Abstract

A heat dissipation system for cabinet servers supported on a raised floor includes a condenser, airflow adjusting apparatus, a controller, and a temperature sensor located at an air outlet of each cabinet server. The raised floor defines air outlets adjacent to each cabinet server. The adjusting apparatus are mounted to the raised floor and aligning with the air outlets. Each of the airflow adjusting apparatus includes a number of shielding members rotatable relative to the raised floor and aligning with the air outlets, and a motor electrically coupled to the controller. The temperature sensors are electrically coupled to the controller. The condenser generates cool air entering the raised floor through the air inlet, to enter the cabinet servers through the airflow adjusting apparatus and the air outlets. The controller controls the shielding members to rotate, to change the opening size of the air outlets of the raised floor.

2. The heat dissipation system of claim 1 , wherein the bracket comprises two opposite end plates and two opposite side plates connected between the end plates, the end plates and the side plates cooperatively bound the through hole, the plurality of shielding members is rotatably installed between the end plates along a direction parallel to the side plates.

3. The heat dissipation system of claim 2 , wherein the end plates define a plurality pairs of opposite shaft holes, each of the shielding members comprises a plate received in the through hole, two opposite shafts extending out from two ends of the plate and rotatably received in the shaft holes of a corresponding pair of the pairs of opposite shaft holes, and a gear fitted about one of the two opposite shafts, the gear of each of the plurality of shielding members is located outside a same one of the end plates, the gear and each adjacent gear mesh with each other, the motor comprises a drive gear meshing with only one gear of each of the airflow adjusting apparatus.

4. The heat dissipation system of claim 3 , wherein the bracket comprises a mounting plate extends out from one of the end plates adjacent to the gear and each adjacent gear, the motor comprises a main body mounted to the mounting plate.

5. The heat dissipation system of claim 2 , wherein the end plates define a plurality pair of opposite shaft holes, each of the shielding members comprises a plate received in the through hole, two opposite shafts extending out from two ends of the plate and rotatably received in the shaft holes of a corresponding pair of the pairs of opposite shaft holes, and a gear fitted about one of the two opposite shafts, the gear of each of the plurality of shielding members is located outside a same one of the end plates, the airflow adjusting apparatus further comprises a plurality of connecting gears each meshing with the gear and an adjacent gear, the motor comprises a drive gear meshing with one of the gear or the adjacent gear.

6. The heat dissipation system of claim 1 , wherein when the temperature of the temperature sensor of a respective one of the cabinet servers is less than the temperature of the temperature sensor of each other of the cabinet servers, the controller controls the shielding members below the respective one of the cabinet server to rotate, the opening size of the through hole of the corresponding airflow adjusting apparatus is decreased, to allow the airflow of the cool air flowing through the corresponding one of the air outlets of the raised floor to decrease.

7. A container data center, comprising:
