Description

Sealing structure of flat-plate solar collector

Technical Field

The utility model belongs to the technical field of the solar photothermal, in particular to flat plate solar collector's seal structure.

Background

Since centuries after the industrial revolution, the main energy sources used in the world are fossil energy sources such as coal, oil and natural gas. With the improvement of the industrialization degree, the energy consumption is gradually increased, the total amount of fossil energy on the earth is limited, and the energy crisis is inevitable. According to the related conjecture of the international energy agency: in the next 25 years, the total demand of world energy will increase by about 1 time. Oil will be depleted in approximately 2050 years;the total natural gas amount is estimated to be 1.318-1.529 x 10¹¹m³If the annual production is 2.3X 10⁹m³Will be exhausted within 57-65 years; the total coal amount is estimated to be 5.6X 10¹¹t, can be used for 169 years. From this point of view, fossil fuels are exhausted in the near future, and moreover, the fossil fuels have many negative effects in the using process.

Renewable energy and clean and environment-friendly energy are developed, a green concept is advocated, solar energy is mainly used at present, and the solar energy-saving solar: (1) the coverage is wide, the solar energy resources are everywhere in the global range, whether on land or sea, high-altitude or flat ground, south or north, the utilization is convenient, and the exploitation and transportation are not needed; (2) the total energy is large, the total emission quantity reaching the earth surface every year is equivalent to 130 trillion tons of coal, and the energy is one of the largest total energy sources available at present; (3) the cleanliness is high, and no environmental pollution is produced in the solar energy collection process, so that the solar energy collection device is one of the cleanest energy sources.

At present, with the continuous progress of scientific technology, new materials and new technologies are developed day by day in China, a batch of new equipment is cultivated and promoted, and a solid technical support is provided for the application of the technology. The flat-plate solar collector is in outdoor working process, and "steam problem" is the chronic disease of flat-plate solar collector trade always on the heat collector glass, and steam can reduce glass's luminousness on the one hand, influences the heat absorption efficiency of heat collector, and on the other hand steam accumulates to become the drop of water, can drip on flat-plate solar collector's heat absorption membrane, causes the corruption damage of heat absorption membrane, finally can lead to the heat absorption efficiency and the life of heat collector. On the other hand, moisture on the glass of the heat collector can also affect the appearance of the product, and cause adverse effects to customers. The main reasons for the water vapor on the glass of the flat plate collector are as follows: the sealing structure of the flat plate collector is not good, the structural design of the common sealing strip is unreasonable, and the material selection also has a miszone, so that rainwater permeates into the flat plate collector from the joint of the glass and the outer frame of the collector under the outdoor working state of the flat plate collector, and the rainwater is changed into water vapor to be attached to the glass under the condition of high temperature inside the rainwater collector.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model aims to provide a sealing structure of a flat-plate solar collector.

In order to achieve the above objects and other related objects, the present invention provides a technical solution: a sealing structure of a flat-plate solar collector comprises glass and an outer frame; an annular sealing strip is arranged between the glass and the outer frame, the sealing strip is provided with a groove, the inner sides of two groove walls of the groove are provided with a plurality of first annular protruding parts extending towards the groove, and the first annular protruding parts are abutted against the glass; and a plurality of second annular protruding parts extending outwards towards the groove are arranged on the outer sides of the two groove walls of the groove, and the second annular protruding parts are abutted with the outer frame.
