In order to reduce the impact of the internal temperature of the room on the equipment and ensure the normal operation of the equipment, the room is usually cooled and refrigerated.

[0003] At present, computer rooms are generally equipped with comfort air conditioners to control the internal temperature of the computer rooms. Although this cooling method can meet the cooling and refrigeration requirements of the computer room, when the outdoor temperature is lower than the internal temperature of the computer room, it is unable to fully utilize the external cold source to cool down the interior of the computer room. It only relies on air conditioning to maintain the ambient temperature of the computer room, which consumes a lot of energy, easily causes energy waste, and increases operating costs.

[0004] Therefore, in view of the above problems, it is urgent to provide an energy-saving heat exchange device for a computer room that can perform reasonable and energy-saving cooling according to the outdoor temperature. Utility Model Content

When the device is not in use, the mounting seat 2 is covered with the protective shell 20 to seal the air duct 4 to prevent foreign matter from entering the air duct 4. Entering, the two air ducts 4 are jointly provided with four baffles 6 arranged in a transverse direction, and the baffles 6 are used to change the flow direction of the air entering the interior of the shell 1 and reduce the flow speed, so as to improve the air heat exchange effect when in use, and the top and bottom of the baffles 6 are provided with mounting plates 5, and the mounting plates 5 are used to fix the baffles 6 inside the shell 1. The front side of the shell 1 is embedded with a second fan 7 and an exhaust fan 9, and the second fan 7 and the exhaust fan 9 are respectively distributed on the right and left front sides of the shell 1.

[0031] First, according to the outdoor temperature, select the heat exchange mode and the ordinary air conditioning mode for cooling. When the outdoor temperature is lower than the indoor temperature of the machine room, turn on the heat exchange mode, and the first fan 3 and the second fan 7 of the upper air duct 4 are started at the same time to draw the outdoor cold air and the indoor air of the machine room into the air duct 4 and the shell 1 respectively for heat exchange without crossover, so that the outdoor cold air in the air duct 4 absorbs the heat of the indoor air and is discharged to the outside, and the cooled air is re-discharged into the machine room through the exhaust fan 9, thereby lowering the indoor air temperature while maintaining the cleanliness of the original indoor air, and reducing The energy consumption of the computer room air conditioner is reduced to achieve energy-saving effect.
