我科研团队研制出可快充“热池”
Ke Ji Ri Bao· 2026-01-09 00:37
研究团队瞄准接触式传热,给热池内壁做了层超滑处理,让固态的相变材料不粘壁,靠自身重力一直紧 贴底部热源,近距离接受不断传来的热量,使"热池"全程保持高传热速率。该方法不依赖特殊的相变材 料,只通过优化相变热池内壁环境实现高效传热。 这一核心思路最终落地为"全固态复合表面",其由能脉冲加热的薄膜(预热层)与覆盖在薄膜表面 的"类液涂层"(滑移界面)组成。"就像在锅底涂了一层超顺滑的特殊涂层,再用小火快速预热锅底, 把一块黄油放上去。不仅不粘锅,还能自己滑动着快速熔化。"范利武介绍,除此以外相变材料会在自 身重力作用下持续下沉,把熔化产生的液膜压得更薄,全程紧贴加热表面高效传热。"该技术最核心的 优势,是实现了'快充'与'高储'的双赢。"范利武说。 (文章来源:科技日报) 浙江大学能源工程学院研究员范利武团队与其合作者提出全新的"滑移强化接触熔化"机制,用"全固态 复合表面"给相变热池内壁做了个"滑溜溜的改造",为打破储能量大与充放热速度快之间的矛盾,提升 相变热池的性能提供了新思路。相关研究成果8日发表在国际期刊《自然》上。 电池是现代生活不可或缺的设备,而"热池"作为热能存储装置,与电池原理相似,可实现热量的 ...

忽冷忽热,新型极端天气值得警惕——对人体健康的威胁远超以往认知
Ke Ji Ri Bao· 2026-01-08 02:48
国家气候中心气候预测室副主任章大全介绍,自2025年12月以来(截至12月24日),我国已经历4 次冷空气过程,较常年同期偏多1至2次。12月11日至15日的冷空气为今冬首场全国性寒潮,山西岢岚、 辽宁清原、陕西富县等地167个国家基本气象站的气温降幅达到或超过14℃。 "频繁的冷空气过程是气温剧烈波动的主因。"章大全分析指出,近期北极极涡分裂为双中心,北美 上空极涡分中心强度较强,而亚洲北部极涡则相对较弱。同时,近期我国大部地区大气环流较常年偏 强,导致冷空气过程相对频繁,但强度较弱。冷暖频繁交替,就形成了公众切身感受的"气温过山车"。 近日,黑龙江多地居民经历"冰火两重天":前一天还在阳光下感受融融暖意,次日就不得不裹紧厚 羽绒服抵御寒风。剧烈降温导致尚未南迁的燕子来不及飞离,部分被冻伤甚至死亡。 中国气象局医院诊疗中心主任医师江岚从医学角度进一步解释说,极端日际气温变化主要通过两种 途径威胁健康。一方面,剧烈气温波动使人们难以精准把握衣物增减。若穿着过多,汗液浸湿衣物后经 寒风一吹,水分蒸发会迅速带走体表热量,导致体温骤降。此时身体会优先维持核心体温,致使免疫系 统功能暂时减弱,更易感染病毒。 这样的" ...
