Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled cabinet technology, and specifically to a liquid-cooled cabinet. Background Technology

[0002] Liquid-cooled cabinets are a technology used for cooling data centers or other electronic equipment, widely applied to heat dissipation of high-power-density devices. Compared to traditional air-cooled systems, liquid cooling systems offer higher heat exchange efficiency, effectively managing large amounts of heat within a smaller space and reducing the impact of temperature rise on equipment performance. The coolant flow field design within the liquid-cooled cabinet is crucial to the overall system efficiency, stability, and heat dissipation effect. A good flow field design can effectively improve the coolant's flow efficiency and heat dissipation capacity.

[0003] In related technologies, coolants are typically chosen as liquids with good thermal conductivity and moderate viscosity. The choice of coolant directly affects the flow field design, because different liquids have different physical properties such as viscosity, density, and thermal conductivity, resulting in variations in flow patterns and heat dissipation effects. For coolant flow channels, when the containment space is used to hold the coolant and cooling equipment, the design typically involves the coolant entering the containment space through a pipe at the bottom and then exiting through an opening at the top. The exiting coolant, which is at a relatively high temperature, is then cooled by a cooling fan or similar means before being returned to the containment space.

[0004] Existing technologies have poor cooling effects, inconsistent cooling efficiency, and cannot achieve uniform heat dissipation within the cooling space. Utility Model Content

[0005] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides a liquid-cooled cabinet, which has the advantages of improving the coolant flow field design and making the coolant flow more uniform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A liquid-cooled cabinet includes a shell and an inner liner disposed inside the shell. The inner liner has an opening and a coolant inlet is formed on the bottom wall of the inner liner. The inner liner has a total accommodating space. The liquid-cooled cabinet is characterized in that it further includes a baffle and at least one partition, both of which are disposed inside the inner liner. The baffle is opposite to and spaced apart from the bottom wall of the inner liner to divide the total accommodating space into a liquid inlet space and a cooling space. The baffle has a plurality of liquid inlet holes extending through it along its thickness direction, which connect the liquid inlet space and the cooling space. The partition is disposed in the cooling space and divides the cooling space into a plurality of sub-cooling spaces. The sub-cooling space is filled with coolant. The equipment to be cooled is placed in the coolant and placed on a baffle. The coolant enters the inlet space of the inner tank through the coolant inlet, and then enters the cooling space through the inlet hole connecting the inlet space and the cooling space to cool the equipment to be cooled. After absorbing heat, it flows out from the top of the cooling space. Through the above arrangement, the equipment to be cooled is cooled in multiple sub-cooling spaces, which has the advantages of improving cooling efficiency and cooling uniformity.

[0008] Optionally, the liquid-cooled cabinet further includes a mounting bracket, which is supported between the baffle and the bottom wall of the inner liner to form a gap between the baffle and the bottom wall of the inner liner. The mounting bracket provides support for the baffle, creating a liquid inlet space between the baffle and the bottom wall of the inner liner, thereby enabling the coolant to enter each sub-cooling space evenly and improving the uniformity of the cooling effect.

[0009] Optionally, the mounting bracket includes an integrally connected support portion and a load-bearing portion. The load-bearing portion is fitted against the bottom wall surface of the inner liner facing inwards. The support portion is fixed in contact with the baffle, and a non-zero angle is formed between the support portion and the bottom wall of the inner liner. The fixed fit between the load-bearing portion and the bottom wall of the inner liner increases the contact area and improves the stability of the mounting bracket. The support portion supports the baffle, and the non-zero angle between the support portion and the bottom wall of the inner liner increases the size of the inlet space, allowing for a more uniform distribution of coolant when it enters the cooling space.

[0010] Optionally, adjacent partitions are interconnected and enclose each other to form the cooling space, with at least two sub-cooling spaces. Multiple sub-cooling spaces can increase the contact area between the equipment being cooled and the coolant, thereby improving the cooling efficiency of the equipment.

[0011] Optionally, the number of liquid inlet holes in each of the sub-cooling spaces is equal, and the liquid inlet holes are evenly distributed within the area enclosed by the partition. The uniform number and distribution of liquid inlet holes in each sub-cooling space achieves uniform liquid inlet effect.

[0012] Optionally, the number of liquid inlet holes in each of the sub-cooling spaces is greater than or equal to 10. More liquid inlet holes can improve the liquid inlet efficiency, thereby increasing the circulation speed of the coolant in the sub-cooling space, maintaining a larger temperature difference between the coolant and the equipment to be cooled, so as to obtain higher heat exchange efficiency and improve the heat dissipation effect.

[0013] Optionally, the spacing between adjacent liquid inlets within each sub-cooling space is greater than or equal to 2 cm and less than or equal to 5 cm. A spacing greater than 2 cm between liquid inlets ensures that the coolant flow fields between adjacent liquid inlets do not interfere with each other and affect the coolant flow direction, while a spacing less than or equal to 5 cm ensures that the coolant flowing into a single sub-cooling space has a uniform flow direction, avoids turbulence, increases flow velocity, and improves heat dissipation.

[0014] Optionally, the distance between adjacent partitions of adjacent sub-cooling spaces is equal. Equal distance between adjacent partitions of the sub-cooling spaces ensures that the sub-cooling spaces are evenly distributed within the inner liner, allowing the coolant evenly distributed in the inlet space to enter the sub-cooling spaces uniformly, thus improving the stability and uniformity of cooling.

[0015] Optionally, the top of the sub-cooling space is adapted to the top of the inner liner, and the height of the partition is less than or equal to the height of the inner liner. The sub-cooling space and the partition are lower than the height of the inner liner to adapt to the top cover used to seal the inner liner, thereby achieving a seal for the cooling space.

[0016] Optionally, the partition plate has a through hole extending along its thickness and a sealing ring installed on the through hole. The through hole and the sealing ring are engaged and fixed, and the sealing ring is elastic. The sealing ring achieves a sealing effect between the through hole and the cable passing through the through hole into the inner liner, preventing coolant leakage and liquid short circuit.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0026] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0027] In the flow circulation of coolant, the coolant is input from the bottom of the container, and the cooling equipment has cables that need to be connected to the outside of the container and also need to pass through the side wall of the container, which makes the coolant flow complicated. In addition, the existing liquid inlet of the container will affect the flow of coolant and reduce cooling efficiency.

[0028] like Figure 1As shown, this application provides a liquid-cooled cabinet, including a shell 10 and an inner liner 20 disposed inside the shell 10. The inner liner 20 has an opening, and a coolant inlet 21 is formed on the bottom wall of the inner liner 20. The inner liner 20 has a total accommodating space 30. The liquid-cooled cabinet is characterized in that it further includes a baffle 100 and at least one partition 200. The baffle 100 and the partition 200 are both disposed inside the inner liner 20. The baffle 100 is opposite to and spaced apart from the bottom wall of the inner liner 20 to divide the total accommodating space 30 into a liquid inlet space 310 and a cooling space 320. The baffle 100 has a plurality of liquid inlet holes 110 formed on it, which penetrate the baffle 100 along its thickness direction. The liquid inlet holes 110 connect the liquid inlet space 310 and the cooling space 320. The partition 200 is disposed in the cooling space 320 and divides the cooling space 320 into a plurality of sub-cooling spaces 321. The sub-cooling space 321 is filled with coolant. The equipment to be cooled is placed in the coolant and placed on the baffle 100. The coolant enters the inlet space 310 of the inner tank 20 through the coolant inlet 21, and then enters the cooling space 320 through the inlet hole 110 connecting the inlet space 310 and the cooling space 320 to cool the equipment to be cooled. After absorbing heat, it flows out from the top of the cooling space 320. Through the above arrangement, the equipment to be cooled is cooled in multiple sub-cooling spaces 321 respectively, which has the advantages of improving cooling efficiency and cooling uniformity.

[0029] In this embodiment, there are four sub-cooling spaces 321, arranged side by side. Multiple sub-cooling spaces 321 allow for simultaneous heat dissipation from multiple different devices. Compared to placing multiple devices in the same space and having them cooled by the same portion of coolant, the separate cooling of multiple sub-cooling spaces 321 offers the advantage of higher heat dissipation efficiency. The coolant channel corresponding to each sub-cooling space 321 can operate independently of other servers. This allows for more precise cooling control based on the heat load of each device, avoiding the potential problems of low fluid heat transfer efficiency or insufficient localized cooling that can occur with shared coolant. By designing independent cooling paths for each sub-cooling space 321, the flow of coolant can be more precisely controlled, ensuring that the coolant effectively removes heat from high-temperature areas, thereby improving the heat exchange efficiency of the entire cooling system. Multiple sub-cooling spaces 321 can achieve a more uniform airflow distribution in different areas, making the heat dissipation process more uniform and efficient, avoiding the heat concentration problems that may occur in traditional designs, and ensuring that each server receives adequate cooling. Each sub-cooling space 321 serves as an independent cooling unit, allowing for flexible arrangement based on the heat dissipation requirements of different servers. This enhances the flexibility and scalability of the cooling system while avoiding waste of coolant resources. In summary, the design of multiple sub-cooling spaces 321 provides more efficient and independent heat dissipation channels for multiple servers, thereby enhancing the overall performance of the heat dissipation system and making it suitable for environments with high heat dissipation requirements. It should be noted that in other embodiments, the number of sub-cooling spaces 321 can be selected in addition to four, without compromising heat dissipation functionality.

[0030] like Figures 2-4 As shown, the liquid-cooled cabinet also includes a mounting bracket 40, which is supported between the baffle 100 and the bottom wall of the inner liner 20 to form a gap between the baffle 100 and the bottom wall of the inner liner 20. The mounting bracket 40 provides support for the baffle 100, creating a liquid inlet space 310 between the baffle 100 and the bottom wall of the inner liner 20, thereby enabling the coolant to enter each sub-cooling space 321 evenly and improving the uniformity of the cooling effect.

[0031] The mounting bracket 40 includes an integrally connected support portion 41 and a load-bearing portion 42. The load-bearing portion 42 is fitted against the bottom wall surface of the inner liner 20 facing inward. The support portion 41 is fixedly abutted against the baffle 100, and a non-zero angle is formed between the support portion 41 and the bottom wall of the inner liner 20. The fixed fit between the load-bearing portion 42 and the bottom wall of the inner liner 20 increases the contact area and improves the stability of the mounting bracket 40. The support portion 41 supports the baffle 100, and the non-zero angle between the support portion 41 and the bottom wall of the inner liner 20 increases the size of the liquid inlet space 310, allowing for a more uniform distribution of coolant when it enters the cooling space 320.

[0032] like Figure 5 As shown, adjacent partitions 200 are interconnected and surround each other to form the cooling space 320, and the number of sub-cooling spaces 321 is at least two. Multiple sub-cooling spaces 321 can increase the contact area between the equipment to be cooled and the coolant, thereby improving the cooling efficiency of the equipment.

[0033] The number of liquid inlet holes 110 in each of the sub-cooling spaces 321 is equal, and the liquid inlet holes 110 are evenly distributed within the area enclosed by the partition 200. The uniform number and distribution of the liquid inlet holes 110 in each sub-cooling space 321 ensures uniform liquid inlet effect. Uniform coolant flow effectively reduces the operating temperature of the liquid-cooled cabinet, avoids localized overheating, and improves cooling efficiency. The uniform arrangement of the liquid inlet holes 110 optimizes the coolant flow path, thereby improving the performance of the entire cooling system. For the same area, having multiple liquid inlet holes 110, compared to a single liquid inlet hole 110, offers advantages such as uniform fluid distribution, avoids excessively fast or slow flow velocities in localized areas, disperses the liquid flow path to reduce the flow velocity per hole, and thus reduces turbulence and pressure drop during liquid flow.

[0034] The number of liquid inlet holes 110 in each of the sub-cooling spaces 321 is greater than or equal to 10. More liquid inlet holes 110 can improve the liquid inlet efficiency, thereby increasing the circulation speed of the coolant in the sub-cooling space 321, maintaining a larger temperature difference between the coolant and the equipment to be cooled, so as to obtain higher heat exchange efficiency and improve the heat dissipation effect.

[0035] The distance between adjacent liquid inlet holes 110 within each sub-cooling space 321 is greater than or equal to 2 cm and less than or equal to 5 cm. A distance greater than 2 cm between liquid inlet holes 110 ensures that the coolant flow fields between adjacent holes 110 do not interfere with each other, thus preventing interference with the coolant flow direction. A distance less than or equal to 5 cm between liquid inlet holes 110 ensures that the coolant flowing into a single sub-cooling space 321 flows in a uniform direction, avoiding turbulence, increasing flow velocity, and improving heat dissipation.

[0036] The distance between adjacent partitions 200 of adjacent sub-cooling spaces 321 is equal. This equal distance ensures that the sub-cooling spaces 321 are evenly distributed within the inner liner 20, allowing the coolant evenly distributed in the inlet space 310 to enter the sub-cooling spaces 321 uniformly, improving cooling stability and uniformity. Evenly distributed inlet holes 110 guide the coolant flow to various areas, preventing liquid accumulation in certain places, which is crucial for effective heat dissipation. The distribution of inlet holes 110 is identical in each sub-cooling space 321. This consistency ensures that the coolant flow rate in each sub-cooling space 321 is approximately the same, avoiding problems of excessively fast or slow flow rates in some sub-cooling spaces 321, and ensuring balanced coolant flow across different sub-cooling spaces 321. In a cooling system, balanced flow rate is crucial. Different flow rates can lead to uneven heat dissipation efficiency, causing some areas to be over-cooled while others are under-cooled, affecting overall performance. By ensuring a consistent distribution of the inlet holes 110 within each sub-cooling space 321, the efficiency of the cooling system can be maximized. The uniform design of the inlet holes 110 ensures that the coolant flow rate entering the sub-cooling spaces 321 is nearly uniform, reducing temperature differences or uneven cooling effects caused by variations in flow rate. This design helps ensure that the heat dissipation effect within each sub-cooling space 321 is roughly the same. Similar coolant flow rates within each sub-cooling space 321 optimize the heat exchange efficiency of the coolant in different areas, resulting in a balanced heat dissipation capacity across different parts of the cooling system. Because the inlet holes 110 are evenly distributed and have a consistent flow rate, the heat dissipation efficiency within each sub-cooling space 321 remains balanced, preventing situations where some sub-cooling spaces 321 experience excessive cooling while others suffer insufficient cooling. This leads to more stable performance of the entire cooling system and the ability to handle the cooling needs of multiple servers.

[0037] The top of the sub-cooling space 321 is adapted to the top of the inner liner 20, and the height of the partition 200 is less than or equal to the height of the inner liner 20. The sub-cooling space 321 and the partition 200 are lower than the height of the inner liner 20 to adapt to the top cover used to seal the inner liner 20, thereby achieving a seal for the cooling space 320.

[0038] The partition 200 has a through-hole extending along its thickness and a sealing ring installed on the through-hole. The through-hole and the sealing ring are snapped together and fixed. The sealing ring is elastic. The sealing ring achieves a sealing effect between the through-hole and the cable passing through it into the inner liner 20, preventing coolant leakage and liquid short circuits. The sealing ring is fixedly connected to the through-hole, forming a through-hole structure in the middle. The sealing ring can tightly fit the edge of the through-hole, effectively preventing coolant leakage and improving the cabinet's sealing and stability. Furthermore, the material and size of the sealing ring can adapt to different sizes and types of cables, ensuring that aging or damage will not occur during long-term use. In this embodiment, the diameter of the through-hole in the middle of the sealing ring is smaller than the diameter of the cable used. The cable will squeeze the sealing ring, compressing it. The elasticity of the sealing ring achieves a seal between the cable and the through-hole, preventing coolant leakage and liquid short circuits caused by gaps.

Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
