Description

一种降温风扇
技术领域
本专利涉及电风扇，特指一种降温风扇。利用物理和化学原理降温，能有效地降低风扇吹出风流温度，该装置能有效地体验降温和凉爽的效果，无任何污染，适用于炎夏时降温。
背景技术
面对酷暑的夏天，空调成了一种必不可少的降温工具，但空调需要密闭的工作环境，不能适用所有的人群。传统的电风扇作为另外一种降温方法，却不被人们看好。本专利提出了可附于扇叶上的降温装置，使风扇具有风扇和空调的功效，可以适用任何人群的防暑降温之用。
发明内容
本产品在风扇叶片末端装上降温装置，如图1所示，由圆弧壳体、透明挡板和连接螺栓组成，其中圆弧壳体由注塑一次成形，透明挡板用于固定降温装置，连接螺栓用于连接风扇叶片和降温装置。
将降温装置两块圆弧隔板之间的空隙正对风扇叶片，将风扇叶片卡入空隙中，采用连接螺栓连接和固定。
降温装置形成的冷风区和普通风区如图2所示，冷风区形成的环形带向里收缩，内部的普通风区向外膨胀，使得冷风、普通风融合，降低了风的温度。
一种降温风扇，包括风扇叶片，其特征在于：在风扇叶片的侧面顶端装有降温装置，降温装置内装有制冷剂；所述降温装置，包括圆弧壳体和透明挡板，圆弧壳体内设有两块圆弧隔板，在圆弧壳体两侧和圆弧隔板上开有同轴通孔，用于安装连接螺栓；透明挡板上开槽，使得风扇叶片穿过槽伸入到两块圆弧隔板之间的空隙中；风扇叶片上对应的开有连接螺栓的安装通孔。
进一步地，圆弧隔板的弧度、尺寸和应与风扇叶片匹配对应，两块圆弧隔板之间的空隙大小应使得风扇叶片牢固地卡在空隙之间；其中圆弧壳体和圆弧隔板的圆弧半径为50-300mm，两块圆弧隔板之间的间隙为10-50mm。
进一步地，所述制冷剂为多元丙烯酸多元醇的聚合体制冷剂。
进一步地，圆弧壳体、透明挡板和圆弧隔板的材质为S1003的透明PP塑料。
在如图1所示，装置两侧的空间中加入比热容较大的物质，由热力学第三定律，得
△U＝W+Q (1)
式中△U为系统内能的变化量；W为系统对外做功；Q为系统对外吸热或者放热。
由图3可知
W＝0J (2)
由式(1)和(2)得
△U＝Q (3)
由式(3)得出系统内能的增加量等于系统放出的能量，选用冰袋的成分多元丙烯酸多元醇的聚合体制冷剂，以增加系统的吸热时间，达到长时间吸热的效果，在使用后放入冰箱冷冻，可多次使用。
由图3分析，可知图(3)中F⊥V，其中F为运动时的向心力，V为该点时的速度方向，曲线为运动轨迹，所做的功
W1＝0J (4)
降温装置在上升过程中所做的功
W2＝-mgH1 (5)
式中m为降温装置质量；g为重力加速度；H1为降温装置上升高度。
降温装置在下降过程中做的功
W3＝mgH2 (6)
式中H2为降温装置下降高度。
由式(4)、(5)和(6)得
W总＝W1+W2+W3 (7)
＝0J
与传统风扇相比，本专利中风扇没有增加耗能。

图2为风区工作图。
图3为受力情况分析。
具体实施方式
(1)将多元丙烯酸多元醇的聚合体制冷剂加入降温装置，放入冰箱。
(2)取出降温装置，将降温装置两块圆弧隔板之间的空隙正对风扇叶片，将风扇叶片卡入空隙中，用连接螺栓固定降温装置。
(3)旋紧两侧紧固螺栓，使降温装置紧附在风扇叶片上，安装完成后，对透明挡板上的槽用CH-3133型硅酮密封胶进行密封。
(4)打开风扇开关，即可吹出冷风。
