FR2854448A1 - Solar heat energy recuperating device, has sensor resembling ridge tile on roofs or parapet and including hollow body equipped with fins that are fed by coolant passing through connections of inlet and outlet - Google Patents

Abstract

The device has a sensor resembling a ridge tile on roofs or parapet. The sensor has a hollow body (1) equipped with fins (2). A coolant (3) passing through connections (4) of an inlet and outlet, is fed to the fins. The fins transmit solar heat energy captured by the sensor to the coolant. Fixation bars fix the device on a balcony and a ground contact point discharges lightning towards the ground.

Description

The present invention relates to a device to be placed on roofs intended to recover solar thermal energy.
The sensor, object of this invention consists of a hollow monobloc element to be placed in ridge on the roofs or on terrace parapets equipping the roof decks.
According to this invention, this morphology sensor analogous to the ridge tiles replaces the latter.
The originality of this sensor is that it is made up of a hollow body (1) in figure 2 provided with internal fins (2) in figure 2 in which circulates a heat transfer fluid (3) in figure 1.
These sensors are connected in a network by means of flexible pipes on the outlets (4) in Figure 1 in order to ensure the circulation of the heat transfer fluid: entry in (6) in Figure 1; exit in (7) figure 1.
These sensors are placed on the ridge or on the shore and offer the advantage of being fully exposed all day regardless of the position of the sun or the orientation of the roof.
This sensor is fitted inside fins (2) in Figure 1 and (2) in Figure 2, which is the subject of the patent: the heat exchange surface, the speed and the efficiency are increased tenfold.
This sensor can be made in a ferrous, aluminum alloy, magnesium, zinc or other metal foundry. These alloys are cast in gravity or under pressure.
The internal fins are obtained from foundry by coring. The fins can be placed as inserts.
This sensor can be made of glass made of charged or uncharged plastics, baked clay, ceramic, cement.
This solar collector can be treated by electrolysis, anodization for example. Similarly, it can be galvanized, painted, powdered, either to guarantee corrosion or to increase the capture of solar calories, or for decorative purposes.
The accompanying drawings illustrate this invention.
Figure 1 page 1 of 2 shows in section the sensor object of the invention. Figure 2 page 1 of 2 shows the sensor according to section A / A. Figure 3 page 2 of 2 shows a perspective view of the outside of the sensor. Figure 4 page 2 of 2 shows a view with the interior of the sensor in dotted lines.
According to the latter, this device comprises transverse fixing locations (8) in FIG. 4 supplemented by (5) in FIG. 1 as well as (9) in FIG. 3.
This sensor is equipped according to (8) FIG. 3 with a positioning point for the balcony foot.
This sensor is equipped with a ground contact pad (10) in Figure 3 to evacuate lightning towards the ground via a conductor.
Outlets (4) in Figure 1, at the inlet and outlet ensure the passage of the coolant.
The heat transfer fluid circulates around the fins from (6) Figure 1 to (7) Figure 1 according to the arrow diagram.
A thermal probe, to control the temperature of the heat transfer fluid placed in (11) according to figure 1, visible in (11) figure 2.

Claims (1)

2 - Device according to claim 1 characterized in that it is equipped with fixing for balcony 8 and earth contact sockets 10 for discharging lightning towards the ground by a conductor.
