Abstract

Provided is a heat exchanger including a core portion configured to include an inlet header tank and an outlet header tank having a space, in which cooling water is stored and flows, formed therein and formed in a height direction, a plurality of tubes having both ends connected to the header tanks to form a cooling water channel, and fins interposed between the tubes, in which a core portion of the heater exchanger is formed to block only a part of a bypass area of a part where inlet/outlet header tanks are positioned to reduce a pressure loss of air which is a cooled fluid while minimizing a reduction in heat radiation performance of the heat exchanger and structural rigidity of the core portion is increased by a reinforcing structure formed at an outer side of the core portion to improve durability.

First claim

What is claimed is:

1. A heat exchanger, comprising:
a core portion configured to include an inlet header tank and an outlet header tank having a space, in which cooling water is stored and flows, formed therein and formed in a height direction, a plurality of tubes having both ends connected to the header tanks to form a cooling water channel, and fins interposed between the tubes, wherein the core portion has a width direction, a height direction and a length direction and has a side in the width direction, at least two sides in the length direction and two sides in the height direction;
a side reinforcing plate having ends at the width direction and disposed on at least one of both sides of the length direction side surfaces of the core portion and joined to the tubes, and wherein the side reinforcing plate is formed along the height direction and along the width direction; and
a pair of blocking plates extend in from the side reinforcing plate in the length direction to block an air inflow side of the core portion corresponding to a bypass area where the header tanks are formed,
wherein the pair of blocking plates are formed to block only a portion of an area where the header tanks are formed in the length direction,
wherein the bypass area is an area corresponding to a length from one end in the length direction of the core portion comprising the header tanks to a portion where the header tanks are longitudinally formed; and the blocking plates are formed to block only a part in the length direction of each of the bypass area, wherein the inlet header tank and the outlet header tank are disposed on one side of the core portion in the length direction.

2. The heat exchanger of claim 1 , wherein the inlet header tank and the outlet header tank are disposed at a same position as one another in the length direction.

3. The heat exchanger of claim 2 , wherein a blocking area ratio is a ratio of an area blocked by the blocking plate in the bypass area with respect to the entire bypass area.

4. The heat exchanger of claim 1 , wherein the blocking plate is joined to the core portion.

5. The heat exchanger of claim 1 , wherein the blocking plate has an opening portion formed at an end part thereof in the length direction.

6. The heat exchanger of claim 5 , wherein the opening portion is formed between the tubes of the core portion in the height direction.
