For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] With the development of the times, the demand for facilities such as 5G cabinet air conditioners has also increased year by year. Small and precise 5G cabinet air conditioners have the advantage of being lightweight. At the same time, due to their small size, the locations where their internal components can be installed are also limited, and the layout is dense. Due to the spatial structure limitations inside the 5G cabinet, the installation of the pipeline components of the 5G cabinet is inconvenient, affecting production efficiency.

[0032] To this end, the present application provides a Figures 1 to 5 The cabinet air conditioner shown comprises: a shell 1; a partition 2, the partition 2 is arranged in the shell 1, and the partition 2 divides the shell 1 into an evaporation chamber 11 and a condensation chamber 12; a heat recovery device 3, the heat recovery device 3 is arranged on the partition 2, and the heat recovery device 3 is located in the condensation chamber 12; a first flow channel and a second flow channel are formed in the heat recovery device 3, the first flow channel and the second flow channel can exchange heat with each other, and the first flow channel and the second flow channel are both in the heat exchange cycle of the cabinet air conditioner. Using the first flow channel and the second flow channel in the heat recovery device 3 to replace part of the pipeline in the cabinet air conditioner is equivalent to presetting this part of the pipeline, thereby simplifying the complexity of the pipeline in the cabinet air conditioner, and positioning other parts of the pipeline in the heat exchange cycle of the cabinet air conditioner, facilitating the assembly of the cabinet air conditioner, and heat exchange can be performed between the first flow channel and the second flow channel, and heat transfer in the heat exchange cycle can be achieved at a position other than the evaporator or the condenser, thereby improving the energy efficiency of the cabinet air conditioner.

[0033] As an embodiment, the heat recovery device 3 includes a heat exchange structure 31, and the heat exchange cycle of the cabinet air conditioner includes an air intake pipe 41 and a throttling mechanism. The air intake pipe 41 is inserted into the heat exchange structure 31 to form the first flow channel, and the throttling mechanism is arranged on the heat exchange structure 31 to form the second flow channel. By integrating the air intake pipe 41 and the throttling mechanism on the heat exchange structure 31, it is possible to avoid the problem that the air intake pipe 41 and the throttling mechanism need to be installed separately to affect production efficiency, and the refrigerant in the air intake pipe 41 and the refrigerant in the throttling mechanism can be heat exchanged, thereby reducing the heat dissipated in the system environment and affecting the temperature of the internal environment.

[0034] At the same time, the refrigerant in the suction pipe 41 is used to cool the refrigerant in the throttling mechanism, further reducing the temperature of the refrigerant entering the evaporator, improving the cooling effect of the refrigerant at the evaporator, and also increasing the suction temperature of the compressor, thereby reducing the energy consumption of the compressor and effectively improving the energy efficiency of the cabinet air conditioner.

[0035] Among them, the throttling mechanism includes a capillary tube 42, which is inserted into the heat exchange structure 31, and the capillary tube 42 can exchange heat with the intake pipe 41 through the heat exchange structure 31. As the refrigerant flows in the capillary tube 42, the capillary tube 42 can throttle the refrigerant, and the low-temperature refrigerant in the intake pipe 41 can also absorb the heat of this part of the refrigerant in the throttling state through the heat exchange structure 31 and the capillary tube 42, thereby improving the throttling effect of the refrigerant and improving the refrigeration capacity of the refrigerant.

[0036] Since the refrigerant is in liquid state before throttling, the effect of pre-cooling the refrigerant at this time is poor. Compared with pre-cooling before throttling, the present embodiment can pre-cool during the throttling process, that is, the gaseous refrigerant generated during the throttling process is cooled at the same time, thereby improving the pre-cooling effect of the refrigerant and the heat transfer to the refrigerant, ensuring the heat recovery efficiency of the heat recovery device 3 and the working efficiency of the cabinet air conditioner.

[0037] Specifically, the heat exchange structure 31 includes a plurality of fins, all of which are arranged in parallel, and the intake pipe 41 passes through all of the fins in sequence, and the capillary tube 42 passes through all of the fins in sequence. The fins can ensure heat transfer to the intake pipe 41 and the capillary tube 42, and can also realize integrated fixation of the intake pipe 41 and the capillary tube 42, thereby facilitating the assembly of the cabinet air conditioner.

[0038] The axis of the portion of the intake pipe 41 located in the heat exchange structure 31 is parallel to the axis of the portion of the capillary tube 42 located in the heat exchange structure 31, and the fluid flow direction in the intake pipe 41 is opposite to the fluid flow direction in the capillary tube 42, which can fully realize heat transfer, improve the pre-cooling effect of the refrigerant in the capillary tube 42 and the heating effect of the refrigerant in the intake pipe 41, improve the cooling effect of the refrigerant at the evaporator, and also increase the suction temperature of the compressor, thereby reducing the energy consumption of the compressor and improving the energy efficiency of the cabinet air conditioner.

[0039] The heat recovery device 3 also includes a heat preservation structure, which is wrapped on the heat exchange structure 31. The heat preservation structure is used to prevent the heat in the air intake pipe 41 from being lost into the shell 1 and affecting the temperature in the shell 1, thereby ensuring the working reliability of the cabinet air conditioner.

[0040] The heat recovery device 3 also includes a fluorine injection structure 32, which is connected to the air intake pipe 41, and the fluorine injection structure 32 is located between the heat exchange structure 31 and the compressor. Integrating the fluorine injection structure 32 into the heat recovery device 3 can further reduce the structural complexity of the cabinet air conditioner and facilitate the assembly of the cabinet air conditioner. The fluorine injection structure 32 specifically includes a fluorine injection nozzle and a diverter. The diverter has three connecting ports, two of which are connected in series to the air intake pipe 41, and the third connecting port is connected to the fluorine injection nozzle, and the third connecting port can be opened or closed, which can not only ensure the normal operation of the heat recovery device 3, but also replenish the refrigerant in the heat exchange cycle through the fluorine injection structure 32, further integrate the components of the cabinet air conditioner, reduce the difficulty of assembly, and improve assembly efficiency.

[0041] The heat regenerator 3 further includes a side plate 33, which is disposed at the end of the heat exchange structure 31, and a connection structure is disposed on the side plate 33. When the heat regenerator 3 is installed, the heat regenerator 3 can be fixed to the partition 2 through the connection structure, which is convenient for fixing the heat regenerator 3, and the side plate 33 can also fix the fins to ensure the structural reliability of the heat regenerator 3.

[0042] The heat exchange cycle of the cabinet air conditioner also includes a compressor 43, an evaporator 44 and a condenser 45. The compressor 43 and the condenser 45 are located in the condensation chamber 12, and the evaporator 44 is located in the evaporation chamber 11. The partition 2 is provided with a connecting hole, and the heat recovery device 3 is connected to the evaporator 44 through the connecting hole. When assembling the cabinet air conditioner, the compressor 43, the evaporator 44 and the condenser 45 are respectively arranged at preset positions in the shell 1, and then the air intake of the compressor 43 and the air outlet of the evaporator 44 are respectively connected to the two ends of the first flow channel (the air intake pipe 41), and the liquid outlet of the condenser 45 and the air inlet of the evaporator 44 are respectively connected to the two ends of the second flow channel (the capillary 42), so as to ensure the reliable circulation of the heat exchange cycle.

[0043] The cabinet air conditioner is a 5G cabinet air conditioner. Using the first flow channel and the second flow channel in the heat recovery device to replace part of the pipelines in the cabinet air conditioner is equivalent to presetting this part of the pipeline, thereby simplifying the complexity of the pipelines in the cabinet air conditioner, thereby adapting to the small size and small space of the 5G cabinet air conditioner and facilitating the assembly of the 5G cabinet air conditioner.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
