Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat exchanger,

The present invention relates to a cold-storage heat exchanger, and more particularly, to a cold-storage heat exchanger, which is formed on a side where a hot-water supply member is formed on a side where an inlet / outlet member is formed, And to increase the composition of the heat exchanger.

In recent years, as the interest in environment and energy in the automobile industry has been increasing worldwide, researches for improvement of fuel efficiency have been conducted. Research and development for weight reduction, miniaturization and high performance have been made steadily in order to satisfy various consumer needs. In particular, research and development on hybrid vehicles using both power and electric energy are increasing.

The hybrid vehicle often employs an idle stop / hitch system that automatically stops the engine when the vehicle is stopped in a signal waiting state and then restarts the engine with the operation of the transmission. However, even in the case of the hybrid vehicle, since the cooling apparatus is operated by the engine, when the engine is stopped, the compressor is also stopped, thereby raising the temperature of the evaporator and deteriorating the comfort of the user. Also, since the refrigerant in the evaporator is easily vaporized at room temperature, the refrigerant is vaporized for a short period of time in which the compressor is not operated, and the engine is operated again so that the evaporated refrigerant is compressed and liquefied even if the compressor and the evaporator are operated. Not only a long time is required but also an increase in the total energy requirement.

On the other hand, Japanese Patent Application Laid-Open No. 2000-205777 (entitled Heat Storage Heat Exchanger) has been proposed in order to increase the cooling efficiency, which is shown in Fig.

1 has a heat exchange medium passage 191e through which a heat exchange medium flows and a heat storage chamber 191f or 191f 'in which a heat storage material is stored by a tube 191 having a double pipe structure. , And a passage (194) for fluid to be heat-exchanged with the heat exchange medium is formed outside the tube (191) of the double pipe structure.

However, in the heat storage heat exchanger as shown in FIG. 1, since the tube is formed by joining a plurality of plate materials, the occurrence of defective junction is high and the tube is formed in a double pipe shape, There is a possibility that the internal heat exchange medium and the heat storage material are mixed. Further, even if a bonding failure occurs, there is a problem that it is difficult to find the portion.

In addition, the heat storage heat exchanger has a heat storage material chamber in which a passage through which the heat exchange medium is moved is formed inside the double tube and a heat storage material is stored in the outer side, so that the heat storage material is easy to store the cold air of the heat exchange medium therein, Since the air passing through the outside of the heat exchange medium is in contact with the heat storage chamber, heat transfer of the heat exchange medium is deteriorated. In addition, the fins interposed in the outside of the double pipe tube are also in contact with the heat storage material chamber, and are not directly connected to the heat exchange medium passage, thereby reducing heat exchange efficiency.

In order to solve the above-mentioned problems, the present applicant has proposed Korean Patent Publication No. 2007-0111390 (entitled " Evaporator Having a Cooling Unit "), which is shown in FIG.

Korean Patent Laid-Open Publication No. 2007-0111390 shown in Fig. 2 uses a tube 30 formed by joining a pair of plates 10 formed with left and right refrigerant passages 11a and 11b, (20) in which the axial coolant is stored is formed between the refrigerant passages (11a) and (11b) of the refrigerant passage (30).

On the other hand, as the refrigerant and the axial coolant flow respectively, the coaxial heat exchanger needs a structure for charging the axial coolant together with the pipe for the inflow and discharge of the coolant. When the component for charging the axial coolant is protruded to the outside, There is a problem that the space for the refrigerant to flow or the storage space for the coolant is reduced.

Accordingly, there is a demand for a heat exchanger capable of achieving miniaturization and quick cooling performance while increasing the productivity.
