Description

[Technical field]

[0001] The present invention relates to a pre-intercepting device, and more particularly to a pre-intercepting device and a filtering system of an electronic device using the pre-intercepting device. [Background technology]

[0002] There may be many tiny foreign objects (such as dust, fibers, metal debris, metal powder particles, etc.) in the use environment of electronic devices. These tiny foreign objects are in the form of particles, granules, flakes or blocks and must be blocked as much as possible (especially metal debris and metal powder particles with conductive properties) to prevent these foreign objects from being sucked into the interior of the electronic device along with the operation of the electronic device's cooling system or other systems, further causing equipment failure or damage.

[0003] Among them, although the filter-type filtration system can play an excellent foreign matter blocking effect, it also causes the accumulation of foreign matter quite quickly, so the filter must be replaced frequently, otherwise it will affect the air intake of electronic equipment due to blockage, thereby reducing the heat dissipation efficiency. On the other hand, too frequent filter replacement also leads to increased costs and inconvenience in use. [Summary of the invention]

[0004] In the pre-intercepting device of some embodiments of the present invention and the filtering system using the pre-intercepting device, an intercepting device configured by utilizing the physical properties of foreign matter is provided to provide a filtering effect on the fluid passing therethrough.

[0005] According to some embodiments, a pre-intercepting device is provided for intercepting foreign matter from a passing fluid, and the pre-intercepting device comprises: an input portion for fluid inflow, an output portion for fluid outflow, a plurality of branch flow channels, and a plurality of intercepting portions. Each branch flow channel connects the output portion and the input portion, and is used to provide a turning guide for the flow of the fluid, and each branch flow channel has a fluid lifting section. These intercepting portions are arranged at the path edge of the fluid lifting section of each branch flow channel, so that at least a portion of the fluid flowing through the branch flow channel can flow through the corresponding intercepting portion to form a turbulent flow field. This turbulent flow field can capture foreign matter flowing through the branch flow channel in the intercepting portion.

[0006] According to some embodiments, each branch flow channel may have a first opening configured at the input part and a second opening configured at the output part, wherein the first opening is lower than the second opening, the fluid lifting section is located between the first opening and the second opening, and the corresponding intercepting portion is configured adjacent to the second opening and located at the lower side of the second opening.

[0007] According to some embodiments, it may include: a plurality of spacers stacked at intervals. The front section of such spacers defines an input portion, the rear section of such spacers defines an output portion, and a flow channel is defined between two adjacent spacers. The rear section of each spacer has a folded portion extending upward and then convex forward to form an interception portion.

[0008] According to some embodiments, the front section of each spacer may have a portion extending vertically downward to form a portion of the input portion together with other adjacent spacers.

[0009] According to some embodiments, the front section of each spacer may have an eave portion extending obliquely downward and outward, so as to be configured as a partial input portion together with other adjacent spacers.

[0010] According to some embodiments, a filtering system for an electronic device is provided, which includes: a pre-intercepting device and a filter; the pre-intercepting device includes: an input part for fluid to flow in, an output part for fluid to flow out and flow to the inside of the electronic device, a plurality of branch flow channels and a plurality of intercepting parts; the branch flow channels are used to provide turning guidance for the flow of the fluid, and the branch flow channels individually connect the output part and the input part, and each branch flow channel has a fluid lifting section; the intercepting part is arranged at the path edge of the fluid lifting section of each branch flow channel, and is used to make at least a part of the fluid flowing through the branch flow channel flow through the corresponding intercepting part to form a turbulent flow field; the filter is arranged on the outside of the output part, and is used to allow the fluid flowing to the inside of the electronic device to pass through.

[0011] In this way, based on the physical properties of foreign matter and by controlling the flow direction and flow field of the fluid, foreign matter with some special physical properties (such as: heavier weight or larger volume, etc.) can be captured by the front interception device, and such a front interception device has the advantage of low cost. In addition, when a filter is configured at the rear end of the flow channel, the burden of the filter can be reduced and the service life of the filter can be extended.

[Specific implementation method]

[0013] In order to fully understand the purpose, features and effects of the present invention, the present invention is now described in detail with the help of the following specific embodiments and the accompanying drawings, as follows:

[0014] In an embodiment of the present invention, the flow direction change caused by the fluid flowing in the flow channel of the front interception device allows some foreign matter in the fluid to be captured in the additional turbulent flow field due to inertia during the flow direction change based on physical properties, thereby achieving the interception effect. The foreign matter involved refers to objects that are expected to be excluded, including solids that are mixed in the fluid and are expected to be excluded as much as possible, such as dust, fibers, metal debris, metal powder particles, etc. The fluid involved, for example, may include: gas or a liquid-gas mixture.

[0015] Please refer to Figure 1 , which is a partial cross-sectional schematic diagram of a front interception device according to some embodiments. Figure 1 The example of a part of the front interception device 1 includes an interception portion 40 and a flow diversion channel 30 having a fluid lifting section 12. The interception portion 40 is disposed on one side of the flow diversion channel 30, adjacent to the path edge of the fluid lifting section 12, so as to cause the fluid to generate disturbances and have a rotating vortex, so that the fluid forms a turbulent flow field.

[0016] The combination of the plurality of flow diversion channels 30 and the interception parts 40 corresponding to the flow diversion channels 30 can construct the main part of the front interception device ( Figure 1 (not shown) to divert the passing fluid and provide foreign matter interception. Figure 1In the partial front interception device 1 shown, the diverted input fluid flows in from the input part 10 (forming the input fluid flow direction Fi), and forms the lifted fluid (forming the lifted fluid flow direction Fr) and turbulent fluid (forming the turbulent fluid flow direction Ft) in the fluid lifting section 12 and the interception part 40, and then is output by the output part 20 to form the output fluid (forming the output fluid flow direction Fo). The front end of each diverting flow channel 30 is connected to the input part 10 of the front interception device 1, and the rear end of each diverting flow channel 30 is connected to the output part 20 of the front interception device 1.

[0017] like Figure 1 The diversion channel 30 provides a turning guide for the fluid flowing through and constructs a fluid lifting section 12, and through the adjacent intercepting section 40, at least a part of the fluid flowing through forms a turbulent flow field therein. Such a configuration can provide a kind of attraction for foreign matter in the fluid. For example, some foreign matter can be easily deviated from the flow direction of the fluid lifting section 12 due to inertia during the flow direction change process due to its own physical properties such as large volume and / or heavy weight, and further captured in the intercepting section 40 based on the effect of the turbulent flow field, thereby achieving the intercepting effect of the intercepting section 40 on foreign matter.

[0018] Furthermore, when the foreign matter accumulated in the interception portion 40 reaches a certain amount, it needs to be cleaned. In order to keep the intercepted foreign matter in the interception portion 40 as much as possible and extend the cleaning cycle of the interception portion 40, the interception portion 40 can accumulate the intercepted foreign matter as much as possible through the shape and / or material configuration of the inner surface. For example, the bottom of the interception portion 40 further has a recessed portion for accommodating foreign matter and / or the bottom of the interception portion 40 further has a configuration that is easy to catch foreign matter (for example, a thorny structure on the bottom surface and / or providing a magnet that can attract metal, etc.).

[0019] Next, please refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 is a three-dimensional cross-sectional schematic diagram of a front interception device in a first implementation manner according to some embodiments, Figure 3 for Figure 2 A cross-sectional schematic diagram of an implementation method, Figure 4 for Figure 2 A three-dimensional schematic diagram of a rear side view under an implementation method.

[0020] The pre-intercepting device 100 in the first embodiment has stacked diversion channels 130, so that the fluid flowing into the pre-intercepting device 100 is diverted to each diversion channel 130, and foreign matter is intercepted through the fluid lifting section 102 and the intercepting portion 140. Based on the configuration of the stacked diversion channels 130, in each diversion channel 130, there is a first opening 131 at the front end to form a part of the input part 110, and a second opening 132 at the rear end to form a part of the output part 120. In each diversion channel 130, the first opening 131 is configured to be lower than the second opening 132, so that the fluid lifting section 102 is defined on the flow channel between the first opening 131 and the second opening 132, and the corresponding intercepting portion 140 is configured at a position adjacent to the second opening 132 and located at the lower side of the second opening 132.

[0021] In the front intercepting device 100, a plurality of spacers 106 stacked at intervals can be supported by a plurality of ribs 104 to form a spaced configuration. These ribs 104 include but are not limited to the two end edges of the spacers 106, which can further form a frame 104' of the front intercepting device 100. Each spacer 106 is connected by the ribs 104 to construct the structure of the front intercepting device 100 and define the size of each diversion channel 130. For example, the greater the distance between two adjacent spacers 106, the larger the size of the corresponding diversion channel 130. Similarly, based on the stacking configuration, the front section of these spacers 106 defines the input part 110, and the rear section of these spacers defines the output part 120, and each diversion channel 130 can be defined between two adjacent spacers.

[0022] Regarding the intercepting portion 140 corresponding to each branch flow channel 130, in the first embodiment, the intercepting portion 140 is configured based on the reversed portion 1061 extending upward and then protruding forward (toward the input portion 110) configured on the rear section of the spacer 106. In addition, the front section of the spacer 106 has a portion 1062 extending vertically downward, so as to be configured together with the adjacent spacer 106 as a part of the input portion 110.

[0023] Among them, the top-layer spacer 106' is configured to have no inflected portion 1061, and may further have a first extension portion 1063. Correspondingly, the bottom-layer spacer 106" is configured to have no portion 1062 extending vertically downward, and may further have a second extension portion 1064. In some applications, the first extension portion 1063 and the second extension portion 1064 can be used to set up the shell of the rear-end electronic device, in addition to the connecting components such as snaps or pressing required for assembly, and can be used in conjunction with the frame 104' to provide a configuration position for the filter.

[0024] Further, see Figure 3The position of the upper surface of the inflected portion 1061 can be configured to be equivalent to (the difference is very small or can be called substantially equal to) the lower edge of the portion 1062 extending vertically downward. In addition to forming a good fluid lifting section 102, such a configuration is also beneficial to the structural construction cost of the one-piece front interception device 100.

[0025] Next, please refer to Figure 5 , Figure 6 and Figure 7 , Figure 5 is a three-dimensional cross-sectional schematic diagram of a front interception device in a second implementation manner according to some embodiments, Figure 6 for Figure 5 A cross-sectional schematic diagram of an implementation method, Figure 7 for Figure 5 A three-dimensional schematic diagram of a rear side view under an implementation method.

[0026] The pre-intercepting device 200 in the second embodiment also has stacked diversion channels 230, so that the fluid flowing into the pre-intercepting device 200 is diverted to each diversion channel 230, and foreign matter is intercepted through the fluid lifting section 202 and the intercepting portion 240. Based on the configuration of the stacked diversion channels 230, in each diversion channel 230, there is a first opening 231 at the front end to form a part of the input part 210, and a second opening 232 at the rear end to form a part of the output part 220. In each diversion channel 230, the first opening 231 is configured to be lower than the second opening 232, so that the fluid lifting section 202 is defined on the channel between the first opening 231 and the second opening 232, and the corresponding intercepting portion 240 is configured at a position adjacent to the second opening 232 and located at the lower side of the second opening 232.

[0027] In the front intercepting device 200, a plurality of spacers 206 stacked at intervals can be supported by a plurality of ribs 204 to form a spaced configuration. These ribs 204 include but are not limited to the two end edges of the spacers 206, and can further form a frame 204' of the front intercepting device 200 by increasing the thickness. Each spacer 206 is connected by the ribs 204 to construct the structure of the front intercepting device 200 and define the size of each diversion channel 230. For example, the farther the distance between two adjacent spacers 206, the larger the size of the corresponding diversion channel 230. Similarly, based on the stacking configuration, the front section of these spacers 206 defines the input section 210, and the rear section of these spacers defines the output section 220, and each diversion channel 230 can be defined between two adjacent spacers.

[0028] Regarding the interception portion 240 corresponding to each flow branch channel 230, in the second embodiment, the interception portion 240 is configured based on the reverse folded portion 2061 extending upward and then protruding forward (toward the side of the input portion 210) configured on the rear section of the spacer 206. In addition, the front section of the spacer 206 has an eaves portion 2062 extending downward and outwardly obliquely, so as to be configured together with the adjacent spacer 206 as a part of the input portion 110. In some other applications, the upper surface of the eaves portion 2062 can be further configured with a decorative pattern structure or an anti-slip layer to provide the ability to capture foreign matter in the fluid, so that part of the foreign matter is captured on the upper surface of the inclined portion 2062.

[0029] Among them, the top-layer spacer 206' is configured to have no inflected portion 2061, and may further have a first extension portion 2063. Correspondingly, the bottom-layer spacer 206" is configured to have no eaves portion 2062 extending downward and outward, and may further have a second extension portion 2064. In some applications, the first extension portion 2063 and the second extension portion 2064 can be used to set up the shell of the rear-end electronic device, in addition to the connecting components such as snaps or pressing required for assembly, and can be used in conjunction with the frame 204' to provide a configuration position for the filter.

[0030] Further, see Figure 6 The position of the upper surface of the inflected portion 2061 can be configured to be equivalent to (the difference is very small or can be called substantially equal to) the lower edge (the lowest position) of the eaves portion 2062. In addition to forming a good fluid lifting section 202, such a configuration is also beneficial to the structural construction cost of the one-piece front interception device 200.

[0031] Please also refer to Figure 8 and Fig. 9 , Figure 8 is a partial cross-sectional schematic diagram of an electronic device equipped with a front interception device of the first embodiment according to some embodiments, Fig. 9 It is a partial cross-sectional schematic diagram of an electronic device equipped with a front interception device of the second embodiment according to some embodiments.

[0032] Electronic devices need to introduce external fluids (e.g., air) for heat dissipation or supply to internal systems that require such fluids based on heat dissipation needs or other requirements. Through the configuration of the front interception device, the input external fluid can be subjected to a first-stage preliminary filtration to remove some foreign matter. The fluid output from the front interception device then flows through the filter and undergoes a second-stage filtration through the filter to provide fluids of the required cleanliness level to the interior of the electronic device. With the assistance of the front interception device, foreign matter with special physical properties (e.g., heavier weight or larger volume, etc.) will be captured by the front interception device first and will not easily enter the filter at the rear end. The life of the higher-cost filter can be increased, and the replacement frequency of the filter can be effectively reduced.

[0033] like Figure 8 and Fig. 9 The pre-intercepting device 100, 200 is detachably arranged (for example, using a detachable connecting member of a buckle, pressing or other connecting method) on the fluid input side of the electronic device 400. A filter 300 is arranged at the connection between the pre-intercepting device 100, 200 and the electronic device 400, so that the pre-intercepting device performs a first-stage preliminary filtration, and then the filter 300 provides a second-stage filtration. Based on the structural configuration of the pre-intercepting device 100, 200, the difference from the filter 300 is that foreign matter will not be stuck in the fine through-hole structure (for example, the fine through-holes woven by the filter fabric), and therefore, foreign matter captured in the structure of the pre-intercepting device 100, 200 can be easily cleaned by disassembling the pre-intercepting device 100, 200 (for example, by the impact of high-speed fluid of an air spray gun), so that the pre-intercepting device 100, 200 can be quickly cleaned and reused.

[0034] In some application modes, the front interception device 100 , 200 can provide a configuration space for the filter 300 through the first extension portion 1063 , 2063 and the second extension portion 1064 , 2064 .

[0035] The combination of the front interception device and the filter is configured as a filtering system for electronic equipment. In such a combined filtering system, the filter can give full play to its function of filtering smaller foreign matter, and is not easily consumed by larger foreign matter, so that the filter can give full play to its filtering function and effectively extend the service life of the filter. The detachable front interception device 100, 200 can be easily disassembled to perform cleaning work, which is especially important in some more severe use environments (for example: large amount of dust, electronic equipment is placed near the ground and is easy to inhale too many foreign matter, etc.). The filtering system of electronic equipment with a front interception device can provide a better solution with lower cost.

[0036] For example, it has been verified through experiments that an electronic device without a pre-interceptor and using only a filter to build a filtration system, under extreme full-speed air volume usage (the flow rate formed by the suction into the electronic device is about 3.5m / s), the filter will no longer be able to provide filtering work in about a week (or the air permeability of the filter can be said to be too low). Under the same environment and the same specification of the filter, an electronic device with the pre-interceptor of the first method is used and a filter is used to build a filtration system. Under extreme full-speed air volume usage (the flow rate formed by the suction into the electronic device is about 3.5m / s), the time that the filter can no longer provide filtering work is extended to two weeks. In addition, under the same environment and the same specification of the filter, an electronic device with the pre-interceptor is used and a filter is used to build a filtration system. Under normal air volume usage (the flow rate formed by the suction into the electronic device is about 1.75m / s), the time that the filter can no longer provide filtering work is extended to 3 months.

[0037] In this way, the pre-interception device plays a good pre-filtration effect on the overall filtration system, and the importance of the pre-interception device can be highlighted in some special use environments. In addition, this also makes it possible to significantly extend the life of the filter under certain wind speed adjustments (for example, the air intake of electronic equipment uses a general air volume setting), and foreign matter that is not the focus of the filter can be captured in the pre-interception device first, and the pre-interception device plays an excellent interception effect.

[0038] In summary, in some embodiments of the present invention, the pre-interceptor device and the filtering system using the pre-interceptor device provide a better foreign matter filtering mechanism, and the physical properties of foreign matter are used to design the interceptor device, thereby achieving a filtering effect on the fluid passing through. Furthermore, when the pre-interceptor device is combined with a filter screen to form a filtering system, the burden of the filter screen can be further reduced, the service life of the filter screen can be extended, and the construction cost of the overall filtering system and the cost of replacing consumables can be reduced.

[0039] The present invention discloses preferred embodiments above, but those skilled in the art should understand that the embodiments herein are only used to describe the present invention and should not be interpreted as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the embodiments should be understood to be included in the scope of the present invention.
