[0035] In the description of the present invention, "first feature" and "second feature" may include one or more such features.

[0036] In the description of the present invention, “multiple” means two or more, and “several” means one or more.

[0037] Please refer to the following Figures 1-10 A computer room air conditioner 100 according to an embodiment of the present invention is described.

[0038] like Figures 1-7 As shown, a computer room air conditioner 100 according to an embodiment of the present invention includes a casing 10 , a heat exchanger 20 and a fan 30 .

[0039] The housing 10 can be placed outdoors or indoors and has an air inlet 11 and an air outlet 12. The heat exchanger 20 is disposed in the housing 10 and is adjacent to the air inlet 11. The fan 30 is disposed in the housing 10 and is adjacent to the air outlet 12.

[0040] Specifically, the fan 30 drives outdoor air into the casing 10 from the air inlet 11, and the outdoor air exchanges heat with the heat exchanger 20 to form a heat exchange airflow, which is driven by the fan 30 to flow out of the casing 10 from the air outlet 12 and into the room.

[0041] In this way, the computer room air conditioner 100 can selectively control outdoor air to enter the casing 10 through the air inlet 11, and the outdoor air can form a heat exchange airflow after heat exchange with the heat exchanger 20, and then flow out of the casing 10 from the air outlet 12 driven by the fan 30, thereby cooling the room.

[0042] The refrigerant flows in the heat exchanger 20 so that the outdoor air entering the casing 10 exchanges heat with the refrigerant in the heat exchanger 20. This can reduce the temperature of the outdoor air entering the casing 10, so that the temperature of the heat exchange airflow is lower than the indoor ambient temperature. In this way, when the heat exchange airflow enters the room, it can cool the room.

[0043] The heat exchanger 20 is disposed in the casing 10 , so that the casing 10 can protect the heat exchanger 20 and ensure the reliability and working stability of the heat exchanger 20 in the computer room air conditioner 100 .

[0044] Furthermore, the heat exchanger 20 is arranged adjacent to the air inlet 11 , so that the outdoor air can flow directly to the heat exchanger 20 after entering the casing 10 , thereby improving the efficiency of forming the heat exchange airflow and being beneficial to improving the cooling effect of the computer room air conditioner 100 .

[0045] The two sides opposite to each other in the first direction of the casing 10 are set to be a first side panel 17 and a second side panel 18, the air inlet 11 is formed on the first side panel 17, and the air outlet 12 is formed on the second side panel 18. In this way, the air inlet 11 and the air outlet 12 can be arranged opposite to each other on both sides of the first direction of the casing 10.

[0046] The first side panel 17 or the second side panel 18 is respectively adapted to be fitted with the inner and outer sides of the wall 200 so that the air inlet 11 or the air outlet 12 is adapted to be connected to the ventilation opening 2001 on the wall 200, thereby enabling the computer room air conditioner 100 to be located on the inner side or the outer side of the wall 200.

[0047] According to some embodiments of the present application, the first side plate 17 of the casing 10 is attached to the wall 200, and to ensure that outdoor air can smoothly enter the indoor, the casing 10 needs to be installed in the indoor of the machine room, so that the air outlet 12 on the second side plate 18 of the casing 10 is located in the indoor, so that the heat exchange airflow in the casing 10 can flow into the indoor through the air outlet 12.

[0048] Further, the air inlet 11 on the first side plate 17 of the casing 10 is communicated with the ventilation opening 2001 on the wall 200, so that the outdoor air can flow through the ventilation opening 2001 of the wall 200 and the air inlet 11 of the casing 10 in sequence, and then enter the casing 10, so that the machine room air conditioner 100 can be installed in the indoor.

[0049] According to some embodiments of the present application, the second side plate 18 of the casing 10 is attached to the wall 200, and to ensure that outdoor air can smoothly enter the indoor, the casing 10 needs to be installed in the outdoor of the machine room, so that the air inlet 11 on the second side plate 18 of the casing 10 is located in the outdoor, so that the outdoor air can flow into the casing 10 through the air inlet 11.

[0050] Further, the air outlet 12 on the second side plate 18 of the casing 10 is communicated with the ventilation opening 2001 on the wall 200, so that the outdoor air entering the casing can form a heat exchange airflow, and then flow into the indoor of the machine room through the air outlet 12 on the casing 10 and the ventilation opening 2001 on the wall 200 in sequence, so that the machine room air conditioner 100 can be installed in the outdoor.

[0051] In this way, the machine room air conditioner 100 in the embodiments of the present application can meet the requirements of indoor and outdoor installation by forming the air inlet 11 and the air outlet 12 on the opposite sides of the casing 10 in the first direction.

[0052] According to the embodiments of the present application, the windward surface of the heat exchanger 20 is parallel to the first side plate 17 and / or the second side plate 18 of the casing 10, the heat exchanger 20 and the fan 30 are arranged in the second direction, and the air inlet 11 and the air outlet 12 are arranged in the second direction.

[0053] Specifically, the heat exchanger 20 is arranged in the second direction at a position adjacent to the air inlet 11 in the casing 10, so that the area of the windward surface of the heat exchanger 20 is maximized, which is beneficial to improve the heat exchange efficiency and improve the refrigeration efficiency of the machine room air conditioner 100.

[0054] In some embodiments of the present invention, the heat exchanger 20 is parallel to the first side panel 17 of the casing 10, and the side of the heat exchanger 20 adjacent to the air inlet 11 is the windward side of the heat exchanger 20. When the second side panel 18 is installed in close contact with the wall 200, the maximum windward side of the heat exchanger 20 can be guaranteed, which is beneficial to increase the contact area between the windward side of the heat exchanger 20 and the outdoor air, thereby helping to improve the heat exchange efficiency between the air and the refrigerant.

[0055] In other embodiments of the present invention, the heat exchanger 20 is parallel to the second side panel 18 of the casing 10, and the side of the heat exchanger 20 adjacent to the air inlet 11 is the windward surface of the heat exchanger 20. When the second side panel 18 is installed in close contact with the wall 200, the maximum windward surface of the heat exchanger 20 can be guaranteed, which is beneficial to increase the contact area between the windward surface of the heat exchanger 20 and the outdoor air, thereby helping to improve the heat exchange efficiency between the air and the refrigerant.

[0056] In some further embodiments of the present invention, the first side panel 17 and the second side panel 18 are opposite sides of the housing 10 in a first direction, and the heat exchanger 20 is parallel to the first side panel 17 and the second side panel 18 of the housing 10. When the computer room air conditioner 100 is installed indoors, the first side panel 17 of the housing 10 is installed flush with the wall 200, thereby ensuring that the heat exchanger 20 remains parallel to the wall 200. When the computer room air conditioner 100 is installed outdoors, the second side panel 18 of the housing 10 is installed flush with the wall 200, thereby ensuring that the heat exchanger 20 remains parallel to the wall 200. With this arrangement, whether the computer room air conditioner 100 is installed indoors or outdoors, the heat exchanger 20 remains parallel to the wall 200. This ensures that the windward surface of the heat exchanger 20 has a larger contact area with the outdoor air, thereby ensuring higher heat exchange efficiency of the heat exchanger 20 and, in turn, better cooling performance of the computer room air conditioner 100.

[0057] The heat exchanger 20 and the fan 30 are spaced apart in the second direction. In this way, the heat exchanger 20 and the fan 30 can be arranged simultaneously in the casing 10 without increasing the size of the computer room air conditioner 100 in the first direction. The heat exchanger 20 can be arranged adjacent to the air inlet 11, and the fan 30 can be arranged adjacent to the air outlet 12. In this way, the heat exchange airflow in the computer room air conditioner 100 can be ensured to flow from the air inlet 11 to the air outlet 12.

[0058] The air inlet 11 and the air outlet 12 are spaced apart in the second direction. This not only ensures that the heat exchanger 20 is arranged adjacent to the air inlet 11 and the fan 30 is arranged adjacent to the air outlet 12, but also helps to form a stable heat exchange airflow in the casing 10 to improve the air outlet uniformity of the computer room air conditioner 100.

[0059] In an embodiment of the present invention, the first direction and the second direction are perpendicular to each other.

[0060] Combine Figure 6 、 Figure 9 and Figure 10 As shown, the computer room air conditioner 100 also includes an electronic control component 40, which is arranged in the casing 10. The casing 10 can protect the electronic control component 40 and prevent outdoor dust and rainwater from contaminating the electronic control component 40. In this way, the safety of the electronic control component 40 can be guaranteed.

[0061] Furthermore, the heat exchanger 20 and the fan 30 are both connected to the electronic control component 40 by signal, so that the flow of refrigerant in the heat exchanger 20 can be controlled, and the operating state and rotation rate of the fan 30 can be controlled to control the temperature and flow rate of the heat exchange airflow formed in the computer room air conditioner 100, thereby adjusting the temperature and wind speed of the cold air blown into the room, and further adjusting the cooling efficiency of the computer room air conditioner 100 in the computer room.

[0062] In an embodiment of the present invention, the computer room air conditioner 100 can adjust its operating state according to the outdoor temperature.

[0063] When the outdoor temperature is higher than the indoor temperature of the computer room and lower than the first preset value, the electronic control component 40 controls the heat exchanger 20 and the fan 30 to work simultaneously. At this time, after the outdoor air enters the casing 10 through the air inlet 11, it can exchange heat with the heat exchanger 20 to reduce the temperature of the outdoor air, and then driven by the fan 30, enter the room through the air outlet 12.

[0064] When the outdoor temperature is lower than the room's indoor temperature, the electronic control unit 40 activates the fan 30 and deactivates the heat exchanger 20. At this point, outdoor air enters the housing 10 through the air inlet 11 and flows through the heat exchanger 20 without exchanging heat with the heat exchanger. Driven by the fan 30, the heat exchanged air flows directly into the room through the air outlet 12. This allows the room's interior to be cooled directly by the low-temperature outdoor air, while the heat exchanger 20 is deactivated, thereby reducing the energy consumption of the room air conditioner 100.

[0065] The electronic control component 40 is spaced apart from one side of the heat exchanger 20 away from the air inlet 11 along the first direction, and the electronic control component 40 and the fan 30 are spaced apart from each other in the second direction.

[0066] With such an arrangement, on the one hand, the electronic control component 40 can be arranged adjacent to the heat exchanger 20 and the fan 30 in the housing 10 , so as to facilitate the connection between the electronic control component 40 and the heat exchanger 20 and the fan 30 .

[0067] On the other hand, not only can the heat exchanger 20 be arranged near the air inlet 11 so that the outdoor air flows directly to the heat exchanger 20 after entering the casing 10, thereby improving the efficiency of forming the heat exchange airflow, but the electronic control component 40 can also be arranged near the air outlet 12, which can ensure that the heat exchange airflow flows out of the casing smoothly, which is beneficial to improving the cooling effect of the computer room air conditioner 100 on the indoor environment of the computer room.

[0068] Combine Figure 1 、 Figure 2 、 Figure 6 and Figure 8 As shown, an electric control inspection port 13 is provided on at least one side of the housing 10 in the third direction, and the electric control component 40 can be selectively drawn out from the electric control inspection port 13 along the third direction.

[0069] Specifically, the electric control maintenance port 13 can be used to repair the electric control component 40 in the casing 10 by only opening the electric control maintenance port 13 when a fault occurs in the electric control component 40. The electric control component 40 is set to be selectively pulled out from the electric control maintenance port 13 along a third direction. In this way, when the electric control maintenance port 13 is opened, the electric control component 40 can be quickly found, and the electric control component 40 can be directly repaired and replaced, which is convenient to operate.

[0070] In this manner, the embodiment of the present invention provides an electrical control inspection port 13 on at least one side of the casing 10 in the third direction, and the electrical control component 40 and the electrical control inspection port 13 correspond to each other in the third direction. This allows the computer room air conditioner 100 to meet indoor and outdoor installation requirements while facilitating inspection and maintenance of the electrical control component 40.

[0071] In an embodiment of the present invention, the first direction, the second direction and the third direction are perpendicular to each other.

[0072] According to an embodiment of the present invention, the computer room air conditioner 100 further includes a filter 50. The filter 50 is disposed within the housing 10. Air can pass through the filter 50 smoothly, while dust and impurities in the air cannot pass through the filter 50. This allows the air in the computer room air conditioner 100 to be filtered, thereby improving the cleanliness of the air in the computer room air conditioner 100 and preventing the computer room air conditioner 100 from blowing outdoor dust into the room, thereby preventing pollution in the computer room.

[0073] Combine Figure 1 、 Figure 4 、 Figure 7 and Figure 8As shown in Figs. 1-3, the filter screen 50 is located between the air inlet 11 and the heat exchanger 20, so that the outdoor air flowing into the casing 10 through the air inlet 11 first flows to the filter screen 50 before flowing to the heat exchanger 20. The dust content in the outdoor air flowing to the heat exchanger 20 is greatly reduced under the filtration of the filter screen 50, so that the cleanliness of the heat exchange airflow in the machine room air conditioner 100 can be improved, and the possibility of dust entering the indoor room can be effectively reduced.

[0074] If the filter screen replacement opening 14 is arranged on the first side plate 17 or the second side plate 18 of the casing 10, when the first side plate 17 or the second side plate 18 of the casing 10 is installed in abutment with the wall 200, the filter screen replacement opening 14 can be blocked by the wall 200, which can result in that the filter screen 50 cannot be taken out, and the filter screen 50 can be taken out only by disassembling the machine room air conditioner 100, which is inconvenient and time-consuming and laborious.

[0075] In the embodiment of the present application, the casing 10 is provided with the filter screen replacement opening 14 on at least one side in the third direction, and the filter screen 50 can be selectively pulled out from the filter screen replacement opening 14 in the third direction.

[0076] In this way, the filter screen 50 can be easily and conveniently taken out and cleaned after the filter screen replacement opening 14 is opened, so that the filter screen 50 can be easily cleaned when the machine room air conditioner 100 in the present application is installed indoors and outdoors, and the structural layout of the machine room air conditioner 100 can be made more reasonable.

[0077] In combination with Figs. 1-3, Figure 1 , Figure 4 , Figure 7 and Figure 8 , the filter screen replacement opening 14 and the electric control maintenance opening 13 are located on the same side of the casing 10 in the third direction, and the filter screen replacement opening 14 and the electric control maintenance opening 13 are arranged in the first direction.

[0078] Specifically, in the embodiment of the present application, the filter screen replacement opening 14 and the electric control maintenance opening 13 are both located on the casing 10 and on the same side of the casing 10 in the third direction, so that the installation of the filter screen replacement opening 14 and the electric control maintenance opening 13 can be facilitated, and when the filter screen 50 is replaced or the electric control assembly 40 is maintained, only the operation on the same side of the casing 10 in the third direction is needed, without the need to change the operation position, so that the maintenance convenience of the machine room air conditioner 100 can be improved, and the maintenance efficiency of the machine room air conditioner 100 can be improved.

[0079] Further, the filter screen replacement opening 14 and the electric control maintenance opening 13 are arranged in the first direction, so that the filter screen replacement opening 14 and the electric control maintenance opening 13 can be arranged independently on the same side of the third direction of the casing 10, and the opening and closing processes of the filter screen replacement opening 14 and the electric control maintenance opening 13 can be avoided from interfering with each other.

[0080] On the other hand, the electric control assembly 40 corresponding to the electric control maintenance opening 13 in the third direction and the filter screen 50 corresponding to the filter screen replacement opening 14 in the third direction can be arranged independently in the casing 10, so as to ensure the working reliability of the electric control assembly 40 and the filter screen 50 in the casing 10.

[0081] In combination with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 , at least one side of the third direction of the casing 10 is provided with the refrigerant inlet and outlet pipe interface 15, which is adapted to be connected with the refrigerant inlet and outlet pipe.

[0082] Specifically, the refrigerant inlet and outlet pipe interface 15 includes a refrigerant inlet pipe interface and a refrigerant outlet pipe interface. The refrigerant inlet pipe interface corresponds to the refrigerant inlet pipe of the heat exchanger 20, so that the low-temperature refrigerant can flow into the heat exchanger 20 through the refrigerant inlet pipe. The refrigerant outlet pipe interface corresponds to the refrigerant outlet pipe of the heat exchanger 20, so that the refrigerant exchanged with the outdoor air in the heat exchanger 20 can flow out of the heat exchanger 20 through the refrigerant outlet pipe. In this way, the refrigerant in the heat exchanger 20 can be circulated, and the refrigeration function of the machine room air conditioner 100 can be ensured.

[0083] In combination with Figure 1 , Figure 3 and Figure 4 , the refrigerant inlet and outlet pipe interface 15, the filter screen replacement opening 14 and the electric control maintenance opening 13 are located on the same side of the third direction of the casing 10, so that the refrigerant inlet and outlet pipe interface 15, the filter screen replacement opening 14 and the electric control maintenance opening 13 can be arranged away from the first side plate 17 and the second side plate 18 of the casing 10. In this way, the first side plate 17 and the second side plate 18 of the machine room air conditioner 100 can be attached to the wall 200, so as to facilitate the installation of the machine room air conditioner 100 in the indoor and outdoor.

[0084] Further, the refrigerant inlet and outlet pipe interface 15 is arranged in the first direction between the filter replacement opening 14 and the electric control maintenance opening 13, so that the refrigerant inlet and outlet pipe interface 15 is arranged separately from the filter replacement opening 14 and the electric control maintenance opening 13 on the same side of the third direction of the casing 10, so as to ensure the structural reliability of the refrigerant inlet and outlet pipe interface 15 on the casing 10, and ensure the connection reliability of the refrigerant inlet and outlet pipe interface 15 and the refrigerant inlet and outlet pipe, so as to ensure the reliability of the circulation of the refrigerant in the heat exchanger 20.

[0085] In combination with Figure 7 , Figure 9 and Figure 10 , the machine room air conditioner 100 further comprises a water pan 60, which can be used to collect the condensed water in the machine room air conditioner 100 and discharge through the drain opening 16, so as to prevent the condensed water from gathering in the machine room indoor to cause damage to the hardware facilities in the supermarket or damage to the hardware facilities in the machine room.

[0086] Further, in the embodiment of the utility model, the water pan 60 is arranged in the casing 10, and it is located on the side of the heat exchanger 20 away from the fan 30 along the second direction, so as to receive the condensed water condensed and fallen on the heat exchanger 20, and then collect the condensed water on the heat exchanger 20 and discharge the machine room air conditioner 100.

[0087] Further, the casing 10 is provided with a drain opening 16 on at least one side of the third direction, and the drain opening 16 is in communication with the water pan 60, so that the condensed water in the water pan 60 can be discharged through the drain opening 16, and the condensed water in the water pan 60 can be prevented from overflowing due to excessive accumulation.

[0088] In combination with Figure 1 , Figure 3 and Figure 4 , the drain opening 16, the refrigerant inlet and outlet pipe interface 15, the filter replacement opening 14 and the electric control maintenance opening 13 are all located on the same side of the third direction of the casing 10, the drain opening 16 and the refrigerant inlet and outlet pipe interface 15 are arranged in the first direction between the filter replacement opening 14 and the electric control maintenance opening 13, and the refrigerant inlet and outlet pipe interface 15 is arranged in the second direction away from the drain opening 16.

[0089] Specifically, in order to facilitate the installation and maintenance operation of the machine room air conditioner 100, the drain opening 16, the refrigerant inlet and outlet pipe interface 15, the filter replacement opening 14 and the electric control maintenance opening 13 on the casing 10 of the machine room air conditioner 100 are all arranged on the same side of the third direction of the casing 10.

[0090] Further, the drain port 16 and the refrigerant inlet and outlet pipe interface 15 are arranged between the filter screen replacement port 14 and the electric control maintenance port 13, so that the drain port 16 and the refrigerant inlet and outlet pipe interface 15 can be arranged away from the filter screen replacement port 14 and the electric control maintenance port 13, and the filter screen 50 in the machine shell 10 can be correspondingly arranged in the third direction with the filter screen replacement port 14, and the electric control assembly 40 in the machine shell 10 can be correspondingly arranged in the third direction with the electric control maintenance port 13.

[0091] In this way, the structural layout of the machine room air conditioner 100 can be optimized, the structural arrangement of the machine room air conditioner 100 suitable for indoor and outdoor installation in the utility model can be more reasonable, and thus the installation, use and maintenance of the machine room air conditioner 100 can be facilitated.

[0092] As shown in Figures 1-7 The machine room air conditioner 100 according to the embodiment of the utility model comprises a machine shell 10, a heat exchanger 20 and a fan 30.

[0093] The machine shell 10 can be arranged in an outdoor or indoor environment, and an air inlet 11 and an air outlet 12 are formed on the machine shell 10. The heat exchanger 20 is arranged in the machine shell 10 and adjacent to the air inlet 11. The fan 30 is arranged in the machine shell 10 and adjacent to the air outlet 12.

[0094] Specifically, the fan 30 drives outdoor air to enter the machine shell 10 from the air inlet 11, and the outdoor air is heated with the heat exchanger 20 to form a heat exchange air flow, and then the heat exchange air flow is driven by the fan 30 to flow out of the machine shell 10 from the air outlet 12 and enter the indoor environment.

[0095] In this way, the machine room air conditioner 100 can selectively control the outdoor air to enter the machine shell 10 through the air inlet 11, and the outdoor air can be heated with the heat exchanger 20 to form a heat exchange air flow, and then the heat exchange air flow is driven by the fan 30 to flow out of the machine shell 10 from the air outlet 12, thereby cooling the indoor environment.

[0096] The refrigerant flows in the heat exchanger 20 to heat the outdoor air entering the machine shell 10 with the refrigerant in the heat exchanger 20, so that the temperature of the outdoor air entering the machine shell 10 can be reduced, and the temperature of the heat exchange air flow can be lower than the temperature of the indoor environment, so that the heat exchange air flow can cool the indoor environment when entering the indoor environment.

[0097] The heat exchanger 20 is arranged in the machine shell 10, so that the machine shell 10 can protect the heat exchanger 20, and the reliability of the arrangement of the heat exchanger 20 in the machine room air conditioner 100 and the working stability can be ensured.

[0098] Furthermore, the heat exchanger 20 is arranged adjacent to the air inlet 11 , so that the outdoor air can flow directly to the heat exchanger 20 after entering the casing 10 , thereby improving the efficiency of forming the heat exchange airflow and being beneficial to improving the cooling effect of the computer room air conditioner 100 .

[0099] The two sides opposite to each other in the first direction of the casing 10 are set to be a first side panel 17 and a second side panel 18, the air inlet 11 is formed on the first side panel 17, and the air outlet 12 is formed on the second side panel 18. In this way, the air inlet 11 and the air outlet 12 can be arranged opposite to each other on both sides of the first direction of the casing 10.

[0100] The first side panel 17 or the second side panel 18 is respectively adapted to be fitted with the inner and outer sides of the wall 200 so that the air inlet 11 or the air outlet 12 is adapted to be connected to the ventilation opening 2001 on the wall 200, thereby enabling the computer room air conditioner 100 to be located on the inner side or the outer side of the wall 200.

[0101] According to some embodiments of the present invention, the first side panel 17 of the casing 10 is installed in close contact with the wall 200. In order to ensure that outdoor air can enter the room smoothly, the casing 10 needs to be installed indoors in the machine room. This ensures that the air outlet 12 on the second side panel 18 of the casing 10 is located indoors, so that the heat exchange airflow in the casing 10 can flow into the room through the air outlet 12.

[0102] Furthermore, the air inlet 11 on the first side panel 17 of the casing 10 is connected to the vent 2001 on the wall 200, so that the outdoor air can flow through the vent 2001 on the wall 200 and the air inlet 11 of the casing 10 in sequence, and then enter the interior of the casing 10, so that the computer room air conditioner 100 can be installed indoors.

[0103] According to other embodiments of the present invention, the second side panel 18 of the casing 10 is installed in close contact with the wall 200. In order to ensure that outdoor air can enter the room smoothly, the casing 10 needs to be installed outside the machine room. This can ensure that the air inlet 11 on the second side panel 18 of the casing 10 is located outdoors, so that outdoor air can flow into the casing 10 through the air inlet 11.

[0104] Furthermore, the air outlet 12 on the second side panel 18 of the casing 10 is connected to the vent 2001 on the wall 200. This ensures that the outdoor air entering the casing forms a heat exchange airflow and then flows into the computer room through the air outlet 12 on the casing 10 and the vent 2001 on the wall 200 in sequence, thereby enabling the computer room air conditioner 100 to be installed outdoors.

[0105] With such arrangement, the computer room air conditioner 100 in the embodiment of the present invention can meet the requirements of indoor and outdoor installation by forming the air inlet 11 and the air outlet 12 on opposite sides of the casing 10 in the first direction.

[0106] According to an embodiment of the present invention, the windward surface of the heat exchanger 20 is parallel to the first side panel 17 and / or the second side panel 18 of the casing 10, the heat exchanger 20 and the fan 30 are spaced apart in the second direction, and the air inlet 11 and the air outlet 12 are spaced apart in the second direction.

[0107] Specifically, the heat exchanger 20 is extended along the second direction near the air inlet 11 in the casing 10, so that the windward surface area of ​​the heat exchanger 20 can be maximized, which is beneficial to improving the heat exchange efficiency and the cooling efficiency of the computer room air conditioner 100.

[0108] In some embodiments of the present invention, the heat exchanger 20 is parallel to the first side panel 17 of the casing 10, and the side of the heat exchanger 20 adjacent to the air inlet 11 is the windward side of the heat exchanger 20. When the second side panel 18 is installed in close contact with the wall 200, the maximum windward side of the heat exchanger 20 can be guaranteed, which is beneficial to increase the contact area between the windward side of the heat exchanger 20 and the outdoor air, thereby helping to improve the heat exchange efficiency between the air and the refrigerant.

[0109] In other embodiments of the present invention, the heat exchanger 20 is parallel to the second side panel 18 of the casing 10, and the side of the heat exchanger 20 adjacent to the air inlet 11 is the windward surface of the heat exchanger 20. When the second side panel 18 is installed in close contact with the wall 200, the maximum windward surface of the heat exchanger 20 can be guaranteed, which is beneficial to increase the contact area between the windward surface of the heat exchanger 20 and the outdoor air, thereby helping to improve the heat exchange efficiency between the air and the refrigerant.

[0110] In some further embodiments of the present invention, the first side panel 17 and the second side panel 18 are opposite sides of the housing 10 in a first direction, and the heat exchanger 20 is parallel to the first side panel 17 and the second side panel 18 of the housing 10. When the computer room air conditioner 100 is installed indoors, the first side panel 17 of the housing 10 is installed flush with the wall 200, thereby ensuring that the heat exchanger 20 remains parallel to the wall 200. When the computer room air conditioner 100 is installed outdoors, the second side panel 18 of the housing 10 is installed flush with the wall 200, thereby ensuring that the heat exchanger 20 remains parallel to the wall 200. With this arrangement, whether the computer room air conditioner 100 is installed indoors or outdoors, the heat exchanger 20 remains parallel to the wall 200. This ensures that the windward surface of the heat exchanger 20 has a larger contact area with the outdoor air, thereby ensuring higher heat exchange efficiency of the heat exchanger 20 and, in turn, better cooling performance of the computer room air conditioner 100.

[0111] The heat exchanger 20 and the fan 30 are spaced apart in the second direction. In this way, the heat exchanger 20 and the fan 30 can be arranged simultaneously in the casing 10 without increasing the size of the computer room air conditioner 100 in the first direction. The heat exchanger 20 can be arranged adjacent to the air inlet 11, and the fan 30 can be arranged adjacent to the air outlet 12. In this way, the heat exchange airflow in the computer room air conditioner 100 can be ensured to flow from the air inlet 11 to the air outlet 12.

[0112] The air inlet 11 and the air outlet 12 are at least partially staggered with each other in the second direction, so that the heat exchanger 20 and the fan 30 can be arranged at least partially staggered with each other in the second direction. On the one hand, this can prevent the heat exchanger 20 and the fan 30 from occupying too much space in the second direction of the computer room air conditioner 100, thereby helping to reduce the size of the computer room air conditioner 100 in the second direction, and facilitating the arrangement of the computer room air conditioner 100 in the narrow installation space of the computer room. On the other hand, it is conducive to forming a stable heat exchange airflow in the casing 10 to improve the air outlet uniformity of the computer room air conditioner 100.

[0113] In an embodiment of the present invention, the first direction and the second direction are perpendicular to each other.
