Description

[Detailed description of the invention] This invention receives radiant heat from various heat sources.
This is transferred to a heat transfer liquid such as water to perform heat exchange.
This relates to the housing structure of the radiant heat collector.

The illustrated embodiment illustrates a specific example of the housing structure according to the present invention.

A first spacer member 1 is interposed between the heat-receiving plate 2 and the bottom member 3, and is located at the periphery of at least three sides of the heat-receiving plate 2 and the bottom member 3 to maintain a distance therebetween, thereby forming a housing 4.

On the other hand, a second spacer member 5 is interposed between the transparent cover 6 and the heat receiving plate 2, and is located at the periphery of the transparent cover 6 and the heat receiving plate 2 to maintain a distance between them.

The second spacer member 5 has an upper flange 5a on which the transparent cover 6 is placed, and a lower flange 5b in contact with the first spacer member 1 at the lower part. The second spacer member 5 passes through the heat receiving plate from the upper flange 5a to the first spacer member while holding the periphery of the heat receiving plate 2 between the lower flange 5b in contact with the first spacer part. The second spacer member is fixed to the first spacer member through a fixing means such as a nail (the illustrated example) or a screw.

On the other hand, the first spacer member 1 is integrated with the bottom member 3 at a portion in contact with the bottom member by means of fixing means such as nails or screws (illustrated examples) passing through the bottom member.

A transparent cover 6 is placed on the upper flange 5a of the second spacer member 5. The transparent cover, in the illustrated example, is a polyethylene film that is attached at the edges in any manner around the exterior of the collector housing.

For reference, in the upper position of the case,
A supply means 7 for supplying heat medium liquid to the inner surface of the heat receiving plate is provided. In the illustrated example, this supply means uses a pipe with holes drilled at appropriate intervals. However, the supply means is not limited to the illustrated configuration. Spray nozzles, gutters, etc. can also be used.

In addition to this water supply means, a rectifying means 8 is located above the housing and is disposed in a direction across the heat receiving plate, forming a small gap between it and the heat receiving plate. By configuring as described above, the supply means 7
The heat medium liquid discharged from the heat transfer plate 2 passes between the rectifying means 8 and the heat receiving plate 2 . At this time, the heat transfer liquid is subjected to resistance, and in areas where there is a large amount of water, the water is spread out laterally. The gap between the heat receiving plate and the rectifying means through which the heat medium liquid passes does not need to be provided continuously in the lateral direction.
Rather, it is more practical to provide gaps intermittently. Alternatively, a fiber layer may be applied to the tip of the rectifying means so as to contact the heat receiving plate through the fiber layer.

Due to the rectifying action of the rectifying means, the heat transfer liquid that has passed through the rectifying means is spread laterally in a thin layer or finely divided, uniformly covering the entire surface of the heat receiving plate, and being densely distributed. Therefore, the heat held by the heat receiving plate is quickly transferred to the flowing heat medium liquid. The heat-absorbing medium liquid that has flowed down is discharged to the outside through an opening (not shown) at the bottom of the housing.

The collector according to the present invention is not limited to the configuration described above. As shown in FIG. 2, it is also possible to attach reinforcing ribs 3a to the periphery of the bottom member, or to attach an auxiliary heat insulating material 3b to the back surface of the bottom member.

By configuring as described above, it can be assembled easily and quickly in a factory or on-site by simple work that does not require special skill, and the collector's external shape and size can be designed relatively freely according to the convenience of the installation site. It has the advantage of being able to It can be manufactured at a very low cost, especially for solar heat,
When used as a collector, its economic effect is quite significant.
