Abstract

A heat exchanger includes a pipe having an opening formed therein, and an insert positioned within the pipe. The heat exchanger also includes a cap member for sealing the opening, and a support member for resiliently supporting the insert. Specifically, the support member is positioned between the insert and the cap member.

Claims (33)

1. A heat exchanger comprising:

a pipe having at least one opening formed therein;

an insert comprising a case and a strainer portion positioned within the pipe;

at least one cap member for sealing the at least one opening;

a support member for resiliently supporting and positioned adjacent to the strainer portion of the insert, which is positioned between the strainer portion of the insert and the at least one cap member; and

a plate positioned within the pipe, wherein the plate comprises an insert hole formed therethrough;

wherein the insert comprises a flange having an outer diameter which is greater than a diameter of the insert hole.

2. The heat exchanger of claim 1 , wherein the pipe comprises a header pipe, and the at least one opening is formed through at least one end of the header pipe.

3. The heat exchanger of claim 2 , wherein the at least one opening comprises:

a first opening formed through a first end of the header pipe; and

a second opening formed through a second end of the header pipe, wherein the at least one cap member comprises:

a first cap member for sealing the first opening; and

a second cap member for sealing the second opening.

4. The heat exchanger of claim 2 , wherein the at least one opening is formed through a first end of the header pipe, and a second end of the header pipe is tapered, such that an internal diameter of the second end of the header pipe is zero or approaches zero.

5. The heat exchanger of claim 1 , wherein the support member urges the insert to move in a predetermined direction, such that the flange engages the plate.

6. The heat exchanger of claim 1 , wherein the support member is fixed to the at least one cap member.

7. The heat exchanger of claim 1 , wherein the support member comprises an elastic protrusion.

8. The heat exchanger of claim 1 , wherein the support member comprises a bellow.

9. The heat exchanger of claim 1 , wherein the support member comprises an O-ring.

10. The heat exchanger of claim 1 , wherein the insert comprises a desiccant unit.

11. The heat exchanger of claim 10 , wherein the desiccant unit comprises a desiccant.

12. The heat exchanger of claim 1 , wherein the at least one cap member comprises:

a cylindrical member fixed to the pipe, wherein the cylindrical member comprises an opening formed therein; and

a cap positioned within the opening of the cylindrical member.

13. The heat exchanger of claim 1 , wherein the pipe comprises storage tank containing the strainer portion of the insert.

14. A heat exchanger comprising:

a pipe having at least one opening formed therein;

an insert comprising a case and a strainer portion positioned within the pipe;

at least one cap member for sealing the at least one opening;

a support member for resiliently supporting the insert, wherein the strainer portion is positioned adjacent to the at least one cap member; and

a plate positioned within the pipe, wherein the plate comprises an insert hole formed therethrough;

wherein the insert comprises a flange having an outer diameter which is greater than a diameter of the insert hole.

15. The heat exchanger of claim 14 , wherein the support member is fixed to the insert.
