Description

[Detailed Description of the Invention] The present invention includes a heat collector outer frame in which a heat collecting plate having a fluid passage is installed, and a connecting pipe that communicates with the fluid passage of the heat collecting plate and serves as an inlet and an inlet for the fluid. , relates to a solar heat collector in which the connecting pipe protrudes below the bottom plate of the collector, and aims to provide a structure that allows reliable and easy piping connection when installing the collector. .

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

Figure 1 shows the external appearance of the heat collector of the present invention. 1 is an outer frame of the heat collector with a heat collecting plate 2 inside, and the heat collector is floated on the bottom of the outer frame 1 of the heat collector. A metal holder 3 is provided.

FIG. 2 is a side view of the heat collector, in which a connecting pipe 4 is provided inside the holder 3 and serves as an inlet and outlet for fluids such as water and heat medium.

FIG. 3 is a view of the heat collector viewed from the bottom side, and the heat collector bottom plate 5 is provided with a recess 6 around the connecting pipe 4.

FIG. 4 shows a cross-sectional view of the heat collector, and the heat collector plate 2
has a fluid passage 7, and a connecting pipe 4 communicating with the fluid passage 7 projects downward from the heat collector bottom plate 5.

Further, an L-shaped rising portion 8 is provided at the bottom of the heat collector outer frame 1 and projects upward, that is, toward the heat collecting plate 2 side, and the heat collector bottom plate 5 is attached to this rising portion 8 with screws 9.

The concave portion 6 provided in the heat collector bottom plate 5 is made to protrude toward the heat collector plate 2 side, and the presence of this concave portion 6 increases the amount of protrusion of the connecting pipe 4.

In this case, a threaded part 11 having a certain thread length is provided on the protruding part of the connecting pipe 4 in order to attach a piping material 10 such as an elbow as shown in FIG.
1 is a rising portion 8 provided at the bottom of the heat collector outer frame 1.
By attaching the heat collector bottom plate 5 to the heat collector bottom plate 5 and providing the concave portion 6 in the heat collector bottom plate 5, it is possible to completely expose the heat collector bottom plate 5, so that the piping material 10 such as an elbow can be reliably attached to the threaded portion 11. .

However, since the lower end surface of the connecting pipe 4 is provided with a threaded portion 11 having a certain thread length, the heat collector outer frame 1
Because it protrudes slightly downward from the bottom of the connecting pipe 4, if the collector is placed on a roof support or ground support in this state, only the lower end of the connecting pipe 4 will be in contact with the support. When a piping material 10 such as an elbow is attached to the threaded portion 11 of the connecting pipe 4, the installation of the four heat collectors becomes extremely unstable.

Therefore, the present invention further fixes the holder 3 to the bottom of the heat collector outer frame 1 with screws 12, thereby making the heat collector float by the height of the holder 3, and connecting the end face of the protruding part of the connecting pipe 4 with the holder. A space 13 is provided between the bottom part of the tool 3 and the bottom part of the tool 3.

As a result, this space 13 can be used to provide piping material 1 such as an elbow.
0 to the threaded portion 11 of the connecting pipe 4, the attachment can be done reliably and easily.

In addition, in FIG. 4, 14 is a heat insulating material, and 15 is a glass or transparent resin plate attached to the upper part of the heat collector outer frame 1 with a presser plate 16.

Figures 6 and 7 show the location where the heat collector ρ is installed. Figure 6 shows the heat collector installed on a support stand 18 provided on the roof 17, and Figure 7 shows the heat collector ρ installed. The device is shown installed on a support stand 20 provided on the ground 19.

As described above, according to the present invention, a rising portion protruding toward the heat collecting plate is provided at the bottom of the outer frame of the heat collector, a bottom plate of the heat collector is attached to the rising portion, and a connecting pipe is attached to the bottom plate of the heat collector. Since there is a recess around the heat collector plate that protrudes toward the heat collector plate, it is extremely easy and reliable to connect piping materials such as elbows to the connecting pipes. is equipped with a holder that floats the heat collector, and a space is provided between the end surface of the protruding part of the connecting pipe and the bottom of the holder, so that when the heat collector is fixed to a support such as a roof, the elbow The piping materials such as
Since no abnormal force is applied to the connecting pipe, various practical effects can be achieved, such as being able to prevent abnormal situations such as deformation of the heat collector and water leakage.
