【発明の詳細な説明】
本発明は、ヒートパイプを有する集熱器と貯湯
タンクよりなる太陽熱温水器に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar water heater comprising a heat collector having a heat pipe and a hot water storage tank.
従来のこの種の装置（特開昭56―957）は、第
３図に示すような構成で、すなわちヒートパイプ
８の凝縮部８ａはネジ形状に形成しており、貯湯
タンク９の壁にシールして固着されているネジ容

ンク９との間で行つていた。なお、図中の１２は
貯湯タンク９を覆う断熱材である。 A conventional device of this type (Japanese Patent Application Laid-Open No. 56-957) has a configuration as shown in FIG. The liquid 11 in the hot water tank 9 is sealed with the liquid 11 between the screw container 10 and the hot water tank 9. Note that 12 in the figure is a heat insulating material that covers the hot water storage tank 9.
ここにおいて、ヒートパイプ８の挿入はネジ容
器１０にネジ込むために、ヒートパイプ８のネジ
状に形成された凝縮部８ａとネジ容器１０との接
触は局部接触になり、熱コンダクタンスが小さく
なるので集熱性能に悪影響を及ぼすことになり、
さらにヒートパイプ８の蒸発部に設けられている
集熱板が大きかつたり、ヒートパイプ８が複数本
連結されている場合には、ヒートパイプ８を回し
ながらネジ容器１０にネジ込むことは不可能であ
るという重大な欠点を有していた。 Here, since the heat pipe 8 is inserted into the screw container 10, the condensation part 8a formed in the shape of a screw of the heat pipe 8 and the screw container 10 are in local contact, and the thermal conductance becomes small. This will have a negative impact on heat collection performance.
Furthermore, if the heat collecting plate provided in the evaporation part of the heat pipe 8 is large or if multiple heat pipes 8 are connected, it is impossible to screw the heat pipe 8 into the screw container 10 while turning it. It had a serious drawback.
本発明はこのような従来の欠点を除去するもの
で、ヒートパイプの凝縮部を貯湯タンクに固着シ
ールされた熱交換用容器内へ回さずに容易に挿入
できたり、前記ヒートパイプ凝縮部の腐蝕等の保
護用容器を容易に装着でき、しかもヒートパイプ
の凝縮部と前記容器との接触部の熱コンダクスを
大きくすることを目的とするものである。 The present invention eliminates these conventional drawbacks, and allows the condensing section of the heat pipe to be easily inserted into the heat exchange container that is firmly sealed to the hot water storage tank without turning it. The object of this invention is to allow a container for protection against corrosion to be easily attached, and to increase the thermal conductivity at the contact portion between the condensing portion of the heat pipe and the container.
上記目的を達成するために、本発明はヒートパ
イプの凝縮部の材質より熱膨張率が小さくかつ熱
伝導性が良好な金属の被覆容器にて前記ヒートパ
イプの凝縮部を被覆し、前記被覆容器と貯湯タン
クをシールしたものである。 In order to achieve the above object, the present invention covers the condensing part of the heat pipe with a metal covering container that has a smaller thermal expansion coefficient than the material of the condensing part of the heat pipe and has good thermal conductivity, and the covering container and a sealed hot water tank.
この構成によつて、集熱器に日射があたるとヒ

膨張率もヒートパイプ凝縮部の方が被覆容器より

覆容器とヒートパイプ凝縮部との間に適当なすき
間があり容易に挿入または装着可能であつたもの
でも集熱時には、凝縮部と被覆容器とがピツタリ
接触し熱コンダクタンスを大きくすることがで
き、ひいては集熱効率をも向上できる。 With this configuration, when solar radiation hits the heat collector, the temperature of the heat pipe becomes higher than the temperature of the covering container that is in contact with the liquid in the hot water storage tank, and the coefficient of thermal expansion is also lower than that of the heat pipe condensing part. Because the heat pipe is larger than the covering container, due to the difference in thermal expansion, even if there was initially a suitable gap between the covering container and the heat pipe condensing part and it could be easily inserted or installed, when collecting heat, The condensing part and the covering container are in close contact with each other to increase the thermal conductance and, in turn, improve the heat collection efficiency.

３を覆う断熱材である。 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Figure 1 shows a cross section of the main part of a solar water heater in which the condensing part of the heat pipe is inserted into the hot water storage tank. 1a is formed, the condensing part 1a has fins 2a, and the coefficient of thermal expansion is equal to that of the condensing part 1.
A covering container 2 made of a material smaller than a is arranged in a loose fit, one end of the covering container 2 is closed, and a sealing cylinder 2b is formed at the other end,
The heat pipe 1 inserted into the connecting cylinder 4 provided in the hot water storage tank 3 and the hot water storage tank 4 are connected by a sealing member 5 made of a flexible material that connects both the sealing cylinder 2b and the connecting cylinder 4. It is sealed to prevent the liquid 5 from leaking. 7 is a heat insulating material that covers the hot water storage tank 3.

向上させることができる。 Next, to explain the operation of the solar water heater with the above configuration, when solar radiation is irradiated onto the heat collecting plate (not shown) and the evaporation part (not shown) of the heat pipe 1 and the heat is absorbed, the absorbed heat is is the condensing section 1a
The temperature of the condensing section 1a increases. Thermal expansion also occurs as the temperature rises, and the condensing portion 1a, which has a larger coefficient of thermal expansion than the covering container 2, eventually fits snugly into the covering container 2, which was initially loosely fitted and easy to attach and detach. This increases the thermal conductance of the contact area and improves heat collection performance.

きる。 When the material of the condensing part 1a is aluminum and the material of the coating container 2 is copper, the respective coefficients of linear expansion β are aluminum (β=23.9×10 -6 1/℃) copper (β=16.5×10 -6 1 /°C) {value at 20°C}, and the heat absorbed by the heat collecting plate (not shown) is transferred from the covering container 2 that is in direct contact with the liquid 6 in the hot water storage tank 3 to the condensing section of the heat pipe 7. Coupled with the fact that the temperature in section 1a is higher, the condensation section 1
a and the covering container 2 can be brought into close contact with each other.

縮部１ａをまもることができる。 In this way, when the covering container 2 and the condensing part 1a come into close contact with each other, not only does the thermal conductance of the contact part become large and the heat collection performance improves, but also when the material of the condensing part of the heat pipe 1 is aluminum, Although it cannot be inserted into the hot water storage tank 3 due to corrosion, the condensing portion 1a can be protected from corrosion by installing the copper coated container 2 as a protective container as in the present invention.

くなるので集熱性能を向上できる。 As described above, according to the solar water heater of the present invention, the condensing part is covered with a covering container made of a material whose thermal expansion coefficient is smaller than that of the material of the condensing part of the heat pipe, and the covering container and the hot water storage tank are sealed. Therefore, it is easy to insert and attach the heat pipe and the covering container, and the thermal conductance of the contact portion is increased, so that the heat collection performance can be improved.
