Abstract
The utility model provides a forced circulation collection box with heat-exchange fin for solar energy water-heater which is composed of a collection box, a water inlet and outlet tube and a vacuum heat collecting tube. Three branching tubes are arranged between the water inlet and outlet tubes in the collection box. The branching tube is vertically welded with a plurality of heat-exchange fins. The bearing heat-exchange medium is operated in the pipeline and forms the heat exchange by the high temperature heat air in the sealed space which is formed by the heat-exchange fin, the collection box and the vacuum heat collecting tube. The forced circulation collection box with heat-exchange fin for solar energy water-heater also can make the branching tube be arranged into the u-shaped tube. The u-shaped tube is vertically welded with a plurality of heat-exchange fins and is placed in the vacuum heat collecting tube. Both ends of the u-shaped tube are respectively communicated with the water inlet and outlet tube in the collection box. The bearing heat-exchange medium through the water inlet tube enters the u-shaped tube to exchange the heat and then the bearing heat-exchange medium is aggregated by the water outlet tube to flow out. The system of the forced circulation collection box with heat-exchange fin for solar energy water-heater is composed of a plurality of sets unit collection boxes connected in series and connected in parallel. The forced circulation collection box with heat-exchange fin for solar energy water-heater has large heat-exchange area and high thermal efficiency.
Description
1, affiliated technical field:
The utility model belongs to solar water heater, especially mandatory circulation solar water heater.
2, background technology:
Known forced circulation solar water heater is organized series and parallel operation pressure-bearing heat transferring medium by the heat-collecting box unit more and is carried out heat exchange, and the header of unit heat-collecting box and vacuum heat collection pipe are as direct bearing structure, and long-term bearing operation can be revealed.Or in header and vacuum heat collection pipe, be provided with flow-path tube operation pressure-bearing medium, because the heat exchange area of the accessory structure of its runner and known expansion heat exchange area can increase limited, can't effectively reduce interior air of header and extraneous convection current in addition and cause heat waste bigger, complete machine heat is imitated low.
3, summary of the invention:
For overcoming above-mentioned the deficiencies in the prior art, the invention provides a kind of forced circulation solar water heater header with heat exchange fin, many group sheet heat exchange fins are set, to improve its heat exchanger effectiveness on the pipeline of bearing operation.
The utility model adopts following technical scheme: adopt flow dividing structure between water inlet pipe with the header of heat-insulation layer (1) (5) and outlet pipe (3), three isocons (4) are set, and (20 tight suits are fixed on the isocon (4) more with the heat exchange fin of organizing sheet.Vacuum heat collection pipe directly is connected on the header by the silica gel circle, and header and vacuum heat collection pipe constitute enclosure space like this, fill heat-conducting medium in enclosure space.During operation, heat-conducting medium is heated the back and forms nearly 200 degree high temperature, at vacuum heat collection pipe---and slow convection current header in, the heat exchange fin of organizing sheet is heated more, conducts heat to the heat transferring medium of the bearing operation in the isocon and is pulled away.
Heat exchange fin of the present utility model also can adopt another kind of scheme, it is placed in the vacuum heat collection pipe, its structure is: the water inlet pipe (5) that to be provided with one one end in being provided with the header of heat-insulation layer (1) be blind pipe, the outlet pipe (3) that to be provided with one one end be blind pipe, isocon is arranged to U type pipe (7), be placed in the vacuum heat collection pipe (6), U type pipe is provided with the heat exchange fin (2) of many group sheets.The water inlet of many group U type pipes and delivery port communicate with water inlet pipe (5) and outlet pipe (3) in the header respectively.During the operation of pressure-bearing heat transferring medium, the U type pipe that enters the band heat exchange fin in the vacuum heat collection pipe by water inlet pipe respectively flows out after the heat transferring medium after the heat exchange is pooled to outlet pipe respectively.
The utility model beneficial effect is: above two kinds of structures all can form the larger area heat exchange structure according to the heat exchange fin group that adopts greater density under certain cost prerequisite, the heat exchange fin group of this kind form can effectively reduce the heat waste that the hot-air in the header leaks and produces in addition, has improved the solar water heater thermal efficiency.

Accompanying drawing 1, be the utility model overall structure schematic diagram
Accompanying drawing 2, cut open structural representation for the utility model side
Accompanying drawing 3, cut open structural representation for the side of second embodiment of the utility model
Among the figure: 1, header; 2, heat exchange fin; 3, outlet pipe; 4, isocon; 5, water inlet pipe;
6, vacuum heat collection pipe; 7, U type pipe
5, specific embodiment:
Header of the present utility model is a round barrel shape, its outer heat-insulation layer that is provided with, the inlet tube and outlet tube of header is connected with prime, level unit, back heat-collecting box respectively, three copper isocons in the header, multi-disc aluminium matter or copper heat exchange fin are decided in its outer vertical sleeve solid welding, its spacing 2-10 millimeter equidistantly has three holes on heat exchange fin, so that evenly carry out heat exchange.
The utility model is in another embodiment shown in Figure 3, and the vertical solid welding of heat exchange fin is on copper U type pipe, and the heat exchange fin number can be provided with according under certain cost prerequisite, and its spacing can be 2---and 10 millimeters.
Claims (2)
1, a kind of forced circulation solar water heater header with heat exchange fin is made up of header (1), water inlet pipe (5), outlet pipe (3), vacuum heat collection pipe (6) etc.; It is characterized in that: between water inlet pipe (5) in header (1) and the outlet pipe (3) two isocons (4) are set at least, heat exchange fin (2) is set on the isocon (4).
