Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling, in particular to a drying device and a liquid cooling cabinet. Background Art

[0002] With the rapid development of cloud computing, the requirements for computing performance are getting higher and higher. While server performance is improving, power consumption is rising rapidly, and cabinet power consumption is increasing exponentially. Data shows that the power density of data center cabinets has increased 15 times in the past decade. In the past, the power consumption of a rack was generally 1.5-2kW, but now it is as high as 20-30kW in some areas. Existing servers and data centers use air-conditioning cooling, which uses air conditioning to send cold air into the cabinet loaded with servers to cool the electronic devices. However, with the steady increase in power density, the cooling capacity of air-conditioning cooling is also approaching its limit and cannot meet the cooling needs. Therefore, it is necessary to provide a new cooling method to cool electronic devices, so liquid cooling technology has emerged. The advantage of liquid cooling technology is that its heat transfer medium has higher specific heat capacity and thermal conductivity, which can better solve the thermal management of battery systems than air cooling.

[0003] The performance of the coolant is the key to heat dissipation. However, during the operation of the liquid cooling system, the coolant will inevitably come into contact with the air, causing moisture in the air to dissolve into the coolant. The presence of moisture not only reduces the heat dissipation performance of the coolant, but may also cause corrosion and short circuit problems in the equipment, affecting the reliability and life of the system. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model provides a drying device and a liquid cooling cabinet, which have the advantages of being able to remove moisture in the cooling liquid in time and being environmentally friendly.

An inner shell is also placed in the cavity, and the inner shell is filled with a water-absorbing desiccant. When the coolant flows through the inner shell, it generally enters the inner shell from the opening at the upper part of the inner shell, and then flows out from the opening at the lower part of the inner shell under the action of gravity. The multiple openings constitute multiple coolant channels. In this process, moisture will be effectively absorbed by the water-absorbing desiccant, thereby keeping the coolant in a dry state. The drying device can not only remove excess moisture in the coolant in real time and efficiently, but also maintain the smooth circulation of the coolant, thereby ensuring the stable operation of the liquid cooling system, and the drying method is environmentally friendly and non-toxic.

[0009] Optionally, a handle extending toward the liquid inlet is provided on the top surface of the inner shell.

[0010] Optionally, the inner shell includes a top wall, a bottom wall, and a vertical wall arranged between the top wall and the bottom wall, and the handle is connected to the outer surface of the top wall; the opening is provided on at least the top wall and the vertical wall.

[0011] Optionally, the liquid inlet structure is provided with a filter screen covering the liquid inlet, and at least one handle is provided on the filter screen.

[0012] Optionally, a positioning step protruding toward the inner side wall of the shell is formed at the bottom of the filter screen, and a boss cooperating with the positioning step is formed on the inner side wall of the shell.

The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0027] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0028] Example:

[0029] like Figures 1 to 4 As shown, a drying device comprises a shell 11, the shell 11 has a cavity 111 for containing a coolant, a liquid inlet 1111 for the coolant to flow into the top of the cavity 111 is provided, and a liquid outlet 1112 for the coolant to be discharged is provided at the bottom of the cavity 111; an inner shell 12 is also provided in the cavity 111, and the inner shell 12 is filled with a water-absorbing desiccant, such as Figure 5 As shown, the inner shell 12 is provided with a plurality of openings 121 penetrating the inner shell 12 along the thickness direction.

[0030] In this embodiment, the drying device 1 is used to ensure that the coolant in the liquid cooling system is dry and clean. It can effectively remove excess water and impurities in the coolant to ensure the normal operation of the liquid cooling system. Specifically, the outer shell 11 is the main body of the device, and a cavity 111 for accommodating the coolant is formed in the outer shell 11. The top of the cavity 111 is provided with a liquid inlet 1111 for introducing the coolant, and the bottom of the cavity 111 is provided with a liquid outlet 1112 for discharging the coolant, so as to facilitate the recycling of the coolant. The inner shell 12 is also placed in the cavity 111, and the inner shell 12 is filled with a water-absorbing desiccant. When the coolant flows through the inner shell 12, it generally enters the inner shell 12 from the opening 121 at the upper part of the inner shell 12, and then flows out from the opening 121 at the lower part of the inner shell 12 under the action of gravity. The multiple openings 121 constitute multiple coolant channels. In this process, the moisture will be effectively absorbed by the water-absorbing desiccant, thereby maintaining the dry state of the coolant. The drying device 1 can not only efficiently remove excess water from the coolant, but also maintain smooth circulation of the coolant, thereby ensuring stable operation of the liquid cooling system and extending the service life of the equipment. At the same time, the device has a simple structure, is easy to operate, and has low maintenance costs, and is a very practical auxiliary equipment for the liquid cooling system.

[0031] The shape of the outer shell 11 is a rectangular parallelepiped. The rectangular parallelepiped outer shell 11 usually has a larger volume of the cavity 111, which can accommodate more coolant, and its regular shape is also convenient for installation and positioning. In addition, the rectangular parallelepiped outer shell 11 can also be modularly designed as needed to facilitate expansion and upgrading. Of course, in other embodiments, the shape of the outer shell 11 can also be a cube or a cylinder. The cylindrical outer shell 11 has good structural strength and stability and is easy to process and manufacture. In another embodiment, according to a specific installation environment and space limitations, the shape of the outer shell 11 can also be irregular. The irregularly shaped outer shell 11 can better adapt to the layout requirements in the actual scene and achieve more efficient space utilization. In this embodiment, the shape of the inner shell 12 is a rectangular parallelepiped. In other embodiments, the shape of the inner shell 12 can also be configured as a cube, a cylinder or a special shape.

[0032] The water-absorbing desiccant can be calcium chloride desiccant, silica gel desiccant, mineral desiccant, fiber desiccant or activated alumina, etc. Different desiccants may have different applicability to different substances and environments. Therefore, when selecting and using desiccant, it is necessary to evaluate and select according to the specific situation.

[0033] In addition, a drain port for draining the coolant is also provided at the bottom of the side of the housing 11 . The drain port is convenient for releasing more coolant when repairing or replacing the water-absorbing desiccant. Therefore, the drain port 1113 is located lower than the liquid outlet 1112 .

[0034] The inner shell 12 is detachably disposed on the bottom surface of the cavity 111 .

[0035] The shape of the inner shell 12 is adapted to the shape of the cavity 111, and the cross-sectional area of ​​the inner shell 12 is slightly smaller than or consistent with the cross-sectional area of ​​the cavity 111, so that as much coolant as possible falls into the inner shell 12, that is, the desiccant in the inner shell 12 can dry more coolant. In addition, the stability and positioning accuracy of the inner shell 12 in the cavity 111 can also be guaranteed. In this embodiment, the inner shell 12 is placed on the bottom surface of the cavity 111 in a detachable manner, so that the inner shell 12 can be easily removed from the bottom surface of the cavity 111, which is convenient for replacing the water-absorbing desiccant. In other embodiments, in order to realize the detachable design of the inner shell 12 and the cavity 111, a connection structure such as a snap, a thread, or a magnetic adsorption can be used between the inner shell 12 and the cavity 111 to ensure the stability of the inner shell 12 under normal working conditions and realize the disassembly and installation of the inner shell 12. In addition, the coolant in this embodiment is cooling oil, and the density of water is greater than that of oil, so the water in the cavity 111 will automatically settle to the bottom of the cavity 111, and the inner shell 12 is also arranged at the bottom of the cavity 111, so that the desiccant can absorb the water. This design utilizes the principle of physical separation instead of chemical separation, thereby reducing the impact of the treatment process on the cooling oil itself.

[0036] A handle 122 extending toward the liquid inlet 1111 is provided on the top surface of the inner shell 12 .

[0037] In this embodiment, the handle 122 makes it easy to take the inner shell 12 out of the cavity 111. The operator can easily move the inner shell 12 by grabbing the handle 122 without directly touching other parts of the inner shell 12, which helps to reduce the risk of contamination and damage. In addition, by controlling the height of the handle 122 below the liquid inlet 1111, it can ensure that the drying device 1 is more neat and uniform in appearance, and also help to reduce the occupied space. In the process of liquid flowing into the cavity 111, the handle 122 will not hinder the flow of the liquid, ensuring the smooth entry of the liquid and avoiding the obstruction or splashing of the liquid flow due to the presence of the handle 122.

[0038] The inner shell 12 includes a top wall, a bottom wall and a vertical wall disposed between the top wall and the bottom wall. The handle 122 is connected to the outer surface of the top wall. At least the top wall and the vertical wall are provided with the opening 121.

[0039] A filter screen 13 covering the opening is disposed at the liquid inlet 1111 , and at least one handle is provided on the filter screen 13 .

[0040] In this embodiment, the liquid inlet 1111 is constructed as an opening with a length consistent with the shell 11, which can ensure that the coolant has a larger inlet area when flowing in, thereby accelerating the inflow speed of the coolant, improving the working efficiency of the drying device 1, and reducing the splashing or overflow of the coolant. The filter screen 13 covering the opening plays a role of filtering and protection. The filter screen 13 can intercept impurities, particles or other unnecessary substances in the coolant, thereby protecting the normal operation of the liquid cooling system and extending its service life. In addition, the filter screen 13 with different apertures can be replaced according to different types of coolants to achieve different filtering accuracies.

[0041] A positioning step protruding toward the inner wall of the shell 11 is formed at the bottom of the filter screen 13 , and a boss cooperating with the positioning step is formed on the inner wall of the shell 11 .

[0042] In this embodiment, by abutting the positioning step against the boss, the filter 13 can be firmly installed on the inner wall of the housing 11 and is not easy to loosen or fall off. This installation method ensures that the filter 13 can maintain a stable position when the liquid cooling system is running, and prevents displacement due to vibration or impact. When the filter 13 needs to be cleaned or replaced, the cooperation of the positioning step and the boss makes the disassembly process just as simple and quick. The operator only needs to lift the filter 13 to remove it from the inner wall of the housing 11, without using additional tools or performing complicated operations.

[0043] The side wall of the shell 11 has at least one reinforcing rib 112 extending along the height direction of the shell 11 . The reinforcing rib 112 is formed by bending the side wall of the shell 11 toward the vertical axis of the side wall of the shell 11 .

[0044] In this embodiment, there are two reinforcing ribs 112 on the side wall of the housing 11. In other embodiments, the number of reinforcing ribs 112 can also be 3, 4 or 5. The presence of the reinforcing ribs 112 can significantly improve the rigidity and impact resistance of the housing 11. At the same time, the reinforcing ribs 112 can effectively disperse and resist the external pressure or impact force on the housing 11, prevent the housing 11 from being deformed or broken, protect the components and structures inside the housing 11, and ensure that the device can still operate normally in harsh environments.

[0045] A plurality of liquid level indicating lines 113 are formed on the outer wall surface of the housing 11 .

[0046] In this embodiment, the liquid level indicator line 113 serves as an indicator and a marker, helping the user to intuitively understand the liquid level in the liquid cooling system (such as in a liquid cooling cabinet) where the housing 11 is located, and to quickly determine whether the liquid in the device has reached a predetermined level without using a special measuring tool. Different liquid level indicator lines 113 may represent different operating states or liquid quantities, such as the lowest working liquid level, the highest working liquid level, the safe liquid level, etc., so that the user can adjust the amount of coolant added or the operating method according to actual needs.

[0047] This embodiment further provides a liquid-cooling cabinet, comprising a chamber 2 for containing cooling liquid and at least one electronic information device, wherein the chamber 2 is provided with the aforementioned drying device 1 .

[0048] The liquid-cooled cabinet provided in this embodiment directly dissipates heat from the inside of the cabinet through a liquid cooling medium, thereby greatly improving the heat dissipation efficiency. The main components of the liquid-cooled cabinet include a chamber 2 for containing a coolant and at least one electronic information device, and a drying device 1 arranged in the chamber 2. The drying device 1 arranged in the chamber 2 can effectively prevent the condensation of water in the coolant, thereby avoiding potential damage to the electronic information equipment. In addition, the top surface of the drying device 1 does not exceed the top surface of the chamber 2. When the liquid level of the coolant exceeds the top surface of the outer shell 11 of the drying device 1, the coolant will enter the cavity 111 of the outer shell 11, that is, the drying device 1 is also equivalent to the overflow device of the liquid-cooled cabinet, which is used to prevent the liquid in the cabinet from exceeding the safety limit and leaking.

[0049] The bottom surface of the housing 11 is fixed to the bottom surface of the chamber 2 .

[0050] The bottom surface of the shell 11 is fixed to the bottom surface of the chamber 2 by welding or the like, thereby ensuring a firm connection between the shell 11 and the chamber 2, so that the drying device 1 is not easily displaced or shaken inside the cabinet.

[0051] like Figure 6 As shown, the liquid-cooled cabinet includes a liquid supply pipeline 3 , and the liquid outlet 1112 is connected to the liquid supply pipeline 3 .

[0052] The liquid supply pipeline 3 is a channel for the circulation of the coolant, which is responsible for delivering the coolant to various key parts in the cabinet to achieve effective cooling of the electronic information equipment. The liquid outlet 1112 is connected to the liquid supply pipeline 3 to allow the dried coolant to enter the liquid supply pipeline 3 again to continue cooling the electronic information equipment.

[0053] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
