PLATE TUBE SPACER STRUCTURE Abstract of the Disclosure A plate tube spacer structure operable for concomitantly ef- fecting both the spacing and the supporting of the individual tubes of a tube bundle, the latter commonly constituting one of the components of a conventionally constructed heat exchanger. The subject plate tube spacer structure includes a plurality of elongated plates that are suit- ably disposed in stacked, spaced relation so as to allow for a layer of tubes to be interposed between each pair of adjacent plates. The plates each have a multiplicity of tube engaging means formed along each longi- tudinally extending side edge thereof. The multiplicity of tube engag- ing means are suitably disposed so as to effectively provide each plate with two parallel rows thereof. The arrangement of the rows of tube engaging means of each plate is such that the multiplicity of tube en- gaging means of one row thereof are aligned with, but face in a direc- tion opposite to that of the multiplicity of tube engaging means of the other row thereof. All of the multiplicity of tube engaging means of a given plate project outwardly in a common direction away from the plane of the plate, and are each suitably configured so that a tube may be tangentially engaged therewith in supported relation thereto. Also, the multiplicity of tube engaging means are each further provided with means operable for discouraging the buildup at the interface between a tube and the tube engaging means of deposits that could have a detri- mental effect on the tube. To provide the subject plate tube spacer structure with added strength, preferably at least some of the multi- plicity of tube engaging means of each plate are suitably secured to a corresponding number of tube engaging means of an adjacent plate.
