Abstract

Disclosed is a system for receiving condensate from a v-coil heat exchanger (v-coil), having: a receptor that has: a first channel having a first length defined between first opposing ends, the first channel configured to receive the v-coil, the first channel having a first bottom surface; a second channel disposed at an angle to the first channel and connecting with the first channel at a junction so that fluid flows downstream from the first channel into the second channel, the second channel having a second bottom surface that extends below the first bottom surface; and a heat shield connected to the first channel and extending below the first channel.

First claim

What is claimed is:

1. A system for receiving condensate from a v-coil microchannel heat exchanger (v-coil), comprising:
a receptor that is T-shaped and comprises:
a first channel having a first length defined between first opposing ends, the first channel configured to receive the v-coil, the first channel having a first bottom surface;
a second channel disposed at an angle to the first channel and connecting with the first channel at a junction so that fluid flows downstream from the first channel into the second channel, the second channel having a second bottom surface that extends below the first bottom surface, the second channel extends to opposite ends and includes a drain port that is spaced apart from the junction and disposed at one or both of the opposite ends;
a heat shield connected to the first channel and extending below the first channel, and
a v-coil fixedly supported by the receptor,
wherein:
the first channel has a cross section with a top portion that is arcuate and converges toward a bottom portion of the v-coil;
the heat shield is V-shaped and includes sidewalls extending from a bottom apex;
a bottom surface of the heat shield, defined by the bottom apex, is level with the second bottom surface of the second channel,
the bottom surface of the heat shield forms a rounded base; and
the heat shield connects with the first channel at top edges of opposing side walls of the first channel.

2. The system of claim 1 , wherein:
the heat shield has side walls that converge at the bottom surface of the heat shield so that an air gap is formed between the first channel and the heat shield.

3. The system of claim 1 , wherein the heat shield connects with the first channel at or below a bottom portion of the first channel.

4. The system of claim 3 , wherein the heat shield is fastened to the first channel at or below the bottom portion of the first channel.

5. The system of claim 4 , wherein the heat shield is fastened against an upstream end of the first channel.

6. The system of claim 5 , wherein the heat shield is fastened to the first channel with screws.

7. The system of claim 1 , wherein a bottom portion of each of the opposing side walls of the first channel is oriented at a mutually converging angle and the side walls of the heat shield are oriented at the same converging angle so that the bottom portion of the side walls of the first channel and the side walls of the heat shield are parallel.

8. The system of claim 7 , wherein a top portion of each of the opposing side walls of the first channel are mutually parallel and the heat shield and first channel are configured so that air gaps are provided between the top portion of each of the opposing side walls of the first channel and the heat shield.

9. The system of claim 8 , wherein the side walls of the heat shield are offset from the bottom portion of each of the opposing side walls of the first channel, thereby providing air gaps between the heat shield and the bottom portion of each of the opposing side walls of the first channel.

10. The system of claim 9 , wherein the heat shield has rounded top edges that extend toward one another to engage top edges of the opposing side walls of the first channel.

11. The system of claim 10 , wherein contact between the heat shield and the first channel is only along the top edges of the opposing side walls of the first channel, thereby providing continuous air gaps between the heat shield and the first channel around the opposing side walls of the first channel and the bottom surface of the first channel.

12. The system of claim 11 , wherein the heat shield connects with grooves formed in the top edges of the opposing side walls of the first channel.

13. The system of claim 12 , wherein a span of the grooves in the top edges of the opposing side walls of the first channel is from an upstream end of the first channel to a downstream and of the first channel and the heat shield connects with the grooves along the span of the grooves.

14. The system of claim 13 , wherein the heat shield is formed of a resilient material that biases the rounded top edges of the heat shield into the grooves of the first channel.
