A kind of novel heat collector
Technical field
The utility model relates to a kind of solar utilization technique, particularly a kind of novel heat collector.
Background technology
The common kind of solar thermal collector is the direct insertion heat collector of vacuum tube, heat pipe collector, U type pipe heat collector at present.The direct insertion heat collector of vacuum tube is easily scalded the people because of directly leaking water in the vacuum tube after the pipe breakage, so be restricted installing, heat pipe collector is that less because of collector area, effect is not fine by heat pipe condensation end heat radiation heat medium.U type pipe heat collector U type runner is blocked by incrustation scale easily.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed that a kind of Heat-collecting effect is good, the novel heat collector of long service life.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of novel heat collector, be provided with solar energy heat collection pipe, inner flow tube and water-supply-pipe, be characterized in: inner flow tube is inserted in the solar energy heat collection pipe and is provided with solar energy heat collection pipe is concentric, the bottom of inner flow tube is provided with water export, described water-supply-pipe is formed by inner sleeve and outer tube suit, one end of inner sleeve is the cold water water inlet, the other end sealing of inner sleeve, one end and the inner sleeve of outer tube are tightly connected, the other end of outer tube is a hot water outlet, cavity between outer tube and the inner sleeve constitutes the hot water flux, the upper end of described solar energy heat collection pipe is taken over by bite type joint and cutting ferrule and is connected with outer tube, and communicates with hot water flux between the inner sleeve with outer tube, and the upper end of described inner flow tube is connected and is communicated with inner sleeve.
Cold water is entered by the inner sleeve of water-supply-pipe, the inner flow tube of flowing through downwards, and after being heated between inner flow tube and the solar energy heat collection pipe cavity, hot water upwards flow to the outer tube of water-supply-pipe and the hot water flux between the inner sleeve, by the hot water outlet outflow of outer tube.The utility model compared with prior art adopts solar energy heat collection pipe, and the glass tube of solar energy heat collection pipe does not directly contact with water, the pipe long service life, and many solar energy heating tube side-by-sides use, and its Heat-collecting effect is good, and is safe and reliable.

The specific embodiment
A kind of novel heat collector is provided with solar energy heat collection pipe 6, inner flow tube 3 and water-supply-pipe.Described water-supply-pipe is formed by inner sleeve 1 and outer tube 2 suits, one end of inner sleeve 1 is the cold water water inlet, the other end sealing of inner sleeve 1, one end and the inner sleeve 1 of outer tube 2 are tightly connected, the other end of outer tube 2 is a hot water outlet, and the cavity between outer tube 2 and the inner sleeve 1 constitutes the hot water flux.Inner flow tube 3 is inserted in the solar energy heat collection pipe 6 and solar energy heat collection pipe 6 concentric settings, and the bottom of inner flow tube 3 is provided with water export.The upper end of solar energy heat collection pipe 6 is taken over 4 by bite type joint 5 and cutting ferrule and is connected with outer tube 2, the upper end of solar energy heat collection pipe 6 just is connected with outer tube 2 and has communicated with hot water flux between the inner sleeve 1 with outer tube 2 like this, and the upper end of inner flow tube 3 also is connected and is communicated with inner sleeve 1.
