The invention discloses a forced circulating and cooling system for solar light condensing power generation medium with light condensing magnification exceeding thousand-hold. The system comprises a power generation chip, wherein the power generation chip is provided with a positive outside wire and a negative outside wire. The key points of the invention is that the power generation chip is connected with a heat dissipating platform and a light condensing radiator to form a medium cooling and circulating system; high-transmittance heat-protecting glass is arranged above the light condensing radiator; the four walls of the light-passing port of the light condensing radiator are provided with a high reflectorized material; and the power generation chip and the light condensing radiator areprovided with heat-protecting glass. When the light condensing magnification is higher, the invention enables the power generation chip to keep lower temperature by means of multiple heat dissipation, i.e. the magnification of lenses reaches above thousand-hold; and when the temperature is higher than 1000 DEG C, a composite heat abstractor carries out multi heat dissipation and cooling, thus thefinal temperature of battery chips can be controlled to be within 100 DEG C for carrying out normal power generation, the contradictories between large solar light condensing magnification and high chip temperature, short service life and influenced power generation effect as well as technical difficulties are solved, and the application fields of solar batteries are greatly widened.
