The fan module according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.
Fig. 1 is a plan view of a fan module according to a first embodiment of the present invention, which can be applied to a network device such as a switch or a router.
As shown in fig. 1, the fan module 100 may include a plurality of fans 20 and cable connectors 41 connected to the fans 20. The cable connector 41 can be plugged into a main control board of the network device to electrically connect the fan 20 with the main control board. Thus, the main control board can provide power support and process control for the fan 20.
A plurality of fans 20 may be mounted on the same fan frame 30. Generally, the plurality of fans 30 on the same fan frame 30 are of the same type, all being blowing fans, or all being extracting fans.
The cable connector 41 includes a connector 40 and a plurality of wires 52, 54, 56. The connector 40 may include a plug end 43 and a terminal 45, wherein the plug end 43 is plugged into a corresponding connector on the main control board, and the terminal 45 is used for mounting and fixing a plurality of wires 52, 54, 56.
The plurality of conductors 52, 54, 56 may be divided into multiple groups depending on the signals and functions being transmitted. The number of wires included in each group may be one or more.
One of the groups is a control group, which includes a plurality of control wires 52, and each control wire 52 is connected between the fan 20 and the connector 40, and is used as a channel for transmitting power and signals between the main control board and the fan 20. The control signal of the main control board to the fan 20 and the feedback signal fed back to the main control board by the fan 20 are transmitted through the control wire 52.
The other group is an identification group, which includes one or more identification wires 54. The signal transmitted within the identification conductor 54 is associated with certain basic information or information of the fan 20 (e.g., the blowing characteristics of the fan, the supplier of the fan, etc.). By reading the signal in the identification wire 54, the main control board can determine the information related to the fan connected to the identification wire 54. Thus, the signal within the identification wire 54 may also be referred to as an identification signal.
The first end 543 of the identification wire 54 is connected to the terminal 45 of the connector 40 and is electrically connectable to the main control board through the connector 40. Further, the main control board may collect the identification signal in the identification wire 54 through a preset pattern, such as continuous collection, collection at certain time intervals, or collection at startup. As for the second end 545 of the identification lead 54, it may be selectively grounded or floating (i.e., not grounded) depending on certain basic information about an aspect of the fan 20 (e.g., the nature of the draw, the supplier, etc.).
For example, if the first type fan 20 is a blowing fan, the second end 545 of the identification wire 54 may be installed in a grounded manner; if the second type of fan 20 is an id fan, the second end 545 of the identification wire 54 may be installed in a non-grounded or floating manner.
After the fan 20 is mounted to the main control board, the main control board collects and reads the identification signal in the identification wire 54. If the level of the identification signal is found to be low, it indicates that the identification wire 54 is grounded, and it can be determined that the corresponding fan 20 is a blowing fan (a first type fan) accordingly. If the level of the identification signal is found to be high, it indicates that the identification wire 54 is not grounded, and accordingly, it can be determined that the corresponding fan 20 is an id fan (a second type of fan).
Similar approaches may also be used to identify other basic information about the fan, such as the supplier of the fan. For example, if the supplier of the first type of fan 20 is manufacturer a, the second end 545 of the identification wire 54 may be installed in a grounded manner; if the supplier of the second type of fan 20 is vendor B, the second end 545 of the identification wire 54 may be installed in a non-grounded or floating manner.
After the fan 20 is mounted to the main control board, the main control board collects and reads the identification signal in the identification wire 54. If the level of the identification signal is found to be low, it may be determined that the corresponding fan 20 is supplied by vendor a (a first type of fan). If the level of the identification signal is found to be high, it indicates that the corresponding fan 20 (fan of the second type) is supplied by the manufacturer B.
In other embodiments, the number of identification wires 54 may be multiple. Each identification wire 54 may correspond to a different aspect of the fan 20. For example, a first one may be used to identify whether the fan is an id fan or a blower fan, a second one may be used to identify whether the fan is supplied by vendor a or vendor B, a third one may be used to identify whether the expected life of the fan is not less than 5 years, and so on.
To facilitate installation of the second end 545 of the identification lead 54, a conductive connector may be provided at the second end 545 of the identification lead 54. The connector may be a conductive terminal 60 having a mounting hole therein, or may be an electrical connector 260 (see fig. 3).
A third set of wires may also be included in the plurality of wires 52, 54, 56. The third set of wires may include only one wire 56. The lead wire 56 is connected between the indicator lamp 70 and the connector 40, and serves as a channel for power and signal transmission between the main control board and the indicator lamp 70. For example, when the fan 20 is running, the main control board can control the indicator lamp 70 to light up or keep flashing; when the fan 20 is not running, the main control board can control the indicator lamp 70 to be turned off.
Fig. 2 is a perspective view of the fan module of fig. 1. As shown in fig. 2, the fan module 100 further includes a metal housing 80. The metal housing 80 is comprised of a plurality of walls (e.g., bottom wall 84) that cover at least a portion of the fan 20. Also, the metal case 80 is grounded. The metal casing 80 may be a part of the fan frame. After the metal housings 80 are mounted on the fan 20, they may be further fixed using rubber pins.
The wall 84 of the metal housing 80 may be provided with a ground mounting portion 845 and a suspension mounting portion 843, both of which may be used to mount the conductive terminal 60 on the metal housing 80. The conductive terminals 60 can be alternatively mounted on one of the ground mounting portion 845 and the suspension mounting portion 843. The grounding portion 845 is used for grounding the conductive terminal 60 to the metal housing 80, so that the conductive terminal 60 is electrically connected to the metal housing 80. The suspension mounting portion 843 can be used to mount the conductive terminal 60 on the metal housing 80 in a suspension manner, so that the conductive terminal 60 is not grounded.
The ground mounting portion 845 may be a mounting post of a metallic material, corresponding to the mounting hole structure of the conductive terminal 60. When the conductive terminal is installed, the mounting column group is installed in the mounting hole of the conductive terminal. In this embodiment, the grounding mounting portion 845 is a rivet pressing stud.
A mounting plate 847 may also be provided at the front end of the wall plate 84 for mounting and securing the connector 40.
Fig. 3 is a plan view of a fan module according to a second embodiment of the present invention. The main difference from the first embodiment is the connector (conductive terminal 60 in the first embodiment) disposed at the second end 545 of the identification lead 54 and the mating structure corresponding to the connector. Other structures may be the same or substantially the same as the corresponding structures in the first embodiment, and are not described herein again. The following description focuses on the connector and its corresponding mating structure provided at the second end 545 of the identification lead 54 in the second embodiment.
Please refer to fig. 3, and if necessary, refer to fig. 1 and 2 in combination. In the second embodiment, the connector disposed at the second end 545 of the identification lead 54 is not a conductive terminal having mounting holes disposed therein, but rather is an electrical connector 260. The electrical connector 260 may be a plug-type connector.
Correspondingly, the mating connector 90 may be a connector and has mating spaces 91, 92, 93 and 94 for receiving the electrical connector 260. The coupling spaces 91, 92, 93, 94 are independent of each other and can be regarded as a sub-connector.
Further, a connector 90 may be provided on the control wire 52. Take the mating space 91 thereon as an example.
One of the control wires 52 (the lower most control wire in fig. 3) is connected to the connector 40 at a first end and to the ground signal of the fan 20 at a second end. Since this control conductor 52 is associated with "ground", it is referred to herein as a "ground control conductor" in order to distinguish it from other control conductors. The mating space 91 is provided in the middle area of the ground control lead 52 and is in electrical communication with the ground control lead 52.
Accordingly, by plugging the electrical connector 260 into the mating space 91, grounding of the identification wire 54 can be achieved; the hanging of the identification wire 54 can be achieved by leaving the electrical connector 260 empty.
For example, when the fan 20 is a blowing fan, the electrical connector 260 may be inserted into the mating space 91 to ground the electrical connector 260; when the fan 20 is an exhaust fan, the electrical connector 260 can be inserted into the mating space 91 so that the electrical connector 260 is not grounded. The subsequent main control board can identify the fan 20 as a blowing fan or an extracting fan by detecting and identifying the state change of the signal level.
There are many ways in which the mating space 91 can be electrically connected to the middle region of the ground control lead 52. For example, the middle region of the ground control wire 52 may be wound around the conductive contact of the mating space 91, i.e., the mating space 91 provided on the connector. For another example, the ground control wire 52 may be divided into two intermittent segments, the first segment may have two ends respectively connected to the connector 40 and the mating space 91, and the second segment may have two ends respectively connected to the mating space 91 and the ground signal of the fan 20. For another example, a wire may be led out from the mating space 91, and the electrical communication between the mating space 91 and the ground control wire 52 may be realized by overlapping the wire to the middle region of the ground control wire 52.
In addition to the adapter space 91, further adapter spaces 92, 93, 94 can be connected to corresponding signals of the fan via corresponding control lines 52. For example, the adapting space 92 can be electrically connected to the fan speed control signal through the corresponding control wire 52; the adapting space 93 can be electrically connected with the fan speed feedback signal through the corresponding control wire 52; the mating space 94 may be electrically connected to the fan power signal via the corresponding control wire 52.
Similarly, by selectively inserting or not inserting the electrical connector 260 into the mating space 92, the mating space 93 and the mating space 94, the main control board can also recognize the information of the fan in the corresponding aspect.
Fig. 4 is a plan view of a fan module according to a third embodiment of the present invention. The main difference from the second embodiment is in identifying the number of the conductive lines 54. Other structures may be the same or substantially the same as the corresponding structures in the second embodiment, and are not described here again.
As shown in fig. 4, the number of the identification wires 54 may be plural, four in the present embodiment. The second end of each identification wire 54 is provided with an electrical connector 261, 262, 263 and 264. Which are each used to identify different aspects of the fan. Identification of information regarding the various aspects of the fan may be accomplished by selectively inserting or not inserting the electrical connectors 261, 262, 263, 264 into the corresponding mating spaces 91, 92, 93, 94, or by inserting the electrical connectors 261, 262, 263, 264 into the different mating spaces 91, 92, 93, 94.
Correspondingly, the invention also provides a fan information identification method. The fan information identification method is applied to network equipment comprising the fan module, and comprises the following steps:
the main control board collects identification signals in the identification wires;
and determining and outputting the information of the fan according to the identification signal.
Further, determining information of the fan according to the identification signal includes:
if the level of the identification signal is low level, determining that the fan is a first type fan; and if the level of the identification signal is high level, determining that the fan is a second type fan.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
