Description

The Corrugated Solar Collector is a manufactured panel (factory built) and may be categorized as an active solar collector used in a solar heating system. Active solar collectors are utilized to absorb the maximum incoming solar energy and to conduct this energy to a transport medium, with minimum loss by conduction, convection, re-radiation, and reflection.
The key element of any active solar heating system is the solar collector.
The invention relates to a manufactured panel that can act as a solar energy collector for converting solar energy into usable energy; it can be utilized for transferring energy from conditioned space to a non-conditioned space; and, it can be utilized for transferring energy from a non-conditioned space to a conditioned space. In the particularly advantageous embodiment of the invention a transport medium flows through the first connecting tube into the inlet header. The transport medium then flows through inlet tubes into a hermetically sealed unit utilizing a series of inlet tubes attached perpendicular to the inlet header. The inlet tubes are placed at various intervals providing an even distribution of transport medium across the corrugated collector plate surface. The corrugated collector plate surface plurality of ridges and groves are perpendicular to the flow of transport
2 medium and parallel to the inlet header and outlet header. Energy is converted from non-usable energy to usable energy in the primary collector chamber and is transported by the transport medium out of the hermetically sealed unit through a series of outlet tubes attached to the outlet header.
The outlet tubes are perpendicular to the outlet header. The transport medium enters the outlet header and flows through the outlet header into the second connecting tube.
The first connecting tube and second connecting tube are advantageously interchangeable and can be straight or have multiple bends and vary in length. Female connectors at either end of the first connecting tube and second connecting tube advantageously allow quick connection and release of the manufactured panel in series, parallel, series-parallel, or reverse-return piping systems and for the connection to the return/supply lines.
The inlet header is located at the edge of the hermetically sealed unit. The inlet header has male connectors at each end advantageously allowing quick connection and release of the manufactured panels and is connected to the first connecting tube, inlet tubes, and frame assembly.

Inlet tubes are attached to inlet header such that the attachment of the inlet tubes to the inlet header and the attachment of the inlet tubes to the spacer assembly to advantageously permit the flow of the transport medium from the inlet header into the primary collector chamber. Inlet tubes are attached to the inlet header in a straight line and are advantageously spaced at various intervals to provide an even distribution of transport medium across the corrugated collector plate surface. The even distribution of the transport medium advantageously optimizes the heat transfer capabilities as the transport medium is in contact with the entire surface of the corrugated collector plate surface.
The hermetically sealed unit has two transparent layers, layer one and layer two and a third layer, layer three that is opaque. Layer two and layer three is bonded with a spacer assembly placed on the perimeter of the layers to form the primary collector chamber and contain the corrugated collector plate.
Layer one is used to form the secondary collector chamber. The primary collector chamber has a spacer assembly that advantageously sets apart layer two and layer three to provide for the containment of the corrugated collector plate and transport medium while optimizing the thermal performance of the primary collector chamber. The spacer assembly is bonded to the perimeter edge of layer two and layer three and the outer edge of the corrugated collector plate. The secondary collector chamber is comprised of layer one that is bonded on its perimeter to an insulating spacer assembly and advantageously can contain a fill gas to improve the thermal performance of the hermetically sealed unit. The insulating spacer assembly is bonded to perimeter edge of layer two creating the secondary collector chamber. The insulating spacer assembly and secondary collection chamber advantageously reduces convection, conduction, and radiant heat loss from the primary collector chamber. Layer one and layer two can be coated with spectrally selective coatings that advantageously increase or decrease certain solar wavelength bands. Spectrally selective coatings on layer one and layer two can be used advantageously to increase or decrease conduction and radiation heat loss and heat gain. A backing seal is applied advantageously to the edge of the hermetically sealed unit as a secondary seal for containment of the gas fill. The hermetic seal and backing seal of the hermetically sealed unit advantageously allows the manufactured panel to operate under pressure and can achieve a high rate of solar energy collection efficiency for high temperature applications. The hermetic seal and backing seal of the hermetically sealed unit advantageously allows the manufactured panel to utilize a gas or fluid as the transport medium. The corrugated collector plate surface plurality of ridges and groves are perpendicular to the flow of the transport medium and parallel to the inlet header and outlet header advantageously creating a turbulent flow of the transport medium optimizing the energy transfer from the corrugated collector plate to the transport medium. The surface of the corrugated collector plate has high absorptivity to short wavelengths of the solar spectrum, low-emissivity at long wavelengths to minimize re-radiation of absorbed energy, and has good thermal conductivity for the transfer of heat to the transport medium. The ridges and groves are advantageously shaped to optimize the collection of solar energy and to maximize the surface area of the corrugated collector plate in the primary collector chamber. The corrugated collector plate is contained in the primary collector chamber and is advantageously bonded to the spacer assembly. The first grove of the first ridge is advantageously bonded to the spacer assembly and positioned to allow for the flow of transport medium into the primary collector chamber. The last grove of the last ridge is bonded to the spacer assembly and advantageously positioned to provide for the flow of transport medium out of the primary collector chamber. The bonding of the first grove of the first ridge and the last grove of the last ridge to the spacer assembly is identical and advantageously creates a trough that allows for the collection of the transport medium at the mouth of the outlet tubes. The shape of each ridge is identical and the shape of each groove is identical. The bonding of the first grove and the last grove to the spacer assembly is identical. The bonding of the outer edges of the corrugated collector plate to the spacer assembly is identical for each edge.
The spacing and attachment of the inlet tubes and outlet tubes to the spacer assembly is identical. The shape of each ridge and grove and the bonding of the perimeter edge of the corrugated collector plate and first grove and the last grove to the spacer assembly and the spacing and attachment of the inlet tubes and outlet tubes to the spacer assembly is particularly advantageous to the orientation of the corrugated collector plate during the installation in the primary collector chamber as the first grove or the last grove can be installed at either the outlet or inlet edge of the primary collector chamber. The configuration and positioning of the corrugated collector plate advantageously optimizes the collection of solar energy with respect to the angle of the sun and the available surface area of the corrugated collector plate as the path of the sun crosses the manufactured panel or the manufactured panel follows the path of the sun.
The outlet tubes are attached to the outlet header such that the attachment of the outlet tubes to outlet header and the attachment of the outlet tubes to the spacer assembly to advantageously permit the flow of the transport medium from the primary collector chamber into the outlet header. The outlet tubes are attached to the outlet header in a straight line and are spaced at various intervals to advantageously provide a flow of transport medium across the corrugated collector plate surface into the outlet header.
The design of the outlet header is identical to the inlet header and particularly advantageous as it can be interchanged one for the other. The outlet header is located at the edge of the hermetically sealed unit. The outlet header has male connectors at each end advantageously allowing quick connection and release of the manufactured panel and is connected to the second connecting tube, outlet tubes, and frame assembly of the manufactured panel.

The frame assembly provides an interface between the hermetically sealed unit and the mounting surface. The frame assembly advantageously creates a method of shedding rain off the manufactured panel and provides thermal protection with the containment of insulating material that abuts five sides of the six sided hermetically sealed unit. The frame assembly advantageously supports the inlet header and outlet header. The particularly advantageous material of the frame assembly is an extruded polymer that is resistant to ultra violet degradation and can be easily assembled. The mounting flange is used advantageously for the attachment of the manufactured panel to the mounting surface and acts as a flashing for shedding rain. The assembled manufactured panel inlet and outlet ends are identical and the panel can be mounted on an incline, horizontal, or rotating surface to advantageously accommodate reverse directional flows of the transport medium.
