Abstract

A heat exchanger system and method includes a securing frame, a heat transfer core having heat transfer panels removably secured to the securing frame, the heat transfer panels optionally including a plurality of segment modules coupled together, and one or more filter screens removably secured to the securing frame at one or both of an inlet end or an outlet end. The heat transfer core is disposed between the inlet end and the outlet end.

First claim

What is claimed is:

1 . A heat exchanger system, comprising:
a securing frame; a heat transfer core secured to the securing frame; and one or more filter screens secured to the securing frame at one or both of an inlet end or an outlet end, wherein the heat transfer core is disposed between the inlet end and the outlet end.

2 . The heat exchanger system of claim 1 , wherein the heat transfer core comprises heat transfer panels.

3 . The heat exchanger system of claim 2 , wherein the heat transfer panels are removably coupled to the securing frame.

4 . The heat exchanger system of claim 2 , wherein the heat transfer panels comprise fluid passages in fluid communication to form a fluid circuit that extends between a fluid inlet and a fluid outlet.

5 . The heat exchanger system of claim 2 , wherein the heat transfer panels comprise heat transfer fins separated by fluid channels.

6 . The heat exchanger system of claim 2 , wherein each of the heat transfer panels comprises a plurality of segment modules removably coupled together.

7 . The heat exchanger system of claim 2 , wherein the heat transfer panels are devoid of guard fins.

8 . The heat exchanger system of claim 1 , wherein the one or more filter screens are removably coupled to the securing frame.

9 . The heat exchanger system of claim 1 , wherein the one or more filter screens comprise a protective barrier within a protective opening.

10 . The heat exchanger system of claim 9 , wherein the protective barrier comprises rigid cross beams spaced apart by openings.

11 . The heat exchanger system of claim 10 , wherein the protective barrier further comprises a wire mesh screen extending between the rigid cross beams.

12 . The heat exchanger system of claim 10 , wherein the protective barrier further comprises columns that intersect the rigid cross beams.

13 . The heat exchanger system of claim 1 , wherein the one or more filter screens comprise an inlet filter screen at the inlet end.

14 . The heat exchanger system of claim 13 , wherein the one or more filter screens further comprise an outlet filter screen at the outlet end.

15 . The heat exchanger system of claim 1 , wherein the one or more filter screens are spaced apart from the heat transfer core.

16 . The heat exchanger system of claim 1 , wherein the heat exchanger system is in fluid communication with a RAM air cooling system of an aircraft.

17 . An aircraft comprising:
a RAM air cooling system; and a heat exchanger system in fluid communication with the RAM air cooling system, the heat exchanger system comprising:
a securing frame;
a heat transfer core secured to the securing frame, wherein the heat transfer core comprises heat transfer panels removably coupled to the securing frame, and wherein the heat transfer panels comprise heat transfer fins separated by fluid channels, and fluid passages in fluid communication to form a fluid circuit that extends between a fluid inlet and a fluid outlet; and
one or more filter screens removably secured to the securing frame at one or both of an inlet end or an outlet end, wherein the heat transfer core is disposed between the inlet end and the outlet end, and wherein the one or more filter screens comprises a protective barrier within a protective opening.

18 . The aircraft of claim 17 , wherein each of the heat transfer panels comprises a plurality of segment modules removably coupled together.

19 . The aircraft of claim 17 , wherein the one or more filter screens are spaced apart from the heat transfer core.

20 . A method for a heat exchanger system, the method comprising:
removably securing heat transfer panels of a heat transfer core to a securing frame; and removably securing one or more filter screens to the securing frame at one or both of an inlet end or an outlet end, wherein the heat transfer core is disposed between the inlet end and the outlet end.

21 . The method of claim 20 , wherein each of the heat transfer panels comprises a plurality of segment modules removably coupled together.
