Description

Technical Field

[0001] The utility model belongs to the technical field of liquid cooling cabinets, and in particular relates to an air-liquid integrated machine. Background Art

[0002] In the field of liquid cooling, immersion liquid cooling is one of the common liquid cooling methods.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.10 As shown, an air-liquid integrated machine includes a liquid cooling cabinet, a liquid inlet pipe 101, a liquid outlet pipe 102, a circulating liquid pump 103 arranged in the liquid cooling cabinet, and an air cooler 104 arranged in the liquid cooling cabinet, and also includes a cooling fan 105 for blowing air to the air cooler 104 to dissipate heat;

[0030] The liquid cooling cabinet comprises a body 2 with an opening at the upper end and a cover 3 for covering the opening at the upper end of the body 2, the cover 3 is hinged to the body 2, a vertical partition 201 is provided in the body 2, the vertical partition 201 divides the inside of the body 2 into a liquid cooling chamber 2.1 and a heat dissipation chamber 2.2, a bracket 202 matching the liquid cooling server is provided in the liquid cooling chamber 2.1, a circulating liquid pump 103, an air cooler 104 and a cooling fan 105 are all located in the heat dissipation chamber 2.2, and a heat dissipation hole group structure connected to the heat dissipation chamber 2.2 is provided on the body 2;

[0031] The vertical partition 201 is provided with a side overflow port 201a and an overflow box 4, and the overflow box 4 is provided with a box cross plate 401, which divides the interior of the overflow box 4 into an upper overflow chamber 4.1 and a lower focusing chamber 4.2. One side of the upper overflow chamber 4.1 is connected to the overflow port, and the box cross plate 401 is provided with a plurality of liquid drop holes 401a;

[0032] The liquid outlet end of the circulating liquid pump 103, the liquid inlet main pipe 101, the liquid cooling chamber 2.1, the side overflow port 201a and the upper overflow chamber 4.1 are connected in sequence, the lower focusing chamber 4.2, the liquid outlet main pipe 102, the liquid inlet end of the air cooler 104, the liquid outlet end of the air cooler 104 and the liquid inlet end of the circulating liquid pump 103 are connected in sequence, the vertical distance between the highest point of the liquid cooling server installed on the bracket 202 and the lowest point of the side overflow port 201a is 2 cm, the highest point of the side overflow port 201a, the lowest point of the side overflow port 201a and the liquid cooling server installed on the bracket 202 are arranged in sequence from top to bottom, and the height of the lowest point of the side overflow port 201a is consistent with the height of the top surface of the box cross plate 401.

[0033] In this solution, one or more liquid-cooled servers are installed on the rack 202. The coolant is filled in the liquid cooling chamber 2.1, and the circulating liquid pump 103, the liquid inlet pipe 101, the liquid outlet pipe 102, the internal pipes of the air cooler 104, etc. are all filled with coolant. Among them, the coolant level in the liquid cooling chamber 2.1 should be higher than the liquid cooling server, because the immersion liquid cooling should ensure that the liquid cooling server is immersed in the coolant. The coolant level should be slightly higher than the liquid cooling server, but not just a little higher than the liquid cooling server (such as 0.5cm), because once the coolant level shakes (such as the vibration of the circulating liquid pump 103 causing the liquid level to shake), it is easy for the top of the liquid cooling server to be exposed outside the coolant, resulting in poor heat dissipation effect and affecting the normal operation of the server. Comprehensively considered, the coolant level should be higher than the liquid cooling server by more than 2cm and less than 4cm.

[0034] The circulating pump 103 delivers the coolant into the liquid cooling chamber 2.1 through the liquid inlet pipe 101. The coolant moves from bottom to top in the liquid cooling chamber 2.1. When passing through each liquid cooling server, it absorbs a large amount of heat. The coolant after absorbing heat cannot stay above the liquid cooling server for a long time (the vertical distance between the highest point of the liquid cooling server installed on the rack 202 and the lowest point of the side overflow port 201a is only 2 cm). The coolant above the lowest point of the side overflow port 201a will enter the lower flow collecting chamber 4.2 through the side overflow port 201a, the upper overflow chamber 4.1, and each drop hole 401a, and then pass through the liquid outlet pipe 102 and the air cooler 104, and finally return to the circulating pump 103. The coolant after absorbing heat can be cooled and dissipated when passing through the air cooler 104. In addition, the cooling fan 105 blows air to the air cooler 104, which can accelerate the cooling, so that the temperature of the coolant returning to the circulating pump 103 can be relatively lower.

[0035] For the inside of the liquid cooling chamber 2.1, the coolant flow capacity at each position is different. The coolant flow capacity is strong in the area close to the liquid inlet position of the liquid cooling chamber 2.1 and the area close to the liquid outlet position of the liquid cooling chamber 2.1. Therefore, the liquid-cooled servers close to these positions can usually dissipate heat better. If the liquid-cooled server is in an area far away from the liquid outlet position of the liquid cooling chamber 2.1, the coolant flow capacity near the liquid-cooled server is relatively weak, and it is easier to accumulate heat. In addition, the coolant after absorbing heat has a poor cooling capacity for the liquid-cooled server. If it stays above the liquid-cooled server too much and for too long, it will also affect the overall heat dissipation effect. In view of this, in the present solution, a side overflow port 201a and an overflow box 4 structure are provided, and "the highest point of the liquid-cooled server is only 2 cm lower than the lowest point of the side overflow port 201a". In this way, after the coolant passes through the liquid-cooled server from bottom to top and absorbs heat, it cannot stay above the liquid-cooled server for a long time (if it exceeds the lowest point of the side overflow port 201a, it will quickly flow away from the side overflow port 201a and then go to the air cooler 104 as soon as possible, and it is not easy to accumulate above or near the liquid-cooled server for a long time). In this way, the overall heat dissipation effect is improved without substantially increasing the energy consumption of the circulating liquid pump 103 and the cooling fan 105.

[0036] like Figure 4 , Figure 6 , Figure 8 As shown, the liquid cooling chamber 2.1 is provided with a transverse partition 5, which divides the liquid cooling chamber 2.1 into an upper liquid chamber 2.1a and a lower liquid chamber 2.1b. The transverse partition 5 includes a transverse partition plate 501 and a liquid inlet pipe 502 connected to the liquid inlet main pipe 101. The liquid inlet pipe 502 is provided with a plurality of liquid inlet sub-holes 502a arranged in sequence along the length direction of the liquid inlet pipe 502. The liquid inlet sub-holes 502a are connected to the lower liquid chamber 2.1b, and the transverse partition plate 501 is provided with a liquid equalizing hole group.

[0037] The liquid balancing hole group includes multiple groups of horizontal liquid holes evenly arranged in sequence along the left-right direction of the liquid cooling cabinet. In one horizontal liquid hole, the horizontal liquid hole includes multiple small liquid holes 501a evenly arranged in sequence along the front-back direction of the liquid cooling cabinet.

[0038] The upper liquid chamber 2.1a of the liquid cooling chamber 2.1 is supplied with (cold) cooling liquid in a multi-hole evenly distributed manner, so that the temperature difference of the cooling liquid near each liquid cooling server is relatively small, further improving the uniformity of heat dissipation and ensuring better overall cooling and heat dissipation effect.

[0039] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10As shown, the overflow box 4 is provided with an adjusting overflow hole 4a above the box cross plate 401 on the side wall, the vertical distance between the highest point of the liquid cooling server installed on the bracket 202 and the lowest point of the adjusting overflow hole 4a is 4 cm, the heat dissipation cavity 2.2 is provided with an adjusting pot box 6 slidably connected to the fuselage 2, the sliding direction of the adjusting pot box 6 is vertical, and the adjusting pot box 6 is provided with a pot box hole 6a on the side wall adjacent to the overflow box 4, the lowest point of the pot box hole 6a is at the same height as the bottom of the adjusting pot box 6, the adjusting overflow hole 4a is connected to the pot box hole 6a through a hose 601, the hose 601 is located between the adjusting pot box 6 and the overflow box 4, and the top of the adjusting pot box 6 is connected to the bottom of the cover 3 through a cable 602;

[0040] When the cover 3 covers the upper opening of the fuselage 2: the height of the lowest point of the adjustment overflow hole 4a is higher than the height of the highest point of the adjustment kettle box 6, and the height of any point on the inner wall of the hose 601 is higher than the height of the lowest point of the kettle box hole 6a;

[0041] When the machine cover 3 is in the open state and the angle between the machine cover 3 and the horizontal plane is greater than or equal to 60 degrees, the height of the lowest point of the kettle box 6 is adjusted to be higher than the height of the highest point of the adjustment overflow hole 4a, and the height of any point on the inner wall of the hose 601 is higher than the height of the lowest point of the adjustment overflow hole 4a.

[0042] The cover 3 is hinged to the body 2. When the number of liquid-cooled servers in the liquid-cooling chamber 2.1 needs to be increased or decreased, the cover 3 can be directly opened for operation. Regarding how to position the cover 3 after it is opened: Example 1: The cover 3 can be hinged to the body 2 through a self-locking hinge, so that the cover 3 can remain in the open state after it is opened; Example 2: A conventional self-locking support structure such as a gas spring can be set between the cover 3 and the body 2, so that the cover 3 can remain in the open state after it is opened; Example 3: After opening the cover 3, the cover 3 can be directly supported by a support rod, so that the cover 3 can remain in the open state after it is opened.

[0043] As described above, in the present invention, in order to ensure that the cooling liquid after absorbing heat does not stay above the liquid-cooled server in large quantities and for a long time, the cooling liquid level in the liquid-cooled chamber 2.1 is only 2 to 4 cm higher than the liquid-cooled server. When there is no liquid-cooled server in the liquid-cooled chamber 2.1, the liquid level in the liquid-cooled chamber 2.1 is equal to or slightly lower than the height of the lowest point of the regulating overflow hole 4a. When the number of liquid-cooled servers in the liquid-cooled chamber 2.1 increases, the liquid level in the liquid-cooled chamber 2.1 will rise. In this solution, after the cover 3 is closed (when the cover 3 covers the opening at the upper end of the fuselage 2), since "the lowest point of the regulating overflow hole 4a is higher than the highest point of the regulating pot box 6, and the height of any point on the inner wall of the hose 601 is higher than the lowest point of the pot box hole 6a", the coolant that is higher than the regulating overflow hole 4a will enter the regulating pot box 6 through the regulating overflow hole 4a and the hose 601; in this way, no matter how much the number of liquid-cooled servers in the liquid-cooling chamber 2.1 increases, it can be ensured that the liquid level is within the set range (not higher than the lowest point of the regulating overflow hole 4a). Under normal circumstances, when the number of liquid-cooled servers in the liquid-cooling chamber 2.1 decreases, the liquid level in the liquid-cooling chamber 2.1 will decrease, but in this solution, when the number of liquid-cooled servers in the liquid-cooling chamber 2.1 is to be reduced, the cover 3 is opened (such as Figure 6 , Figure 7 As shown, the angle between the machine cover 3 and the horizontal plane is 60 degrees. It is also possible to select an angle greater than 60 degrees between the machine cover 3 and the horizontal plane according to actual conditions and needs). At this time, "the height of the lowest point of the adjusting pot box 6 is higher than the height of the highest point of the adjusting overflow hole 4a, and the height of any point on the inner wall of the hose 601 is higher than the height of the lowest point of the adjusting overflow hole 4a", and the coolant in the adjusting pot box 6 is all or almost all entered into the liquid cooling chamber 2.1 (the liquid level in the liquid cooling chamber 2.1 rises), and then, a part of the liquid-cooled server in the liquid cooling chamber 2.1 is removed as needed, and the machine cover 3 is closed. The coolant that is higher than the adjusting overflow hole 4a will enter the adjusting pot box 6 through the adjusting overflow hole 4a and the hose 601. In this way, the liquid level can be guaranteed to be within the set range.

[0044] like Figure 6 , Figure 7 As shown, the overflow box 4 is provided with a support plate 603 for supporting the regulating pot box 6. When the machine cover 3 covers the opening at the upper end of the fuselage 2, the top surface of the support plate 603 contacts the bottom surface of the regulating pot box 6. A one-way exhaust valve is provided on the top of the regulating pot box 6. The one-way exhaust valve can pass from the inside of the regulating pot box 6 through the one-way exhaust valve to the outside of the regulating pot box 6.

[0045] The support plate 603 can support the regulating pot box 6, reduce the burden of the cable 602, and improve stability. The one-way exhaust valve is conducive to balancing the air pressure in the regulating pot box 6 when the coolant enters the regulating pot box 6.

[0046] like Figure 1 , Figure 2 , Figure 4As shown, the fuselage 2 includes a front panel 2a, a rear panel 2b, a left panel 2c, a right panel 2d and a bottom panel 2e, the front panel 2a is parallel to the rear panel 2b, the left panel 2c is parallel to the right panel 2d, and the heat dissipation hole group structure includes a plurality of front heat dissipation holes 701 arranged on the front panel 2a, a plurality of left heat dissipation holes 702 arranged on the left panel 2c and a plurality of right heat dissipation holes 703 arranged on the right panel 2d.

[0047] The front plate 2a is parallel to the left and right direction of the liquid cooling cabinet, and the left plate 2c is parallel to the front and rear direction of the liquid cooling cabinet. The cover 3 is hinged to the front plate 2a or the cover 3 is hinged to the rear plate 2b. Each front heat dissipation hole 701, each left heat dissipation hole 702, and each right heat dissipation hole 703 can assist ventilation and heat dissipation.

[0048] The above is a detailed introduction to the embodiments of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for technicians in this field, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
