Description

[Detailed explanation of the idea] Industrial applications This invention relates to a solar heat collector.

BACKGROUND TECHNOLOGY In general, a solar heat collector includes a pair of front and rear headers each having a water supply or drainage pipe connection at one end.
It is equipped with parallel water pipes that communicate with both headers, and a heat collecting plate is attached to each water pipe. Conventionally, it has already been known to support the header of a solar heat collector using a header support (for example, see Utility Model Application Publication No. 116061/1983). It is already known that in order to prevent damage to the front header, the end of the front header on the roof of a building, etc. on the pipe connection side is sloped at a different level from the other end. (See, for example, Japanese Utility Model Application Publication No. 116956/1983).

Problems to be Solved by the Invention However, conventionally, when a header is supported by a header support, the upper end of the header support is fixed to the frame of the solar heat collector with screws, and
A separate insulation material is placed under the header support.
This poses a problem in that workability is extremely poor and manufacturing of the solar heat collector is troublesome. Conventionally, in order to drain water by lowering the end of the front header on the pipe connection side, the header and the parallel water pipes were connected not at right angles but at a predetermined angle. On the roof of a building, etc., the end of the header on the pipe connection side is sloped at a different level and lower than the other end. The heat collector is not rectangular when viewed from the plane, but has an irregular shape.
There was a problem that the heat collector was not easy to manufacture.

The purpose of this invention is to solve the above-mentioned problems of the prior art, and to remove the header by simply placing a heat insulating molded body made of synthetic resin on the upper surface of the bottom plate at least at the front end of both the front and rear ends of the solar heat collector. It can be supported reliably, has excellent heat retention properties, and therefore has excellent workability. It is very easy to manufacture solar heat collectors, and it also prevents residual water from freezing when draining water in winter. In order to prevent damage to the header, the header can be tilted at the same level on the roof so that the end of the header on the pipe connection side is lower. Water pipes can be connected orthogonally,
The object of the present invention is to provide a solar heat collector that is easy to manufacture because the heat collector composed of both headers and water pipes can be made into a rectangular shape when viewed from above.

Means for Solving the Problems In order to achieve the above object, this invention consists of a pair of front and rear headers each having a water supply or drainage pipe connection at one end, and a parallel water pipe connected to both headers in communication with each other. A heat insulating molded body made of synthetic resin that supports the header is disposed on the top surface of the bottom plate at least at the front end of both the front and rear ends of the solar heat collector having In addition to having a recess for fitting the header, the inner wall thereof is provided with notches for fitting the end of the water pipe, which are arranged in the same number and at the same pitch as the water pipes, and the bottom surface of the recess for fitting the header is located at one end from the other end. The side wall of the end of the heat insulating molded body on the lowest side of the bottom of the recess is provided with a recess for fitting the pipe connection part connected to the recess, and the header of the heat insulating molded body is Fitting recess and pipe connection part The header and pipe connection part are fitted into the fitting recess, and the end of the water pipe is fitted into each notch, and when installed on the roof of a building, etc. The gist is a solar heat collector in which the header is inclined so that the end of the header on the pipe connection side is lower at the same level on the roof.
