THERMAL MANAGEMENT散熱材料

匯眾電子提供一系列具有極高導熱功能的產品。包括散熱膏(脂),導熱膠粘膠和導熱封裝材料。主要應用于電子及相關設備的散熱,保證設備的穩定工作。

Wilkon offers a range of products with extremely high thermal conductivity, including thermal grease, thermal conductive adhesive and thermal encapsulation materials. These products are mainly used in thermal dissipation of electronic and related equipment to ensure stable operation of the device.

在電子電氣領域,由于集成技術和微封裝技術的發展,電子元件和設備向小型化與微型化發展,這種趨勢的后果便是在有限的體積內產生了更多的熱量,如果熱量不能及時的散發,熱量積聚過多將會導致元件工作溫度升高,影響其正常工作,嚴重時還會使電子元件失效。統計資料表明電子元件溫度每升高2℃,可靠性下降10 %;溫升50℃時的壽命只有溫升25℃時的1/6。

In the electrical and electronic fields, with the development of integration and micro-encapsulation technology, electronic components and equipment are more inclined to miniaturization and microminiaturization. The consequence of this trend is that more heat is generated within a limited volume. If the heat cannot be dissipated timely, excessive heat accumulation will cause rising working temperature of components, thus affecting its normal work and even causing electronic component failure. Statistics show that if the electronic component temperature is increased by 2℃, its reliability will be decreased by 10%; if temperature is increased by 50℃, its lifetime is only 1/6 compared with temperature increased by 25%.

通常會使用金屬散熱器消除部件間產生的熱量,散熱器形成較大的表面積或者是組件外部的一部分,熱部件通常用機械方式連接金屬。這種方式的局限是在結合處的間隙中存在空氣。空氣是熱的不良導體,嚴重影響散熱效率。通常會使用柔性導熱材料填充這些空隙,去除空氣。我們提供的產品具有優良的散熱性能,保證熱能以最快的速度從部件流到金屬散熱片。

Usually a metal heat sink will be used to dissipate the heat away generated by components. It will form a larger surface area or part of the external components. The thermal components are usually connected to the metal mechanically. The limitation of this approach is the presence of air in the gap at the junction. Air is a poor conductor of heat, and will seriously affect the thermal performance. A flexible thermally conductive material will be typically used to fill the gaps to remove air. Our products have excellent thermal performance, ensuring the heat flowing from components to the metal heat sinks in the fastest speed.

在太陽能采熱系統中關鍵的問題是以最少的損耗最多地傳導熱量。為此,我們提供的超強熱導膏(導熱率大于3.0W/m.k)是解決該問題最理想的產品。

A key issue in the solar heating system is to transfer the most heat at minimal loss. Our superior thermal grease (thermal conductivity greater than 3.0W/m.k) is an ideal product to solve this problem.

匯眾電子提供不含硅的散熱劑,無硅導熱脂是由無硅基礎油和其他填料組成的膏狀導熱媒介材料。與傳統的導熱硅脂相比,無硅導熱材料可以解決導熱硅脂在使用過程中隨著時間的推移而釋放游離的硅份子并產生遷移的問題。

Wilkon provides silicon-free thermal grease, which is a thermally conductive grease composed of silicone-free base oils and other fillers. Compared with traditional thermal grease, silicone-free thermal grease can solve the problem of releasing dissociative silicon molecules and migration over time during the use of traditional thermal grease.

含硅導熱材料所產生的遷移通常會為電子產品帶來兩種負面的影響,一種是使硅脂與散熱器的連接面出現很多凹陷,降低與散熱器的接觸面積進而減弱材料的導熱性能;另一種是游離硅份子會污染電子產品的開關觸點,在高壓下在觸點的表面形成高絕緣氧化硅,導致觸點接觸不良。無硅導熱材料常用于高技術以及高成本的電子,包括通訊和計算機等高精密的制造工業。

Migration generated by silicon-free thermally conductive material usually has two negative impacts on electronic products. One impact is that many indentations are generated on the junction surface of silicone grease and the heat sink, reducing the contact area with the heat sink and thus weakening the thermal conductivity of the material. Another impact is that dissociative silicon molecules will contaminate the switch contacts of electronic products. At high pressure, insulating silicon oxide will be formed on the contact surface, resulting in poor contacts. Silicon-free thermally conductive materials are commonly used in high-tech and high-cost electronics, including high-precision manufacturing industries like communications and computers.

導熱型粘合膠具有優異的基材粘合強度。利用粘合膠的基材粘合性能和導熱性能,能夠牢固的將散熱器固定在發熱元件上并且提供散熱功能。大部分這種材料為雙組份和單組份結構。雙組份結構的材料存儲簡單,價格便宜。而單組份結構則使用簡單,但通常需要高溫下進行固化。

Thermal conductive adhesive has excellent substrate adhesion strength. With its substrate adhesive property and thermal conductivity, the thermal conductive adhesive can fix the heat sink firmly on the heating element and provide thermal dissipation function. Most of these materials are two-part and one-part systems. Two-part materials are easy and cheap to store, while one-part materials are easy to use, but usually require high temperatures for curing.

除了傳統的用于間隙填充的柔性導熱劑或導熱型粘合膠,匯眾電子也提供一些具有高導熱性能的用于澆注密封的樹脂。這類型材料除了能夠解決電子產品工作過程中可能出現的振動、防水和增強絕緣強度等功能外,還可以輔助解決電子產品的散熱問題,例如個別使用了MOS管和大功率變壓器的電子產品。

Apart from traditional flexible heat-transfer agents or thermal conductive adhesives for gap filling, Wilkon also provides resins with high thermal conductivity for pouring and sealing. This kind of material can ensure anti-vibration, waterproof and enhance dielectric strength during operation of the electronic products, but also assist in solving the thermal dissipation problem of electronic products, such as those using MOS tube and high-power transformer.
