claims- This invention relates to a detail tructurll changeinaradiatorcoreofthetypeshownin mmons and Ramsaur Patent No. 1,998,688. It has to do with the formation of the ins for the eifective transfer of heat from the fin surface to the particles of air which move through the core.
air stream it is important that the maximum number of particles in the air available be brought into fin wiping contact. The depth of a core a tortuous path and in some measure cause a greater number of air particles to wipe the radiating suflace than occurs with uninterrupted air cells having straight and smooth walls. Buch bailies necessarily obstruct and restrict free flow and reduce the amount of air whicha core can pass under given conditions.
It is an object of the present invention to provide an improved fin structure which not only works a maximum number of air particles but no expensive changes are required for its production, it is simpler in design and easier and cheaper to form.
In the preferred embodiment there is involved a serpentine separator strip to be located in the 45 space between adjacent tubes so that angularly related fins extend almost straight across from one tube to the other for rigidity in assembly 50 sections each of which lies in a plane parallel with the direction of air flow but out of line with the neighboring fin sections. Thus the niccessive sections of the fin are at various heights in the air stream wherefore each cuts into a different stratum or in other words a fresh portion of the ishowsinlet and outlet headers Ia and l at the top and bottom the As will be un core comprises a number of tubescona5 necting the headers i and l for the flow in thin streams of cooling liquid, the heat from which is transferred to the metal of the tubes and the mating plates l and I formed as discl beforementioned Emmons and Ramsaur Patent No. 1,998,663 with their opposite edge portions corrugated so that the plates are fitted together inspaced relation and sealed along both sides. Immediately adjacent the internested edges each plate is provided with a row of rounded embossrnents i which serve to center and locate the seating portions of the separator or fln strip.
- The serpentine separator strip provides a series of angularly related fins Joined .in the reversed bends I along opposi which alternately engage the walls water tubes along lines between adjoining bosses 8. To hold the parts in assembled relation and ailord a good thermal bond the seating portions of the separator strip and wall plates may be soldered or otherwise Joined. Each fln, therefore,
is common to the water tubes on opposite sides thereof for the dissipation of heat from both tubes."
lnthepresentcaseeachfinisprovidedatlongitudinally spaced intervals with transverse slits which extend across the fin between the apexel as I claim:
angularly related fins above and below the same 1. In a radiator, a set of water tubes connect- The fin is, therefore, divided into a longitudinal ing the upper and lower tanks; an intermediate succession of separate sections all integral with indirect cooling strip of zigzagformatiombetween both bends along opposite sides. These sections are numbered 8, 9, III, II, I! and I3 in Figure 4. end section 8 the sections 2. In a radiator core having spaced tubes, a separator strip between each tube and the next adjacent tube, each separator strip being of zigzag formation with succeeding runs spaced longitudinally cell and, therefore, any given air particle will alternate relation the material in each a x wipe but one fin section of the group. being continuous across the width of the strip The period of wiping contact will be predeon a straight line, said runs being common to cally, the fin sections in a given plane W111 be fins being arranged in groups, with the endmost wiped by the same air particles. However, inasfins of each group in a common plane and the much as the coplanar fin sections are spaced a intermediate fins in planes oflset to one another plane of the 4. A tube coplanar fin section.
From the above it will be number of air particles will evident that a great WILLARD O. EM.MONS.
