Reversible fan module for electronic enclosures
View Patent ↗An enclosure for electronics includes a chassis and an interface connector positioned within the chassis and configured to provide power. A fan shelf module is received within the chassis and has at least one fan to provide air flow through the chassis. The fan shelf module includes a pinout connector along a horizontal or vertical line of symmetry and configured to engage the interface connector and receive power therefrom, such that the fan shelf module is selectively installed in one of two opposing directions allowing a fan air flow direction to the chassis to be selected as either pulling air or pushing air through the chassis depending on the installed direction of the fan shelf module.
1. An enclosure for electronics, comprising;
an interface connector within the enclosure to provide power; and
a fan module within the enclosure and comprising a pinout connector lying along a horizontal or vertical line of symmetry;
the pinout connector engaging said interface connector to receive power therefrom, wherein said pinout connector comprises a planar configured tab having electrical terminals that are symmetrically arranged on top and bottom allowing the pinout connector to be received within said interface connector in either opposing directions and permitting power to be drawn therefrom.
2. The enclosure according to claim 1 , wherein said enclosure comprises a one rack-unit height.
3. The enclosure according to claim 1 , wherein said fan module comprises a plurality of serially mounted fans.
4. The enclosure according to claim 1 , wherein said symmetrically arranged electrical terminals comprise dual ground and power terminals.
5. The enclosure according to claim 1 , and further comprising a plurality of electronic modules received within said enclosure and configured to receive electronic components and to receive the airflow created by the fan module.
6. The enclosure according to claim 5 , wherein said electronic modules comprise vertical partition members spaced parallel from each other and each configured to receive and support said electronic modules.
7. The enclosure according to claim 6 , wherein said enclosure is substantially rectangular configured and includes an end that receives the fan module, and said plurality of electronic modules are received in parallel to each other and to the fan module.
8. The enclosure according to claim 1 , the fan module is selectively installable in one of two opposing directions enabling a fan air flow direction through the enclosure to be selected as either pulling air or pushing air through the enclosure depending on the installed direction of the fan module.
9. A method of providing an airflow through an enclosure for electronics, comprising:
selectively installing a fan module in the enclosure in one of two opposing directions; and
engaging a pinout connector lying along a horizontal or vertical line of symmetry of the fan module with an interface connector of the enclosure enabling a fan air flow direction through the enclosure to be selected as either pulling air or pushing air through the enclosure dependent on the installed direction of the fan module, wherein the pinout connector comprises a planar configured tab having electrical terminals that are symmetrically arranged on top and bottom, and further comprising receiving the pinout connector within the interface connector in either opposing directions and drawing power therefrom.
10. The method according to claim 9 , wherein said enclosure includes a fixed module frame having a receiving slot and a guide edge and the fan module includes a fan shelf tab and a support track, and further comprising installing the fan module within a first direction by sliding the fan shelf tab within the receiving slot and providing air flow in a first direction and installing the fan module in a second opposing direction by reversing orientation of the fan module and sliding the support track over the guide edge and providing air flow in reverse direction.
11. The method according to claim 9 , wherein the symmetrically arranged electrical terminals comprise dual ground and power terminals.
12. The method according to claim 9 , wherein the enclosure is substantially rectangular configured and comprises an end that receives the fan module, and further comprising receiving a plurality of electronic modules in parallel to each other and to the fan module.
13. A fan module, comprising:
at least one fan to provide airflow through an enclosure;
a pinout connector lying along a horizontal or vertical line of symmetry; and
the pinout connector configured to engage an interface connector within the enclosure to receive power therefrom, wherein said pinout connector comprises a planar configured tab having electrical terminals that are symmetrically arranged on top and bottom allowing the pinout connector to be received within said interface connector in either opposing directions and permitting power to be drawn therefrom.
14. The fan module of claim 13 , wherein said fan module comprises a plurality of serially mounted fans.
15. The fan module of claim 13 , wherein said symmetrically arranged electrical terminals comprise dual ground and power terminals.
16. The fan module of claim 13 , wherein the fan module can be selectively installed in one of two opposing directions allowing a fan air flow direction through the enclosure to be selected as either pulling air or pushing air through the enclosure depending on the installed direction of the fan module.
