Abstract
Description
本發明與發電機有關，特別是指一種具有散熱機制的發電機。 The present invention is related to generators, and particularly refers to a generator with a heat dissipation mechanism.
關於發電機，包括一殼體、樞接於殼體的一轉軸、以及皆設置於殼體內的一定子和一轉子，藉由轉子相對於定子旋轉而發電。 The generator includes a casing, a shaft pivotally connected to the casing, a stator and a rotor both disposed in the casing, and the rotor rotates relative to the stator to generate electricity.
然而發電機在運轉發電時，必會產生熱，現有發電機卻只開設用來被動散熱的透氣孔，熱氣只能從透氣孔緩慢流出，導致發電機常有過熱停機的情形，嚴重者甚至還可能會燒毀發電機的內部零組件。 However, when the generator is running to generate electricity, it will generate heat. The existing generators only have ventilation holes for passive heat dissipation, and the hot air can only flow out slowly from the ventilation holes, which often causes the generator to overheat and shut down. The generator's internal components may be burned.
本發明的目的在於提供一種具有散熱機制的發電機，能藉由連接於轉子的散熱葉輪，以具有強制主動散熱的效果，特別是能對轉子組件位置的熱進行強制主動散熱。 The purpose of the present invention is to provide a generator with a heat dissipation mechanism, which can have the effect of forced and active heat dissipation by means of a heat dissipation impeller connected to the rotor, especially the heat at the position of the rotor assembly can be forced and actively dissipated.
為了達成上述目的，本發明提供一種具有散熱機制的發電機，一定子組件；一轉子組件，被該定子組件圍繞，且該轉子組件能相對於該定子組件旋轉；一轉軸，設置於該轉子組件；以及至少一散熱葉輪，連接於該轉子組 件且能跟隨該轉子組件旋轉；其中，該至少一散熱葉輪經由跟隨該轉子組件旋轉而產生散熱氣流。 In order to achieve the above object, the present invention provides a generator with a heat dissipation mechanism, a stator assembly; a rotor assembly surrounded by the stator assembly, and the rotor assembly can rotate relative to the stator assembly; a rotating shaft disposed on the rotor assembly ; and at least one cooling impeller, connected to the rotor set and can rotate with the rotor assembly; wherein, the at least one heat dissipation impeller generates heat dissipation airflow by following the rotation of the rotor assembly.

有關本發明的詳細說明和技術內容，配合圖式說明如下，然而所附圖式僅提供參考與說明用，非用以限制本發明。 The detailed description and technical content of the present invention are described below in conjunction with the drawings. However, the accompanying drawings are only for reference and description, and are not intended to limit the present invention.
如圖1和圖2所示，本發明提供一種具有散熱機制的發電機(以下簡稱發電機)，包括：一定子組件2、一轉子組件3、一轉軸4以及至少一散熱葉輪5。
As shown in FIG. 1 and FIG. 2 , the present invention provides a generator with a heat dissipation mechanism (hereinafter referred to as a generator), including: a
定子組件2圍繞轉子組件3。轉軸4設置於轉子組件3，並使轉子組件3能相對於定子組件2旋轉。其中，轉子組件3沿轉軸4的長度方向具有二端面31，且還能一體成型有多數矽鋼片(未標元件符號)，各矽鋼片上皆纏繞有線圈C，各端面31皆自定子組件2裸露。
The
散熱葉輪5則連接於轉子組件3，使散熱葉輪5能跟隨轉子組件3旋轉。
The
藉此，只要啟動本發明發電機運轉，轉子組件3就能一如既往地相對於定子組件2旋轉而發電，同時由於散熱葉輪5係連接於轉子組件3，使散熱葉輪5能跟隨轉子組件3旋轉而產生具有強制主動散熱效果的散熱氣流，這散熱
氣流則將發電機在運轉時所產生的熱給強制散逸，特別是能對轉子組件3位置的熱進行強制主動散熱。
Thereby, as long as the generator of the present invention is started to operate, the
散熱葉輪5可為一個或兩個以上，於本實施例中則以兩個散熱葉輪5為例進行說明。較佳而言，各散熱葉輪5係分別連接於各端面31，也就是散熱葉輪5係與轉子組件3的旋轉方向相應配置且自定子組件2外露(如圖所示者，散熱葉輪5係位於定子組件2之外)；需說明的是，此二散熱葉輪5所產生的散熱氣流係可朝同一方向流動，也可分別朝兩個不同方向流動，且這兩個不同方向係包含除了彼此相向以外的其它方向。此外，本發明並不限制散熱葉輪5以何種方式連接於轉子組件3，例如可將散熱葉輪5一體成型於轉子組件3，又或是將散熱葉輪5固定於轉子組件3；其中，以固定方式而言，則能以固定架6將散熱葉輪5固定於轉子組件3的端面31。
There may be one or more than two
散熱葉輪5較佳還可開設(例如居中開設)有一穿孔52，轉軸4則可旋轉地穿過穿孔52，且轉軸4的外緣與穿孔52的內緣之間係彼此遠離而共同形成一間隔空間D，也就是轉軸4與穿孔52彼此互不接觸且保持有間隔空間D。藉由這間隔空間D，以將原本滯留於轉子組件3位置的熱，得以全部跟著空氣從間隔空間D排出，大幅提升散熱效率。
Preferably, the
散熱葉輪5得能開設上述穿孔52的原因在於：散熱葉輪5並非連接於轉軸4，而是連接於轉子組件3，使散熱葉輪5得以成為一無輪轂式葉輪且包含有彼此相連的多數葉片51，進而得能在原輪轂位置開設上述穿孔52。
The reason why the
本發明發電機還包括一外殼1。外殼1具有二樞接部11(此二樞接部11分別位於外殼1的兩端之內)且還開設有至少一散熱孔組12，散熱孔組12可為一個或兩個以上，於本實施例中則以兩個散熱孔組12為例進行說明，每一散熱孔組12包含複數孔體(未標示元件符號)。
The generator of the present invention also includes a
定子組件2設置於外殼1的內壁。轉軸4如跨橋般樞接於外殼1的二樞接部11之間且將轉子組件3架設於定子組件2內。各散熱葉輪5分別對應各散熱孔組12配置，例如如圖所示讓散熱孔組12位於所述散熱氣流的流動方向上。
The
藉此，各散熱葉輪5經由跟隨旋轉所產生的散熱氣流，即能以強制主動方式對本發明發電機進行散熱。
In this way, each
在圖式未繪示的其它實施例中，前述外殼1具有位於前述兩端(這兩端內具有樞接部11)之間的一中段部(未標示元件符號)，前述定子組件2則與外殼1的所述中段部彼此一體成型，藉以減少構件數量且減少製程。較佳而言，定子組件2和外殼1的所述中段部係以多數矽鋼片沿轉軸4的長度方向彼此相疊而成。
In other embodiments not shown in the drawings, the
綜上所述，本發明相較於先前技術係具有以下功效：(一)、藉由散熱葉輪5，以具有強制主動散熱的效果，特別是能對轉子組件3位置的熱進行強制主動散熱。(二)、藉由散熱葉輪5係連接於轉子組件3而非連接於轉軸4，以能在散熱葉輪5開設穿孔52，且穿孔52內緣與轉軸4外緣之間共同形成間隔空間D，以將原本滯留於轉子組件3位置的熱，得以全部跟著空氣從間隔空間D排出，大幅提升散熱效率。(三)、藉由散熱葉輪5並無輪轂的設置，使散熱葉輪5與轉子組件3之間的間隙縮小，進而縮小本發明發電機的體積。
To sum up, compared with the prior art, the present invention has the following effects: (1) The
以上所述者，僅為本發明之較佳可行實施例而已，非因此即侷限本發明之專利範圍，舉凡運用本發明說明書及圖式內容所為之等效結構變化，均理同包含於本發明之權利範圍內，合予陳明。 The above descriptions are only the preferred feasible embodiments of the present invention, which do not limit the scope of the present invention.
