Abstract

An impinging-type temperature uniformity device includes an outer case portion; and a temperature uniformizer provided in the outer case portion, spaced apart inwardly from an inner surface of the outer case portion and connected to the outer case portion, wherein the temperature uniformizer includes: a head portion provided in the outer case portion; and a body portion spaced apart inwardly from the inner surface of the outer case portion and including at least one through-hole.

First claim

What is claimed is:

1 . An impinging-type temperature uniformity device comprising:
an outer case portion; and a temperature uniformizer provided in the outer case portion, spaced apart inwardly from an inner surface of the outer case portion and connected to the outer case portion, wherein the temperature uniformizer comprises:
a head portion provided in the outer case portion; and
a body portion spaced apart inwardly from the inner surface of the outer case portion and comprising at least one through-hole.

2 . The impinging-type temperature uniformity device of claim 1 , wherein the head portion has a curved shape.

3 . The impinging-type temperature uniformity device of claim 1 , wherein the at least one through-hole comprises a plurality of through-holes, and
wherein a first through-hole and a second through-hole of the plurality of through-holes are symmetric to each other with respect to a center of the body portion.

4 . The impinging-type temperature uniformity device of claim 1 , wherein the temperature uniformizer further comprises a connecting portion connecting the body portion to the outer case portion.

5 . The impinging-type temperature uniformity device of claim 1 , wherein the head portion is provided at a first end of the temperature uniformizer along a longitudinal direction of the impinging-type temperature uniformity device, and
wherein the connecting portion is provided at a second end opposite to the first end of the temperature uniformizer along the longitudinal direction of the impinging-type temperature uniformity device.

6 . The impinging-type temperature uniformity device of claim 1 , wherein the head portion is provided at an upstream side along a flow direction of a gas passing through an inside of the outer case portion.

7 . The impinging-type temperature uniformity device of claim 1 , wherein a total area of the at least one through-hole is less than or equal to 30% of an area of a cross-section of the outer case portion and greater than or equal to 10% of the area of the cross-section of the outer case portion, the area of the cross-section of the outer case portion being taken in a direction perpendicular to a longitudinal direction of the impinging-type temperature uniformity device.

8 . The impinging-type temperature uniformity device of claim 1 , wherein a size of a cross-section of the body portion taken in a direction perpendicular to a longitudinal direction is greater than or equal to 10% and less than or equal to 30% of a cross-sectional area of the outer case portion taken in the direction perpendicular to the longitudinal direction.

9 . The impinging-type temperature uniformity device of claim 1 , wherein the body portion comprises a connecting body portion connected to the outer case portion.

10 . The impinging-type temperature uniformity device of claim 9 , wherein the connecting body portion is bent with respect to the body portion.

11 . The impinging-type temperature uniformity device of claim 9 , wherein the at least one through-hole is provided in a portion of the body portion excluding the connecting body portion.

12 . The impinging-type temperature uniformity device of claim 1 , wherein the at least one through-hole comprises a plurality of through-holes, and
wherein a predetermined angle is formed between adjacent through-holes from among the plurality of through-holes with respect to a center of a cross-section of the body portion taken in a direction perpendicular to a longitudinal direction of the body portion.

13 . The impinging-type temperature uniformity device of claim 12 , wherein the predetermined angle formed between the adjacent through-holes from among the plurality of through-holes with respect to the center of the cross-section of the body portion is greater than or equal to 6°.

14 . The impinging-type temperature uniformity device of claim 1 , further comprising a speed uniformizer provided on the outer case portion.

15 . The impinging-type temperature uniformity device of claim 14 , wherein the speed uniformizer is provided on a downstream side from the temperature uniformizer in a gas flow direction.

16 . The impinging-type temperature uniformity device of claim 1 , wherein the body portion of temperature uniformizer is integrally formed with the head portion of temperature uniformizer.

17 . The impinging-type temperature uniformity device of claim 1 , wherein the temperature uniformizer further comprises a diverging portion comprising:
a first end connected the body portion; and a second end opposite to the first end connected to the outer case portion.

18 . The impinging-type temperature uniformity device of claim 17 , wherein a cross-sectional area of the temperature uniformizer at the first end is smaller than a cross-sectional area of the temperature uniformizer at the second end.

19 . The impinging-type temperature uniformity device of claim 17 , wherein the at least one through-hole is provided at an upstream side of the diverging portion.

20 . The impinging-type temperature uniformity device of claim 19 , wherein the at least one through-hole comprises a plurality of through-holes.
