[0028] The utility model is further described in conjunction with the following embodiments.

[0029] Depend on Figures 1 to 5 It can be seen that the integrated air conditioner described in this embodiment includes a body 1; the body 1 is provided with an indoor chamber 2 and an outdoor chamber; the indoor chamber 2 is provided with a first heat exchanger 4; the first heat exchanger 4 divides the indoor chamber 2 into a return air chamber 21 and a supply air chamber 22; the return air chamber 21 is provided with a return air port 31; the supply air chamber 22 is provided with an air supply fan 32;

[0030] The outdoor chamber is provided with a second heat exchanger 53, a fresh air outlet 54 and an outdoor fan 55;

[0031] An inclined partition is provided between the indoor cavity 2 and the outdoor cavity.

[0032] Specifically, the integrated air conditioner described in this embodiment integrates all key components such as the air supply fan 32, the outdoor fan 55, the compressor, the evaporator, the condenser and the electric control box into the body 1, and when in use, Figure 1 As shown, the machine body 1 is integrated as a whole at the end of the container 9, thereby saving indoor space; in addition, all key components such as the air supply fan 32, the outdoor fan 55, the compressor, the evaporator, the condenser and the electric control box are integrated in the machine body 1, which is convenient for full outdoor maintenance.

[0033] Secondly, this embodiment sets an inclined partition to separate the return air channel of the indoor cavity 2 from the fresh air channel of the outdoor cavity. The inclined partition can not only make the airflow at the inlet and outlet of the return air channel of the indoor cavity 2 turn more smoothly and reduce the resistance of the air duct structure, but also help the outdoor fan 55 of the outdoor cavity to guide the airflow to exchange heat with the second heat exchanger 53.

[0034] In the integrated air conditioner described in this embodiment, the outdoor cavity includes a first outdoor cavity 51 disposed on the side close to the return air cavity 21 and a second outdoor cavity 52 disposed on the side close to the supply air cavity 22; the first outdoor cavity 51 and the second outdoor cavity 52 are both provided with a second heat exchanger 53, a fresh air outlet 54 and an outdoor fan 55;

[0035] The inclined partition includes a first inclined partition 61 disposed between the first outdoor cavity 51 and the return air cavity 21 , and a second inclined partition 62 disposed between the second outdoor cavity 52 and the supply air cavity 22 .

[0036] Specifically, through the above-mentioned configuration, when the container 9 is refrigerated, the first heat exchanger 4 is used as an evaporator and the second heat exchanger 53 is used as a condenser; this embodiment provides two second heat exchangers 53, two fresh air inlets 54 and two groups of outdoor fans 55, thereby realizing dual-system operation in the machine body 1, and the dual systems can share the evaporator, thereby improving the refrigeration efficiency.

[0037] In the integrated air conditioner described in this embodiment, a middle plate 11 and a back plate 12 are provided in the body 1; the middle plate 11, the back plate 12, the first inclined partition plate 61 and the second inclined partition plate 62 form the indoor cavity 2; the return air port 31 and the air supply fan 32 are respectively provided on the back plate 12. Specifically, the structure of the indoor cavity 2 is stable and reliable through the above arrangement.

[0038] In the integrated air conditioner described in this embodiment, the length of the back plate 12 is greater than the length of the middle plate 11; the back plate 12 is arranged in parallel with the middle plate 11; the back plate 12, the middle plate 11, the first inclined partition 61 and the second inclined partition 62 form a trapezoidal structure. In the integrated air conditioner described in this embodiment, the end of the first inclined partition 61 away from the first heat exchanger 4 is arranged close to the fresh air outlet 54 of the first outdoor chamber 51; the end of the second inclined partition 62 away from the first heat exchanger 4 is arranged close to the fresh air outlet 54 of the second outdoor chamber 52.

[0039] Specifically, through the above-mentioned arrangement, when the container 9 is normally cooled, under the action of the air supply fan 32, the gas in the hot channel of the container 9 enters the return air chamber 21 from the return air port 31, and under the guiding action of the first inclined partition 61, the gas enters the air supply chamber 22 after heat exchange of the evaporator, and then under the guiding action of the second inclined partition 62, the gas is sent into the cold channel of the container 9 through the air supply fan 32.

[0040] In addition, under the action of the outdoor fan 55, the external fresh air enters the outdoor cavity from the fresh air inlet 54, and under the guidance of the first inclined baffle 61 and the second inclined baffle 62, the fresh air is discharged to the outside after heat exchange in the condenser.

[0041] In this embodiment, a first inclined partition 61 and a second inclined partition 62 are provided to separate the return air channel of the indoor cavity 2 from the fresh air channel of the outdoor cavity. The first inclined partition 61 and the second inclined partition 62 can cooperate with the trapezoidal air duct structure to make the airflow at the inlet and outlet of the return air channel of the indoor cavity 2 turn smoothly and reduce the resistance of the air duct structure, and it is also beneficial for the outdoor fan 55 in the outdoor cavity to guide the airflow to exchange heat with the condenser.

[0042] In the integrated air conditioner described in this embodiment, the first heat exchanger 4 is tilted and arranged between the back plate 12 and the middle plate 11; the tilt direction of the first heat exchanger 4 is the same as the tilt direction of the first tilt partition 61. Specifically, the tilt direction of the first heat exchanger 4 is the same as the tilt direction of the first tilt partition 61, so that the expansion valve and the liquid distributor can be arranged close to one end of the first heat exchanger 4, so that the refrigerant can be fully liquefied in the pipeline from the condenser to the expansion valve, the refrigerant supercooling degree is improved, and more liquid enters the evaporator. At the same time, the liquid distributor is close to the evaporator, and the pipeline resistance is small if the pipeline is short, which reduces the evaporation amount of the liquid refrigerant in the liquid distributor after passing through the expansion valve, so that the refrigerant can fully evaporate and cool in the evaporator, avoiding the loss of cooling capacity. At the same time, it is convenient to inspect the expansion valve from the indoor return air inlet during later maintenance, and the space is large enough for easy operation.

[0043] In the integrated air conditioner described in this embodiment, the inclined partition is provided with heat-insulating cotton. The above arrangement can block the heat transfer between the indoor cavity 2 and the outdoor cavity.

[0044] In the integrated air conditioner described in this embodiment, the first inclined partition 61 is movably provided with an exhaust door 71; the second inclined partition 62 is movably provided with a fresh air door 81; a first electric push rod 72 and a second electric push rod 82 are provided in the indoor cavity 2; the output end of the first electric push rod 72 is connected to the exhaust door 71; the output end of the second electric push rod 82 is connected to the fresh air door 81.

[0045] Specifically, when the air conditioner is out of power or the compressor fails and cannot provide cooling, the temperature inside the container 9 will rise sharply and eventually become higher than the outdoor temperature.

[0046] At this time, the first electric push rod 72 and the second electric push rod 82 contract, so that the fresh air door 81 and the exhaust door 71 open and block the air duct and the evaporator, the outdoor fan 55 stops working and the supply air fan 32 continues to run, and the outdoor air passes through the fresh air door 81 and the supply air fan 32 in turn to continue to provide cooling for the cold channel of the container 9, thereby urgently cooling the server cabinet, and the high-temperature air in the hot channel of the container 9 is discharged to the outside through the return air port 31 and the exhaust door 71.

[0047] In the integrated air conditioner described in this embodiment, a fresh air filter is provided at the opening of the second inclined partition plate 62 corresponding to the fresh air door 81. The above arrangement prevents dust in the outdoor air from entering the container 9.

[0048] In the integrated air conditioner described in this embodiment, the fresh air door 81 and the exhaust door 71 are both provided with heat insulation cotton. The above arrangement can block the heat transfer between the indoor cavity 2 and the outdoor cavity, and at the same time play a sealing role when the fresh air door 81 and the exhaust door 71 are not opened.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
