Abstract

The utility model provides a device of sun heat energy is collected in desert area relates to renewable energy utilization technical field, including burying the hot exchange pipe in the desert, be provided with the fin that the spiral surrounded on hot exchange pipe's the outer pipe wall, the round heat -conducting plate is established to every 20 -30 centimetre ring on hot exchange pipe's the outer pipe wall, heat -conducting plate round ring even is at least established threely. The utility model provides a device of sun heat energy is collected in desert area can collect the heat energy in the desert and utilize to carrying away heat energy through heat exchange medium, in the time of the heat exchange of this heat energy receiving arrangement recurrence, can also fixing the sand in the desert, avoid under the action of the wind, the sand moves, and the heat energy receiving arrangement who results in burying in the sand directly comes out.

Description

A kind of device collecting solar thermal energy in desert area

Technical field

The utility model relates to renewable energy utilization technical field, is specifically related to a kind of device collecting solar thermal energy in desert area.

Background technology

Enter 21 century, the shortage of fossil energy and the scarcity of coal resources, cause again the anxiety of electric power resource simultaneously, and thermal power generation discharge throughout various places, motor vehicle exhaust emission and this three large discharge of industrial pollution impel the sharply deterioration of air ambient, and the serious safety that threaten national energy and national quality of air environment of depending on for existence.This situation has arrived the stage of solution.

So make full use of reproducible solar energy source, wind resource and underground energy, and convert it into the new forms of energy of clean environmental protection, become the task of top priority of commonwealthn.But actual conditions are also pessimistic, such as, solar energy source and wind resource utilize present situation, though there is certain improvement effect remote.

In desert area, Intensity of the sunlight is large, and the prospect that solar energy source can develop is boundless, and the desert of sheet is exactly natural heat collecting field, how effectively to be used by the heat energy in desert, is the key utilizing solar energy in desert area.And in prior art, also lack this type of technology.

Utility model content

The purpose of this utility model is the defect existed for prior art, proposes a kind of device collecting solar thermal energy in desert area.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of device collecting solar thermal energy in desert area, it is characterized in that: comprise the heat-exchange tube be embedded in desert, the outer tube wall of heat-exchange tube is provided with the fin of spiral surrounding, the outer tube wall of described heat-exchange tube establishes a circle heat-conducting plate every 20-30 centimetre of ring, and described heat-conducting plate one encloses at least uniform ring and establishes three; Described heat-exchange tube coiled coil, one end of heat-exchange tube is liquid feeding end, and the other end is outlet end.

Described heat-exchange tube be arranged many in parallel, the two ends of many heat-exchange tubes connect respectively by collecting pipe, wherein the collecting pipe of one end is liquid feeding end, the collecting pipe of the other end is outlet end, heat exchange medium flows into from liquid feeding end, enter into each heat-exchange tube respectively, absorb the heat in sand bed, then flow out from outlet end.

The shape of heat-exchange tube coiled coil is imbedded in sand bed, good stability, and remarkable to the fixation of sand bed, collecting efficiency is high.

The length of described heat-conducting plate is 8-10 centimetre, the surface of described heat-conducting plate is provided with corrugated projection, heat-conducting plate inserts in sand bed, not only more large-arealy can contact with sand, increase heat exchanger effectiveness, can also stable for heat-exchange tube is fixed in sand bed, fixation can be played to sand simultaneously, avoid sand to flow, and then avoid heat-exchange tube to be out of shape in sand bed, or exposed more than sand bed.

The described heat-exchange tube degree of depth imbedded in desert is 10-20cm, upper strata sand is under being exposed to the sun of the sun, temperature can reach 60 °-70 °, heat exchange medium is passed in heat-exchange tube, with the sand generation heat exchange of high temperature, heat exchange medium temperature flows out after raising, and be used to heat energy, heat exchange medium can select water.

Described heat-exchange tube imbeds the position in desert, has 35 °-45 ° domatic on the sunny side.

The beneficial effects of the utility model are:

The device collecting solar thermal energy in desert area that the utility model provides, thermal energy collecting in desert can be got up be used, and by heat exchange medium, heat energy is transferred out, while there is heat exchange again in this heat energy receiving system, the sand in desert can also be fixed, avoid under wind-force effect, sand moves, and causes the heat energy receiving system be embedded in sand directly to come out.
