PURPOSE:To unify the passing air speed distribution, improve the performance, and prevent dew scattering by providing multiple guide vanes distributing the air flow to the whole area of an evaporator at least on the air inflow side of the evaporator provided in the air passage of a case. CONSTITUTION:An evaporator 6 stored in the case 7 of a cooling unit 5 is provided with multiple guide vanes 14A, 14B on both air inflow and discharge sides. The angles of the guide vanes 14A, 14B are set so that the guide vanes 14A on the air inflow side uniformly distribute the air flow from an air inlet 12 to the whole area of the evaporator 6 and the guide vanes 14B on the air discharge side quickly guide the air flow passing through the evaporator 6 to an air outlet 13. The passing air speed distribution is unified. The guide vanes 14B on the air discharge side are not necessarily required to be provided. |
