膨張弁の弁開度を得るようにしている。(C) Problems to be Solved by the Invention In general, an open-side case is constructed by making the length of the cooler housed in the cold air circulation duct shorter than the length of the insulating wall constituting the main body. A space for adjusting the expansion valve is formed between the left and right side surfaces of the cooler. That is, a plate-fin type cooler is usually used as the cooler, and an expansion valve that supplies reduced-pressure refrigerant to the cooler is placed in the space on one side of the cooler. The valve opening of the expansion valve is adapted to the ambient conditions of the case.

問題点があつた。 By the way, in the above-mentioned conventional technology, the non-uniformity of the air volume distribution caused by the rotating direction of the blower fan, that is, the strength and weakness of the dynamic pressure, can be corrected by using the partition plate, but the cold air whose temperature has decreased after passing through the cooler and the cooling In other words, the air that has passed through the space (lower temperature than the outside air) mixes with the air that does not pass through the space before reaching the blower fan, so the cold air flowing through the ceiling air duct undergoes heat exchange with the cooler. There was a problem in that the temperature was higher than that of the cold air immediately after cooling, and it took a long time from the start of the cooling operation until the temperature in the product storage chamber was lowered to a predetermined temperature.

すことができる。 Therefore, according to such a configuration, the cover plates 30, 30 function to prevent the passage of cold air on the outside of both left and right side surfaces of the cooler 8, and this function prevents the cold air flow sent from the fans 10, 10. Everything can be heat exchanged with the cooler 8, and the full plate 3
1 and 31 act to increase the pressure of the cold air flow that has passed through the cooler 8, and direct a portion of this cold air flow directly above the cover plates 30 and 30, that is, in the direction of both left and right sides of the first passage 11. Through these two actions, it is possible to equalize the wind speed and temperature distribution of the cold air flow in the passage 11 which is on the leeward side of the full plates 31, 31, and furthermore, the cold air that has been heat exchanged in the cooler 8 can be Among the airflow, the cold airflow passes through the gap between the first partition plate 4, which forms the back wall of the storage chamber 7, and the front ends of the buffle plates 31, 31, and the cold airflow passes through the gap between the front ends of the buffle plates 31, 31 and the side covers 28, 28. Since the cold air flowing through the gap between the two flows in a connected state, that is, without being separated, it is possible to eliminate imbalance in the dynamic pressure of the fans 10, 10 on the leeward side of the full plates 31, 31. .
