[0067] Refrigeration device 9 The thermoelectric effect of pure metal is very small. If an N-type semiconductor and a P-type semiconductor are used instead of metal, the effect will be much greater. The figure shows the working principle of semiconductor refrigeration. After the power is turned on, electron-hole pairs are generated near the upper contact, the internal energy decreases, the temperature decreases, and heat is absorbed to the outside world, which is called the cold end. The other end increases the internal energy and temperature due to the recombination of electron-hole pairs, and releases heat to the environment, which is called the hot end.

[0068] The temperature difference and cooling capacity generated by a pair of semiconductor thermoelectric elements are very small. Practical semiconductor refrigerators are composed of many pairs of thermoelectric elements connected in parallel and series, also known as thermopiles. A single-stage thermopile can obtain a temperature difference of about 60°C, that is, the cold end temperature can reach -10 to -20°C. Increasing the number of thermopiles can increase the temperature difference between the two ends.

After the other placement seat 33 is rotated to one side of the movable plate 2, the remaining asphalt concrete can be installed in the fixed ring 34 inside the placement seat 33.

[0071] After the asphalt concrete is installed, the hydraulic rod 41 is started again to drive the connecting frame 42 to move downwardly toward the movable plate 2. When the connecting frame 42 moves downwardly toward the movable plate 2, it drives the multiple sealing covers 43 on the surface to move toward one side of the placement seat 33. When the sealing cover 43 moves to the inside of the sealing groove 35 opened on the surface of the placement seat 33, it is lifted to the work of the hydraulic rod 41. At the same time, the threaded sleeve 73 at one end of the connecting rod 71 is threadedly connected with the threaded block 123 on the surface of the mounting frame 122 at the bottom of the hydraulic telescopic rod 121.

When the threaded sleeve 73 with the connecting rod 71 is threadedly connected with the threaded block 123, the hydraulic telescopic rod 121 is started to drive the mounting bracket 122 to move downward. When the mounting bracket 122 moves downward, it pushes the connecting rod 71 that drives the extrusion block 72 to move toward the temporal part of the sealing cover 43. When the extrusion block 72 moves toward the inside of the sealing cover 43, the asphalt concrete on the surface of the placement seat 32 is extruded. Test.
