Description

Sheet type solar water heater

One, technical field

The utility model relates to a kind of solar water heater, and a kind of specifically absorber plate is the sheet type solar water heater of thin slice.

Two, background technology

Present stage, common solar water heater had three kinds of fundamental types, and the one, traditional is flat, and its weak point is that heat absorption efficiency is on the low side, and is not too freeze proof; The 2nd, electron tubes type, its shortcoming is that cost is higher, not too anti-hail; The 3rd, the auxiliary electrical hot type, its defective is inconvenience is installed, and has hidden danger safe in utilization, needs power consumption, increases use cost.

In addition, since China implements patent system, the technical products application of relevant solar water heater national patent also a lot, not following thousand kinds, this illustrates that this type of technology obtains a lot of people's concern and innovation, and these achievements of technology innovation have greatly been enriched diversity and practicality that technology realizes.Certainly its quality, quality also are difficult to comment on one by one.

From the economy of technology, people always wish to buy solar water heater low price, low, safe and reliable, the long service life of use cost.

From the effectiveness of technology, require the heat absorption efficiency height, simple in structure, convenient for installation and maintenance.

For this reason, the flat solar water heater mainly solves by setting up the heat absorption fin, but this mode of continuing to use does not for a long time have the people and proposed doubt, in addition, the ability that the hot water circulating pipeline design does not have the worry about hot-fluid independently to quicken to circulate yet improves, moreover freeze proof means are not considered to solve from structural design.These problem the utility model are all given and solution by structural design.

By thin slice design, columnar water is heated become stratum water and is heated, cancelled the heat absorption fin, directly increased heating surface area; By stairstepping hot-fluid pipe design, eliminate the existence in recessive thermal resistance zone as far as possible, promoted the lifting of hot-fluid circulation ability, directly improved the thermal efficiency; Its expansion rate was approximately 10% of original volume after water was endured cold and frozen, and was oval with pipe design, was very beneficial for freeze proof realization.

The utility model adopts new structural design, makes the flat solar water heater obtain innovation, economizes on resources, and promotes energy utilization rate, gives technical support to further developing of flat solar water heater, benefits the whole mankind.

Three, summary of the invention

Goal of the invention of the present utility model just provides a kind of thermal efficiency and improves, and frost resistance is significantly improved, sheet type solar water heater with low cost.

Realize that the technical solution of the utility model is such: sheet type solar water heater, structure is that running water water inlet pipe 1 is installed in the into top of water control cabinet 2, water control valve is equipped with in its inside, its underpart has cold water inlet 3 to feed the bottom of heat collection water tank 4, be provided with gland steam exhauster 5 at the top of heat collection water tank 4, portion is provided with hot water outlet pipe 6 on the upper side, feed hot water inlet pipe 7 and cold water outlet pipe 11 in the bottom, the be connected in parallel top water pipe of absorber plate 9 of hot water inlet pipe's 7 stairsteppings, the be connected in parallel bottom water pipe of absorber plate 9 of cold water outlet pipe 11 levels, afterbody at cold water outlet pipe 11 is provided with drainpipe 10, and control valve is installed on it, and absorber plate is positioned in the incubator 8.

Wherein, absorber plate is slice structure, the space length between its inner chamber levels is 3 millimeters to 20 millimeters, the bottom is a waveform emboss pit 12, intake-discharge pipe is equipped with in top and the bottom.The installation number of absorber plate can optionally be decided, and area greatly then received heat is big.

The planform of absorber plate is trapezoidal.Help the autonomous acceleration circulation of hot-fluid.

The cold water inlet 3 that relates to, hot water inlet pipe 7, drainpipe 10, cold water outlet pipe 11 its structures are inclined to one side ellipse.Help freeze proof since water freezing after its expansion rate be about 10%, so can swollen broken pipe.

Absorber plate is made with flake aluminum.But the rolling injection-compression molding greatly reduces cost of material, production cost.

The beneficial effects of the utility model are: product cost is whole to descend, and is easier to popularize energy savings; The thermal efficiency improves significantly, can improve more than 10% on the basis of the dull and stereotyped water heater of existing plain edition; Frost resistance improves, and adapts to different environment for use in all parts of the country more, helps the popularization and application of solar energy; Do not consume the precious metal material, economize on resources.
