Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heat collector, and in particular to improvements in piping equipment in a solar heat collector.

In traditional solar heat collectors, the piping materials are
The heating tank is connected to the solar heat collector using two pipes, one for the return and one for the feed, using resin or metal pipes.
Since there are two pipes, it takes a lot of man-hours to fix the pipes and insulate them, and especially in the case of resin pipes, it is difficult to run the two pipes neatly and parallelly, and it is aesthetically unsatisfactory. The problem was that it was undesirable.

The purpose of the present invention is to solve such problems by using double pipes made of synthetic resin for the two pipes for sending to and returning from the solar heat collector, and to connect the solar heat collector and the heat storage tank with each other. The purpose of the present invention is to provide a solar heat collector that connects to the solar heat collector through a dedicated connection adapter.

Next, the solar heat collecting device according to the present invention will be described based on examples. FIG. 1 is an external view showing one embodiment of the present invention, in which 1 is a solar heat collector, 2 is an expansion tank, and 3 is a solar heat collector 1.
4 is a lower connection pipe of the solar heat collector 1, 5 is a connection adapter, 6 is a double pipe, 7 is a heat collection pump, 8 is a heat storage tank, and 9 is a heat exchanger.
In such a configuration, the upper connecting pipe 3 and lower connecting pipe 4 of the heat collector 1 are connected to the connecting adapter 5 through the shortest distance. In the heat storage tank 8 as well, the inlet-side pipe and the outlet-side pipe of the heat exchanger 9 are connected to the connection adapter 5. These connection adapters 5 are composed of a double metal cylinder as shown in FIG.
A connection port 11 is provided on the side of the pipe 0, and a part of the inner cylinder 12, which is the high-temperature side pipe, is provided with a retractable part 13 formed of a bellows or the like. It protrudes from the lower end of the outer cylinder, and the connection port 14 is connected to the upper end.

When connecting the solar heat collector 1 and the heat exchanger 9 using such a connection adapter 5, connect the high temperature side pipe to the connection port 14 of the inner cylinder 12 of each connection adapter 5, 5. Also, the outer cylinder 10
The pipes on the low temperature side are connected separately to the connection ports 11 of. A double pipe 6 is connected between both connection adapters 5, 5. The connection between the double pipe 6 and the connection adapter 5 is as shown in FIG.
5 into the inner cylinder 12 of the connection adapter 5 and fixed it with the band 16, then insert the outer pipe 17 into the outer cylinder 10 while pushing the inner cylinder 12, and then tighten the band 1.
It should be fixed at 8.

By driving the heat collecting pump 7 in this connected state, the heat collected by the solar heat collector 1 is transferred to the heat stored in the heat storage tank 8 via the heat medium flowing in the double pipe 6. It is sent to the exchanger 9 and stored as heat.

As explained above, in the present invention, it is possible to connect the solar heat collector and the heat storage tank with a double pipe by using a connection adapter, so it is possible to install the solar heat collector and the heat storage tank with a double pipe, so it is possible to install the solar heat collector and the heat storage tank with the same amount of time and effort as installing a single pipe. Not only is it possible to install a solar heat collector after the piping is completed, the piping work cost is low, and there is less damage to the aesthetics, but there is also a retractable part in the middle of the inner cylinder of the connection adapter. , and the tip of the inner tube protrudes from the tip of the outer tube when not connected, so after connecting the inner tube of the connection adapter and the inner pipe of the double pipe, connect the connection part to the inside of the outer tube. Since the outer cylinder and the outer pipe can then be connected, the outer cylinder does not get in the way when connecting the inner cylinder, and the connection between the outer cylinder and the outer pipe can be made easily between the connected inner cylinder and inner pipe. Since this can be done without considering the length, it has the excellent effect of making it possible to connect double pipes extremely efficiently and reliably.
