Abstract
The utility model relates to a narrow slit vacuum glass cover plate for solar heat collectors, which is formed from an upper and a lower glass plates and a supporting column which is arranged between the upper and the lower glass plates. The circumference of the narrow slit between the upper and the lower glass plates is welded by low-melting glass welding flux, and the narrow slit is evacuated by means of a vacuum orifice. Because the utility model is provided with the high vacuum interlayer, the utility model has very high convection and heat transferring thermal resistance and has good characteristics of heat insulation and thermal insulation. When the utility model is used as a cover plate of a solar heat collector, the solar heat collector can work under the condition of low environmental temperature and low solar radiation intensity in winter, so the time of using the solar heat collectors per year is extended greatly, and simultaneously, the heat radiation of the heat collector at night can be reduced greatly.
Description
The utility model belongs to energy-conservation and field of solar energy utilization, particularly a kind of transparent cover plate of solar thermal collector.
At present, at solar energy heat utilization field, main use two kinds of solar thermal collectors are arranged.A kind of is with the glass-faced flat type solar heat collector of common plane; Another kind is the all-glass vacuum tube type solar thermal collector.All-glass vacuum tube type solar thermal collector dominate particularly.Because flat type solar heat collector is when environment temperature is low, collecting efficiency is very low, and the hot water that meets use can not be provided.Its reason mainly is that the thermal resistance of ordinary plate glass is too little, with its cover plate as heat collector, by the glass cover-plate dispersed heat too big due to.But flat type solar heat collector has the reliability height, the manufacturing of water tank is required advantages such as low.The shortcoming of all-glass vacuum tube type solar thermal collector is: (1) all-glass vacuum tube all adopts the microcirculation formula, and an end of opening inserts heat collection water tank, and an end that seals places the below of water tank.Therefore,, all there are every year a large amount of silts to sink to the pipe end, make the true use length of vacuum tube dwindle year by year, lost thermal-arrest when situation is serious in 3 years fully and render a service in the bad place of water quality; (2) vacuum tube is communicated with water tank, therefore, the solar water heater of what vacuum tubes is arranged, and what vacuum tube sockets water tank just must have, and this manufacturing to water tank has proposed very high requirement.In use, even there is a pipe to damage, whole system just can not be used, and this is extremely disadvantageous to big system; (3) there is certain distance that sunlight is not fully utilized between the tube and tube of electron tubes type heat collector, causes the sunlight loss, make the electron tubes type heat collector be subjected to very big restriction.
The purpose of this utility model is to overcome the shortcoming of above-mentioned solar thermal collector, and a kind of running temperature height, collecting efficiency height, the low solar thermal collector narrow slit area vacuum glass cover-plate of heat radiation are provided.
For achieving the above object, the solution that the utility model adopts is: be provided with three support columns between upper glass plates and the lower-glass at least, side welded seal and be provided with the mouth of bleeding between upper glass plates and the lower glass plate constitutes vacuum chamber between upper glass plates and the lower glass plate.
The thickness of upper glass plates of the present utility model and lower glass plate is 2～5mm, the Breadth Maximum of support column is 0.1～8mm, highly be 0.2～1mm, the distance between a support column and the adjacent support column and the distance at support column and upper glass plates or lower glass plate edge are 2～6cm.
Support column of the present utility model is to make with the clear glass that metal material is made also available organic or inorganic material.
The utility model is 0.1～0.3mm with the Breadth Maximum of the support column that solid metal material is made, and the Breadth Maximum of the support column made from the clear glass of organic or inorganic material is 0.1～8mm.
Owing to having the high vacuum interlayer, the utility model has very high convection current and heat transfer resistance, thereby has a well heat insulation and heat preservation property, thereby work under the condition that environment temperature is low and intensity of solar radiation is low in the winter time, prolonged the service time in solar thermal collector every year greatly, greatly reduced the heat radiation of heat collector simultaneously at night.
