The protruding beads 600 are bonded to each other by alternate lamination of the first plate 500a and the second plate 500b.

Second, an example in which the third plate 500c is further formed to form the protruding bead 600 (see FIG. 5) is the same as that described above except that the protruding bead 600 is formed The first plate 500a and the second plate 500b of the first plate 500a and the second plate 500b of the first plate 500a are used. A third plate 500c in which hollow first to fourth hollow portions 571 to 574 are formed so that the first to fourth communication holes 510 to 540 are penetrated in the form of a plate in which the first to fourth communication holes 510 to 440 are formed, Respectively.

The first hollow portion 571 is connected to the first communication hole 510 while the second hollow portion 572 is connected to the second communication hole 510 and the third hollow portion 573 is connected to the third In the communication hole 530, the fourth hollow portion 574 is formed to correspond to the fourth communication hole 540.

More specifically, the plate type heat exchanger 1000 of the present invention includes a third plate 500c, which is formed by alternately stacking the first plate 500a and the second plate 500b and forms the protruding bead 600, May be formed on the first plate (500a) or the second plate (500b) forming the first fluid part (501).

5, a plate portion of the third plate 500c is joined to the first plate 500a, and a second plate 500b, which forms the first plate 500a and the first fluid portion 501, A protruding bead 600 protruding from the protruding bead 600 is formed.

At this time, the third plate 500c may adjust the height of the protruding bead 600 so that the end of the protruding bead 600 is bonded to the second plate 500b.

The protruding bead 600 may include a first bead 610 and a second bead 620 to a sixth bead 660.

The first bead 610 is formed along a first reference line L 1 connecting the first inlet pipe 100 and the first outlet pipe 200.

The first beads 610 are provided along the first reference line L1 and the total length of the first beads 610 is 30 to 100 times the length Lt of the first reference line L1. 60 (%).

In the drawing, the length of the center first bead 611 is Lb, the length of the auxiliary first bead 612 is La, and the length of the first reference line L1 is Lt.

The total length of the first beads 610 is a length including the thickness of the material when viewed from the upper side in the stacking direction of the plate 500. The length of the central first bead 611 and the length of the auxiliary first bead 611, And the length of the beads 612, and in the case of the embodiment shown in the drawing, Lb + La x 2.

7, the relationship between the first baseline length Lt connecting the first heat exchange medium inlet / outlet section (first inlet pipe 100 and first outlet pipe 200) to the first bead formation total length 610 And when the ratio of the first baseline length Lt to the total length 610 of the first bead 610 is less than 30%, it is insufficient in durability, and when the ratio is more than 60%, the pressure drop is increased more than the predetermined value Can be confirmed.

In the plate heat exchanger 1000 of the present invention, the first bead 610 is provided in an odd number, and the center first bead 611 positioned at the center is positioned at a distance of 1.5 to 3 times the length of the remaining auxiliary first bead 612 It is preferable that it is formed as a double.

The fourth bead 640 is adjacent to the third communication hole 530 and the fourth communication hole 540. The fourth bead 640 adjacent to the third communication hole 530 may be formed by The first heat exchange medium flowing through the first inlet pipe 100 is stably branched and moved along the third communication hole 530 and the fourth bead 640 adjacent to the fourth communication hole 540 The first heat exchange medium is diverged along the fourth communication hole 540, and then stagnated at the corner portion and stably merged again.

In the figure, the fourth bead 640 is formed at a half of an angle between the first reference line L1 and the fourth reference line L4, and the first reference line L1 and the fifth reference line L5). The medium is guided so that the first heat exchange medium is directed to the L1 and L4 central regions, and is positioned at the central portions of L1 and L4 to enhance the durability.

The fifth bead 650 may be formed in the inner space formed by the first bead 610, the second bead 620, and the third bead 630 when viewed from above in the stacking direction of the plate 500. [ The first heat exchange medium introduced through the first inlet pipe 100 is guided to the second bead 620 side and the first heat exchange medium having passed through the second bead 620 flows through the first outlet pipe 200, As shown in FIG.

The plate heat exchanger 1000 is formed in a long shape in the transverse direction of the plate 500 so that the distance between the first communication hole 510 and the second communication hole 520 and the distance between the second bead 620 The fifth bead 650 guides the flow of the first heat exchange medium through the second bead 620 or through the second bead 620. [

The second bead 620 to the fifth bead 650 may be formed to have the same shape and length as the auxiliary first bead 612 to facilitate the manufacture of the plate.

The sixth bead 660 is not provided with the first bead 610 and the fifth bead 650 of the plate 500 and is added for the purpose of enhancing durability. It is preferably formed in a circular cross-sectional shape so as to be minimized.

The sixth bead 660 is preferably positioned above a seventh reference line L7 connecting the centers of the second inlet pipe 300 and the second outlet pipe 400.

Referring to FIG. 4, the first heat exchange medium flowing through the first inlet pipe 100 flows through the first communication hole (not shown) 510 and is moved along the space of the first fluid part 501 formed on the upper side of the first plate 500a and moved upward along the second communication hole 520, 1 exit pipe 200 (indicated by a thick line in Fig. 4)

The second heat exchange medium flowing through the second inlet pipe 300 is moved downward along the third communication hole 530 and the second fluid exchange unit 502), moves upward along the fourth communication hole 540, and is discharged through the second outlet pipe 400 (indicated by a thin line in FIG. 4).

4, as the protruding bead 600 is formed, the plate-type heat exchanger 1000 of the present invention can guide the flow of the first heat exchange medium to minimize the amount of pressure drop, There is an advantage that sufficient durability can be secured even without an inner pin.

In fact, FIG. 8 is a graph showing the water resistance of the plate-type heat exchanger 1000 according to the present invention, and shows the relationship between the present invention of the embodiment shown in FIG. 3, The water resistance of Comparative Example 2, which does not exist, was compared.

As described in the conventional problem, in the case of Comparative Example 1 in which the fins exist, it can be confirmed that the flow resistance of the first heat exchange medium is not smooth as the flow resistance of the first heat exchange medium is increased.

On the contrary, the present invention is lower than the water flow resistance of Comparative Example 2 in which no fins are present, and even if the flow amount of the first heat exchange medium is increased, the rise width is not large, and the flow of the heat exchange medium is smooth.

That is, the plate-type heat exchanger 1000 of the present invention is advantageous in that it can secure sufficient durability while smoothly flowing the heat exchange medium.

Also, the protruding bead 600 can guide the first heat exchange medium to improve heat exchange efficiency.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
