Description

Technical Field

[0001] The present invention relates to the technical field of electronic components, and in particular to a high-efficiency heat dissipation module in which VC replaces traditional fins. Background Art

[0002] A vapor chamber, also commonly called a temperature vapor chamber or VC vapor chamber, is a vacuum chamber with a microstructured inner wall, usually made of copper. When heat is conducted from the heat source to the evaporation zone, the coolant in the chamber begins to vaporize after being heated in a low vacuum environment. At this time, it absorbs heat energy and expands rapidly in volume. The gaseous cooling medium quickly fills the entire chamber. When the gaseous working medium contacts a relatively cold area, condensation will occur, and the heat accumulated during evaporation will be released through condensation. The condensed coolant will return to the evaporation heat source through the microstructured capillary channels, and this operation will be repeated in the chamber. The traditional fin heat dissipation efficiency is insufficient to meet the heat dissipation needs. VC vapor chambers are the mainstream of heat dissipation devices.

[0003] For example, a VC vapor chamber heat sink is disclosed in a Chinese patent (CN219761797U), comprising a VC vapor chamber, a fixing part being fixedly installed on the outer surface of the VC vapor chamber, the fixing part being used to facilitate fixing the VC vapor chamber, a heat sink being fixedly installed on the top of the VC vapor chamber, the heat sink being used to increase the heat dissipation area and accelerate the heat dissipation of the VC vapor chamber, the VC vapor chamber comprising a heat input surface and a heat output surface, the heat input surface being located at the bottom end of the VC vapor chamber, the heat output surface being located at the top end of the VC vapor chamber, and the heat output surface being fixedly connected to the heat sink, an installation cavity being provided inside the VC vapor chamber, a vacuum cavity being fixedly installed on the inner cavity side wall of the installation cavity, a capillary structure being formed between the vacuum cavity and the installation cavity, the utility model can not only perform efficient heat dissipation, but also has strong thermal conductivity and good temperature uniformity performance.

[0004] The above scheme also has the following technical defects. The above scheme only uses one VC heat spreader for heat dissipation, and its main heat dissipation device is still the heat sink. Due to the limited thermal conductivity of the heat sink, the heat dissipation efficiency of the above scheme is limited. At the same time, the above convenient VC heat spreader is flat, which is difficult to manufacture and the coolant reflux speed is slow. Based on this, an efficient heat dissipation module is proposed in which VC replaces traditional fins. Summary of the invention

[0031] The fixing assembly 500 in this embodiment is fixed to four first fixing plates 501 on the top side of the heat conducting plate 4 and four second fixing plates 502 fixed to the top side of the heat conducting plate 4 and located on the corresponding side of the first fixing plate 501. The internal thread of the first fixing plate 501 is connected with a screw rod 503. A connecting hole is opened inside the mounting plate 6. The screw rod 503 passes through the connecting hole. An abutment plate 504 is fixed to the outer surface of the screw rod 503. A handle 505 is fixed to the side of the screw rod 503 away from the first fixing plate 501. The side of the abutment plate 504 close to the second fixing plate 502 abuts against the corresponding side of the second fixing plate 502.

[0032] It should be noted that the mounting mechanism 200 is used to facilitate the installation and disassembly of the VC heat spreader 300, the fixing assembly 500 is used to facilitate the fixing of the mounting plate 6 and the fan 7 on the heat conducting plate 4, the fan 7 is used to dissipate heat from the heat conducting plate 4, the heat conducting plate 4 is used for heat conduction, the heat source groove 8 is used to place the heat source, and the through hole 9 is used to facilitate the fixing of the heat dissipation module.

Two air holes 307 are provided inside the capillary plate 303, and the interior of the capillary structure 302 constitutes a vacuum cavity 308.

[0034] The VC heat spreader 300 in this embodiment can facilitate the reflux of the coolant through the capillary structure 302. The capillary plate 303 is used to evaporate the coolant that has refluxed into the capillary plate 303 again, thereby achieving evaporative heat dissipation on the two surfaces of the capillary plate 303 and the top side of the capillary structure 302, which can improve the efficiency of evaporative heat dissipation. By arranging the first capillary tube 304 and the second capillary tube 305 at an angle, the path for the coolant to reflux to the bottom side of the capillary structure 302 can be shortened, and at the same time, the path for the coolant to reflux is increased compared to using the capillary structure 302 alone.

[0035] It should be noted that the air holes 307 are used to facilitate the hot steam to rise, and the support column 306 is used to support the capillary structure 302 and the shell 301 .

[0036] See also Figure 1 , Figure 4 and Figure 5 In order to facilitate the installation and replacement of the VC heat spreader 300, the installation mechanism 200 in this embodiment includes a plurality of connecting plates 201 fixed to the top side of the base 1 and the bottom side of the heat conducting plate 4, two vertical plates 202 fixed to the front side of the VC heat spreader 300, and abutment grooves 207 opened inside the front side walls of the connecting plates 201. The top and bottom sides of the connecting plates 201 are both open. The top side of the VC heat spreader 300 can be abutted against the top side of the heat conducting plate 4, and the bottom side of the VC heat spreader 300 can be abutted against the top side of the heat conducting plate 4, and the bottom side of the VC heat spreader 300 can be abutted against the The top sides are abutted against each other, a spring 203 is fixed inside the vertical plate 202, an elastic block 204 is fixed on the front side of the spring 203, the elastic block 204 can abut against the abutment groove 207, two connecting rods 205 are fixed on the rear side of the elastic block 204, two limit blocks 206 are fixed on the rear side of the connecting rod 205, and limit grooves are provided on the upper and lower sides of the inner wall of the vertical plate 202, the two limit blocks 206 slide in the corresponding limit grooves, and the VC heat spreader 300 is inserted into the two corresponding upper and lower connecting plates 201.

[0037] The mounting mechanism 200 in this embodiment can fix the VC heat spreader 300 by the elastic block 204 abutting against the abutting groove 207 and the vertical plate 202 abutting against the connecting plate 201. The spring 203 is used to facilitate the elastic block 204 to temporarily move into the vertical plate 202 when entering the connecting plate 201.

[0038] It should be noted that the openings on the top and bottom sides of the connection plate 201 can prevent the connection plate 201 itself from affecting the heat dissipation efficiency of the VC heat spreader 300 , and the limit block 206 can limit the elastic block 204 by sliding in the limit groove.

[0039] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0040] When in use, the base 1 introduces the heat generated by the heat source into the VC heat spreader 300, and the cooling liquid in the capillary structure 302 is heated and evaporated, and the cooling liquid becomes hot steam and moves out from the top side of the bottom end of the capillary structure 302. After reaching the top side of the capillary structure 302, the hot steam is cooled and turned into cooling liquid. Part of the cooling liquid flows back to the bottom end of the capillary structure 302 along the left and right sides of the capillary structure 302, and at the same time, part of the cooling liquid flows into the capillary plate 303 along the second capillary tube 305, and the remaining cooling liquid flows back to the bottom side of the capillary structure 302 along the first capillary tube 304. After being heated, the cooling liquid in the capillary plate 303 becomes hot steam and rises to the top side of the capillary structure 302. This cycle is used to achieve heat dissipation. The VC heat spreader 300 transfers the heat to the heat conducting plate 4, and the fan 7 further removes the heat from the heat conducting plate 4. When the VC heat spreader 300 needs to be replaced, the heat conducting plate 4 and the connecting plate 201 located above are removed from the VC heat spreader 300, and the elastic block 204 moves backward under the pressure of the connecting plate 201. The elastic block 204 squeezes the spring 203 to deform it, and the elastic block 204 enters the vertical plate 202. The elastic block 204 and the VC heat spreader 300 are pulled out of the connecting plate 201, and then the VC heat spreader 300 that needs to be replaced is taken out for replacement, and then the connecting plate 201 located above is installed on the corresponding VC heat spreader 300.
