Abstract
The utility model relates to a stainless steel heat absorption plate core for a solar heat collector, which mainly consists of a connecting header pipe (1), a connecting header pipe (5), a heat absorption coil (3) and a fin (4). The heat absorption plate core is characterized in that the plate core adopts the materials of stainless steel and the fin which have good welding performance. The connecting header pipes and a heat absorption pipe are connected by adopting a welding process; and the fin stamped to be in the shape of the parabolic and prismatic face and the heat absorption coil are welded together by adopting the self-fluxing and welding process. The utility model has the advantages of simple process, low manufacture cost and better pressurization and thermal properties, and can be used for making various solar heat collectors.
Description
Technical field
The utility model belongs to a kind of flat-plate solar heat collector heat-absorbing plate core.
Background technology
For energy savings and protection environment, each state of the world today all utilizes solar energy at active development, and solar water heater is to use the earliest product the most widely.Especially the plate type solar water heater is fit to make high performance pair of circulation pressure-bearing type solar water heater, along with the each side continuous advancement in technology has bigger development because its structure easily combines with building.According to standard GB/T6424-1997 " plate type solar water heater technical conditions ", the version of absorber plate has tube-sheet type, wing pipe type, flat box type, coil pipe type.
Flat-plate solar heat collector in the production and sales of present China, most copper aluminum composite pipes plate structures or full copper pipe plate structures of adopting.According to Chemical Industry Press's the 1st edition " solar water heater and system " book introduction January in 2007, the copper aluminum composite pipes plate structure is copper pipe to be placed between two aluminium sheets roll together, and then with the moulding of pressure-air inflation.Roll to make and reach the metallographic combination between copper pipe and the aluminium sheet, thermal resistance is very little, thermal efficiency height.But complex process because of being that the copper aluminum composite pipes plate structure can not be directly and the connecting pipe welding, must be done transition with a bit of copper pipe and connect again, and an end is high temperature solder brazing, and the other end is the low temperature solder, and the welding job amount is big, and withstand voltage reliability is low.Analyze according to 2006 the 6th phases " solar energy " magazine " flat plate solar water heater general situation of development both at home and abroad " literary composition, market plate type solar water heater portion descends year by year at home in recent years, yet the plate type solar water heater still accounts for dominant position now abroad, domestic market share main reasons for decrease: the one, the product hot property is lower than the foreign same type product, the 2nd, material therefor price height, production scale is little, the manufacturing cost height, do not have price advantage, influenced of the popularization and application of plate type solar water heater in China.
Summary of the invention
The purpose of this utility model provides that a kind of welding procedure is simple, and the cost of material is low, the reasonable solar thermal collector heat-absorbing plate core of hot property.
In order to achieve the above object, the utility model adopts the stainless steel tube plate structure, heat-absorbing plate core is welded by stainless steel tube and fin, suitably dwindle tube pitch in order to improve hot property, strengthen fin area, fin is rolled or strikes out parabola cylinder shape, heat absorption comb and fin adopt argon arc from fusion welding.
The utility model does not need transit joint owing to adopt the stainless steel tube plate structure, the heat absorption comb can be directly and connecting pipe weld.Because fin adopts parabola cylinder shape, has increased endotherm area relatively, and before and after when making heat-absorbent surface at noon in long time some maintenance vertical with sunray, play tracer action, can absorb more solar radiation energy.29-30 day in January, 2008 has been done the contrast experiment in Harbin, and the utility model is than high 5-6 ℃ of copper aluminum composite pipes plate structure heat collector heat-collecting temperature, and the preliminary proof of experiment hot property is higher than the copper aluminum composite pipes plate structure.
The utility model is owing to architecture advances, and hot property improves, and can select for use price lower, and welding technological properties is stainless steel material preferably, reduces production costs, and favourable applying will produce good economic benefits and social benefit.

The specific embodiment
The utility model shown in Figure 1 by: go up connecting pipe 1, go up connecting pipe joint 2, heat absorption comb 3, fin 4, down connecting pipe 5, connecting pipe joint 6 constitutes down.Heat absorption comb 3 two ends weld together with 1 time connecting pipe 5 of last connecting pipe respectively, at connecting pipe two ends welding screwed pipe joint 2 and 6 up and down, are used to connect circulation line, and parabola cylinder shape fin 4 is welded on the heat absorption comb 3 in order to improve hot property.
The utility model load performance, hot property are all better, can be used for making various solar thermal collectors.
Claims (1)
1. a stainless steel solar heat collector heat-absorbing plate core is made up of connecting pipe, heat absorption comb and fin, is welded with parabola cylinder shape fin (4) on the comb (3) that it is characterized in that absorbing heat.
