Description

热泵机组换热器
技术领域
本发明属于热泵机组部件技术领域,特别涉及一种热泵机组换热器。
背景技术
换热器是空气源热泵机组内一个重要的部件,空气经过换热器,空气上的热量被翅片吸收,翅片的热量被吸热管内的制剂吸收,翅片温度降低,水汽会在翅片表面冷凝形成水珠,从而影响制剂从空气中吸收热量。
中国专利CN2731386,专利名称空气源热泵室外宽窄片距翅片式换热器,公开了一种空气源热泵室外宽窄片距翅片式换热器,它涉及以空气为低位热源的冷热水机组、单元式热泵型空调机、屋顶式热泵型空调机组、热泵型房间空调器等的室外翅片式换热器的结构。本发明的换热器由换热管、翅片组成,翅片固定在换热管的外壁上,换热器空气出口一侧的翅片的间距小于换热器空气进口一侧的翅片的间距。虽然该发明提高了换热器的工作效率,但是翅片上仍然容易形成水珠。
发明内容
本发明的目的是为了克服现有技术容易形成水珠的缺点,提出一种热泵机组换热器,不容易形成水珠。
为了实现上述目的,本发明采用以下技术方案:
一种热泵机组换热器,包括壳体、位于壳体上侧的出风口、位于壳体上的进风口、位于进风口上的吸热组板,所述吸热组板包括若干相互平行呈阵列布置的翅片、若干吸热管,所述吸热管呈迂回结构并垂直穿过翅片,所述吸热管沿着翅片的轴向均匀布置,所述翅片的材质为亲水铝箔。亲水铝箔避免水珠的形成,迂回结构增加吸热管的长度,以及二氧化碳吸收热量的时间,多个吸热管的设计增加吸热效率。
作为优选,吸热管的材质为纯铜。吸热管采用纯铜,纯铜具有很好的热传导性,能很好的帮助二氧化碳吸收空气的热量。
作为优选,吸热组板的数量为两个,所述吸热组板位于壳体左右两侧,两个吸热组板之间呈倒八字形摆放。吸热组板对称布置,出风口设有风机,风机运行的时候,两个吸热组板进风相等,倒八字布置一定程度可以增大吸热组板底端的进风量,吸热效率高。
作为优选,壳体一侧设有呈U字形的主管,所述主管位于吸热组板之间,所述主管包括左右两根竖段、位于竖段之间的横段,所述横段中间设有接口,左右两侧的吸热组板的吸热管的一端连接在对应的竖段上。结构简单。
作为优选,吸热管两端均位于壳体同一侧。结构简单。
作为优选,出风口的数量为两个。采用双风机的设计,空气流动快,吸热效率高。
作为优选,翅片的厚度从上往下逐渐变薄。风机运行时,壳体内的气压会降低,由于壳体内部上侧距离风机距离比较近,因此壳体内从上到下气压逐渐增大,吸热组板两侧的压差从上到下逐渐减小,本发明中,翅片的厚度从上到下逐渐减小,因此翅片的间距从上到下逐渐增大,从而使得空气在吸热组板上下两端的进气速度更加均匀,吸热组板的吸热效率大大增加。
本发明的有益效果是:本发明不容易形成水珠;吸热效率高,吸热组板上下进风速度均匀,吸热组板利用率高。
附图说明
图1为本发明的示意图;
图2为本发明的侧视图。
图中:壳体1、出风口2、翅片4、吸热管5、主管6、竖段7、横段8、接口9。
具体实施方式
下面结合附图和具体实施方式对本发明进一步详细阐述:
实施例:
参见图1至图2,一种热泵机组换热器,包括壳体1、两个位于壳体1上侧的出风口2、位于壳体1上的进风口、位于进风口上的吸热组板,吸热组板的数量为两个,所述吸热组板位于壳体1左右两侧,两个吸热组板之间呈倒八字形摆放;所述吸热组板包括若干相互平行呈阵列布置的翅片4、若干吸热管5,吸热管5的材质为纯铜;翅片4的厚度从上往下逐渐变薄;所述吸热管5呈迂回结构并垂直穿过翅片4,所述吸热管5沿着翅片4的轴向均匀布置,所述翅片4的材质为亲水铝箔;壳体1一侧设有呈U字形的主管6,所述主管6位于吸热组板之间,所述主管6包括左右两根竖段7、位于竖段7之间的横段8,所述横段8中间设有接口9,左右两侧的吸热组板的吸热管5的一端连接在对应的竖段7上;吸热管5两端均位于壳体1同一侧。
实施例原理:
本发明用于空气源热泵机组,在吸热管内流动二氧化碳,二氧化碳从接口9进入,然后从吸热管另一端流出,吸热管吸收空气中的热能,翅片4增加了吸热面积,出风口2布置风机,风机运行,空气从翅片之间流过,将热量传递给翅片然后传递给吸热管内的二氧化碳,翅片上的热量会被二氧化碳吸收,因此翅片上温度较低,由于翅片采用亲水铝箔,可以很好的避免形成水珠,同时,吸热管采用纯铜,纯铜具有很好的热传导性,能很好的帮助二氧化碳吸收空气的热量,风机运行时,壳体内的气压会降低,由于壳体1内部上侧距离风机距离比较近,因此壳体1内从上到下气压逐渐增大,吸热组板两侧的压差从上到下逐渐减小,本发明中,翅片的厚度从上到下逐渐减小,因此翅片的间距从上到下逐渐增大,从而使得空气在吸热组板上下两端的进气速度更加均匀,吸热组板的吸热效率大大增加。
