تأثير إضافة الزعانف في كمية الطاقة المخزنة في نظام التخزين الحراري الكامن

الملخص EN

The right choice of the dimensions of the heat storage tank is very important in determining the amount of stored thermal power and the speed of charging and discharging that stored energy.

In this paper, we have compared two tanks with the same dimensions (10*10*10 cm), one with three copper fins spaced 3.3 cm from each other and another without any fines.

The length of the copper fins is 50 cm with a thickness of 1 mm.

The phase change material used in this experiment is regular water.

The cooling surface (heat sink reservoir) was at a temperature of (- 1 8 °C).

Experimental results showed that adding copper fins into latent heat thermal storage system produce an increase in the interface speed by 46% and an increase of energy stored by 54% for a period of 24 hours of continuous operation.
