Description
【0001】[0001]
本考案は、流下式太陽集熱器の集熱面構造、特に集熱面の表側表面に沿って集 熱媒体を流下させ熱交換を行なう集熱面構造に係る。 The present invention relates to a heat collecting surface structure of a downflow solar collector, and more particularly, to a heat collecting surface structure in which a heat collecting medium flows down along a front surface of the heat collecting surface for heat exchange.
【0002】[0002]
集熱面に規制線を設け、この規制線により集熱媒体の流下方向を拘束する技術 は、例えば本件出願と同一の出願人による特願昭62−134376号(特開昭 63−297966号)により公知となっている。こうした規制線構造を用いれ ば好ましい流下性能が得られ、高い集熱効率の得られる利点がある。しかしなが ら、集熱効率に改善効果の得られる反面、規制線により集熱媒体の流下運動が妨 げられ比較的流量の大きな低温集熱器にとって必ずしも満足のいく結果は得られ ていない。また、海水や地下水等のような塩分、無機成分を含有する集熱媒体を 流下させる場合、塩あるいはカルシウム等の含有物質が析出し、この析出物が堆 積して集熱媒体の流下を妨げることがある。さらに、集熱面の広い集熱器の場合 には、集熱媒体の供給ポンプが停止した後にも多量の集熱媒体が集熱表面に残留 し大きな荷重が常時集熱面に加わることになり好ましくない。 A technique of providing a regulation line on the heat collecting surface and restraining the downward direction of the heat collection medium by this regulation line is disclosed, for example, in Japanese Patent Application No. 62-134376 (Japanese Patent Application Laid-Open No. 63-297966) filed by the same applicant as the present application. It is known by. The use of such a regulation line structure has the advantages that favorable downflow performance is obtained and high heat collection efficiency is obtained. However, on the other hand, although the heat collection efficiency can be improved, the regulation line hinders the downward movement of the heat collecting medium, so that satisfactory results are not always obtained for a low temperature collector with a relatively large flow rate. Also, when a heat collecting medium containing salt or inorganic components such as seawater or groundwater is made to flow down, the contained substances such as salt or calcium are deposited, and these deposits are deposited to prevent the flow of the heat collecting medium. Sometimes. Furthermore, in the case of a collector with a wide heat collecting surface, a large amount of heat collecting medium remains on the heat collecting surface even after the heat collecting medium supply pump stops, and a large load is constantly applied to the heat collecting surface. Not preferable.
【0003】 本考案の目的は、集熱媒体の流下運動を妨げることのない規制線を持つ集熱面 構造を提供することにある。An object of the present invention is to provide a heat collecting surface structure having a regulation line that does not hinder the downward movement of the heat collecting medium.

本考案によれば、流下式太陽集熱器の集熱面を構成するシート材料の表側表面 に、予定される集熱媒体の流下方向に沿って多数の凹所溝を並列に形成し、この 凹所溝の少なくとも縁の部分を覆う状態に集熱媒体の吸収層を付着してなる流下 式太陽集熱器の集熱面構造が得られる。 According to the present invention, a large number of recessed grooves are formed in parallel on the front surface of the sheet material that constitutes the heat collecting surface of the downflow solar collector, along the downflow direction of the expected heat collecting medium. A heat collecting surface structure of a downflow solar collector in which an absorption layer of a heat collecting medium is attached so as to cover at least the edge portion of the recess groove is obtained.

【作用および考案の効果】 前述の如く構成することにより、集熱媒体は両側を吸収層により挟まれた状態 で凹所溝の平滑な底表面に沿って円滑に滑りながら流下していく。これにより、 流下する集熱媒体は吸収層により流下方向の拘束は受けるものの流下集熱媒体の 本体部分は円滑に流れていくことができる。従って、塩分や無機成分の析出がな く所望の流速を確保することができる。また、熱媒体比較的流量を多く設定する ことのある流下式低温集熱器にとって吸収層に吸着したまま残留する集熱媒体の 量も少なくなり、広域集熱面上に多量の集熱媒体が残留して大きな積載荷重の加 わることがない。[Advantages and Effects of the Invention] With the above-described configuration, the heat collecting medium is slid down along the smooth bottom surface of the recess groove while being sandwiched by the absorbing layers on both sides. As a result, the heat collecting medium flowing down is restrained in the downflow direction by the absorption layer, but the main body portion of the downflowing heat collecting medium can smoothly flow. Therefore, a desired flow rate can be secured without precipitation of salt or inorganic components. In addition, the amount of the heat collecting medium remaining adsorbed in the absorption layer is small for the downflow type low temperature collector which may set a relatively large flow rate of the heat medium, and a large amount of the heat collecting medium is accumulated on the wide area heat collecting surface. It does not remain and a large load is applied.
