Abstract

A collector panel for a solar water heater comprises two identical metal pressings 12 formed with a plurality of spaced apart channel formations 14 which form tubes when the pressings are mated with the formations in register. The pressings are joined together along the flat portions 16 between the channel formations. Transverse channel formations are provided at the ends of the channel formations 14 and are arranged to be in register to form manifolds connecting the ends of the channel formations 14 when the pressings are mated. An upper glass cover 26 supported by a frame 28 and lower insulation 24 are provided. <IMAGE>

Description

SPECIFICATION Solar heater and component therefor This invention relates to solar heaters and in particular to a collector panel for a solar water heater.
According to the invention a heat collector component for a solar heater comprises a pair of substantially planar elements formed with a plurality of spaced apart channel formations arranged to form tubes when the elements are mated with the formations in register, the elements being adapted to be joined together along the portions between the channel formations.
In the preferred form of the invention the channel formations are parallel to one another, the elements being formed with transverse channel formations at the ends of the channel formations and the transverse channel formations being arranged to be in register to form manifolds joining the ends of the tubes together when the elements are mated.
The components- may be substantially identical one to the other and comprise metal pressings.
The transverse channel formations in the elements may be of a lesser depth than the channel formations, the ends of which are tapered to accommodate the transverse channel formations.
An example of the invention is described with reference to the accompanying drawings in which: Figure 1 is an isometric view of two components joined together to form the collector of a heat exchanger; and Figure 2 is a sectional view on arrows B-B in Figure 1.
In the drawings the collector 10 is made up of two elements in the form of identical metal pressings 12. Each pressing comprises a series of spaced parallel hemicylindrical channel formations 14 with flat portions 1 6 therebetween and further flat portions 18 coplanar with the portions 1 6 around the entire pressing. The channels 14 are joined by transverse channel formations 20 formed at each end of the channels 14. Short channel formations 22 project outwardly in the longitudinal direction from the channels 20.
The pressings 12 being identical can be mated up with the flat portions joined face to face and the channels 14, 20 and 22 in register and constituting longitudinally extending tubes joined at their ends by manifolds, the tubes being formed by the channels 14 and the manifolds by the channels 20. The channels 22 constitute an inlet and an outlet from the two manifolds.
The transverse channel formations 20 are shallower than the channel formations 14 and the ends of the channels 14 are tapered to accommodate the shallower formations 20. It has been found that the tapered portions improve the heating capacity of the collector due to the smaller volume of water in those portions and hence the greater ratio of surface area to volume.
The components constitute a collector which is provided with insulation 24 on its lower face and a glass cover 26 supported by a frame 28 over its upper face. The assembly constitutes an efficient and extremely cheap solar heater unit the operation of which will be self evident to the man skilled in the art.
1. A heat collector component for a solar water heater comprising a pair of substantially planar elements formed with a plurality of spaced apart channel formations arranged to form tubes when the elements are mated with the formations in register, the elements being adapted to be joined together along the portions between the channel formations.

A component according to claim 1 in which the channel formations are parallel to one another the elements being formed with transverse channel formations at the ends of the channel formations and the transverse channel formations being arranged to be in register to form manifolds joining the ends of the tubes together when the elements are mated.
