PROBLEM TO BE SOLVED: To solve a problem that, since most of present heat collectors employ vacuum glass tube heat collectors, a phenomenon such as a secondary flow, a short-circuited flow, and an eddy flow may occur when the present heat collector employs a natural fine cirlulation system, and furthermore, there arises such a defect that the connection of a connection tube and a heat collection tube may not allow the present heat collector to receive pressure when the present heat collector is sealed by using a simple silica-gel sealing washer. SOLUTION: Intermittent forcing circulation by a circulating pump is applied, a flow channel blind flange and a water injection tube are additionally arranged at a water injection circulating flow channel to make a cold water working medium directly reach the bottom of the heat collection tube, and the cold water working medium and a hot water working mediums are separated to prevent the mixing phenomenon of the cold and hot water working mediums. At the same time, bolts are welded to the outside of the connection tube in an implanted manner to fix the silica-gel sealing washer to make the connection of the connection tube and the heat collection tube have pressure receiving sealing performance.
