the first heat collecting pipe 2 comprises an outer sleeve 6 and an inner sleeve 7, and sealing plates 8 are arranged at the upper ends of the outer sleeve 6 and the inner sleeve 7; the upper side of the inner sleeve 7 penetrates through the sealing plate 8 and is connected with the self-adaptive reversing device 9; the self-adaptive reversing device 9 comprises a reversing cylinder 10 and an outlet end 11 arranged in the middle of reversing, and a left inlet end 12 and a right inlet end 13 which are used for connecting the inner sleeve 7 are respectively arranged at two sides of the reversing cylinder 10;

the diameter of the sliding block 14 is smaller than the inner diameter of the reversing cylinder 10, so that the sliding block can slide in the reversing cylinder 10, and the sliding block has the similar function as a one-way valve, but has more advantages than the one-way valve; the whole flow is larger than the one-way valve, and when the flow velocity is larger, the vibration and abnormal sound of the fluid are lower, so that the reliability of the whole system is ensured; the outlet end 11 is connected with one end of a water outlet pipe 16, the other end of the water outlet pipe 16 penetrates into the heat exchange box body 4 and is connected with a three-way pipe 17, two sides of the three-way pipe 17 are respectively connected with one ends of a first water return pipe 18 and a second water return pipe 19, and the other end of the first water return pipe 18 penetrates through the heat exchange box body 4 and is connected with a sealing plate 8 of the first heat collecting pipe 2;

the temperature of the water outlet pipe 16 entering the heat exchange box body 4 is increased, and certain heat exchange efficiency is improved; although the temperature loss of the first water return pipe 18 and the second water return pipe 19 is increased; however, the lower the temperature of the water is, the higher the heat absorption efficiency is, and the temperature of the first water return pipe 18 and the second water return pipe 19 is reduced, so that the heat absorption efficiency of the system is increased; the total heat of the whole system is not reduced basically while the heat loss of the water outlet pipe is reduced; a first circulating pump 20 is arranged on the first water return pipe 18, and a second circulating pump 21 is arranged on the second water return pipe 19;
