Solar energy vacuum heat collection tube

The utility model provides a glass -ceramic solar energy vacuum heat collection tube that can prevent the fried pipe of solar energy vacuum heat collection tube. It is under the condition of using transparent quartz glass as the outer tube, and through the metal stationary blade is fixed and inlet outlet locates and the pottery conduct inner tube of the outer pipe joint of transparent quartz glass, this is with firm the fixing in transparent quartz glass outer tube of ceramic inner tube. Because of porcelainous high temperature resistance ability is good, anti cold thermal shock resistance properties is strong, and coefficient of heat conductivity is not high again, and these characteristics will guarantee effectively that solar energy vacuum heat collection tube stably works and fried pipe under cold and hot impact condition. 种能够防止太阳能真空集热管炸管的玻璃陶瓷太阳能真空集热管。它是在以透明石英玻璃为外管的条件下，通过金属固定片固定和进出水口处与透明石英玻璃外管接合的陶瓷作为内管，这将陶瓷内管牢固的固定在透明石英玻璃外管内。因陶瓷的耐高温性能好，抗冷热冲击性能强，导热系数又不高，这些特性将有效保证太阳能真空集热管在冷热冲击条件下稳定工作而不炸管。
