipation components. Summary of the Invention

[0004] The present invention provides a heat dissipation component that can guide liquid flow to reduce the probability of the liquid not flowing smoothly due to excessive flow resistance.

[0005] The heat dissipation assembly of the present invention includes a housing and a partition structure. The housing has a chamber. The partition structure includes a partition wall vertically disposed within the chamber to separate a first flow channel and a second flow channel within the housing, and the partition wall has a vent and a valve structure disposed at the vent, wherein the valve structure conceals the vent when it is not pushed open. When the fluid pressure in one of the first and second flow channels in a section adjacent to the valve structure is greater than the fluid pressure in the other section adjacent to the valve structure, the valve structure is pushed open, exposing at least a portion of the vent.

[0006] In one embodiment of the present invention, the first flow channel may have a first section and a second section. The flow channel size of the first section is larger than the flow channel size of the second section. The valve structure may be located in the first section near the second section, or the valve structure may be located at the junction of the first section and the second section.

[0007] In one embodiment of the present invention, the valve structure described above includes two door panels. When the valve structure is pushed open, the two door panels can be opened in the same direction and extend together into the first flow channel or together into the second flow channel.

[0008] In one embodiment of the invention, when the valve structure is pushed open, one of the two door panels is opened and extends into the first flow channel or the second flow channel.

[0009] In one embodiment of the present invention, the heat dissipation assembly may further include at least one first stop structure disposed in at least one of the first flow channel and the second flow channel to limit the opening angle of the two door panels.

[0010] In one embodiment of the present invention, the heat dissipation assembly may further include at least one second stop structure disposed next to the two door panels to restrict the opening direction of the two door panels.

[0011] In one embodiment of the present invention, the two door panels are flexible and fixed to the partition wall.

[0012] In one embodiment of the present invention, the two door panels are rigid door panels and are pivotally connected to the partition wall.

[0013] In one embodiment of the present invention, the ratio of the length of each door panel to the width of the first flow channel may be between 0.2 and 0.6, and the ratio of the length of each door panel to the width of the second flow channel may be between 0.2 and 0.6.

[0014] In one embodiment of the invention, two door panels are adapted to move from a closed position to a fully open position. Each door panel has a first side connected to a partition wall and a second side opposite to the first side. When each door panel is in the fully open position, the position of the second side has a minimum distance from the position of the door panel when it is in the closed position. The ratio of the minimum distance to the width of a first flow channel can be between 0.2 and 0.6, and the ratio of the minimum distance to the width of a second flow channel can also be between 0.2 and 0.6.

[0015] Based on the above, the heat dissipation assembly of the present invention has a valve structure on the partition structure separating the first flow channel and the second flow channel. The valve structure can be opened and closed according to the liquid pressure in the first and second flow channels, so that some fluid flows from the opening to the other flow channel, thus having a diversion effect, reducing the fluid pressure in the flow channel and making the liquid flow smoothly. At the same time, some of the heat carried away by the heat source in the original flow path can be discharged out of the chamber earlier through the diversion effect of the valve structure, thereby accelerating the circulation of some fluid and improving the heat dissipation efficiency.

[0051] Figure 1 This is a perspective view of a heat dissipation assembly according to an embodiment of the present invention. Please refer to... Figure 1 The heat dissipation assembly 100 is adapted to dissipate heat from a heat source (not shown), which may be, for example, a central processing unit (CPU), memory, southbridge chip, northbridge chip, or graphics chip on a computer motherboard. In this embodiment, the heat dissipation assembly 100 has a housing 110 and a partition structure 120 disposed within the housing 110. The housing 110 has an upper housing 111 and a lower housing 113, and a chamber 112 is formed between the upper housing 111 and the lower housing 113. The upper housing 111 includes a first water hole 114 and a second water hole 116. The heat dissipation assembly 100 in... Figure 1 In order to clearly show the internal structure of the housing 110, the upper housing 111 is represented by a dashed line.

[0052] In this embodiment, the partition structure 120 includes a partition wall 122 vertically disposed in the chamber 112 of the housing 110, and the partition wall 122 of the partition structure 120 divides the chamber 112 into a first flow channel 150 and a second flow channel 160. Furthermore, the first flow channel 150 and the second flow channel 160 are connected, and liquid can enter the first flow channel 150 through the first water hole 114, flow from the first flow channel 150 to the second flow channel 160, and then flow from the second flow channel 160 to the second water hole 116. Moreover, this embodiment is described using the example of liquid entering the chamber 112 through the first water hole 114 and flowing out through the second water hole 116. In other embodiments, the liquid flow direction can also be reversed, depending on the user's usage habits, and is not limited here.

[0053] It is worth mentioning that during liquid flow, changes in the cross-sectional area of ​​the flow channel, such as different channel widths (wide channel flowing into narrow channel) or obstacles within the channel (e.g., fins or other structures that obstruct liquid flow or a difference in elevation within the channel), may increase flow resistance, making it difficult for the liquid to pass through. In this embodiment, the heat dissipation assembly 100 has a valve structure 124 on its partition structure 120, which can adjust the fluid pressure within the first flow channel 150 and the second flow channel 160 to ensure smooth liquid flow. This will be explained below.

[0054] Figure 2 yes Figure 1 An enlarged top view of region A of the heat dissipation component. Figure 3 yes Figure 2 This is a schematic diagram showing the valve structure of the heat dissipation component when it is open. Please refer to it. Figure 2 and Figure 3 In this embodiment, the first flow channel 150 has a first section 152 and a second section 154. In this embodiment, the partition wall 122 also has a breach 122a and a valve structure 124 disposed in the breach 122a. Of course, in other embodiments, the valve structure 124 of the present invention is not only applicable to... Figure 1 The heat dissipation component 100 shown.

[0055] In this embodiment, the valve structure 124 on the partition wall 122 of the partition structure 120 is located on the first section 152 of the first flow channel 150, and is close to the second section 154 of the first flow channel 150. In other embodiments, the valve structure 124 on the partition wall 122 may also be located at the junction of the first section 152 and the second section 154 of the first flow channel 150.

[0056] Furthermore, in this embodiment, the flow channel size of the first flow channel 150 located in the first section 152 is larger than the flow channel size of the first flow channel 150 located in the second section 154. Therefore, in this embodiment, when fluid flows from the first section 152 of the first flow channel 150 to the second section 154 of the first flow channel 150, the flow resistance increases due to the narrower flow channel size, thereby increasing the fluid pressure. Of course, in other embodiments, the first flow channel 150 may also have fins or other structures within the second section 154, affecting the flow resistance within the first flow channel 150; this invention is not limited to this.

[0057] Conversely, in this embodiment, since the fluid flow direction of the second flow channel 160 is opposite to the liquid flow direction of the first flow channel 150, and the channel size gradually increases with the flow direction, the flow resistance of the liquid is reduced due to the wider size of the second flow channel 160, thereby reducing the fluid pressure.

[0058] In this embodiment, the valve structure 124 includes two door plates 124a. When the valve structure 124 is pushed open, the two door plates 124a can be opened in the same direction and extend together into the first flow channel 150 or the second flow channel 160, so that the two door plates 124a are adapted to move from a closed position P1 to a maximum open position P2.

[0059] Furthermore, such as Figure 3 As shown, when the fluid pressure in the section of the first flow channel 150 near the valve structure 124 is greater than the fluid pressure in the section of the second flow channel 160 near the valve structure 124, the valve structure 124 will be pushed open by the fluid, and the two door plates 124a will extend into the second flow channel 160 together, thereby exposing at least part of the rupture 122a. Some liquid can flow from the first flow channel 150 to the second flow channel 160 through the rupture 122a, and then flow along the liquid in the second flow channel 160 to the second water hole 116 for discharge.

[0060] Similarly, in other embodiments, if the fluid pressure in the section of the second flow channel 160 near the valve structure 124 is greater than the fluid pressure in the section of the first flow channel 150 near the valve structure 124, the valve structure 124 will be pushed open by the fluid, and the two door plates 124a will extend into the first flow channel 150 together, and at least part of the rupture 122a will be exposed, allowing some liquid to flow from the second flow channel 160 to the first flow channel 150 through the rupture 122a.

[0061] In this embodiment, the heat dissipation assembly 100 has a valve structure 124 at the opening 122a in the partition wall 122. The valve structure can be opened and closed according to the liquid pressure of the first flow channel 150 and the second flow channel 160, allowing some fluid to flow through the opening, thus having a diversion effect to reduce the fluid pressure in one of the flow channels and make the liquid flow smoothly. At the same time, some of the heat carried away by the heat source in the original flow path can be discharged out of the chamber earlier through the diversion effect of the valve structure, thereby accelerating some fluid circulation and improving heat dissipation efficiency.

[0062] Furthermore, in this embodiment, the door panel 124a is made of a flexible material, such as rubber, and both door panels 124a are fixed to the partition wall 122, for example, through injection molding. That is, if the door panel 124a is made of rubber, when the valve structure 124 is pushed open by liquid, the door panel 124a may slightly deform and bend, exposing a portion of the opening 122a to allow some liquid to flow through. Of course, in other embodiments, the material of the door panel 124a can also be other suitable designs, and the present invention is not limited thereto.

[0063] Please refer to Figure 3In this embodiment, the valve plate 124a of the valve structure 124 also has a length L, and the ratio of the length L of each valve plate 124a to the channel width D1 of the first flow channel 150 can be, for example, between 0.2 and 0.6, and the ratio of the length L of each valve plate 124a to the channel width D2 of the second flow channel 160 can be, for example, between 0.2 and 0.6. This design ensures that the valve plate 124a does not close the first flow channel 150 or the second flow channel 160 when it is opened, avoiding obstruction of the flow space of the liquid in the first flow channel 150 or the second flow channel 160, which would lead to poor liquid flow or liquid backflow, thereby reducing the heat dissipation efficiency of the heat dissipation component 100.

[0064] It must be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals used to represent the same or similar components, and descriptions of the same technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

[0065] Figure 4 This is a partial top view of the valve structure of the heat dissipation assembly according to another embodiment of the present invention when it is open. Figure 4 As shown, Figure 4 and Figure 3 The main difference lies in that, in this embodiment, the heat dissipation assembly 100 further includes a first stop structure 130, which is disposed on the second flow channel 160 to limit the maximum opening angle of the door panel 124a. For example, when both door panels 124a extend into the second flow channel 160 simultaneously, the first stop structure 130 will limit the maximum opening angle of the door panel 124a, so that the door panel 124a can only be pushed to the maximum opening position P2, and will not be over-opened. Of course, in other embodiments, the first stop structure 130 may also be disposed within the first flow channel 150. Alternatively, the first stop structure 130 may be disposed within both the first flow channel 150 and the second flow channel 160, and the present invention is not limited thereto. In addition, the first stop structure 130 may be a convex structure disposed on the upper shell 111 or the lower shell 113, or a columnar structure connecting the upper shell 111 and the lower shell 113.

[0066] Furthermore, in this embodiment, each door panel 124a also has a first side 126 connected to the partition wall 122 and a second side 128 opposite to the first side 126. When each door panel 124a moves from the closed position P1 to the maximum open position P2 restricted by the first stop structure 130, the position of each door panel 124a on the second side 128 of the maximum open position P2 is the same as the position of each door panel 124a on the second side 128 of the maximum open position P2. Figure 3The position shown in the closed position P1 has a minimum distance D3, which is the projection distance of the second side 128 relative to the opening 122a. In this embodiment, when the door panel 124a extends into the second flow channel 160 and is opened to the maximum open position P2, the ratio of the minimum distance D3 to the corresponding flow channel width of the second flow channel 160 (e.g., the width D2' of the second flow channel 160 at the location of the second side 128 of the door panel 124a) is between 0.2 and 0.6. Therefore, the door panel 124a will not obstruct too much of the flow channel space of the second flow channel 160, thus preventing poor liquid flow or liquid backflow, which could affect the heat dissipation assembly 100. Figure 1 ( ) heat dissipation efficiency.

[0067] Figure 5 This is a partial perspective view of the valve structure of the heat dissipation assembly according to another embodiment of the present invention when it is open. Please refer to... Figure 5 , Figure 5 The partition structure 120' and Figure 3 The difference between the partition structure 120 and the previous one is that, in this embodiment, the door panels 124a of the valve structure 124 are rigid door panels, each door panel 124a is pivotally connected to the partition wall 122 via a pivot portion 70, and each door panel 124a is adapted to rotate relative to the partition wall 122 of the partition structure 120' by being pushed by the liquid. Furthermore, when the door panel 124a is made of a flexible material, it can also be pivotally connected to the partition wall 122 via the pivot portion 70.

[0068] Figure 6 This is a partial top view of the valve structure of the heat dissipation assembly according to another embodiment of the present invention when it is open. Figure 7 yes Figure 6 Please refer to the partial 3D schematic diagram of the valve structure of the heat dissipation component when it is open. Figure 6 and Figure 7 , Figure 6 The 120'' separator structure and Figure 3 The main difference of the partition structure 120 is that, in this embodiment, when the valve structure 124 is pushed open, only one door panel 124a is open. As shown, when the pressure in the first flow channel 150 is greater than the pressure in the second flow channel 160, one door panel 124a will extend into the second flow channel 160 and open, while the other door panel 124a will remain closed.

[0069] In this embodiment, the heat dissipation assembly 100 further includes a second stop structure 140, which can be disposed at the opening 122a of the partition wall 122 and located next to the two door panels 124a, to restrict the opening direction of the two door panels 124a. For example, as Figure 7As shown, in this embodiment, the second stop structure 140 can be a frame, which allows liquid to pass through and limits the door pieces 124a. The two door pieces 124a are respectively disposed on the side of the second stop structure 140 (frame) near the first flow channel 150 and the side of the second stop structure 140 (frame) near the second flow channel 160. That is, the frame (second stop structure 140) is used to restrict the opening direction of the two door pieces 124a, so that one door piece 124a can only extend into the first flow channel 150, and the other door piece 124a can only extend into the second flow channel 160. Of course, in other embodiments, the second stop structure 140 can be designed in other suitable forms, such as convex or columnar, and the present invention is not limited thereto.

[0070] Furthermore, in other embodiments, the first stop structure 130 and the second stop structure 140 may coexist and may be configured in the first flow channel 150 and the second flow channel 160 or in other suitable positions, and the present invention is not limited thereto.

[0071] In addition, in other embodiments, the shapes of the second sides 128 of the two door panels 124a can be matched with each other, such as a point-symmetric shape configuration, a stepped matching as shown in the figure, or a beveled matching, to ensure that the valve structure 124 can be opened in both directions and can fit together when closed.

[0072] In summary, the heat dissipation assembly of the present invention incorporates a valve structure in the partition structure separating the first and second flow channels. This valve structure can be opened and closed according to the liquid pressure in the first and second flow channels, allowing some fluid to flow through the opening and thus achieving a diversion effect. This reduces the fluid pressure in one of the flow channels and ensures smooth liquid flow. Simultaneously, some of the heat carried away by the heat source along the original flow path can be expelled from the chamber earlier through the diversion effect of the valve structure, thereby accelerating some fluid circulation and improving heat dissipation efficiency. In other words, the heat dissipation assembly of the present invention reduces the probability of the cooling liquid being unable to flow smoothly due to excessive flow resistance and reduces the circulation time of some fluid, thereby ensuring good heat dissipation efficiency.

[0073] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
