Description

Pipe is semicircular vacuum heat collection pipe in a kind of

Technical field

The utility model relates to a kind of interior pipe and is semicircular vacuum heat collection pipe, is that semicircle, outer tube can be the semicircle solar water heater that circular vacuum heat collection pipe is formed that also can be by interior pipe specifically.

Background technology

Along with improving constantly of living standards of the people, as with the closely-related articles for use of people's lives---water heater enters huge numbers of families just more and more.Present water heater mainly contains gas heater, electric heater and solar water heater etc.Because gas heater in use, the personal accident accident can occur, so country has required gas heater to install and forced the waste discharge device; Electric heater since its heating components and parts soak all the time and be embedded in the water, in case the electrical heating components and parts burn out the security incident of will leaking electricity, and the thermal efficiency of electric heater is low; Although work out microwave water-heater in person,, for various reasons, do not finish exploitation so far yet.In recent years, the solar water heater technology has had the progress of arriving very much.Although along with continuous advancement in technology, the thermal efficiency of solar water heater is greatly improved.But it absorbs the water heater that solar energy heats because it is utilization after all, so, be subjected to very much the influence of weather.

Summary of the invention

The purpose of this utility model is at existing solar water heater, under equal conditions, reaches the purpose that improves the thermal efficiency.

The purpose of this utility model realizes by following measure:

With the utility model a kind of in pipe is the solar water heater that semicircle vacuum heat collection pipe is formed, mainly by: pipe was formed for semicircular vacuum heat collection pipe and water inlet pipe and water outlet pipe in support, attemperater and the utility model were a kind of.Pipe was that semicircular vacuum heat collection pipe and attemperater are rack-mount in the utility model was a kind of, and pipe linked to each other with attemperater for semicircular vacuum heat collection pipe in the utility model was a kind of, and attemperater is provided with intake-outlet, for being installed into outlet pipe

Pipe was semicircular vacuum heat collection pipe in the utility model was a kind of, have basic different with existing vacuum heat collection pipe, the inner and outer pipe of existing vacuum heat collection pipe all is circular, and vacuum heat collection pipe inner tube of the present utility model is semicircle (seeing accompanying drawing), outer tube also can be the same with interior pipe, be semicircle, also can be circle.The heat-absorbing material (seeing accompanying drawing) that can fully absorb solar energy is coated in the bottom of pipe in semicircle.The part in space is evacuated between interior pipe and the outer tube, is semicircular vacuum heat collection pipe thereby make it to become a kind of interior pipe of the utility model for the interior pipe of semicircular vacuum heat collection pipe solar water heater.

By the computing formula of circumference, know this diameter of a circle length, be 1/3.14th of this circumference.If we are that 50mm, length are that pipe serves as that circle and semi-circular vacuum heat collection pipe are example in the 1500mm with diameter equally, the girth that gets this pipe circle is 157mm, and the area of this semicircle is onesize diameter circular inner tube surface amasss half.When the interior pipe of vacuum tube be coated with can fully absorb the material of solar energy after, sunshine also just can't penetrate this layer material.That is to say that its area that effectively absorbs solar energy has only the length of 157mm * 1500mm/2 pipe to equal 1177.5 square centimeters, and this solar radiation effective area that is subjected to of 1177.5 square centimeters is 750 square centimeters of twices that effectively are subjected to the solar radiation area to add heat of semicircle interior pipe, and to finish the same heat that adds, the sunkissed effective area of circular interior pipe should be 1500 square centimeters.

Because, diameter of inner pipe is similarly the round tube of 50mm and compares with semicircular vacuum heat collection pipe, under same condition, finish the same heat that adds, in pipe be subjected to the effective irradiated area of sunlight to lack 322.5 square centimeters for circular vacuum heat collection pipe than effective irradiated area of semicircle vacuum heat collection pipe, so, under same time, condition, finish the same heat that adds, interior pipe is the temperature of water in the semicircle vacuum heat collection pipe, be higher than the temperature of water in the circular vacuum heat collection pipe.And then, interior pipe be semicircular vacuum heat collection pipe with in the attemperater, the time of equal water yield heating will be the vacuum heat collection pipe of circle faster than interior pipe.

In addition, interior pipe is the heat absorbing coating amount of semicircle vacuum heat collection pipe, has only 1/3.14th of same diameter circular vacuum tube.Like this, not only saved the cost of heat absorbing coating, and, the cost of vacuum tube also saved.

After the empty set heat pipe of taking seriously absorbs the radiation of the sun, water in the vacuum heat collection pipe is heated, and then the density that is heated water is diminished, because the temperature of water has the temperature difference in the temperature of the interior water of vacuum heat collection pipe and the attemperater, so the water in the attemperater will sink, and the water in the vacuum heat collection pipe will make progress, it is mobile that thereby water in the vacuum heat collection pipe and the water in the attemperater form, the heating of the water in the attemperater the most at last.
