Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of refrigeration cabinet technology, and more specifically, to a liquid-cooled cabinet. Background Technology

[0002] Traditional air cooling methods have significant bottlenecks in heat dissipation efficiency. They rely on air as a heat transfer medium, but air has poor thermal conductivity. When the power density of the equipment increases to a certain level, it cannot dissipate heat in time, which can easily lead to excessively high equipment temperature, affecting operational stability and service life. At the same time, air cooling systems often require large-scale fan arrays and complex air duct designs, which not only increases the energy consumption of the equipment but also generates a lot of noise, limiting their applicability in some scenarios with high environmental requirements. Liquid cooling technology has gradually gained attention due to its own advantages. The thermal conductivity and specific heat capacity of liquids are much higher than those of air. When used as a heat transfer medium, liquids can absorb and transfer heat more efficiently, thereby achieving stronger heat dissipation capacity under the same conditions. This can meet the heat dissipation needs of high power density equipment. In addition, liquid cooling systems have relatively low energy consumption, which helps to reduce overall operating costs. They also perform better in terms of noise control and can adapt to more diverse usage environments. Utility Model Content

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-3 As shown, a liquid-cooled cabinet of this disclosure is illustrated, comprising: The electrical control cabinet outer cover 1, and the electrical control cabinet outer cover 1 is equipped with a partition cover 2 inside the electrical control cabinet outer cover 1; Cooling blower assembly 3 is installed inside the outer cover 1 of the electrical control cabinet; The circulating ventilation component 4 is installed on the side wall of the outer cover 1 of the electrical control cabinet; The cooling blower assembly 3 includes a vertical frame 3-1, which is set on the side wall of the outer cover 1 of the electrical control cabinet. A connecting bolt 3-2 is provided on the vertical frame 3-1, and a bolt sleeve 3-3 is provided on the connecting bolt 3-2. The bolt sleeve 3-3 is screwed to the connecting bolt 3-2. A mounting bracket 3-4 is provided on the bolt sleeve 3-3, and a sliding plate 3-5 is provided on the inner side wall of the mounting bracket 3-4. A cooling air outlet pipe 3-6 is provided on the sliding plate 3-5, and a sliding groove 3-7 is opened on the cooling air outlet pipe 3-6. The sliding plate 3-5 is embedded in the interior of the sliding groove 3-7.

[0022] The circulating ventilation component 4 includes a ventilation mesh plate 4-1, which is opened on the outer wall of the electrical control cabinet cover 1. The electrical control cabinet cover 1 is provided with a horizontal frame 4-2. There are several horizontal frames 4-2, and ventilation openings 4-3 are formed between the several horizontal frames 4-2.

[0023] In some examples, the outer casing 1 of the electrical control cabinet can be made of high-quality cold-rolled steel plate. This material has good strength and processing performance, which can meet the structural stability requirements of the cabinet. The partition cover 2 can be made of materials with good fire resistance and heat insulation properties, such as fireproof fiberboard. It can not only effectively isolate different areas inside, but also prevent the spread of fire and heat transfer to a certain extent. The interior of the outer casing 1 of the electrical control cabinet is divided into different functional areas, such as the placement area of ​​the refrigeration blower assembly 3, the equipment installation area, etc., to improve the utilization rate of the internal space of the cabinet and the stability of equipment operation. The mounting holes are pre-set on the side wall of the outer casing 1 of the electrical control cabinet, and the vertical frame 3-1 is fixed to the side wall with connecting bolts 3-2. Installation process In the process, use tools such as a level to ensure that the vertical frame 3-1 is installed vertically to avoid problems in the subsequent installation and use of components due to tilting. The tightening torque of the connecting bolt 3-2 must be operated according to the specified standard to ensure that the frame is installed firmly. Tighten the bolt sleeve 3-3 onto the connecting bolt 3-2, and then install the mounting bracket 3-4 onto the bolt sleeve 3-3. Install sliding pieces 3-5 at opposite ends of the lateral movement of the mounting bracket 3-4. The sliding pieces 3-5 can be fixed to the mounting bracket 3-4 by welding or bolt connection. The installation position of the sliding pieces 3-5 must be precise to ensure that they can be accurately embedded into the sliding groove 3-7 on the cooling air outlet duct 3-6 to achieve flexible sliding of the cooling air outlet duct 3-6.

[0024] Ventilation mesh 4-1 is installed on the outer wall of the electrical control cabinet outer cover 1. The size and mesh density of ventilation mesh 4-1 are determined based on the internal heat dissipation requirements and ventilation flow of the cabinet. Ventilation mesh 4-1 is fixed to the outer cover side wall by screws or clips. During installation, ensure that ventilation mesh 4-1 fits tightly against the outer cover side wall without gaps to prevent dust and other foreign objects from entering the cabinet. Horizontal frames 4-2 are installed inside the electrical control cabinet outer cover 1. The number of horizontal frames 4-2 is determined according to the size of the cabinet and ventilation requirements. During installation, use a level and a vertical gauge to ensure that the horizontal frames 4-2 are installed horizontally and perpendicular to the outer cover side wall. Ventilation openings 4-3 are formed between multiple horizontal frames 4-2. The size and distribution of ventilation openings 4-3 should be uniform to ensure that air can circulate evenly inside the cabinet and improve heat dissipation.

[0025] like Figures 1-3 As shown in the figure, this embodiment proposes that the side wall of the refrigeration air outlet pipe 3-6 is provided with an air outlet valve 3-8, the air outlet valve 3-8 is connected to the refrigeration air outlet pipe 3-6, and the number of air outlet valves 3-8 is several.

[0026] In some examples, an air outlet valve 3-8 is installed on the side wall of the refrigeration air outlet duct 3-6 as needed. The air outlet valve 3-8 is connected to the refrigeration air outlet duct 3-6 by welding or a special connecting pipe fitting. The number of air outlet valves 3-8 is determined according to the actual cooling needs and the requirements for air uniformity. During installation, ensure that the installation position of the air outlet valve 3-8 is accurate, and that the valve opens and closes flexibly to effectively control the air flow and direction.

[0027] For example, such as Figure 1 As shown, the side wall of the outer cover 1 of the electrical control cabinet is provided with an air inlet mesh plate 4-4, which is located on one side of the cooling air outlet pipe 3-6.

[0028] In some examples, the air inlet grille 4-4 can filter the air entering the cabinet, blocking dust, debris, and other contaminants from entering and affecting the normal operation and lifespan of the equipment inside the cabinet. At the same time, the air inlet grille 4-4 is located on the side of the cooling exhaust duct 3-6, which can guide the external air into the cabinet in an orderly manner, forming a reasonable airflow circulation with the cold air discharged from the cooling exhaust duct 3-6, helping to improve the overall heat dissipation efficiency of the cabinet and ensuring that the equipment inside the cabinet works stably in a suitable temperature environment.

[0029] For example, such as Figure 1 As shown, an air inlet pipe 5 is provided on the side wall of the cooling air outlet pipe 3-6. The air inlet pipe 5 is connected to the cooling air outlet pipe 3-6, and one end of the air inlet pipe 5 extends out of the outer cover 1 of the electrical control cabinet.

[0030] In some examples, an air inlet pipe 5 is installed at a suitable position on the side wall of the cooling air outlet pipe 3-6. The air inlet pipe 5 is also connected to the cooling air outlet pipe 3-6 by welding or special connecting pipe fittings. One end of the air inlet pipe 5 extends out of the outer cover 1 of the electrical control cabinet and is used to connect to an external cooling source or air input device. When installing the air inlet pipe 5, it is necessary to ensure that it is well sealed to prevent air leakage and affect the cooling effect. At the same time, the part of the air inlet pipe 5 extending out of the outer cover should be properly protected to avoid damage from external forces.

[0031] For example, such as Figure 3 As shown, a groove 6 is opened on the sliding piece 3-5, and a pulley 7 is provided inside the groove 6. The pulley 7 is embedded inside the groove 3-7.

[0032] In some examples, the cooling air outlet duct 3-6 is mounted on the mounting frame 3-4 via a sliding plate 3-5. The sliding plate 3-5 is embedded inside the sliding groove 3-7 of the cooling air outlet duct 3-6. To further reduce sliding resistance, a groove 6 can be opened on the sliding plate 3-5, and a pulley 7 can be installed inside the groove 6. The pulley 7 is embedded in the sliding groove 3-7. When adjusting the position of the cooling air outlet duct 3-6, the mounting frame 3-4 can be rotated by rotating the bolt sleeve 3-3 on the connecting bolt 3-2, so that the cooling air outlet duct 3-6 can move laterally along the vertical frame 3-1 to meet different cooling and blowing needs.

[0033] For example, such as Figure 3 As shown, a positioning sleeve 8 is provided at the end of the connecting bolt 3-2. The positioning sleeve 8 is connected to the connecting bolt 3-2 through a bearing. The positioning sleeve 8 is in contact with the side wall of the refrigeration air outlet pipe 3-6.

[0034] In some examples, a positioning sleeve 8 is installed at the end of the connecting bolt 3-2. The positioning sleeve 8 is connected to the connecting bolt 3-2 through a bearing. The positioning sleeve 8 contacts the side wall of the cooling air outlet duct 3-6, which serves to support and position the cooling air outlet duct 3-6 and prevent it from shaking or shifting during adjustment.

[0035] For example, such as Figure 3 As shown, the mounting frame 3-4 has a C-shaped structure, and the sliding pieces 3-5 are set at the opposite ends of the lateral movement of the mounting frame 3-4. The two sliding pieces 3-5 are clamped at the two ends of the lateral movement of the cooling air outlet pipe 3-6.

[0036] In some examples, the C-shaped design of the mounting bracket 3-4 allows it to be easily installed on the cooling air outlet duct 3-6.

[0037] During operation, an external cooling source (such as cold air generated by a liquid chiller or cold air after heat exchange with the coolant) enters the cooling outlet duct 3-6 through the inlet duct 5. The inlet duct 5 is connected to the cooling outlet duct 3-6, with one end extending out of the control cabinet cover 1 to reliably receive external cooling. The cooling outlet duct 3-6 releases cooling energy into the cabinet through outlet valves 3-8. Several outlet valves 3-8 are evenly distributed on the side wall of the cooling outlet duct 3-6. The amount of cold air can be controlled by adjusting the valve opening according to the heat dissipation needs of different areas within the cabinet (e.g., in densely populated equipment areas). Increase airflow and decrease airflow in low-heat areas to achieve precise cooling. Rotating the bolt sleeve 3-3 on the connecting bolt 3-2 moves the mounting bracket 3-4 and sliding plate 3-5 along the sliding groove 3-7 of the cooling air outlet duct 3-6 (using pulley 7 to reduce friction), thereby changing the height or angle of the cooling air outlet duct 3-6 to ensure that the cold airflow can cover equipment in different locations within the cabinet. External cold air enters the cabinet through the air inlet grille 4-4 (located on one side of the cooling air outlet duct 3-6, guiding airflow towards the cooling area), and... The cold air released from the cold exhaust duct 3-6 mixes with the cold air to form a low-temperature airflow. This mixed low-temperature airflow flows through the equipment inside the cabinet (such as servers, power supplies, etc.), absorbing the heat generated by the equipment operation and lowering the equipment temperature. The hot air, having absorbed heat, is then exhausted from the cabinet through the circulating ventilation assembly 4. Ventilation openings 4-3 are formed between the horizontal frames 4-2 inside the cabinet, allowing hot air to flow towards the side wall of the cabinet. Finally, the hot air is exhausted to the outside of the cabinet through the ventilation mesh plate 4-1 (located on the side wall of the electrical control cabinet outer cover 1), completing one heat dissipation cycle and cooling the outside of the electrical control cabinet. The interior of cover 1 is divided into different areas to prevent the disorderly mixing of hot and cold airflows inside the cabinet, ensuring that the cold airflow flows preferentially to the high-heat equipment area, thereby improving heat dissipation efficiency. It is connected by bearings and connecting bolts 3-2 and contacts the side wall of the cooling air outlet duct 3-6. It can play a stable supporting role when adjusting the position of the air outlet duct, preventing it from shaking and affecting the stability of the air outlet. The air inlet mesh plate 4-4 and the ventilation mesh plate 4-1 are both mesh structures, which can filter dust, particulate matter and other impurities in the air, preventing impurities from adhering to the equipment surface or entering the refrigeration system, thus avoiding equipment failure or pipe blockage.
