Definitions
- the present invention relates to a foil arrangement in a plate heat- exchanger.
- a heat-exchanger is generally in the shape of a cube formed by a frame.
- the flat and corrugated foils are arranged alternately within the cube.
- the corrugated foils located on top of each other are arranged so that the direction of one foil deviates by 90 from the direction of the foils located above and below it.
- a flat foil must first be inserted, then a corrugated foil, followed by a flat foil, and so on. This procedure is tedious and time- consuming. Furthermore, it is difficult to ensure satisfactory sealing at the edges of a flat and corrugated foil which are parallel to the direction of flow.
- the object of the present invention is to eliminate the drawbacks mentioned above and this is done by using a single blank, not divided into several parts, to form a unit consisting of both a flat and a corrugated foil.
- the starting blank consists of a rectangular foil with three consecutive fields, the middle field being flat and the other two fields corrugated.
- a blank of this type can be produced in a machine.
- the corrugated fields of the blank thus produced are folded towards each other so that the free end edges of the latter fields are in contact with each other and are joined in some manner.
- the two corrugated fields may be of equal or unequal length.
- the middle field may constitute the corrugated part and the end fields the flat parts.
- the edges of the flat parts are joined together.
- Meeting edges may be joined together in various ways, such as by welding, glueing, riveting or the like. Meeting edges in the preceding alternative may also be just located opposite each other, either spaced or in contact with each other.
- the foils should preferably be of aluminium. Other materials are also possible, such as cardboard, plastic, pasteboard. Additional characteristics of the present invention are revealed in the following claims.
- Figure 1 shows a blank for manufacture of a unit for a plate heat- exchanger
- Figure 2 shows the blank being folded
- Figure 3 shows the finished unit.
- the blank shown in Fig.1 has been obtained by passing a sheet of plastic foil the same width as the blank 1 through a machine which forms the sheet into consecutive fields, alternate fields 3 being flat and preceding and subsequent fields 2 and 4 being corrugated. Blanks 1 are cut from the sheet and supplied to a machine to bend the fields 2 and 4 as shown in Figure 2. When bending is complete the end edges 5 and 6 are in contact with each other. These edges can be joined in any manner whatsoever. In the present case the intention is that they shall be joined by welding or glueing. A finished unit is shown in Fig.3, the join being designated 7. It is also possible to refrain from joining the edges 5 and 6. In this case it is advisable for the edges 5 and 6 to be located opposite each other. They may either be edge to edge or spaced from each other.
