本文首先研究了真空钎焊条件对热管性能的影响，进而在最优条件下制作了热管及热管式真空集热管，并和市场上销售的产品进行了性能比较。在我们的实验条件下，最佳的热管真空钎焊工艺为：钎料成分为 BAg44CuZn 钎料，钎焊真空度为5×10-3 Pa ，真空钎焊功率为7.6 kW ，钎焊间隙为0.08 mm。采用此工艺制作的热管其老化后的性能几乎不变，远优于市场上销售的热管，组装成热管式真空集热系统以后，其集热性能也比现有产品大为提高。

In this paper , the effects of different process parameters on properties of heat pipes were analyzed . Then heat pipes and vacuum collector tubes with heat pipes were made under optimal conditions . The performance of our products was compared with which sold in the market . The results show that the best quality is obtained when using BAg44CuZn as solder;vacuum degree is 5 × 10-3Pa; welding power is 7 . 6kW; welding distance is 0 . 08mm . The performance of the heat pipes we make is nearly unchanged after aging , which is far better than that sold in the market . The performance of heat-collecting system assembled with our heat pipes is also superior to that of products sold in the market .
