Abstract

PURPOSE:To prevent connecting holes for connecting a heat collecting plate and headers from being blocked with weld beads by a method wherein in the titled solar heat collector comprising the heat collecting plate having the headers connected to both sides thereof, each of the headers is formed of a hollow tubular member fusion- bonded with a guide and drilled with the connecting hole and the heat collecting plate is fusion-bonded to the guide. CONSTITUTION:The solar heat collector made of a thermosetting resin material is formed of the heat collecting plate 2 having a number of flat water passages arranged therethrough and the hollow tubular headers 1 connected to both sides of the heat collecting plate 2, respectively. To fabricate such solar heat collector, the guide 6 of a sectional configuration identical with that of the heat collecting plate 2 is fusion- bonded to a hollow tubular member 1'; after removing the weld beads 5 formed inside the fusion-bonded section, the connecting hole 4 is drilled in the member 1' from on the side of the guide 6 to thereby provide each of the headers; and the heat collecting plate 2 and the free end surface of the guide 6 are butt-welded to each other to thereby complets the fabication. Thus, according to the above method of fabrication, the connecting hole 4 is drilled after the hollow tubular member 1' and the guide 6 are bonded together so that the connecting hole 6 is not blocked with the weld beads 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for assembling a solar heat collector, and particularly to improvements in a solar heat collector made of thermoplastic resin.

As one of the ways to form a solar heat collector using thermal cTtIi steel resin, hollow tubular headers 2 are installed at both ends of a heat collecting plate in which a large number of passageways are arranged in the form of a flat plate at 15 as shown in Figure 1. When manufacturing a heat collector IIs such as 0 or 5 C by connecting a Connecting holes 4 are drilled corresponding to the positions of the water passages, and then the end face of the heat collecting plate 1 and the header 2 are pressed together [φ steps are taken to heat and press the layer and melt the layer].
However, in this method, the areas of the hollow tubular body, the heat collecting plate, and the O protrusion are different from a, and the area of the hollow tubular body is generally larger. So even heating and perfect fl! 1N1: Medium to get it! The heat of the tubular body is greater than that of the heat collecting plate, and when it is welded, it is called a bead 5. The foramen was small (about 4 or so), and there was a place where it could be completely closed (Fig. 6).

The present invention was made in view of the above circumstances, and includes:
In the second method of assembling a solar heat collector consisting of a heat collecting plate and a header arranged in the form of a large number of permeable channels KSF plates, a guide having the same cross-sectional shape as the heat collecting plate in the longitudinal direction of the hollow tubular body is used. The method is characterized in that a through hole is formed in advance to reach the inner surface of the hollow tubular body, D is a header, and the heat collecting plate is inserted into the header to form a melt layer.

The present invention will be explained below based on the drawings showing the embodiments.
Figure A shows a state in which a guide 6 having the same plane shape as the heat collecting plate is laminated on the middle 9-tubular body 1'. The guide 6 is made by cutting the end part II of the heat collecting plate to a length that can be drilled and molding it separately from the next suitable one.
Holes 11 to 9 are all drilled toward the inner surface of the tubular body 1', internal beads are removed, and stray holes 4 are provided to form a header. Next, the heat collecting plate 2 and the end 111 of the guide 6 of the header are connected to the heat collecting plate 2 and the end 111 of the header guide 6 shown in the fourth part B. Fewer heat collectors can be used.

For example, a water passage w with an inner diameter of 6 tmφ: The size of the bead made by welding a guide header with connecting holes of the same diameter as the heat collecting plate is 1 to 2 mIII, and has a good water flow capacity. It is clear from the above explanation that the present invention is
By drilling #N bale connecting holes in the tubular body and guide, it is now possible to manufacture solar heat collectors that will not be blocked by connecting holes or beads.
