Description

Technical Field

[0001] The invention relates to the technical field of semiconductor refrigeration chip detection, and in particular to an automatic detection device for semiconductor refrigeration chips. Background Art

[0002] Semiconductor refrigerator, also called thermoelectric refrigerator, is a heat pump. Its advantage is that it has no sliding parts. It is used in some places where space is limited, reliability is high, and there is no refrigerant pollution. It mainly uses the Peltier effect of semiconductor materials. When direct current passes through a couple made of two different semiconductor materials in series, heat can be absorbed and released at both ends of the couple, thereby achieving the purpose of cooling. It is a refrigeration technology that produces negative thermal resistance. It is characterized by no moving parts and relatively high reliability. The temperature difference between the hot and cold surfaces of the semiconductor refrigerator can be controlled by adjusting the current and voltage. By adjusting the input current and voltage, the temperature difference and cooling capacity of the refrigerator can be changed to meet different cooling needs. The wires on the refrigerator are used to connect to the power supply, so the tightness of the connection determines whether the refrigerator can be used normally. In order to ensure the quality of the refrigerator, the tightness of the connection between the refrigerator and the guide needs to be tested.

[0003] The traditional detection method is to fix the cooling plate, vibrate it for a period of time, then connect the power to the wire, and then measure the temperature of the hot and cold surfaces of the cooling plate through a temperature display. However, this method cannot detect the status of the hot and cold surfaces of the cooling plate in real time, so it is impossible to discover the problem of the connection between the cooling plate and the wire in time.
