FIELD OF THE INVENTION
The present invention relates to a heat exchanger equipped with a cold reserving part and a manufacturing method thereof, and more particularly, to a heat exchanger equipped with a cold reserving part, in which since a cold reserving material charging part is formed at a portion at which an inlet and outlet member is formed, an additionally protruding part to inject the cold reserving material is not required, such that the heat exchanger may be miniaturized and may more rapidly and effectively absorb cold air to increase a cold reserving effect, and a manufacturing method of a heat exchanger equipped with a cold reserving part which forms the cold reserving material charging part to charge the cold reserving material after coating the heat exchanger to block a coating solution from being introduced into the heat exchanger, thereby preventing the heat exchanger from corroding due to the coating solution to increase durability and more increase manufacturing performance.
BACKGROUND OF THE INVENTION
In the recent automotive industry, as the interest in environment and energy is increased around the world, research into improvement in fuel efficiency has been conducted and a research and development to implement weight reduction, miniaturization, and multi-functional performance to meet various consumer needs has been continuously conducted. In particular, a research and development for a hybrid vehicle simultaneously using power and electric energy tends to be increased.
The hybrid vehicle has mainly adopted an idle stop/go system which automatically stops an engine at the time of stopping, such as waiting for signal, and restarts the engine by operating a transmission again. However, even in the case of the hybrid vehicle, since an air conditioner is operated by the engine, when the engine stops, a compressor also stops, such that a temperature of an evaporator rises and thus comfortableness of a user deteriorates. Further, since a refrigerant inside the evaporator is easily evaporated even in a room temperature, the refrigerant is evaporated for a short period of time in which the compressor is not operated. Therefore, even though the engine is operated again to operate the compressor and the evaporator, there is a need to compress and liquefy the evaporated refrigerant, such that it takes much time to supply a cold wind to the interior of a room and the entire energy consumption may be increased.
Meanwhile, Japanese Patent Laid-Open Publication No. 2000-205777 (Title of the Invention: Heat Storage Heat Exchanger) has been proposed to increase cooling efficiency, which is illustrated in FIG. 1.
As illustrated in FIG. 1, the heat storage heat exchanger is characterized in that a heat exchange medium passage 191e through which a heat exchange medium is distributed and heat storage material chambers 191f and 191f′ in which a heat storage material is stored are integrally formed by a tube 191 having a double pipe structure and an outside of the tube 191 having a double pipe structure is provided with a passage 194 through which a fluid heat-exchanged with the heat exchange medium is formed.
However, as illustrated in FIG. 1, the heat storage heat exchanger includes the tube formed by bonding several boards to each other, such that the bonding defect may frequently occur, is formed to have the double pipe structure, such that it is difficult to be manufactured, and has a problem in that the heat exchange medium therein is mixed with the heat storage material when the bonding defect occurs. Further, even though the bonding defect occurs, it is difficult to find out the bonding defect portion.
Further, the heat storage heat exchanger has a problem in that since the inside of the double pipe is provided with a passage through which the heat exchange medium moves and the outside thereof is provided with the heat reserving material chamber in which the heat reserving material is formed, the heat storage material easily stores the cold air of the heat exchange medium therein but air passing through the outside of the double pipe structure contacts the heat reserving material chamber to reduce a heat transfer of the heat exchange medium. Further, a fin inserted into the outside of the double pipe tube also contacts the heat storage material chamber but is not directly connected to the heat exchange medium passage, thereby reducing the heat exchange efficiency.
To solve the above-mentioned problem, the present applicant has proposed Korean Patent Laid-Open Publication No. 2007-0111390 (Title of the Invention: Cold Reserving Part Equipped Evaporator), which is illustrated in FIG. 2.
In Korean Patent Laid-Open Publication No. 2007-0111390 illustrated in FIG. 2, a tube 30 formed by bonding a pair of plates 10 having left and right sides each provided with refrigerant passages 11a and 11b is used and a cold reserving part 20 in which a cold reserving material is stored is formed between the refrigerant passages 11a and 11b of the tube 30.
Meanwhile, the heat exchanger equipped with a cold reserving part has a problem in that as the refrigerant and the cold reserving material each move, a component to charge a cold reserving material is required along with a pipe for providing the introduction and discharging of a refrigerant and when a component for charging the cold reserving material protrudes to the outside, it is difficult to prevent miniaturization and a space in which the refrigerant moves or a storage space in which the cold reserving material is stored is reduced so much.
Further, since condensed water may be formed on an outer surface of the heat exchanger for air conditioning, the heat exchanger easily discharges the condensed water by coating a coating solution on the outer surface thereof, suppresses a smell from occurring, and suppresses inhabitation of mold, and the like.
Generally, the coating processing dips the heat exchanger in a coating solution and dries the coating solution to form a coating layer and the coating solution introduced into the heat exchanger may corrode the heat exchanger and thus reduce the overall durability of the heat exchanger.
However, the heat exchanger equipped with a cold reserving part has a problem in that it is highly likely to introduce the coating solution into the heat exchanger through a part to charge the cold reserving material and thus a separate process to seal the part to charge the cold reserving material is required.
In addition, the heat exchanger equipped with a cold reserving part according to the related art illustrated in FIG. 1 has the double pipe form and when the coating solution is introduced into the heat exchanger, hardly removes the coating solution, such that the occurrence frequency of defects may be increased due to the introduction of the coating solution, thereby causing the reduction in productivity.
Therefore, a need exists for a heat exchanger to be able to expect the rapid and high cold reserving performance, prevent corrosion due to the coating solution, and increase the durability and manufacturing performance.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE INVENTION
Hereinafter, exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
A heat exchanger 1000 equipped with a cold reserving part according to an exemplary embodiment of the present invention is configured to include a first header tank 201, a second header tank 202, tubes 110 of three columns, and an inlet and outlet forming member 300, and a cold reserving material charging part 610.
The first header tank 201 and the second header tank 202 are disposed in parallel to be spaced apart from each other at a predetermined distance and are partitioned in an air flow direction (width direction) by a barrier rib 213 to include a first compartment 213a to a third compartment 213c formed therein.
The first header tank 201 and the second header tank 202 are provided with the inlet and outlet forming member 300 to be introduced with a heat exchange medium and move the heat exchange medium to the tube 110 and forms a space from which the heat exchange medium is discharged again.
The first header tank 201 and the second header tank 202 may be formed by a coupling of a header 210 and a tank 220, in which the header 210 may include a plane part 211, a coupling part 212, and the barrier rib 213.
The plane part 211 has a configuration in which a tube insertion hole 211-1 is hollowed so that an end of the tube 110 is inserted and has a plate shape.
The coupling part 212 is configured to extend in a width direction of the heat exchanger and extend in a height direction at both ends of the plane part 211 to form an entire cross section of the header 210 in a “”-letter shape and adheres to the tank 220 to serve to fix the tank 220.
The barrier rib 213 is configured to partition the first compartment 213a which protrudes on the plane part 211 in the same direction as the coupling part 212 to communicate with a first column of the tube 110, the second compartment 213b which communicates with a second column of the tube 110, and the third compartment 213c which communicates with a third column of the tube 110.
FIG. 3 illustrates an example in which the barrier rib 213 is integrally formed with the header 210.
The tubes 110 of three columns have both ends fixed to the first compartment 213a to the third compartment 213c of the first header tank 201 and the second header tank 202, respectively.
One of the first to third columns of the tube 110 is stored with a cold reserving material and the heat exchange medium moves in the rest two thereof.
As illustrated in FIG. 3, in the heat exchanger equipped with the cold reserving part, the heat exchange medium moves in the tubes 110 of the first column and the third column, the cold reserving material may be stored in the tube 110 of the second column, and the cold reserving material charging part 610 may be formed to communicate with the second compartment 213b. 
However, the heat exchange medium also moves in the first compartment 213a of the first header tank 201 and the second header tank 202 which communicates with the first column and the third compartment 213c of the first header tank 201 and the second header tank 202 which communicates with the third column.
