Description

Air type heat exchange header Technical Field The utility model relates to the technical field of photo-thermal heating, in particular to an air type heat exchange header. Background The photo-thermal heating has high heat conversion rate, low running cost and high popularization value. At present, a heat collection system using air as a heat conducting medium is generally composed of a heat collector (composed of a two-way vacuum heat collection tube, a header and a bracket), a heat preservation air pipe, a wind-water heat exchanger (for exchanging heat in the air into water so as to facilitate heat storage and use), a circulating fan, a heat collection water pump (for driving water to circularly flow in the wind-water heat exchanger and the water tank) and a control system. When the sun irradiates the double-pass vacuum heat collecting tube, air in the double-pass vacuum heat collecting tube is heated and flows upwards along the double-pass vacuum heat collecting tube under the drive of the circulating fan, then flows out transversely after converging at the upper header, enters the wind-water heat exchanger through the heat preservation air pipe, finally enters the lower header through the heat preservation air pipe, and then circulates back into the double-pass vacuum heat collecting tube for repeated heating. . In this process, the circulating flow of air is driven by a fan on the insulated pipe. In the heat collection system, the wind-water heat exchanger is used as an independent device and a circulating fan to be connected in series on the heat preservation air pipe, and hot air heated by sunlight needs to flow out of the header before entering the wind-water heat exchanger for heat exchange. The circulating fan needs to drive all hot air to leave the header, the air quantity of the circulating fan needs to be large enough, the power requirement on the circulating fan is high, the cost and the electric power consumption of the circulating fan are high, the air-water heat exchanger needs to be an independent heat insulation box body, the manufacturing and transportation cost is high, and the manufacturing, transportation and installation costs are high and the occupied space is large due to the large air quantity of the circulating fan and the large diameter of the heat insulation air pipe.
