- 29 Abstract The present disclosure discloses a method of forming an ejector for a solar energy system using hydroforming. 5994515_1 (GHMatters) P95411 .AU.1 JMEAD Provide a tube, the tube comprising a material that deforms when at least a length of the tube is exposed to a suitable 12 difference in pressure between an interior portion of the length of the tube and an exterior portion of the length of the tube Provide at least one die having an internal region arranged to receive a length of the tube, the internal region defining a shape 13 that is related to a shape of a nozzle housing and a compressor of an ejector Position the length of the tube in the internal region of the die Partially hydroform the compressor portion and the nozzle housing portion of the ejector by increasing a relative pressure of a fluid within the interior portion of the length of the tube 15 relative to a pressure within the internal region of the die and outside the interior portion of the length of the tube such that at least a portion of the length of the tube expands towards a surface of the internal region of the die Heat the tube so as to remove at least some internal stress from the tube that resulted from the step of increasing the relative pressure of the fluid within the interior portion of the tube Subsequent the heating step, in the or a further die, fully hydroform the compressor portion and the nozzle housing 17 portion of the ejector by increasing the relative pressure of the fluid within the interior portion of the length of the tube relative to a pressure within the internal region of the or the further die and outside the interior portion of the length of the tube such that at least a portion of the length of the tube expands to the nozzle housing portion and the compressor.
