Abstract

A heat exchange assembly is disclosed. In some embodiments, the heat exchange assembly includes a plurality of profiles arranged in an parallel array, each profile including a first distal portion, a central portion and a second distal portion, with a length and a width of the central portion defining a plane, the first distal portion having a curvature departing from this plane in a first direction, and the second distal portion having a curvature departing from this plane in a second direction that is opposite the first direction. An amount of piping is thermally coupled with and disposed along the length the central portion of each profile. A bracketing system statically anchors the profiles to a surface. Fluid is circulated within the piping to facilitate heat exchange between the assembly and the surrounding environment.

Claims

1. A heat exchange assembly, comprising:

a plurality of profiles arranged in an parallel array, each profile including;

a first distal portion, a central portion and a second distal portion,

wherein a length and a width of said central portion define a plane,

said first distal portion having a curvature departing from said plane in a first direction, said second distal portion having a curvature departing from said plane in a second direction that is opposite said first direction;

a spacing positioned between adjacent profiles and extending from a first side of the heat exchange assembly to a second side of the heat exchange assembly, said spacing having a width, wherein said width is greater than or equal to about 85 mm at least at said first side and said second side;

an amount of piping that is thermally coupled with said profiles, wherein with respect to each of said profiles a portion of said piping is disposed along said length of said central portion of said profile and is parallel to said length of said central portion of said profile;

a bracketing system configured to anchor said profiles and said piping to a surface;

said piping configured to circulate fluid having a temperature differential with respect to an environment in which the heat exchange assembly is disposed, whereby thermal energy is transferred between said piping and said profiles by conduction and thermal energy is transferred radiantly and convectively between said profiles and said environment.

2. The heat exchange assembly of claim 1 wherein said curvature of said second distal portion is a mirror image of said curvature of said first distal portion.

3. The heat exchange assembly of claim 2, wherein each profile has a channel protruding from said central portion of said profile and having disposed therein a portion of said piping.

4. The heat exchange assembly of claim 3, wherein said channels envelop and are thermally coupled with greater than 50 percent of an outer surface area of said portion of said piping.

5. The heat exchange assembly of claim 4 wherein said profiles are constructed from one of aluminum and an aluminum alloy, and said pipe is a precision drawn copper tube.

6. The heat exchange assembly of claim 1 wherein at least one of said profiles has a plurality of slots.

7. The heat exchanger of claim 6 wherein said slots extend in radial fashion from said central portion and are located wholly within one of said first distal portion and said second distal portion.

8. The heat exchanger of claim 3, further comprising:

a dew point monitor configured to determine a dew point temperature.
