Abstract:
1. A heat collector comprising two opposite surfaces and one or more surrounding sides; wherein a matrix of the heat collector is made from a thermally conductive material; and a plurality of adiabatic pores are within the matrix; wherein the relative concentration distribution of the adiabatic pores progressively increases from one of the opposite surfaces to the other opposite surface, and progressively decreases from the surrounding sides to the center of the heat collector, the amount of adiabatic pores progressively increases from the one of the opposite surfaces to the other opposite surface, the opposite surface having the smaller relative concentration of the adiabatic pores is a heat absorption surface, and the relative concentration of the adiabatic pores at the heat absorption surface is 0%.
