Description

The heat transfer unit (HTU) of solar energy vacuum tube

One, technical field

The utility model relates to the heat transfer unit (HTU) of parts, especially solar energy vacuum tube that solar energy utilizes, promptly from solar energy vacuum tube with the heat transfer unit (HTU) of energy conduction to water tank.

Two, background technology

The solar energy glass vacuum pipe has multiple mode to adopt heat, directly utilizes at first the convection current conduction of water, for the heat transfer efficiency that improves vacuum tube and prevent incrustation scale on the vacuum tube glass wall, with the also development to some extent of efficient heat-collecting device of heat pipe or U type pipe.Now, the product of vacuum pipe solar utilization has become nearly 10,000,000,000 yuan industry in China, and solar energy vacuum tube can produce 200-500 ℃ high temperature usually.How energy is delivered in the attemperater with alap loss and gone, perplex numerous production firms always.Present common pressure-bearing type separated type solar photo-thermal device, glass tube with vacuum Nei Caire is the most frequently used device, generally is with U type pipe, more uses heat pipe.

For the separated heat pipe conduction device, generally will lead heat flow tube punching and insert pipe box, after the welding heat pipe inserted in the pipe box and work, but these all make the processing technology complexity unavoidably, the quality guarantee difficulty strengthens, and also makes cost higher.

Three, summary of the invention

The utility model provides a kind of simple and practical mode in order to address the above problem, and is easy to realize the big production of scale; good integrity; convenient transportation mounting or dismounting, low, the handling ease of cost, reliability, economy and the conversion efficiency of simple its use of technology all are significant.

The purpose of this utility model is achieved in that the heat transfer unit (HTU) of solar energy vacuum tube, to heat pipe from glass-vacuum tube output energy, other is provided with and leads heat flow tube and contact with Heat Transfer of Heat Pipe on Heat Pipe one end of described output, on pressure-formed good conductor sheet material, be provided with heat pipe and embed runner, good conductor sheet material closely fixedly contacts with adopting heat pipes for heat transfer one end cross-like, and good conductor sheet material copper aluminum steel iron or its alloy are processed into.Make the shape shape of tight connecting mutually of leading heat flow tube and heat pipe top respectively

The heat pipe that other is provided with good conductor sheet material embeds runner, and two good conductor plate planes are rectified the closely contact of friendship formula intersection then.

Characteristics of the present utility model are: a kind of simple and practical mode is provided; be easy to realize the big production of scale; good integrity; convenient transportation mounting or dismounting, low, the handling ease of cost; technology is simple, economy and conversion efficiency are good, heat transference efficiency height, almost noenergy loss; easy to assembly, can guarantee long-term result of use.

Good conductor sheet material 3, to lead heat flow tube can be pipe 1, also can be that the cross section is semi-circular pipe 2, embeds good conductor plate 4, the heat pipe 5 of forming heat pipe, the raceway groove 8 of leading moulding on heat flow tube 6, the good conductor sheet material of special cross-section.

Five, the specific embodiment

As shown in the figure, Fig. 1 good conductor plate forms with copper, aluminium, iron and steel or its alloy processing and forming, can also embed runner and make the shape of tapering, being convenient to lead heat flow tube and heat pipe inserts in the flow passage structure of moulding, it can be round tube 1 that correspondence is led heat flow tube, also can be that the cross section is semi-circular pipe or D type pipe 2, the raceway groove 8 of good conductor plate forming be semi-circular hole or D type hole and lead heat flow tube and be complementary for circular hole or cross section also.The good conductor sheet material that heat flow tube is led in the insertion heat conduction sheet material that contacts with Heat Transfer of Heat Pipe on Heat Pipe one end of described output energy, and for the fixing contact of cross-like, can be right angle or other angle, the general technology such as weldering riveting that adopts is fixed contact.Add that outward heat-insulation layer and guard shield framework form the thermal-arrest plate.

As shown in Figure 3, the heat pipe that other is provided with good conductor sheet material embeds runner, intersects with the proper friendship formula of heat conduction stream pipe plate two good conductor plate planes then closely to contact.The closely fixing contact of end cross-like.Also the end of heat pipe can be made semicircular pipe or D shape pipe.

Two good conductor sheet materials can the perpendicular quadrature formula closely contact, and can also become the fixing contact in angle of inclination, all can at the 45-90 degree in the angle of inclination.Also can to the right left.

Good conductor sheet material becomes can the thin-wall metal cast structure.

Lead and be provided with the heat conduction insert in the heat flow tube, as described in Figure 4, be generally cross section that wire constitutes and be netted, radial, revolve wire.Be convenient to increase heat-transfer effect.

Leading can circulating water or other heat transfer medium in the heat flow tube.
