| (54) | COOLER AND YARN PROCESSOR |
| (57) Efficiency in cooling of a yarn is improved in a cooler that is configured to cool
the yarn by cooling wind. A cooler 14 includes a cooling unit 31 in which a yarn running
space S in which a yarn Y runs is formed and an intake duct 32 in which an intake
space Ss connected to the yarn running space S is formed. The intake duct 32 includes
a duct wall portion 34 in which one or more intake slit 38 is provided to extend in
a unit longitudinal direction between the yarn running space S and the intake space
Ss in a flow direction in which cooling wind flows. The cooling unit 31 includes paired
unit wall plates 51 that are provided on one side of the duct wall portion 34 in the
height direction. The paired unit wall plates 51 includes paired unit wall surfaces
55 which oppose each other in the width direction over the yarn running space S. The
height in the height direction of each of the paired unit wall surfaces 55 is 30 mm
or less.
