Abstract

The utility model provides a shell and tube heat changer type domestic solar heater which is the reasonable improvement of the existing solar heater in structure and material adoption according to national condition of China and satisfies the precondition of operating requirement. The heat collector is provided with a hollow tube which has three-way, etc parts on the end of the tube and is connected with upper lower collecting tubes. The utility model leaves out a circulation water tank and a complement water tank and has the advantages of low cost and easy maintenance which can efficaciously ensure empty solarization of the heat collector not to corrupt. The utility model can product 50-70 kg hot water of 40-70 DEG C temperature everyday to supply the use for 4-5 household.

Description

Shell and tube heat changer type domestic solar heater

The utility model relates to the energy utilization technology field, is a kind of domestic solar water heater.

In the last few years, the development and use of solar energy were paid attention to by people quite, and wherein the application technology with solar water heater is the most ripe again.The many provinces and cities of China are all making great efforts to promote this technology.Yet because cost is high, fetch long price makes this useful application technology slowly be difficult to promote, be popularized for most of families.The shell and tube domestic solar water heater who the utility model proposes, set out according to the national conditions of China exactly, in line with least cost, satisfy the spirit of general operational requirement, on structure, technology and the selection of material, rationally improve, reduce cost significantly, move towards each average family in the hope of making solar water heater.

The utility model is different from domestic existing tube-sheet type, the solar water heater of form such as corrugated, flat box type, the closing-sunning type water heater that also is different from Japan, it has saved cyclic water tank and water supply tank, thereby simplify the structure greatly, its primary structure has comprised heat collector and incubator, transparent cover plate and the shell of being made up of comb, upper header, lower collector pipe, delivery port, water inlet.Heat collector put the insulation casing in, on seal transparent cover plate; Incubator is surrounded by housing outward; The comb of heat collector is closely arranged by several ageing-resistant plastics heavy caliber hollow tubes and is formed, upper header is identical with the lower collector pipe form, with three deferents be connected with the pipe joint at the two ends of each comb (be convenient to maintenance and assembling), upper header one end has delivery port (going out hot water), lower collector pipe one end is a water inlet (advancing cold water), and outside the entery and delivery port position housing 10.

Accompanying drawing is the utility model structural representation (local cross-sectional) figure

Accompanying drawing is the utility model collector structure schematic diagram

Among the figure: 1 is that comb, 2 is that upper header, 3 is that lower collector pipe, 4 is that water inlet, 5 is that delivery port, 6 is that three-way pipe, 7 is that pipe joint, 8 is that incubator, 9 is that transparent cover plate, 10 is a housing.

Daylighting area of the present utility model is about 0.9 square metre, and water capacity is 60 kilograms.

Fill it up with cold water from water inlet pipe when using the utility model, through the heat absorption of solar radiation heat collector comb, cold water is heated, when needs use hot water, as long as open water inlet, cold water is gone into, and delivery port hot water then flows out naturally, thereby the utility model is when using hot water, then also add cold water simultaneously, so can not occur causing empty solarization of heat collector to damage phenomenon,, be convenient to assembling and maintenance again because of on structure and technology, having used part and adhesive bonding techniques such as three deferents and pipe joint owing to forgetting to add cold water; And the utility model has saved cyclic water tank and outer water tank, adopts plastic processing to become the heat absorption comb, makes simply, and is with low cost, is convenient to produce in enormous quantities and penetration and promotion rapidly.

The utility model can be produced 40-70 ℃ of water temperature daily, and the hot water of 50-100 kilogram can satisfy family's every day in summer (shower 1-2 time) of general 4-5 mouth, a shower of everyone jede Woche in spring and autumn and winter the kitchen warm washing water.

To sum up, the utility model is to be suitable for the domestic solar water heater that (about 100 yuan) simple in structure, with low cost of China's national situation have good result of use.
