Abstract

The utility model relates to the technical field of a solar energy utilization device. An upper panel and a lower bottom plate of the utility model for heat collection are corrugated plates having symmetrical shapes; the left and the right sides of the corrugated plates are welded after hemmed in a labyrinth shape or are welded together after sliver plates are added, and the front and the rear ends are directly welded with an upper and a lower communication pipes; in addition, liquid flowing cavities formed among the communication pipes and the upper panel and the lower bottom plate are communicated; the symmetrical positions of the surfaces of the upper panel and the lower bottom plate are fixedly provided with reinforcing ribs. The utility model has the advantages of high heat efficiency, good rigidity, freeze protection and low cost.

Description

Double-deck corrugated metal sheet solar thermal collector

The utility model relates to technical field of solar energy utilization equipment.

Existing solar thermal collector, from plate shaped, focus type, canalis pterygoideus shape, all have following deficiency up to advanced vacuum tube type: 1. the rigidity of heat collector is not enough, under low hydraulic pressure effect, will be out of shape seepage as its metal flat case of flat plate collector, cause that steam fog fills the air in the glass plate chamber, reduced hot case effect; 2. the anti-freezing disruptiveness of heat collector is poor, and for example finned and heat pipe type easily break under the severe cold in the winter time, and the example that damages that wherein all breaks also has record; 3. no matter be continuous wing cast or heat pipe type, unit daylighting area cost is all higher, consumers in general still impotentia purchase and full-time thermal absorptivity on the low side or the like, influence and limited the promotion and application of solar water heater.

The purpose of this utility model provides a kind of double-deck corrugated metal sheet solar thermal collector, its thermal efficiency height, good rigidity, can be antifreeze and cheap.

The purpose of this utility model can reach by following technical measures: the top panel of heat collector thermal-arrest and lower shoe are the corrugated sheet of shape symmetry, their left and right sides with the labyrinth type flanging after welding or lengthening weld together behind the batten, and forward and backward two ends directly with upper and lower communicating pipe welding, and the liquid flow cavity that constitutes between communicating pipe and top panel and lower shoe communicates.Top panel and lower shoe surface symmetric position have been fixed reinforcement.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, present embodiment is used for flat-plate solar heat collector, the heat collector core that is positioned under the light penetrating panel is made of corrugated thermal-arrest top panel 1 and lower shoe 2, traditional comb and fin conjoined structure form have been replaced, owing to contact thermal resistance between no tube sheet, and thermal resistance is also very little between plate liquid, and does not have the Temperature Distribution gradient.Thereby can make full use of the solar energy of collection, the more traditional water heater of the thermal efficiency is significantly increased.For improving withstand voltage properties, plate and lower shoe surface symmetric position has been screwed reinforcement 3 in the above, to adapt to the big occasion of pressure of supply water.This device has higher daylighting, keeps in repair easy, economical and practical.

Preparation method: corrugated top panel and the lower shoe of gathering heat adopt punch forming, and base plate is compacted into labyrinth type at the dual-side turnup and with top panel, and in addition sealing or screw connect then; Upper and lower both sides fold the right angle face of certain altitude along wavy line, add respectively at two ends that then a block length square plate and last lower communicating tube weld, with direct current weldering or soldering all can, so just constitute a double wave plate shape heat collector.No seepage and no leakage is qualified behind the requirement dress water.

Claims

1. double-deck corrugated metal sheet solar thermal collector, it is characterized in that: top panel of thermal-arrest (1) and lower shoe (2) are the corrugated sheet of shape symmetry, their left and right sides with the labyrinth type flanging after welding or lengthening weld together behind the batten, and forward and backward two ends directly with upper and lower communicating pipe welding, and the liquid flow cavity that constitutes between communicating pipe and top panel and lower shoe communicates.

2. solar thermal collector according to claim 1 is characterized in that: the fixing reinforcement (3) of plate and lower shoe surface symmetric position in the above.
