Solar panel structure with plasticity

Abstract

A solar panel has a plurality of heat collecting manifold, a water inlet tube and a water outlet tube that are formed as one body by plastic molding, so that the heat collecting manifold can be vertically arranged between the water inlet tube and water outlet tube, and connected therewith. The solar panel is also formed as one body by plastic molding, so a rib piece can be used to connect between the collecting manifold. In one embodiment, when the collecting manifold of the solar panel is formed, every sectional surface of the collecting manifold can be formed as hexagonal or octagonal, so every sectional surface thereof can be used as a force-receiving portion. Also, one side of the rib piece has a recessed portion to enable the other side thereof to relatively protrude to form a resilient portion, and the recessed portion and resilient portion are all V-shaped.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a solar panel structure with plasticity that can be installed in a solar water heater, and more particularly to a solar panel structure with plasticity having heat-collecting manifold with resilience.BACKGROUND OF THE INVENTION[0002]A conventional solar panel is shown in FIG. 7. The conventional solar panel 30 has a heat collecting manifold 31, a water inlet tube 32 and a water outlet tube 33 that are formed as one body by plastic molding, so the heat-collecting manifold 31 can be vertically arranged between the water inlet tube 32 and water outlet tube 33, and connected therewith. Also, a rib piece 34 is connected between the heat collecting manifold 31.[0003]When in use, the solar panel 30 is installed at a solar water heater. The cold water to be heated is provided from the water inlet tube 32 to the heat collecting manifold 31, and when the water moves upwards, it absorbs the heat of the sun to heat up the cold water, ...

AI Technical Summary

Benefits of technology

The present invention is a solar panel for collecting heat that has an improved design. It includes a connecting head with tooth-like structures to prevent external hoses from falling off. The collecting manifold is made of hexagonal or octagonal sectional surfaces that can withstand internal pressure from thermal expansion and contraction. The resilient portion of the solar panel ensures that the manifold can expand to prevent it from breaking or bursting due to excessive pressure and energy, resulting in a more durable and long-lasting solar panel.

Problems solved by technology

The technical problem the present invention wants to solve is that conventional solar panel is disadvantageous because the heat collecting manifold of the solar panel is made by plastic with a little resilience, however, the sectional surface of the heat collecting manifold is circular, the inner wall thereof cannot effectively sustain the pressure, nor generating a certain force sustaining surface.

Furthermore, the expansion of the heat-collecting manifold may be interfered by the rib piece.

So, when the water in the heat collecting manifold is heated to a certain temperature to generate thermal expansion and contraction thereof, the heat collecting manifold may not expand smoothly, which may cause breaking or bursting of the heating collecting manifold to shorten the service life of the solar panel.
