Description

[Detailed explanation of the invention] This design combines a hot water storage tank with a built-in heat dissipating part of a heat pipe, and multiple solar heat collectors that integrally form a heat absorbing part of a heat pipe and a certain heat receiving part from a heat collecting plate. This article relates to a solar heat collector.

In recent years, as a solar heat collector, for example,
As shown in Publication No. 134841, a heat pipe type system has come into use in which solar heat collected in a heat receiving section is transferred to a hot water tank using a heat pipe to heat the water stored in the hot water tank. Ta.

Since such a collector does not allow water to pass through the heat receiving section, it has the advantage that there is no fear of freezing and there is little risk that the heat that has been collected will be radiated from the heat receiving section.

By the way, since the amount of hot water used in each household differs depending on the family structure, it is necessary to prepare several types of solar collectors with different heat collection and hot water storage capacities, which increases the cost of manufacturing equipment at the factory. It was a contributing factor.

Furthermore, once installed, it is difficult to expand and change the capacity, and it is necessary to purchase separate collectors depending on the amount of hot water that is insufficient.

These independent collectors have a make-up water valve built into their hot water storage tank, but this make-up valve is not necessary and costs increase due to the work required to attach the make-up water valve to the hot water tank and the increased number of parts. There were drawbacks.

Furthermore, when the collector is installed on the roof, this type of heat pipe type collector usually has a heavy metal heat pipe and heat collecting plate, and a heavy hot water storage tank as well. Therefore, the total weight is large, and if a single device is used to supply a standard amount of hot water of 2,001 liters for a typical household, it would be extremely difficult to transport and install the device.

In view of the above points, the purpose of this proposal is to make it possible to easily and inexpensively obtain a solar heat collection device with arbitrary heat collection and hot water storage capacity, as well as to facilitate transportation and installation. The embodiment will be explained according to the drawings showing the embodiment.

In FIG. 1, 1 has a hot water storage tank 5 having a water supply pipe 2 and a hot water outlet pipe 3 on a side wall 4 for taking out heated water upwardly;
The collector is integrally formed with a heat receiving part 7 disposed below for heating a heat medium for heating the water 6 in the hot water storage tank, and the collector has a heat receiving part 7 disposed below. A make-up water valve 9 such as a ball tap is installed between the water storage section 8 and the water supply pipe 2.
There are two types of collectors: a main collector 10 which has the same planar shape as the collector, and an auxiliary collector 10' which has the same planar shape as the collector and is used in connection with the main collector 10.By combining these, a solar heat collecting device can be constructed. be shaped.

That is, the main collector 10 has a ball tap 9, a water storage section 6, and a heat dissipation section 11 of a heat pipe that heats the water in the water storage section housed in a watertight container 12, as shown in FIG. In addition, by receiving the heat received from the hot water tank 5 covered with a heat insulating material 13 and sunlight or radiant heat through the heat collecting plate 14 and giving it to the heat absorbing part 15 communicating with the heat radiating part 11, The heat receiving section 7 is configured to vaporize a certain liquid heat medium and supply it to the heat radiating section 11.

Reference numeral 16 designates a partition plate that partitions the heat absorption part 15 and heat radiation part 11 of the heat pipe to prevent water in the water storage part 6 from leaking into the heat reception part 7 , and 17 designates a transparent plate that covers the upper surface of the heat reception part 7 .

The auxiliary collector 10' is obtained by removing the make-up water valve 9 from the structure shown in Fig. 1 and reducing the upper space 18 for housing this make-up water valve, and by otherwise having the same structure as Fig. 1, the main feature is improved. An auxiliary collector 10' having the same planar shape as the collector 10 is obtained.

The solar heat collecting device of the present invention formed by the main collector 10 and the auxiliary collector 10' configured in this way includes, for example, a hot water storage tank 5 whose capacity is set to the minimum amount of hot water used in a general household. The heat receiving part 7 corresponding to
When manufacturing units in large quantities and requiring hot water supply exceeding this minimum amount, an appropriate number of auxiliary units 1
0' and connect the water supply pipes 2 and hot water outlet pipes 3 of each collector (FIG. 2), a solar heat collector capable of supplying hot water of any capacity can be obtained.

As mentioned above, the solar heat collector according to the present invention integrates a hot water storage tank with a built-in make-up water valve such as a ball tap and a heat radiating part of a heat pipe, a heat absorbing part of a heat pipe, and a heat receiving part from a heat collecting plate. a main collector consisting of a hot water storage tank which does not have a make-up water valve but has a built-in heat dissipating part of a heat pipe and is connected to the hot water tank via piping, a heat receiving part which consists of a heat absorbing part of a heat pipe and a heat collecting plate; It consists of an auxiliary collector that is integrally formed with the main collector and is installed in parallel with the main collector, and has the following effects.

■ By combining the main collector with an appropriate number of additional auxiliary collectors, you can easily obtain heat collection devices with different heat collection and hot water storage capacities, and you can prepare two types of collectors: the main collector and the auxiliary collector. Therefore, it is possible to obtain inexpensive collectors through mass production.

■ When adding an auxiliary collector to an existing main collector, the auxiliary collector does not have a make-up water valve, so the cost of installing the make-up water valve and parts can be reduced, and the cost required for the addition can be reduced.

■ When converting a heat collection device with a standard hot water supply capacity of 200 liters, this type of heat pipe type heat collection device inevitably increases in weight, making it difficult to install it on the roof. Since it is divided into a collector and an appropriate number of auxiliary collectors, it is easy to transport and install it on the roof.

■ Since the hot water storage tank of the auxiliary collector is not equipped with a make-up water valve, the height of the hot water storage tank can be lowered, and in this case, the height of the auxiliary collector can be lowered and the packaging volume can be reduced.
