Description

Technical Field

[0001] The present invention relates to the technical field of medical refrigeration equipment, and in particular to a refrigeration unit assembly. Background Art

[0002] Medical refrigeration equipment used to store biological samples, pharmaceuticals, vaccines, and other items typically utilizes a finned evaporator housed within a cabinet, along with a fan. Specifically, the evaporator and fan are located within an air duct within the refrigeration equipment. The fan circulates air through the evaporator, cooling the air passing through the evaporator. The cooled air then flows out of the air outlet and into every corner of the cabinet, cooling the entire interior of the refrigeration equipment.

[0003] Refrigeration equipment typically uses internal temperature sensors to monitor and control the temperature within the cabinet. These internal temperature sensors are typically located at a certain distance from the air outlet. Therefore, the temperature they monitor is higher than the air outlet temperature. Even when the internal temperature meets the required temperature, the air outlet temperature may already be lower than the required temperature. Existing refrigeration units for medical refrigeration equipment primarily include a bottom radiator, a top radiator for dissipating heat from a cooling end located above the bottom radiator, a drain pipe for discharging condensed water from the bottom and top radiators, and a cooling fan for blowing air to dissipate heat from the cooling end of the top radiator. However, this technology presents the following problems: 1. The air duct, formed by the structure of the bottom radiator in this application, is too narrow, hindering the discharge of hot air and, in turn, affecting the cooling effect. 2. Only one drain pipe is provided for condensed water drainage, resulting in slow drainage and accumulation of condensed water, which in turn affects the cooling effect. 3. The fins of the bottom radiator are manufactured using a splined design, which disconnects the fins from the heat dissipation surface, resulting in poor heat conduction and, in turn, poor cooling effect. In light of these issues, we propose a refrigeration unit assembly. Summary of the Invention
