Abstract

A can-type heat exchanger may include a housing having a space therein, integrally formed with a mounting portion, and a first inlet and a first outlet; a partition wall integrally formed to the housing, separating the space and the inside of the mounting portion, and forming a bypass passageway inside of the housing; a heat radiating unit inserted into the space, provided with connecting lines alternately formed by stacking a plurality of plates; a cover cap mounted at opened one surface of the housing, and a second inlet and a second outlet for communicating a second connecting line of the connecting lines; and a valve unit mounted at the first inlet formed in the mounting portion and penetrating the partition wall in the mounting portion, selectively opening and closing the space or the bypass passageway separated by the partition wall using linear displacement.

First claim

What is claimed is:

1. A can-type heat exchanger comprising:
a housing of which a first surface is opened and a second surface is closed and having a space therein, integrally formed with a mounting portion provided in a lateral side and communicated with the space, and a first inlet and a first outlet provided in the mounting portion and the lateral side thereof;
a partition wall integrally formed to the housing, separating the space and an inside of the mounting portion, connected to the first inlet and the first outlet, and forming a bypass passageway inside of the housing;
a heat radiating unit inserted into the space, provided with connecting lines alternately formed by stacking a plurality of plates, one of the connecting lines communicating with the space, and where operating fluids are heat-exchanged with each other while passing through the respective connecting lines;
a cover cap mounted at the opened first surface of the housing so that the heat radiating unit integrally mounted on one surface thereof to the space, and a second inlet and a second outlet for communicating with the other connecting line of the connecting lines, are formed at the first surface; and
a valve unit that is mounted at the first inlet formed in the mounting portion and penetrating the partition wall in the mounting portion, selectively opening and closing the space or the bypass passageway separated by the partition wall using linear displacement which is generated when expansion and contraction occur according to a temperature of the operating fluids flowing from the first inlet, and adjusting flow of the operating fluids.

2. The can-type heat exchanger of claim 1 , wherein
a coupling portion is integrally formed with an exterior circumference of the cover cap to be bent toward the housing.

3. The can-type heat exchanger of claim 2 , wherein
the coupling portion is clinching-coupled to the housing in a state that an interior circumference thereof is surrounded by an exterior circumference of the housing.

4. The can-type heat exchanger of claim 1 , wherein
a seal ring is disposed between the housing and the cover cap.

5. The can-type heat exchanger of claim 1 , wherein
the first inlet and the first outlet are respectively formed at a position intersecting the second inlet and the second outlet.

6. The can-type heat exchanger of claim 1 , wherein
the plates are formed with a disk shape corresponding to the housing, and a side corresponding to the partition wall is formed with a linear shape.

7. The can-type heat exchanger of claim 1 , wherein
first and second connecting holes are formed to the plates corresponding to the second inlet and the second outlet.

8. The can-type heat exchanger of claim 7 , wherein the heat radiating unit further comprises:
a first fixing plate being mounted to a first surface of the heat radiating unit which is fixed to the cover cap and forming first and second penetration holes which are formed to correspond with the first and second connecting holes; and
a second fixing plate mounted with a second surface of the heat radiating unit which is inserted into the space.

9. The can-type heat exchanger of claim 1 , wherein the plates comprise:
a plurality of protrusions protruded from the plates to be disposed apart from each other by a set interval; and
a distributing protrusion formed from a center of the plates to an exterior circumference of the plates to be disposed between the first inlet and the first outlet.

10. The can-type heat exchanger of claim 9 , wherein
the protrusions are formed with a hemisphere shape and are protruded from the plates in a same direction as the distributing protrusion.

11. The can-type heat exchanger of claim 1 , wherein the valve unit comprises:
an outer case inserted into the first inlet from outside of the mounting portion, the outer case comprising a fixing portion of which a mounting groove is integrally formed to an interior surface of the first inlet thereof, and is mounted to an external side of the mounting portion at an opposite side of the first inlet, an insert portion integrally formed to the fixing portion, at least one first opening hole formed along a length direction corresponding to the space separated by the partition wall, and at least one bypass hole formed corresponding to the bypass passageway;
a fixing rod which is inserted into the outer case and of which a first end is fixedly mounted to the mounting groove of the fixing portion;
a deformable member inserted to the fixing rod, and moved on the fixing rod by expansion or contraction according to a change of temperature of the operating fluids;
an inner case of which at least one second opening hole is formed along a length direction thereof corresponding to the at least one first opening hole of the outer case, and which is slidably inserted into the outer case;
a flange member which is fixed to a first end of the inner case therein, and fixed to a lower portion of the deformable member;
a stopper fixed to the insert portion from an opposite side of the fixing portion of the outer case; and
an elastic member disposed between the deformable member and the stopper, that is compressed when the deformable member is expanded, and that supplies elastic force to the deformable member.

12. The can-type heat exchanger of claim 11 , wherein
the fixing portion of the outer case is fixed to an end cap, which is mounted to the mounting portion on an external surface of the fixing portion.

13. The can-type heat exchanger of claim 11 , wherein
the outer case is formed with a cylinder shape of which the first end is opened.

14. The can-type heat exchanger of claim 11 , wherein
the at least one bypass hole and the at least one first opening hole are formed apart from each other along the length direction of the outer case at a predetermined angle.

15. The can-type heat exchanger of claim 11 , wherein
the at least one first opening hole is formed apart from the bypass hole at the lower portion of the outer case along the length direction of the outer case toward the fixing portion.

16. The can-type heat exchanger of claim 11 , wherein
the inner case is formed with a cylinder shape of which both ends are opened.

17. The can-type heat exchanger of claim 11 , wherein
the at least one second opening hole is formed to be misaligned along the length direction of the inner case at a predetermined angle from each other.

18. The can-type heat exchanger of claim 11 , wherein
the inner case is moved toward the first inlet by expansion of the deformable member in the outer case so that the at least one second opening hole is positioned at the at least one first opening hole to open the at least one first opening hole and close the bypass hole by the inner case.

19. The can-type heat exchanger of claim 11 , wherein
