Description
Technical field
The utility model relates to a kind of, and a kind of solar energy heat collector that adopts the breakthrough form vacuum heat collection pipe promptly is provided, and by using this thermal-collecting tube, can reduce the solar energy heat collector production cost, and has significantly improved collecting efficiency.
Background technology
In the solar energy heat collector of prior art, the structure and the principle that are used for solar energy is converted to the electron tubes type solar energy heat collection pipe of heat energy are divided into three kinds:
One, shown in Fig. 4,5, is the present a kind of electron tubes type solar energy heat collection pipe that generally adopts and the schematic diagram of mounting structure thereof.Vacuum heat collection pipe as shown in Figure 4, its longitudinal section are double-deck elongated " U " shape, top is open, the bottom sealing and inside and outside space between two-layer is evacuated.As shown in Figure 5, for using the heat collector sectional view of aforementioned bilayer " U " shape vacuum heat collection pipe.Temperature improves after the cold water in the thermal-collecting tube absorbs solar radiant energy, and hot water proportion is little, therefore rises to the top boiler, otherwise cold water drops in the thermal-collecting tube of bottom formation free convection.Be arranged on the boiler on top and vacuum tube be regardless of lead into, export mouth, the thermal energy collecting that only utilizes free convection that solar radiant energy is transformed.And, can adopt the structure that as shown in Figure 6 vacuum heat collection pipe is linked to each other with heating water tank.
Two, shown in Fig. 7,8, the solar energy heat collector of mainly using in the engineering adopts " U " shape vacuum heat collection pipe as hereinbefore at present, both-side opening at the collector metal jar is horizontally disposed with into one group relatively, and will organize above-mentioned setting more and be arranged in parallel at grade.The cold water of introducing from collector metal jar bottom absorbs through heat collector and becomes hot water behind the solar energy and discharge from collector metal jar top.Said structure can utilize the free convection principle, but when heat collector separates with boiler, needs circulating pump to come forced circulation to add hot media (water).
Three, be depicted as heat-tube vacuum form of tubes heat collector as Fig. 9～11, the vacuum tube split shed end among Fig. 9 has the copper pipe of sealing, and the thermal medium that adds that heat transmission resistance is little, heat transfer efficiency is high is arranged in the copper pipe, forms heat pipe (HEAT PIPE) vacuum tube structure; Vacuum manifold absorbs solar radiant energy and converts thereof into and pass to the copper pipe that is enclosed in wherein behind the heat energy and add thermal medium, add thermal medium and rapidly heat is delivered to second in the heating water tank of copper pipe top and adds thermal medium (water), thereby reach the purpose (as Figure 10) that absorbs solar energy, storage heat energy.
Therefore, whether separate according to thermal-collecting tube and boiler and can be divided into integral type (as Fig. 6), separate type (as Figure 11); Integral type produces free convection and separate type needs circulating pump to come forced circulation to add hot media (water) in that boiler is inner.
But therefore above-mentioned vacuum heat collection pipe, can produce more heat-energy losses at night, cloudy day owing to adopted the mode that adds hot media (water) free convection, especially obvious for this phenomenon of the heat collector of integral type.For the structure of heat-pipe vacuum-tube and since its need through a centre add hot media (for example, copper pipe), therefore, the speed of its heat transfer is under some influence.
