Heat Exchanging Plate And Plate-type Heat Exchanger configurating to stack the same}

The present invention relates to a plate heat exchanger, and more particularly, to a plate heat exchanger consisting of a plate heat exchanger and a stack thereof to optimize the flow distribution of the heat exchange medium and to improve the flow pressure distribution of the heat exchange medium.

The heat exchanger generally includes a pair of header tanks through which the heat exchange medium is introduced and discharged, and a tube which connects the header tanks and distributes the heat exchange medium therein to perform heat exchange. At this time, the heat exchanger can be divided into two types. The fin-tube type heat exchanger is formed by inserting a plurality of tubes into a tank, and the plate type heat exchanger in which a plurality of plates are stacked to form a tube part and a tank part. It can be divided into a plate heat exchanger. The plate heat exchanger is widely used because it is easier to assemble than the fin-tube type heat exchanger, the productivity is small because the number of required parts is good, and the volume can be reduced, which is advantageous for securing the engine room space. In particular, the plate heat exchanger changes the shape of the plate to allow a more complicated and diversified flow path design than the fin-tube type heat exchanger. Accordingly, the plate heat exchanger is preferably applied to heat exchange between two kinds of fluids such as a water-cooled oil cooler and causing heat exchange with each other.

Meanwhile, the conventional plate heat exchanger determines heat exchange efficiency by considering only the area and pitch of the Severon formed on the heat exchanger plate, and does not consider the direction or pressure loss of the fluid flowing in the plate heat exchanger. In particular, a method of increasing the stacking amount of the plate heat exchanger was used as a method for releasing the pressure loss, which causes a problem of increasing the size and weight of the heat exchanger. In addition, the flow of fluid in the plate heat exchanger is essential for proper fluid heat exchange, but in the related art, the flow distribution of the fluid is not properly made on the plate heat exchanger because the consideration of the flow of the fluid has not been made properly.

Therefore, an object of the present invention is to solve the problems of the prior art as described above, by providing channels that can improve the flow path of the fluid to improve the heat exchange efficiency of the entire plate heat exchanger and high performance at low pressure loss Branch is to provide a plate heat exchanger consisting of a plate heat exchanger and a stack thereof.

Accordingly, the sebron portion 50 serves as a passage while the fluid introduced from the first fluid inlet 11 flows through the first fluid outlet 12, and the heat energy and the sebron portion 50 of the fluid are present. It has a role of exchanging heat energy. In particular, since the plate heat exchanger 30 of the present invention has a structure in which a plurality of plate heat exchangers are stacked in a multi-layer structure, thermal energy due to fluid flowing in the other plate heat exchanger may be transferred to the plate heat exchanger through the Sevron unit 50. To support heat exchange with the fluid flowing in the The Sevron portion 50 is formed with the Sevron patterns are arranged from one side of the plate 51 to the other side. In other words, the sebron portion 50 is repeatedly disposed while maintaining a predetermined vertical interval between the first V-shaped pattern in the longitudinal direction between the first fluid inlet 11 and the first fluid outlet (12).

That is, the fluid distribution guide 57 may be provided in a diagonal direction upward from the first fluid inlet 11 based on the plate 51 length direction. The fluid distribution guide 57 may be formed to expose the bottom surface of the plate 51 by removing the patterns of the sebron part 50 and may be formed to have a predetermined length. For example, the fluid distribution guide 57 removes a part of the pattern of the plurality of sebron portions 50 from the first fluid inlet 11, but is separated from the first fluid inlet 11 by the sebron portion 50 farthest. It may be provided in a form that crosses the pattern of the plurality of sebron portion 50 to be connected to the peak or valley portion of the pattern of). For this reason, the fluid distribution guide 57 may serve as a passage to allow the fluid to be easily moved to the center portion of the sebron portion 50 when the fluid is introduced from the first fluid inlet 11. As a result, the fluid distribution guide 57 allows the fluid to move more quickly and to the center of the sebron portion 50, i. Support flow distribution.

The fluid flow adjustment jaw 59 is provided at one end of the sebron portion 50 so that the fluid flows through the center portion of the sebron portion 50 to the fluid outlet.

As shown in the figure, the fluid flow adjustment jaw 59 may be bent so that a predetermined region of some of the Sevron patterns 52 is arranged in the longitudinal direction. Accordingly, some of the Sevron patterns 52 provided with the fluid flow adjusting jaw 59 may include a direction groove disposed in the longitudinal direction of the plate 51. The directional grooves are provided to allow the fluid introduced from the first fluid inlet 11 to enter, and as a result, the fluid introduced through the first fluid inlet 11 based on the corresponding directional grooves is in the longitudinal direction of the plate 51. It is easier to move to the first fluid outlet 12 via the sebron portion 50.

The outer wall 60 may be formed to be perpendicular to the bottom surface of the plate 51 at the outer side of the plate 51 to surround the bottom surface of the plate 51 and the sebron portion 50. A constant groove may be provided between the outer wall 60 and the plate 51, and the groove may serve as a passage through which the fluid introduced through the fluid inlet moves. The height of the outer wall 60 may be formed higher than the pitch of the sebron portion 50, and the inner surface of the outer wall 60 may face the outer wall of the other plate heat exchange part when the other plate heat exchange part is stacked.

In addition, the fluid inlet or the fluid outlet formed in each of the first plate heat exchange part 31 and the second plate heat exchange part 32 has a separate gap between the structure in which the peripheral area of the hole protrudes and the structure in which the recessed shape is engaged with each other. It can be arranged in an unshaped form. For example, when the first plate heat exchanger 31 and the second plate heat exchanger 32 are stacked in the form shown in FIG. 4, the first fluid inlet 11 and the first fluid outlet 12 are recessed, respectively. The structure and the protruding structure may be engaged with each other to provide a predetermined space.
