Exchanger body and exchanger

An exchanger body comprising:

• (i) at least one chamber housing at least one exchanger body, said at least one chamber acting as a guiding envelope to guide a flow of a first fluid in or towards the exchanger body adapted to exchange heat between said first fluid and a second fluid, said exchanger body comprising:
• an element adapted to be situated at least partially in this guiding envelope, this element consisting of a first sheet defining a first face of the element and a second sheet defining a second face of the element, said first and second sheets being made of a heat conducting material and having each a first longitudinal edge and a second longitudinal edge, these first and second sheets being connected to each other at least in the vicinity of their first longitudinal edges for defining a first longitudinal edge of the element and in the vicinity of their second longitudinal edges for defining a second longitudinal edge of the element, whereby defining at least one internal channel for this second fluid in the element between said first and second longitudinal edges of the element, this element being wound to form a structure at least partially in a spiral extending into this guiding envelope, said spiral defining at least one outer channel for the first fluid between the first face and the second face of the element wound to form a structure at least partly in a spiral,
• at least one substantially radial distributor extending along a radial direction to convey this second fluid in the element in the vicinity of the first longitudinal edge of the element at the level of portions of the first longitudinal edge of the element wound to form a structure at least partly in a spiral, said portions extending along the radial direction of the at least one distributor, and at least one substantially radial collector extending along a radial direction to collect this second fluid after its passage in this element, this collector being adapted to collect this second fluid in the vicinity of the second longitudinal edge of the element at the level of portions of the second longitudinal edge of the element wound to form a structure at least partly in a spiral which are extending along the radial direction of the at least one collector, in which the first sheet and the second sheet forming the element are deformed to form a first series of channels and a second series of channels respectively, the edge of the channels of the first series of the first sheet turned towards the second sheet contacting the edge of the channels of the second series of the second sheet, forcing this second fluid to follow a path between the distributor and the collector, this path being formed by both the channels of the first series and the channels of the second series,
• and (ii) at least one distributing means for distributing the first fluid into the outer channel defined by the spiral of the exchanger body.

Process for transferring heat energy selected form the group consisting of calories or and frigories between at least a first fluid and a second fluid by means of an exchanger comprising:

• (i) at least one chamber housing at least one exchanger body, said at least one chamber acting as guiding envelope to guide a flow of a first fluid in or towards the exchanger body adapted to exchange heat between said first fluid and a second fluid, said exchanger body comprising:
• an element adapted to be situated at least partially in this guiding envelope, this element consisting of a first sheet defining a first face of the element and a second sheet defining a second face of the element, said first and second sheets being made of a heat conducting material and having each a first longitudinal edge and a second longitudinal edge, these first and second sheets being connected to each other at least in the vicinity of their first longitudinal edges for defining a first longitudinal edge of the element and in the vicinity of their second longitudinal edges for defining a second longitudinal edge of the element, whereby defining at least one internal channel for this second fluid in the element between said first and second longitudinal edges of the element, this element being wound to form a structure at least partially in a spiral extending into this guiding envelope, said spiral defining at least one outer channel for the first fluid between the first face and the second face of the element wound to form a structure at least partly in a spiral,
• at least one substantially radial distributor extending along a radial direction to convey this second fluid in the element in the vicinity of the first longitudinal edge of the element at the level of portions of the first longitudinal edge of the element wound to form a structure at least partly in a spiral which are extending along the radial direction of the at least one distributor, and at least one substantially radial collector extending along a radial direction to collect this second fluid after its passage in this element, this collector being adapted to collect this second fluid in the vicinity of the second longitudinal edge of the element at the level of portions of the second longitudinal edge of the element wound to form a structure at least partly in a spiral which are extending along the radial direction of the at least one collector, in which the first sheet and the second sheet forming the element are deformed to form a first series of channels and a second series of channels respectively, the edge of the channels of the first series of the first sheet turned towards the second sheet contacting the edge of the channels of the second series of the second sheet, forcing this second fluid to follow a path between the distributor and the collector, this path being formed by both the channels of the first series and the channels of the second series,
• and (ii) at least one distributing means for distributing the first fluid into the at least one outer channel defined by the spiral between the spirals of the exchanger body,
• in which the first fluid is conveyed in the at least one outer channel defined by the spiral, and
• in which the second fluid is distributed via at least one distributor in the at least one internal channel of the element in the vicinity of a first longitudinal edge of the element and
• in which the second fluid is collected after its passage in the at least one internal channel of the element via the at least one radial collector.
