            如何有效提高濟南沖孔字的散熱性能

            我們拆解過各種各樣的產品。在芯片、液晶面板、各種電子部件的配置等諸多看點中,讓小編感受到“真是下了工夫”的地方是散熱措施。使用導熱管、散熱片、均熱板等,讓容易發熱的部件釋放出熱量,每種產品使用的方法都有著自己的特點,體現了開發者的設計思路。

            We have dismantled all kinds of products. In the chip, LCD panels, a variety of electronic components, such as configuration, and many other things, so that a small sense of being really the next time, the place is heat dissipation measures. Using heat conduction tube, heat sink, heat plate, etc., so that easy to heat the part of the release of heat, each product using the method has its own characteristics, reflects the development of the design ideas.

            熱輻射散熱法的優點是,在機殼密閉而且很薄、熱量無法通過對流轉移的情況下,可以釋放出熱量。一些技術人員很早以前就知道這種優點,但充分利用的先例少之又少。不過,據西村陶業介紹,最近采用熱輻射散熱的LED照明產品有所增加。其中,日本一家照明器具企業將其應用到了從投光器等大型LED照明器具到臺燈等小型產品的各種用途。

            The advantage of thermal radiation heat radiation method is that it can release the heat in the case of the case that the shell is confined and very thin and heat can not be transferred. Some technical personnel have long known this advantage, but the full use of the precedent of less and less. However, according to the village pottery industry, LED lighting products recently increased by thermal radiation. Among them, a Japanese lighting appliance enterprises will be applied to all kinds of small products, such as light and other large LED lighting apparatus to lamps, etc..

            通過采用熱輻射散熱,可以提高濟南沖孔字 http://www.xubclan.com/ 投光器的散熱效率,無需再使用冷卻風扇。不使用冷卻風扇可以降低故障風險(風扇因發生某種故障而癱瘓、導致無法散熱的風險),而且,因為無需多片狀散熱片,所以不會積塵,省去了清掃的麻煩。在制造臺燈時,通過采用熱輻射散熱,成功實現了光源附近的外殼的超薄設計。

            By the use of thermal radiation heat, can improve the efficiency of the thermal efficiency of the Ji'nan punching word, no longer use cooling fan. Do not use cooling fan can reduce the risk of failure (fan due to the occurrence of a fault to a standstill, resulting in cannot the risk of heat), and because there is no need to flake fin, so no dust, eliminating the need for cleaning the trouble. In the manufacture of table lamp, by the use of heat radiation, the successful implementation of the light source near the shell of the ultra-thin design.

            令人興趣濃厚的是,無論是大型產品,還是小型產品,康明達向照明器具企業提供的陶瓷電路板基本相同。陶瓷電路板都是長55mm×寬30mm的橫長型六邊形、厚度為6mm左右,用螺絲把多芯片型LED模塊固定在電路板上使用。最大可使用功率為19W的高功率LED模塊。大型產品使用多個螺絲將LED模塊固定在陶瓷電路板上,小型產品使用1個。陶瓷電路板的材料采用純度為99.7%的氧化鋁,熱輻射率為0.97。表面平滑,平均粗糙度為0.5μm,直接用螺絲把LED模塊固定在電路板表面。

            It is interesting to be interested, whether it is a large product, or small products, Kang Mingda to the lighting apparatus to provide the same as the ceramic circuit board. Ceramic circuit board is a long 55mm x width 30mm, the thickness of the transverse 6mm, with a screw to the multi chip LED module is fixed on the circuit board. The maximum available power for the 19W high power LED module. Large products use a number of screws to the LED module is fixed on the ceramic circuit board, the use of small products 1. Ceramic circuit board materials using the purity of 99.7% of alumina, thermal radiation rate of 0.97. The average roughness of the surface is 0.5 m, and the LED module is fixed on the circuit board.

            與金屬電路板和印刷電路板等相比,陶瓷電路板面臨的阻礙在于成本高。但是,如果能夠借助陶瓷電路板的通用化提高量產效果,就可以在某種程度上遏制成本的上漲。這需要增加量產數量,但截至目前,大量生產尚未展開,原因是企業對陶瓷電路板的高成本心存忌憚。

            In comparison with the metal circuit board and the printed circuit board, the ceramic circuit board is faced with the high cost. However, if the use of ceramic circuit board for the purpose of improving the production efficiency, it can be in a certain extent to curb the cost of rising. The need to increase the number of production, but up to now, mass production has not yet commenced. The reason is that enterprise of ceramic circuit board of high cost wary.

            針對這種情況,康明達表示,采用陶瓷電路板后,用來安裝LED模塊的電路板和散熱片等散熱部件的總成本可以降低,今后打算以這種散熱成本為賣點做宣傳。該公司之所以如此自信,是因為采用該公司產品的照明器具企業在比較了采用陶瓷電路板的產品和采用傳統散熱設計的產品、并考慮了總成本后,無一例外地選擇了陶瓷電路板。對于壓縮總成本的思路能否普及,濟南沖孔字小編今后也會密切關注?;蛟S,可以通過形狀簡潔的LED照明器具是否增加來預測普及的程度。

            In view of this situation, Kang Mingda said that the ceramic circuit board, to LED module of circuit board and heat sink, such as the heat radiating component of the total cost of installation can be reduced, the future plan to in this heat dissipation cost as a selling point to do publicity. The reason why the company was so confident, because the use of the products of lighting apparatus enterprises in compared with ceramic circuit board products and the traditional thermal design of products, and to consider the total cost, without exception, chose ceramic circuit board. For the total cost of the compression of the idea of universal, Ji'nan punching word small series will be closely watched in the future. Perhaps, the shape of the LED lighting can be simple to predict whether the increase in popularity.
