Abstract

The utility model relates to a heat absorbing plate device for a flat plate solar energy collector. A heat collecting plate and a sink plate are made of two layers of stainless steel plates. The heat collecting plate is folded into a ribbed arch which embosses horizontally, and the right end of the sink plate is folded into a longitudinal-sunk ribbed inlet groove. The left end of the sink plate is folded into a longitudinal-sunk ribbed outlet groove, and a bossy ribbed inlet groove and a concave ribbed outlet groove are in a crisscross which is welded with the spot welding. The utility model has the advantages of high bearing capacity, powerful absorption of heat, unique design, low cost and suitability for the volume production.

Description

A kind of flat-plate solar collector absorber plate device

Technical field

The utility model relates to a kind of solar thermal collector, especially a kind of flat-plate solar collector absorber plate device.

Technical background

The energy is the primary material base of current social development and human survival, along with the fast development of China's economic construction, and the reasonable utilization of the energy and being developed in order to influence the task of top priority of social development.The development and use of heliotechnics become the important content and the part of energy development strategy.The main contents that develop into heliotechnics exploitation aspect in solar water heater field.The solar water heater type kind of China's production and sales at present is a lot, but can be divided into vexed solarization type (comprising the plastics pocket type), plate, all-glass vacuum type and heat-tube vacuum cast four big classes basically.Vacuum tube water heater market-share growth speed is very fast, and vexed solarization type is slower with plate relative growth.Because China is developing country, and is underdeveloped, for satisfying numerous clients' needs, so the solar water heater product overwhelming majority is the cheap non-pressure-bearing product of price comparison, the pressure-bearing product is few, and vacuum tube water heater is many, dull and stereotyped water heater is few, and external product is opposite with China.And adopting extruding, drawing and forming mostly for the prior art of the critical piece absorber plate on China's flat-plate solar heat collector. common used material is based on rustproof aluminum alloy, the compound absorber plate of aluminum bronze also belongs to this technical costs height, material thickness is big, complex manufacturing technology influences the absorption and the transmission of the thermal efficiency.For this reason, developing the product that is fit to combine with building is the task of top priority, have only product to organically combine and be only the prerequisite that the solar water heater generally applies in big and medium-sized cities with building, key be develop better performances, cheap, be convenient to transport the reliable solar water heater of installation and operation.

Summary of the invention

The purpose of this utility model is to provide a kind of flat-plate solar collector absorber plate, this absorber plate novel structure, design uniqueness, the absorber plate that this product is mainly reflected in thermal-arrest adopts the two-layer stainless steel materials system of closing to form, technology is simple, cost is low, base plate is dull and stereotyped, the upper strata is for laterally having the intake tunnel of rib, the efficient heat absorbing coating of surface spraying, lower floor vertically goes up and is converted into the turnover tank for left and right end, two-ply is welded in by point that the system of closing forms all waterway channels and becoming one of absorber plate in the welding spot size of calculating; It is horizontal tank that this structure makes the top plate of absorber plate, and lower plywood becomes the turnover tank at two on vertically, the whole spot welding of two-ply joint makes whole mechanical structure at the stiffening effect that has laterally all played on vertically as gusset, the bearing capacity height of product.

The purpose of this utility model is realized by following technical scheme, has developed a kind of flat-plate solar collector absorber plate.This absorber plate is made by the two-layer corrosion resistant plate of tank plate of adopting hot plate and lower floor on upper strata, to adopt hot plate and be converted into lateral projection rib shape bar arch, the right-hand member of tank plate is converted into vertical recessed rib shape bar intake chamber, be converted into the effluent trough of vertical recessed rib shape at the left end of tank plate, the plane of hot plate and the vertically plane merging of tank plate will laterally be adopted, make the intake chamber and the effluent trough across of salient rib shape bar and recessed rib shape bar, this two-ply is welded with spot welding.

The chord length of described salient rib shape bar is that 12mm, camber are 2.5mm, is shaped as semicircle, and the distance between rib shape bar and the rib shape bar is 27.1mm, the number 30-40 of rib shape bar, and the thickness 0.75mm of every laminate.

The size of described spot welding is the even spot welding of 15mm * 8mm.

The utility model has the advantages that: this absorber plate novel structure, design uniqueness, the hot plate of adopting that this product is mainly reflected in thermal-arrest adopts the two-layer stainless steel materials system of closing to form, technology is simple, cost is low, and base plate is the Inlet and outlet water frid, and the upper strata is the intake tunnel that has rib, the efficient heat absorbing coating of surface spraying, the thermal-arrest ability is whole to be improved, and two-ply is welded in by point that the system of closing forms all waterway channels and becoming one of absorber plate in the welding spot size of calculating; In addition, it is horizontal tank that this structure makes the top plate of absorber plate, and lower plywood becomes the turnover tank at two on vertically, and the whole spot welding of two-ply joint makes whole mechanical structure at the stiffening effect that has laterally all played on vertically as gusset, the bearing capacity height of product, suitable a large amount of production.

Specific embodiment

Develop a kind of flat-plate solar collector absorber plate referring to Fig. 1-Fig. 4 the utility model, taked following steps:

This adopts hot plate 1 and tank plate 2 is made by two-layer corrosion resistant plate, to adopt hot plate 1 and be converted into lateral projection rib shape bar arch 3, the right-hand member of tank plate 2 is converted into vertical recessed rib shape bar intake chamber 4, be converted into the effluent trough 5 of vertical recessed rib shape at the left end of plate 2, the plane of hot plate 1 and the vertically plane merging of tank plate 2 will laterally be adopted, make the intake chamber 4 and effluent trough 5 across of salient rib shape bar arch 3 and recessed rib shape bar, this two-ply is welded with spot welding 6.

The chord length of described salient rib shape bar 3 is that 12mm, camber are 2.5mm, is shaped as semicircle, and the distance between rib shape bar and the rib shape bar is 27.1mm, the number 30-40 of rib shape bar, and the thickness 0.75mm of every laminate.

The size of described spot welding 6 is the even spot welding of 15mm * 8mm.

Those of ordinary skill in the art can understand, and in protection domain of the present utility model, makes amendment for the foregoing description, and it all is possible adding and replacing, and it does not all exceed protection domain of the present utility model.
