Refrigerator

1. A refrigerator comprising:

a storage compartment;

a cooling compartment configured to receive a evaporator;

a duct module positioned between the storage compartment and the cooling compartment to partition the storage compartment and the cooling compartment in a front and rear direction; and

a blowing fan disposed in the duct module to suck air in the cooling compartment and discharge air to the storage compartment,

wherein the duct module comprises:

a front panel; and

a rear panel coupled to a rear side of the front panel by contacting continuously on three sides to form a flow path with the front panel,

wherein the rear panel comprises:

a plurality of flow path forming protrusions configured to form a flow path by protruding from the rear panel to the front panel; and

at least one sealing surface configured to be extended from the plurality of flow path forming protrusions to be parallel with the front panel, to make a surface contact with the front panel,

wherein the front panel comprises at least one sealing protrusion protruding from the front panel toward the rear panel, to make a surface contact with the plurality of flow path forming protrusions, to form an area on the front panel, and the at least one sealing protrusion is formed in a shape corresponding to a shape of an inner surfaces of at least one of the plurality of flow path forming protrusions to support at least one of the plurality of flow path forming protrusions,

wherein the at least one sealing surface protrudes toward an area on the front panel formed by the at least one sealing protrusion to fill the area on the front panel formed by the at least one sealing protrusion.

2. The refrigerator of claim 1 , wherein the at least one sealing surface is extended to have a width, wherein the width of the at least one sealing surface is equal to or greater than 25 mm.

3. The refrigerator of claim 1 , wherein the at least one sealing surface and the at least one sealing protrusion are extended to each have a width, wherein a sum of the width of one of the at least one sealing surface and the width of one of the at least one sealing protrusion is equal to or greater than 25 mm.

4. The refrigerator of claim 1 , further comprising:

a plurality of locking hooks protruding from an end of any one of the front panel and the rear panel to an end of another of the front panel and the rear panel, and

a plurality of locking grooves formed in a concave shape on an end of the other of the front panel and the rear panel, to be engaged with the plurality of locking hooks.

5. The refrigerator of claim 1 , wherein:

the plurality of flow path forming protrusions comprises a pair of flow path forming protrusions disposed separated in a left and right side, and a single flow path forming protrusion provided to be inclined downward in a left and right direction between the pair of flow path forming protrusions; and

the at least one sealing surface comprises a pair of sealing surfaces extended from the pair of the flow path forming protrusions to an outside, and a single sealing surface formed inside of the single flow path forming protrusion inclined downward in the left and right direction.

6. The refrigerator of claim 1 , further comprising:

a body provided with the storage compartment and the cooling compartment partitioned in the front and rear direction by the duct module.

7. The refrigerator of claim 6 , wherein the storage compartment comprises a refrigerating compartment and a freezing compartment provided in an upper portion and a lower portion of the body, and

wherein the duct module is installed in at least one of the refrigerating compartment and the freezing compartment.
