Problems solved by technology

The second-generation product overcomes the shortcoming of the first-generation product that is easy to be damaged by freezing, and is currently a more commonly used heat-collecting element, but it still has some shortcomings, such as in extreme working conditions (sunshine in the sun, no water in the water tank) At this time, the temperature of the heat pipe is as high as 250-

Embodiment Construction

[0011] see figure 1 , the utility model is composed of a glass heat pipe 1 and a glass outer pipe 2, wherein the heat pipe is composed of an evaporation section 1-2 and a condensation section 1-1, the evaporation section is set in the outer pipe, the condensation section is located outside the outer pipe, and the outer pipe and the heat pipe are two are melted. Vacuum is drawn between the heat pipe and the outer pipe as well as in the heat pipe, and the outer wall of the heat pipe is attached with a high-temperature selective heat-absorbing coating, which can make the heat pipe have a higher absorption rate and a lower emissivity, and the heat pipe is filled with working fluid. The gist of the invention is: to change the state of the working fluid so that it can be converted into a vapor phase when it reaches a certain critical temperature. In this way, when the temperature continues to rise, the pressure rises according to the law of the vapor phase, not the law of the vapor...

Abstract

It is in vacuum state between glass heat pipe and glass outer tube as well as inside glass heat pipe. Fusing seals both of heat pipe and outer tube. Heat absorption coating is coated on external wall, and working medium is filled inside heat pipe. Quantity of working medium filled is 0.1-0.5%V, where V is cubage of heat pipe. Based on theory of applied thermodynamics, quantity of working medium is selected scientifically. When temp reaches a critical temperature, all working medium is turned to vapor phase. If temp rises continuously, the pressure is raised according to rule of vapor phase, reducing pressure inside the heat pipe under high temp so as to solve issue of cracking glass heat pipe caused by solarizing empty glass heat pipe. Adsorption material is added inside heat pipe in order to ensure restarting glass heat pipe rapidly.

Description

technical field [0001] The invention relates to an element used in a solar energy device, in particular to an all-glass vacuum heat collecting tube which does not burst under the sun, and belongs to the technical field of heating equipment. Background technique [0002] Utilizing solar heating for heating is an advanced technology widely adopted in recent years. Although the structure of various solar water heaters is not the same, the key technology is to rely on the heat collector to fully absorb the energy of sunlight, convert it into heat energy, and heat the water source for use. Vacuum heat collecting tubes are commonly used heat collecting elements on solar water heaters. Its first-generation product consists of an inner tube and an outer tube. The space between the two tubes is evacuated, and the outer wall of the inner tube is coated with heat-absorbing materials. Water flows through the inner tube, and the water is heated by absorbing solar radiation on the outer ...
