Specific embodiment

The solar energy fin heat exchange pipe of double pipe structure as shown in Figure 1, including vacuum heat absorbing pipe 1, medium pipeline, heat transmission fin 3, medium pipeline includes the first pipeline 21 and second pipe 22, and first pipeline 21 is " u "-shaped structure with second pipe 22, First pipeline 21, second pipe 22 are inserted into vacuum heat absorbing pipe 1 respectively, vacuum heat absorbing pipe 1, the first pipeline 21, second The axis of pipeline 22 is parallel to each other, and the heat transmission fin 3 is fixedly connected on the first pipeline 21 and second pipe 22, and described first The two ends of pipeline 21, the two ends of second pipe 22 are connected with medium inlet 23 and media outlet pipe 24 respectively.

Due to the limitation of prior art, when vacuum heat absorbing pipe is made, can only often make the pars intermedia of vacuum heat absorbing pipe Point vacuum state is reached, this results in medium pipeline center section and two end portions and is heated inequality, the flowing in medium pipeline The flexural deformation of medium pipeline can be caused under the Action of Gravity Field of water, because single ventilating water pipe caliber is larger so that medium tube Water-flowing amount in road is larger, and the gravity suffered by medium pipeline also increases, and exacerbates the temperature distortion of medium pipeline.

The solar energy fin heat exchange pipe of double pipe structure employs double pipe structure, reduces in the case where unit water-carrying capacity is constant The caliber of medium pipeline, makes the gravity of the water suffered by medium pipeline diminish, and reduces the influence of medium pipeline temperature distortion.
