[0002] Data center cabinets are the infrastructure of data rooms, used to accommodate servers, power supplies and other related electronic equipment. In daily use, a lot of heat is often generated due to load pressure. If the heat cannot be transferred to the outside in time, the temperature of related electronic components will be too high, resulting in reduced work efficiency. In severe cases, the equipment will be overheated and damaged, causing great losses. Existing cabinet cooling devices on the market generally adopt air cooling, that is, the generated heat is dissipated through the form of heat dissipation ducts. At the same time, vents need to be set on the cabinet itself, which is easy to accumulate dust, reduce heat dissipation efficiency, and affect the service life of the equipment. In addition, air cooling has problems such as high noise and low heat dissipation efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is that using air cooling alone to dissipate heat in the cabinet will cause relatively large noise and easily deposit dust.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a composite air-cooled and liquid-cooled heat dissipation intelligent cabinet, comprising a cabinet body, a ventilation structure arranged at the bottom of the cabinet body, a water cooling component installed on the ventilation structure and an air outlet channel arranged on both side walls of the cabinet body, the water cooling component comprising a liquid delivery component, a heat exchange pipe connected to a condensate tank in the liquid delivery component and a fan arranged above the heat exchange pipe.

[0005] Preferably, a partition is fixedly provided inside the cabinet, the fan is installed on the partition, the ventilation structure includes an air inlet arranged at the bottom of the cabinet, partitions are arranged on both sides of the air inlet, and a sealing plate is connected between the movable ends of the two partitions, and the heat exchange tube is located at the top of the air inlet.

[0006] Preferably, one end of the partition abuts against the inner end surface of the cabinet, and blocks for buckling the support plate are correspondingly provided between the partition and the opposite side walls of the cabinet. The blocks are located at the ends of the partition and are equidistantly distributed along the height direction of the partition.

[0007] Preferably, the top and bottom of one end of the partition facing the outside of the cabinet are fixedly connected with locking blocks, the locking blocks are connected to the cabinet by bolts, and the inner edge of the cabinet is equidistantly provided with threaded holes corresponding to the through holes on the locking blocks in the width direction.

[0008] Preferably, the heat exchange tube is arranged in an S shape, one end of the heat exchange tube is connected to the output end of the condensate delivery pump in the liquid delivery assembly, and the other end is connected to the condensate tank, and a connecting block is fixedly connected to the top of the air inlet duct, and the side wall of the connecting block is provided with a limiting groove for clamping the end of the heat exchange tube.

[0009] Preferably, the air outlet channel is an opening provided at the top of the cabinet side wall, a dust screen is installed in the opening, and a side baffle is fixedly and obliquely installed at the top of the cabinet side wall, and the side baffle is located directly above the dust screen.

[0010] Preferably, a temperature sensor signal-connected to the fan and the liquid delivery component is installed on the top of the cabinet, and the temperature sensor is located on one side of the dustproof net.

[0012] Preferably, the four corners of the bottom of the cabinet are vertically fixedly connected with pillars.

[0013] A method for using an air-cooled and liquid-cooled composite heat dissipation intelligent cabinet comprises the following steps: S1, temperature detection, using a temperature sensor to detect the temperature between the partitions in the cabinet, and transmit the detected temperature information to the control unit of the water cooling component; S2, the control unit compares the detected temperature value with the set temperature value. When the detected temperature value exceeds the set temperature value by 20%, the condensate is transported in the heat exchange tube and the fan starts to rotate; S3, the temperature sensor continues to detect the temperature inside the cabinet, and the control unit continues to compare the received temperature value. If the temperature does not drop, the flow rate of the condensate in the heat exchange tube and the speed of the fan are increased, and when the received temperature value is lower than the set temperature value, the condensate delivery in the heat exchange tube and the fan are stopped.

[0014] 1. The present invention provides an air-cooled and liquid-cooled composite heat dissipation intelligent cabinet, which combines liquid cooling and air cooling to improve the heat dissipation efficiency of the cabinet body, so that the equipment in the cabinet can operate in a low and stable temperature environment for a long time, reducing performance degradation and component damage caused by overheating, thereby significantly extending the service life of the equipment.

[0015] 2. The hybrid cooling system can respond to temperature changes more quickly, ensuring that the temperature inside the cabinet can be effectively controlled even under high load or extreme working conditions. This helps maintain the stable operation of the equipment and improves the reliability and stability of the overall system.

[0016] 3. Cooperate with temperature sensors for intelligent adjustment, increase or decrease the fan speed of the air cooling device and the power of the electric pump, achieve intelligent adjustment and autonomous control, and ensure the intelligent controllability of the entire system.

[0022] A ventilation structure is installed at the bottom of the cabinet 1, and the air is discharged through the bottom and then through the air outlet channels on both sides. A water cooling component is installed on the ventilation structure, and the condensate in the heat exchange tube 5 is transported through the external liquid delivery component 12. During the transportation process, the air passes through the heat exchange tube 5, and the condensate exchanges heat with the air through the heat exchange tube 5, so that the air entering the cabinet 1 is cooled and then transported through the fan 7, so as to cool the inside of the cabinet 1 and ensure the safe and stable operation of the electronic equipment inside the cabinet 1.

[0023] like Figure 1The cabinet 1 is fixedly provided with a partition 6, the fan 7 is mounted on the partition 6, the ventilation structure comprises an air inlet 3 arranged at the bottom of the cabinet 1, partitions 6 are arranged on both sides of the air inlet 3, and a sealing plate is connected between the movable ends of the two partitions 6, and the heat exchange tube 5 is located at the top of the air inlet 3.

[0024] The space inside the cabinet 1 is divided by setting two partitions 6 and a sealing plate, so that the air inlet 3 is independent of the interior of the cabinet 1. A filter is installed inside the air inlet 3 to reduce dust in the air entering the cabinet 1; and the top of the air inlet 3 extends upward, which can improve the waterproofness of the bottom of the cabinet 1.

[0025] like Figure 1 One end of the partition 6 abuts against the inner end surface of the cabinet 1, and a clamping block 9 for buckling the support plate is correspondingly arranged between the partition 6 and the opposite side wall of the cabinet 1. The clamping block 9 is located at the end of the partition 6 and is equidistantly distributed along the height direction of the partition 6.

[0026] By mounting the support board on the card block 9, the card blocks 9 at both ends stably support the support board, and the electronic equipment is installed through the support board. Providing multiple layers of card blocks 9 can install multiple layers of support boards to ensure the capacity of electronic equipment.

[0027] like Figure 1 The top and bottom of the partition plate 6 facing the outer side of the cabinet 1 are fixedly connected with a locking block 8, the locking block 8 is connected to the cabinet 1 by bolts, and the inner edge of the cabinet 1 is equidistantly provided with threaded holes corresponding to the through holes on the locking block 8 in the width direction.

[0028] According to the number and volume of electronic equipment to be installed in the cabinet 1, adjust the position of the partition 6 inside the cabinet 1, and use the locking block 8 and bolts to vertically fix the partition 6. Use the block 9 at the end of the partition 6 to abut the end against the inner wall of the cabinet 1 to ensure that the partition 6 is arranged perpendicular to the cabinet 1.

[0029] As a preferred embodiment of the present invention. The heat exchange tube 5 is arranged in an S shape, one end of the heat exchange tube 5 is connected to the output end of the condensate delivery pump in the liquid delivery component 12, and the other end is connected to the condensate tank. The top of the air inlet 3 is fixedly connected with a connecting block 4, and the side wall of the connecting block 4 is provided with a limiting groove for clamping the end of the heat exchange tube 5. The condensate enters through one end of the heat exchange tube 5, and exchanges heat with the incoming air during the process of flowing through the heat exchange tube 5. The heat exchange efficiency is ensured by increasing the heat exchange area; the stability of the installation of the heat exchange tube 5 is ensured by the limiting groove on the connecting block 4.

[0030] like Figure 1 and Figure 2The air outlet channel is an opening opened at the top of the side wall of the cabinet 1, and a dust screen 10 is installed in the opening. A side baffle 11 is fixedly installed at an angle on the top of the side wall of the cabinet 1, and the side baffle 11 is located directly above the dust screen 10. The arrangement of the dust screen 10 is used to reduce the entry of external dust into the cabinet 1, and the side baffle 11 is used to waterproof the cabinet 1.

[0031] As a preferred embodiment of the present invention, a temperature sensor connected to the fan 7 and the liquid delivery component 12 is installed on the top of the cabinet 1 , and the temperature sensor is located on one side of the dustproof net 10 .

[0032] The temperature of the outlet air is detected by the temperature sensor, and the temperature inside the cabinet 1 can be deduced from the outlet air temperature. When the controller receives a temperature signal transmitted by the temperature sensor that exceeds the set value, the controller starts the fan 7 and the liquid delivery component 12 to cool down the inside of the cabinet 1. If the temperature sensor always keeps delivering a high temperature signal, the controller controls the alarm to sound and flash. The fan 7 is disposed at the bottom and the top of the partition 6 . The fan 7 at the bottom is disposed toward the heat exchange tube 5 , and the fan 7 at the top is disposed toward the dustproof net 10 .

[0033] like Figure 1 and Figure 2 As shown, the four corners of the bottom of the cabinet 1 are vertically fixedly connected with pillars 2. The cabinet 1 is raised by the pillars 2, which can prevent the bottom of the cabinet 1 from being corroded by ground water.

[0034] A method for using an air-cooled and liquid-cooled composite heat dissipation intelligent cabinet comprises the following steps: S1, temperature detection, using a temperature sensor to detect the temperature between the partitions in the cabinet 1, and transmitting the detected temperature information to the control unit of the water cooling component; S2, the control unit compares the detected temperature value with the set temperature value. When the detected temperature value exceeds the set temperature value by 20%, the condensate is transported in the heat exchange tube 5 and the fan 7 starts to rotate; S3, the temperature sensor continues to detect the internal temperature of the cabinet 1, and the control unit continues to compare the received temperature value. If the temperature does not drop, the flow rate of the condensate in the heat exchange tube 5 and the speed of the fan 7 are increased, and after the received temperature value is lower than the set temperature value, the condensate delivery in the heat exchange tube 5 and the fan 7 are stopped.
