5 Claims.

The invention relates to improvements in heat transfer devices, commonly called radiators and more particularly the type used for cooling large internal combustion engines, wherein the ra- 5 diator is mounted on the engine supporting'frame,

or for use on rail cars, busses, trucks and the like. In either event the radiator is subjected to considerable vibration.

The usual vibration in radiators of this type is serious, in that the tubes are made of thin copper and therefore are fragile and sensitive to vibration which sooner or later results in leaky joints where the tube ends are attached to the header plates or fractures develop in the tubes near their connection" to the header plate.

In large radiators there is considerable weight in the core and the core is of considerable length. The center portion of the core oscillates sidewise. This oscillation is frequently quite noticeable and serious. There is also serious vibration at the top of the radiator when the housing is not rigid enough to prevent it.

The tubes do not greatly resist this side motion because they are usually flattened and positioned with the long section in a transverse direction to the direction of vibration.

The object of my invention is to provide simple and inexpensive means whereby the core is held against distortion or a sidewise bending movement. I accomplish these objects by means of a novel transverse anchor whereby the core about midway the headers, is secured to the side housing posts.

The preferred embodiment of my invention is illustrated in the accompanying drawing in which:

Figure 1 is a rear plan view of a radiator equipped with one form of my invention, a portion of the housing being cut away to clearly illustrate the manner of removably and adjustably securing the anchoring means to the housing.

Figure 2 is a transverse plan side view in elevation of the radiator shown in Figure 1 a portion of the housing member being cut away to clearly disclose the position of my improved anchoring device.

Figure 3 is an enlarged fractional section taken on line 3 of Figure 1.

As thus illustrated in Figures 1 to 3 inclusive, HI designates the upper header plate of the radiator core and I I designates the lower header plate. A plurality of vertical tubes l2 are suitably positioned in parallel relation and the ends bonded or otherwise made fast into corresponding openings in the plates l and II.

The upper header cap !3 is made fast to upper header plate i E? by means of a gasket and suitable bolts or otherwise attached. In the figures I illustrate my preferred form of construction wherein the header or tube plate i0 is very thin and is held to the flange of header 13 by means of the ends of housing members 30 and suitable bolts therebetween and the lower header cap 14 is similarly made fast to the lower tube plate I i. In the design shown housing members 36 form a protection for the core sides and have sufficient rigidity to answer as an anchor for the upper header and the core center as will hereinafter appear. Header cap 53 is supplied with the usual filler cap nipple I and a coolant circulating connection opening 16. The lower cap H2 is provided with coolant outlet openings 11. Thus when the proper connections are made, the coolant may pass into the cap 13, down through tubes 12, into cap i l and out through opening 11.

In order to increase the radiating capacity of the device, closely spaced fins l8 are provided.

These fins are provided with flanged openings (not shown) through which the tubes extend and are bonded in the usual manner thereto.

Thus it will be seen that I have shown a conventional radiator the tubes of which are preferably flattened in cross section.

If the core is supported from the lower header only, the top header, unless suitably held, may oscillate sidewise to a considerable extent and cause loose joints or fractured tubes, and when the upper header is held sufliciently rigid by the housing to prevent side movement, as illustrated in Figures 1 and 2, the core itself at its center, may be caused to vibrate sidewise and cause trouble at either end of the tubes. I provide novel means therefore, to prevent all side movement or vibration in the following manner:

Wires 3| are positioned between certain fins, preferably two in front and two in rear of the tubes E2, the ends passing through openings in end plates 32 which are laid on the ends of the fins and the ends of the wires bent over and made fast by bonding, after which the wires are also bonded to adjacent fins for their entire length. Thus this assembly will be firmly held to adjacent fins. The end plates 32 are provided with bolts 3333 which protrude through openings in the side walls of the housing as indicated. After this assembly is completed acorn nuts 34-34 are placed on the bolts 33 and tightened. Thus the core is anchored and held from vibrating by the relatively rigid and strong housing.

Wires 3| may be positioned on one side only of the cores and any number or combination of numbers may be used.

In radiators as shown the housing is, as already stated, rigid enough to hold the upper header from vibrating or oscillating sidewise. In the design shown the principal desideratum is therefore, to provide a housing sufi'iciently rigid to prevent side motion of the upper header relative to the lower header, and then bind the center portion of the core to the housing structure in a manner which will effectively hold the center portion of the core from side oscillation.

Thus it will be seen that I have provided novel ineans for anchoring the core to thereby prevent harmful distortion and vibrations.

Having thus shown and described my invention what I claim is:

1, A radiator, comprising two headers, a plurality of tubes in parallel relation having suitable end connectionsto said headers, a multiplicity of fins through which said tubes extend and are bonded thereto, a housing for said radiator, one or more transverse wires bonded to adjacent fins, and means whereby the ends of said wires are detachably anchored to the side walls of said housing.

2. A radiator, comprising two headers, a number of tubes in parallel relation having suitable end connections to said headers, a multiplicity of closely spaced fins through which said tubes extend and are bonded thereto, cross wires positioned between certain fins, bonded thereto and positioned on opposite sides of said tubes, end plates to which the ends of said wires are attaohed, a housing for said radiator and detachable means whereby said end plates are anchored to said housing.

3. A radiator, comprising two headers, a plurality of tubes in parallel relation having suitable connections to said headers, a multiplicity of fins through which said tubes extend, a housing for said radiator, one or more transverse wires midway said headers and positioned between fin edges and bonded thereto, means whereby the ends of said wires are detachably anchored to the side walls of said housing.

' 4. A radiator, comprising two headers, a plurality of tubes in parallel relation having suitable end connections to said headers, a multiplicity of closely spaced fins through which said tubes extend, two or more cross wires between opposite edges of certain fins bonded thereto and positioned midway said headers, end plates to which the ends of said cross wires are attached, a housing for said radiator having means wher by said end plates are detachably anchored thereto.

5. A radiator, comprising two headers, a plurality of tubes in parallel relation having suitable end connections. to said headers, a multiplicity of closely spaced fins through which said tubes extend, transverse Wires contacting certain fin edges and bonded thereto, end plates to which the ends of said wires are attached, side FRED M.
