Technical Field

[0001] This utility model relates to the technical field of louver adjustment devices, and in particular to a louver adjustment device for a cold storage fan. Background Technology

[0002] Cold storage is mainly used as a constant temperature storage and refrigeration equipment for food, dairy products, meat, aquatic products, chemicals, pharmaceuticals, seedlings, scientific experiments, etc. Cold storage is actually a type of low temperature cold storage and belongs to the category of refrigeration equipment. Compared with refrigerators, its refrigeration area is much larger, but they have the same refrigeration principle.

[0003] Utility model CN210179977U relates to the technical field of cold storage air coolers, specifically an adjustable airflow cold storage air cooler. It includes a body and a fan rotatably connected to the body. The body has an air-adjusting device covering the fan. The air-adjusting device includes an air-adjusting frame mounted on the side wall of the body and several louvers rotatably connected to the air-adjusting frame along its length. Each louver has a rotating shaft rotatably connected to the air-adjusting frame at both ends. The air-adjusting frame has a drive structure for simultaneously rotating the several rotating shafts. This utility model has the following advantages: by driving the several louvers to rotate simultaneously, the surface of the louvers forms an angle with the rotation center line of the fan. This causes the cold air blown from the fan to change direction as it passes through the louvers, thereby cooling a specific direction in the cold storage and improving the cooling effect.

[0004] Existing cold storage fan louver adjustment devices rely on manual adjustment, which lacks precision and makes it difficult to accurately control the airflow direction of the cold storage fan. Therefore, this invention proposes a cold storage fan louver adjustment device to solve the above problems. Utility Model Content
