Embodiment Construction

[0008] In the figure, the heat collecting tube of the solar heater includes a base body 1, spiral fins 2, heat-absorbing paint 3, and reinforcement ribs 4, and the base body 1, fins 2, and reinforcement ribs 3 are made into one body through a metal die-casting process. , all surfaces of the substrate 1 and the fins 2 are coated with heat-absorbing paint 3 respectively. There are a certain number of protruding spiral fins 2 on the cylindrical surface of the base 1. The inner circle of the base 1 is provided with a circle of inwardly protruding ribs 4. The fins 2 not only increase the surface area for absorbing sunlight, but also protrude. The raised fins 2 can effectively reduce the wind speed flowing through the surface and reduce the heat dissipation. At the same time, due to the grooves formed by the fins 2, the heat is repeatedly reflected in it, further reducing the heat loss. Therefore, the present invention has the advantages of better heat absorption effect and high...

Abstract

The invention discloses a heat collecting pipe of a solar air heater. A base body, fins and reinforcing ribs are integrated through a metal die-casting technology; heat absorption coatings are coated on the surfaces of the base body and the fins respectively; a certain quantity of raised spiral fins are arranged on a cylindrical surface of the base body; the fins not only enlarge the superficial area for absorbing the sunlight, but also effectively reduce the wind velocity flowing through the surface and reduce the radiation of the own heat; simultaneously, because of a slot formed by the fins, the heat in the slot is repeatedly reflected, and the loss of the heat is further decreased. The heat collecting pipe of the solar air heater has the advantages of excellent heat absorption effect and high heat absorption efficiency.

Description

technical field [0001] The invention relates to a technology of a solar heater, in particular to a heat collecting tube of a solar heater. Background technique [0002] The heat collecting tube is the key component of the solar heater, and its main function is to absorb the energy of the sun and transfer the absorbed heat to the corresponding space. At present, the heat collecting tubes of solar heaters are all straight-through cylindrical structures in structure. Due to the limited surface area of ​​the cylinder, the area that can effectively absorb sunlight is also directly determined by the surface area of ​​the cylinder. Under the condition of flow velocity, the flow velocity of the air on its surface is faster, so its own heat is easily taken away by the wind. so. The heat collecting tube of the existing solar air heater has the defects that the limiting lighting surface is relatively small and its own heat is easy to dissipate. Contents of the invention ...
