Flow channel forming device

Abstract

To provide a flow path forming device capable of making mutually independent flow paths three-dimensionally intersect with each other while reducing the number of members to be connected.SOLUTION: A flow path forming device 10 comprises a structure 12 including a first fluid flow path 121 and a second fluid flow path 122 that are independent of each other. The first fluid flow path 121 and the second fluid flow path 122 are arranged so that some of them three-dimensionally intersect in a specified assembly direction Du. The structure 12 is configured such that two divided bodies such as a first member 14 and a second member 16 are integrally connected in a state of being assembled in the assembly direction Du.SELECTED DRAWING: Figure 2

Claims

When, among the fluid channels that intersect in three dimensions, the channel located on one side in the assembly direction is designated as the first channel, and the channel located on the other side in the assembly direction is designated as the second channel, The first flow path is formed such that at least a portion of it is surrounded by first flow path portions (141, 182, 183, 143) formed on the first member and second flow path portions (162, 22, 23) formed on the second member at a position facing the first flow path portions in the assembly direction. The second flow path is formed surrounded by a third flow path portion (161, 211-216) formed in the second member, a fourth flow path portion (142, 181) formed in the first member at a position facing the third flow path portion in the assembly direction, and an intersection forming portion (162a, 22, 23, 167a) provided in the second flow path portion at a position where the first flow path and the second flow path intersect in three dimensions. The first channel and the second channel are separated by the intersection formation portion. The first member is a molded product in which the first flow channel portion and the fourth flow channel portion are integrally molded. A channel forming apparatus, wherein the second member is a molded product in which the second channel portion and the third channel portion are integrally molded.

2. The first flow channel portion is a first recess (141, 182, 183) formed in the first member and open to the other side in the assembly direction, The second flow channel portion is a second cover portion (162, 22, 23) formed in the second member at a position facing the first recess in the assembly direction, The third flow channel portion is a second recess (161, 211-216) formed in the second member and having a portion that is open to one side in the assembly direction, The flow path forming apparatus according to claim 1, wherein the fourth flow path portion is a first lid portion (142, 181) formed on the first member at a position facing the second recess in the assembly direction.

3. The second flow channel portion is a first recess (167) formed in the second member and open to one side in the assembly direction, The first flow channel portion is a first cover portion (143) formed in the first member at a position facing the first recess in the assembly direction, The third flow channel portion is a second recess (161) formed in the second member and having a portion that is open to one side in the assembly direction, The flow path forming apparatus according to claim 1, wherein the fourth flow path portion is a second cover portion (142) formed in the first member at a position facing the second recess in the assembly direction.

4. The fluid flow path forming apparatus according to any one of claims 1 to 3, wherein each of the intersecting fluid flow paths has a pair of connection port sections (121a to 128a, 121b to 128b) for introducing or discharging fluid to or from an external device (VD, PD, SD), and an intermediate flow path section (121c to 128c) connecting the pair of connection port sections, and a portion of adjacent intermediate flow path sections is arranged to intersect in the assembly direction.

5. The flow path forming apparatus according to claim 4, wherein, of the pair of connection port portions in the second flow path, one portion facing the intersection forming portion opens to the other side in the assembly direction relative to the intersection forming portion.

6. The flow path forming apparatus according to claim 5, wherein the other of the pair of connection port portions in the second flow path is open to one side or the other side in the assembly direction.

7. One of the pair of connection port portions in the first flow path opens to one side or the other side in the assembly direction. The flow path forming apparatus according to claim 4, wherein the other of the pair of connection port portions in the first flow path is open to one side or the other side in the assembly direction.

8. The flow path forming apparatus according to claim 1, wherein the structure is formed by joining the first member and the second member by one of the joining elements: adhesion, welding, or baffling.

9. The flow channel forming apparatus according to claim 1, wherein the fluid flowing through the plurality of fluid channels is cooling water.
