Description

Two-sided thermal-arrest high-efficiency solar flat casing water-heater

The invention belongs to thermal technology's mechanical field, ordinary flat formula heat collector is a kind of simple cheap, the wider solar water heater of application.But its heat loss is big, energy conversion efficiency is low.This significant deficiency is for improving the also different existence of degree of other flat-plate collectors of back.At present, the all-glass vacuum tube type heat collector has overcome this defective preferably.Yet its technology, structure more complicated, cost height.

When running into rain, snow, dust storm, dust etc. during this two classes heat collector uses in addition and polluting, operating efficiency and quantity of heat production all can descend greatly.

The purpose of this patent is, utilizes water, the fine and turning point of poor thermal conductivity of the transparency.Simultaneously again with the heat insulation principle of water, formulate a kind of multilayer current, reflection up and down with water ballast heat, two-sided thermal-arrest is for changeing the efficient solar flat-board formula water heater of levying.Make its collecting efficiency and unit are heat-collecting capacity not only be higher than ordinary flat formula heat collector, also be higher than the electron tubes type heat collector with area, and its structure is more simple and reliable, cost is lower than the two, is convenient to insulation and protects self not contaminated, longer service life.

This patent is divided into fixed and connects two kinds on type when using by dress.Fig. 1 is used for ground, roof, platform etc. to go up the two-sided thermal-arrest high-efficiency solar of fixed flat casing water-heater.Among the figure: 1-expansion bolt (being used for the windy area of waiting), 2-after-poppet, 3-support stay cord, protecting cover under the 4-, reflecting plate under the 5-, protecting cover stay cord under the 6-, the 7-bolt of restricting, the 8-water inlet pipe, the 9-pulley, 10-downcomer, 11-outlet pipe, 12-valve, 13-water level meter, 14-water tank, 15-upper hose, 16-adjusting bracket, the 17-wing bolt, the last reflecting plate of 18-, the last protecting cover of 19-, the 20-water heater, the 21-fore-stock, the 22-adjusting bracket is defended.

Fig. 2 is the enlarged drawing of water heater among Fig. 1, among the figure: the 10-downcomer, 15-upper hose, 20-1 are frameworks, and 20-2 is glass outer (or other transparent panels), and 20-3 is inner layer glass (or other transparent panels), and 20-4 is two-sided thermal-arrest plate, 20-5 is a discharging valve.

The principal character of this patent is the centre that its two-sided thermal-arrest plate 20-4 is positioned at water heater 20.It is the flat board that surface, a two sides is selectivity black matrix material, and each rain piece of inner layer glass 20-3 and glass outer 20-2 lays respectively at the both sides of two-sided thermal-arrest plate, and is parallel to each other and certain space arranged each other.Wherein two inner layer glass sides are with the top sealing and be communicated with upper hose 15.Lower openings is communicated with the glass outer internal pore, and two glass outer peripheries are sealingly fastened on the framework and with downcomer 10 and are communicated with.

Another feature of this patent is (Fig. 1): the water heater upper and lower has the reflecting plate that is minute surface, wherein go up protecting cover 19 and go up the top that reflecting plate 18 is positioned at water heater 20, reflecting plate 5 was positioned at the below of water heater under following protecting cover 4 reached, whenever both connect by adjusting bracket 16 respectively, after wing bolt 17 is unclamped in the field, but upper and lower reflecting plate all relatively hot hydrophone rotates, to adjust that with relative angle position.Tighten wing bolt 17 then and fixed, wherein descend the reflecting plate other end to spur (shown in four-headed arrow among Fig. 1) up and down by following protecting cover stay cord 6 again and regulate its position.Then with stay cord one auspicious being fixed on the rope bolt 7.

This patent the 3rd feature is that the upper end and the water heater framework 20-1 of after-poppet 2 connects, and the lower end is connected with fore-stock 21 with support stay cord 3 by the rope bolt.Regulate the inclination angle of stay cord 3 length adjustable heat hydrophones, and adjusting bracket is defended 22 two ends and is connect with fore-stock 21 and following protecting cover 4 respectively.

The principle of this patent is (Fig. 1, Fig. 2): after water inlet pipe 8 water inlets, water is full of between water heater 20 each layer glass and the thermal-arrest plate.In the middle of the sunlight (Fig. 1 C to) partly by glass and water direct irradiation in thermal-arrest plate upper face, top sunlight then is mapped to reflecting plate 18 through reflecting along D to also penetrating above the thermal-arrest plate.Bottom sunlight then under the directive reflecting plate 5 refraction backs along E to penetrating in thermal-arrest plate lower surface.Make thermal-arrest plate two sides exposure, more than 2 times of the quite common heat collector of heat-collecting capacity, solar radiant energy is absorbed back temperature rising by the black material of stopping in thermal-arrest plate two sides, heats the water (dotted arrow among Fig. 2) between two-sided thermal-arrest plate and the inner layer glass.Hot water enters water tank 14 along plate face rising edge B to the upper hose 15 of flowing through, and water tank lower floor then flows to the space downward (double-lined arrow among Fig. 2) that enters by downcomer between the inside and outside layer glass along A than cold water.Walk around that the space enters between thermal-arrest plate and the inner layer glass between bottom internal layer glass and the framework, be heated rising once more, as with continuous circulation.Because water layer plays important heat insulation effect between skin and the inner layer glass.Heat loss is greatly reduced, can manage conversion efficiency and greatly improve.

This patent can unclamp wing bolt and stay cord at any time when rain, snow, hail, dusty wind weather or other dust are serious, upper and lower cover plate rotation displacement (as two-way curved arrow among Fig. 1) is covered water heater up and down protected.This protected mode also is applicable to the insulation under the situations such as not having sunlight in night or season, makes water heater avoid polluting and makes dirty.Variations in temperature is little, and is in shape all the time, prolongs its working life.

Fig. 3 be this patent another kind in window etc. locate by the dress pattern---connect the two-sided thermal-arrest high-efficiency solar of type flat casing water-heater.Its main member water tank, water heater, protecting cover, reflecting plate etc. are all identical with said fixing formula structure up and down, operation principle too, different members be: the 23-bolt of restricting, each member stay cord of 24-, 25-are fixed on the wall each than joint chair, the 26-body of wall, the 27-window frame, the 28-window, water tube hose under the 29-, the last water tube hose of 30-, 31-pulley bracket (being fixed on the body of wall), the 32-rope hook, 33-pulley spindle, 34-pulley.The structure body of all the other labels is identical with Fig. 1.

The feature that this patent connects type is: water heater, protecting cover and reflecting plate be all by connecing than joint chair 25 and body of wall 26 up and down, and each is with rope bolt 23, structure body stay cord 24, and pulley 34 is connected with rope hook 32.The angle of inclination that Duola's rope can be regulated each member is regulated in pulling; when needing insulation or protection; can spur each stay cord (each two-way garden arc double-head arrow in Fig. 3) enters the water heater rotation in the window frame 27; shut simultaneously and with upper and lower protecting cover; a feature is again, and upper and lower water pipe connects with flexible pipe 29,30 (for example rubber, plastic tube etc.).All do not influence the unimpeded of its water route and sealing for each member position variation.
