Abstract
Abstract An improved ozone generator formed from two groups of spaced, interleaved, relatively small reactor plates in a housing. Each of the plates is cooled by a coolant passing through the interior thereof. The coolant is a refrigerant flowing through a refrigeration system for which the plates define the evaporator. Each plate has a ceramic outer coating which provides a dielectric therefor and protects the plate from corrosion. Improved support means for each group of plates includes a pair of tubular mounts formed from fittings which convey the refrigerant to internal passages in the plates, provide the electrical connections thereto, and permit the plates to be coupled together as a modular unit so that the plates can be leak-tested before being placed in the housing. Improved fluid distribution means is provided at the inlet and outlet ends of the housing to assure uniform flow of air into the housing and uniform flow of air and ozone out of the housing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
In an ozone generator: a housing having a fluid inlet end and a fluid outlet end; a plurality of reactor plates; means mounting said reactor plates within said housing in spaced, side by side relationship with respect to each other; and first and second fluid distribution means adjacent to the inlet and the outlet ends, respectively of said housing for permitting a fluid to flow uniformly into spaces between the plates, the second means including means for generating a back pressure in the spaces between the plates before permitting the fluid to flow through the outlet end to facilitate a homogeneous fluid flow past the reactor plates in the housing, the back pressure generating means comprising wall means disposed transversely to the plates and separating a portion of the housing occupied by the plates from the outlet, the wall means including a plurality of openings evenly distributed over the wall means, each opening being of a lesser transverse extent than the outlet.

Claim 3
Dependent Claim
176 words
An ozone generator comprising a housing having a fluid inlet end and a fluid outlet; a plurality of reactor plates disposed within an interior space of the housing; means mounting the reactor plates in the space closely adjacent to each other in an interleaved, spaced relationship with respect to each other to define open passages between the plates which are in fluid communication with each other; and first and second fluid flow control walls mounted transversely to the plates within the housing between the space and the inlet and the outlet, respectively, the first wall including a plurality of evenly distributed openings establishing fluid communication between the inlet and the space for evenly dividing an incoming airstream from the inlet into the passages between the reactor plates, and the second wall including a plurality of evenly distributed openings establishing fluid communication between the space and the outlet for forming a homogeneous back pressure in the passages between the reactor plates, whereby the walls cause a uniform flow of the airstream through all passages between the plates.
