Embodiment 1

[0056] like Figure 1-7 As shown, this embodiment lists a sintering device for manufacturing a vapor chamber, including a box body 110 and a sintering mechanism 120 disposed inside the box body 110;

[0057] The sintering mechanism 120 includes a hot pressing workbench 1201 and a water cooling assembly 1202;

[0061] The water cooling part 12021 includes a first water cooling part 120211 and a second water cooling part 120212. The first water cooling part 120211 includes a first water cooling channel 210 and a first circulating water pipe 220. A plurality of first water cooling channels 210 are arranged inside the upper transfer copper plate 12013 and the lower transfer copper plate 12014. The water inlets and water outlets of the plurality of first water cooling channels 210 are respectively connected to the plurality of first circulating water pipes 220.

[0062] The second water-cooling member 120212 includes a second water-cooling channel 230, a gathering channel 240, a dispersion channel 250, and a second circulating water pipe 260. A plurality of second water-cooling channels 230, a gathering channel 240, and a plurality of dispersion channels 250 are all arranged inside the conductive copper column 12015. A plurality of second water-cooling channels 230 converge into a gathering channel 240, and the gathering channel 240 is connected to a plurality of dispersion channels 250.

[0063] The first circulating water pipe 220 is connected to a water source. The first circulating water pipe 220 includes two water pipes, one connected to the water inlet of the first water cooling channel 210, and the other connected to the water outlet of the first water cooling channel 210. The water pipe connected to the water inlet is connected to a pressure pump and then connected to a water source. The other water pipe is directly connected to the water source.

[0064] The second circulating water pipe 260 is the same as above, the first water cooling channel 210 is mainly responsible for cooling the upper transfer copper plate 12013 and the lower transfer copper plate 12014, and the second water cooling channel 230 is mainly responsible for cooling the conductive copper column 12015 and the heat spreader;

[0065] In this embodiment, the second water-cooling channel 230 is divided into two sections. The second water-cooling channel 230 in the first section is connected to the aggregate channel 240. The aggregate channel 240 first separates multiple dispersed channels 250, and then the multiple dispersed channels 250 are aggregated in the second water-cooling channel 230 in the second section.

[0066] The adjustment part 12022 includes a fixing piece 310 and an adjustment piece 320. The fixing pieces 310 are fixedly arranged inside the aggregate channel 240. The fixing pieces 310 are arranged equidistantly in a linear array. An adjustment piece 320 is movably arranged on each fixing piece 310.

[0067] The fixing plate 310 is a semicircular fan-shaped structure, and the adjusting plate 320 is the same shape as the fixing plate 310 , and the two have overlapping parts.

[0068] In this embodiment, the fixing plate 310 stably occupies half of the space of the aggregate channel 240, and the adjusting plate 320 initially overlaps with the fixing plate 310, and the aggregate channel 240 is opened to the maximum. When the hydraulic system 12011 moves downward, the adjusting plate 320 begins to separate from the fixing plate 310, and the relative positions of the fixing plate 310 and the adjusting plate 320 in the aggregate channel 240 change, so that the adjusting plate 320 cooperates with the fixing plate 310 to close the aggregate channel 240. When the hydraulic system 12011 moves downward to the maximum distance, the aggregate channel 240 is completely closed, and the cooling water inside the aggregate channel 240 does not flow. At this time, The hot pressing stage is performed. After the hot pressing stage is over, when the cooling water starts to enter from the water-cooling channel, the hydraulic system 12011 moves upward, and the adjusting plate 320 starts to aggregate with the fixed plate 310. The relative positions of the fixed plate 310 and the adjusting plate 320 in the aggregate channel 240 change, so that the adjusting plate 320 cooperates with the fixed plate 310 to open the aggregate channel 240. When the hydraulic system 12011 moves up to the maximum distance, the aggregate channel 240 is fully opened. The different sizes of the opening and closing of the aggregate channel 240 are adjusted by the different rising heights of the hydraulic system 12011. The cooling water circulation speed is different and the cooling level is also different.

[0069] The transmission assembly 140 includes a rack 1401, a main gear 1402, a transmission gear 1403 and a connecting shaft 1404. The rack 1401 is arranged on the sealed box 130. A mounting piece is arranged on the movable plate 12012. The main gear 1402 is movably arranged on the mounting piece. The rack 1401 is meshed with the main gear 1402. The transmission gear 1403 is movably arranged on the inner wall of the box body 110. The main gear 1402 is meshed with the transmission gear 1403. One end of the connecting shaft 1404 is connected to the transmission gear 1403, and the other end of the connecting shaft 1404 is connected to a plurality of adjusting pieces 320.

[0070] The rack 1401 moves up and down to drive the main gear 1402 to rotate. The main gear 1402 rotates to drive the transmission gear 1403 to rotate. The transmission gear 1403 rotates the fixing plate 310 through the connecting shaft 1404 .

[0071] In this embodiment, when the rack 1401 moves downward, that is, the hydraulic system 12011 moves the movable plate 12012 downward to perform the hot pressing stage, the rack 1401 moves downward to drive the main gear 1402 to rotate clockwise, the main gear 1402 drives the transmission gear 1403 to rotate counterclockwise, and the transmission gear 1403 causes the adjustment piece 320 to rotate counterclockwise through the connecting shaft 1404. The relative position between the adjustment piece 320 and the fixed piece 310 changes, and each adjustment piece 320 and the fixed piece 310 are spaced apart from the dispersion channel 250.

[0072] A circular groove 410 is provided on the top of the sealing box 130, and the conductive copper column 12015 enters the sealing box 130 through the circular groove 410, and a sealing ring 420 is provided at the contact point between the conductive copper column 12015 and the circular groove 410;

[0073] In this embodiment, the sealing ring 420 is mainly attached to the contact between the conductive copper pillar 12015 and the circular groove 410. The contact between the sealing ring 420 and the conductive copper pillar 12015 also needs to be relatively smooth so that the conductive copper pillar 12015 can also slide.

[0074] Among them, the circular groove 410 connects the interior of the sealed box 130 and the interior of the box body 110, and the conductive copper column 12015 can move up and down through the circular groove 410. In order to avoid leakage, sealing rings 420 are provided on the upper and lower surfaces where the conductive copper column 12015 and the sealed box 130 contact to prevent leakage.

[0075] A temperature measuring device 430 is disposed on one side of the sealed box 130 , a box door 1301 is disposed on the front of the sealed box 130 , and an observation window 1302 is disposed on the box door 1301 ;

[0076] The temperature detector 430 can detect the temperature inside the sealed box 130 , and then control the temperature through electrical control to perform temperature control of hot pressing. The situation inside the sealed box 130 can be observed through the observation window 1302 .

[0077] A plurality of sleeves 510 are disposed on the box body 110, and a movable rod 520 is movably disposed in each sleeve 510, and each movable rod 520 passes through the box body 110 and is connected to the top of the movable plate 12012;

[0078] The sleeve 510 and the movable rod 520 cooperate mainly to guide the upward and downward movement of the movable plate 12012 . Embodiment 2

[0079] A sintering method using a sintering device for manufacturing a vapor chamber comprises the following steps:

[0081] Put the material to be sintered between the upper graphite pad 12018 and the lower graphite pad 12019, close the door 1301 of the sealing box 130 and close the box body 110;

[0082] S2, sintering;

[0083] Hot pressing of sintered materials;

[0084] S2.1, sintering stage;

[0085] The movable plate 12012 is driven by the hydraulic system 12011 to move downward, so that the upper transfer copper plate 12013, the conductive copper column 12015, the upper electrode copper plate 12016 and the upper graphite pad 12018 move downward. At this time, the hot pressing workbench 1201 is powered on to perform hot pressing on the material to be sintered.

[0086] S2.2, observation phase;

[0087] During the sintering process, the sintering condition inside the sealed box 130 can be observed through the observation window 1302, and the temperature can also be observed through the temperature measuring device 430;

[0088] S2.3, cooling stage;

[0089] When the hot pressing stage is about to end and when the hot pressing is finished, the hot pressing assembly and the sintered material under the hot pressing assembly are cooled. When the hydraulic system 12011 is pressed down, the relative distance between the movable plate 12012 and the sealing box 130 becomes smaller, so the rack 1401 connected to the sealing box 130 drives the main gear 1402 to rotate, and indirectly drives the adjustment plate 320 to rotate. The adjustment plate 320 is driven by the lifting and lowering of the hot pressing assembly to adjust the size of the aggregation channel 240 to adjust the flow rate of the cooling water, and different levels of cooling are performed. In addition, the first water cooling channel 210 will also cool the upper transfer copper plate 12013 and the lower transfer copper plate 12014;
