Abstract
Abstract A surface condenser particularly suitable for being used in a zero gravity environment and which is easy to be manufactured. It comprises at least one pair of coextensive elements spaced apart from each other to form a relatively narrow gap therebetween, said gap having a width which is tapered from the outer ends of said elements towards a defined portion thereof. Peripheral distributor means extends along the outer ends of the elements and has its interior space in communication with the gap at the larger width side thereof, said distributor means having an inlet for the vapor to be condensed. Collector means is provided in communication with the interior space of the gap at the smaller width side thereof for collecting the condensed liquid.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
Condenser apparatus comprising: at least one pair of coextensive elements spaced apart from each other to form a relatively narrow gap therebetween, said gap having a width which is tapered from the outer ends of said elements towards a defined portion thereof; peripheral distributor means extending along the outer ends of said elements and having its interior space in communication with the said gap at the larger width side thereof, said distributor means having an inlet for the vapor to be condensed; and collector means for collecting the condensed liquid at said defined portion of the elements, said collector means being in communication with the interior space of the gap at the smaller width side thereof.
Claim 2
Dependent Claim
116 words
Condenser apparatus comprising: at least one pair of coextensive elements spaced apart from each other to form a relatively narrow gap therebetween, said gap having a width which is tapered from the outer ends of said elements towards a defined portion thereof; peripheral distributor means extending along the outer ends of said elements and having its interior space in communication with the said gap at the larger width side thereof, said distributor means having an inlet for the vapor to be condensed; and collector means for collecting the condensed liquid at said defined portion of the elements, said collector means being in communication with the interior space of the gap at the smaller width side thereof.
Claim 3
Dependent Claim
52 words
A condenser apparatus according to claim 1, wherein there are provided means for creating passages adjacent the external surfaces of said elements, said passages being connected to a coolant fluid inlet and a coolant fluid outlet for permitting the circulation of the coolant fluid in heat exchange relation with the condensed fluid.
Claim 4
Dependent Claim
70 words
A condenser apparatus according to claim 1, wherein there are provided a plurality of pairs of spaced apart coextensive elements, the gap between the elements in each pair having a width which is tapered from the outer ends of the elements towards a defined portion thereof, the gaps being connected at their larger width side to said peripheral distributor means and at their smaller width side to said collector means.
Claim 5
Dependent Claim
50 words
A condenser apparatus according to claim 3, further comprising means for creating passages adjacent the external surfaces of said elements, said passages being connected to a coolant fluid inlet and a coolant fluid outlet for permitting the circulation of the coolant fluid in heat exchange relation with the condensed fluid.
