【考案の詳細な説明】
本考案は蓄熱タンクに関し、更に詳細には、例
えば太陽熱を利用して温水を得るソーラシステム
において熱交換器を使用する間接加熱方式の蓄熱
タンクに関する。[Detailed Description of the Invention] The present invention relates to a heat storage tank, and more particularly, to an indirect heating type heat storage tank that uses a heat exchanger in a solar system that uses solar heat to obtain hot water.
従来、この種の蓄熱タンクは第１図に示される
ように構成されていた。すなわち、従来の蓄熱タ
ンク１は内部に熱交換器２を配置し、この熱交換
器２からパイプ３ａ，３ｂは蓄熱タンク１の側壁

され、これにより熱交換器２が蓄熱タンク中に支
持されている。 Conventionally, this type of heat storage tank has been constructed as shown in FIG. That is, the conventional heat storage tank 1 has a heat exchanger 2 disposed therein, and pipes 3a and 3b exit from the heat exchanger 2 to the outside of the heat storage tank through an opening 4 formed in the side wall of the heat storage tank 1. There is. The pipes 3a, 3b are fixed to a support plate 5 used as a closing plate for closing the opening 4, thereby supporting the heat exchanger 2 in the heat storage tank.
ところで、このような蓄熱タンク１は鉄系の材
料で形成されており、水に触れると腐蝕してしま
うため、蓄熱タンクの形成材料より貴な材料の電
極６をパツキン７により電気絶縁してその壁部に
取付け、電極６と蓄熱タンク１との間に直流電流
を流して防蝕する外電防蝕法により防蝕されてい

料であり、これらも電気絶縁しないとどちらか卑
な材料の方が腐蝕してしまうことになるし、同時
に前述の外電防蝕が効をなさないことになつてし
まう。そのため、熱交換器２を支持していいる支
持板５は蓄熱タンク１に電気的に絶縁されて開口
部４を封密的に閉鎖すべく取付けられている。 By the way, such a heat storage tank 1 is made of an iron-based material and will corrode if it comes into contact with water. It is attached to a wall and is protected against corrosion by an external electric corrosion protection method in which a direct current is passed between the electrode 6 and the heat storage tank 1 to prevent corrosion. In addition, the heat exchanger 2 and the heat storage tank 1 are made of different materials, and if they are not electrically insulated, whichever material is more base will corrode, and at the same time, the external electrical corrosion protection described above will not be effective. It becomes a thing. Therefore, the support plate 5 supporting the heat exchanger 2 is attached to the heat storage tank 1 so as to be electrically insulated and sealingly close the opening 4.
すなわち、蓄熱タンク１の開口部４の周縁には
壁部を外方へ180度折り返えしてなるフランジ８
が形成されている。このフランジ８の周縁は更に
90度屈曲されて蓄熱タンクの側方外向きに形成さ

の間隙は、第１図からも明らかなように非常に狭
くなつている。 That is, at the periphery of the opening 4 of the heat storage tank 1, there is a flange 8 formed by folding the wall portion outward by 180 degrees.
is formed. The periphery of this flange 8 is further
It is bent 90 degrees and faces outward from the side of the heat storage tank. In this way, the flange 8 is made thin and has a drawn shape in order to reduce the material cost as much as possible, and the inner diameter of the flange peripheral edge 9 is set to a minimum diameter that is only slightly larger than the outer diameter of the support plate 5. There is. This support plate 5 is electrically insulated from the heat storage tank 1 and has a rubber gasket 10 for sealing.
The support plate 5 is closely attached to the flange 8 through a plurality of tightening bolts 11 arranged at intervals around the support plate 5 . Therefore, the gap between the flange peripheral edge 9 and the support plate 5 peripheral edge is extremely narrow, as is clear from FIG. 1.
このような構造を有する蓄熱タンク１が、例え

めてしまい、両者を電気的に導通させてしまうこ
とになる。 If the heat storage tank 1 having such a structure is placed in a high temperature and high humidity condition, for example during the rainy season, and furthermore, low temperature water such as well water flows into the heat storage tank 1 and is left for several hours, it will not be supported. Condensation occurs on the surfaces of the plate 5, flange 8, etc. The degree of dew condensation is determined by the water temperature inside the heat storage tank 1, the ambient temperature outside the tank, the humidity, and the degree of insulation. Therefore, if the degree of condensation is large, the gap between the peripheral edge of the support plate 5 and the peripheral edge of the flange 9 has a shape that allows water to accumulate easily, so the condensed water droplets fill the gap and cause electrical conduction between the two. This will result in
これらの不都合を解消すべく、フランジ周縁の
内径を支持板の外径に対しかなり大きくし両者の
間隙を大きくとるとか、熱交換器取付け部分を完
全に被つて断熱するなどの方法が考えられるが、
これによるとフランジの材料コストが高くなると

るなどの欠点があつた。 In order to eliminate these inconveniences, methods such as making the inner diameter of the flange periphery considerably larger than the outer diameter of the support plate and creating a large gap between the two, or completely covering the heat exchanger mounting area and insulating it are possible. ,
This method has disadvantages such as an increase in the material cost of the flange or the need for expensive heat insulating material, which increases the cost.
従つて、本考案は、開口部から挿入配置された
熱交換器を支持すると共に前記開口部を密閉すべ
く支持板を取付ける際結露などによつて支持板に
対する電気的絶縁を損うことのない安価な手段を
構じた蓄熱タンクを提供することにある。 Therefore, the present invention supports a heat exchanger inserted through an opening, and when installing a support plate to seal the opening, the electrical insulation with respect to the support plate is not damaged due to condensation or the like. An object of the present invention is to provide a heat storage tank equipped with inexpensive means.
以下、本考案の蓄熱タンクを第２図に示された
一実施例を参照して更に詳細に説明する。この実

一の参照符号を付してその説明を省略する。 Hereinafter, the heat storage tank of the present invention will be explained in more detail with reference to an embodiment shown in FIG. In FIG. 2 showing this embodiment, parts that are the same as or corresponding to the conventional heat storage tank shown in FIG.
第２図で示された一実施例の蓄熱タンク２０

と同様である。 An embodiment of a heat storage tank 20 shown in FIG.
1 is provided with a flange 8 formed by folding back the wall portion at the inner circumferential edge of the opening 4 by 180 degrees, similar to the conventional one. However, in this embodiment, the peripheral edge 21 of the flange 8 is further bent by 90 degrees to face inward on the side of the heat storage tank. That is, the peripheral portion 21 is attached to the support plate 5 attached to the flange 8.
It is formed facing the opposite side. The other parts are the same as the conventional heat storage tank shown in FIG.

品を使用することはないので安価にできる。 In this way, in the heat storage tank 20 of the embodiment, the flange peripheral edge 21 and the peripheral edge of the support plate 5 are separated from each other by a large distance in the lateral direction, and moreover, both form a gap that can be filled by dew condensation or the like. Therefore, electrical conduction caused by such water droplets can be prevented, and since no special additional parts are required for this purpose, the cost can be reduced.

の絶縁の完全性が達成できる。 As explained above, according to the heat storage tank of the present invention, even if dew condenses on the flange or support plate of the heat storage tank, water droplets that would cause electrical continuity between the flange and the support plate do not form; That insulation integrity is achieved by inexpensive means without the use of expensive insulation materials or significant material additions to the flange.
