Abstract
Abstract A solar sensor-heater comprising a fluid conduit coiled about a black body enclosed in an insulated container. One side of the container is transparent to allow solar radiation to impinge upon the fluid conduit and black body. A pump is located in the fluid conduit output. A temperature sensing device is located upon the fluid conduit and senses the temperature of the fluid in the conduit and thereby turns the pump on or off as required.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
A solar sensor and heater means comprising fluid conduit means, fluid inlet means and fluid outlet means both interconnected in fluid communicating relation to said fluid conduit means, whereby fluid is directed to and from said fluid conduit means at substantially spaced apart points thereof, black body means including a heat conductive sheet element having a substantially undulating configuration along at least a portion of its length, adjacent and successively disposed predetermined portions of said fluid conduit means positioned in direct engagement with oppositely disposed surfaces of said sheet element, pump means disposed in fluid regulating relation to fluid within said fluid conduit means and temperature sensing/signalling means disposed in temperature sensing engagement with said fluid conduit means and in electrically connected actuating relation with said pump means, whereby fluid flow to and from said fluid conduit means is regulated by activation of said pump means dependent upon the sense temperature of the fluid conduit means.
Claim 2
Dependent Claim
156 words
A solar sensor and heater means comprising fluid conduit means, fluid inlet means and fluid outlet means both interconnected in fluid communicating relation to said fluid conduit means, whereby fluid is directed to and from said fluid conduit means at substantially spaced apart points thereof, black body means including a heat conductive sheet element having a substantially undulating configuration along at least a portion of its length, adjacent and successively disposed predetermined portions of said fluid conduit means positioned in direct engagement with oppositely disposed surfaces of said sheet element, pump means disposed in fluid regulating relation to fluid within said fluid conduit means and temperature sensing/signalling means disposed in temperature sensing engagement with said fluid conduit means and in electrically connected actuating relation with said pump means, whereby fluid flow to and from said fluid conduit means is regulated by activation of said pump means dependent upon the sense temperature of the fluid conduit means.
Claim 3
Dependent Claim
45 words
A solar sensor and heater means as in claim 1 wherein each of said predetermined portions of said fluid conduit means is disposed in direct heat conductive engagement in a trough of said conductive sheet element defined by oppositely disposed surfaces of said sheet element.
Claim 4
Dependent Claim
81 words
A solar sensor and heater means as in claim 1 further comprising base means including a first insulating means and a second insulating means disposed in overlaying relation to said first insulating means, reflector means overlaying at least a portion of said second insulating means, said fluid conduit means disposed at least in part between said reflector means and an under surface of said black body means and in heat conductive engagement with the under surface of said black body means.
Claim 5
Dependent Claim
55 words
A solar sensor and heater means as in claim 1 wherein temperature sensing and signalling means further comprises temperature sensing means located in direct contact with said fluid conduit means and in segregated relation to the fluid within said fluid conduit means, said temperature sensing means disposed in electrically, actuating connection with said pump means.
Claim 6
Dependent Claim
76 words
A solar sensor and heater means as in claim 1 further comprising freeze protection means and boil protection means both disposed in direct heat conductive engagement with said fluid conduit means and each disposed in electrically connected, on and off activating relation with said pump means, whereby operation of said pump means is regulated by the determination of temperature of said fluid conduit means sensed by said boil protection means and said freeze temperature sensing means.
Claim 7
Dependent Claim
28 words
A solar sensor and heater means as in claim 1 wherein said black body means comprises a heat conductive sheet element having solar radiation absorptive means deposited thereon.
