In accordance with features of the preferred embodiment, air moving device (AMD) packaging apparatus essentially allows for the placement of an AMD through a very small opening in an access side of a system, normally in the front or back of the system. Once in place the AMD then is provided in an optimal position for effective thermal cooling of a system. The AMD packaging apparatus includes a mechanical ramp or a linkage system for properly locating the AMD. The AMD packaging apparatus allows for not only the proper location but also for docking and positive retention of an entire system for quality and reliability. The AMD packaging apparatus includes multiple parts having selected sizes to accommodate generally all types of AMDs.
Having reference now to the drawings, in FIGS. 1 and 2, there is shown air moving device (AMD) packaging apparatus generally designated by the reference character 100 in accordance with the preferred embodiment. AMD packaging apparatus 100 includes an AMD carriage structure generally designated by the reference character 102 and an associated frame generally designated by the reference character 104 receiving the AMD carriage structure 102.
Referring also to FIG. 3, the AMD carriage structure 102 includes an AMD holder section (shown shaded) generally designated by the reference character 106 pivotally connected to a driver section generally designated by the reference character 108 by a pivot connection 110.
The associated frame 104 includes elongated slots 112, each of the slots 112 formed in an opposing sidewall 114 of the associated frame 104. The associated frame 104 is mounted in a housing of a system to be cooled, for example, as illustrated in FIGS. 4 and 5.
The opposing sidewalls 114 of the associated frame 104 are spaced apart by a set distance related to the size of the AMD carriage structure 102. The elongated slots 112 define cooperating tracks for receiving and positioning the AMD carriage structure 102 within a particular system housing.
Each of the AMD holder section 106 and the driver section 108 includes a respective pair of outwardly extending protrusions or posts 116, 118 slideably received within the cooperating tracks 112 in the associated frame 104 to position an AMD contained within the AMD holder section 106 in an operating position within the associated frame 104.
Each of the outwardly extending protrusions 116 of the AMD holder section 106 is located on an opposed sidewall 120 near a first end 122 of the AMD holder section 106. The first end 122 is inserted first within an access face portion generally designated by the reference character 124 of the associated frame 104. As shown, AMD holder section 106 includes a generally centrally located, circular opening 125 for receiving and retaining an AMD. Various different types and sizes of AMDs can be used, such as various tube axial fans and various blower can be used for the AMD, and AMD holder section 106 is suitably configured for a particular AMD.
It should be understood that the present invention is not limited to the illustrated AMD packaging apparatus 100. For example, various sizes for the AMD carrier structure 102, the associated frame 104, and the shape and location of AMD receiving opening 125 are selectively provided for various available AMDs to be used with AMD packaging apparatus 100.
The elongated slots 112 include a tapered opening 126 to facilitate slidingly receiving the outwardly extending protrusions 116 when the AMD carrier structure is first inserted and pushed into the associated frame 104. The elongated slots 112 include an elongated first portion 128 having a selected length related to a length of the driver section 108 and a ramp portion 130 having a selected length and angle generally related to a length of the AMD holder section 106 for positioning the AMD within the system to be cooled. The ramp portion 130 extends along a line from near an upper side 132 to a lower side 134 of the sidewalls 114 of the associated frame 104.
The outwardly extending protrusions 118 of the driver section 108 are located on opposed sides 140 of the driver section spaced apart from the pivot connection 110 to the AMD holder section 106. A distal end 142 opposite the pivot connection 110 of the driver section 108 extends beyond the access face portion 124 of the associated frame in the ADM operating position. The AMD carriage structure 102 easily is removed from the associated frame 104 by pulling on the distal end 142 of the driver section 108.
A connector generally designated by the reference character 150 connects the AMD contained within the AMD holder section 106 to a power source (not shown). Connector 150 is mounted onto the AMD holder section 106 near the pivot connection 110 of the AMD holder section 106 and the driver section 108.
Connector 150 is disposed near the upper side 132 of frame sidewalls 114 with the AMD carriage structure 102 inserted into the frame 104 with the AMD provided in an operating position within the associated frame 104, for convenient and easy connection with the power source. Connector 150 alternatively can be mounted onto the AMD holder section 106 near the first end 122 for mating, for example, with a power source located with a supporting surface for AMD packaging apparatus 100.
AMD packaging apparatus 100 optionally includes an active circuit card, for example mounted to connector 150, for enabling apparatus 100 to function as a smart device.
Each of the AMD carriage structure 102 and the associated frame 104 preferably is formed of an electrically nonconductive material, such as a rigid plastic material.
