Abstract
A heat exchanger for fluids is disclosed having a support assembly for the coil bundle which comprises two vertically spaced-apart support members between which the coil bundle of the exchanger is positioned. The bundle comprises a plurality of vertically spaced tubes each having a number of convolutions which slope upwardly and proceed outwardly to form the bundle. A bridge member having spaced-apart scalloped portions is provided which separate the convolutions of each tube to permit air and water to circulate therebetween. The support members have means for varying the slope of the bridge members depending on the nature of the fluid entering the exchanger.
Claims8
A radial flow heat exchanger for fluids comprising:
- a. a plurality of tubes connected to an inlet header at vertically spaced points for receiving said fluid, each tube having a plurality of convolutions which slope in proceeding outwardly to the larger diameter convolutions thereof forming an annular assembly, and a vertically disposed outlet header connected to each tube at the outer periphery, said annular assembly having an open central area,
- b. means for drawing air over the outside of said tubes,
- c. means for dispensing a coolant liquid over the outside of said tubes,
- d. pan means beneath said annular assembly to receive said coolant liquid,
- e. means for supporting each of said tubes in spaced apart relationship, and
- f. means for varying the slope of said tubes depending on the nature of said fluid to be supplied to said exchanger.
In a heat exchanger of the type having a vertically disposed inlet header for receiving the fluid to be cooled, a plurality of tubes connected to said inlet header at vertically spaced points, each tube having a plurality of convolutions which slope in proceeding outwardly to the larger diameter convolutions forming an annular assembly, a vertically disposed outlet header connected to each of said tubes at the outer periphery of the annular assembly for guiding the cooled fluid from the outer ends of said tubes, said annular assembly having an open, unobstructed central area defined by the inner convolutions of said tubes, means for drawing air over all the circumferential portions of said tubes, means for dispensing a coolant liquid over the outside of said tubes, and pan means beneath said coils to collect said water, the improvement comprising:
- a. a plurality of vertically disposed, circumferentially spaced-apart outer coil support members adjacent said larger diameter convolutions,
- b. a plurality of vertically disposed, circumferentially spaced-apart inner coil support members adjacent said smaller diameter convolutions, each of said inner coil support members being in spaced apart radial alignment with an outer coil support member, and
- c. bridge means extending between said inner and outer coil support members for supporting each of said vertically spaced plurality of convolutions in said sloping manner, said bridge means having spaced-apart scalloped portions which separate said convolutions of each tube to permit said air and water to circulate therebetween.
