Medical refrigerating box air duct and medical refrigerating box

Abstract

The invention discloses a medical refrigerating box air duct. The medical refrigerating box air duct comprises a top air duct and a rear air duct. An air inlet is formed in the top air duct, and a refrigeration fan is arranged at the position, corresponding to the air inlet, in the top air duct. An evaporator is arranged at the position, at the rear end of the refrigeration fan, in the top air duct. The rear air duct comprises a stirring air duct and a circulating air duct positioned around the stirring air duct; the upper portion of the circulating air duct communicates with the top air duct; multiple air outlets are formed around the front side of the circulating air duct; a stirring air inlet is formed in the middle of the front side of the stirring air duct, and a stirring fan is arranged at the position, corresponding to the stirring air inlet, in the stirring air duct; and multiple stirring air outlets are formed around the front side of the stirring air duct. The invention further discloses a medical refrigerating box. The refrigeration fan in the medical refrigerating box air duct is used for circulating air in the box, so that the air is refrigerated and cooled through the evaporator; and the stirring fan is used for enabling the air in the box to form turbulent flow, so that the air in the box is fully mixed and stirred, the temperature in the box is more uniform, and the phenomenon of temperature stratification is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical refrigerators, and in particular relates to an air duct of a medical refrigerator and a medical refrigerator. Background technique [0002] In the medical industry, medical refrigerators at 2°C to 8°C are widely used, and are generally suitable for hospitals, blood banks, epidemic prevention stations, scientific research institutes, disease control centers, pharmacies and other industry institutions to store vaccines, drugs, reagents, blood and other medical supplies. Multi-scenario and multi-frequency applications have greatly increased the demand for medical refrigerators, and at the same time put forward higher requirements for the performance of medical refrigerators. [0003] At present, the structure type of the air duct in the medical refrigerator on the market is relatively single, and most of them use a single set of cooling fans to operate to realize the traditional structure type of on...

Problems solved by technology

[0003] At present, the structure type of the air duct in the medical refrigerator on the market is relatively single, and most of them use a single set of cooling fans to operate to realize the traditional structure type of one-way circulation of the air in the box. After being cooled by the evaporator, it is blown into the box from the air outlet, and the cold air blown out of the air outlet takes away the heat in the box and is sucked into the air duct again, so as to achieve the purpose of cooling and air circulation in the box; The air duct structure with single wind direction circulation can achieve the purpose of cooling inside the box, but there is a large difference in air temperature in the box near the air outlet and the air inlet, and the influence of the temperature difference of the air outlet at different positions will increase the temperature of the box. The temperature difference inside the box will easily lead to the deterioration of the uniformity of the temperature in the box, and even the phenomenon of temperature stratification in the box
