Adopts the following technical proposal: the laser head cooling device for laser cutting, set up a water wall in the outer wall of the laser head, water wall axial section shape is circular, water wall and the bottom surface of the outer wall of the laser head is arranged outside the upper wall water injection hole, water hole through a duct with constant speed water injection, water injection hole is arranged at the upper part of the water connection line, water connection line is connected with the water absorbing material. The present invention by uniform injection water flow into the water wall and the outer wall of the laser head in the water injection hole, the laser head overheating, the rapid evaporation of water, so the water evaporation endothermic cooling, the speed is too slow, the excess water through the water connection line absorbed water absorbent material, automatic heat dissipation. The invention has the advantages that the heat dissipation of the laser head can be realized by the continuous injection of water into the tube, and the radiating efficiency is high.
【技術(shù)實(shí)現(xiàn)步驟摘要】
本專利技術(shù)涉及激光切割領(lǐng)域,具體涉及一種激光切割激光頭的散熱裝置。
技術(shù)介紹
激光切割是將從激光器發(fā)射出的激光,經(jīng)光路系統(tǒng),聚焦成高功率密度的激光束。激光束照射到工件表面,使工件達(dá)到熔點(diǎn)或沸點(diǎn),同時(shí)與光束同軸的高壓氣體將熔化或氣化金屬吹走。隨著光束與工件相對位置的移動(dòng),最終使材料形成切縫,從而達(dá)到切割的目的。由于激光所攜帶的功率密度較大,當(dāng)激光照射在反射鏡和聚焦透鏡上時(shí),即使反射鏡和聚焦透鏡只吸收極少部分激光的能量,但是還是會(huì)導(dǎo)致反射鏡、聚焦透鏡和通光管發(fā)熱。尤其是在激光頭長時(shí)間工作時(shí),會(huì)導(dǎo)致通光管溫度升高,對聚焦透鏡和反射鏡造成損害。所以需要一種散熱效率高的用于激光切割激光頭的散熱裝置。
技術(shù)實(shí)現(xiàn)思路
本專利技術(shù)提供了一種散熱效率高的激光切割激光頭散熱裝置。為了解決上述技術(shù)問題,本專利技術(shù)采用如下技術(shù)方案:一種激光切割激光頭散熱裝置, 在激光頭外壁設(shè)置一個(gè)注水壁,注水壁軸截面形狀為圓環(huán)形,注水壁底面與激光頭外壁相連,注水壁上端外側(cè)設(shè)置注水孔,注水孔通過導(dǎo)管勻速注水,注水孔上端設(shè)置吸水性連接線,吸水性連接線連接吸水性材料。進(jìn)一步的,所述吸水性材料為海綿。進(jìn)一步的,所述注水壁厚度為1mm。進(jìn)一步的,所述注水壁與激光頭外壁距離為2mm。本專利技術(shù)通過在注水孔中勻速注水流進(jìn)注水壁與激光頭外壁,激光頭過熱時(shí),水分快速蒸發(fā),因此吸熱降溫,水分蒸發(fā)速度過慢時(shí),多余的水通過吸水性連接線被吸水性材料吸收,實(shí)現(xiàn)自動(dòng)散熱。本專利技術(shù)的有益效果是:通過導(dǎo)管勻速注水散熱,實(shí)現(xiàn)了對激光頭的自動(dòng)散熱,且散熱效率高。附圖說明下面結(jié)合附圖和具體實(shí)施方式對本專利技術(shù)作進(jìn)一步描述:圖1是本專利 ...
