Conventionally, as shown in FIGS. 6 and 7, the heat collecting plate and the heat collecting tube of this type of solar heat collecting device are fixed by fitting the heat collecting tube 3 into the groove 2a provided in the heat collecting plate 2, and then inserting the heat collecting tube 3 into the groove 2a provided in the heat collecting plate 2. Generally, the center portion 4 is fixed by caulking with the same strength. Note that 1 is a heat collecting plate assembly. However, with this structure, it is not possible to release the thermal stress caused by the difference in thermal expansion and contraction between the heat collecting plate 2 and the heat collecting tube 3, so the heat collecting plate 2 causes warping and waving, which not only makes the appearance unsightly, but also makes the heat collecting plate This may lead to a serious problem that the assembly 1 of the heat collecting pipe and the heat collecting pipe is destroyed. By the way, if the heat collecting plate 2 is a steel plate and the heat collecting pipe 3 is a copper pipe, on a clear day the
800Kcal/m 2 h solar radiation, about 250℃ when the heat collection tube is empty, about 220℃ when cold water of about 30℃ is circulated to the heat collection tube
If there is a heat shock of 1,000 deg, there will be a difference in thermal expansion of about 2 mm between the heat collecting plate 2 and the heat collecting tube 3, which will be about 1000 deg.
A thermal stress of Kg occurs. In addition, as the heat collecting plate 2 and the heat collecting pipe 3 repeat thermal expansion and contraction, the sixth heat collecting plate 2 and the heat collecting pipe 3
There is a groove-like scratch on the P part (both ends of the heat collecting plate 2) shown in the figure due to the cut end of the heat collecting plate 2, which causes the problem of a decrease in the wall thickness of the heat collecting tube 3, and at the same time prevents thermal stress from escaping. Therefore, the connection may become loose, causing the heat collecting plate 2 to rotate with respect to the central axis of the heat collecting tube 3, resulting in a problem that an appropriate receiving angle for sunlight cannot be maintained.

This invention achieves the above object by coaxially arranging a heat collecting plate through which a heat medium flows inside a vacuum glass tube, and fixing a heat collecting plate extending in the radial direction of the glass tube to this heat collecting tube. In the thermal device, a heat collecting tube is fitted into a groove provided on the axial center line of the heat collecting plate, and the heat collecting plate and the heat collecting tube are joined by caulking more strongly at the center than at both ends in the axial direction. This is achieved by a solar heat collecting device that is characterized by: It is further preferable that the openings of the grooves are widened in the axial direction so that the end faces of the heat collecting plate do not come into contact with the heat collecting pipes at both ends of the joint between the heat collecting plate and the heat collecting pipe.

This invention will be explained below with reference to drawings showing embodiments. Figures 1 to 4 are drawings showing an embodiment of this invention, with Figure 1 being its front view and Figure 2 being its B.
-B sectional view, FIG. 3 is a CC sectional view, and FIG. 4 is a DD sectional view. In the figure, the heat collecting plate 2 and the heat collecting pipe 3 are strongly caulked by a press die at the center part 4, and both ends 5 are caulked weaker than the center part 4 by devising a press die, creating a difference in the caulking strength. . In such a configuration, even if a heat shock of approximately 220°C occurs, the central portion 4 becomes the neutral point of thermal expansion and contraction, and the caulking force is weak at both ends 5, so the heat collecting plate 2 and the heat collecting tube 3 slip, causing the heat collecting to occur. Heat plate 2 and heat collecting pipe 3
Almost no thermal stress occurs during this period. As a result, the heat collecting plate 2 does not warp or wave. and,
Since the caulking force at the central part 4 is strong, the heat collecting plate 2 and the heat collecting tube 3 are tightly connected at this part, which is the neutral point of thermal expansion and contraction, and the connection will not loosen due to thermal expansion and contraction, and the heat collecting plate will not rotate. . In addition, if the opening 6 is widened as shown in Figure 1 so that the end surface of the heat collecting plate 2 does not come into contact with the heat collecting tube at the opening 6, groove-like scratches on the heat collecting tube due to thermal expansion and contraction can be prevented. I can do it. Furthermore, the fifth
The figure is a front view showing another embodiment of this invention, and the difference from the one in FIG. 1 is that a slit 7 is provided in the heat collecting plate 2. This allows a certain amount of thermal stress to be released, and the occurrence of warpage and waving can be further reduced. Note that the effect of this invention can be obtained even if other known methods such as a method of crushing a copper tube are used as the caulking method.

According to this invention, when connecting the heat collecting plate and the heat collecting tube, the central part of the heat collecting plate is strongly caulked and both ends are weakly caulked, so that when the heat shock expands and contracts due to heat, the central part becomes the neutral point, and the heat collecting plate and the heat collecting tube are connected at both ends. The heat collecting tubes slide against each other and no thermal stress is generated, so the heat collecting plate does not warp or wave. In addition, since the center portion, which is the neutral point of thermal expansion and contraction, is strongly caulked, the heat collection plate and the heat collection tube are tightly connected at this portion, which prevents the heat collection plate from rotating during heat shock or transportation. Furthermore, since the openings of the end faces of the heat collecting plate are widened so that the cut surfaces at both ends of the heat collecting plate do not come into contact with the heat collecting pipe, it is possible to prevent groove-like scratches from being formed on the heat collecting pipe due to thermal expansion and contraction.
