Description
本發明涉及一種散熱模組及其固定方法，特別是一種用於對電子產品散熱的散熱模組及其固定方法。 The invention relates to a heat dissipation module and a fixing method thereof, in particular to a heat dissipation module for dissipating heat of an electronic product and a fixing method thereof.
目前全球掀起了筆記本薄型化及平板電腦的熱潮，這些薄型系統在空間受限的情況下，使得散熱模組無法使用傳統的彈簧螺絲組來鎖固，目前一般會採用彈片組以取代彈簧螺絲組。現有的固定散熱模組的彈片組常需借助一板件來實現散熱模組的熱管與彈片的固定配合。彈片通過鉚接、扣接等方式固定於板件上，或者直接與板件一體成型。板件與熱管焊接，並通過彈片所產生的彈力與發熱元件接觸。然而，現有的此種彈片與板件的固定結構由於需要進行鉚接或扣接，導致組裝過程較為繁瑣；並且，板件的使用也會導致材料的增加，從而造成製造成本的上升。而彈片與板件一體成型的結構則由於製造工藝的限制導致所需的材料面積較大，從而也影響到製造成本的控制。此外，由於彈片需要鉚合在板件或壓鑄件上，沒有板件就無法固定彈片在散熱模組上，故難以避免成本高昂的問題。 At present, there is a boom in thin notebooks and tablet PCs in the world. These thin systems can't be locked with traditional spring screw sets in space-constrained situations. Currently, shrapnel sets are generally used instead of spring screw sets. . The existing shrapnel group of the fixed heat dissipating module often needs a plate member to realize the fixed cooperation between the heat pipe and the shrapnel of the heat dissipating module. The elastic piece is fixed to the plate by riveting, fastening, or the like, or directly formed integrally with the plate. The plate is welded to the heat pipe and is in contact with the heat generating component by the elastic force generated by the elastic piece. However, the existing fixing structure of the shrapnel and the plate member requires riveting or fastening because of the need for riveting or fastening, and the assembly process is cumbersome; and the use of the plate member also leads to an increase in material, thereby causing an increase in manufacturing cost. The structure in which the elastic piece and the plate piece are integrally formed has a large material area required due to the limitation of the manufacturing process, thereby also affecting the control of the manufacturing cost. In addition, since the elastic piece needs to be riveted to the plate member or the die-casting member, the elastic piece cannot be fixed on the heat-dissipating module without the plate member, so that it is difficult to avoid the problem of high cost.
因此，有必要提供一種製造成本較低的散熱模組及其固定方法。 Therefore, it is necessary to provide a heat dissipation module with a lower manufacturing cost and a fixing method thereof.
一種散熱模組，用於對安裝在電路板上的電子元件散熱，其包括 一熱管及一彈片結構，該彈片結構包括一直接焊接於熱管上的抵壓部及一固定至電路板的固定部，該彈片結構的抵壓部對該熱管施力使其與電子元件熱接觸。 A heat dissipation module for dissipating heat from electronic components mounted on a circuit board, including a heat pipe and a shrapnel structure, the shrapnel structure comprising a pressing portion directly welded to the heat pipe and a fixing portion fixed to the circuit board, the pressing portion of the shrapnel structure biasing the heat pipe to make thermal contact with the electronic component .
一種散熱模組的固定方法，其步驟包括：提供一熱管及一彈片結構，該彈片結構包括一抵壓部及與一抵壓部連接的固定部；將該彈片結構的抵壓部焊接於該熱管上；將該彈片結構的固定部固定在一電路板上，使抵壓部帶動熱管與電路板上的一電子元件熱接觸。 A method for fixing a heat dissipation module, the method comprising: providing a heat pipe and a spring structure, the spring structure comprising a pressing portion and a fixing portion connected to a pressing portion; welding the pressing portion of the elastic piece structure to the The fixing portion of the elastic structure is fixed on a circuit board, so that the pressing portion drives the heat pipe to be in thermal contact with an electronic component on the circuit board.
由於該散熱模組的彈片結構直接焊接在熱管上，因此無需借助板體來實現彈片與熱管之間的配合固定。由此，可省去傳統的鉚合或扣接工序，從而節省工時並降低成本。 Since the elastic structure of the heat dissipation module is directly welded to the heat pipe, the cooperation between the elastic piece and the heat pipe is not required by the plate body. Thereby, the conventional riveting or fastening process can be omitted, thereby saving man-hours and reducing costs.
