Description

風扇組合 Fan combination

本發明涉及一種風扇組合，尤其涉及一種用於對發熱電子元件散熱之風扇組合。 The present invention relates to a fan assembly, and more particularly to a fan assembly for dissipating heat from a heat-generating electronic component.

隨著資訊產業之飛速發展，中央處理器等發熱電子元件向著高性能、高速度化發展，遂致使發熱電子元件產生之熱量越來越多，若不及時將該等熱量散去，將會嚴重影響發熱電子元件之可靠度及使用壽命，甚至造成發熱電子元件之損壞。故，散熱問題已成為眾多電子產品中之重要問題之一。為此，業界通常在電子產品中加裝一風扇以對發熱電子元件散熱，在單一風扇不能滿足散熱需求時，還常常會採用風扇組合來散熱。 With the rapid development of the information industry, the heat-generating electronic components such as the central processing unit are developing toward high performance and high speed, resulting in more and more heat generated by the heat-generating electronic components. If the heat is not dissipated in time, it will be serious. Affects the reliability and service life of the heat-generating electronic components, and even causes damage to the heat-generating electronic components. Therefore, the heat dissipation problem has become one of the important issues in many electronic products. To this end, the industry usually installs a fan in the electronic product to dissipate heat from the heat-generating electronic components. When a single fan cannot meet the heat dissipation requirements, a fan combination is often used to dissipate heat.

該風扇組合由兩個或兩個以上之風扇組成，每一風扇包括一扇框及收容於扇框中之一扇輪，相鄰兩風扇之扇框藉由複數外來之連接件，如螺釘等連接在一起。惟，該等連接件不僅增加了該風扇組合組裝時之難度及工時，且增加了生產之成本。 The fan assembly is composed of two or more fans, each fan includes a frame and a fan wheel housed in the fan frame, and the fan frames of the adjacent two fans are connected by a plurality of external connectors, such as screws. connected. However, the connectors not only increase the difficulty and time of assembly of the fan assembly, but also increase the cost of production.

有鑒於此，有必要提供一種組裝方便且成本較低之風扇組合。 In view of this, it is necessary to provide a fan assembly that is easy to assemble and low in cost.

一種風扇組合，包括一第一風扇及與該第一風扇結合之一第二風扇，該第一風扇包括一第一扇框，該第二風扇包括一第二扇框，該第一扇框之頂端設有至少一對面對面設置之第一固定片，每一第一固定片上設有向與其配對之另一第一固定片突伸之一第一鉤部，該第二扇框之底端設有至少一對背對背設置之第二固定片，每一第二固片上設有向與其配對之另一第二固定片相反方向突伸之一第二鉤部，該至少一對第二固定片位於該至少一對第一固定片之間，並且該至少一對第二固定片之第二鉤部分別鉤住該至少一對第一固定片之第一鉤部。 A fan assembly includes a first fan and a second fan coupled to the first fan, the first fan includes a first fan frame, and the second fan includes a second fan frame, the first fan frame The top end is provided with at least one pair of first fixing pieces disposed face to face, each The first fixing piece is provided with one first hook portion protruding from another first fixing piece paired therewith, and the bottom end of the second frame frame is provided with at least one pair of second fixing pieces disposed back to back, each second solid The sheet is provided with a second hook portion protruding in a direction opposite to another second fixing piece paired therewith, the at least one pair of second fixing pieces being located between the at least one pair of first fixing pieces, and the at least one pair of second The second hook portion of the fixing piece respectively hooks the first hook portion of the at least one pair of first fixing pieces.

與習知技術相比，該風扇組合藉由設在第一風扇與第二風扇上帶有鉤部之固定片而連接在一起，組裝時只需藉由按壓之操作即可，操作方便，並且該第一、第二固定片分別與第一、第二扇框一體成型，不需配置外來之連接件，降低了生產成本。 Compared with the prior art, the fan assembly is connected by a fixing piece provided with a hook portion on the first fan and the second fan, and can be operated only by pressing operation during assembly, and is convenient to operate, and The first and second fixing pieces are integrally formed with the first and second fan frames, respectively, and the external connecting members are not required, which reduces the production cost.

The sheet 113 is applied to the corresponding opening 217 from the first opening 218 of the second frame 21, and the inclined surface 116 of the first fixing piece 113 and the inclined surface 216 of the corresponding second fixing piece 213 are relatively slid. The first and second fixing pieces 113 and 213 are elastically deformed laterally, that is, each pair of first fixing pieces 113 is expanded toward the outer side of the pair of first fixing pieces 113, and each pair of second fixing pieces 213 is opposite to the pair of second fixing pieces. Referring to FIG. 4, when the hook portion 115 of each pair of first fixing pieces 113 slides over the hook portion 215 of the corresponding pair of second fixing pieces 213, the first fixing piece 113 and the second fixing portion The sheet 213 is restored to the original shape, and the hook portion 115 of each pair of the first fixing pieces 113 is hooked to the hook portion 215 of the corresponding one of the second fixing pieces 213, and each The second fixing piece 213 is positioned between the corresponding one of the first fixing pieces 113, and each of the first fixing pieces 113 on the first fan 10 and the corresponding one of the second fixing pieces 213 on the second fan 20 are The second opening 219 of the notch 217 where the pair of second fixing pieces 213 is located is exposed, so that the fan assembly 100 can operate the first and second fixing pieces 113 and 213 when disassembling. Work.

上述實施例中，缺槽217設置在第二風扇20之扇框21之凸緣212上，使第二固定片213設置在缺槽217內，而第一固定片113從第一風扇10之凸緣112上直接向上延伸。當然，本發明不限於上述設計，請參照圖5，該缺槽217亦可以改由設置在第一風扇10之扇框11之凸緣112上，使第一固定片113設置在缺槽217內，而在第二風扇20之扇框21之凸緣212上不設置缺槽217，使第二固定片213從凸緣212上直接向下延伸。 In the above embodiment, the notch 217 is disposed on the flange 212 of the fan frame 21 of the second fan 20, so that the second fixing piece 213 is disposed in the notch 217, and the first fixing piece 113 is convex from the first fan 10. The edge 112 extends directly upward. Of course, the present invention is not limited to the above design. Referring to FIG. 5, the notch 217 may also be disposed on the flange 112 of the fan frame 11 of the first fan 10, so that the first fixing piece 113 is disposed in the slot 217. The notch 217 is not provided on the flange 212 of the fan frame 21 of the second fan 20, so that the second fixing piece 213 extends directly downward from the flange 212.

The operation is convenient, and the first and second fixing pieces 113 and 213 are integrally formed with the first and second fans 10 and 20 respectively, and the connection mode of the connecting member is separately arranged, thereby greatly saving the production cost. In addition, the first The second fixing pieces 113 and 213 can be elastically deformed. The elastic deformation variables required for each of the fixing pieces 113 and 213 are relatively small during assembly, thereby reducing the breakage of the first and second fixing pieces 113 and 213. The possibility.
