Efficient cold air cycle air curtain system of display cabinet

Abstract

The invention discloses an efficient cold air cycle air curtain system of a display cabinet. The efficient cold air cycle air curtain system comprises a cabinet body and a cold air cycle air curtain circulation device arranged on the cabinet body, wherein an air outlet is provided with at least one inner cold air cycle air curtain forming mechanism, an inner cold air cycle air curtain used for shunting a part of airflow and forming the airflow with the diminishing air speed from inside to outside after blowing through the air outlet, at least one outer cold air cycle air curtain forming mechanism, and an outer cold air cycle air curtain used for shunting a part of airflow and forming the airflow with the diminishing air speed from inside to outside after blowing through the air outlet, and the inner cold air cycle air curtain forming mechanism is close to the outer cold air cycle air curtain forming mechanism. According to the invention, the efficient cold air cycle air curtain system is simple in structure, so that the air curtain reaches a best vertical shunt state, thus the refrigeration effect of the cold air is improved, and the energy-saving and cost-reducing effects can be realized.

Description

Technical field: [0001] The invention relates to the technical field of commercial freezing / refrigerating display cabinets, in particular to a high-efficiency cold air circulation air curtain system for a display cabinet. Background technique: [0002] The cold air circulation air curtain system of the refrigerated display cabinets used in traditional supermarkets or convenience stores only uses simple air outlets and return air outlets to form a cold air circulation. For example, the Chinese patent No. is "ZL200620072511.5" and the patent name is "drink display cabinet". The air outlet simply sends cold wind to the glass screen to form a cold air circulation. There is also a Chinese invention patent with the Chinese patent number "ZL00214891.9" and the patent name "Cold Air Circulation Air Curtain Adjustable Display Cabinet". Cool air circulates. [0003] In addition, the Chinese invention patent with the Chinese patent number "201020535491.7" and the patent name "horizon...

[0003] In addition, the Chinese invention patent with the Chinese patent number "201020535491.7" and the patent name "horizontal refrigerated display cabinet with glass sliding door" and the Chinese invention patent with the Chinese patent number "201120268115.0" and the patent name "A The Chinese invention patent of "flat-horizontal display cabinet", which is provided with a turning part or a windshield at the turning inside the air duct. This design is to change the flow direction of the wind at the turning or corner in the air duct. The wind changes direction at the turning point or corner in the air duct and then blows out from the air outlet uniformly. Although the wind blown out of the air outlet generally flows in the same direction, the air outlet has a greater impact on the wind blown out from the air outlet. The control of speed and direction is very limited, and the air flow blown out from the air outlet to form the cold air circulation air curtain is actually in a turbulent state

This traditional cold air circulation air curtain circulation is likely to cause leakage of cooling capacity in the cabinet and entry of external heat, resulting in uneven temperature distribution in the cabinet or increased energy consumption, so it is necessary to improve it
