<p>A header unit for the solar collector is provided to improve the unbalance between the heat absorption and heat radiation since the heat exchanging surface area of the horizontal tubes is enlarged. A header unit for the solar collector comprises a plurality of mounting holes(61) formed in a horizontal tubes(60) in which both ends is shut tightly, a rim(62) which is formed in the mounting hole of the horizontal tubes, a horizontal tubes which is arranged inside the head pipe(50), a binding hole(51) of the head pipe inserting the rim of the horizontal tubes, the top of the branch(70) is inserted into the mounting hole of the horizontal tubes.</p> |
