Description

换热组件和换热设备 技术领域
本发明涉及换热技术领域，具体而言，涉及一种换热组件和换热设备。
背景技术
现有技术中的换热器与风机配合布置间距往往未考虑其间距布置所带来的阻力影响，由于间距布置不当引起的进风阻力增加，对整机气动效率、风量与噪音等方面均会带来不利影响，因此有必要对其间距布局进行优化。
由此可知，现有技术中的换热器与风机之间存在间距布局不当引起的进风阻力增加导致整机气动效率降低与噪音升高的问题。
发明内容
本发明的主要目的在于提供一种换热组件和换热设备，以解决现有技术中的换热器-风机之间的间距布局不当引起的进风阻力增加的问题。
为了实现上述目的，根据本发明的一个方面，提供了一种换热组件，包括：换热器；风机，换热器与风机间隔设置并位于风机的来风方向或出风方向上，风机具有风口，且风机朝向换热器的风口与换热器之间的最短距离H与风机的叶轮直径D应满足
Figure PCTCN2018075741-appb-000001
进一步地，风机的风口在换热器上的投影位于换热器的边缘之内。
进一步地，换热器在平行于风口的参考平面内的投影面积S0大于风机的风口在参考平面内的投影面积SP。
进一步地，换热器的出风面积S1大于风机的风口的进风面积S2。
进一步地，出风面积S1与风机的风口的进风面积S2满足
Figure PCTCN2018075741-appb-000002
进一步地，换热器是弧形板状结构或多个板状段顺次连接而成的折弯形板状结构。
进一步地，换热器是多个板状段顺次连接而成的折弯形板状结构，且朝向风口的板段相对于风口倾斜设置。
进一步地，换热器围成换热区域，风机的风口位于换热区域内。
进一步地，换热器是平板状结构，且换热器相对于风口平行设置或倾斜设置。
进一步地，换热器是V形换热器、W形换热器、波浪形换热器中的至少一种。
根据本发明的另一方面，提供了一种换热设备，包括上述的换热组件。
进一步地，换热设备是空调器。
应用本发明的技术方案，换热组件包括换热器和风机，换热器与风机间隔设置并位于风机的来风方向或出风方向上，风机具有风口，且风机朝向换热器的风口与换热器之间的最短距离H与风机的叶轮直径D应满足
Figure PCTCN2018075741-appb-000003
当换热组件工作时，风机启动，在负压的作用下，风由风机吹向换热器或首先经过换热器进行换热处理，经过换热处理后的风由风机的风口流经风机后吹出。由于进风阻力随换热器与风机间距增加呈现先大幅衰减后逐渐趋于稳定的变化趋势，因而当换热器与风机的风口之间的最短距离H与风机的叶轮直径D应满足
Figure PCTCN2018075741-appb-000004
时，可以保证进风阻力较小且趋于稳定，进而有效地避免了因进风阻力增加导致整机气动效率降低与噪音升高。

优选地，换热设备是空调器。
如图1至图8所示，换热组件包括换热器10和风机20，换热器10与风机20间隔设置并位于风机20的来风方向或出风方向上，风机20具有风口21，且风机20朝向换热器10的风口21与换热器10之间的最短距离H与风机20的叶轮直径D应满足

具体地，当换热组件工作时，风机20启动，在负压的作用下，风由风机20吹向换热器10，或首先经过换热器10进行换热处理，经过换热处理后的风由风机20的风口21流经风机20后吹出。由于进风阻力ΔP(Pa)随换热器10与风机20间距增加呈现先大幅衰减后逐渐趋于稳定的变化趋势，因而当换热器10与风机20的风口21之间的最短距离H与风机20的叶轮直径D应满足
Figure PCTCN2018075741-appb-000006
时，可以保证进风阻力较小且趋于稳定，进而有效地避免了因进风阻力增加导致整机气动效率降低与噪音升高。
需要说明的是，当风机20的进风口朝向换热器10时，此时，风先经过换热器10再流入风机，此时风口21是进风口。而当风机20的出风口朝向换热器10时，此时，风先经过风机20再吹向换热器10，此时风口21是出风口。
下面将以风口21是进风口为例，进行阐述。
为了保证换热组件的换热效果和整机的启动效率。本发明中的风机20的风口21在换热器10上的投影位于换热器10的边缘之内。这样，可以保证由风口21进入风机20内的风全部都经过换热器10的换热，从而保证换热组件的换热效率。
可选地，风机20是贯流风机或离心风机。
下面将根据换热器10的具体结构不同，分为四个实施例进行说明。
实施例一
如图1至图5所示，在本实施例中，换热器10是由多个板状段顺次连接而成的折弯形板状结构，且换热器10的出风面积S1大于风机20的风口21的进风面积S2。
需要说明的是，换热器10的出风面积S1是指风流经换热器10吹出的整体面积，在图2中，S1指的是换热器10的出风侧的整个表面积。
具体的，换热器10由三个板状段顺次连接而成以形成U形换热器。且位于中间的板段正对风机20的风口21设置。当然，在其他的实施例中，也可以考虑将中间的板段倾斜于风口21设置，例如实施例五。
可选地，出口部12的出风面积S1与风机20的风口21的进风面积S2满足
Figure PCTCN2018075741-appb-000007
需要说明的是，应合理控制S1/S2的比值。避免S1/S2的值过小或过大，当S1/S2的值过小时，换热器10的尺寸无法满足换热需求；当S1/S2的值过大时，会产生较大的进风阻力ΔP。
如图1所示，换热器10在平行于风口21的参考平面30内的投影面积S0大于风机20的风口21在参考平面30内的投影面积SP。通过上述的设置，可以使得换热器10的面积足够大，有利于保证由风口21进入风机20内的风全部都经过换热器10的换热，从而保证换热组件的换热效率。
具体的，在图1至图4中，由于换热器10的朝向风口21的部分平行于风口21设置，因而该部分、参考平面30以及风口21所在的平面都是相互平行的。这样，就使得上述的投影面积就是对应结构的结构面积。
如图1至图3所示，换热器10围成换热区域11，风机20的风口21位于换热区域11内。由于风口21位于换热区域11内，因而经换热器10换热后的风能够顺利进入风机20内，从而保证换热组件的换热效率。
如图5所示，在该实施例中，随着换热器10与风机20的风口21之间的最短距离H与风机20的叶轮直径D比值的变化，换热组件的进风阻力ΔP也随之变化，且具体的变化关系是：进风阻力ΔP(Pa)随换热器10与风机20间距增加呈现先大幅衰减后逐渐趋于稳定的变化趋势。
由此可知，除了S1/S2的比值会影响进风阻力ΔP以外，换热器10与风机20的风口21之间的最短距离H与风机20的叶轮直径D的比值同样对进风阻力ΔP具有较大的影响。
实施例二
与实施例一的区别在于，换热器10的结构不同。
在该实施例中，如图6所示，换热器10是弧形板状结构的。
同样的，换热器10可以围成换热区域11。风机20的风口21位于换热区域11内。当然，风口21也可以不在换热区域11内。
与图1的实施例相比，换热器10在参考平面30内的投影面积S0不变，风机20的风口21在参考平面30内的投影面积SP也与图1中保持一致。
相比于实施例一中的换热器10，该实施例中的换热器10的换热面积更大，单位面积内的换热效果更好。
实施例三
与实施例一的区别在于，换热器10的结构不同。
在该实施例中，如图7所示，换热器10是平板状结构，且换热器10相对于风口21平行设置。
在该实施例中，换热器10无法围成换热区域11，仅是单纯的设置在风机20的进风侧。
这样，在该实施例中，换热器10的进风面积与出风面积是相等的。为了保证和其他实施例中的一致性，在图7中，仍然沿用了S1，以表示换热器10的出风面积。
与图1的实施例相比，换热器10在参考平面30内的投影面积S0不变，风机20的风口21在参考平面30内的投影面积SP也与图1中保持一致。
相比于实施例一中的换热器10，该实施例中的换热器10的结构更加简单。
实施例四
与实施例三的区别在于，换热器10的结构不同。
在该实施例中，如图8所示，换热器10是平板状结构，且换热器10相对于风口21倾斜设置。
在该实施例中，换热器10无法围成换热区域11，仅是单纯的设置在风机20的进风侧。
这样，在该实施例中，换热器10的进风面积与出风面积是相等的。为了保证和其他实施例中的一致性，在图8中，仍然沿用了S1，以表示换热器10的出风面积。
与图1的实施例相比，换热器10在参考平面30内的投影面积S0小于换热器10本身的进风面积。而风机20的风口21在参考平面30内的投影面积SP也与图1中保持一致。。
相比于实施例一中的换热器10，该实施例中的换热器10的结构更加简单。
实施例五
与实施例一的区别在于，朝向风口21的板状段相对于风口21是倾斜设置的。其具体的设置形式可以参考图8中的描述。
相比于实施例一中的换热器10，该实施例中的换热器10的换热面积更大，单位面积内的换热效果更好。
当然，除了图示中的换热器10以外，V形换热器、W形换热器、波浪形换热器等各类不同形状的换热器同样适用以上的布局形式。
显然，上述所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
