[0002] A field medical refrigerator refers to a field refrigeration device suitable for field and emergency conditions, which can be used for fixed storage or for carrying with the army for medical supplies with special temperature requirements. Since the use scenarios of field medical refrigerators are mostly complex and critical environments, the stability of the refrigeration capacity of field medical refrigerators is very critical for their use. Current field medical refrigerators focus more on the design of the refrigeration area to ensure the function of the refrigeration part, but ignore the heat dissipation part of the refrigerator. The heat dissipation part of the refrigerator often only adopts a simple heat dissipation structure, but in actual use, due to the complexity of the environment or improper placement during use, the heat dissipation efficiency of the heat dissipation structure is low, which can easily lead to a series of adverse consequences, such as reduced refrigeration efficiency, refrigeration unit failure, etc. Based on the above problems, a new field medical refrigerator is urgently needed to solve the above problems.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In this embodiment, the main structure of the refrigerator is a box body 1 and a box cover 2. The box cover 2 can be opened or closed. The box cover 2 and the box body 1 can be locked by a lock when closed. A handle for easy lifting is provided on the side of the box body 1. Two cavities are provided inside the box body 1, one of which is a refrigeration cavity 3, which is used to place items to be refrigerated, and the other cavity is a cooling cavity 4, in which a cooling unit 5 is installed. The cooling unit 5 in this embodiment can be a circulating refrigeration device, a refrigeration system formed by components such as a compressor, a throttle valve, an evaporator and a condenser. The cooling end of the refrigeration unit 5 is close to the cooling cavity 3, which is used to reduce the temperature of the cooling cavity 3. The heat dissipation end of the refrigeration unit 5 is used to conduct the heat out of the refrigeration cavity 3. A fan can be installed in the refrigeration cavity 4. The fan accelerates the heat dissipation of the heat dissipation end. A removable end cover can be installed at the fan installation position for protection. The biggest difference from the prior art is that the three adjacent side walls of the refrigeration cavity 4 corresponding to the heat dissipation end of the refrigeration unit 5 are all provided with a heat dissipation grille area 6. The heat dissipation grille area 6 is on different side walls and faces different surfaces. Therefore, during use, no matter how complex the environment is or how unreasonable the placement is, the heat dissipation end of the refrigeration unit 5 always has a heat dissipation grille area 6 that can dissipate heat to ensure that it has sufficient heat dissipation efficiency, thereby avoiding heat dissipation obstruction and causing operation failures.

[0024] The heat dissipation grille area 6 is provided with a plurality of heat dissipation holes 7 , which are arranged axially tilted, and one end of the heat dissipation hole 7 located inside the box body 1 is higher than the other end located outside the box body 1 .

The heat dissipation holes 7 are circular holes in the present embodiment. The heat dissipation holes 7 are arranged in an inclined manner, and one end of the heat dissipation hole 7 on the inner side of the box body 1 is higher than the other end on the outer side of the box body 1. On the one hand, it can prevent external water from entering the interior through the heat dissipation hole 7, and also allow the water condensed at the heat dissipation hole 7 to flow to the outside of the box body 1.

[0026] The upper end surface of the box body 1 and the lower end surface of the box cover 2 are both provided with receiving grooves 8 and are arranged correspondingly.

Water droplets will be generated after opening the lid or defrosting. The water accumulated in the box can be smoothly discharged through the drain valve 9 to prevent the water in the box from freezing.

[0030] The refrigerator further includes a power socket 10 and a ground terminal 11 . The power socket 10 is arranged on the box body 1 , and the ground terminal 11 is connected to the box body 1 .

[0031] In this embodiment, a power socket 10 is also provided on the box body 1. The detachable power cord can make the use of the refrigerator more flexible, and a grounding terminal 11 is also provided on the box body 1.

[0032] The box body 1 is also provided with an operation panel 12 and a label frame 13 , and the operation panel 12 and the label frame 13 are located on the same side.

[0033] In this embodiment, an operation panel 12 and a label frame 13 are installed on one of the side surfaces of the box body 1. The operation panel 12 and the label frame 13 can be set at the same height. Labels can be placed in the label frame 13 to indicate operating precautions and save item information, so that personnel can set the operation panel 12 according to the situation.

[0034] The lower end surface of the box cover 2 is provided with a first sealing ring 14 and a second sealing ring 15, and the box body 1 is provided with an annular boss 16, which is arranged around the outlet of the refrigeration cavity 3, the second sealing ring 15 abuts against the annular boss 16, and the first sealing ring 14 abuts against the upper end surface of the box body 1.

[0035] In this embodiment, a closed space is formed between the box cover 2 and the refrigerated cavity 3 after being closed. In order to improve the sealing performance, a first sealing ring 14 and a second sealing ring 15 are provided on the lower end face of the box cover 2. The circumference of the second sealing ring 15 is smaller than that of the first sealing ring 14. The first sealing ring 14 is sleeved on the outer periphery of the second sealing ring 15. An annular boss 16 is provided on the upper end face of the box body 1 and the outer periphery of the outlet of the refrigerated cavity 3. The annular boss 16 abuts against the second sealing ring 15, and the first sealing ring 14 abuts against the upper end face of the box body 1. The double-ring seal improves the sealing performance.

[0036] The refrigerator further includes a storage basket 17 , and the storage basket 17 is detachably disposed in the refrigerating cavity 3 .
