Abstract

Abstract The condenser comprises a pair of flow headers (10,12), one of which has a vapour inlet whilst the other has a condensate outlet (26). Flattened distribution tubes (20) between the headers define discrete hydraulically parallel fluid pathways. Each fluid pathway has an hydraulic diameter between 0.015 to 0.040 inches. There are several condenser tubes each extending between and in fluid communication with the headers.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 124 words
An air cooled condenser suitable for use in a refrigeration or air conditioning system to condense a refrigerant vapour into a refrigerant liquid, the condenser comprising a pair of spaced headers (10,12) for receiving refrigerant vapour and collecting condensed refrigerant; and a plurality of tubes (20) extending in hydraulic parallel between said headers, each tube being in fluid communication with each said header and being elongate in transverse cross-section with the minor dimension of the cross-section aligned substantially perpendicular to the direction of air flow through the condenser, characterised in that each said tube defines a plurality of discrete hydraulically parallel fluid flow paths, each said fluid flow path having a hydraulic diameter in the range of 0.381 to 1.778mm (0.015 to 0.070 inches).
Claim 2
Dependent Claim 32 words
A condenser according to claim 1 wherein said tubes are flattened tubes and the plurality of flow paths in each tube is defined by an undulating spacer (40) contained within the tube.
Claim 3
Dependent Claim 20 words
A condenser according to claim 1 or claim 2 further including fins (34) on the exteriors of said condenser tubes.
Claim 4
Dependent Claim 21 words
A condenser according to any preceding claim including fins (34) extending between the exteriors of adjacent ones of said condenser tubes.
Claim 5
Dependent Claim 30 words
A condenser according to any preceding claim wherein said headers are defined by generally cylindrical tubes and have facing openings (14) for receiving respective ends 16,18) of said condenser tubes.
Claim 6
Dependent Claim 50 words
A condenser according to claim 5 wherein said openings are a series of elongated slots (14), the slots on one header tube facing the slots on the other header tube; and wherein the condenser tubes are flattened tubes (20) having opposed ends (16,18) disposed in corresponding ones of said slots.
