Cold storage heat exchanger {COLD RESERVING HEAT EXCHANGER}

The present invention relates to a cold storage heat exchanger of the present invention. More specifically, the present invention provides cooling of a user by using cold air by a cold storage material while maintaining heat exchange performance by maintaining a heat exchange medium and a cold storage material at the same time in the last row in the air flow direction. The present invention relates to a cold storage heat exchanger capable of improving comfort.

In recent years, as the interest in the environment and energy in the automobile industry is increasing, researches for improving fuel efficiency have been conducted, and research and development for light weight, miniaturization, and high functionalization have been steadily made to satisfy various consumer needs. In particular, research and development of hybrid vehicles using both power and electric energy are increasing.

The hybrid vehicle often adopts an idle stop / high system that automatically stops the engine when the vehicle stops, such as signal waiting, and restarts the engine by operating the transmission. However, even in the case of the hybrid vehicle, since the air conditioner is operated by the engine, when the engine is stopped, the compressor is also stopped, thereby increasing the temperature of the evaporator, thereby lowering the user's comfort. In addition, since the refrigerant inside the evaporator is easily vaporized even at room temperature, the refrigerant is vaporized for a short period of time when the compressor is not operated, and the engine is operated again. Not only does it take a long time, but there is a problem of increasing the overall energy requirement.

In addition, the cold storage heat exchanger (1000) of the present invention has a simple configuration, which has an advantage of further improving productivity.

The cold storage heat exchanger 1000 of the present invention may be variously modified by modifying the shape of the partition plate 105, the shape of the tube 200, and the like.

First, in the cold storage heat exchanger 1000 of the present invention shown in FIG. 5 and FIG. 6, the tube 200 forming the rearmost column in the air flow direction includes the first space part S1 and the second space part S2. ) And the tube 200 forming the last row by alternately communicating with the heat exchange medium and the coolant are alternately positioned.

In the region where the coolant is stored, the number of tubes 200 communicating with the first space S1 may be adjusted, and the location of the coolant may be adjusted to adjust the position of the coolant. have.

On the other hand, the tube 200, the first header tank 110 and the second header tank 120 forming the rearmost column forms a space in which the coolant is stored, a region where the heat exchange medium can flow. Since this may be reduced, the width W100-1 of the portion forming the rearmost row in the air flow direction in which the partition plates 105 of the first header tank 110 and the second header tank 120 are provided is the remaining width. It can be formed larger than the width (W100-2) of the portion forming the row (W100-1 > W100-2), and thus the width (W200-1) of the tube 200 is also provided in the tube 200 of the other row ) The pole (W200-2) beam can be formed larger (W200-1> W200-2). (See Figures 3 and 4)

In addition, the cold storage heat exchanger 1000 of the present invention may vary not only the width of the tube 200 but also the width of the tube 200 to vary the flow rate of the heat exchange medium or the storage amount of the coolant. The pitch of the pins 300 provided between the 200 may also be variously formed.

7 and 8, the cold storage heat exchanger 1000 illustrated in FIGS. 7 and 8 has the same length as the tube 200, and the partition plate 105 includes the first header tank 110 and the second header tank 120. An example in which the concave portion 105a, which is a concave plate portion, and the convex portion 105b, which is a convex portion, is formed in a concave-convex shape in the longitudinal direction of is shown.

At this time, the insertion depth of the tube 200 is such that the end of the tube 200 is located between the concave portion 105a and the convex portion 105b of the partition plate 105 in the height direction, and the concave region The tube insertion hole 106 is formed so that the tube 200 can be inserted into the tube 200.

That is, the cold storage heat exchanger 1000 shown in FIGS. 7 and 8 has the same length of the tube 200, and uses the partition plate 105 having an uneven shape, and the tube 200 in which the cold storage material is stored. ) And the tube 200 in which the heat exchange medium flows are alternately formed, but the width of the concave or convex region may be modified, and the region in which the coolant is stored and the region in which the heat exchange medium flows are reversed. It may be formed.

In the cold storage heat exchanger (1000) of the present invention, the cold storage material is charged into the partial tube (200) of the rearmost row in the air flow direction to effectively store the cold air of the heat exchange medium, and discharge the cold air when the engine is stopped, thereby causing a rapid temperature inside the vehicle. By preventing the rise, there is an advantage that can effectively improve the cooling comfort of the user by effectively storing the cold air by the cold storage material even in a simple configuration.
