Definitions
- the present invention relates to a new method for manufacturing of heat exchangers, and more particularly to a method of producing complete integrated heat exchanger units (modules) of variable size and capacity, and also to heat exchangers produced by such method.
- German laid open patent application AS 2 046 770 discloses a classical heat radiator comprising two manifold pipes and several parallel running circulation tubes between these manifold pipes attached metallic sheets in order to increase the heat rejection.
- the metallic sheets (covers) are designed as a shutter providing a possibility of influencing the direction of the circulating air current through the radiator.
- the connection between the pipes and the shutter is ensured by means of screws, clamps etc., which means high production and assembling costs.
- German utility model No. 1.714.347 discloses a heat exchanger comprising a meander-like bent pipe provided with coextruded single webs partly removed in the U-bend area in order to facilitate manufacturing of the heat exchangers.
- the disclosed heat exchanger is limited to the shown embodiment and does not provide possibility of forming circulation channels between the parallel running tube parts. Furthermore, there is no possibility for an easy way of connecting the web parts together and/or to cover the U-bends.
- US Patent No. 2.578.305 relates to a heat exchanger tube for exposure to gases that flow transversely of its longitudinal axis.
- the tube is provided with symmetrically disposed longitudinally extending fins projecting from the tube surface in planes at either side of the axis and formed in the edge portions thereof in contact with the tube. Furthermore, the fins are provided with slots that form with the tube surface passages converging in the direction of the flow toward the space between the fins.
- the disclosed tube design and configuration of fins will not give a possiblity of bending the tube in a meander-like path and form integrated circulation chambers. Furthermore, there is no flexibility in the design with regard to the possibility of bending the tube in other directions than parallel to the fin's projection.
- German Patent No. 831263 discloses a heat exchanger comprising a bundle of pipes provided with longitudinally extending fins welded to the pipe surface and forming vertical channels of variable cross-sections.
- the object of the present invention is to provide an improved method for manufacturing of heat exchangers resulting in integrated, one-piece, jointless heat exchanging modules having a multiplicity of channels for external circulation of the heat exchanging medium, e.g: air, outside the tubes constituting a circulation loop for the heating medium.
- the heat exchanging medium e.g: air
- Another object of the invention is to provide a method of manufacturing heat exchangers ensuring flexibility with regard to the possibility of bending the circulation tube in desired angles in relation to the fin's projection and furthermore, that the U-bend parts of the circulation tube are completely withdrawn (hidden) behind the front panel of the heat exchangers formed by attached fins.
- Still another object of the invention is to provide compact, jointless heat exchanger modules having longitudinally extending channels formed by fins attached to the circulation tubes and transversal apertures in the fins, ensuring an optimal heat rejection performance.
- Figs. 7 and 8 are particularly useful when different cooling/heating loops for different media and/or heat exchanging media in the chambers are applied.
- Fig. 9 illustrates a typical and advantageous application of the heat exchanging modules (1) according to the invention for providing of compact heat exchangers for automotive purposes of desired size/capacity.
- Fig. 10 shows more clearly in a cross-sectional view the hollow shape (2) applied in the module shown in Fig. 9 with a special configuration of fins (22) surrounding the tube (21) which allows bending of the shape in different directions (x,y) assuring formation of a multiplicity of circulation chambers (24) between a pair of adjacent fins (see Fig. 9).
- This module comprises units displaced and connected in a 90° angle in relation to each other by bending of the tube (21,21') in different directions.
- the present invention is not limited to the disclosed, and in connection with the accompanying drawings described embodiments and/or applications of the heat exchanging modules and can be used e.g. for manufacturing of electrically heated radiators by embedding a resistant wire into the meander folded tube. Such application will result in a substantial reduction of production and material costs.
