Description

A kind of arcs of recesses reflection plate-type solar water heater

The utility model belongs to the heating equipment class, relates in particular to the solar water heater class.

Solar energy be inexhaustible, use intact, cheap, pollution-free, safe, the abundantest natural energy resources.People for work, learn, the needs of aspect such as life, produce various solar facilities, as vexed solarization, flat board, the vacuum heat-collecting tubular type solar water heater that occurs on the market, by the solar energy hot-water supply.Since this water heater critical piece---reflecting plate all adopts flat, there also have only a few to adopt to be corrugated, bottom reflecting plate between its thermal-collecting tube is flat board or convex, theorem and practice according to optics, when this flat board of sunshine vertical irradiation or convex globoidal, light must return penetrates or is scattered back the space; When the sunshine oblique fire, light also can or be scattered back the space from reflection between the thermal-collecting tube, and therefore, the reverberation that the thermal-collecting tube back side, side are subjected to is limited, and this type of solar water heater supply water temperature is not high, and water temperature in winter is particularly lower.Simultaneously, this type of solar water heater generally all adopts the thin, planar plate, and structural strength is low, and the ability of natural calamities such as opposing wind, rain, snow, ice, hail is all very poor.

The purpose of this utility model provides a kind of solar water heater of new type reflection plate, both can all shine, reflect front, side and the back side with shining sunshine on the reflecting plate area in thermal-collecting tube, improve the thermal efficiency of solar energy, can strengthen the structural strength of reflecting plate again.

The purpose of this utility model is achieved in that changes system into several arcs of recesses curved surfaces with the reflecting plate of solar water heater by plane, constitutes the arcs of recesses reflecting plate.This arcs of recesses reflecting plate is by the base top of clamp structure (as screw, rivet, weldment, gluing, edges of boards and base snap-in or other member etc.) device at solar water heater; Thermal-collecting tube is equipped with in the concave arc curved surface top of arcs of recesses reflecting plate, can communicate with the water source.When solar light irradiation arcs of recesses reflecting plate, the front of thermal-collecting tube is subjected to the direct projection of sunshine; Sunshine between the thermal-collecting tube has increased the area of solar radiation, thereby has significantly improved the thermal efficiency and the water outlet temperature of solar water heater through the focusing of reflecting plate arcs of recesses curved surface or reflection and be radiated thermal-collecting tube back, side.Simultaneously, the arcs of recesses reflecting plate has changed shape, has strengthened structural strength, has improved the ability of natural calamities such as opposing wind, rain, snow, ice, hail.

For improving solar heat efficient, adapt to many-sided needs, can be shaped on its arcs of recesses reflecting plate of the utility model and the corresponding arcs of recesses curved surface of thermal-collecting tube quantity, the top of curved surface is equipped with thermal-collecting tube respectively; Adjacent arcs of recesses curved surface can be close to along its edge line and lean on, make thermal-collecting tube with sunray all enter in the two adjacent arcs of recesses curved surfaces, reflex to the back and the sidepiece of thermal-collecting tube; Be the needs of making and reducing cost, the arcs of recesses reflecting plate can adopt reflecting type, compound reflecting formula or heat absorption type material to make; It can install on the top of solar water heater bases such as vacuum heat-collecting tubular type, flat, closing-sunning type, makes diversified solar water heater.

The utility model has been owing to adopted above technical scheme, thereby can significantly improve solar heat efficient and hot water temperature, and can increase structural strength, economical with materials, reduce cost, also have characteristics such as novelty, the easy pin of system attractive in appearance, energy-conservation, practical, easy, economic results in society are huge.
