Abstract
Disclosed is a heat dissipation subrack, including a cabinet body defining an accommodating space. The cabinet body defines an air inlet, two air supplementing openings, and an air outlet. The accommodating space has an air inlet region, and a heat source region communicatively coupled to the air inlet region. An opening direction of the air inlet and an opening direction of each of the air supplementing openings intersect in the air inlet region. The cabinet body includes multiple baffles, each of the baffles includes two wind shielding surfaces, and airflow passages are defined between each two adjacent baffles and between one of inner walls of the cabinet body and an baffle adjacent to the one of the inner walls of the cabinet body.
Claims19
A heat dissipation subrack, comprising a cabinet body defining an accommodating space, wherein the cabinet body defines an air inlet, two air supplementing openings, and an air outlet, wherein:
- the accommodating space has an air inlet region directly facing the air inlet and the two air supplementing openings, and a heat source region communicatively coupled to the air inlet region;
- wherein the air inlet has a first opening direction, each of the two air supplementing openings has a second opening direction, and the first opening direction and the second opening direction intersect in the air inlet region;
- and
- the cabinet body comprises baffles disposed in the air inlet region and spaced apart from one another, wherein each of the baffles comprises two wind shielding surfaces, one of the two wind shielding surfaces faces one of the two air supplementing openings, the other of the two wind shielding surfaces faces the other of the two air supplementing openings, and areas of the wind shielding surfaces of the baffles increase sequentially along a direction away from the air supplementing openings, wherein airflow passages facing the air inlet and communicatively coupling the air inlet region to the heat source region are respectively defined between each two adjacent baffles as well as between one of inner walls of the cabinet body and the baffle adjacent to the one of the inner walls of the cabinet body.
A heat dissipation cabinet, comprising two heat dissipation subracks, wherein each of the two heat dissipation subracks comprises:
- a cabinet body defining an accommodating space, wherein the cabinet body defines an air inlet, two air supplementing openings, and an air outlet, wherein
- the accommodating space has an air inlet region directly facing the air inlet and the two air supplementing openings, and a heat source region communicatively coupled to the air inlet region;
- wherein the air inlet has a first opening direction, each of the two air supplementing openings has a second opening direction, and the first opening direction and the second opening direction intersect in the air inlet region;
- and
- the cabinet body comprises baffles disposed in the air inlet region and spaced apart from one another, wherein each of the baffles comprises two wind shielding surfaces, one of the two wind shielding surfaces faces one of the two air supplementing openings, the other of the two wind shielding surfaces faces the other of the two air supplementing openings, and areas of the wind shielding surfaces of the baffles increase sequentially along a direction away from the air supplementing openings, wherein airflow passages facing the air inlet and communicatively coupling the air inlet region to the heat source region are respectively defined between each two adjacent baffles as well as between one of inner walls of the cabinet body and the baffle adjacent to the one of the inner walls of the cabinet body;
- wherein the cabinet body of one of the two heat dissipation subracks is stacked on the cabinet body of the other of the two heat dissipation subracks.
A backplane communication system, comprising at least one backplane, at least one heating element disposed on the at least one backplane, and a heat dissipation subrack, wherein the at least one backplane is disposed in an accommodating space, wherein the heat dissipation subrack comprises:
- a cabinet body defining the accommodating space, wherein the cabinet body defines an air inlet, two air supplementing openings, and an air outlet, wherein
- the accommodating space has an air inlet region directly facing the air inlet and the two air supplementing openings, and a heat source region communicatively coupled to the air inlet region;
- wherein the air inlet has a first opening direction, each of the two air supplementing openings has a second opening direction, and the first opening direction and the second opening direction intersect in the air inlet region;
- and
- the cabinet body comprises baffles disposed in the air inlet region and spaced apart from one another, wherein each of the baffles comprises two wind shielding surfaces, one of the two wind shielding surfaces faces one of the two air supplementing openings, the other of the two wind shielding surfaces faces the other of the two air supplementing openings, and areas of the wind shielding surfaces of the baffles increase sequentially along a direction away from the air supplementing openings, wherein airflow passages facing the air inlet and communicatively coupling the air inlet region with the heat source region are respectively defined between each two adjacent baffles as well as between one of inner walls of the cabinet body and the baffle adjacent to the one of the inner walls of the cabinet body.
