据说由美国能源部主导的能源效率办公室旗下的材料实验团队，找到了两种容易制作的磁化材料，效果比过去的磁化制冷效果还提升50%，他们相信这种由磁热效应为主的家用冷气与冰箱，将会在10年内问世。</p> <p> 纳尼？这么神奇！那我们下面就来看看吧！</p> <p> 一、磁制冷原理介绍：</p> <p> 我们先来看一个视频，详细了解以下磁制冷的基本制冷原理：</p> <p> 再来看看目前国内厂家的磁制冷技术吧：</p> <p> 磁热效应：磁热体在磁场中放热，在磁场去除后吸热</p> <p> 二、磁制冷冰箱原理：</p> <p> 从技术发展的趋势来看，电子制冷冰箱终将取代机械压缩制冷冰箱。</p> <p> 利用磁热效应制成磁制冷冰箱，具有静音工作、制冷效率高、结构简单、节电环保的性能特点。</p> <p> 开发磁制冷冰箱，需要采用的新材料包括磁热材料、绝热材料、热二级管材料、电磁材料。</p> <p> 下面是一组磁制冷冰箱的技术方案示意图：</p> <p> <img alt="美国人研发的磁制冷冰箱，原来长这样！" src="https://www.ktwxx.com/uploads/allimg/200120/000Z62122-0.jpg"></p> <p> 磁制冷冰箱外观示意图</p> <p> <img alt="美国人研发的磁制冷冰箱，原来长这样！" src="https://www.ktwxx.com/uploads/allimg/200120/000ZB039-1.jpg"></p> <p> 磁制冷冰箱结构示意图</p> <p> <img alt="美国人研发的磁制冷冰箱，原来长这样！" src="https://www.ktwxx.com/uploads/allimg/200120/000ZC513-2.jpg"></p> <p> 磁制冷冰箱电子制冷器组件结构示意图</p> <p> 三、磁制冷冰箱结构及工作原理：</p> <p> 磁制冷冰箱技术核心：安装在冰箱顶部的电子制冷器组件。</p> <p> 它由磁热芯体、（围绕在芯体四周的）绝热层体、电磁铁、热二极管模组组成。当通过电磁铁给磁热芯体加上磁场时，磁热芯体放热。</p> <p> 这时，热二极管模组一是导热的，热二极管模组二是绝热的，热量通过模组一导出；</p> <p> 当电磁铁断电，给磁热芯体加上的磁场去除时，磁热芯体吸热制冷。</p> <p> 这时，热二极管模组一是绝热的，热二极管模组二是导热的，这时磁热芯体变成了冰箱的制冷源。这个过程循环往复进行，磁热芯体就能够通过热交换，为磁制冷冰箱源源不断地提供冷气。</p> <p> 四、磁制冷冰箱实际产品：</p> <p> 以下这款冰箱就是由内蒙古包头稀土研究院研发生产的磁制冷冰箱，从外观上看和普通的冰箱并没什么区别，可人家注重的是“内在美”。</p> <p> 这就是它的核心制冷设备，这套设备借助磁制冷材料的磁热效应,通过磁化和去磁过程的反复循环而达到制冷的目的。</p> <p> <img alt="美国人研发的磁制冷冰箱，原来长这样！" src="https://www.ktwxx.com/uploads/allimg/200120/000Z61252-3.jpg"></p> <p> 经试验测试，将117升的磁制冷冷藏柜制冷范围控制在0-10摄氏度之间，最大制冷温差可达到24.5摄氏度，冷藏室温度达到0.1摄氏度，制冷功率接近150瓦左右，已初步具备实用化条件。</p> <p> 与传统压缩制冷相比，磁制冷柜有两大优点，一是节能，二是对环境污染小，几乎不产生污染的气体或者是液体。</p> <br />
