Title:
REACTOR UNIT
Document Type and Number:
Japanese Patent JP2019110208
Kind Code:
A
Abstract:
To suppress a thermal boundary layer which may be formed at the inside of a lateral face to which reactors 2 are attached, in a reactor unit 100 where the multiple reactors 2 are attached to a cooler 10 side by side.SOLUTION: A reactor unit 100 includes multiple reactors 2 and a cooler 10. An inside of the cooler 10 is a duct 13 of cooling medium, and the multiple reactors 2 are attached to an external surface of a bottom plate 14 separating the duct and the outside. Multiple fins 31 are provided on a duct side surface of the bottom plate 14. Flat parts 21, 22 where the fins are not erected are provided in a first region corresponding to a cavity between a pair of coils 3a, 3b of each reactor 2, on the duct side surface of the bottom plate 14, and a second region adjoining the four corners of the reactors 2, respectively, in a plan view of the bottom plate 14. Since refrigerant flow produces turbulence in the flat parts 21, 22, the thermal boundary layer is suppressed.SELECTED DRAWING: Figure 7
