Microchannel structure and manufacturing method therefor, light source device, and projector

1. A microchannel structure comprising:

plural microchannels through which fluid flows, the microchannels having a housing section formed in a block; and

a pipe array arranged in each housing section and formed by stacking plural pipes, each pipe having a surface, the surface of each of the pipes being in contact with the surface of an adjacent pipe,

wherein the fluid is fed to an inside of the pipes and spaces among the pipes.

2. The microchannel structure according to claim 1 , wherein a sectional shape of the housing section orthogonal to a flowing direction of the fluid is gradually narrowed toward a bottom of the microchannels.

3. The microchannel structure according to claim 1 , wherein a part of a surface of the pipe array is formed as a mounting area for a solid light-emitting light source that generates heat and emits light.

4. The microchannel structure according to claim 3 , wherein the mounting area for the pipe array is planarized.

5. The micro channel structure according to claim 3 , further comprising a fixing section in which an opening corresponding to the mounting area is formed and that is fixed to the block to fix the pipe array.

6. The microchannel structure according to claim 1 , further comprising a mounting plate, one surface side of which is formed as a mounting area for a solid light-emitting light source that generates heat and emits light and the other surface side of which is made capable of coming into close contact with the pipe array.

7. The microchannel structure according to claim 1 , wherein the plural pipes are in surface contact with one another.

8. The microchannel structure according to claim 7 , wherein a sectional shape of the pipes is a polygonal shape.

9. The microchannel structure according to claim 1 , wherein a sealing material having thermal conductivity higher than thermal conductivity of the fluid is filled among the pipes.

10. The microchannel structure according to claim 1 , wherein thin pipes having a diameter smaller than that of the pipes or bar members having a diameter smaller than that of the pipes are set among the pipes.

11. The microchannel structure according to claim 1 , wherein plural through-holes are formed in the pipes.

12. The microchannel structure according to claim 11 , wherein the through-holes are formed in the pipes other than the pipes at the uppermost stage in the housing section.

13. A light source device comprising:

a solid light-emitting light source that emits light and generates heat when an electric current is supplied thereto; and

a base on which the solid light-emitting light source is mounted,

wherein the microchannel structure according to claim 1 is used as the base.
