Abstract

A heat exchanger is constituted by a plurality of interconnected heat exchange elements. Each element is a straight extruded tube (1) having cooling fins (2 and 2'). The fins (2 and 2') are provided, at their ends, with complementary interengageable means (3 and 7). Locking means (20) are provided for maintaining the engagement of said complementary means (3 and 7), thereby securing the elements together. In this way, a readily transportable, and easily assembled, cryogenic evaporator can be produced in any required size. <IMAGE>

Description

SPECIFICATION Heat exchanger This invention relates to a heat exchanger, and in particular to a low-pressure heat exchanger for a cryogenic evaporator.
A known type of cryogenic evaporator has heat exchange elements constituted by a plurality of straight finned tubes, the tubes being mounted on a support structure. Depending upon the type of arrangement of the tubes, through which a heat exchange fluid passes, the support structure may be a steel frame or a central column. Thanks to the support structure, the cooling fins of the tubes, which extend alongside one another, are spaced apart, rather than being in contact. The tubes of such a cryogenic evaporator are extruded in aluminium alloy for low-pressure purposes, and each tube is formed integrally with its cooling fins, which are arranged in a star-shaped congifuration.
An evaporator of this type is usually completely assembled at the factory. It is then packed, and transported in the assembled condition to the place of use. If this is a considerable distance away, this is disadvantageous because of high transport cost arising from the volume of the assembled unit.
Another disadvantage is that a crane is often required during both transportation and erection on site. Moreover, the need to provide an evaporator of this type with a support structure increases the cost of production.
The aim of the invention is to provide a heat exchanger which does not require a separate support structure, and which can be erected by a single worker without the aid of a crane.
The present invention provides a heat exchanger comprising a plurality of interconnected heat exchange elements, each of which is constituted by a straight, finned extruded tube, wherein adjacent fin ends of adjacent elements are provided with complementary interengageable means, and wherein locking means are provided for securing the elements to one another.
Two forms of heat exchanger, each of which is constructed in accordance with the invention, will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a cross-section through a heat exchange element of the first form of heat exchanger; Figure 2 is a perspective view of the first form of heat exchanger; Figure 3 is a plan view of the first form of heat exchanger; Figure 4 is an enlarged view of part of the first form of heat exchanger, and shows the connection between two of its elements; and Figure 5 is a diagrammatic plan view of the second form of heat exchanger.
Referring to the drawings, Figure 1 shows a heat exchange element having an extruded tube 1 provided with a plurality of generally radially outwardly extending fins 2, 2', 5, 5', 8 and 11. The fins 2 and 2' are diametrically-opposite, arcuate fins, and are formed with complementary interengageable means 3 and 7 respectively at the ends thereof. The interengageable means need not have the specific form shown, but could have any tongue-and-groove form. The two arcuate fins 2 and 2' together define a quarter-circle.
A pair of L-shaped short ribs 4 are formed on the convex side of the arcuate fin 2, the free ends of the ribs extending towards each other to form a boxsection open at one side.
The fins 5 and 5' are provided at the convex side of the two arcuate fins 2 and 2', the fins 5 and 5' defining an enclosed angle of 90 in the zone adjacent to the tube 1. At a certain distance from the tube 1, the fins 5 and 5' are angled in so that their end portions 6 extend parallel to each other. The fins 5 and 5' are also provided with complementary interengageable means 3 and 7 respectively at their ends, these means being of a similar shape to the corresponding means 3 and 7 of the arcuate fins 2 and 2'.
The fins 8 are provided at the concave side of the two arcuate fins 2 and 2'. The fins 8 have end portions 9 which are parallel to each other. The distance between the parallel end portions 6 of the fins 5 and 5' is so great that the parallel end portions 9 of the fins 8 of a similar heat exchange element can be accommodated between them when such elements are stacked for transport purposes. The ends 10 of the fin portions 9 are angled inwards so at to lie at 90 to the fin portions 8, so that, in the stacked condition, the ends 10 lie on the fin portions 5 and 5' of an adjacent element. The fin 11 is provided between the two fins 8, the fin 11 having a curved contact face 12 at its free end. In the stacked condition, this contact face 12 bears against the tube 1 of an adjacent element between the two fins 5 and 5' of that adjacent element.
In principle, any type of tongue-and-groove construction can be considered for providing the complementary interengageable means 3 and 7. In view of the length of the individual elements, however, structures which simply form a contact fit, one within the other, are preferred to those that have to be pushed one into another.
Figure 2 shows a heat exchanger made up of four elements such as that shown in Figure 1. The four elements are arranged with their concave fin formations 2 and 2' facing each other to form a cylinder.
The individual straight extruded tubes 1 are interconnected by suitably curve lengths of tube 13 and 14. A heat exchange medium flows thorugh the tubes 1,13 and 14 in such a manner that the inlet 15 and the outlet 16 are disposed diametrically opposite each other.
The heat exchanger is supported on four feet 17, each of which is formed from a flat bar. These flat bars are pushed into the box-sections 4, and are held fast by means of pressure plates 18. The feet 17 can be positioned at different levels within the boxsections 4 by the pressure plates 18. The individual heat exchange elements are held together by means of clips 20 (see Figure 4) which lock the interengageable means 3 and 7 of the fins 2 and 2' together.
For cryogenic purposes, the illustrated heat exchanger is used mainly as an evaporator. Atypical unit of the type shown in Figure 2 has a capacity of 100 Nm3/h when built to a height of approximately 5 metres. With this equipment, the ihitially liquid gas is warmed from approximately -200"C to a temperature of about 10"C below the ambient temperature.
Figure 3 is a plan view of such an evaporator unit.
For large installations, a plurality of such units are combined (see Figure 5), the individual units being connected together by the interengageable means 3 and 7 provided on their fins 5 and 5'. Here again, these connections are locked by means of clips 20.
It will be apparent that the arrangement described above could be modified in a number of ways, provided that the extruded straight tubes 1 are provided with cooling fins which can be used for interconnection, so that a heat exchanger can be provided which does not require a special support structure, which can be transported in a spacesaving manner, and which can be easily assembled on site.
