Abstract

In a temperature regulation unit ( 10 ), a flow passage ( 50 ) for a fluid is formed between a plurality of rod-shaped members ( 30 ) which extend parallel to each other so as to be spaced apart from each other and are formed from porous metal; in the flow passage ( 50 ), the fluid flows along a flow direction which is a direction orthogonal to a direction in which the rod-shaped members ( 30 ) extend; and the flow passage ( 50 ) meanders along the flow direction.

Claims (23)

1 . A temperature regulation unit, wherein

a flow passage for a fluid formed between a plurality of rod-shaped members which extend parallel to each other so as to be spaced apart from each other, wherein the rod-shaped members are formed from porous metal, wherein

in the flow passage, the fluid flows along a flow direction orthogonal to a direction in which the rod-shaped members extend, and

the flow passage meanders along the flow direction, wherein, among the pluralities of rod-shaped members, rod-shaped members adjacent to each other in the flow direction are in contact so as to define respective side walls of the flow passage, the respective side walls extending in the flow direction, such that side boundaries of the flow passage are demarcated by the rod-shaped members.

2 . The temperature regulation unit according to claim 1 , wherein a cross-sectional shape of each of the rod-shaped members includes a tapered portion, and the tapered portions are disposed at both side walls of the flow passage.

3 . The temperature regulation unit according to claim 2 , wherein the cross-sectional shape of each of the rod-shaped members is a trapezoidal shape, a triangular shape, a semicircular shape, or a mountain shape.

4 . The temperature regulation unit according to claim 2 , wherein each of the rod-shaped members includes a curved surface.

5 . The temperature regulation unit according to claim 2 , wherein

in the flow passage, the respective rod-shaped members partially overlap each other when seen along the flow direction in the flow passage, and

the flow passage has a shape in which a virtual straight line extending parallel to the flow direction always hits the rod-shaped members.

6 . The temperature regulation unit according to claim 1 , wherein the cross-sectional shape of each of the rod-shaped members is a trapezoidal shape, a triangular shape, a semicircular shape, or a mountain shape.

7 . The temperature regulation unit according to claim 6 , wherein each of the rod-shaped members includes a curved surface.

8 . The temperature regulation unit according to claim 6 , wherein

in the flow passage, the respective rod-shaped members partially overlap each other when seen along the flow direction in the flow passage, and

the flow passage has a shape in which a virtual straight line extending parallel to the flow direction always hits the rod-shaped members.

9 . The temperature regulation unit according to claim 1 , wherein each of the rod-shaped members includes a curved surface.

10 . The temperature regulation unit according to claim 9 , wherein

in the flow passage, the respective rod-shaped members partially overlap each other when seen along the flow direction in the flow passage, and

the flow passage has a shape in which a virtual straight line extending parallel to the flow direction always hits the rod-shaped members.

11 . The temperature regulation unit according to claim 1 , wherein

in the flow passage, the respective rod-shaped members partially overlap each other when seen along the flow direction in the flow passage, and

the flow passage has a shape in which a virtual straight line extending parallel to the flow direction always hits the rod-shaped members.

12 . The temperature regulation unit according to claim 1 wherein each of the rod-shaped members is formed from metal fibers, metal powder, or a mixture of metal fibers and metal powder.
