Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a quick-installation air conditioner for advertising machines. Background Technology

[0002] In the field of advertising machines, in order to ensure the stability of core components such as displays, motherboards, and batteries during long-term operation, they need to be equipped with dedicated air conditioners to achieve precise temperature control. In particular, advertising machines are often deployed in crowded places such as shopping malls and subways, where humidity fluctuates greatly. The internal components are dense and the space is enclosed, making them even more reliant on air conditioning systems to maintain a suitable temperature and humidity environment.

[0003] However, existing quick-installation advertising machine air conditioners generally suffer from poor condensation prevention, making it difficult to meet actual usage needs. Currently, the condensation prevention design of existing devices mostly follows the general structure of ordinary air conditioners and has not been optimized for the special usage scenarios of advertising machines. For example, some devices simply set up a water collection tray to collect condensate, but due to the compact internal space of the advertising machine, the size of the water collection tray is limited and the installation position is unreasonable, which easily leads to condensate overflow. The overflowing condensate directly contacts the motherboard, battery and other precision components, which can easily cause short circuits and corrosion of metal contacts. This not only shortens the service life of components, but also causes the advertising machine to suddenly stop, affecting the continuity of advertising. Some existing devices use external drain pipes to drain condensate, but this design conflicts with the "quick installation" requirement of advertising machine air conditioners. During installation, additional holes need to be drilled in the advertising machine casing and support and pipes need to be laid, which increases the installation steps and time costs. This does not meet the installation efficiency requirements for mass deployment of advertising machines, and the drain pipe is prone to clogging due to dust during long-term use, which further aggravates the problem of condensate accumulation.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a quick-installation advertising machine special air conditioner, including a shell 1, an air inlet 4 and an air outlet 22 on the shell 1, an inlet fan 5 and an outlet fan 23 respectively installed in the air inlet 4 and the air outlet 22, a compressor 9 fixedly installed inside the shell 1, a condenser 8 fixedly installed inside the shell 1, and a pipe connecting the output end of the compressor 9 and the input end of the condenser 8. The outer casing 1 provides support for the overall structure. The air inlet 4 and the air outlet 22 are responsible for the intake and exhaust of air, respectively. When the intake fan 5 is running, it introduces external air into the outer casing 1, while the exhaust fan 23 exhausts the hot air in the cooling chamber, forming air circulation. The compressor 9 serves as the cooling power source, compressing the refrigerant and then transporting it to the condenser 8 through pipes. The condenser 8 dissipates heat and cools the high-temperature and high-pressure refrigerant, completing the first step of the refrigeration cycle: heat exchange. A partition is fixedly installed inside the outer casing 1, which divides the interior of the outer casing 1 into a refrigeration chamber and an air duct chamber. The compressor 9 and the condenser 8 are located in the refrigeration chamber. An evaporator 11 is fixedly installed on the partition and is located in the air duct chamber. The input end of the evaporator 11 is connected to the output end of the condenser 8 by a pipe. An expansion valve 10 is fixedly installed on this pipe. The output end of the evaporator 11 is connected to the input end of the compressor 9 by a pipe. The partition divides the interior of the outer shell 1 into an independent refrigeration chamber and an air duct chamber to avoid the mixing of hot and cold air from affecting efficiency. After the compressor 9 and condenser 8 in the refrigeration chamber complete the compression and initial heat dissipation of the refrigerant, the refrigerant flows into the expansion valve 10 through the pipeline. The expansion valve 10 throttles and reduces the pressure of the refrigerant, allowing it to enter the evaporator 11. The evaporator 11 is located in the air duct chamber and exchanges heat with the air introduced by the intake fan 5, absorbing heat from the air to achieve cooling. The refrigerant that has absorbed heat flows back to the compressor 9 through the pipeline, forming a complete refrigeration cycle. A groove 13 is fixedly installed on the outer shell 1, and a support 2 is provided on the top of the outer shell 1. A protrusion 12 is fixedly installed on the support 2. The protrusion 12 is embedded in the groove 13. The outer shell 1 and the support 2 are connected by the cooperation of the protrusion 12 and the groove 13. The outer shell 1 and the support 2 are provided with screw holes. A bolt 6 is threaded in the screw hole, and a washer 7 is fitted on the bolt 6. The groove 13 of the outer shell 1 and the protrusion 12 of the support 2 cooperate to realize the quick positioning of the outer shell 1 and the support 2, which facilitates subsequent fixation. The bolt 6 passes through the screw holes of the outer shell 1 and the support 2 and is tightened. The gasket 7 is used to enhance the connection sealing and firmness, complete the quick installation and fixation of the two, and ensure the stability of the overall structure. A display screen 3 is fixedly installed on the outside of the support 2. A processing box 15 is fixedly installed inside the support 2. A ventilation opening is provided on the side wall of the processing box 15 near the air outlet 21. A motherboard 19 is fixedly installed inside the processing box 15. A battery 20 is fixedly installed inside the processing box 15. Heat dissipation holes 16 are provided at the top and bottom ends of the processing box 15. A cooling fan 18 is fixedly installed at the corresponding heat dissipation holes 16 at the top and bottom ends. The display screen 3 on the outside of the support 2 is an advertising display component. The processing box 15 inside the support 2 provides a protective space for the core electronic control components. The main board 19 is responsible for controlling the overall operation. The battery 20 provides backup power. The ventilation port of the processing box 15 receives the cold air sent in by the air outlet 21 to cool the main board 19 and the battery 20. The heat dissipation hole 16 works with the cooling fan 18 to exhaust the hot air inside the processing box 15, forming an internal air circulation to prevent the components from overheating. Anti-condensation devices are installed on the outer casing 1 and the support 2; The anti-condensation device includes: a hydrophobic layer 14, an air outlet 21, and a waterproof and breathable membrane 17; The air outlet 21 is located on the side of the outer shell 1 near the support 2 and is connected to the air duct where the evaporator 11 is located inside the outer shell 1. The air outlet 21 is connected to the inside of the processing box 15 through the ventilation port of the processing box 15. The hydrophobic layer 14 is fixedly installed on the inner wall of the air outlet 21. The waterproof and breathable membrane 17 is fixedly installed in the heat dissipation holes 16 opened at the upper and lower ends of the processing box 15. In the anti-condensation device, the air outlet 21 sends the cooled air from the evaporator 11 into the processing box 15. The hydrophobic layer 14 on its inner wall reduces the adhesion of condensation when the cold air flows through. The waterproof and breathable membrane 17 in the heat dissipation holes 16 of the processing box 15 allows hot air to be discharged while blocking external moisture from entering, thus preventing condensation from forming in the processing box 15 and protecting components such as the motherboard 19 and battery 20. The display screen 3, condenser 8, compressor 9, expansion valve 10, evaporator 11, main board 19, and battery 20 are existing devices on the market. The following are their model numbers: Display screen 3 uses BOE-AD860U LCD screen, which is a dedicated LCD screen for advertising machines. It has high brightness and wide viewing angle. Its display driving structure can be adapted to the installation requirements of the outside of the support 2, and can stably realize the function of displaying advertising content. It is compatible with the signal output end of the main board 19 to ensure clear and stable display. Condenser 8 uses Midea-CN200 aluminum finned condenser, which is a special condenser for micro air conditioners. It increases the heat dissipation area through fins. Its tube-side structure is compatible with the output pipe of compressor 9, which can efficiently dissipate the heat of high temperature and high pressure refrigerant discharged by compressor 9, and ensure the stability of the heat dissipation link of the refrigeration cycle. Compressor 9 uses HaiLi-TH350 rotary micro compressor, which is a special compressor for small refrigeration equipment. It compresses the refrigerant by rotating the rotor. Its input end is connected to the output end of evaporator 11 and its output end is connected to the input end of condenser 8. It can provide continuous power for the entire refrigeration cycle and meet the refrigeration needs of the device. The expansion valve 10 adopts the Danfoss-TX2 electronic expansion valve, which is a special expansion valve for micro refrigeration systems. It adjusts the refrigerant flow by electronically controlling the valve core opening. Its two ends are connected to the output end of the condenser 8 and the input end of the evaporator 11, respectively. It can accurately control the refrigerant flow into the evaporator 11 and ensure the heat exchange efficiency of the evaporator 11. Evaporator 11 adopts Gree-ZF180 aluminum finned evaporator, which is a special evaporator for micro air conditioners. It enhances the heat exchange contact with the air through fins. It is located in the air duct cavity of the outer shell 1 and exchanges heat with the air introduced by the inlet fan 5. The input end is connected to the expansion valve 10 and the output end is connected to the compressor 9, which can efficiently complete the refrigerant evaporation and heat absorption process. The motherboard 19 uses the Advantech-ARK-2123 industrial-grade advertising machine motherboard, which is a dedicated control motherboard for advertising machines. It integrates signal processing and equipment control chips. It is electrically connected to the display screen 3, battery 20, and cooling fan 18, and can realize advertising content driving, equipment operation status control and fault feedback functions. Battery 20 uses CATL-LFP12V20Ah lithium iron phosphate battery from CATL. This model is a dedicated backup lithium battery for the equipment, featuring long cycle life and safe and stable characteristics. It is installed inside the processing box 15 and electrically connected to the main board 19. It can provide temporary power to the main board 19 and the display screen 3 when the external power is off, ensuring the continuous operation of the core components of the advertising machine for a short period of time.

[0022] Working principle: Compressor 9 compresses the refrigerant and delivers it to condenser 8 for heat dissipation. After being throttled by expansion valve 10, it enters evaporator 11. Inlet fan 5 introduces air to exchange heat with evaporator 11 and cool it down. The cold air is sent into processing box 15 through air outlet 21 to cool mainboard 19 and battery 20. Hot air in processing box 15 is discharged through heat dissipation holes 16 and cooling fan 18. Hot air in the refrigeration chamber is discharged through outlet fan 23 and outlet 22. The refrigerant flows back to compressor 9 to complete the cycle. The outer casing 1 and support 2 are positioned by protrusions 12 and grooves 13 and fixed by bolts 6 to achieve quick assembly and ensure stable operation. In terms of component protection, the hydrophobic layer 14 in the anti-condensation device is fixed to the inner wall of the air outlet 21, which can reduce the adhesion of condensation on the inner wall of the air outlet 21 when cold air flows through. The waterproof and breathable membrane 17 is installed in the heat dissipation hole 16 of the processing box 15, which can block external moisture from entering the processing box 15 while allowing hot air to be discharged, thus preventing condensation or moisture from causing short circuits and corrosion of the motherboard 19 and battery 20, extending the service life of core components, and reducing maintenance difficulty and cost. In terms of ease of installation, the groove 13 of the outer shell 1 and the protrusion 12 of the support 2 can be matched to achieve quick positioning of the two without repeated adjustment of the position. Then, the screw holes on the outer shell 1 and the support 2 are used to fix them with bolts 6 and washers 7. Assembly can be completed without complicated installation tools, which greatly simplifies the installation process and saves installation time and labor costs when advertising machines are deployed in batches.
