Description
本發明是有關於一種散熱裝置,特別是有關於可除塵式的風扇散熱裝置。The present invention relates to a heat sink, and more particularly to a dust-removable fan heat sink.
一般來說計算裝置,如筆記型電腦(Notebook)、個人電腦等,正常運轉時,為發散計算元件或其他元件所產生的熱,需透過設置散熱模組,像是散熱鰭片、風扇模組、導熱管等,藉此避免熱累積於計算裝置中,使得計算裝置內的溫度升高,而影響計算裝置的運作,嚴重者,甚至可能讓計算裝置內的元件毀損或停止運轉。然而,隨著日積月累的使用,正常使用環境中的灰塵等,會容易堆積於計算裝置的散熱模組,例如散熱鰭片間的空間或風扇出氣口等,使得散熱模組較不易與冷空氣交換、發散熱能。同樣地,堆積於散熱模組的灰塵也會影響冷空氣進入散熱模組的路徑。甚或,於部分的情況中,灰塵會堵塞散熱鰭片間的空間或出氣口,而使散熱模組無法與外界的冷空氣作快速的交換,降低散熱模組的散熱效率,也影響計算裝置內的溫度,以及可能進一步地影響到計算裝置的正常運轉。由此可見,上述現有的架構,顯然仍存在不便與缺陷,而有待加以進一步改進。爲了解决上述問題,相關領域莫不費盡心思來謀求解决之道,但長久以來一直未見適用的方式被發展完成。因此,如何能有效解决上述問題,實屬當前重要研發課題之一,亦成爲當前相關領域亟需改進的目標。In general, computing devices, such as notebooks, personal computers, etc., in the normal operation, the heat generated by the divergent computing components or other components, through the provision of thermal modules, such as cooling fins, fan modules A heat pipe or the like, thereby preventing heat from accumulating in the computing device, causing the temperature in the computing device to rise, thereby affecting the operation of the computing device. In severe cases, the components in the computing device may even be damaged or stopped. However, with the accumulation of use, the dust in the normal use environment, etc., can easily accumulate in the heat dissipation module of the computing device, such as the space between the heat dissipation fins or the fan air outlet, so that the heat dissipation module is less likely to be exchanged with cold air. And heat dissipation. Similarly, dust deposited on the heat sink module can also affect the path of cold air entering the heat sink module. Or, in some cases, dust may block the space between the fins or the air outlet, so that the heat dissipation module cannot be quickly exchanged with the cold air outside, reducing the heat dissipation efficiency of the heat dissipation module, and also affecting the calculation device. The temperature, and possibly further affects the normal operation of the computing device. It can be seen that the above existing architecture obviously has inconveniences and defects, and needs to be further improved. In order to solve the above problems, the relevant fields have not exhausted their efforts to seek solutions, but the methods that have not been applied for a long time have been developed. Therefore, how to effectively solve the above problems is one of the current important research and development topics, and it has become an urgent target for improvement in related fields.
本發明之一技術態樣是有關於一種包含風扇模組的散熱裝置,其利用設置可切換式的導流板於風扇模組的殼體中,而使得風扇的流場隨導流板的位置而變化。當風扇模組的封閉件開啟出氣口,且導流板相對於殼體轉動而阻擋於集壓區與第二部分之間時,風扇模組處於正常狀態,風扇件將冷空氣自進氣口帶往出氣口。當封閉件封閉出氣口,且導流板相對於殼體轉動而阻擋於集壓區與第一部分之間時,散熱裝置處於除塵模式,風扇件將加壓的空氣自進氣口的第一部分帶往進氣口的第二部分,以帶動黏滯於風扇模組進氣口外或散熱鰭片間的灰塵,並透過進氣口的第二部分排除灰塵。如此一來,可降低或避免散熱裝置因灰塵堆積影響到空氣流通進入風扇模組的情況,使散熱裝置的工作效率提高。One aspect of the present invention relates to a heat dissipating device including a fan module, which utilizes a switchable baffle plate in a housing of a fan module, such that a flow field of the fan follows the position of the baffle And change.

第1圖繪示依據本發明多個實施方式之散熱裝置100處於第一模式時的立體圖,其中第一模式可為正常運轉模式。第2圖依據第1圖繪示本發明多個實施方式之散熱裝置100處於第一模式時的上視透視圖。如第1圖以及第2圖所示,散熱裝置100包含風扇模組110、散熱鰭片140以及導流板150(參見第2圖)。風扇模組110包含殼體120、風扇件130以及封閉件190(參見第3圖或第4圖)。殼體120具有殼內空間122、出氣口124以及進氣口,並包含側牆128。在多個實施方式中,殼體120可包含底板127,與側牆128共同定義殼內空間122。出氣口124位於底板127,且當散熱裝置100為正常運轉模式時,出氣口124可開啟連通殼內空間122與外界,以排除熱空氣。進氣口具有第一部分126a以及第二部分126b。側牆128具有舌部129。風扇件130樞設於殼內空間122中,並沿著單一旋轉方向相對殼體120旋轉,其中側牆128與風扇件130之間由舌部129沿著旋轉方向至進氣口定義集壓區132。封閉件190設置於出氣口124,配置以可選擇性地開啟或封閉出氣口124。散熱鰭片140設置於進氣口的第一部分126a。導流板150樞接殼體120於進氣口的第一部分126a以及第二部分126b之間,並延伸進入殼內空間122。當散熱裝置100處於第一模式或正常運轉模式時,封閉件190開啟出氣口124,且導流板150相對於殼體120轉動而阻擋於集壓區132與進氣口的第二部分126b之間,以將集壓區132與進氣口的第二部分126b隔開,讓氣流自進氣口的第一部分126a進入殼內空間122後,經風扇件130推送、加壓至集壓區132而自出氣口124離開風扇模組110。當散熱裝置100處於正常運轉模式時,導流板150可隔絕殼內空間122與進氣口的第二部分126b相連通,使得氣流僅得以自出氣口124離開風扇模組110。FIG. 1 is a perspective view of the heat dissipation device 100 according to various embodiments of the present invention in a first mode, wherein the first mode may be a normal operation mode. FIG. 2 is a top perspective view of the heat sink 100 according to various embodiments of the present invention in a first mode, according to FIG. As shown in FIGS. 1 and 2, the heat sink 100 includes a fan module 110, heat sink fins 140, and a deflector 150 (see FIG. 2). The fan module 110 includes a housing 120, a fan member 130, and a closure member 190 (see FIG. 3 or FIG. 4). The housing 120 has a housing inner space 122, an air outlet 124, and an air inlet, and includes a side wall 128. In various embodiments, the housing 120 can include a bottom plate 127 that defines a housing interior space 122 in conjunction with the side walls 128. The air outlet 124 is located on the bottom plate 127, and when the heat sink 100 is in the normal operation mode, the air outlet 124 can open the communication inner space 122 and the outside to exclude hot air. The air inlet has a first portion 126a and a second portion 126b. The side wall 128 has a tongue 129. The fan member 130 is pivoted in the housing inner space 122 and rotates relative to the housing 120 along a single rotation direction. The gap between the side wall 128 and the fan member 130 is defined by the tongue 129 along the rotation direction to the air inlet. 132. The closure member 190 is disposed at the air outlet 124 and is configured to selectively open or close the air outlet 124. The heat dissipation fins 140 are disposed at the first portion 126a of the air inlet. The deflector 150 pivotally connects the housing 120 between the first portion 126a and the second portion 126b of the air inlet and extends into the inner space 122 of the housing. When the heat sink 100 is in the first mode or the normal operation mode, the closing member 190 opens the air outlet 124, and the deflector 150 rotates relative to the housing 120 to block the pressure collecting portion 132 and the second portion 126b of the air inlet. During the interval, the pressure collecting zone 132 is separated from the second portion 126b of the air inlet, and the airflow enters the inner space 122 from the first portion 126a of the air inlet, and is pushed and pressurized to the pressure collecting area 132 by the fan member 130. The air outlet 124 exits the fan module 110. When the heat sink 100 is in the normal operation mode, the deflector 150 can insulate the inner space 122 of the housing from the second portion 126b of the air inlet so that the airflow can only exit the fan module 110 from the air outlet 124.
第3圖繪示依據本發明多個實施方式之散熱裝置100處於第二模式時的立體圖,其中第二模式可為除塵模式。第4圖依據第3圖繪示本發明多個實施方式之散熱裝置100處於第二模式時的上視透視圖,其中散熱裝置100的風扇件130因受封閉件190遮蔽而繪示為虛線。如第3圖以及第4圖所示,當散熱裝置100處於第二模式或除塵模式時,封閉件190可封閉出氣口124,且導流板150相對於殼體120轉動而阻擋於集壓區132與進氣口的第一部分126a之間,以將自進氣口的第一部分126a受風扇件130產生之負壓所吸引之氣流,自進氣口的第一部分126a進入殼內空間122後,經風扇件130推送、加壓至集壓區132而自與集壓區132連通的進氣口之第二部分126b離開風扇模組110。FIG. 3 is a perspective view of the heat sink 100 according to various embodiments of the present invention in a second mode, wherein the second mode may be a dust removal mode. 4 is a top perspective view of the heat sink 100 of the embodiment of the present invention in a second mode, wherein the fan member 130 of the heat sink 100 is shown as a broken line by the cover member 190. As shown in FIG. 3 and FIG. 4, when the heat sink 100 is in the second mode or the dust removal mode, the closing member 190 can close the air outlet 124, and the deflector 150 rotates relative to the housing 120 to block the pressure collecting area. Between the first portion 126a of the air inlet and the first portion 126a of the air inlet, the first portion 126a of the air inlet is attracted by the negative pressure generated by the fan member 130, and the first portion 126a of the air inlet enters the inner space 122 of the housing. The second portion 126b of the air inlet that is pushed and pressurized by the fan member 130 to the pressure collecting portion 132 and communicates with the pressure collecting portion 132 leaves the fan module 110.
由於導流板150可切換式地裝設於風扇模組110的殼體120中,可選擇性地於正常運轉模式中抵靠側牆128而阻擋於集壓區132與進氣口的第二部分126b之間,或於除塵模式中遠離側牆128而阻擋於集壓區132與進氣口的第一部分126a之間,讓經風扇件130與殼體120共同加壓後的氣流受導流板150與封閉件190共同作用而自出氣口124離開或自進氣口的第二部分126b離開,且無需變更風扇件130的旋轉方向。當封閉件190封閉出氣口124,且導流板150阻擋於集壓區132與進氣口的第一部分126a之間時,風扇件130可將加壓後的空氣自進氣口的第一部分126a帶往進氣口的第二部分126b,藉由加壓的氣流帶動黏滯於風扇模組110進氣口外或散熱鰭片140間的灰塵進入殼內空間122,並隨著風扇件130推送、加壓的氣流自進氣口的第二部分126b離開,以達致排除灰塵的功能。如此一來,散熱裝置100可於不改變風扇件130旋轉方向的情況下,排除堆積於散熱裝置100之散熱鰭片140與風扇模組110的灰塵,藉此,可降低或避免散熱裝置100因灰塵堆積影響到空氣流通進入風扇模組110的情況,使散熱裝置100的工作效率以及熱交換效率提高。Since the baffle 150 is switchably mounted in the housing 120 of the fan module 110, it can selectively block the side wall 128 in the normal operation mode and block the second portion of the pressure collecting area 132 and the air inlet. Between the portions 126b, or away from the side wall 128 in the dust removal mode, between the pressure collecting portion 132 and the first portion 126a of the air inlet, the airflow after being co-pressurized by the fan member 130 and the housing 120 is diverted. The plate 150 cooperates with the closure member 190 to exit from the air outlet 124 or exit from the second portion 126b of the air inlet without changing the direction of rotation of the fan member 130. When the closure member 190 encloses the air outlet 124 and the deflector 150 blocks between the pressure collecting region 132 and the first portion 126a of the air inlet, the fan member 130 can pressurize the air from the first portion 126a of the air inlet. The second portion 126b of the air inlet is driven by the pressurized airflow to attract dust that is stuck outside the air inlet of the fan module 110 or between the heat dissipation fins 140 into the housing space 122, and is pushed along with the fan member 130. The pressurized air flow exits from the second portion 126b of the air inlet to achieve the function of removing dust. In this way, the heat dissipation device 100 can remove the dust accumulated on the heat dissipation fins 140 and the fan module 110 of the heat dissipation device 100 without changing the rotation direction of the fan member 130, thereby reducing or avoiding the heat dissipation device 100. The dust accumulation affects the flow of air into the fan module 110, and the work efficiency and heat exchange efficiency of the heat sink 100 are improved.
參照第2圖,在多個實施方式中,進氣口的第一部分126a的截面積大於進氣口的第二部分126b的截面積。換句話說,在多個實施方式中,進氣口的第一部分126a具有寬度d1以及進氣口的第二部分126b具有寬度d2,且進氣口的第一部分126a以及進氣口的第二部分126b共同具有高度S,進氣口的第一部分126a之寬度d1大於進氣口的第二部分126b之寬度d2。如此一來,可讓第4圖中,位於進氣口的第一部分126a之氣流的速度小於進氣口的第二部分126b的速度,以製造氣流流經進氣口的第一部分126a與進氣口的第二部分126b時的壓力差,讓氣流可順暢地自進氣口的第一部分126a經風扇件130至進氣口的第二部分126b離開,且可進一步地減少或避免灰塵自進氣口的第一部分126a進入殼內空間122後,因壓力差過小,而留滯於殼內空間122中,更影響散熱裝置100的運作。Referring to Figure 2, in various embodiments, the cross-sectional area of the first portion 126a of the air inlet is greater than the cross-sectional area of the second portion 126b of the air inlet. In other words, in various embodiments, the first portion 126a of the intake port has a width d1 and the second portion 126b of the intake port has a width d2, and the first portion 126a of the intake port and the second portion of the intake port The 126b collectively has a height S, and the width d1 of the first portion 126a of the air inlet is greater than the width d2 of the second portion 126b of the air inlet. As such, in FIG. 4, the velocity of the airflow at the first portion 126a of the air inlet is less than the velocity of the second portion 126b of the air inlet to create a first portion 126a and airflow through which the airflow flows. The pressure difference at the second portion 126b of the port allows the airflow to smoothly exit from the first portion 126a of the air inlet through the fan member 130 to the second portion 126b of the air inlet, and further reduce or avoid dust from the air intake After the first portion 126a of the mouth enters the inner space 122 of the casing, the pressure difference is too small, and stays in the inner space 122 of the casing, which further affects the operation of the heat sink 100.
參照第4圖,在多個實施方式中,當散熱裝置100處於第二模式或除塵模式時,導流板150遠離進氣口的一端與側牆128靠近進氣口的第一部分126a的一側之間的最短距離d3大於導流板150遠離進氣口的一端與側牆128靠近進氣口的第二部分126b的一側之間的最短距離d4。亦即,當散熱裝置100於除塵模式時,以導流板150阻擋而將殼內空間122靠近進風口的一側分隔成兩部分,其中靠近進風口的第一部分126a之部分的截面積大於靠近進風口的第二部分126b之部分的截面積,以讓進氣口的第一部分126a之氣流的速度小於進氣口的第二部分126b的速度,使得氣流流經進氣口的第一部分126a與進氣口的第二部分126b時可製造壓力差,讓氣流可更順暢地自進氣口的第一部分126a經風扇件130至進氣口的第二部分126b離開。Referring to FIG. 4, in various embodiments, when the heat sink 100 is in the second mode or the dust removal mode, the end of the deflector 150 away from the air inlet and the side wall 128 are adjacent to the side of the first portion 126a of the air inlet. The shortest distance d3 between is greater than the shortest distance d4 between the end of the baffle 150 away from the air inlet and the side of the side wall 128 adjacent the second portion 126b of the air inlet. That is, when the heat dissipating device 100 is in the dust removing mode, the side of the inner space 122 close to the air inlet is blocked by the deflector 150, and the cross-sectional area of the portion close to the first portion 126a of the air inlet is larger than the closer. The cross-sectional area of the portion of the second portion 126b of the air inlet is such that the velocity of the airflow of the first portion 126a of the air inlet is less than the velocity of the second portion 126b of the air inlet such that the airflow flows through the first portion 126a of the air inlet The second portion 126b of the air inlet can create a pressure differential that allows the airflow to more smoothly exit from the first portion 126a of the air inlet through the fan member 130 to the second portion 126b of the air inlet.
同樣地,參照第4圖,在多個實施方式中,當散熱裝置100處於第二模式或除塵模式時,進氣口的第一部分126a的截面積大於導流板150遠離進氣口的一端與舌部129之間的截面積。換句話說,在多個實施方式中,散熱裝置100處於除塵模式時,進氣口的第一部分126a具有寬度d5以及導流板150遠離進氣口的一端與舌部129之間的寬度d3,且進氣口的第一部分126a與殼內空間122共同具有高度S,進氣口的第一部分126a之寬度d5大於導流板150遠離進氣口的一端與舌部129之間的寬度d3。如此一來,可讓第4圖中,受風扇件130所製造的負壓而吸引之氣流自進氣口的第一部分126a進入殼內空間122後的速度小於流經導流板150遠離進氣口的一端與舌部129之間的速度,可更大程度地加壓進入風扇件130前的氣流速度,讓氣流進入風扇件130後可更順暢地至進氣口的第二部分126b離開。Similarly, referring to FIG. 4, in various embodiments, when the heat sink 100 is in the second mode or the dust removal mode, the cross-sectional area of the first portion 126a of the air inlet is greater than the end of the deflector 150 away from the air inlet. The cross-sectional area between the tongues 129. In other words, in various embodiments, when the heat sink 100 is in the dust removal mode, the first portion 126a of the air inlet has a width d5 and a width d3 between the end of the deflector 150 away from the air inlet and the tongue 129, And the first portion 126a of the air inlet has a height S together with the inner space 122, and the width d5 of the first portion 126a of the air inlet is greater than the width d3 between the end of the deflector 150 away from the air inlet and the tongue 129. In this way, in FIG. 4, the airflow attracted by the negative pressure generated by the fan member 130 enters the inner space 122 from the first portion 126a of the air inlet port, and the speed is smaller than that of the air flow through the deflector 150. The velocity between one end of the mouth and the tongue 129 can pressurize the airflow velocity in front of the fan member 130 to a greater extent, allowing the airflow to enter the fan member 130 to more smoothly exit the second portion 126b of the air inlet.
值得注意的是,此處所述之進氣口的第一部分126a之截面積與進氣口的第二部分126b之截面積、導流板150阻擋而將殼內空間122靠近進風口的一側分隔成兩部分,其中靠近進風口的第一部分126a之部分的截面積與靠近進風口的第二部分126b之部分的截面積,或進氣口的第一部分126a之截面積與導流板150遠離進氣口的一端與舌部129之間之截面積等,僅為示例,並非用以限制本發明。應瞭解到,本領域具有通常知識者,可視實際需要,在不脫離本揭露的精神和範圍下,做適度的修改或替代,只要當散熱裝置100處於除塵模式時,氣流可攜帶灰塵自進氣口的第一部分126a受風扇件130所產生之壓力差吸引,而進入風扇件130加壓,再自進氣口的第二部分126b離開即可。It should be noted that the cross-sectional area of the first portion 126a of the air inlet described herein and the cross-sectional area of the second portion 126b of the air inlet, and the side of the air deflector 150 that blocks the inner space 122 of the housing near the air inlet. Divided into two parts, wherein the cross-sectional area of the portion of the first portion 126a adjacent to the air inlet is close to the cross-sectional area of the portion of the second portion 126b adjacent to the air inlet, or the cross-sectional area of the first portion 126a of the air inlet is away from the deflector 150 The cross-sectional area between the one end of the air inlet and the tongue 129 is merely an example and is not intended to limit the present invention. It should be understood that those skilled in the art can make appropriate modifications or substitutions without departing from the spirit and scope of the disclosure, as long as the heat sink 100 is in the dust removal mode, the airflow can carry dust from the air intake. The first portion 126a of the port is attracted by the pressure differential created by the fan member 130, and is forced into the fan member 130 and then exits from the second portion 126b of the air inlet.
參照第3圖,在多個實施方式中,封閉件190可為快門式開關。風扇模組110可更包含控制按鈕160,配置以開啟或關閉快門式開關。應瞭解到,此處所述之封閉件190的形式僅為示例,並非用以限制本發明,本領域具有通常知識者,可視實際需要,在不脫離本揭露的精神和範圍下,做適度的修改或替代,只要控制按鈕160可選擇性地控制封閉件190開啟或關閉出氣口124與殼內空間122連通即可。Referring to Figure 3, in various embodiments, the closure 190 can be a shutter switch. The fan module 110 can further include a control button 160 configured to turn the shutter switch on or off. It should be understood that the form of the closure member 190 described herein is only an example, and is not intended to limit the present invention. Those skilled in the art can make appropriate measures without departing from the spirit and scope of the disclosure. Modifications or substitutions may be made as long as the control button 160 selectively controls the closure member 190 to open or close the air outlet 124 in communication with the housing interior space 122.
在多個實施方式中,導流板150遠離進氣口的一端連結快門式開關,其中當快門式開關封閉時,快門式開關帶動導流板150的遠離進氣口的一端遠離側牆128。在多個實施方式中,導流板150可透過連動桿連結封閉件190,以與封閉件190連動。在多個實施方式中,導流板150可與封閉件190分開動作。在多個實施方式中,導流板150可包含活門與連動桿(圖未繪示)。In various embodiments, the end of the baffle 150 away from the air inlet is coupled to the shutter switch, wherein when the shutter switch is closed, the shutter switch drives the end of the baffle 150 away from the air inlet away from the side wall 128. In various embodiments, the baffle 150 can be coupled to the closure 190 through the linkage rod to interlock with the closure 190.

第5圖繪示依據本發明另外的多個實施方式之散熱裝置200處於第一模式時的上視透視圖,其中第一模式可為正常運轉模式。第6圖繪示依據本發明另外的多個實施方式之散熱裝置200處於第二模式時的上視透視圖,其中第二模式可為除塵模式。如第5圖以及第6圖所示,在多個實施方式中,導流板150可包含第一磁性件170。在多個實施方式中,第一磁性件170設置於導流板150靠近進氣口的第二部分126b的一端。散熱裝置200可更包含第二磁性件180。第二磁性件180配置以可選擇性地吸引第一磁性件170,使導流板150遠離進氣口的一端扺靠殼體120,或排斥第一磁性件170,使導流板150遠離進氣口的一端遠離殼體120。FIG. 5 is a top perspective view of the heat sink 200 according to further embodiments of the present invention in a first mode, wherein the first mode may be a normal operation mode. 6 is a top perspective view of the heat sink 200 according to further embodiments of the present invention in a second mode, wherein the second mode may be a dust removal mode. As shown in FIGS. 5 and 6, in various embodiments, the baffle 150 can include a first magnetic member 170. In various embodiments, the first magnetic member 170 is disposed at one end of the deflector 150 adjacent the second portion 126b of the air inlet. The heat sink 200 may further include a second magnetic member 180. The second magnetic member 180 is configured to selectively attract the first magnetic member 170 such that one end of the deflector 150 away from the air inlet is against the housing 120 or repels the first magnetic member 170 to keep the deflector 150 away from the inlet. One end of the port is remote from the housing 120.
在多個實施方式中,第二磁性件180包含核心184、線圈182以及電源供應(圖未繪示)。線圈182纏繞核心184。在多個實施方式中,線圈182與核心184間互相絕緣。電源供應電性連接線圈182。在多個實施方式中,電源供應可為交流供應源或可切換式地直流供應源。如第6圖所示,當電源供應發出第一電流時,第二磁性件180排斥第一磁性件170,使導流板150遠離進氣口的一端遠離側牆128而阻擋於集壓區132與進氣口的第一部分126a之間。舉例來說,當第一磁性件170朝向側牆128的一側為N極,而電源供應發出第一電流讓線圈182與核心184朝向第一磁性件170的一側感應成N極而與第一磁性件170互斥,讓第一磁性件170轉動而帶動導流板150遠離進氣口的一端遠離側牆128。但不限於此,本領域具有通常知識者,可視實際需要,在不脫離本揭露的精神和範圍下,做適度的修改或替代,只要在電源供應發出第一電流讓線圈182與核心184感應產生磁極的情況下,能夠排斥第一磁性件170轉動導流板150遠離側牆128即可。In various embodiments, the second magnetic member 180 includes a core 184, a coil 182, and a power supply (not shown). The coil 182 is wound around the core 184. In various embodiments, the coil 182 and the core 184 are insulated from each other. The power supply is electrically connected to the coil 182. In various embodiments, the power supply can be an alternating current supply or a switchable direct current supply. As shown in FIG. 6, when the power supply supplies the first current, the second magnetic member 180 repels the first magnetic member 170, so that one end of the deflector 150 away from the air inlet is away from the side wall 128 and blocks from the pressure collecting region 132. Between the first portion 126a of the air inlet. For example, when the first magnetic member 170 faces the side wall 128, the anode is N pole, and the power supply sends a first current to cause the coil 182 and the core 184 to be inductive to the N pole on the side of the first magnetic member 170. A magnetic member 170 is mutually exclusive, and the first magnetic member 170 is rotated to drive the end of the deflector 150 away from the air inlet away from the side wall 128. However, the present invention is not limited thereto, and those skilled in the art can make appropriate modifications or substitutions without departing from the spirit and scope of the present disclosure, as long as the first current is supplied to the power supply to cause the coil 182 and the core 184 to be induced. In the case of the magnetic pole, the first magnetic member 170 can be repelled to rotate the deflector 150 away from the side wall 128.
如第5圖所示,在多個實施方式中,當電源供應發出第二電流時,其中第一電流的方向與第二電流的方向相反,第二磁性件180吸引第一磁性件170,使導流板150遠離進氣口的一端扺靠側牆128而阻擋於集壓區132與進氣口的第二部分126b之間。舉例來說,當第一磁性件170朝向側牆128的一側為N極,而電源供應發出方向與第一電流方向相反的第二電流讓線圈182與核心184朝向第一磁性件170的一側感應成S極而與第一磁性件170相吸,讓第一磁性件170轉動而帶動導流板150遠離進氣口的一端抵靠側牆128。但不限於此,本領域具有通常知識者,可視實際需要,在不脫離本揭露的精神和範圍下,做適度的修改或替代,只要在電源供應發出第二電流讓線圈182與核心184感應產生磁極的情況下,能夠吸引第一磁性件170轉動導流板150朝向側牆128移動即可。As shown in FIG. 5, in various embodiments, when the power supply supplies a second current, wherein the direction of the first current is opposite to the direction of the second current, the second magnetic member 180 attracts the first magnetic member 170, so that One end of the deflector 150 away from the intake port abuts against the side wall 128 and blocks between the pressure collecting zone 132 and the second portion 126b of the air inlet. For example, when the first magnetic member 170 faces the side wall 128, the side is N pole, and the power supply sends a second current whose direction is opposite to the first current direction, so that the coil 182 and the core 184 face the first magnetic member 170. The side is attracted to the S pole and is attracted to the first magnetic member 170, and the first magnetic member 170 is rotated to drive the end of the deflector 150 away from the air inlet against the side wall 128. However, the present invention is not limited thereto, and those skilled in the art can make appropriate modifications or substitutions without departing from the spirit and scope of the present disclosure, as long as the second current is supplied to the power supply to cause the coil 182 and the core 184 to be induced. In the case of the magnetic pole, the first magnetic member 170 can be attracted to move the deflector 150 toward the side wall 128.
在多個實施方式中,當導流板150遠離進氣口的一端扺靠側牆128時,電源供應可停止第二電流,而讓第一磁性件170與核心184間互相磁性吸引。舉例來說,核心184可為具暫時性鐵磁性的物質,受線圈182上不同的電流感應成不同的磁極排列,當第一磁性件170靠近核心184後,即便切斷電源供應,由於核心184已受第一磁性件170暫時磁化而與第一磁性件170相吸,故仍可維持互相吸引的狀態,直到電源供應提供第一電流為止。In various embodiments, when the end of the baffle 150 away from the air inlet is against the side wall 128, the power supply can stop the second current and magnetically attract the first magnetic member 170 and the core 184. For example, the core 184 can be a temporary ferromagnetic material that is induced into different pole arrangements by different currents on the coil 182. When the first magnetic member 170 is close to the core 184, even if the power supply is cut off, due to the core 184 The first magnetic member 170 has been temporarily magnetized to attract the first magnetic member 170, so that the mutually attracted state can be maintained until the power supply supplies the first current.
