Further, as shown in fig. 6, the evaporating fan assembly 30 includes an evaporating fan mounting plate 31 and a plurality of first centrifugal fans 32 mounted on the evaporating fan mounting plate 31, and the evaporating fan mounting plate 31 is provided with evaporating side avoiding holes 311 corresponding to air inlets of the first centrifugal fans 32. Wherein the air outlet of the first centrifugal fan 32 is directed toward the evaporation air supply port 114.
The evaporation fan mounting plate 31 is further provided with a fan bracket 33 for limiting the first centrifugal fan 32, and the fan bracket 33 is provided with an evaporation side air passing hole 331 along the second direction.
In a specific embodiment, the number of first centrifugal fans 32 is two, and the evaporation fan assembly 30 further includes an evaporation side baffle 34 disposed between the two first centrifugal fans 32; an evaporation side connector 35 is connected between the fan brackets 33 corresponding to each of the two first centrifugal fans 32.
In other alternative embodiments, the first centrifugal fan 32 is one in number and is mounted to the evaporation fan mounting plate 31 by a fan bracket 33.
Further, as shown in fig. 2 and 3, a condensation side chamber 13 is also formed in the cabinet 10. The condensation-side cavity 13 is disposed above the evaporation-side cavity 11 in the present embodiment, and the internal structure of the condensation-side cavity 13 and the components therein in fig. 2 are omitted for the convenience of the skilled person.
In the condensation side cavity 13, the cabinet 10 is sequentially installed with the heat-releasing and heat-exchanging device 50 and the condensation fan assembly 60 from bottom to top (i.e., a third direction), wherein the third direction is perpendicular to the first direction and the second direction, respectively. The heat-releasing and heat-exchanging device 50 can be a water-cooled condenser, an air-cooled condenser or the like, which uses an outdoor cold source to cool the refrigerant.
A condensation air inlet 131 is arranged at a position of the condensation side cavity 13 opposite to the air inlet side of the heat release and exchange device 50, and a condensation air outlet 132 is arranged at a position of the condensation side cavity 13 opposite to the air outlet side of the condensation fan assembly 60. That is, on the condensation side cavity 13, the cabinet 10 is provided with a condensation air inlet 131 and a condensation air outlet 132 opened along the first direction. In this embodiment, outdoor air enters the cabinet 10 from the condensation air inlet 131 at the lower part, passes through the heat release and heat exchange device 50 and the condensation fan assembly 60 in sequence, and is discharged out of the cabinet 10 from the condensation air outlet 132 at the upper part after heat exchange is completed.
It should be understood that, the outdoor air circulation of the cabinet air conditioner of the embodiment is arranged along the first direction, and the indoor air circulation circulates along the second direction, so that the cabinets can be connected in succession along the second direction, no matter how many cabinets are connected, the overall circulation effect of the outdoor air circulation cannot be affected, namely, the refrigerating effect is stable, namely, the cabinet air conditioner of the embodiment has the advantage of high stability.
In addition to the above embodiments, the cabinet 10 includes a frame 14. The frame 14 is formed by splicing three rectangular frames and is distributed in a concave shape.
The evaporation side air flow opening 111 (including the evaporation return air inlet 113 and the evaporation air supply outlet 114) and the electric control overhaul opening 112 are formed on the frame body 14, and a condensation side overhaul opening 133 formed on the frame body 14 along the first direction is formed on the same side as the electric control overhaul opening 112, and the condensation side overhaul opening 133 is located on the same side. Wherein, the evaporation side airflow opening 111 is formed on the rectangular frames on both sides along the second direction, and the rectangular frames are also formed with condensation side airflow openings 134; the function of the evaporation side air flow opening 111 is as described above, and the indoor cold air passing through the heat absorption and refrigeration heat exchange device 20 flows out of the cabinet 10 through the evaporation side air flow opening 111, and returns to the cabinet 10 through the evaporation side air flow opening 111 after the target refrigeration is completed; as described above, the condensation-side access opening 133 allows a worker to easily maintain the inside evaporation fan assembly 30 and the electronic control device 40 after opening the cabinet door 153 described below; when the condensation side airflow opening 134 is used for connecting a plurality of cabinet air conditioners, the heat release and exchange devices 50 inside the cabinet air conditioners are communicated with each other, and the uniformity of refrigeration is improved.
The frame 14 is further rotatably connected with a cabinet door 153 for blocking the electric control overhaul opening 112 and the condensation side overhaul opening 133, and the cabinet door 153 is provided with a condensation air inlet 131 and a condensation air outlet 132 corresponding to the condensation side overhaul opening 133. Additionally, the frame 14 is further provided with a rear plate 154, and the rear plate 154 is disposed opposite to the cabinet door 153 and disposed on the other side of the frame 14. More specifically, locks such as bluetooth locks, fingerprint locks, mechanical locks and the like for locking connection with the frame 14 are mounted on the cabinet door 153, and locking structures such as bolts are provided between the first side plate 151 and the second side plate 152 and the frame 14.

The housing 14 is also rotatably connected to a second side plate 152 for closing the condenser side air flow opening 134. For example, when one side of the cabinet air conditioner needs to be connected to a target (such as an equipment cabinet, a communication cabinet, etc.), after the cabinet door 153 is opened, the locking between the corresponding first side plate 151 and the frame 14 is released from the inner side of the cabinet body 10, and after the first side plate 151 on one side is opened, the evaporation side airflow opening 111 can be communicated with the corresponding target; for example, when the heat-releasing heat exchanger 50 needs to be subjected to fire maintenance, the cabinet door 153 may be opened, the corresponding locking between the second side plate 152 and the frame 14 may be released from the inside of the cabinet 10, and the second side plate 152 on one side may be opened, so that the components may be subjected to fire maintenance from outside to inside.
Further, as shown in fig. 7, the condensing fan assembly 60 includes two guide rails 61 mounted to the cabinet 10 and extending in a direction away from the first side. I.e. the condensation fan assembly 60 comprises two guide rails 61 mounted on the cabinet 10 and extending in a first direction.
The guide rail 61 is slidably connected with a condensing fan mounting plate 62, and a second centrifugal fan 63 is mounted on the condensing fan mounting plate 62; the distance between the two guide rails 61 decreases along the direction away from the first side, which may also be understood as that the distance between the two guide rails 61 decreases along the extending direction of the condensing fan mounting plate 62, that is, the guide rails 61 adopt a wedge structure.
After the condensing fan mounting plate 62 extends into the condensing side cavity 13, the condensing fan mounting plate 62 is connected with the guide rail 61 through a connecting piece.
