DESCRIPTION OF THE EMBODIMENTS
FIG. 1 is a schematic diagram of a motherboard module according to first embodiment of the disclosure, FIG. 2 is an exploded diagram of the motherboard module of FIG. 1, and FIG. 3 is a diagram of the cover in the motherboard module of FIG. 2 in another angle of view. Referring to FIGS. 1-3, in an embodiment, the motherboard module 100 includes a motherboard 110, a cover 120, a plurality of raised posts 130, a plurality of plates 140 and a plurality of electronic components 150 disposed on the motherboard 110. Although in the embodiment, the electronic components 150 are multiple ones, but the disclosure does not limit the quantity of the electronic components 150, and they can be south-bridge chip, north-bridge chip, network chip, graphic processing unit, audio chip, capacitor, resistor, or other relevant parts disposed on the motherboard 110, which the disclosure is not limited to.
The cover 120 covers the motherboard 110 thereon and together with the motherboard 110 forms a first space S1. The cover 120 herein can cover the motherboard 110 and the electronic components 150 on the motherboard 110 so as to provide the motherboard 110 with a succinct appearance. Moreover, the cover body 120 can also be designed with appropriate riffled figures, patterns or other decorations thereon to further make the appearance of the motherboard module 100 nicer. After the cover 120 covers the motherboard 110 and the electronic components 150, the user will not accidentally touch many sharps to get injured and the electronic components 150 will not contact the human-body or other conductive objects so as to reduce the probability of electric shock with the user or damage of the electronic components 150.
In an embodiment, the electronic components 150 are located in the first space S1 between the cover 120 and the motherboard 110 and therefore the heat generated by the electronic components 150 must be properly expelled to avoid the heat burden of the motherboard module 100, in which the heat burden is increased by the cover 120 due to hindering the regular heat-dissipating. The heats generated by the heat sources, i.e., each of the electronic components 150, are not completely the same; in fact, they are somehow different from each other depending on the usage of the motherboard module 100. In this regard, in addition to expelling the heat, the disclosure should consider how to avoid the inter-affecting of the heats generated by different electronic components 150.
FIG. 4A is a diagram showing the assembling of the plates and the raised posts on the cover of FIG. 3 and FIG. 4B is an exploded diagram of the plates and the raised posts of FIG. 4A. Referring to FIGS. 3, 4A and 4B, in an embodiment, the raised posts 130 can be arranged in array on the cover 120 or arranged in array on the motherboard. The plates 140 are respectively detachably assembled to the raised posts 130 so that each of the plates 140 is connected between any two adjacent raised posts 130 and the plates 140 can form a modular baffle structure on the cover 120. As a result, the first space S1 is partitioned into a plurality of second spaces S2 by the modular baffle structure (in the figures, as an exemplary implementation, only partial plates 140 form a baffle structure).
In the embodiment, the plates 140 can be made of plastic or rubber with flexibility, so that when the cover 120 covers the motherboard 110 with interfering the electronic components 150, the cover 120 does not damage the electronic components 150. However, the above-mentioned materials of the plates 140 are example only, which the disclosure is not limited to.
FIG. 5 is a top view diagram of the motherboard module of FIG. 1, in which arrows represent air flowing directions in the spaces. Referring to FIGS. 1 and 5, in the embodiment, the cover 120 further includes a plurality of openings P1, P2, P3 and P4, in which the opening P4 is able to make the user conveniently install the electronic components 150 (for example, expansion card) onto the motherboard 110; the opening P3 is able to expose a connector 180 out of the cover 120 so that the position of the connector 180 can be at a glance and the user can easily electrically connect an external device (not shown) to the motherboard 110; the openings P1 and P2 can serve as an outlet and an inlet of the cooling air-flow of the motherboard module 100.
In more details, the motherboard module 100 further includes a fan 160 disposed on the motherboard 110 and facing the opening P1 to pump external air into the first space S1 via the opening P1 for producing a cooling air-flow. In order to make the cooling air-flow flowing through the electronic components 150 to be heat-dissipated, the plates 140 can be assembled to the corresponding raised posts 130 to form a baffle structure. By using the second spaces S2 formed by the partition of the baffle structure, a plurality of air flowing channels are formed, which enables guiding the cooling air-flow from the outlet of the fan 160 to the electronic components 150, and then, the cooling air-flow flows out from the opening P2 of the cover 120 for cooling.
As description above, since the heats generated by the electronic components 150 are different depending on the usage of the motherboard 110, the above-mentioned baffle structure does not stay unchanged. However the plates 140 of the disclosure are detachably assembled onto different raised posts 130, it provides the user with a preference that when the usage state of the motherboard 110 is changed, the baffle structure can be accordingly revised by the user according to the present heats generated by the electronic components 150 (i.e., changing the channels of guiding the cooling air-flow). As a result, the motherboard module 100 of the disclosure has better adaptation.
In an embodiment, the baffle structure with different arrangement types can be directly formed on the cover, and in adaption to different motherboards or different electronic components, there are the corresponding cover and baffle structure to enable the motherboard module having better cooling efficiency.
FIG. 6 is a top view diagram of a motherboard module according to second embodiment of the disclosure. Referring to FIG. 6, since the heat generated by each of the electronic components is different from each other, in the embodiment, the above-mentioned baffle structure can also serve as an isolating structure to prevent the heat spreading. For example, the heat generated by the electronic component 150A of the embodiment is larger than the heat of the electronic component 150B or 150C. At the time, the electronic component 150A of the embodiment can be considered as a heat source in the space, and therefore, in addition to using the plates 140A and 140B to respectively form a baffle structure so as to guide the cooling air-flow to the electronic component 150A for cooling, the above-mentioned baffle structures formed by the plates 140A and 140B can further hinder transmitting the heat generated by the electronic component 150A to the electronic components 150B and 150C to increase the heat burdens at the places the electronic components 150B and 150C are located at. In other words, the baffle structures formed by the plates 140A and 140B can restrict the electronic component 150A serving as a heat source in the enclosed sub-space and produce effective heat-isolating efficiency for the electronic components 150B and 150C in other sub-spaces.
Referring to FIGS. 4A and 4B, the plates 140A and 140B respectively have a plate body A1 and two bushing portions B1 and B2 at the two opposite sides of the plate body, in which the bushing portions B1 and B2 are configured to bush any two adjacent raised posts 130, so that the plate body A1 can be connected between two adjacent raised posts 130. It should be noted that in order to provide various combinations of the plates and the raised posts, the bushing portions can have difference heights relatively to the plate body A1 depending on the usage conditions. Taking FIGS. 4A and 4B as an example, by using the difference between the heights of the bushing portions B1 and B2 relatively to the bottom of the plate body A1, the plates 140A and 140B can function in association with each other when they are bushed on the same raised post 130.
FIGS. 7A-7D are schematic diagrams showing different assembling states of the plates and the raised posts according to an embodiment of the disclosure. In the embodiment of FIG. 7A, similar to the embodiment of FIGS. 4A and 4B, the heights of the bushing portions B1 of the four plates 140 relatively to the bottom of the plate body A1 are different from each other, so that the plates 140A and 140B matched on the same raised post 130 can function in association with each other.
In the embodiment of FIG. 7B, the unique from the embodiments is that the plates have different plate body lengths (transverse length of the plate body A1 is different from the transverse length of the plate body A2) so that the plate bodies A1 and A2 can be assembled to adapt the different distances between the raised posts 130.
In the embodiments of FIGS. 7C and 7D, the plate 140C has a bushing portion B3 and two plate bodies A3 and A4 at the two opposite sides of the bushing portion B3, in which the bushing portion B3 bushes the raised post 130 to make the plate bodies A3 and A4 located between the raised post 130 and an adjacent raised post 130. In this way, the disclosure provides a different type of the plate 140C from the above-mentioned ones, and such plates can be also used in association with each other or can be used in association with the plates 140A and 140B.
FIG. 8A is a schematic diagram of an electronic apparatus according to third embodiment of the disclosure and FIG. 8B is a local cross-sectional diagram from FIG. 8A. Referring to FIGS. 8A and 8B, the arrows between raised posts represent the air flowing direction in the space. In the embodiment, the electronic apparatus 10 is, for example, a computer device and includes a chassis 200 and a motherboard module 100 disposed therein. The motherboard module 100 is described in the above-mentioned embodiments, which is omitted to describe. The unique from the above-mentioned embodiments is that a third space S3 is formed between the cover 120 and the chassis 200, and the raised posts 130 and the plates 140 can be optionally disposed in the third space S3. In other words, the raised posts 130 and the plates 140 can be substantially disposed on the two opposite surfaces of the cover 120 to achieve partitioning space effect, and the raised posts 130 and the plates 140 disposed in the first space S1 are omitted to describe.
In the embodiment, a fan 160 is disposed on the motherboard 110 and partially goes through the opening P1. That is to say, the inlet of the fan 160 is located in the third space S3 and the outlet thereof is located in the first space S1. The raised posts 130 and the plates 140 located in the third space S3 are used in association with each other to form multiple baffle structures. In this way, the air in the third space S3 can flow into the fan 160 along the channels formed by the baffle structures. In the same way, the plates 140 can detachably bush the raised posts 130, so that the user can allow the cool air in the third space S3 flowing into the fan 160 along the formed channels according to the internal space layout of the electronic apparatus 10, which thereby can dissipate heat on the electronic components in the cover 120.
In the embodiment, the kind and the type of the plates to form the baffle structure are not limited by the disclosure. The user can use the corresponding raised posts and plates modified by the user self from the above-mentioned embodiments to form desired channels of the cooling air-flow or the baffles to isolate the heat transmission in modular design.
In summary, in the motherboard module and the electronic apparatus using the same of the above-mentioned embodiments, by using the raised posts disposed in the first space and the plates detachably assembled on the raised posts, a plurality of air flowing channels or baffles for isolating the heats of the heat sources are formed on the cover. The plates and the raised posts can guide the cooling air-flow to the electronic components to be cooled and restrict the heat generated by the heat sources at different limited areas, which is advantageous for the cooling air-flow to cool the heat sources and the motherboard module thereby has better cooling performance.
Since the plates are detachable ones, the user is able to form different combinations of the air channels or heat-isolating baffles corresponding to the application environments of the motherboard module by user self, which allows the motherboard module and the electronic apparatus using the same to have proper and corresponding cooling effects according to the running thereof and expands the adaptation of the motherboard module.
