Summary

A metal foam porous-wall mini-channels heat sink is proposed to solve the heat dissipation problem of linear Fresnel reflection photovoltaic (LFR-PV) system. This paper compares the heat transfer performance of the metal foam porous-wall mini-channels heat sink and the rectangular mini-channels heat sink under different working conditions by method of experimental investigation. The research results show that metal foam porous wall mini-channels heat sink performs larger annular flow area so that the heat transfer performance is better. Compared with rectangular mini-channels of the same size, the heat transfer coefficient is improved by 135% in the same size. Due to the addition of metal foam, the local heat flow distribution in the heat sink changes, and the wall temperature distribution of the heat sink is more uniform.
