Embodiment

Please refer to shown in Fig. 1 to Fig. 2, water circulation heat exchange solar heating engineering system before the present invention, this system comprises millpond 1, thick worry net 2, recycle pump 3, water distributor 4, heat absorption plate 5, water leg 6, secondary filter 7, light-passing plastic insulation film 9 and foam thermal insulation backboard 10, described millpond 1 connects described thick worry net 2 (for carrying out tentatively filtering) to water by the first pipeline 81, this is slightly considered net 2 and connects described recycle pump 3 by second pipe 82 again, and this recycle pump 3 is for being raised in described water distributor 4 by the water extraction in described millpond 1; Described recycle pump 3 is connected with described water distributor 4 by the 3rd pipeline 83, and this water distributor 4 is positioned at the top of described high-end water inlet place of heat absorption plate 5; Described heat absorption plate 5 is positioned at the position of eminence illumination abundance, this heat absorption plate 5 is the smooth plate being coated with and being brushed with highly selective heat-absorbing paint, or it being coated with the roof boarding being brushed with highly selective heat-absorbing paint, wherein said smooth plate or roof boarding all tilt an angle [alpha], and 3 ��ܦ��45 ��. Described water leg 6 is positioned at the lower section of described heat absorption plate 5 low side water outlet place, the water flowing through heat absorption plate 5 for collecting, and this water leg 6 is also connected with described secondary filter 7 (for comparatively comprehensively being filtered by the water after heat exchange) by the 4th pipeline 84, this secondary filter 7 is connected with described millpond 1 by the 5th pipeline 85 again. Wherein, described water distributor 4 is one with the pipe of uniform small pores or an arc groove; Described millpond 1 is survived the winter for swimming pool or aquatic products and is cultivated pond.

Described light-passing plastic insulation film 9 is covered in described heat absorption plate 5 and circulates the top of the water surface, for suppress the minute surface of water reflective, reduce the convection heat losses of air and the evaporative heat loss of water; Described foam thermal insulation backboard 10 pad in the lower surface of described heat absorption plate 5, for reduce heat absorption plate 5 heat scatter and disappear. Certainly, when running into continuous rainfall sky, in order to keep the temperature of water in millpond 1, we also need additionally to take artificial heat insulation measure, and Application comparison is many in the prior art for these, just seldom introduce here; Meanwhile, in order to flow in millpond 1 with preventing excessive rainfall, it may also be useful to the water overfill in pond 1, we can arrange a switch on the pipeline of water leg 6, is used for the connection of pilot piping or closedown.
