Abstract
A heat exchanger includes two mutually isolated fluid circuits in close thermal contact, a first fluid circuit, or bundle (3), consisting of a helical winding of two walls and the second circuit consisting of a chamber containing the bundle (3), each circuit including its own fluid input and output elements. The heat exchanger is characterized in that the bundle is elastically deformable under the effect of excess pressure or low pressure.

A heat exchanger comprising two mutually isolated fluid circuits in intimate thermal exchange contact, a first fluid circuit, or bundle (3) being formed by a helical winding of two walls and the second circuit being formed by an chamber containing the bundle (3), each circuit including its own fluid input and output means, characterized in that the bundle is elastically deformable under the effect of excess pressure and low pressure.
A method for intervening, such as notably for cleaning, on a bundle of a heat exchanger of the helical type including two mutually isolated fluid circuits in intimate thermal exchange contact, a first fluid circuit being formed by a helical winding of two walls, or bundle, and the second circuit being formed by a space delimited by a casing containing the bundle, each circuit including its own fluid input and output means, characterized in that it includes the steps of:
- submitting, before its removal, the bundle to low pressure and/or cooling relatively to its casing, so as to cause it to contract,
- setting back the bundle to pressure and/or room temperature once it has been extracted from its casing, in order to cause it to recover its initial dimensions,
- proceeding with intervention on the bundle,
- again submitting the bundle to low pressure and/or cooling relatively to its casing, in order to cause it to contract before it is placed in the casing,
- setting back the bundle to pressure and/or room temperature once it has been placed back in its casing.
