Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and more specifically, to a heat dissipation plate and a heat dissipation module including the aforementioned heat dissipation plate. Background Technology

[0002] A typical vapor chamber consists of a cavity, capillaries, and an internal working fluid. The cavity is typically made of copper, and the working fluid is pure water. The inner wall of the vapor chamber has a vacuum cavity with a microcapillary structure. When heat is conducted from the heat source to the evaporation zone, the working fluid inside the cavity will begin to vaporize in a low-vacuum environment. At this time, the working fluid absorbs heat energy and expands rapidly. The gaseous working fluid will quickly fill the entire cavity. When the gaseous working fluid comes into contact with a cooler heat dissipation area composed of fins, condensation will occur. The heat accumulated during evaporation is released through condensation. The condensed liquid working fluid will return to the evaporation heat source through the capillary effect of the microcapillary structure. This operation will repeat heat exchange within the cavity.

[0003] In existing technologies, when assembling vapor chambers with other components in a module, soldering methods such as tin soldering are typically used to weld the vapor chamber and the module components. To ensure welding quality and reduce weld voids, integrally formed bumps (also known as support bumps) are usually machined on the vapor chamber to control the solder thickness during welding. The thickness of the solder is controlled by the limiting support of the bumps. However, this results in an increase in material thickness and CNC machining costs.

[0004] In the process of realizing this utility model, the inventor discovered that at least the following problems exist in the prior art: the temperature distribution plate is difficult to process. Utility Model Content

[0008] In the aforementioned vapor chamber, during processing, there is no need to directly machine support protrusions onto the welding surface of the vapor chamber substrate. Instead, the individual structural components, such as the support protrusions, are directly assembled onto the welding surface to form a vapor chamber with support protrusions. During vapor chamber installation, external structures, such as heat source modules, are placed on the support protrusions. Due to the support and restraint provided by the protrusions, a uniform gap is formed between the corresponding side of the external structure and the aforementioned welding surface, thereby ensuring uniform solder distribution and guaranteeing welding quality. This vapor chamber with support protrusions ensures uniform welding with external structures. Furthermore, the support protrusions and the vapor chamber are assembled together, rather than being integrally connected, which effectively reduces manufacturing costs. The support protrusions primarily serve a supporting function; therefore, general assembly is sufficient to meet the support requirements. In summary, this vapor chamber effectively addresses the problem of the high difficulty in processing vapor chambers.

[0012] In some technical solutions, the support protrusion is elongated and its extension direction is perpendicular to the length direction.

[0013] In some technical solutions, in a first direction, on both sides of the heated area, the support protrusions adjacent to the heated area are elongated protrusions; the elongated protrusions extend along a second direction, at least from one end of the heated area to the other end; the first direction is perpendicular to the second direction.

[0014] In some technical solutions, the elongated protrusion is located away from the heated area on the side, and the multiple supporting protrusions are short protrusions arranged in parallel along the second direction; the short protrusions are elongated and / or block-shaped.

[0015] In some technical solutions, the supporting protrusion is a polyimide film substrate; the supporting protrusion is bonded to the welding surface by high-temperature resistant silicone adhesive; the protrusion height of the supporting protrusion relative to the welding surface is between 0.04 mm and 0.18 mm; the maximum non-deformation temperature that the supporting protrusion can withstand is not less than 100 degrees Celsius; and the welding surface is a plane.

[0016] In some technical solutions, one side of the heat-equalizing substrate along the thickness direction includes a heat dissipation surface, and the other side includes the welding surface; the heat-equalizing substrate includes a heating plate, a heat dissipation plate, a capillary structure, and at least one support column; at least one of the heating plate and the heat dissipation plate has a groove-shaped structure to form a heat-equalizing cavity between them; the support column extends along the thickness direction, and its two ends are integrally formed and connected to one of the heating plate and the heat dissipation plate, respectively, and abut against the other; the capillary structure is located in the heat-equalizing cavity and includes a flat plate portion abutting against the heating plate, a sleeve portion sleeved on the support column, and a side plate portion abutting against the groove wall of the groove-shaped structure; one end of the sleeve portion is connected to the flat plate portion, and the other end abuts against the heat dissipation plate; one end of the side plate portion is connected to the flat plate portion, and the other end abuts against the heat dissipation plate.

[0017] To achieve the second objective mentioned above, this utility model also provides a heat dissipation module, which includes any of the aforementioned heat spreaders and a heat dissipation object. One side of the heat dissipation object has a heat source area, and the mounting surface faces the welding surface of the heat spreader and abuts against a supporting protrusion of the heat spreader. The heated area of ​​the heat spreader corresponds to the heat source area. Since the aforementioned heat spreader has the above-mentioned technical effects, the heat dissipation module with this heat spreader should also have corresponding technical effects.

[0032] This utility model discloses a heat spreader plate to effectively solve the problem of the high processing difficulty of heat spreader plates.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5 , Figure 1 A schematic diagram of the structure of a heat spreader provided in an embodiment of this utility model; Figure 2 An exploded view of a temperature distribution plate provided in an embodiment of this utility model; Figure 3 A schematic diagram of the structure of a heat spreader provided in an embodiment of this utility model; Figure 4 A schematic diagram of the structure of a heat spreader provided in an embodiment of this utility model; Figure 5 This is a schematic diagram of the structure of a temperature distribution plate provided in an embodiment of the present utility model.

[0035] In some embodiments, a vapor chamber, also known as a heat spreader, heat conduction plate, or VC (Vaporchamber) plate, is provided. The vapor chamber is used for welding to a heat source module (also known as a heat dissipation object). At least one side of the vapor chamber is a welding surface 111 for welding to the corresponding side of the heat source module. Solder is placed between them. To ensure uniform solder distribution, a uniform gap along the extension direction needs to be formed between the welding surface 111 and the corresponding side of the heat source module. Therefore, support protrusions 2 are provided on the welding surface 111 to support the heat source module and ensure a uniform gap between them. The support protrusions 2 can be arranged at multiple points, in a U-shape, or in other forms.

[0036] The supporting protrusion 2 and the welding surface 111 are not integrally connected, but rather assembled together. Assembly refers to the connection of two individual components through one or more methods, which is different from integral connection. In this context, assembly can also be directly understood as non-integral connection. By assembling them together, direct machining on the welding surface 111 is avoided, such as avoiding direct CNC machining (computer numerical control machining), thus reducing manufacturing costs.

[0037] In some embodiments, a heat spreader is provided, including a heat spreader substrate 1 and at least one support protrusion 2 assembled with the substrate. If the assembly is not integral, the two individual components, heat spreader substrate 1 and support protrusion 2, can be connected together by welding, overlapping, bearing, bonding, magnetic attraction, or other connection methods.

[0038] At least one of the support protrusions 2 rests against the welding surface 111 on the heat spreader substrate 1, which is used for welding to an external structure, and protrudes from the welding surface 111. "Rests against" means that the corresponding sides of the two are positioned opposite each other, allowing for direct contact or indirect contact through other structures. The external structure is, for example, the heat source module described above. The protrusion from the welding surface 111 primarily prevents the heat source module from directly contacting the welding surface 111 and maintains a stable gap. Specifically, when there is only one support protrusion 2, the side of the support protrusion 2 away from the welding surface 111 is a plane parallel to the welding surface 111; while when there are multiple support protrusions 2, the surface containing the vertices of each support protrusion 2 on the side away from the welding surface 111 is a plane, and is parallel to the welding surface 111. When there are multiple vertices or multiple vertices forming a plane in the support protrusion 2, any point can be selected as the vertex.

[0039] In the aforementioned vapor chamber, during processing, it is unnecessary to directly machine the support protrusions 2 onto the welding surface 111 of the vapor chamber substrate 1. Instead, the individual structural components, such as the support protrusions 2, are directly assembled onto the welding surface 111 to form a vapor chamber with support protrusions 2. During vapor chamber installation, external structures, such as heat source modules, are placed on the support protrusions 2. Due to the support and restraint provided by the support protrusions 2, a uniform gap is formed between the corresponding side of the external structure and the welding surface 111, thereby ensuring uniform solder distribution and guaranteeing welding quality. The aforementioned vapor chamber with support protrusions 2 ensures uniform welding with external structures. Furthermore, the support protrusions 2 and the vapor chamber are assembled and connected, rather than being integrally connected, which effectively reduces manufacturing costs. The support protrusions 2 primarily serve a supporting function, so general assembly is sufficient to meet the support requirements. In summary, this vapor chamber effectively addresses the problem of the high difficulty in processing vapor chambers.

[0040] In some embodiments, the support protrusion 2 can be fixedly connected to the welding surface 111, and the fixed connection method can be such as welding connection, adhesive connection or snap-fit, to facilitate transportation.

[0041] Of course, a movable connection can also be used. For example, the support protrusion 2 can have a predetermined range of motion in the extension direction of the welding surface 111. In this case, the support protrusion 2 and the welding surface 111 can be simply overlapped.

[0042] In some embodiments, multiple support protrusions 2 can be arranged in an array to achieve multi-point support, thereby improving the stability of the support, avoiding the use of large support protrusions 2, and making installation with the welding surface 111 more convenient and reducing installation costs. The array arrangement can be, for example, a square array or a circular array.

[0043] As attached Figure 1 , 3 The arrays shown are all square arrays. And as attached... Figure 1 As shown, 2*3 arrays (* indicates multiplication) are formed on both sides of the heated zone 112, as shown in the attached diagram. Figure 3 As shown, 2*2 arrays are formed on both sides of the heated zone 112.

[0044] In some embodiments, at least one support protrusion 2 is a circular plate structure, and / or at least one support protrusion 2 is a square plate structure, and / or at least one support protrusion 2 is a strip-shaped plate structure. Specifically, the various support protrusions 2 may have the same structure, such as all being circular plate structures, all being strip-shaped plate structures, etc. Of course, they may also include multiple different structures, as shown in the attached diagram. Figure 5 As shown, both circular and strip structures are arranged. The circular structures include square and rhomboid sheet-like structures. The strip structures, as shown in the attached diagram... Figure 3 ,4 5 is a rectangular structure, but it can also be an oblong structure.

[0045] One example, as shown in the appendix Figure 1 As shown, at least one of the supporting protrusions 2 is a circular plate structure, which can avoid corner curling, and it is a point structure, so the support effect is better.

[0046] One example, as shown in the appendix Figure 3 , 4 As shown, at least one of the supporting protrusions 2 is a long strip structure. The long strip structure has a good limiting effect on the solder, preventing it from flowing freely.

[0047] In some embodiments, the welding surface 111 may include a heated area 112 for contacting a heat source. Generally, the support protrusion 2 needs to be arranged away from the heated area 112. It may be arranged around the heated area 112 or separately on both sides of the heated area 112. The heated area 112 is arranged corresponding to the heat source area of ​​the heat source structure to achieve efficient direct or indirect thermal contact.

[0048] Generally, the support protrusions 2 are provided on both sides of the heated zone 112 in at least one direction to support the heat source structure from both sides of the heated zone 112 and ensure the stability of the support.

[0049] Generally, the width of the heated zone 112 in this direction is significantly greater than the distance between adjacent support protrusions 2 on any one side. For elongated protrusions, their width is significantly smaller than the width of the heated zone 112.

[0050] In some embodiments, to achieve uniform heat dissipation, a heated area 112 may be provided at the midpoint of the length direction of the welding surface 111. Specifically, the heated area 112 is arranged at the midpoint of the length direction of the welding surface 111. The length direction is described relative to the width direction; of the two perpendicular directions, the one with the longer dimension is the length direction, and the one with the shorter dimension is the width direction. (See attached...) Figure 3 , 4 5. In the diagram, the first direction X is the length direction, and the second direction Y is the width direction.

[0051] In some embodiments, to reduce interference, each support protrusion 2 can be arranged on both sides of the heated area 112 along its length. Specifically, of all the support protrusions 2, a portion of the support protrusions 2 are arranged on one side of the heated area 112 along its length, while another portion of the support protrusions 2 are arranged on the other side of the heated area 112 along its length.

[0052] In some embodiments, to provide uniform support on both sides, the heated area 112 may have an array of protrusions on both sides, wherein the array of protrusions consists of multiple rows and / or columns of the support protrusions 2. For example, the row direction (the direction in which the structures in a row are arranged side-by-side) is a first direction X, and the column direction (the direction in which the structures in a column are arranged side-by-side) is a second direction Y. (See attached...) Figure 1 As shown, the support protrusions 2 on both sides of the heated zone 112 are in a 3*2 array; as shown in the attached diagram. Figure 3 As shown, the support protrusions 2 on both sides of the heated zone 112 are both 2*2 arrays; as attached Figure 4 As shown, the support protrusions 2 on both sides of the heated zone 112 are both 1*2 arrays.

[0053] In some embodiments, the support protrusion 2 can be elongated and its extension direction is perpendicular to the length direction. As shown in the figure, the support protrusion 2 extends along the second direction Y to prevent the solder from flowing along the first direction X, that is, the solder flows along the length direction, which can avoid or reduce the outflow of solder in the heated area 112.

[0054] In some embodiments, in the first direction X, on both sides of the heated area 112, the supporting protrusion 2 adjacent to the heated area 112 is an elongated protrusion 21; wherein the elongated protrusion 21 extends along the second direction Y for a length that extends at least from one end of the heated area 112 to the other end; the first direction X and the second direction Y are perpendicular to each other. In one example, the first direction X is the length direction of the welding surface 111, and the second direction Y is the width direction of the welding surface 111. The elongated protrusion 21 extends along the second direction Y for a length that extends at least from one end of the heated area 112 to the other end, that is, in the second direction Y, both ends of the elongated protrusion 21 are not shorter than both ends of the heated area 112, as shown in the attached figure. Figure 4 , 5 As shown, both ends of the elongated protrusion 21 are longer than both ends of the heated area 112, that is, they protrude from both ends of the heated area 112.

[0055] The adjacent support protrusions 2 of the heated zone 112 are elongated protrusions 21, and their length in the second direction Y is sufficient to ensure that the corresponding part of the solder in the heated zone 112 flows along the first direction X, so as to fully ensure that the solder in the heated zone 112 is uniform and sufficient.

[0056] In some embodiments, to facilitate the arrangement of the support protrusions 2, the elongated protrusions 21 can be positioned away from the heated area 112, and the plurality of support protrusions 2 can be short protrusions 22 arranged side by side along the second direction Y; the short protrusions 22 are elongated and / or block-shaped, wherein the block shape is such as a circular or square plate structure. (See attached...) Figure 5 As shown, the short protrusion 22 is a circular support protrusion 2. The long protrusion 21 is positioned away from the heated area 112. Multiple support protrusions 2 can be arranged in an array, as shown in the attached diagram. Figure 5 The image shows a 3x2 array.

[0057] In some embodiments, the support protrusion 2 can be a polyimide film substrate, which has strong stability. Of course, the support protrusion 2 can also be a metal sheet.

[0058] In some embodiments, the support protrusion 2 and the welding surface 111 can be bonded together with high-temperature resistant silicone adhesive, wherein the high-temperature resistant silicone adhesive has properties such as high temperature resistance, corrosion resistance, high insulation, high adhesion, softness and fit, and no residue after removal. Of course, other adhesives can also be used.

[0059] In some embodiments, the height of the support protrusion 2 relative to the welding surface 111 is between 0.04 mm and 0.18 mm, such as 0.05 mm or 0.15 mm.

[0060] In some embodiments, the maximum non-deformation temperature (also understood as high temperature resistance) that the support protrusion 2 can withstand is not less than 100 degrees Celsius. Specifically, the high temperature resistance range of the support protrusion 2 can be 100~300 degrees Celsius.

[0061] In some embodiments, the welding surface 111 is generally flat to ensure processing accuracy and reduce processing costs. Conversely, for ease of assembly, the portion of the welding surface 111 corresponding to the support protrusion 2 may be provided with a groove to mate with the bottom of the support protrusion 2.

[0062] In some embodiments, the temperature-equalizing substrate 1 includes a heat dissipation surface on one side along the thickness direction Z, and the welding surface 111 on the other side; the temperature-equalizing substrate 1 includes a heat-receiving plate 11, a heat dissipation plate 12, a capillary structure 13, and at least one support column 14, which may be an array of multiple support columns 14.

[0063] At least one of the heating plate 11 and the heat dissipation plate 12 has a groove-shaped structure to form a temperature-equalizing cavity between them, as shown in the attached figure. Figure 2 As shown, a groove-shaped structure is formed at the heating plate 11, while the heat dissipation plate 12 is a flat plate to cover the groove of the heating plate 11 and to seal the connection. Generally, the heat exchange chamber is also provided at the filling port 15, which can be arranged on the groove wall and is provided on the outer side of the groove wall.

[0064] The support column 14 extends along the thickness direction Z of the plate, and its two ends are integrally formed and connected to the heat-receiving plate 11 and the heat dissipation plate 12 respectively, and abut against the other. The support column 14 is integrally formed and connected to the heat-receiving plate 11, while it can be welded to the heat dissipation plate 12. The support column 14 can be a cylindrical column, a square column, a solid column, or a hollow column. (See attached image) Figure 2 As shown, 3*5 support columns are arranged on the inner side.

[0065] The capillary structure 13 is located within the temperature equalization chamber and includes a flat plate portion 131 abutting against the heating plate 11, a sleeve portion 132 sleeved on the support column 14, and a side plate portion 133 abutting against the wall of the groove-shaped structure. One end of the sleeve portion 132 abuts against the flat plate portion 131, and the other end abuts against the heat dissipation plate 12. Preferably, the inner diameter of the sleeve portion 132 is equal to the outer diameter of the support column 14. One end of the side plate portion 133 abuts against the flat plate portion 131, and the other end abuts against the heat dissipation plate 12. Multiple side plate portions 133 surround to form a frame-like structure, such as a square frame structure. Generally, the flat plate portion 131, the sleeve portion 132, and the side plate portion 133 are integrally sintered.

The heat dissipation module includes any one of the heat spreaders in the above embodiments, and includes a heat dissipation object. One side of the heat dissipation object has a heat source area. The mounting surface is opposite to the welding surface 111 of the heat spreader and abuts against the support protrusion 2 of the heat spreader. The heated area 112 of the heat spreader is correspondingly provided with the heat source area. Since this heat dissipation module uses the heat spreader in the above embodiments, the beneficial effects of this heat dissipation module can be found in the above embodiments.

[0067] When air-cooled modules, water-cooled modules, etc. are installed, they are generally placed on the heat dissipation surface.
