【摘要】：大功率LED特別是集成式大功率LED越來(lái)越多的應(yīng)用于照明行業(yè)，作為發(fā)光元件，具有發(fā)光效率高，壽命長(zhǎng)的特點(diǎn)。由于LED芯片對(duì)溫度的要求嚴(yán)格，在使用過(guò)程如何有效的散熱是LED發(fā)展的關(guān)鍵問(wèn)題，傳統(tǒng)集成大功率LED散熱器由于質(zhì)量大，散熱效率不高，在使用過(guò)程有很大的局限性。 本文基于散熱器的設(shè)計(jì)方法，引入新型的熱管技術(shù)，結(jié)合傳統(tǒng)的散熱器，設(shè)計(jì)了一種新型的熱管散熱器，并對(duì)改進(jìn)后的熱管散熱器翅片部分進(jìn)行優(yōu)化，具體工作如下： 1.通過(guò)研究熱管的結(jié)構(gòu)，分析熱管的散熱過(guò)程，提出把熱管復(fù)雜的換熱過(guò)程用簡(jiǎn)單的熱傳導(dǎo)來(lái)代替，用分段式的當(dāng)量導(dǎo)熱系數(shù)定義熱管各個(gè)部分的導(dǎo)熱效果，大大簡(jiǎn)化熱管散熱器數(shù)值計(jì)算，為散熱器的數(shù)值優(yōu)化計(jì)算提供了理論基礎(chǔ)。 2.在原有散熱器的基礎(chǔ)上，對(duì)散熱器進(jìn)行結(jié)構(gòu)改進(jìn)，在冷凝段增加翅片以加大冷凝段的熱交換面積，提高熱管冷凝段的散熱能力，并對(duì)冷凝段的翅片進(jìn)行正交優(yōu)化，分析翅片各個(gè)尺寸對(duì)散熱器質(zhì)量和散熱效果的影響，最后得到比較好的優(yōu)化結(jié)果。 3.對(duì)試制的樣品進(jìn)行試驗(yàn)，結(jié)果證明簡(jiǎn)化模型能夠比較準(zhǔn)確的反映熱管散熱器的散熱過(guò)程；通過(guò)對(duì)改進(jìn)后散熱器的測(cè)點(diǎn)溫度測(cè)定，，表明了優(yōu)化后的散熱器質(zhì)量較輕，散熱器效果較好，達(dá)到了優(yōu)化的目的。
[Abstract]:The high power LED, especially the integrated high-power LED, is more and more used in the lighting industry. As a light emitting element, it has the characteristics of high luminous efficiency and long life. Because of the strict requirements for the temperature, the effective heat dissipation of the LED chip is the key problem of the development of the LED. The traditional integrated high-power LED radiator is of large quality and heat dissipation. The efficiency is not high, and there is a great limitation in the use process.
In this paper, based on the design method of radiator, a new type heat pipe radiator is designed with the new heat pipe technology and the traditional radiator, and the fin parts of the improved heat pipe radiator are optimized. The specific work is as follows:
1. by studying the structure of the heat pipe and analyzing the heat transfer process of the heat pipe, it is proposed that the heat transfer process is replaced by a simple heat transfer process. The heat conduction effect of each part of the heat pipe is defined by the sectional equivalent thermal conductivity, and the numerical calculation of the heat pipe radiator is simplified, which provides the theoretical basis for the numerical optimization calculation of the heat exchanger.
2. on the basis of the original radiator, the structure of the radiator is improved. The heat exchange area of the fins is added in the condensing section to increase the heat exchange area of the large cold condensing section, and the heat dissipation capacity of the condensing section of the heat pipe is improved. The fins of the condensing section are optimized orthogonal, and the influence of the size of the fins on the quality of the radiator and the heat dissipation is analyzed. Finally, the better advantages are obtained. Turn the result.
3. the test samples are tested. The results show that the simplified model can accurately reflect the heat dissipation process of the heat pipe radiator. Through the measurement of the measured point temperature of the improved radiator, the optimized radiator is lighter and the effect of the radiator is better, and the aim of the optimization is achieved.
