Abstract

PURPOSE:To prevent the outer tube from sustaining damages when heat collector is inserted into the outer tube of the heat collector by decreasing the diameter of a resilient support less than the inner diameter of the outer tube, melting the bonding agent by heating, after inserting the heat collector into the outer tube by maintaining the diameter decreased state by the adhesion of the bonding agent so as to press-fit the support onto the inner surface of the outer tube. CONSTITUTION:Before inserting a heat collector 2 into an outer tube 1 made of glass, the diameter of a spring member 3 is decreased less than the inside diameter of the outer tube 1 as shown in Fig. (a), and a bonding agent 6 consisting of a solder having a melting point of 180-220 deg.C, for example, is applied to the end part of the spring member 3, and melt-hardened to maintain this diameter decreased state. Thereafter, as shown in Fig. (b), the heat collector 2 is inserted up to a predetermined position. In this inserting step, the contact between the spring member 4 and the outer tube 1 is little, and the damage of the outer tube are decreased. When the bonding agent 6 is heated to approximately 100 deg.C (since the spring member 3 has an expanding force, it is not required to completely melt the bonding agent), the spring member 4 expands by the resilient force of the spring member itself and is press-fitted to the inner face of the outer tube 1 as shown in Fig. (c), and the heat collector 2 is fixed to a predetermined position of the outer tube 1.
