The size and number of the cold plate 11 and the fixing holes 17 can be adjusted according to needs and actual conditions. The semiconductor refrigeration plate 11 is electrically connected to the PLC controller. A first radiator 10 is fixedly installed on one side of the interior of the cooling chamber 3, and thermal grease is filled between the first radiator 10 and the semiconductor refrigeration plate 11. A second radiator 12 is fixedly installed on one side of the interior of the cooling chamber 3, and thermal grease is filled between the second radiator 12 and the semiconductor refrigeration plate 11. A first connecting hole 14 is opened on one side of the interior of the cooling chamber 3, and a plurality of air outlet holes 15 are opened on one side of the cooling chamber 3. A fixing plate 18 is fixedly sleeved on the interior of the cooling chamber 3, and a first circular through hole is opened on one side of the fixing plate 18.

[0025] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: when the cabinet 1 is in use, the first temperature detector 19 is provided, and the first temperature detector 19 detects the internal temperature of the cabinet 1. When the temperature is detected to be below 30 degrees Celsius and above 10 degrees Celsius, the first cooling fan 5 is provided, and the first cooling fan 5 is started to blow air into the inner bottom of the cooling bin 3 through the air inlet 4. At the same time, the driving mechanism 8 is started to drive the semicircular plate 9 to rotate, so that the semicircular plate 9 rotates to cover the right half of the air inlet hole 6, so that the flowing air enters the left space of the partition 7 through the left half of the air inlet hole 6 and is ejected through the plurality of air outlet holes 15 provided, thereby cooling the cabinet. The interior of the cabinet 1 is cooled, and then the hot air is discharged from the interior of the cabinet 1 through the one-way exhaust valve 20. However, when the weather is hot and the workload is high, the first temperature detector 19 and the second temperature detector 22 detect that the internal temperature of the cabinet 1 exceeds 30 degrees Celsius, and the air outside the cabinet 1 also exceeds 30 degrees Celsius. The air introduced from the outside is difficult to meet the heat dissipation demand. At this time, the driving mechanism 8 is started to drive the semicircular plate 9 to cover the left half of the air inlet 6, and then the air flow blown into the cooling chamber 3 by the first cooling fan 5 enters the right space of the partition 7 through the right half of the air inlet 6. At the same time, the semiconductor refrigeration is set The semiconductor refrigeration sheet 11 is started to work. The side of the semiconductor refrigeration sheet 11 close to the first radiator 10 is a heating surface, and then the heat is absorbed by the first radiator 10, and the flowing air dissipates the heat of the first radiator 10, and the hot air is discharged from the interior of the cabinet 1 through the exhaust port 16, and then the other side of the semiconductor refrigeration sheet 11 is a cooling surface, and the cooling is conducted through the second radiator 12. At the same time, the second cooling fan 13 is started to blow air into the cooling chamber 3, and the second radiator 12 cools the flowing air, and the side of the second radiator 12 is ventilated through the second connecting hole 25, so as to increase the contact surface between the second radiator 12 and the air, so as to reduce the temperature of the flowing air. The cooling effect is better, the cooled air enters the other side of the cooling chamber 3 through the first connecting hole 14, and is then ejected through a number of air outlet holes 15, forming a complete internal circulation, thereby cooling the interior of the cabinet 1, thereby comprehensively achieving the effect of cooling the interior of the cabinet 1 and delaying the aging of the internal electrical appliances. Through the use of the first temperature detector 19 and the second temperature detector 22, when the external temperature of the cabinet 1 is low for a long time, the external air can be directly sent into the interior of the cabinet 1. When the internal and external temperatures are both over 30 degrees, the semiconductor refrigeration sheet 11 is used for cooling, and the interior of the cabinet 1 is cooled by internal circulation, thereby ensuring the cooling effect, utilizing both natural cooling and machine cooling, which is more practical.
