Detailed Description

As shown in fig. 1 to 4, the direct air-cooling condenser with the solar cell panel of the present invention, like the existing direct air-cooling condenser, also includes a bottom frame 10 and a horizontal steam distribution pipe 13 fixedly connected to the bottom frame 10, wherein a tube bundle row 12 is communicated with the lower side of the steam distribution pipe 13, and a fan 9 is disposed on the bottom frame 10 below the tube bundle row 12.

Still including being located the solar panel 2 of steam distribution pipe 13 top, solar panel 2 rotates through rotating device and chassis 10 to be connected, is provided with in the edge of chassis 10 and encloses the bounding wall 1 that keeps off including steam distribution pipe 13 and tube bank row 12, has closed state and open mode between solar panel 2 and the bounding wall 1. The closed state means that the edges of the solar panel 2 and the enclosing plate 1 are overlapped to form a closed structure, and the open state means that the edges are not overlapped to form an open structure.

In addition, since it is difficult for one solar panel 2 to cover the entire air cooling island due to the generally large size of the air cooling island, the number of solar panels 2 may be two or more as appropriate, and the edges of adjacent solar panels 2 abut against each other in the closed state.

In summer, the device can adjust all the solar panels 2 to the opening state and enable the solar panels 2 to face the sun irradiation direction generally as shown in fig. 3, and due to the shielding and light absorption effects of the solar panels 2, the steam distribution pipes 13 and the pipe bundle rows 12 in the air cooling island are in shade, so that the normal heat dissipation capability of the equipment is prevented from being influenced by the temperature rise of the equipment after the equipment is directly exposed to the sun. The power generated by the solar panel 2 can be used for illumination and the like.

In winter, when the solar panel is cold, as shown in fig. 4, most of the solar panels 2 can be in a closed state, and a small part of the solar panels 2 are opened, so that the enclosing plate 1 and the solar panels 2 form a semi-closed structure together, the convection of air in the semi-closed structure is relatively reduced, the heat preservation effect is achieved to a certain extent, and the heat dissipation fins are prevented from being frozen due to too low temperature. In addition, in order to further enhance the freezing prevention capability of the device, in this embodiment, the heating wires 11 (commonly called electric tracing) are further disposed on the tube bundle rows 12, and the heating wires 11 are electrically connected to the solar panel 2, so that the generated energy of solar energy can be utilized locally to heat the tube bundle rows 12.

In addition, this embodiment the rotating device includes support 5 and the even board 3 of being connected with support 5 rotation, even board 3 and the central department fixed connection of solar panel 2 bottom surface, and support 5 is connected with chassis 10. The connecting structure can enable the gravity center of the solar panel 2 to be positioned above the support 5, and can prevent the gradual change of the opening angle of the solar panel 2 caused by the gravity center of the solar panel being far away from the support point when the solar panel 2 is in the opening inclined posture.

In more detail, the rotating device of the present embodiment further includes a rotating shaft 6, a bottom end of the rotating shaft 6 is rotatably connected to the bottom frame 10, a top end of the rotating shaft 6 is fixedly connected to the support 5, and an axial direction of the rotating shaft 6 is perpendicular to a rotational axial direction of the connecting plate 3 and the support 5. The rotating shaft 6 is arranged, so that the solar panel 2 can not only tilt and swing vertically, but also rotate horizontally in a full circle, thereby adapting to the continuous change of the position of the sun in one day and achieving the best sun shading and electric energy conversion effects. In addition, as the solar panels 2 in the long rows are uniformly inclined at a fixed angle, if wind comes from the back side of the inclined plane, a large amount of wind can be poured into the air cooling island, so that the original airflow path of the blast of the fan 9 is disturbed, and the heat dissipation effect is influenced; and adjacent solar panel 2 just can form the space after self level is to the rotation, so then the inclined plane dorsal part comes wind just can flow away through this space to reduce the radiating influence in air cooling island.

More specifically, the top end of the rotating shaft 6 of the present embodiment is fixedly connected to the center of the bottom surface of the support 5, and the axis of the rotating shaft 6 is coaxial with the axis of the fan 9. Can make every fan 9 top all set up a solar panel 2 like this, because solar panel 2 blocks the effect and can produce the influence to the blast air flow path of fan 9, after solar panel 2 and the cooperation of fan 9 one-to-one, relatively independent operation unit has been formed, thereby can effectively improve the prediction and control to blast air flow path, especially when solar panel 2 all deflects with the slope of same angle, solar panel 2 and the fan 9 of one-to-one can prevent to produce the sinuous flow between each unit, avoid reducing the radiating efficiency.

More specifically, the rotating device of the embodiment further comprises a horizontal motor 4 and a vertical motor 7, wherein the shell of the horizontal motor 4 is fixedly connected with the support 5, and the output shaft of the horizontal motor 4 is fixedly connected with the connecting plate 3; the shell of the vertical motor 7 is fixedly connected with the underframe 10, and the output shaft of the vertical motor 7 is fixedly connected with the rotating shaft 6. The motor is used for driving the solar panel 2, so that the manual adjustment is avoided, and the trouble and the labor are wasted.

However, since the temperature in the air cooling island is relatively high, and especially the temperature of the steam distribution pipe 13 is the highest, the service life of the motor is seriously reduced due to the high temperature when the vertical motor 7 is very close to or even arranged on the steam distribution pipe 13, so the present embodiment is further provided with a steel frame 8, and the housing of the vertical motor 7 is fixedly connected with the steel frame 8. In order to firmly fix the vertical motor 7, the steel frame 8 is fixedly connected with the underframe 10 and the coaming 1. Furthermore, the steel frame 8 is spaced from the steam distribution pipe 13 to reduce the effect of the high temperature air near the steam distribution pipe 13 on the life of the vertical motor 7.
