Description

螺旋翅片式冷凝器 技术领域
本发明涉及冷凝器技术领域，具体涉及一种螺旋翅片式冷凝器。
背景技术
现有的冷凝器一般采用水冷凝器、纵向混合管束冷凝器、丝管式冷凝器等，现有冷凝器为了将冷却效果发挥的更好，一般都具有散热面积大的特点，这样就产生了一个缺陷，就是体积大，造成成本高，应用受到的很大的限制；而一旦采用体积小的冷凝器，就会存在散热性能差的缺陷。
专利号为200610111866.5的中国发明专利提供了一种螺旋翅片冷凝器，包括螺旋翅片管15，水平固定件20以及垂直固定件30。将螺旋翅片管15首次弯曲成蛇形，以便通过水平固定件20水平布置和固定，然后在首次弯曲的蛇形的纵向方向上进行二次弯曲，并通过垂直固定件30在垂直方向布置和固定。水平固定件20包括固定装置28，固定装置28具有半圆柱形部分和延伸部分26，该半圆柱部分具有与螺旋翅片管15的外径相等的内径，所述延伸部分26在半圆柱形部分的两侧平行延伸。该发明虽然解决了现有技术的缺陷，但在结构上却存在隐患。其水平固定件是直接夹持在螺旋翅片上，在夹紧固定时会对翅片造成严重的损伤，从而导致该冷凝器在制冷效果方面不尽如人意。
发明内容
针对上述技术问题，本发明提供一种解决上述缺陷的螺旋翅片式冷凝器。
实现本发明的技术方案如下：
螺旋翅片式冷凝器，包括冷凝管和翅片，所述翅片螺旋式地缠绕在冷凝管的表面上，冷凝管经过多次迂回、弯曲形成立方体结构；还包括贴合在翅片上并夹持固定在冷凝管上的固定支架。
进一步地，所述翅片与散热管连接的内侧为波浪式结构，外侧为平滑式结 构。
进一步地，所述固定支架包括安装板以及连接在安装板侧面的夹紧机构，所述夹紧机构由多个均布在安装板上的卡紧单元构成，相邻两个卡紧单元之间设有间隙，而每个卡紧单元由两个卡片构成，两个卡片之间设有与冷凝管相适应的卡槽。
进一步地，所述卡槽底部设有至少一个调整槽，该调整槽延伸至安装板上。
进一步地，所述夹紧机构设置有一个或两个。
进一步地，所述固定支架包括安装板以及分别在两侧设有多个卡片，两侧上的卡片交错设置，该安装板的两侧经过两次折弯后形成T形结构，两侧的卡片之间形成与冷凝管相适应的卡槽。
进一步地，所述一次折弯为180°，二次折弯为90°。
进一步地，所述卡片所在的平面低于安装板所在的平面。
进一步地，所述卡片的端部的内侧的设有内斜面，外侧设有外斜面，内斜面和外斜面之间为直面或向外凸起的弧面。
进一步地，所述外斜面的倾斜角度大于内斜面的倾斜角度。
采用了上述方案，本发明的冷凝器为“回”字形立方体结构，结构的体积大大减小，但紧凑牢固，同时降低成本；该结构内部具有足够的通风空间和散热空间，保证了冷凝管的热交换效果，提高了其制冷效果和制冷量；固定支架一方面能够起到对冷凝器结构固定的作用，保证管子之间的固定间距，防止受到挤压冷凝器发生变形，另一方面可以用来保护翅片，防止在安装固定支架时使其周边的翅片变形或相互交错在一起，从而影响到冷凝器的制冷效果。
本发明中的固定支架改变了以往夹持在翅片的方式，其直接夹持在冷凝管的表面上，从而达到紧固冷凝管的作用，该形式可靠稳定，而且不作用于翅片 就不会直接或间接伤害到翅片。要知道，翅片是为了增大冷凝管的换热面积，从而提高其换热效率。若翅片变形或相互缠绕，该冷凝器的制冷效果就会大打折扣，造成局部热交换效果差，气流变得紊乱，热量无法散去，严重时冷凝器无法进行制冷工作。本发明的方式，即使冷凝器受到外力而被挤压，其作用力只会在固定支架和冷凝管上，而固定支架承受大部分外力，这样翅片的结构和形状就得到保护，冷您管本身也不会变形，冷凝器的制冷效果就得到了保证。

具体实施方式
下面结合附图和具体实施例对本发明进一步说明。
实施例1，如图1至图6，螺旋翅片式冷凝器，包括冷凝管1和翅片2，所述翅片2螺旋式地缠绕在冷凝管1的表面上，翅片2与散热管1连接的内侧为波浪式结构21，外侧为平滑式结构22，内侧采用波浪式结构连接一方面连接牢 固，不易滑动，在装配的过程中能够分散来自外界的作用力，不易损坏，另一方面是用于能够对热量进行导向、对热气流进行导流，快速散热；外侧的平滑式结构能够保证翅片在散热时形成的散热方向是发散均匀的整体线性散热，如果继续是波浪式结构，就会导致散热片散热并非线性发散，散热辐射有交叉和重叠，热辐射波在重叠时会相互影响，造成一定阻力，从而影响到其制冷效果。
冷凝管经过多次迂回、弯曲形成立方体结构，这样该冷凝器的体积就大大减小，占用空间也变小，但是却能保证良好的制冷效果，具有广泛的应用前景。
还包括贴合在翅片2上并夹持固定在冷凝管1上的固定支架3，固定支架3包括安装板31以及连接在安装板31侧面的夹紧机构32，夹紧机构32与安装板31垂直连接，这里的夹紧机构可以有一个(图6)，也可以有两个(图5)，当夹紧机构设有一个时，其连接在安装板的任意一侧面，而当夹紧机构设有两个时，则其对称地连接在安装的两个侧面上，夹紧机构的设置可根据冷凝器具体的结构和大小做相应的调整，当然，为了便于制作，通常安装板与夹紧机构是一体成型的，后期在通过设备或人工折弯即可制成。
夹紧机构32由多个均布在安装板31上的卡紧单元321构成，相邻两个卡紧单元之间设有间隙322，这里的间隙大小与冷凝器管之间的间距大小一致，而每个卡紧单元321由两个卡片323构成，两个卡片之间设有与冷凝管相适应的卡槽324，在固定支架安装在冷凝上时，将卡槽对准冷凝管并插到底部，一般来说卡片的长度相对较长，其长度至少有两个冷凝管的外径之和，当冷凝管卡在卡槽内后，再用模具将卡片横向压紧，即将两个卡片端部的距离收缩，这样一来就可以牢牢地将冷凝管卡住。
实施例2，如图7，当然，卡片为刚性结构，为了防止其发生断裂，以及能 够顺利地将卡片收缩，在卡槽324底部设有三个调整槽325，该调整槽延伸至安装板上。
实施例3，如图8-图11，固定支架3包括安装板31以及分别在两侧设有多个卡片323，两侧上的卡片交错设置，该安装板的两侧经过两次折弯后形成T形结构，一般来说第一次在A处折弯为180°，第二次在B处折弯为90°，当然折弯顺序也可以反过来，两侧的卡片323之间形成与冷凝管相适应的卡槽324，而安装板的端部成为限位部，保证冷凝管卡在卡槽内，卡片所在的平面低于安装板所在的平面，这样在折弯成型后所有卡片都可在同一平面上，可以有效地对冷凝管进行夹持固定，而安装板可盖住更多的翅片，在安装固定支架或冷凝器时防止翅片变形。
如图12，卡片323的端部的内侧的设有内斜面3231，这样卡片形成卡槽的端部口径变大，更容易对准冷凝管，便于冷凝管插入插槽内，防止冷凝管还没插入插槽内就已经使卡片折弯变形，影响其使用；外侧设有外斜面3232，这样能够去除卡片尖锐的棱角，因为在收紧卡片时是用到相应的模具，而棱角会对模具以及操作人员造成损伤，所以该外斜面的设置是为了保证模具能够长期使用，降低成本，以及保护操作人员的安全；内斜面和外斜面之间为直面或向外凸起的弧面3233，其目的是为了防止形成尖锐的棱角，外斜面的倾斜角度大于内斜面的倾斜角度，一般地的外斜面与水平线的夹角α为60°，内斜面与水平线的夹角β为45°。
当然，为了能够保证固定支架与冷凝器固定连接，可在固定支架上开设有多个固定孔(图中未标记)，通过在固定孔内拧入螺钉即可将其固定，结构简单，方便拆卸维护。
本发明采用的固定支架还具有以下优势：
a.固定支架直接与冷凝管相连，可作为吸热散热媒介，更进一步地增大了换热面积，即固定支架直接进行换热，换热效果较以往的方式更上一层楼。
b.结构简单，制作方便，生产成本低，减少了安装时间，提高了工作效率。
c.降低冷凝管共振频率，从而减少冷凝器的振动，防止因为振动而造成其与冰箱连接处松动，以至于造成不必要的损失。
