THERMOELECTRIC COOLER, MANUFACTURING METHOD FOR THERMOELECTRIC COOLER, AND ELECTRONIC DEVICE

摘要

A thermoelectric cooler, a manufacturing method for the thermoelectric cooler, and an electronic device. The thermoelectric cooler comprises two single-crystal silicon substrates (1) opposite to each other, and multiple semiconductor thermoelectric particles (3) located between the two single-crystal silicon substrates (1); the sides of the single-crystal silicon substrates (1) towards the semiconductor thermoelectric particles (3) are each provided with an insulating layer (4); conductive sheets (2) are provided between the insulating layers (4) and the semiconductor thermoelectric particles (3); the conductive sheets (2) are electrically connected to the semiconductor thermoelectric particles (3) so that the semiconductor thermoelectric particles (3) form a series connection circuit. Because the semiconductor thermoelectric particles (3) have a thermoelectric effect, the two single-crystal silicon substrates (1) of the thermoelectric cooler can be used for cooling and heating respectively. The single-crystal silicon substrates (1) are used as substrates of the thermoelectric cooler, the single-crystal silicon substrates (1) are low in cost, and thus, the thermoelectric cooler is low in cost.
