Description

Technical Field

[0001] This application relates to the technical field of heat dissipation devices, and particularly to a liquid cooling heat dissipation and filtration device. Background Art

[0002] During the sintering process of process materials such as graphite, in order to ensure product quality, the sintering furnace must be strictly evacuated. Traditional sintering furnaces often face a series of technical challenges during the evacuation process. First, the air in the furnace will cause oxidation of the graphite parts at high temperatures, thereby affecting the overall performance of the product. Therefore, in order to reduce oxidation, the sintering furnace usually needs to be evacuated to below 10 Pa. However, even in such a vacuum environment, when the temperature in the furnace reaches a certain range, gaseous colloidal substances may still be generated in the hot atmosphere in the furnace. These substances cause extremely serious pollution to the materials, not only affecting product quality but also possibly resulting in huge economic losses. The most direct economic loss is that the existing evacuation system is easily damaged due to inhaling gaseous colloidal substances during the sintering process of materials such as graphite.

[0015] 1.

[0018] 4. By setting the air blocking strip, on the one hand, it can slow down the passage of gas and increase the cooling time of the gas. On the other hand, it can block the already condensed gel.

[0019] 5. Divide the liquid accommodation cavity into an annular liquid accommodation cavity and a bottom liquid accommodation cavity, which can slow down the outflow of the liquid and enable the liquid to fully exchange heat.

[0020] 6. By setting a number of flow blocking strips arranged at intervals and staggered, the coolant flows in a serpentine shape, increasing the heat exchange time of the liquid.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings of the present application. Obviously, the described embodiments of the present application are only partial embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0029] With reference to Figure 1 and Figure 2 , a liquid-cooled heat dissipation and filtration device includes a liquid-cooled cylinder body 1 capable of introducing and discharging gas and a liquid-cooling mechanism 2 disposed inside the liquid-cooled cylinder body 1 for heat exchange between liquid and surrounding gas. The liquid-cooled cylinder body 1 includes an outer cylinder body 11 and an inner cylinder body 12 disposed inside the outer cylinder body 11. A liquid accommodation cavity is formed between the outer cylinder body 11 and the inner cylinder body 12, and a coolant is provided in the liquid accommodation cavity. A cylinder cover 3 movably connected to the liquid-cooled cylinder body 1 is provided at the cylinder opening of the liquid-cooled cylinder body 1;

[0030] The liquid-cooling mechanism 2 includes two liquid-cooling components and at least one heat dissipation blocking piece 25. Each liquid-cooling component includes a fixing plate 21 having the same height as the inner cylinder body 12 and a serpentine cooling pipe 22. The fixing plate 21 is vertically disposed inside the inner cylinder body 12 and fixedly connected to the bottom of the inner cylinder body 12. There is a gap between any side edge of the fixing plate 21 in the vertical direction and the cylinder wall of the inner cylinder body 12. The cooling pipe 22 is fixedly provided on the installation side of the fixing plate 21, and the heat sink 23 is fixedly provided on the side opposite to the installation side of the fixing plate 21. A coolant is provided in the cooling pipe 22;

[0031] The installation sides of the two liquid-cooling components are oppositely arranged, and an interval area 24 is formed between the two liquid-cooling components. The heat dissipation blocking piece 25 is vertically disposed in the interval area 24 and fixedly connected to the bottom of the inner cylinder body 12. The heat dissipation blocking piece 25 can prevent gas from passing through the interval area 24.

[0032] The heat dissipation barrier 25 blocks gas from passing through the spacer region 24. It can be understood that: the gas does not pass through the spacer region 24; or it can be understood that: there is a small gap between the heat dissipation barrier 25 and the fixing plate 21, and the gas enters the spacer region 24 through this small gap and flows out from the small gaps between other heat dissipation barriers 25 and the fixing plate 21.

[0033] Referring to Figure 2 , two heat dissipation barriers 25 are provided in the spacer region 24, namely a first heat dissipation barrier and a second heat dissipation barrier. The first heat dissipation barrier is close to the wall of the inner cylinder 12, and the second heat dissipation barrier is away from the first heat dissipation barrier.

[0034] Referring to Figure 2 , the liquid cooling assembly further includes at least one air blocking strip 26 fixedly connected to the inner cylinder 12, and a gas filtering channel is formed between the air blocking strip 26 and the fixing plate 21.

[0035] Referring to Figure 1 , both ends of the cooling pipe 22 pass through the cylinder cover 3. One end of the cooling pipe 22 is used to introduce the coolant, and the other end of the cooling pipe 22 is used to discharge the coolant.

[0036] Referring to Figure 1 and Figure 2 , the outer cylinder 11 is provided with at least two liquid diversion ports communicating with the liquid containing cavity.

[0037] Referring to Figure 2 and Figure 3 , the bottom surface of the inner cylinder 12 extends outward to the wall of the outer cylinder 11 to form a partition part 121. The partition part 121 divides the liquid containing cavity. An annular liquid containing cavity 13 is formed above the partition part 121, and a bottom liquid containing cavity 14 is formed below the partition part 121. The partition part 121 is provided with a circulation port 122. The annular liquid containing cavity 13 and the bottom liquid containing cavity 14 are communicated through the circulation port 122. The wall of the outer cylinder 11 is provided with a liquid inlet 111 communicating with the annular liquid containing cavity 13, and the bottom of the outer cylinder 11 is provided with a liquid outlet 112 communicating with the bottom liquid containing cavity 14.

[0038] Referring to Figure 4 , the annular liquid containing cavity 13 is provided with a plurality of flow blocking strips 15 arranged at intervals and staggered, and the bottom liquid containing cavity 14 is provided with a plurality of flow blocking strips 15 arranged at intervals and staggered.

[0039] Referring to Figure 1 and Figure 2, the cooling pipes 22 of the two liquid cooling components are interconnected. In this embodiment, the two cooling pipes 22 are connected by a connecting pipe to make the two cooling pipes 22 interconnected. Additionally, the two cooling pipes 22 can also be directly connected and regarded as two parts of a single pipe.

[0040] When the vacuum pumping system is operating, high-temperature gas enters the liquid cooling cylinder 1 through a gas guiding part 10. At this time, the coolant is introduced into the cooling pipe 22. Since the cooling pipe 22 is serpentine, the coolant flows in a serpentine manner and exchanges heat with the fixing plate 21 sufficiently, so that the fixing plate 21 can quickly absorb the heat on the heat sink 25, and finally achieve the effect of quickly cooling the gas in the inner cylinder 12. New coolant is continuously introduced into the cooling pipe 22 to improve the heat exchange efficiency, and the coolant after absorbing heat flows out of the cooling pipe 22, taking the internal heat out.

[0041] While the liquid cooling mechanism 2 cools the high-temperature gas, the liquid inlet 111 introduces low-temperature liquid. The low-temperature liquid sequentially enters the annular liquid accommodating cavity 13 and the bottom liquid accommodating cavity 14. The low-temperature liquid can cool the inner cylinder 12, that is, it can exchange heat with the high-temperature gas in the inner cylinder 12 to achieve the cooling of the high-temperature gas.

[0042] After the high-temperature gas is cooled, the gaseous colloid brought in by the gas cools and condenses. The condensed colloid is likely to fall to the bottom of the liquid cooling cylinder. The cooled gas enters the vacuum pumping system through another gas guiding part 10. The vacuum pumping system inhaling the cooled gas can reduce the inhalation of the gaseous colloid.

[0043] After the high-temperature gas enters the inner cylinder 12, due to the blocking of the air-blocking strip 26, it can only slowly pass through the air filtration channel, increasing the residence time of the high-temperature gas, making the high-temperature gas exchange heat and cool sufficiently. Additionally, since the air filtration channel is relatively narrow, it can also block the condensed colloid, playing a filtering role.

[0044] In summary, the liquid cooling and heat dissipation filtering device of the present application can enable the vacuum pumping system to inhale the cooled gas, thereby reducing the inhalation of the gaseous colloid. Therefore, the liquid cooling and heat dissipation filtering device of the present application can solve the problem that the vacuum pumping system is easily damaged due to inhaling too much gaseous colloid.

[0045] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0046] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of this application and its equivalent technologies, this application also intends to include these changes and modifications.
