The function of the cold-transfer metal block 402 is: the cold energy released in the semiconductor chip 6 is physically conducted to the whole cold-conducting metal piece 4, so that the circulating airflow is cooled through the vertical air-cooling gap of the cold-conducting metal piece 4. Because the semiconductor chip 6 is too thin, one end releases heat to generate a large amount of heat, and the other end absorbs heat to generate a large amount of cold, the cold transfer metal block 402 can also play a role in properly separating the cold transfer metal piece 4 from the semiconductor chip 6, and the influence of the heat generated by the heat release of the semiconductor chip 6 on the cold transfer airflow is avoided.
Preferably, the material of the cold-transfer metal piece 4 is aluminum, and the cold-transfer metal piece is of an integral casting structure. The structure can ensure that no installation gap exists between each part of the cold transmission metal piece 4, and can effectively improve the cold transmission efficiency.
