Description

Technical Field

[0001] The present application relates to the field of liquid cooling and heat dissipation, and in particular to a liquid cooling cabinet system. Background Art

[0002] In today's era of rapid technological development, liquid cooling cabinets, as an advanced heat dissipation solution, are gradually gaining widespread attention.

[0003] Liquid cooling cabinet is a cabinet system that uses liquid circulation to remove heat from equipment. It usually consists of a cabinet, liquid cooling module, circulation pump, coolant, etc. Compared with traditional air cooling, liquid cooling cabinet has many significant advantages.

[0004] First of all, efficient heat dissipation is the outstanding advantage of liquid cooling cabinets. The specific heat capacity of liquid is much greater than that of air, and it can absorb more heat. This allows liquid cooling cabinets to more effectively reduce the temperature of equipment and ensure that the equipment maintains stable performance under high load operation. For those servers, data centers and other equipment with high power density and high heat generation, liquid cooling cabinets can provide reliable heat dissipation protection to avoid equipment failure and performance degradation caused by overheating.

[0005] Secondly, liquid cooling cabinets have the characteristic of low noise. Traditional air cooling often relies on high-speed rotating fans for air circulation, which will produce a lot of noise. Liquid cooling cabinets mainly dissipate heat through the silent flow of liquid, which greatly reduces the operating noise and creates a quieter and more comfortable working environment for staff.

[0006] Furthermore, liquid cooling cabinets can achieve compact designs. Due to the high heat dissipation efficiency of liquid, efficient heat dissipation can be achieved in a smaller space. This allows the liquid cooling cabinet to be designed more compactly, saving room space and improving space utilization. This is a very important advantage for data centers with limited space.

[0007] In addition, liquid cooling cabinets also have the advantages of energy saving and environmental protection. On the one hand, efficient heat dissipation can reduce the energy consumption of equipment and reduce energy waste. On the other hand, due to the high heat dissipation efficiency of liquid cooling cabinets, it can reduce the dependence on auxiliary heat dissipation equipment such as air conditioners, thereby further reducing energy consumption. At the same time, some coolants can also be recycled, reducing the impact on the environment.

[0008] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: conventional liquid-cooled cabinets are generally equipped with water cooling towers to cool the coolant. This method directly draws the high-temperature coolant in the cabinet into the water cooling tower for spraying and cooling, resulting in low heat dissipation efficiency. Summary of the invention

[0009] In order to improve the problem of low heat dissipation efficiency, the present application provides a liquid cooling cabinet system.

[0010] A liquid cooling cabinet system provided in the present application adopts the following technical solution: a liquid cooling cabinet system, including a cabinet body and a water cooling system, the cabinet body having a cooling cavity, characterized in that: the cabinet body is provided with multiple heat exchange cavities, each heat exchange cavity corresponds to a side wall of the cabinet body; the water cooling system includes a water cooling tower, a first circulation pump, a cooling water inlet pipe and a cooling water outflow pipe, the cooling water inlet pipe and the cooling water outflow pipe are both connected to the heat exchange cavity, and each heat exchange cavity is connected to a cooling water inlet pipe and a cooling water outflow pipe.

[0011] By adopting the above technical solution, one heat dissipation path is that the coolant enters the heat exchange chamber and exchanges heat with the cooling water flowing into the water cooling tower, and another heat dissipation path is that the coolant directly exchanges heat with the cooling water in the heat exchange chamber through the outer wall of the cooling chamber. The cooling rate of the coolant is increased by the dual-path heat dissipation method, thereby ultimately improving the heat dissipation effect of the heat dissipation device in the cooling chamber.

[0012] Optionally, the cooling liquid cavity is connected to a cooling liquid circulation system, which includes a second circulation pump, a cooling liquid inlet pipe and a cooling liquid outlet pipe, and the cooling liquid outlet pipe passes through the heat exchange cavity.

[0013] Optionally, the cooling liquid chamber is connected to a cooling liquid circulation system, which includes a second circulation pump, a cooling liquid inlet pipe and a cooling liquid outlet pipe; a partition is arranged in the middle of the heat exchange chamber to divide the heat exchange chamber into a first chamber and a second chamber, the first chamber is connected to a cooling water inlet pipe and a cooling water outlet pipe, the second chamber is connected to the cooling liquid inlet pipe and the cooling liquid outlet pipe, and the first chamber is located between the second chamber and the cooling chamber.

[0014] By adopting the above technical solution, the heat exchange chamber is divided into a first chamber and a second chamber for cooling water and coolant respectively, and the first chamber for cooling water is arranged between the second chamber and the cooling chamber to achieve two-path heat dissipation.

[0015] Optionally, the separator is wavy in shape.

[0016] By adopting the above technical solution, the wave-shaped partition has a larger contact surface, a larger heat exchange area, and a higher heat exchange efficiency.

[0017] Optionally, the volume of the first chamber is 2.5-3 times the volume of the second chamber.

[0018] By adopting the above technical solution, since the first chamber performs double-sided heat exchange, the volume of the first chamber needs to be enlarged to ensure that sufficient cooling water can achieve heat dissipation through two paths.

[0019] Optionally, the separator is a flexible heat-conductive film, and the area of ​​the flexible heat-conductive film is larger than the area of ​​the heat exchange cavity.

[0020] By adopting the above technical solution, the flexible heat-conducting film will be deformed to produce a larger contact surface.

[0021] Optionally, the flexible thermally conductive film includes a thermally conductive silicone rubber film and a metal wire located on the thermally conductive silicone rubber film.

[0022] By adopting the above technical solution, the design of the metal wire facilitates the heat transfer effect of the heat-conducting film to be better. On the other hand, the metal wire itself has a shaping effect, which can be used to change the size of the first chamber and the second chamber or adjust the heat transfer surface area. The metal wire is preferably copper wire / fiber. When making it, the copper wire is generally woven into a copper mesh first, and then the copper mesh is placed in a mold and injected with molten liquid silicone, and then cooled and shaped.

[0023] A liquid cooling cabinet system comprises a cabinet body and a dry cooler, wherein the cabinet body has a cooling cavity, and is characterized in that: the cabinet body is provided with a plurality of heat exchange cavities, each heat exchange cavity corresponds to a side wall of the cabinet body; the dry cooler comprises a fan and a dry cooling pipeline, the dry cooling pipeline is located in the heat exchange cavity, the fan faces the dry cooling pipeline, and the heat exchange cavity has an air inlet and an air outlet; the cooling liquid cavity is connected to a cooling liquid circulation system, the cooling liquid circulation system comprises a third circulation pump, a cooling liquid inlet pipe and a cooling liquid outlet pipe, the cooling liquid inlet pipe and the cooling liquid outlet pipe are connected to the dry cooling pipeline, and the dry cooling pipeline is located between the cooling liquid inlet pipe and the cooling liquid outlet pipe.

[0024] The coolant in the cooling chamber enters the dry cooling pipeline and is cooled by the fan before flowing back to the cooling chamber. This method has no external cold source and a simpler structure. When the fan blows through the heat exchange chamber, it also dissipates heat on the outer wall of the cooling chamber, thereby improving the heat dissipation effect through dual-path heat dissipation.

[0025] Optionally, the fan is located outside the air inlet and spaced apart from the air inlet.

[0026] By adopting the above technical solution, external air will not only enter from the back of the fan, but also from the gap between the fan and the air inlet, so that the air flows faster and the heat dissipation efficiency is higher.

[0027] Optionally, the liquid cooling cabinet system further includes a water cooling tower, and the wind from the fan passes through the water cooling tower and then blows toward the dry cooling pipeline.

[0028] By adopting the above technical solution, the wind passing through the water cooling tower is colder, and the cooling effect of the coolant in the dry cooling pipeline is better.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. By opening a heat exchange cavity on the side wall of the cabinet, the coolant is cooled by water cooling or dry cooling. The setting of the heat exchange cavity allows two heat dissipation paths to be provided at the same time, resulting in a better heat dissipation effect. 2. The air temperature is lowered by setting up an additional water cooling tower in the dry cooling tower, thereby making the heat exchange efficiency of the dry cooling pipeline higher.
