NOVELTY - A solar energy absorber has heat collection tubes (B) that are arranged in parallel, and has upper and lower ends that are closed by end plates (G). Each of the heat collection tubes are coated with a heat absorbing layer. Each heat collection tube has part that is located opposing the heat collection side and contacted with the vacuum heat insulating material.    USE - Solar energy absorber used in water supply pipe for heating water using solar energy.    ADVANTAGE - Offers reduction in weight of the solar energy absorber. Coats heat collection tubes with heat absorbing layer having high heat-absorbing efficiency and heat loss preventing efficiency. Enables to airtightly seal the gaps between the heat collection tubes to restrain air convection. Reduces weight of cover plate and eliminates the need for water storing tank so that weight of the solar energy absorber can reduced. Allows water-flowing section to fully resist pressure of tap water so that deformation can be prevented and the water-flowing section can be directly connected to the water supply pipe. Eliminates the need for ball tap while increasing the pressure of the discharged heated water to that of the tap water since water-flowing section is directly connected to the water supply pipe. Solves low pressure problem of the discharged heated water, preventing flow back of heated water even when the heated water is mixed with the cold tap water, and eliminates the need for a pressurizing pump since water-flowing section is directly connected to the water supply pipe. Prevents molding of black mold so the heated water can be sanitary water since no water storing tank is required. Improves external shape of the solar energy absorber since no water storing tank is required.
