Since the air is sent below the rails, the wind speed distribution in the chamber J becomes faster on both sides as shown in Figure 6, and the circulation amount (feeding amount) of the cooling air sent to the floor rails becomes uneven. If there is a problem that the object to be cooled cannot be cooled uniformly, and if the air temperature of the cooling air cooled by the evaporator E is different on the left and right sides, these airs are mixed on the exit side of the evaporator E. The air passage immediately divides into left and right without
The chamber J as described above via H 1 and H 2
Since the cooling air flows from the cooling air to the floor rails, there is little mixing before reaching the floor rails, and there is also a problem that the temperature distribution of the cooling air sent to the floor rails becomes uneven.

均一に行えるのである。(Effect of the invention) The present invention makes the upper surface of the partition wall 14 facing the air outlet side of the evaporator 4 provided in the cooling chamber 10 slope downward from both sides in the width direction toward the center, and First air passages 21, 2 on the sides
2, and a second air passage 23 is formed at the rear thereof, and the cooling air is delivered from the blowing chamber 20 to the bottom of the freezer A, that is, the floor rail b, through these air passages 21, 22, and 23. Therefore, the wind speed distribution of the cooling air passing through the first air passages 21 and 22 in the blowout chamber 20 is such that the wind speed is highest on both sides of the blowout chamber 20 in the width direction, and the wind speed is highest in the central portion. In addition, the wind speed distribution of the cooling air passing through the second air passage 23 is changed by tilting the upper surface of the partition wall 14 downward from both sides in the width direction toward the center, so that the cooling air exits the evaporator 4. After the cooling air collides with the upper surface of the partition wall 14, it becomes easier to flow toward the center along the upper surface, and the wind speed becomes the highest in the center of the blowout chamber 20,
At both sides in the width direction, the wind speed is the slowest, and by merging the cooling air flowing through the first air passages 21, 22 and the second air passage 23, the wind speed distribution in the blowout chamber 20 is almost uniform throughout. This makes it possible to uniformly circulate the amount of cooling air sent from the chamber 20 to the floor rails, and to uniformly cool the objects to be cooled in the freezer A.

Even if the temperature distribution is uneven at the outlet of the evaporator 4, the overall temperature distribution in the blowout chamber 20 becomes uniform, and the temperature distribution in the freezer A becomes uniform. It is also possible to improve the averaging of temperature distribution.
