Abstract
A plate floor heat exchanger has a plurality of conductive mutually parallel plates spaced apart by narrow gaps defined by spacer bands which can have a streamlined shape and each of which are traversed by a plurality of tubes extending perpendicular to the plates. The spaces between longitudinal edges of these bands define flow channels for a fluid in a heat exchange relationship with the fluid traversing the tubes.
Claims6
A plate floor heat exchanger comprising:
- at least two spaced-apart mutually parallel plates of thermally conductive material;
- a plurality of tubes extending generally perpendicularly through said plates for conducting a first fluid therethrough;
- and
- elongated flat spacer bands disposed between said plates and spacing the same apart whereby said plates directly abut opposite faces of said bands, each spacer band being transversed by a respective group of said tubes in a linear row whereby longitudinal edges of said bands define between them flow channels for a second fluid between said plates, the width of each band alternating along the length thereof between regions of greatest width and regions of smaller width, the region of greatest width being located in the region of a respective tube, the regions of smaller width being located in regions between the tubes of the respective group, said tubes, said bands and said plates being in heat conductive contact with one another, said bands being staggered such that a relative wide part of one of said bands is juxtaposed with a relatively narrow part of one another of said bands spaced from said one of said bands.
