One kind w type concentrating solar absorber

The present invention provides a W-type concentrating solar absorber. The absorber comprising: a housing, and a heat-absorbing chamber attached to the sidewall of the heat absorption chamber of heat absorption coil. Wherein the bottom portion of the heat absorption chamber with a heat sink reflecting means for irradiating the heat-absorbing chamber to the bottom of uniformly reflecting sunlight to the side wall of the heat absorption chamber. Thus, both to ensure the utilization of solar energy, but also to avoid the heat absorption chamber is located at the bottom of the excessive heat absorbing coil due to heat and burned.
