Abstract

A header for a heat exchanger orients the position of an inlet port at an angle offset from the position of the outlet port on the header body in order to simplify the plumbing of the header within a system. In one implementation of a header for a heat exchanger, the header forms a header cavity defined by an external wall and which is separated into an inlet chamber and an outlet chamber by a dividing wall. An inlet port is defined within the external wall and is in fluid communication with the inlet chamber. Similarly, an outlet port is defined within the external wall and is in fluid communication with the outlet chamber. The inlet port is oriented on the external wall at an offset angle with respect to a position of the outlet port.

First claim

What is claimed is:

1. A pool/spa water treatment system comprising
a pool filter including a pool filter inlet in fluid communication with a pool filter outlet;

the pool filter inlet and pool filter outlet are positioned at a first elevation and on opposite sides of the pool filter; and
a heat exchanger header for a heater including a header inlet in fluid communication with the pool filter outlet and a header outlet,
the header inlet and the pool filter outlet aligned within the same vertical plane and adapted to align with a piping connection to improve system efficiency, and
the header inlet at a second elevation, wherein the second elevation is vertically offset from the first elevation, and
the header outlet at a third elevation, wherein the third elevation is vertically offset from the first elevation and the second elevation, and the third elevation is vertically offset lower than the second elevation.

2. The pool/spa water treatment system of claim 1 , wherein
the heat exchanger header is defined by an external wall and separated into an inlet chamber and an outlet chamber by a dividing wall;
the header inlet is defined within the external wall in fluid communication with the inlet chamber; and
the header outlet is defined within the external wall in fluid communication with the outlet chamber; wherein
the header inlet is oriented on the external wall at an offset angle with respect to a position of the header outlet.

3. The pool/spa water treatment system of claim 1 , wherein the heat exchanger header further comprises
one or more heater outlet ports in fluid communication with the inlet chamber; and
one or more heater inlet ports in fluid communication with the outlet chamber.

4. The header for the heat exchanger of claim 3 , wherein the heater outlet ports are positioned in a common plane with the heater inlet ports.

5. The header for the heat exchanger of claim 4 , wherein the heater outlet ports and the heater inlet ports are positioned at a second offset angle with respect to a position of the header inlet and a third offset angle with respect to the position of the header outlet.

6. The pool/spa water treatment system of claim 1 , further comprising at least one of a chlorine generator, a pump or a valve.

7. The pool/spa water treatment system of claim 6 , wherein the valve is a diverter valve.

8. A pool/spa water treatment system, comprising:
a poor filter including a pool filter inlet and a pool filter outlet; and
a heat exchanger header for a heater including a header inlet and a header outlet, the header inlet in fluid communication with the pool filter outlet, wherein
the pool filter inlet and the pool filter outlet are aligned within a first vertical plane,
the pool filter inlet and the pool filter outlet are positioned at a first elevation,
the header inlet at a second elevation, wherein the second elevation is vertically offset from the first elevation, and
the header outlet at a third elevation, wherein the third elevation is vertically offset from the first elevation and the second elevation, and the third elevation is vertically offset lower than the second elevation.

9. The pool/spa water treatment system of claim 8 , wherein the header inlet is positioned at a second elevation, the header further includes a header outlet positioned at a third elevation, the header inlet aligned within the first vertical plane, and the header inlet is offset a select angle relative to the header outlet.

10. The pool/spa water treatment system of claim 9 , wherein the header outlet is positioned within a second vertical plane, the second vertical plane offset from the first vertical plane.

11. The pool/spa water treatment system of claim 9 , wherein the first elevation is different than the second elevation.

12. The pool/spa water treatment system of claim 9 , wherein
the heat exchanger header is defined by an external wall and separated into an inlet chamber and an outlet chamber by a dividing wall;
the header inlet is defined within the external wall in fluid communication with the inlet chamber; and
the header outlet is defined within the external wall in fluid communication with the outlet chamber; wherein
the header inlet is oriented on the external wall at an offset angle with respect to a position of the header outlet.

13. The pool/spa water treatment system of claim 12 , further comprising a chlorine generator including a chlorine generator inlet in fluid communication with the header outlet, and the chlorine generator inlet is positioned at the third elevation.

14. The pool/spa water treatment system of claim 13 , further comprising a pump including a pump inlet and a pump outlet, the pump inlet and pump outlet aligned within a third vertical plane.

15. The pool/spa water treatment system of claim 14 , wherein the third vertical plane is transverse to the first vertical plane.

16. The pool/spa water treatment system of claim 12 , further comprising a valve including a valve fluid inlet in fluid communication with a chlorine generator outlet, the valve fluid inlet positioned at a fourth elevation.

17. The pool/spa water treatment system of claim 16 , wherein the fourth elevation is the same as the third elevation.

18. A pool/spa water treatment system, comprising:
a pool filter including a pool filter inlet in fluid communication with a pool filter outlet; and
a header for a heat exchanger including a header inlet and a header outlet, the header inlet in fluid communication with the pool filter outlet,
wherein the pool filter inlet and pool filter outlet are positioned at a first elevation and aligned along a first axis,
the header outlet is positioned at a second elevation,
the header inlet is positioned along a second axis, the second axis vertically offset from and parallel to the first axis,
and the first elevation is vertically offset relative to the second elevation, and
the header inlet is positioned at a third elevation, wherein the third elevation is vertically offset from the first elevation and the second elevation, and the third elevation is vertically offset higher than the second elevation.

19. The pool/spa water treatment system of claim 18 , wherein the header inlet is oriented on an external cylindrical wall of the heat exchanger header at an offset angle with respect to a position of the header outlet.

20. The pool/spa water treatment system of claim 18 , further comprising a chlorine generator having a chlorine generator inlet and chlorine generator outlet positioned at a third elevation, the second elevation and third elevation substantially similar.
