Abstract

Provided is a heat exchanger. The heat exchanger includes: a core portion configured to have a cooling water channel provided therein; a housing configured to have a concave shape to have the core portion inserted thereinto so that the core portion is housed therein and have one side provided with an air inlet into which air is introduced and the other side provided with an air outlet through which the air is discharged; and a sealing member configured to be interposed between an outer side of the core portion and an inner side of the housing to seal between the core portion and the housing, thereby preventing air from being bypassed between the core portion and the housing to improve heat exchange efficiency and heat exchange performance.

Claims

1. A heat exchanger, comprising:

a core portion configured to include an inlet tank portion and an outlet tank portion having a space in which cooling water is stored and flows, a plurality of tubes having both ends connected to the tank portions to form a cooling water channel, and fins interposed between the tubes;

a housing configured to have a concave shape to have the core portion inserted thereinto so that the core portion is housed therein and have one side provided with an air inlet into which air is introduced and the other side provided with an air outlet through which the air is discharged; and

an elastic sealing member configured to be interposed between an outer side of the core portion and an inner side of the housing to seal between the core portion and the housing,

wherein both longitudinal inner side surfaces and a bottom surface of the housing are concavely provided with a joining groove to insert one side of the sealing member into the joining groove,

wherein both longitudinal outer side surfaces and a bottom surface of the core portion are concavely provided with a fitting groove to insert the other side of the sealing member into the fitting groove,

the fitting groove being wider than the sealing member so as to be spaced apart from the sealing member,

wherein the other side of the sealing member protruding inwardly from the longitudinal side surfaces of the housing has a length larger than a width, in a state in which one side of the sealing member is inserted and joined into the joining groove of the housing, and

wherein the other side of the sealing member is inserted in such a manner as to be spaced apart from inner side surfaces of the fitting groove, and is configured such that when the air is introduced into the housing, the other side of the sealing member is bent by a pressure of the introduced air and a lateral side surface of the sealing member opposite to an air-introduced direction adheres to one of the lateral side surfaces of the fitting groove opposite to the air-introduced direction.

2. The heat exchanger of claim 1, wherein the inner side of the housing and the outer side of the core portion are spaced apart from each other.

3. The heat exchanger of claim 1, wherein a longitudinal side surface of the other side of the sealing member is formed to have a narrower width than the one side of the sealing member.

4. The heat exchanger of claim 1, wherein the housing is concavely provided with a fixed groove so that the fixed groove is connected to the joining groove, and one side of the sealing member inserted into the joining groove of the housing is protrudedly provided with a fixed protrusion to insert the fixed protrusion into the fixed groove;

wherein the fixed protrusion protrudes from one side or both sides in a width direction, and wherein the fixed protrusion is inserted into the fixed groove such that the sealing member firmly fixed to the housing, and

wherein the movement of the sealing member is limited to be prevented from moving in the height direction and the longitudinal direction.

5. The heat exchanger of claim 1, wherein the other side of the sealing member is disposed to be spaced apart from the fitting groove of the core portion.

6. The heat exchanger of claim 1, wherein the bottom surface of the core portion is provided with a support portion protruding downwardly, wherein the support portion is inserted into a sealing groove formed in the bottom surface of the housing.
