' In Sweden March 28, 1935 4 Claims. (Cl. 257-245) This invention relates to improvements in heat exchange apparatus, and it is an object of the tain. an apparatus being equally resistant to stresses and shocks as hitherto known apparatus of the kind referred to.
Another object of my invention is to provide apparatus of the kind referred to having an improved heat exchange efficiency.
Still another object of my invention is to decrease the weight and size of, such apparatus and nevertheless maintain their full capacity.
. Some embodiments of the invention are shown in the annexed drawings.
Fig. 1 is a sectional viewtaken on the line I--I of Fig. 2;
Fig. 2 is a sectional view taken on the line IIII of Fig. 1;
Fig. 3 is a view similar to Fig. 2 but showing another embodiment of the invention; and
Fig. 4 is a view similar to Fig. 2 but showing still another embodiment of the invention.
Referring now to the drawings, the apparatus comprises two parallel channels 3 and 4 for heat exchanging fluids. The channels are formed by plates bent to form convolute heat transmission walls I and 2. The channel 3 hasanouter inlet connection 5 and an inner outlet connection 5 and the channel 4 has an inner inlet connection I and an outer outlet connection 8. Hot liquid may, for instance, be supplied to the channel 4 through the inlet connection I and liquid to be heated may be supplied to the channel 3 through the inlet connection 5.
Fig. 2 shows exaggeratedly the thickness of both the walls I and 2 decreasing continuously then the saving of material will considerably reduce the entire costs of manufacture.
In apparatus operating at relatively small fluid pressures walls of uniform strength throughout would have very little thickness at the innermost convolutions and this would cause diificulties in manufacture. In such case it might be 5 suitable to use walls having a certain minimum thickness atthe inner convolutions as shown in Fig. 3. Thus it is assumed that the walls have a uniform thickness from their inner ends to a section at 9. 10
Instead of continuously varying the thickness of the convolute walls said thickness may vary stepwise as shown in Fig. 4. In such case each section may have a uniform thickness or a continuously varying thickness, and the sections may 15 be secured to one another at 50, or they may be integrally formed with one another.
Also in case there are used convolute walls having a continuously varying thickness said walls may be formed by sections secured to oneanother. 20 Possibly, one of the channel walls might be developed with varying thickness and the other wall or, walls may have a uniform thickness throughout as in hitherto used apparatus of the kind referred to.
I claim:-
1. A'heat exchange apparatus having convolute heat transmission walls forming channels for heat exchanging fluids, the thickness of said walls decreasing in a direction towards the cen- 30 tre of the apparatus. s
2. A heat exchange apparatus having convolute heat transmission walls forming channels for heat exchanging fluids, the thickness of said walls decreasing continuously in a direction to- 35 wards the centre of the apparatus.
3. A heat exchange apparatus having convolute heat transmission walls forming channels for heat exchanging fluids, the thickness of said walls decreasing stepwise in a direction towards the-centre of the apparatus.
4. A heat exchange apparatus having convolute heat transmission walls forming channels for heat exchanging fluids, the thickness of said walls decreasing in a direction towards the censaid walls having a uniform thickness.
