Description
Technical field
The utility model relates to a kind of heat-exchange device.Be to be used for collecting heat energy and to give the heat build-up pipe of medium specifically, be applicable on the solar water heater aqueous medium is heated, also can be used for the compressed air of gas such as compressed air engine is heated thermal energy transfer.
Background technology
As everyone knows, in some occasions that need heat liquid medium or gas medium, all be provided with heat-exchange device.For example, the heat build-up pipe on the solar water heater is exactly this heat-exchange device.
At present, the heat build-up pipe that uses on the solar water heater all is a pipe, and this pipe is a single layer structure.Though adopt pipe also can realize heat build-up, so that the running water in managing is heated.But the exterior surface area of pipe is limited, and it is less to receive the irradiation of sunlight area, therefore, adopts the solar water heater of this heat build-up pipe, to running water to add thermal effect relatively poor.Because this heat build-up pipe is a single layer structure, at the cloudy day of cold season, the liquid medium in it easily freezes again.In case the liquid medium in the heat build-up pipe freezes, the heat build-up pipe is just fragile, and therefore, the service life of this heat build-up pipe is not long.
The utility model content
Problem to be solved in the utility model is the defective that overcomes background technology, a kind of heat-exchange device is provided.This heat-exchange device, long service life.Adopt the solar water heater of this heat-exchange device, heat effective.
For addressing the above problem, take following technical scheme:
Heat-exchange device of the present utility model contains the heat build-up pipe.Be characterized in that described heat build-up pipe contains interior pipe and outer tube, pipe and outer tube are metal tube in this, and their cross section is polygonal.Leave spacing between interior pipe and outer tube.Wherein, the outer surface of interior pipe vertically has brace rod, in this brace rod is on the angle of pipe and corresponding with the respective corners of outer tube.All there is interface at the inner and outer pipe two ends, and through hole and end socket are arranged on the interface, and the spacing between inner and outer pipe communicates with through hole.In the spacing of interior pipe and outer tube with in the interface heat-conducting medium is arranged all.
Interface tube and outer interface tube in described interface contains.Interior interface tube contains base, and identical, the equal and opposite in direction of the shape of cross section of shape and interior tube cavity and the two are and seal shape and link together around the base.Through hole is arranged, oriented projecting tube around the through hole in the middle of the base.Outer interface tube is a tubular, its inner end medial surface shape identical with outer tube lateral surface shape and the two be the sealing shape link together.There is capping the outer tube outer end, is the sealing shape and cooperates around the capping with between the outer tube outer end.There is through hole at the capping center, and the pipe on the base penetrates in this through hole.
Through hole on the interface is on the sidewall of outer tube interface.Be furnished with joint in the through hole wherein, this joint is a tubulose, is the sealing shape between its inner end cylindrical and through hole and cooperates, and its outer end is furnished with end socket.
The outer end of projecting tube is fixed with flange.
Described end socket is a tubulose, and its outer end is closed, and circle upward and on the cylindrical of joint outer end all has screw thread in its inner end, and the two is sealing by this screw thread and detachable shape is combined together.
Take such scheme, have following effect:
Because pipe and outer tube in its heat build-up pipe of heat-exchange device of the present utility model contains, cross section of pipe and outer tube is polygonal in this, makes their surface area increase greatly, it is calculated that their surface area is 2 times of pipe surface area.Especially outer tube, surface area one increases, and its area that receives sunshine is just big, therefore, adopts the solar water heater of this heat-exchange device, and it is all right that it adds thermal effect.
Owing to all be filled with heat-conducting medium in the spacing of interior pipe and outer tube He in the interface, even at the cloudy day of cold season (subzero below 30 ℃), the liquid medium in it can not freeze yet again.Because the liquid medium in the heat build-up pipe can not freeze, the heat build-up pipe is just not fragile, and therefore, the service life of this heat build-up pipe is longer.
