Casing for reducing airflow resistance, cooling device, and server using the same
View Patent ↗A cooling device applied to a server or other casing reduces airflow resistance. A covered chassis defines a accommodating groove and includes two opposite ends, an air inlet located at one end and an air outlet located at the other end, the air outlet communicating with the air inlet. The cover of the chassis is mounted adjacent a side of the chassis and seals the accommodating groove. The cover defines first and second openings corresponding to the accommodating groove. Part of cooling air exits the casing through the accommodating groove and the air outlet, the rest of the cooling air exits the casing through the first opening, re-enters the casing through the second opening and exits the casing through the air outlet.

6. The casing of claim 1 , wherein the chassis is a cuboid box with an open side, and the cover is mounted adjacent the open side of the chassis; and the air inlet and the air outlet are located at two opposite ends of the length direction of the cuboid box.
7. The casing of claim 1 , wherein the first opening and the second opening are rectangular openings of same width, and the length of the first opening is larger than the length of the second opening.
8. A cooling device comprising:
a casing for reducing airflow resistance, comprising:
a chassis defining a accommodating groove configured to accommodate electronic components, the chassis comprises two opposite ends and:
an air inlet located at one end of the chassis; and
an air outlet located at the other end of the chassis and is in fluid communication with the air inlet; and
a cover mounted adjacent a side of the chassis, the cover defines a first opening and a second opening, the first opening and the second opening are corresponding to the accommodating groove and in fluid communication with the accommodating groove; and
a cooling fan mounted adjacent the air inlet or the air outlet;
wherein cooling air gets into the accommodating groove through the air inlet, and a part of the cooling air exits the casing through the accommodating groove and the air outlet, the rest of the cooling air exits the casing through the first opening, and gets into the casing again through the second opening and exits the casing through the air outlet.
9. The cooling device of claim 8 , wherein the casing further comprises a solid block attached to an inner surface of the cover, and the solid block is corresponding to the accommodating groove.
10. The cooling device of claim 9 , wherein the solid block is located between the first opening and the second opening.
11. The cooling device of claim 8 , wherein the chassis further comprises a first mounting members configured to mount a hard disks, and the first mounting members are fixed in the accommodating groove.
12. The cooling device of claim 8 , wherein the chassis further comprises a second mounting member configured to mount a cooling fan, and the second mounting member is fixed in the air outlet.
13. The cooling device of claim 8 , wherein the chassis is a cuboid box with an open side, and the cover is mounted adjacent the open side of the chassis; the air inlet and the air outlet are located at two opposite ends of the length direction of the cuboid box.
14. The cooling device of claim 8 , wherein the first opening and the second opening are rectangular openings of same width, and the length of the first opening is larger than the length of the second opening.
15. A server comprising:
a hard disks; and
a cooling device for cooling the hard disks, comprising:
a casing for reducing airflow resistance, comprising:
a chassis defining a accommodating groove configured to accommodate electronic components, the chassis comprises two opposite ends and:
an air inlet located at one end of the chassis; and
an air outlet located at the other end of the chassis and is in fluid communication with the air inlet; and
a cover mounted adjacent a side of the chassis and configured to seal the accommodating groove, the cover defines a first opening and a second opening, the first opening and the second opening are corresponding to the accommodating groove and in fluid communication with the accommodating groove; and
a cooling fan mounted adjacent the air inlet or the air outlet;
wherein cooling air gets into the accommodating groove through the air inlet, and a part of the cooling air exits the casing through the accommodating groove and the air outlet, the rest of the cooling air exits the casing through the first opening, and gets into the casing again through the second opening and exits the casing through the air outlet.
16. The server of claim 15 , wherein the casing further comprises a solid block attached to an inner surface of the cover, and the solid block is corresponding to the accommodating groove.
