Description

一种太阳能热水器集热板
技术领域
本实用新型涉及太阳能热水器,尤其是一种太阳能热水器集热板。
背景技术
如图1所示现有的一种太阳能热水器集热板包括一个由上下两片金属板压制而成的平板本体,本体上设有纵向排列的复数个平行排水管腔和横向排列的上集管腔和下集管腔,上集管腔连接出水管,下集管腔通过一减压管腔连接进水管,由于有复数个排水管腔对减压管腔内的水流进行分流,故减压管腔需比排水管腔尺寸要大,而本体都为铝吹塑制成,尺寸做大后管腔壁需承受的水流冲击力增加,减压管腔壁经常出现变形、渗漏现象。
发明内容
本实用新型的目的是为了解决上述现有技术的不足而提供一种带两减压管腔的太阳能热水器集热板。
为了达到上述目的,本实用新型所设计的一种太阳能热水器集热板,包括一个具有进水管和出水管的本体,本体顶部设有上集管腔,底部设有下集管腔,中间设有排水管腔,本体上靠近进水管一侧设有与排水管腔平行的减压管腔,所述减压管腔的两端分别连接进水管和下集管腔,其特征是所述的减压管腔有两个,呈并列设置,所述两减压管腔的上管腔口汇合连接进水管,所述两减压管腔的下管腔口汇合连接下集管腔。此结构通过两并列设置的减压管腔来输送待加热的水,在保证一定总体流量的情况下,对进水管流出的水流进行分流,可将减压管腔内径做小,管腔壁收到的水流压力减小,有效降低了减压管腔壁变形、渗漏现象的发生。
作为上述结构的进一步完善和补充,本实用新型还包含以下附加技术特征或这些特征的任意组合:
所述的进水管和出水管设于本体顶部两端,各排水管腔内的水流汇入上集官腔后,汇入的水流向出水管运动时均沿同一方向,减少水流间的相互干扰,流通顺畅。
所述的两减压管腔尺寸相同,分流分压均衡,两减压管腔可共用一管腔壁,使得共用的管腔壁内外受力相当;所述的减压管腔和排水管腔的横截面均为曲面,热交换面积大,热交换效率高。
所述的减压管腔的长内径小于或等于排水管腔的长内径,减压管腔的内径过大,管腔壁受到的水流冲击力过大,管腔壁易引起变形和渗漏。
所述的减压管腔长内径大于或等于排水管腔长内径的二分之一,减压管腔的内径过小,则排水管腔内水流过小,被加热的水量少。
所述的下集管腔靠减压管腔的管腔口设有导流板,所述的导流板的下游段向上倾斜,导流板将水流导向靠减压管腔侧的排水管腔,使各排水管腔的水流均衡,使水流充分吸收集热板上的热量。
所述的导流板为片状的直板,表面光滑,导流效果好。
所述的导流板水平倾角为10度-25度,此角度范围内,导流效果好,可根据水流流速来选取最佳倾斜角度。
本实用新型通过两并列设置的减压管腔来输送待加热的水,在保证一定总体流量的情况下,对进水管流出的水流进行分流,可将减压管腔内径做小,管腔壁收到的水流压力减小,有效降低了减压管腔壁变形、渗漏现象的发生。
