Description

Technical Field

[0001] This utility model relates to the technical field of air-cooled refrigeration equipment, specifically to an air-cooled ultra-low temperature freezer storage box. Background Technology

[0002] Generally, ultra-low temperature freezer evaporators use pipes attached to the inner liner to achieve cooling through natural convection of cold air. During use, this can cause frost formation on stored items and uneven temperature distribution inside the freezer, causing inconvenience to customers. In contrast, air-cooled low temperature freezers typically have heating wires or heating pipes on the evaporator, which are turned on during defrosting. This can raise the temperature inside the freezer to around 40 degrees Celsius, affecting the safety of stored items.

[0003] Therefore, considering the need to solve the problems of icing and uneven temperature inside the refrigeration equipment box, as well as the problem of the temperature inside the box rising and affecting the ambient temperature inside the box; in view of this, we propose an air-cooled ultra-low temperature freezer storage box.

[0026] Please see Figure 1-3 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] Air-cooled ultra-low temperature freezer, such as Figure 1 and Figure 2 The structure shown includes an evaporator 2, an evaporating fan 3, and a heater 4 installed at the top of the chamber. In this embodiment, the evaporator 2 is a finned evaporator, eliminating the need for a pipe-mounted evaporator and solving the problems of icing and uneven temperature inside the chamber. A sealing body 1 is installed at the top of the chamber to separate the evaporator 2, the evaporating fan 3, and the heater 4. This sealing body 1 has a conductive structure for air circulation. It also includes:

[0028] Air duct 5 is equipped with ventilation holes that communicate with the interior of the enclosure;

[0029] Cold storage components, such as Figure 1 Installation location, including the cold storage rack 6 installed inside the enclosure, specifically, as follows: Figure 3 As shown in the structure, a cold storage unit 7 is detachably installed on the cold storage rack 6. In this embodiment, a fixing plate 9 is detachably installed on the cold storage rack 6. The fixing plate 9 is used to press the cold storage unit 7 onto the cold storage rack 6. The fixing plate 9 can keep the cold storage unit 7 fixed and prevent it from shaking during transportation.

[0030] The cold storage rack 6 in this embodiment is provided with mounting holes 64, which are detachably mounted on the housing by connecting bolts 8. The cold storage rack 6 is also provided with air inlets for air circulation. The air inlets include a first air inlet 61, a second air inlet 62, and a third air inlet 63 arranged around the cold storage 7. When the evaporator fan 3 is started, it generates air circulation that flows through the air inlets, the cold storage 7, the evaporator 2, and the air duct 5. When the heater 4 is needed, it can make the hot air pass through the cold storage 7 during the air circulation. The cold storage 7 can offset the heat generated during defrosting, thereby solving the problem of temperature rise inside the housing during defrosting. In this embodiment, the cold storage 7 uses a low-temperature ice crystal box as the cold storage device. In other embodiments, a cold storage plate filled with cold storage agent can also be used as the cold storage 7.
