Abstract
A method for manufacturing a structural surface heat exchanger of preset or left-hand final shape for an aircraft includes the steps of forming, shaping and assembling, by welding or brazing, a first corrugated skin and a second smooth skin in order to obtain channels. Each channel is delimited by a corrugation of the first skin and the second smooth skin so as to form a structural surface heat exchanger of preset or left-hand final shape, wherein a fluid is configured to circulate in the channels and air is configured to circulate in contact with the second smooth skin.

A method for manufacturing a structural surface heat exchanger of an adjusted or left final shape for an aircraft, the method comprising:
- forming a first skin to obtain a first corrugated skin;
- shaping and assembling the first corrugated skin and a second smooth skin so that the first corrugated skin and the second smooth skin define channels, each channel being delimited by the second smooth skin and a corrugation of the first corrugated skin, wherein assembling the first corrugated skin and the second smooth skin includes welding or brazing the first corrugated skin to the second smooth skin, wherein shaping and assembling the first corrugated skin and the second smooth skin forms the structural surface heat exchanger of an adjusted or left final shape, configured to permit a fluid to circulate in the channels and air to circulate in contact with the second smooth skin;
- and
- forming cavities in the first skin simultaneously with the step of forming the first skin to obtain the first corrugated skin, or in the second smooth skin prior to the step of shaping the second smooth skin or assembling the first corrugated skin on the second smooth skin, to obtain fluid distributors and collectors when assembling the first corrugated skin and second smooth skin, wherein the step of forming cavities includes forming the cavities by operation of a press or by machining the first corrugated skin or the second smooth skin.
A method of manufacturing a structural surface heat exchanger of an adjusted or left final shape, the method comprising:
- a. forming a first skin to obtain a first corrugated skin;
- b. shaping the first corrugated skin obtained in step (a) to obtain a first corrugated skin of an adjusted or left final shape;
- c. shaping, via tensioning, a second smooth skin to obtain a second smooth skin of an adjusted or left shape;
- and
- d. assembling the first corrugated skin of the adjusted or left final shape and the second smooth skin of the adjusted or left shape obtained in steps (b) and (c) to obtain channels, each channel being delimited by a corrugation of the first corrugated skin of the adjusted or left final shape and the second smooth skin of the adjusted or left shape, so as to form the structural surface heat exchanger of the adjusted or left final shape, in which a fluid is configured to circulate in the channels, and air is configured to circulate in contact with the second smooth skin.
A method of manufacturing a structural surface heat exchanger of an adjusted or left final shape, the method comprising:
- a. forming, via a press, a first skin to obtain a first corrugated skin;
- b. assembling the first corrugated skin obtained in step (a) on a second smooth skin to obtain channels, each channel being delimited by the second smooth skin and a corrugation of the first corrugated skin, so as to form a structural surface heat exchanger of right intermediate shape;
- and
- c. shaping the structural surface heat exchanger of the right intermediate shape obtained in step (b) to obtain the structural surface heat exchanger of the adjusted or left final form between a fluid configured to circulate in the channels, and air configured to circulate in contact with the second smooth skin.
