如何有效提高济南冲孔字的散热性能

页面更新时间:2015-07-09 10:19 来源:未知 作者:admin 点击:

我们拆解过各种各样的产品。在芯片、液晶面板、各种电子部件的配置等诸多看点中,让小编感受到“真是下了工夫”的地方是散热措施。使用导热管、散热片、均热板等,让容易发热的部件释放出热量,每种产品使用的方法都有着自己的特点,体现了开发者的设计思路。

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.

热辐射散热法的优点是,在机壳密闭而且很薄、热量无法通过对流转移的情况下,可以释放出热量。一些技术人员很早以前就知道这种优点,但充分利用的先例少之又少。不过,据西村陶业介绍,最近采用热辐射散热的LED照明产品有所增加。其中,日本一家照明器具企业将其应用到了从投光器等大型LED照明器具到台灯等小型产品的各种用途。

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..

通过采用热辐射散热,可以提高济南冲孔字 http://www.kangmingda.com/ 投光器的散热效率,无需再使用冷却风扇。不使用冷却风扇可以降低故障风险(风扇因发生某种故障而瘫痪、导致无法散热的风险),而且,因为无需多片状散热片,所以不会积尘,省去了清扫的麻烦。在制造台灯时,通过采用热辐射散热,成功实现了光源附近的外壳的超薄设计。

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.

令人兴趣浓厚的是,无论是大型产品,还是小型产品,康明达向照明器具企业提供的陶瓷电路板基本相同。陶瓷电路板都是长55mm×宽30mm的横长型六边形、厚度为6mm左右,用螺丝把多芯片型LED模块固定在电路板上使用。最大可使用功率为19W的高功率LED模块。大型产品使用多个螺丝将LED模块固定在陶瓷电路板上,小型产品使用1个。陶瓷电路板的材料采用纯度为99.7%的氧化铝,热辐射率为0.97。表面平滑,平均粗糙度为0.5μm,直接用螺丝把LED模块固定在电路板表面。

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.

与金属电路板和印刷电路板等相比,陶瓷电路板面临的阻碍在于成本高。但是,如果能够借助陶瓷电路板的通用化提高量产效果,就可以在某种程度上遏制成本的上涨。这需要增加量产数量,但截至目前,大量生产尚未展开,原因是企业对陶瓷电路板的高成本心存忌惮。

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.

针对这种情况,康明达表示,采用陶瓷电路板后,用来安装LED模块的电路板和散热片等散热部件的总成本可以降低,今后打算以这种散热成本为卖点做宣传。该公司之所以如此自信,是因为采用该公司产品的照明器具企业在比较了采用陶瓷电路板的产品和采用传统散热设计的产品、并考虑了总成本后,无一例外地选择了陶瓷电路板。对于压缩总成本的思路能否普及,济南冲孔字小编今后也会密切关注。或许,可以通过形状简洁的LED照明器具是否增加来预测普及的程度。

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.
