No. 62/158,529 titled Server Rack with Integrated Precision Air Flow filed on May 7, 2015.
- The present disclosure relates to a computer server rack and more particularly, a computer server rack system that can be used to efficiently direct air flow to electric equipment such as servers and other network devices for dissipation of heat.
- Existing rack-mount server systems include a server rack and a plurality of server units received in the server rack. Typically each of the server units is mounted to the server rack with a pair of mounting brackets or rails respectively fixed to the inside surface of opposite sidewalls of a server rack. There have been numerous efforts to direct air and other fluids to electronic equipment to aid in heat dissipation.
- The server rack according to the invention includes a frame that includes hollow tubular support posts on the front sides and rear sides of the device. Between the front and rear posts are forward side panels and rearward side panels. The panels receive a complement of cartridges that have valve members to control the flow of air from a rear cavity though passages in the cartridges, through the rail and into servers. A plurality of side rails for receiving servers are attached to the front and rear posts. The rails have passages through the sidewalls that correspond with passages provided on the sidewalls of the servers.
- In a preferred embodiment, air conditioned air is introduced to forward side panels through passages provided on the upper and lower surfaces. Next, air travels from the forward panel, though one or more passages that is provided through a cartridge member, and then, into a front section of a server through a passage that is provided on the lateral sidewall of the server. Air travels through the server from the front section of the server to a rear section and then exits through a passage in the lateral sidewall to a cartridge that is provided in a rear panel. Next the air is returned to the air conditioner unit for recirculation.
- In an embodiment the sever rack is approximately 6 feet tall and designed to accommodate forty-two server units in 4.445 cm (1.75 inch) increments. Rail members are provided at each unit segment on the side panels and support a server. In embodiments further discussed below, passages through the cartridges have at least one valve member that can be individually electromechanically or manually controlled. When no server is provided in a specific rack unit, or when the temperature is otherwise adequately controlled in a particular server unit, the aperture may be closed. In embodiments, a controller automatically opens or closes valve members provide in cartridges in response to a signal from a thermometer.
- As such, it should be appreciated that the valves or passages can be opened and closed variably for each server depending on the cooling needs for the server. Further, as discussed herein, the degree of air flow through the aperture can be controlled using a damper or weir arrangement. Therefore, in embodiments, a local controller is provided and can receive input information from thermometers reading the temperatures of the servers and can adjust the opening and closing valves aperture accordingly. Alternatively the dampers may be manually adjusted. In yet further embodiments a central controller receives signals from a plurality of server racks.
- Each of the openings on the post is provided with a releasable seal to block flow depending on the particular configuration of servers. In embodiments, flexible manifolds extend from the posts to direct the fluid to and from access areas provided on the servers. While the preferred embodiment contemplates the use of air flow, in embodiments the frame is configured to receive a liquid and the posts and manifold direct fluid to heat exchange elements that engaged the respective servers.
- In yet further embodiments the rack is configured to allow both liquid flow and air flow.
- These aspects of the invention are not meant to be exclusive. Furthermore, some features may apply to certain versions of the invention, but not others. Other features, aspects, and advantages of the present invention will be readily apparent to those of ordinary skill in the art when read in conjunction with the following description, and accompanying drawings.
