Specifically, the ratio of the dimension L1 of the first air duct in the length direction of the casing 10 to the length dimension L of the casing 10 ranges from greater than 0.5 to less than 0.7, and preferably the ratio is 0.618. The ratio of the dimension L2 of the second air duct in the length direction of the casing 10 to the length dimension L of the casing 10 is greater than 0.3 and less than 0.5, and preferably the ratio is 0.382.

Further, the maximum distance dimension between the guide ring 321 of the second fan 32 and the condenser 50 is L3, and the ratio of L3 to the dimension L2 of the second air duct in the length direction of the casing 10 is greater than 0.2 and less than 0.4, preferably The ratio is 0.3.

Another aspect of the present invention also proposes a data processing device, which includes an equipment box and an air conditioner 1 . The air conditioner 1 may be the air conditioner 1 of any one of the above embodiments. There are power devices in the equipment box, and the power devices will generate a certain amount of heat when they work. normal operating state. The equipment box in this embodiment may be any one of a chassis or a cabinet.

According to the air conditioner of the present invention, the casing 10 is divided into the first chamber and the second chamber which are not connected to each other by the partition plate 20, the first air duct is arranged in the first chamber, and the first air duct is arranged in the first air duct. A fan 31 and an evaporator 40, a second air duct is arranged in the second chamber, and a second fan 32 and a condenser 50 are arranged in the second air duct, and the evaporator 40 and the condenser 50 cooperate to cool the casing At the same time, the evaporator 40 is installed between the first fan 31 and the first air return port 111, and the condenser 50 is installed between the second fan 32 and the second air return port 151, so that the inside of the shell 10 can be used reasonably. space, avoids additional space for installing the evaporator 40 and the condenser 50 in the housing 10, effectively reduces the overall size of the housing 10, thereby reducing the space occupancy rate of the air conditioner 1 in the equipment box .

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
