Description
Technical field
The utility model relates to a kind of middle temperature solar heat collector, belongs to the solar energy heat collector technology.
Background technology
Temperature solar heat collector in described in the utility model is that thermal-arrest medium heating temperature reaches a kind of solar thermal collector in 100 ~ 200 ℃ of scopes.
Prior art such as Chinese patent 200410064610.4 disclosed these class solar thermal collectors, the condenser that is U type structure by both sides involute section and the section that the parabolic segment transition is connected and symmetric arrangement constituted, be arranged in the thermal-collecting tube assembly in basic circle centre of the involute section of described condenser, and be used for supporting the bracing frame of described condenser and thermal-collecting tube assembly to form, described this class solar thermal collector is suitable for using on living facilities such as steamed rice, heat supply water.
Yet, this class solar thermal collector of prior art, still there are many structural deficiencies, select its main having: what the described condenser of the first adopted is that the glass base steel is sticked on film or the aluminium base structure that adds pad pasting, because its glass base steel is easily aging or distortion or cracking, and aluminium base weather resisteant is very poor, the pad pasting operation is pretty troublesome in addition, film system layer is bonding not only not firm, but also can carry many bubbles secretly, and has directly reduced the reflecting rate of its condenser; It two is that the condenser of prior art all is a front surface mirror, be that described reflector layer is provided in a side of glass base steel or aluminium base front surface, because described reflector layer is exposed to space outerpace, and to face the invasion and attack of adverse circumstances such as the corrosion of bearing atmosphere and the temperature difference and wind and weather, flying sands and howling wind directly; It three is the notch end and the two side ends of prior art condenser, all connect with extraneous space owing to do not establish cover plate, and cause described condenser inner chamber not only heat easily scatter and disappear, and very easily be subjected to the damage of external factor, and artificial cleaning is hard on very also.Because described structural deficiency, so that the reflecting rate of prior art condenser≤80%, and descend year by year, the reflecting rate when using 6 years drops to 30%.According to the test of Europe one tame research unit, to the solar energy thermal-power-generating condenser system of the equal scale of equivalent constructions, the every raising 1% of the reflecting rate of its condenser can be saved 700,000 Euros of investments by the quantity that reduces heat collector.
