Technical Field

[0001] This application relates to the technical field of semiconductor thermoelectric modules, and specifically proposes a semiconductor thermoelectric module manufacturing apparatus. Background Technology

[0002] A semiconductor thermoelectric module is a system that operates based on the thermoelectric effect. It mainly consists of a thermoelectric chip, a cold-end heat exchanger, a hot-end heat exchanger, and connecting components. This system can achieve thermoelectric conversion, meaning it can directly convert electrical energy into a temperature difference for cooling or heating, or conversely, convert the temperature difference into electrical energy for power generation.

[0003] In actual production, the integration of semiconductor thermoelectric modules generally involves mechanically pressing the two sides of the thermoelectric chip together with the cold-end heat exchanger and the hot-end heat exchanger to form a highly efficient energy conversion system.

[0004] However, the core materials in thermoelectric chips (such as bismuth telluride) are sensitive to mechanical stress. Specifically, they have strong compressive strength in the axial direction but poor shear strength in the radial direction. When the applied pressure is deflected relative to the thermoelectric chip, the core material is prone to cracking. This not only increases thermal resistance and reduces cooling performance, but may also affect the operational stability and lifespan of the thermoelectric chip. Summary of the Invention

[0033] In the present embodiment, the pressing assembly 220 has a pressing surface 2024, the driving member 210 can drive the pressing assembly 220 to approach the support 10, so that the pressing surface 2024 presses the first surface of the semiconductor thermoelectric module; the pressing surface 2024 is deflectably arranged relative to the horizontal plane, so that the pressing surface 2024 is in close contact with the first surface.

The connector 221 is connected to the power output part 211 of the drive member 210. The pressing structure 222 is rotatably disposed on the connector 221 relative to the connector 221, thereby realizing the deflection adjustment of the pressing surface 2024. It can be regarded as a coarse adjustment of the deflection angle, thereby controlling the angular distribution of the pressing force.

[0037] In some embodiments, refer to Figure 2 and Figure 3 The pressing component 220 also includes a shaft 223, which is located between the connector 221 and the pressing structure 222. The pressing structure 222 can deflect relative to the connector 221 around the shaft 223.
