夏日炎炎,一人独居的你是否需要一个实用的小冰箱呢?

材料准备:

1、半导体制冷片(以下简称制冷片),电压12V(可在电子市场买到,视情况选用,最常用的有制冷性饮水机使用的那种,功率不大,如果能买到功率稍大的更好,限于半导体特性,不建议使用100W以上的制冷片)

2、计算机电源

3、CPU散热片及风扇(根据需要选用)

4、泡沫箱(农贸市场上用来装水果的,不要太大,太大了制冷功率跟不上)

5、硅胶

制作过程:

1、首先分清半导体制冷片的热端和冷端,一般的制冷片电源引脚有黑和红两根,分别对应正、负极,再将制冷片加上12V直流电,用手可立即感觉出冷端和热端,分别标记出来。将半导体制冷片两端涂上硅胶,夹在两个散热片中间,热端使用大型的并带由稍大功率风扇的散热片,我使用的就是P4常用的那种,冷端可选用稍小的散热片(是否需要风扇根据自己需要),然后将两个散热片固定住(我用的是双绞线里面的线芯,给两个散热片扎起来)。接通制冷片以及散热风扇电源(计算机电源出来的有12V、5V电源,用12V电就可以了),通电试验,运行正常后继续下一步。

2、在泡沫箱上开孔,孔大小为冷端散热片大小,以便能将散热片放下。安装好散热制冷装置。

3、开机,恭喜你,你的迷你小冰箱制作成功了。

改进分析:

1、冷端的制冷如果仅仅安装了散热片,运时时间长了你就会发现散热片上结霜结冰,而整个泡沫箱下降的温度比较有限(只能低于室温5~8度),解决的办法是使用一个功率较小的风扇装在冷端散热片上,这样下来散热片就不会结霜了,温度可以低于室温14度左右。更好的办法是使用热管或者重新设计冷端风道,可以将冷空气均匀的分布。

2、可以设计制冷的高低档及自动控制,高低档的设计可以结合计算机电源输出的12V和5V电压,高档使用12V电压供电、低挡使用5V电压供电(试验有效);自动控制,可以买一个旧的冰箱使用的温控器装在箱内,用来控制制冷片机散热风扇的电源,以达到自动控制的目的。

试验品温度可以低于室温13度左右。(开机30~50分钟)
