Method for producing heat exchanger elements, heat exchanger elements and method for assembling such elements
View Patent ↗A heat exchanger panel for a surface of a room, the panel having plate-type heat exchanger elements and having a heat exchanger pipe. The heat exchanger elements include two main surfaces facing away from each other and a peripheral surface linking the main surfaces, a fiber mat and a thin plaster layer. The plaster layer adheres to the fiber mat and the heat exchanger pipe extends at least partially within the plaster layer. The pipe has at least two connections in the area of the peripheral surface.
1. A method for assembling heat exchanger elements including a fibrous mat, wherein the fibrous mat has a thickness of at least 25 mm and includes fibers which are interconnected by a bonding agent, and at least one heat exchanging conduit for a heat exchanging medium, the heat exchanger elements being panel shaped and including at least two main surfaces averted from each other and a peripheral surface connecting the main surfaces, the method comprising:
attaching at least two heat exchanger elements adjacent to each other, to a room delimiting surface, wherein uncoated main surfaces of the fibrous mats are glued to said room delimiting surface, and
in a first step, a first row of heat exchanger elements are fastened with their first lateral surfaces situated side by side,
in a second step, holding elements are mounted to join the second side surfaces,
in a third step, a second row of heat exchanger elements are fastened so as to join said holding elements and their first side surfaces engaging each other,
in a fourth step, the two branch necks of each heat exchanger element are connected to a heat exchanger circuit,
in a fifth step, a cast mixture is applied over the heat exchanger elements and the at least two branch necks so that a substantially flat cast surface is obtained, wherein a thickness of the cast mixture is in a range of 2 to 8 mm and the at least one heat exchanging conduit is contained in the cast mixture, and wherein the cast mixture together with the at least one heat exchanging conduit, adheres to the fibrous mat.
2. The method as claimed in claim 1 , wherein
in a sixth step, a flat surface is obtained by grinding, and
in a seventh step, a cover coating is applied.
3. A method for assembling heat exchanger elements including a fibrous mat, wherein the fibrous mat has a thickness of at least 25 mm and includes fibers which are interconnected by a bonding agent, and at least one heat exchanging conduit for a heat exchanging medium, the heat exchanger elements being panel shaped and including at least two main surfaces averted from each other and a peripheral surface connecting the main surfaces, the method comprising:
attaching at least two heat exchanger elements adjacent to each other, to a room delimiting surface, wherein uncoated main surfaces of the fibrous mats, for fastening the heat exchanger elements, are glued to said room delimiting surface, wherein
in a first step, a first row of heat exchanger elements are fastened with their first lateral surfaces situated side by side, while spacer elements project from their second lateral surfaces,
in a second step, a second row of heat exchanger elements, their first lateral surfaces engaging each other, are fastened so that they join said second lateral surfaces and are spaced by spacer elements,
in a third step, the two branch necks of each heat exchanger element are connected to a heat exchanger circuit,
in a fourth step, covering elements are arranged at the spacer elements,
in a fifth step, a cast mixture is applied at least in regions with gaps over the heat exchanger elements and the at least two branch necks so that a substantially flat cast surface is obtained, wherein a thickness of the cast mixture is in a range of 2 to 8 mm and the at least one heat exchanging conduit is contained in the cast mixture, and wherein the cast mixture together with the at least one heat exchanging conduit, adheres to the fibrous mat.
4. The method as claimed in claim 3 , wherein
in a sixth step, a flat surface is obtained by grinding, and
in a seventh step, a cover coating is applied.
5. A method for assembling heat exchanger elements including a fibrous mat with a thickness of at least 25 mm and including fibers which are interconnected by a bonding agent, the heat exchanger elements being panel shaped and including at least two main surfaces averted from each other and a peripheral surface connecting the main surfaces, at least one heat exchanging unit with two parallel extending longitudinal channels each with a male and a female connector for a heat exchanging medium and a cast coating layer on one of the main surfaces of the fibrous mat, the method comprising:
attaching at least two heat exchanger elements adjacent to each other, to a room delimiting surface,
the uncoated main surfaces of the fibrous mats of the heat exchanger element are glued to said room delimiting surface, and the two male connectors of subsequently mounted heat exchanger elements are plugged into corresponding female connectors, of adjacent heat exchanger elements; and
applying a cast mixture over the heat exchanger elements and the connectors so that a substantially flat cast surface is obtained, wherein a thickness of the cast coating is in a range of 2 to 8 mm and the at least one heat exchanging conduit is contained in the cast coating, and wherein the cast coating together with the at least one heat exchanging conduit, adheres to the fibrous mat.
