Description

Technical Field

[0001] The present invention relates to the technical field of cabinet heat exchangers, and in particular to a heat exchange device for an integrated cabinet. Background Art

[0002] A cabinet is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. It typically features doors, removable or non-removable side panels, and a back panel. It is an integral component of electrical equipment and serves as a carrier for electrical control devices. It is typically made of cold-rolled steel or alloys and can provide protection against water, dust, and electromagnetic interference. Traditional integrated cabinets are usually equipped with air conditioners for heat dissipation. However, due to the long-term continuous high-load operation of the air conditioners, the air conditioners in the integrated cabinets are generally short-lived and difficult to repair. In addition, the inconsistent specifications and sizes of different manufacturers lead to poor air tightness of the cabinet after replacement. Existing cabinet cooling air conditioners are usually installed on the inner wall of the cabinet, which requires drilling holes in the inner wall and damages the overall structure of the cabinet side wall. Moreover, when the mains power outside the cabinet is interrupted, the communication equipment inside the cabinet generates continuous heat that cannot be dissipated, causing the local temperature to rise too quickly, causing the network management system to trigger a high-temperature alarm, affecting the operation quality of the network equipment, and requiring maintenance personnel to go to the station and open the door for physical heat dissipation.

[0023] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0024] according to Figures 1-8 As shown, this embodiment proposes a heat exchange device for an integrated cabinet, comprising a heat exchange body and a mounting bracket 1. The heat exchange body is mounted on one side of the outer wall of the integrated cabinet through the mounting bracket 1. The heat exchange body includes an installation cabinet 2, an air intake assembly, an air supply assembly, a return air assembly, an exhaust assembly, a heat dissipation mechanism and a battery pack 3. An air intake assembly is provided on one side of the lower end of the installation cabinet 2, and an air supply assembly connected to the integrated cabinet is provided on the other side. An exhaust assembly is provided on the same side of the upper end of the installation cabinet 2 as the air intake assembly, and a return air assembly connected to the integrated cabinet is provided on the same side of the upper end of the installation cabinet 2 as the air supply assembly. A heat dissipation mechanism is connected between the air intake assembly and the air supply assembly. A support plate 4 is provided on the top of the heat dissipation mechanism, and a battery pack 3 is fixed on the support plate 4.

[0025] The hot air inside the cabinet is then drawn out by the return air assembly and exhausted to the outside through the exhaust assembly.

[0026] The air inlet assembly includes a first turbine fan unit 5, an installation bin 6 and a removable bin cover 7. The input end of the first turbine fan unit 5 passes through the side wall of the installation cabinet 2 and extends to the outside. The output end of the first turbine fan unit 5 is connected to the installation bin 6. A removable bin cover 7 is installed on one side of the installation bin 6. A moisture-absorbing sponge 8 with honeycomb holes is provided inside the installation bin 6.

[0027] This device draws outside air into the installation chamber 6 by setting a first turbine fan unit 5, and at the same time, a moisture-absorbing sponge 8 is set in the installation chamber 6 to dry the air, thereby ensuring the dryness of the air entering in rainy weather. At the same time, a removable chamber cover 7 is set on one side of the installation chamber 6. By removing the chamber cover by disassembling the card, the installation chamber 6 can be opened to replace the moisture-absorbing sponge 8.

[0028] The air supply assembly, return air assembly and exhaust assembly have the same structure and all include a second turbo fan unit 9. One end of the second turbo fan unit 9 passes through the side wall of the installation cabinet 2 and extends to the outside. The first turbo fan unit 5 and the second turbo fan unit 9 are both electrically connected to the battery pack 3.

[0029] By providing multiple sets of second turbine fan units 9, continuous air intake and exhaust are ensured, thereby increasing the fluidity of the air and further enhancing the heat exchange effect of the device.

[0030] A partition 10 is provided above the battery pack 3 , and both ends of the partition 10 are fixedly connected to the inner wall of the mounting cabinet 2 . The partition 10 forms a conveying channel between the return air component and the exhaust air component.

[0031] Through the separate conveying channel formed between the partition 10 and the installation cabinet 2, the suction force of the two sets of second turbine fan units 9 is coordinated to ensure the rapid discharge of hot air and prevent the hot air from diffusing inside the installation cabinet 2.

[0032] The heat dissipation mechanism includes a heat dissipation air conditioner 11, a connecting hose 12, a three-way solenoid valve 13 and a cold supply pipe 14. A connecting hose 12 is provided between the detachable compartment cover 7 and the second turbine fan unit 9 in the air supply assembly. A heat dissipation air conditioner 11 is provided above the connecting hose 12. A three-way solenoid valve 13 is provided on the connecting hose 12. The three-way solenoid valve 13 is connected to the input end of the heat dissipation air conditioner 11. The output end of the heat dissipation air conditioner 11 is connected to the input end of the second turbine fan unit 9 in the air supply assembly through the cold supply pipe 14. A check valve is provided on the cold supply pipe 14. The three-way solenoid valve 13 is electrically connected to the battery pack 3.

[0033] When the utility power is normally supplied, the air sucked in by the first turbine fan unit 5 is sent to the heat dissipation air conditioner 11 through the connecting hose 12 for cooling through the three-way solenoid valve 13. The cooled air is sent to the second turbine fan unit 9 in the air supply assembly through the cooling pipe 14. The second turbine fan unit 9 sends the cold air into the integrated cabinet, thereby cooling the interior of the integrated cabinet. The hot air is sucked out through the second turbine fan unit 9 in the return air assembly and discharged through the second turbine fan unit 9 in the exhaust assembly. When the utility power is cut off, the heat dissipation air conditioner 11 cannot work, and the battery pack 3 Temporary power is supplied to the three-way solenoid valve 13, the first turbine fan unit 5 and the second turbine fan unit 9, and the first turbine fan unit 5 is directly connected to the second turbine fan unit 9 in the air supply assembly through the three-way solenoid valve 13, so that the inhaled outside air is directly sent into the integrated cabinet, thereby dissipating the heat inside and preventing the integrated cabinet from shutting down due to excessive temperature caused by the non-operation of the heat dissipation air conditioner 11. In winter, when the outdoor temperature is not high, it can also be cooled directly by outside air, so that the heat dissipation air conditioner 11 does not need to work, thereby reducing energy waste.

[0034] A matching drying tube 15 is provided in the moisture-absorbing sponge 8 , and both ends of the drying tube 15 are connected to the hot end of the heat dissipation air conditioner 11 .

[0035] This device fully takes into account the influence of high temperature and rainy season in summer. By setting a drying tube 15 inside the moisture-absorbing sponge 8, the hot air sent out from the hot end of the heat dissipation air conditioner 11 is sent into the drying tube 15, and the moisture-absorbing sponge 8 is dried through the drying tube 15 to ensure that the moisture-absorbing sponge 8 continues to absorb moisture.

[0036] Multiple groups of heat sinks 16 are arranged in the conveying channel, and the multiple groups of heat sinks 16 are staggered. One end of the multiple groups of heat sinks 16 passes through the rear wall of the installation cabinet 2 and extends to the outside. The outer ends of the multiple groups of heat sinks 16 are fixed with protective plates 17.

[0037] This device dissipates heat from the air entering the installation cabinet 2 by arranging heat sinks 16 in the conveying channel, thereby reducing the internal operating temperature of the installation cabinet 2. At the same time, the staggered structure ensures the flow spacing of the hot air and the density of the heat sinks 16, greatly increasing the heat dissipation effect.

[0038] The mounting bracket 1 includes a fixing seat 18, a rotating bolt 19, a pressure plate 20, a block 21, a support arm 22 and a clamping plate 23. The fixing seat 18 is installed at the center of the top of the mounting cabinet 2. The rotating bolt 19 is threadedly installed at the center of the top of the fixing seat 18. A first cavity 24 is provided inside the fixing seat 18. The pressure plate 20 is slidably installed in the first cavity 24. The lower end of the rotating bolt 19 is rotatably connected to the pressure plate 20. The bottom of the pressure plate 20 is annular. There are four groups of card blocks 21 distributed in the array. A first cavity 25 is provided on the fixing seat 18 below the first cavity 24. The end of the support arm 22 is inserted into the first cavity 25. The first cavity 25 is provided with a slot 29 adapted to the card block 21. The pressure plate 20 slides down to drive the card block 21 to be clamped into the slot 29 to fix the support arm 22 to the fixing seat 18. A splint 23 is provided on the support arm 22. Two groups of the splints 23 connect the heat exchange body to the integrated cabinet by clamping.

[0039] The support arm 22 is provided with a sliding groove, which is adapted to the splint 23. A threaded rod 26 is rotatably installed in the sliding groove. The end of the support arm 22 is provided with a rotating handle 27 for driving the threaded rod 26 to rotate. One end of the splint 23 is inserted into the sliding groove and is threadedly connected to the threaded rod 26. A rubber pad 28 is provided on the inner side of the splint 23.

[0040] When installing the device, the ends of the two groups of support arms 22 are inserted into the second empty slots, and then the rotating bolts 19 are rotated to drive the pressing plate 20 downward, thereby pushing the inserting plate to be inserted into the notch 29 on the support arm 22, thereby fixing the support arm 22. Then, the threaded rod 26 is rotated by rotating the rotating handle 27, thereby driving the clamping plate 23 to move, so that the two groups of clamping plates 23 clamp the integrated cabinet, thereby connecting and fixing the device to the integrated cabinet without the need for drilling installation.

[0041] The heat exchange device for the integrated cabinet uses a three-way solenoid valve 13 to allow the air sucked in by the first turbo fan unit 5 to be sent into the heat dissipation air conditioner 11 through the connecting hose 12 for cooling. The cooled air is sent to the second turbo fan unit 9 in the air supply assembly through the cooling pipe 14. The second turbo fan unit 9 of this group sends the cold air into the integrated cabinet, thereby cooling the interior of the integrated cabinet, while the hot air is sucked out through the second turbo fan unit 9 in the return air assembly and discharged through the second turbo fan unit 9 in the exhaust assembly. When the mains power is off, the heat dissipation air conditioner 11 cannot work, and the battery pack 3 temporarily supplies power to the three-way solenoid valve 13, the first turbo fan unit 5 and the second turbo fan unit 9, and directly connects the first turbo fan unit 5 with the second turbo fan unit 9 in the air supply assembly through the three-way solenoid valve 13, so that the inhaled outside air is directly sent into the integrated cabinet, thereby dissipating the heat inside.
