Abstract
PURPOSE: To improve the performance of an open showcase, by providing a rectifier which is located at an air blow-off port of the showcase and has adjacent air passages and by non-rectilinearly varying the length of the air passages in the front- to-rear direction of the showcase.
CONSTITUTION: An air passage 2 is defined on the inside surface of a heat-insulating casing 1. A cooler 3 and a blower 4 are provided in the air passage 2. Air sucked through a suction port 5 located in the lower part of the showcase is blown off through a blow-off port 6 of the upper part of the showcase and the rectifier 7 while the air is cooled. Thereby, an air curtain 8 is made between the inside and outside of the showcase. The rectifier 7 has numerous adjacent slender air passages of hexagonal cross section like a honey-comb. The upstream end face of the rectifier is so curved that the length of the air passages is non-rectilinearly varied in the front-to-rear direction of the showcase. As a result, the initial velocity vo of the blown-off air is non-rectilinearly varied in the front-to-rear direction of the showcase. Thereby, the performance of the showcase is improved.
