。Conventional structure and its problems When a heat pipe heat exchange section made of copper pipes is used in a solar water heater, the heat exchange section of the heat pipe is usually placed in the water of a hot water storage tank as a bare copper tube. Multiple lines are inserted. In this type of system, the water stored at an elevated temperature has a high copper ion concentration due to the elution of copper, which is the material of the heat exchanger. Corrosion typically occurs over the entire surface of the 2" copper pipe.

えることも多い。この銅イオンの溶出は、使用水に含ま
れる塩素イオン、硫酸イオン、硝酸イオン、残留塩素な
どの増加及び水素イオン濃度(PH)の低下による影響
が大きい為である。This copper ion concentration often exceeds the tap water standard of 1 ppm. This elution of copper ions is largely influenced by an increase in chlorine ions, sulfate ions, nitrate ions, residual chlorine, etc. contained in the water used and a decrease in hydrogen ion concentration (PH).

云われている「青い水」問題である。If water containing copper ions is repeatedly brought into contact with bathtubs, washbasins, and towels, insoluble blue substances may adhere to them. This is a fatty acid found in soap, sweat, etc.
This is because fatty acid steel or ammonium salt of copper is produced by reacting with ammonium, resulting in a blue substance. This is what is commonly referred to as the "blue water" problem.

There is a heat exchange section 4 above the heat pipe 2, which functions to transfer the amount of heat collected from the sun to the water 3b of the hot water storage tank 3.
この熱交換部4の上面に防食ユニット5を取りつける。A corrosion protection unit 5 is attached to the upper surface of this heat exchange section 4.

れる。This anti-corrosion unit 6 is machined to a size that allows it to be attached and removed at will from the upper opening 3a of the hot water storage tank, ie, from the portion where the water supply ball tap 6 is attached, as shown in FIG.
第3図に於て、この防食ユニット6の構造を説明する。The structure of this anti-corrosion unit 6 will be explained with reference to FIG.
6aがマグネシュームの棒で、これが熱交換部4よりも
イオン化傾向の犬なる金属として用いたものである。こ
の棒5aは図示の如く2本でもよいが、一本丈、もしく
は複数本であってもよい。6a is a rod of magnesium, which is used as a metal that has a higher tendency to ionize than the heat exchanger 4. The number of the rods 5a may be two as shown in the figure, but it may also be one length or a plurality of rods.

両切断、先端部はL字状に曲げておく(第6図)。The magnesium rod 6a used is one in which the core wire is not simultaneously processed, that is, the entire round rod is made of magnesium material. The fixed wire 51 is made of stainless steel wire or the like and processed into a 97-shape and has spring elasticity. Cut both sides in a V-shape and bend the tip into an L-shape (Figure 6).

、隙間腐食を起す様な条件を作らない。Structurally, it is this length, but when installing it, hook this fixed wire 51 to the central pipe of the three heat exchange parts 4, and then connect the two magnesium rods 5a in a cross shape as shown in the figure. The two ends of the fixing wire 61 are hooked onto the heat exchange parts 4 on both sides and fixed. In this state, the fixed line 51 crosses the heat exchange section 4. This heat pipe 2 is usually formed of a plurality of pieces, but the length of three pieces is used for attaching the present anticorrosion unit 6. Further, the plurality of heat pipes 2 are electrically integrated by the fins 2a of the heat collecting portion. When the magnesium rod 5a is worn out after the anticorrosion unit 6 has been used for a long period of time, it becomes disconnected as shown in FIG. Even if detachment is incomplete, the fixing wire 61 to the heat exchange part 4 has a space at the L-shaped bent part (b), and does not create conditions that would cause crevice corrosion.

が極めて少ない。On the other hand, as a structural feature, the mutual contact state of the fixed wire rsl, the magnesium rod 5a, and the heat exchange part 4 is as follows.
As shown in (a) of the figure, the round wire and round bar are in a perpendicular state, and all points are basically in contact with each other, and there are extremely few areas that cause normal crevice corrosion.

で防食機能が安定する。Effects of the Invention In the present invention, metals that are more ionized than copper are actively eluted, and the leaching of copper is suppressed, so that the "blue water" problem does not occur. In addition, since spring elasticity is used, electrical connection with the heat exchange part is maintained well over a long period of time underwater, resulting in stable corrosion protection.

る。That is, although it is effective as a sacrificial anode rod, when the sacrificial anode rod wears out, it becomes necessary to add it again. If left without this addition, the relationship between the fixed wire and the heat exchanger will usually create an opportunity for electrolytic corrosion or crevice corrosion due to contact between different metals. According to this configuration, the sacrificial anode rod is consumed, that is, the fixed wire is detached, so there is no need for the above-mentioned concerns. Even if insufficient separation occurs for some reason, there is almost no risk of crevice corrosion since all structural contact parts are points. On the other hand, for the above-mentioned purpose, the structure of the fixed wire requires only L-shaped bending, which is easy to work with, can be provided at low cost, and has high reliability.
