Description
Technical field
The utility model relates to a kind of all-glass heat tube type evacuated solar collector tube (hereinafter to be referred as the heat pipe-type thermal-collecting tube), belongs to the solar energy utilization technique field.
Background technology
In application number is 200420050936.7 patent application, propose in order to make heat transfer efficiency good, and reduce the pressure in the confined space, the volume of heat pipe-type thermal-collecting tube transfer working medium in heat is 1/500～1/150 of a confined space volume.Through calculating and experiment, when empty the solarization appears in thermal-collecting tube (anhydrous in the vacuum tube collector water tank), temperature can reach 200 ℃ in the pipe, or even 250 ℃, according to above-mentioned working medium amount, at this moment the pressure limit in the heat pipe-type thermal-collecting tube is 3.6～12 atmospheric pressure, and the glass safety working strength of common used heat pipe-type thermal-collecting tube is exactly 6 atmospheric pressure, add that glass tube itself also has certain machining stress, so this working medium weight range is bigger than normal, just 1/300～1/150 this working medium amount volume ratio scope in use is easy to cause having the danger of bombing, safety inadequately when sky shines.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned heat pipe-type thermal-collecting tube, to make a kind of more safe and reliable all-glass heat tube type evacuated solar collector tube.
The utility model comprises complete glass vacuum sun thermal-collecting tube, butt tube, confined space and heat-transfer working medium, it is characterized in that the volume of heat-transfer working medium accounts for the volume ratio of glass heat pipe confined space volume greater than 0.03%, less than 0.1%.
Said heat-transfer working medium is 0～30% aqueous solution of propylene glycol.
Said heat-transfer working medium is 0～20% inorganic acid, saline solution.
Also one or more metal supporting rings can be arranged vertically on the inner glass tube outer wall of said complete glass vacuum sun thermal-collecting tube.
The utility model has the advantages that: because the amount of intraductal heat transfer working medium is few, the maximum pressure that can limit confined space is no more than 5 atmospheric pressure, guarantees that glass is in the pressure range that can bear; Increased metal supporting rings, the structural strength of heat pipe-type thermal-collecting tube is improved, not fragile in installation and transportation.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment one.
Fig. 2 is the specific embodiment one water temperature and graph of a relation constantly when test.
Fig. 3 is the structural representation of the specific embodiment two.
The specific embodiment
Fig. 1 has provided first embodiment of the present utility model, and wherein 1 is complete glass vacuum sun thermal-collecting tube, and the 2nd, inner glass tube, the 3rd, butt tube, the 4th, confined space, the 5th, heat-transfer working medium.Calculating combines with experiment according to theory, is guaranteeing also will to guarantee its heat exchange property simultaneously under the heat pipe-type thermal-collecting tube prerequisite safe in utilization.In the present embodiment, the volume of working medium and the volume ratio of confined space are 0.08%, if the size of confined space is φ 34 * 1600mm, then the working medium amount is 1.2ml, employing be pure water.By calculating, when temperature reached 250 ℃ in pipe, the pressure in the pipe can not surpass 4 atmospheric pressure, therefore used as safe as a house.The butt tube of present embodiment partly inserted in 1.3 liters the water-filled test water tank, under the solar irradiation, average ambient temperature is-4.5 ℃ in the winter time, and the average water temperature in the water tank is seen Fig. 2 with relation curve constantly.Just as can be seen, the heat transfer property of present embodiment is good from figure, and the amount that working medium is described is can satisfy fully to conduct heat to require.
If the aqueous solution with organic matter or inorganic acid, salt, aqueous solution of propylene glycol as 0～30% or 0～20% inorganic acid, saline solution, inorganic acid, salt can be composition or the composition of potassium bichromate, potassium sulfate, ammonium sulfate and ammonium phosphate or the compositions of potassium bichromate, potassium sulfate, sulfuric acid, phosphoric acid, ammonium sulfate and ammonium phosphate of potassium bichromate, potassium sulfate, sulfuric acid and phosphoric acid, can also play antifreeze effect.
Fig. 3 has provided another embodiment of the present utility model, and wherein 1 is complete glass vacuum sun thermal-collecting tube, and the 2nd, inner glass tube, the 3rd, butt tube, the 4th, confined space, the 5th, heat-transfer working medium, the 6th, metal supporting rings.The volume of heat-transfer working medium and the volume ratio of confined space are 0.05%, working concentration is the aqueous solution of 15% potassium bichromate, potassium sulfate, sulfuric acid and phosphoric acid compositions, the proportional quantity of several inorganic acids, salt is 1: 29: 19: 14, present embodiment is identical with the hot property of embodiment one, can also reduce freezing point, play antifreeze effect.In addition, because the development trend of thermal-collecting tube is that pipe is done longer and longer now, the flexible deformation of pipe self is also more serious, therefore in the process of transportation and installation, is easy to damage thermal-collecting tube.After having installed metal supporting rings additional, just can reduce distortion, in the process of transportation and installation, the heat pipe-type thermal-collecting tube is just not fragile yet.Use a metal supporting rings in the present embodiment, placed in the middle vertically.
The number of metal supporting rings can also be used two or more according to the physical length of pipe, axially evenly distributes along thermal-collecting tube usually.
