Abstract
Dans un échangeur thermique à plaques constitué par un cadre dans lequel des lames plates et ondulées sont empilées, les lames étant alternativement plates et ondulées, l'utilisation d'une unité constituée par une lame plate (3) et par une lame ondulée (2 et 4), produites toutes les deux à partir d'une seule pièce brute, permet de simplifier l'empilage, et même le scellage.In a plate heat exchanger constituted by a frame in which flat and wavy blades are stacked, the blades being alternately flat and wavy, the use of a unit constituted by a flat blade (3) and by a wavy blade (2 and 4), both produced from a single blank, simplifies stacking, and even sealing.
Description
Foil arrangement
The present invention relates to a foil arrangement in a plate heat- exchanger. Such 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. During assembly of such plate heat-exchangers 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.
According to an alternative the middle field may constitute the corrugated part and the end fields the flat parts. In this alternatively 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.
The present invention will be further described with reference to the accompanying two sheets of drawings, in which
Figure 1 shows a blank for manufacture of a unit for a plate heat- exchanger,
Figure 2 shows the blank being folded and
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. From Fig.3 it is clear that when a plate heat-exchanger is to be assembled, only the unit shown in the latter figure is required, that is to say, only one product which is placed in a certain direction, the next being turned 90 in relation thereto, and so on. Each unit is automatically sealed at the edges parallel to the direction of flow.
Claims
1. Foil arrangement in plate heat-exchangers in which the foils are alternately flat and corrugated and in which corrugated foils are directed alternately in one direction and in a direction 90 thereto, characterised in that a flat foil (3) consisting of one or two parts and a corrugated foil (2 and 4) consisting of one or two parts, form a coherent unit.
2. Foil arrangement according to claim 1, characterised in that the flat foil (3) and corrugated foil (2 and 4) of the unit are produced from a single blank (2-4).
3. Foil arrangement according to claim 2, characterised in that the blank consists of a flat intermediate part (3) and two corrugated parts (2 and 4) located one on each side of the intermediate part (3) and designed to be folded, the free ends (5 and 6) to be joined by means of welding, glueing, riveting or the like.
4. Foil arrangement according to claim 3 , characterised in that the intermediate part is corrugated and the parts on each side thereof are flat.
5. Foil arrangement according to claim 3 or 4, characterised in that the gap between the opposite edges (5 and 6) of the free ends, when not joined, varies from zero upwards.
