Abstract

一种冷风机，空气流动经过其含水层，并经不同方向的导流而使室内得到新鲜、降温空气；其具有成排直立式蒸发层，并于各蒸发层之间构成风道，在每相邻风道内设导温壳形成冷却风道，由隔离的风道分别导出含(或不含)丰富湿气的冷风。

Description

冷风机
本发明涉及一种冷风机。
现有技术的冷风机是用风扇吹过一含水层，再排出机外。这种结构虽在吹出机外时能微略降温，但含有较重的湿气、水气，并且，排出机外后，水气等随即扩散，因此，这种冷风机极易使室内湿气过多，且仅具有局部降温作用。由于其结构仅能提供一小面积的作用面，无法实现充分蒸发制冷效果。
中国专利申请91100584.6提出一种以空气吸收为能源的蒸发制冷技术，特别是涉及可将气体制冷到湿球或雾点温度以下的集气体制冷、净化、除尘、消音为一体的空调机。但这种空调机是采用膜式蒸发器和间隔式蒸发器，其中膜式蒸发器由配水系统、蒸发膜和框架组成，由蒸发膜使其具有大于自身数十倍的表面积，可将水溶液表面积极大而极薄的展开，使之有足够的动态蒸发表面积，间隔式蒸发器则将上述蒸发膜和导热膜迭合在一起；或是制成管束式，所有这些构件的结构较为复杂，在工艺上难于达到设计要求，以致迄今还未能见到有此类产品问世。
本发明的目的是提供一种冷风机，使其既能提供不富含湿气及水气的空气，又能将导入空气直接逐渐降温。
本发明的目的是这样实现的，即提供一种冷风机，其主要构件有一机壳：设进气口、出气口及排气口，风扇引入空气，并使空气分别由出气口及排气口排出；机壳内设立呈排状直立的蒸发层，并形成蒸发风道及冷却风道；其中蒸发层设置在机壳内水盘上组成框架式结构的上、下固定杆上；工作介质供给装置：由一给水泵提供工作介质给配水管，配水管经给水支管将工作介质均匀地分配至蒸发层上方，并向下均匀流入蒸发层；蒸发层形成若干排纵向排列的分隔空间，在每隔开一个蒸发层的间隔空间设置前后开口、上下左右封闭的导温壳，导温壳内设置与冷却风道同向的鳍片；在蒸发层的尾端(与风扇相对)设置风口板，该风口板上设若干与导温壳尾部接合的开口；导温壳内风道与蒸发层之间未设导温壳风道，经风口板隔离，使空气分别由出气口及排出口排出；蒸发通道上方适当位置设有导向板。
本发明的优点在于能提供一种大面积的蒸发作用面，以形成良好的等温蒸发条件，而得到充分的蒸发，能进行换气，提供不含湿气及水气的空气，将室外的新鲜空气引入室内。
以下结合附图说明本发明的实施例，其中：
图1为本发明冷风机的机壳立体图；
图2为本发明冷风机的机体立体图；
图3为本发明冷风机的部分剖示立体图；
图4为蒸发层及导温壳示意图。
如图1所示，本发明的冷风机包括一机壳1、机壳1上设有一进气口2、在进气口2上设滤网3及一风扇4、机壳1进气口2的相对侧设出气口5、机壳1上方设排气口6及排气罩7，于上述机壳1内装置机体。
机壳1除进气口2、出气口5及排气口6外，呈封闭状态。
图2、3所示为机体立体图，其包括固定框8、固定杆9、蒸发层10、给水泵11、配水管12、给水支管13、均水层14、导温壳15、导向板16、风口板17及水盘18。
在上述固定框8上、下设两排固定杆9，固定框8与固定杆9构成一坚固框体，于固定杆9上设蒸发层10，蒸发层10间形成若干空间，这些空间即为“风道”(后述)。
蒸发层10为耐腐蚀、吸湿性良好、表面蓬松的疏松孔布，呈毯状或单层或数层叠合而成，例如可采用聚丙烯晴纤维(polyacrylic staplefiber)。
在固定杆9上缘蒸发层10上方设有给水支管13及均水层14，以将工作介质均匀地输送至蒸发层10，而直立的蒸发层10则因材料毛细作用及工作介质受地心引力影响而向下流动，并均匀地散布、润湿，流下的工作介质进入水盘18内。
工作介质由给水泵11和水盘18从外部引入，经配水管12由给水支管13细孔(未绘示)渗出，再经均水层14将工作介质散布，使下方蒸发层10被均匀地润湿。
在成排片状蒸发层10之间，每间隔一排内设置导温壳15，该导温壳15为极易导热的材料制成，为前后开口，上、下、左、右都封闭式结构，其左、右两侧与蒸发层10接合，导温壳15构成的空间即为冷却风道B。
在成排片状蒸发层10之间，每一未设导温壳15的间隔，为蒸发风道A，当空气由风扇4引入后，即流向蒸发风道A及冷却风道B，蒸发风道A因空气对蒸发层10上的工作介质等温蒸发，即形成蒸发层10上工作介质蒸发而吸热，而供热来源则是与蒸发层10紧贴的导温壳15，因此，导温壳15即对其内部流经的空气吸热，流经内部的空气因而由前至后逐渐降温。
在促进上述蒸发作用的产生及进行，可于工作介质内加入适量的表面活性剂等；为了增进导温壳15的导温效果，可在导温壳15内设置与冷却风道B同向的鳍片151。
在蒸发层10的尾端(与风扇4相对)设置风口板17，风口板17上设若干开口171，这些开口171与导温壳15尾部接合，使流经冷却风道B内的空气经这些开口171由出气口5排出冷却空气；而在蒸发风道A内的空气则被风口板17阻止，向上而由排气口6排出。
为使蒸发风道A内空气流向稳定，设置导向板16于蒸发风道A上方的适当位置。
上述导向板16可设置于均水层14与蒸发层10上缘之间，或直接装置于机壳1上方而向下将导向板16伸入蒸发风道A内。
前述风口板17，可依使用地区不同而适当地设置开口171，由于蒸发风道A内空气湿度大(温度亦降低)，因此，于干燥地区反而可将之引入，甚至，也可将导温壳15及风口板17都取掉，并将排气口6封闭，成为排出空气湿度大的冷风机。
上述封闭的机壳1，将使机体内的气压略成负压，因而使冷却温度降低，达到更好的制冷效果。
本发明设置直立的蒸发层10，并将成排状蒸发层10分隔及装置导温壳15，不但可在一定的体积里充分有效地提供较大的蒸发作用面，而且巧妙地形成了蒸发风道A及冷却风道B，使流经空气可被迅速冷却及分离而达到较高效率。
如图4所示的蒸发层10及导温壳15，可呈一独立体，即一圆环状蒸发层10，其上下以固定杆9支撑，中间设置导温壳15，使导温壳15内为冷却风道B，而蒸发层10两外侧为蒸发风道A。
上述呈独立体的结构，分别以间隔排列于风扇4后侧以形成蒸发风道A与冷却风道B。
本发明的冷气机，因能提供室外的新鲜空气，因此，更适合于人体的健康。很明显，使用本发明的冷气机，除可将冷却风道B内的空气导出使用外，亦可使用由蒸发风道A排出的空气，用于载培室、养殖室等。
