PURPOSE:To improve durability by inserting an end of a heat pipe which is contained inside a glass envelope into an end of an outlet pipe which is arranged on the same side of the envelope, and slidably supporting on the inner wall through a support member having a heat insulating capability. CONSTITUTION:In a solar heat collector of vacuum tube type in which a straight heat pipe 1a is housed in a vacuum glass envelope 2b, the end of a heat pipe contained inside the glass envelope 2b is inserted into the end of an outlet pipe 9 which is arranged on the same side of the envelope 2b. And, it is slidably supported on its inner wall through a support member having a heat insulating capability such as a coil spring. In this manner, despite a large difference in the thermal expansion between the heat pipe 1a and the envelope glass tube 2b, the envelope glass tube will not be damaged. Therefore, a solar heat collector having an excellent durability can be obtained. |
