Description
Technical field
The utility model relates to a kind of flat-plate solar collector.
Background technology
In prior art, flat-plate solar collector is used for domestic solar water heater or solar engineering system, its runner is formed primarily of cold collector, comb and hot collector, wherein comb mainly plays heat-absorbing action, cold collector, hot collector mainly play shunting and the effect of confluxing, the length of cold collector, hot collector is longer, and the effective accounting of the heat absorption of comb and collector can be caused to reduce.The citation form of flat-plate solar collector runner mainly contains perpendicular grid-type (being similar to III font), horizontal grid-type (being similar to three fonts), snake type (likeness in form S font).First two runner form is the journey parallel channels such as typical multichannel, its complex structure, and technique soldering opening is more, and institute's consumption material is also more, causes that its production cost is high, difficulty is large; Snake type runner then belongs to a kind of single channel, and its too long in flow bend is too much, and cause its running resistance comparatively large, system dynamic role is poor, is difficult to the operation of the solar energy balcony water-heater system of reform of nature circulation.For overcoming these defects, spy improves the runner form of flat-plate solar collector.
Summary of the invention
Technical problem to be solved in the utility model to provide a kind of flat-plate solar collector, and its runner is relatively succinctly unimpeded, and manufacture relatively easy, and cost is lower, can balance the pluses and minuses of perpendicular grid-type, horizontal grid-type and snake type runner.
The technical scheme that the utility model solves the employing of its technical problem is: it comprises glass and housing, collecting core is provided with in the space that glass and housing surround, collecting core is primarily of the collecting core runner be connected to each other and absorber composition, collecting core runner is made up of some combs, cold collector and hot collector, cold collector, the equal one end open of hot collector, the other end is closed, and the tube wall of cold collector, hot collector is respectively equipped with storage mouth; Each comb is bent into the different U-tube of length, C type pipe or Contraband type pipe side by side, each comb formed short tube to surround by long tube and gradually to the parallel runner of external diffusion, comb one end is connected with the storage mouth of cold collector, the other end is connected with the storage mouth of hot collector.
Further, described U-shaped comb, C type comb or Contraband type comb are by input section, changeover portion and deferent segment composition, the input section of comb and the center line of solar thermal collector form angle α, and the deferent segment of comb and the center line of solar thermal collector form angle β.Angle α, β make the input section of comb and deferent segment in use form certain upstroke slope, and upstroke slope is beneficial to comb automatic vent, avoid it to produce vapour lock, and the smoothness of the hot fluid also in more suitable comb is run.
Further, the cross section of comb, cold collector, hot collector is circle, D font or ellipse, can also be the shape of other not rounded.
Further, the upper surface brazing of absorber and each comb, cold collector and hot collector.Connected mode is except brazing, and all right supersonic welding connection, Laser Welding connect, and also can be crimped by fastener.Absorber absorbs the heat of solar radiation, then by heat trnasfer heat is passed to the water in comb, cold collector, hot collector.
Further, it also comprises heat-insulation layer, and heat-insulation layer to be located in housing and to be positioned at below and the surrounding of absorber, and heat-insulation layer contributes to slowing down scattering and disappearing of the solar heat that heat collector absorbs.
Described cold collector, hot collector be arranged in parallel, and the length of cold collector is greater than the length of hot collector, and cold collector is positioned at the outer fix of hot collector.
Described cold collector, hot collector are coaxially arranged, and both length are identical.
Further, the openend of cold collector, hot collector is positioned at the same side of housing or the both sides of symmetry.
Further, each comb equidistantly distributes, not stacked mutually, and is distributed on absorber.
The utility model compares produced beneficial effect with background technology: because comb is bent into the different U-tube of length, C type pipe or Contraband type pipe by the utility model, and be distributed on absorber, as compared to the structure of perpendicular grid-type with horizontal grid-type runner, its heat absorption comb obviously increases with the effective accounting running collector, not only effectively reduce the consumption of runner copper material, decrease the quantity of runner soldering opening simultaneously, reduce manufacture difficulty and production cost, improve reliability.Each comb forms ascending, to besiege it ring upon ring each region of absorber multidiameter delay runner setting simultaneously, compared with snake type runner, effectively prevent because the too long in flow of its single channel and bend too much cause that running resistance increases, the problem of system dynamic role difference, therefore it can balance the pluses and minuses of perpendicular grid-type, horizontal grid-type and snake type runner.
