散熱元件Heat sink
一種散熱元件，尤指一種提升散熱元件焊接之結合度及密閉性的散熱元件。A heat dissipating component, especially a heat dissipating component that improves the bonding degree and sealing property of a heat dissipating component.
均溫板或平板式熱管普遍被使用在作為熱傳導元件使用，這兩項熱傳導元件具有高導熱之特性，由於內部真空密閉腔室填充工作液體使得透過氣液兩相特性之轉換快速達到熱傳導之效果，均溫板及平板式熱管係透過以上、下至少兩金屬板體進行疊合後進行封邊注水抽真空封閉等作業，均溫板及平板式熱管最常使用之材料係為銅、鋁、不銹鋼等金屬材質，其中又以銅最為常使用，因銅本身具有高熱傳導特性，故最常被使用。 多數均溫板及平板式熱管主要透過擴散接合(Diffusion Bonding)與硬焊(Brazing)及點焊之方式進行封邊之工作，而擴散接合(Diffusion Bonding)與硬焊(Brazing)適用於多數材質，但若兩種相異材質之結合例如銅與鋁或銅與不銹鋼則並不適用擴散接合此項工法。 點焊的缺點在於雖可連續加工但無法完整密閉封邊，則若使用在均溫板封邊之工作則無法維持內部腔室之真空度以及工作液體容易因為密閉性不佳而產生外洩，進而失去熱傳導效果。 亦有業者透過使用電阻輪焊之方式進行焊接接合的工作，而現行電阻輪焊 之均溫板或平板式熱管，主要由一上板3a（表面積較小）及一下板3b（表面積較大）相互疊合後，再透過於上、下板3a、3b搭接重合的直角角落位置進行電阻輪焊(Fillet Weld)（如第1、1a圖所示），雖電阻輪焊可提供大小不一致的上、下板3a、3b的焊接結合，但習知電阻輪焊的焊接方式及材料的結合處仍具有缺點，如上、下板3a、3b為了形成可提供焊接之垂直角落部位，選擇上板3a小於下板3b，故上、下板3a、3b必須要準確對位，甚至必須有專用治具對該上、下板3a、3b進行定位。 再者，當電阻輪焊之焊接路徑當遇到圓角時則會因路徑必需由直線慢慢修正為弧形，則會採用多段短直線進行拼湊為弧形之路徑，故使電阻輪焊之部位重複或停留時間增長，令材料過度燒熔甚至破壞至均溫板或平板式熱管內部之毛細結構或令內部腔室縮減等缺點，並且為了形成可焊接之垂直角落部位，則必須選用形狀大小不同之上、下板3a、3b，使下板3b外緣唇邊容易產生多餘無效之唇邊，形成材料浪費之缺點。 習知具有下列缺點： 1. 材料浪費； 2. 密閉性不佳； 3. 必須額外進行定位； 4. 異材料不易結合。Mean temperature plate or flat plate heat pipe is generally used as a heat conduction element. These two heat conduction elements have high heat conduction characteristics, and the internal vacuum sealed chamber is filled with the working liquid to quickly achieve the heat conduction effect through the conversion of gas-liquid two-phase characteristics. The temperature-averaging plate and the flat-plate heat pipe are superposed by the above and below at least two metal plates, and then sealed and sealed by water injection and vacuum sealing. The materials most commonly used for the uniform temperature plate and the flat heat pipe are copper and aluminum. Metals such as stainless steel, which are most commonly used in copper, are most commonly used because of their high heat transfer characteristics. Most thermostats and flat-plate heat pipes are mainly used for edge banding by diffusion bonding (Diffusion Bonding) and brazing and spot welding. Diffusion Bonding and Brazing are suitable for most materials. However, if a combination of two different materials such as copper and aluminum or copper and stainless steel is not suitable for diffusion bonding. The disadvantage of spot welding is that although it can be processed continuously but cannot be completely sealed, if the work of sealing the edge of the temperature equalizing plate is used, the vacuum of the internal chamber cannot be maintained and the working fluid is easily leaked due to poor airtightness. In turn, the heat conduction effect is lost. Some manufacturers also use the resistance wheel welding method to carry out the welding joint work, while the current resistance wheel welding homogenization plate or flat plate heat pipe mainly consists of an upper plate 3a (smaller surface area) and a lower plate 3b (large surface area). After superimposing each other, the welding wheel welding (Fillet Weld) is performed by overlapping the right and right corners of the upper and lower plates 3a and 3b (as shown in Figs. 1, 1a), although the resistance wheel welding can provide inconsistent sizes. The welding of the upper and lower plates 3a, 3b is combined, but the welding method of the conventional resistance wheel welding and the joint of the materials still have disadvantages. For the upper and lower plates 3a, 3b, in order to form a vertical corner portion capable of providing welding, the upper plate 3a is selected. It is smaller than the lower plate 3b, so the upper and lower plates 3a, 3b must be accurately aligned, and even a special jig must be positioned to position the upper and lower plates 3a, 3b. Furthermore, when the welding path of the resistance wheel welding encounters a rounded corner, the path must be slowly corrected to a curved shape by a straight line, and a plurality of short straight lines are used to form a curved path, so that the resistance wheel welding is performed. The repetition of the part or the increase of the residence time causes the material to be excessively melted or even destroyed to the capillary structure inside the uniform temperature plate or the flat heat pipe or to reduce the internal cavity, and in order to form a weldable vertical corner portion, the shape size must be selected. Different upper and lower plates 3a, 3b make the outer edge of the lower plate 3b easy to produce excess invalid lips, which is a disadvantage of material waste. Conventional has the following disadvantages: 1. Material waste; 2. Poor airtightness; 3. Additional positioning is required; 4. Different materials are not easily combined.
