Abstract

An insert is configured to be inserted into a heat exchanger having a plurality of tubes. The insert includes a base and a multiple blades. The blades are extended from the base. At least one of the blades has a spring portion. The spring portion is resiliently deformable and configured to be resiliently inserted between two of the tubes.

First claim

What is claimed is:

1. An insert for a heat exchanger having a plurality of tubes, the insert comprising:
a base; and
a plurality of blades extending from the base, wherein
at least one of the blades has a spring portion, which is resiliently deformable,
the spring portion includes two arms each of which protrudes away from each other to form an aperture therebetween,
the tubes include a first front tube, a second front tube, a first rear tube, and a second rear tube,
the first front tube and the second front tube define a first space therebetween,
the first front tube, the second front tube, the first rear tube, and the second rear tube define a second space therebetween,
the two arms define an original form with a width that is greater than the first space,
the two arms are configured to (i) allow the spring portion to be inserted into the first space by resiliently being bent inward and (ii) engage with the first front tube, the second front tube, the first rear tube, and the second rear tube in the second space by resiliently being bent back into the original form, wherein
the insert further includes a film formed of an elastic material in the aperture,
the film screens the aperture, and
the film is configured to be resiliently deformed when the spring portion is inserted into the first space.

2. The insert according to claim 1 , wherein
the base and the blades are integrally formed in a comb shape, and
the blades extend from the base perpendicularly to the base.

3. The insert according to claim 1 , wherein
the two arms include C-shaped portions, respectively, and
the C-shaped portions project outward.

4. The insert according to claim 3 , wherein the two arms are symmetrical with respect to an axis of the at least one of the blades.

5. The insert according to claim 3 , wherein
the at least one of the blades further includes a tip end and a root end,
the root end extends from the base,
the C-shaped portions extend from the root end, and
the tip end extends from the spring portion.

6. The insert according to claim 5 , wherein the C-shaped portions project outward relative to the root end and the tip end.

7. The insert according to claim 6 , wherein
the aperture further includes a first slit,
the arms further include first linear portions, respectively,
the first linear portions are located between the root end and the C-shaped portions, and
the first linear portions form the first slit therebetween.

8. The insert according to claim 7 , wherein
the aperture further includes a second slit,
the arms further include second linear portions, respectively,
the second linear portions are located between the C-shaped portions and the tip end, and
the second linear portions form the second slit therebetween.

9. The insert according to claim 8 , wherein
the aperture further includes a center hole,
the C-shaped portions form the center hole therebetween, and
the first slit, the center hole, and the second slit are arranged in this order to form a single hollow space.

10. The insert according to claim 9 , wherein
each of the C-shaped portions includes a first bent portion, a center portion, and a second bent portion, which are connected in this order, and
the center portion is located outside the first linear portion and the second linear portion.

11. The insert according to claim 1 , wherein the film includes a center film in a dome shape.

12. The insert according to claim 1 , wherein the base has an elastic base configured to be elastically in contact with the tubes.

13. The insert according to claim 1 , wherein the base has a plurality of protrusions projected from the base and located between two of the blades, which are adjacent to each other.

14. An insert for a heat exchanger having a plurality of tubes, the insert comprising:
a base; and
a plurality of blades extending from the base, wherein
at least one of the blades has a spring portion that is resiliently deformable,
the spring portion includes two arms each of which protrudes away from each other to form an aperture therebetween,
the tubes include a first front tube, a second front tube, a first rear tube, and a second rear tube,
the first front tube and the second front tube define a first space therebetween,
the first front tube, the second front tube, the first rear tube, and the second rear tube define a second space therebetween,
the two arms define an original form with a width that is greater than the first space,
the two arms are configured to (i) allow the spring portion to be inserted into the first space by resiliently being bent inward and (ii) engage with the first front tube, the second front tube, the first rear tube, and the second rear tube in the second space by resiliently being bent back into the original form, wherein
the insert further includes:
an elastic base formed of an elastic material on the base and configured to be elastically in contact with the tubes; and
at least two films each formed of the elastic material to extend from the base and to screen the aperture and configured to be resiliently deformed when the spring portion is deformed inward, wherein

the elastic base bridges the at least two films.
