Abstract

Abstract Two box-type solar cooker (BTSC) prototypes were tested to examine thermal performance under identical conditions. The first box solar cooker used an absorber plate fabricated from copper, and the second box solar cooker used 40 pores per inch (PPI) of copper foam sheets. Many experiments on solar cookers were carried out in September 2022 in Baghdad, Iraq, where the solar cookers were directed to the south and situated at latitude 33.3°N and longitude 44.4°E. In the experimental testing, copper metal foam 40 PPI is used as a heat absorber plate at various absorber plate heights (1, 3, 5, and 7 cm). The results showed that the solar cooker with a 40 PPI copper foam absorber experienced a stagnation temperature of roughly 17° higher compared to a BTSC with a standard absorber. A copper foam 40 PPI absorber plate can reduce cooking time in a BTSC by as much as 23% compared to a standard flat absorber plate. The percentage of increase in the solar cooker’s internal temperature with an increase in absorber plate height from 1 to 7 cm for 40 PPI copper foam absorber plate is approximately 16.1%. The acceptable range for the equation of cooking power indicates that the cooker can be relied upon for consistently cooking food and boiling water.

40-PPI铜泡沫层高度对太阳灶性能的影响

摘要对两台箱式太阳能炊具(BTSC)样机进行了相同条件下的热性能测试。第一个箱式太阳能炊具使用了由铜制成的吸收板，第二个箱式太阳能炊具使用了每英寸40个孔(PPI)的铜泡沫板。2022年9月，在伊拉克巴格达进行了许多关于太阳能炊具的实验，在那里，太阳能炊具朝向南方，位于北纬33.3°和东经44.4°。在实验测试中，采用40ppi的铜金属泡沫作为吸热板，吸热板高度分别为1、3、5、7cm。结果表明，与带有标准吸收体的BTSC相比，带有40 PPI铜泡沫吸收体的太阳灶经历了大约17°的停滞温度。与标准的扁平吸收板相比，泡沫铜40 PPI吸收板可以减少BTSC中的烹饪时间多达23%。对于40ppi铜泡沫吸收板，吸收板高度从1 cm增加到7 cm时，太阳灶内部温度升高的百分比约为16.1%。烹饪功率方程的可接受范围表明，该炊具可以可靠地烹饪食物和烧开水。
