At least one of a relative position and a shape of a hole of the thin plate is changed in a two-dimensional projection plane view, and a thin plate is laminated, and adjacent to each other, a first flow path group that can generate heat transfer in at least two different directions of the thin plate laminate is disposed. The first flow path and the second flow path belonging to the second flow path group.

This heat exchanger is in two different directions in the thin plate laminate, that is, the first heat transfer medium flows in one direction from one side through the first flow path group, and passes through the second side from the other side opposite thereto. The flow path group causes the second heat transfer medium to flow in a direction opposite to the one direction.

According to this heat exchanger, since the first flow path belonging to the first flow path group and the second flow path belonging to the second flow path group are disposed adjacent to each other, the first flow path and the second flow path are close to each other and shortened. The distance from the first flow path to the second flow path. As a result, the heat exchange rate can be increased, for example, between the first heat transfer medium flowing through the first flow path group from one of the high temperature regions and the second heat transfer medium flowing from the low temperature region to the second flow path group. Produces high-efficiency heat transfer and becomes a heat exchanger with a high heat exchange rate.

The plurality of flow paths formed in the laminated body heat exchange unit 17 are formed by the primary flow path 29 of the through hole 25 arranged in a zigzag manner and the secondary flow path 31 arranged in a zigzag manner in the zigzag arrangement.

In the laminated body heat exchange unit 17, the end portion substrate 19 is disposed to the left and right sides in the flow path extending direction. The end substrate 19 is provided with a primary through hole 25 corresponding to one of the positions of the primary flow path 29 in the arrangement of the through holes 25 penetrating the heat exchange portion substrate 13, and is inserted through the corresponding secondary flow. Secondary through hole 25 in one of the positions of the road 31, the present In the embodiment, a pair of through holes 25 are formed through the pair of through holes 25 at both ends in the diagonal direction of the arrangement of the through holes 25 penetrating the heat exchange portion substrate 13.

The first flow path converting portion 21 is disposed between the end portion substrate 19 and the stacked body heat exchange portion 17 of the pair of end portion substrates 19 disposed in the stacked laminate heat exchange portion 17. Further, the second flow path converting portion 23 is disposed between the other end portion substrate 19 and the stacked body heat exchange portion 17.

The first channel converting unit 21 and the second channel converting unit 23 use the same converting unit in the left-right direction. The first flow path conversion unit 21 and the second flow path conversion unit 23 are formed by laminating a plurality of flow path conversion substrates 15 . The flow path conversion substrate 15 has a connection hole 27 formed by connecting at least two through holes which are adjacent to each other in a different direction and different rows in the through hole arrangement of the heat exchange unit substrate 13 . The flow path conversion substrate 15 having a flow path pattern formed by the plurality of through holes 25 independent of the connection hole 27 can be connected to the primary flow path by changing the pair of through holes 25 penetrating the end portion substrate 19 by changing the posture. 29 and the secondary flow path 31.

By this, the pair of through holes 25 that are inserted through the one end substrate 19 are branched into the plurality of primary flow paths 29 and the secondary flow paths 31 of the laminated body heat exchange unit 17 through the first flow path conversion unit 21 . The second flow path conversion unit 23 is assembled and connected to a pair of through holes 25 that are bored in the other end substrate 19 . The hatching (hatched pattern) shown in the second (a) to (f) diagrams shows the fluids of the primary flow path 29 and the secondary flow path 31 of the stacked body heat exchange unit 17 from the end substrate 19 pattern. Left downward The line (hatched line) is a primary fluid flowing through the primary flow path 29, and the right downward slanted line (hatched line) is a secondary fluid flowing through the secondary flow path 31. In other words, the fluid that flows in from the inlet hole 33 of the one end substrate 19 in the second (a) diagram (the oblique line from the left to the lower side (hatched line)) passes through the through hole 25 in the second (b) diagram. 2(c) is branched by the zigzag portion of the connecting hole 27, and is branched by the through hole 25 of the second (d) view and further branched by the zigzag portion of the connecting hole 27 in the second (e) view. And flowing toward the primary flow path 29 of each of the through holes 25 shown in the second (f). In the present embodiment, the flow path toward the laminated body heat exchange unit 17 from the inlet hole 33 of the end portion substrate 19 is in the primary flow path 29 in the example of the second (a) to (f). In the case of flow, when reaching the first and second paragraphs from the lower part of the 2nd (f) diagram, follow the (a), (b), (c), (d), (e), (f) of Fig. 2 The order of (a), (b), (c), (b), (c), (d), (e), (f) in Figure 2, when reaching the third and fourth stages from below. The order, from the bottom to the fifth paragraph, is in accordance with (a), (b), (c), (b), (c), (b), (c), (d), ( The order of e) and (f) causes the fluid to flow, that is, when it reaches the upper part of the third stage from the lower part of the second (f) figure, the second (c), (b) in the opposite direction to the stacking order. After the order of the drawing flows into the connection hole 27, it is necessary to further branch in the connection hole 27 in the order of the second (b) and (c). In other words, the fluid only causes the flow path conversion substrates 15 (the second (b) to (e) diagrams) of the four postures to pass once without passing through the inlet holes 33 toward the respective primary flow paths 29, so that the four types The connection hole 27 of each of the substrates 15 in the posture is in the thickness direction The circulation flows to become the flow of the primary flow path 29 from the first stage toward the fifth stage.

When the heat exchange unit substrate 13 , the flow path conversion substrate 15 , and the end portion substrate 19 are simplified, the heat exchange unit substrate 13 is simplified to A, and the flow path conversion substrate 15 is simplified. Simplified to B, when the end substrate 19 is simplified to E, the fluid flowing in from the inlet hole 33 of the one end substrate 19 (E) is passed through the third state in the integrated state. The connection hole 27 of the first flow path conversion unit 21 formed in B in the figure is branched, and flows into the primary flow path 29 or the secondary flow formed by each of the through holes 25 of the laminated body heat exchange unit 17 of A in Fig. 3 . The flow path 31 performs heat exchange. Then, the connection hole 27 of the second flow path conversion unit 23 indicated by B is collected and flows out from the outlet hole 35 of the end substrate 19 (E).

Here, the through holes 25 penetrating through the flow path converting substrate 15 of the heat exchanger 11 are arranged, for example, in two rows and three stages having the smallest configuration. The patterns from the 1st column to the 3rd column of the 1st column and the 2nd column shown in the 2nd (b) figure are the same. Further, the mode of this Fig. 7(b) is also the same.

The flow path conversion substrate 55 is formed with a connection hole 59 that connects the two through holes 25 that are adjacent to each other in different stages and different rows. In this example, the through hole 25 in the third row of the first row is a coupling hole 59 that is connected to the through hole 25 in the second row of the second row (Fig. 7(b)). Therefore, the through holes 25 of the first stage are independent through holes. The flow path conversion substrate 15 has four types of flow path modes in which the posture is changed to the basic posture, the vertical reverse posture, the left and right reverse posture, and the up, down, left, and right reverse postures.

The four flow path conversion substrates 55 that have changed the postures are stacked in the above-described posture, and a pair of through holes 25 that are positioned at both ends in the diagonal direction in two rows and three stages are connected to the laminated body heat exchange unit. The primary flow path 29 of the zigzag arrangement of 17 and the secondary flow path 31 arranged in a zigzag manner with the zigzag arrangement in the reverse direction. As a result, by using one type of flow path conversion substrate 55, a pair of through holes 25 of the end portion substrate 53 can be branched or collectively connected to the plurality of primary flow paths 29 and secondary flow paths 31.

In the heat exchanger 11, the posture of the flow path converting substrate 25 when the flow path converting substrate 55 is laminated can be easily grasped by the indicator portions 37, 39, and 41. Therefore, the basic posture (Fig. 7(b)), the up-and-down reverse posture (Fig. 7(c)), the left-right reverse posture (7th (d)), and the up, down, left, and right reverse postures (7th) The order of (e) diagram) is easy to stack without error. As a result, four sets of the flow path conversion substrates 55 of one type can be easily used by the positions of the indicator portions 37, 39, and 41, respectively.

In addition, the arrangement of the two rows and the three segments of the minimum configuration constitutes the substrate shown in Fig. 7 as well as the hatching (hatched pattern) shown in Fig. 2 in the above embodiment, and the seventh (a) to (f) The hatching (hatched pattern) shown in the figure is a pattern indicating the respective fluids of the primary flow path 29 and the secondary flow path 31 of the heat exchange substrate 57 from the end substrate 53 from the left to the downward slant (hatched) For the primary fluid flowing in the primary flow path 29, the right downward slanted line (hatched line) is the secondary fluid flowing through the secondary flow path 31.
