Description

一种节省电冰箱/空调器能耗的方法 技术领域
本发明涉及一种节能方法，具体说，是涉及一种节省电冰箱/空调器能耗的方法。
背景技术
随着电冰箱/空调器的数量越来越多，对能源的消耗越来越大，关于电冰箱/空调器的节能技术显得越来越重要，关于如何节省电冰箱/空调器能耗的技术成为当前研究热点。虽然中国专利局公告的专利申请号为201610176192.0、发明名称《一种节能空调雾化器》的发明中公开了一种节省电冰箱/空调器的发明，该发明采用将冷凝水进行雾化喷出对散热器进行降温，以节省能源，但该发明所采用的装置结构复杂，生产成本高，并且只能利用电冰箱/空调器自身产生的冷凝水，节能效果有限。因此，现在仍需节能效率高、生产成本低、结构简单的有关节省电冰箱/空调器能耗的节能技术。
发明内容
针对现有技术所存在的上述问题和需求，本发明的目的在于提供一种节能效率高、工艺简单、成本低的节省电冰箱/空调器能耗的方法。
为实现上述目的，本发明采用如下技术方案：
一种节省电冰箱/空调器能耗的方法，所述电冰箱/空调器包括散热器，所述散热器包括散热片或/和散热管，所述方法是将水通过自身重力引入散热片或/和散热管的表面进行冷却散热，从而节省能耗。
现在的电冰箱/空调器的散热方式是通过热量与空气的交换，因空气的比重只有水的八百分之一左右，并且水的气化热是在常温下所有液体中最大的，因此将水直接引入到电冰箱/空调器的散热器的散热片或/和散热管的表面上后，可直接进行降温。水在吸收了散热片或/和散热管的表面上的热能之后马上蒸发，将热能带走，提高散热效率，而节省能耗。水通过自身的重力引入，可以避免现有发明采用水泵进行喷洒或超声波雾化等方法的缺陷，因为电冰箱/空调器工作的时间非常长，长时间工作容易引起水泵或超声波设备在使用中的故障，同时，水泵或超声波设备在使用中会产生噪声影响使用环境，并且增加额外能耗。
作为优选方案，所述水通过自身重力从散热器的上方引入散热片或/和散热管的表面。 事实上，只要将水引入到散热片或/和散热管的表面，就能达到节能效果，但如果从上方引入，不仅可以增加与散热片或/和散热管的表面接触面积，而且可以同时对散热片或/和散热管的表面进行冲洗，将粘接在散热片或/和散热管表面的灰尘进行清洁，以避免表面污垢对散热效果的影响。
作为优选方案，在所述散热器的上方设有水槽，水槽里的水通过自身重力从散热器的上方引入散热片或/和散热管的表面。所述水的来源有多种，如雨水，收集后放入水槽可以方便使用。
作为优选方案，在引入水与散热器之间设有布水器，以保证水均匀引入散热片或/和散热管的表面。如果水直接引入到散热片或/和散热管的表面，会产生不均匀现象，而不均匀就会使部分散热片或/和散热管的表面没有水，这样就会降低节能效果。通过布水器就能均匀地将水引入到散热片或/和散热管的表面，达到最好的散热效果。所述的布水器是能将引入的水均匀地洒在散热片或/和散热管上的一种装置，一般采用多孔状材料如海绵、纱布、纺织纤维布或团，使水先引入到所述布水器上，然后由布水器均匀地流入到散热片或/和管上，可达到充分换热效果，避免水直接从上面冲下造成局部换热不均匀的现象。
作为进一步优选方案，所述水为软化水。虽然水的降温散热效果好，但一般的水(如自来水)中因含有大量的钙镁离子和氯离子，水蒸发后钙镁离子就会在散热片或/和散热管上沉积，形成一层水垢，而水垢的导热效果差，会阻碍热量的散发，同时氯离子会使散热片或/和散热管产生腐蚀。
作为进一步优选方案，所述软化水为外界提供或由电冰箱/空调器自身产生的冷凝水。由电冰箱/空调器自身产生的冷凝水是从空气中冷凝产生，不含钙镁离子，由外界提供的软化水为雨水或由水处理器产生。雨水也是从空气中凝结产生的，同样不含钙镁离子。并且，由于冷凝水本身的温度低，可以更好地提高散热效果。此处的水处理器是指软化水处理器，一般是离子交换树脂水处理器，采用离子交换树脂将水中的钙镁离子交换成钠离子，变成软化水，当树脂达到饱和后，可进行再生处理重复使用。
作为进一步优选方案，所述水处理器是设置在散热器上方的内设有软化树脂的水槽。这种结构简单方便，制造成本低。
作为进一步优选方案，对所述散热片或/和散热管的表面进行物理或/和化学处理，使散热片或/和散热管的表面积增大，以进一步增加散热片或/和散热管的散热性能。因为散热片或/和散热管的表面积越大，热交换的效果越好。通常物理方法是对表面进行打磨、喷 砂、毛化处理、超声波处理，使表面粗糙化。
作为进一步优选方案，在电冰箱的散热管上包覆具有吸水功能的多孔材料。现在的电冰箱大部分是采用散热管来进行冷却，在散热管上包覆具有吸水功能的多孔材料如海绵、聚丙烯纤维等，可以保持水在散热管表面的充分接触的面积，从而提高散热效果。
作为进一步优选方案，在所述水引入散热片或/和散热管前过滤处理。因为水从管道中引入时会带来部分杂质，使用时间一长，会慢慢堵塞布水器。如雨水在收集过程中会带入灰尘，又如树脂在长期使用过程中会产生破裂。
与现有技术相比，本发明具有如下有益效果：
本发明通过将水借助自身重力引入散热片或/和散热管的表面以实现对电冰箱/空调器的散热器进行冷却散热，无需借助外界动力，真正实现了能耗节约(相对于现有技术，至少可节能20％)，尤其是，本发明方法可利用电冰箱/空调器自身产生的冷凝水、还有外界的雨水，也不会产生额外的噪音影响电冰箱/空调器的使用环境，并且应用简单，无需改变现有电冰箱/空调器的散热器结构，可广泛推广应用。
