Problems solved by technology

[0005] However, in the thermoelectric module described in Patent Document 1, since the temperature detection element is provided on the inner surface of the first support substrate, when a temperature change occurs in the first support substrate, the temperature change can be quickly detected. However, when the temperature of the second support substrate changes, since the heat of the second support substrate is transmitted to the temperature detection element via the pyroelectric element and the first support substrate, it takes a long time to detect the temperature change.
As a result, when the thermoelectric module is used for temperature regulation, it may take a long time for the temperature regulation
In addition, when a thermoelectric module is used for thermoelectric power generation, since it takes a long time to adjust the heat transferred to the thermoelectric module, the power generation efficiency of the thermoelectric module may decrease.

Abstract

This thermoelectric module comprises: a first support substrate comprising a main surface that has a first region and a second region adjacent to the first region; a second support substrate provided such that the main surface thereof faces the first region; a plurality of thermoelectric elements arrayed between the first region and the main surface of the second support substrate; and a temperature detection element mounted on the second region. The temperature detection element and the second support substrate are thermally connected via a thermally conductive member.

Description

technical field [0001] The present invention relates to a thermoelectric module used for thermoelectric power generation such as thermoelectric power generation such as temperature regulation of thermostatic baths, refrigerators, automotive seat coolers, semiconductor manufacturing equipment, laser diodes, and fuel cells. Background technique [0002] As a thermoelectric module, for example, a thermoelectric module described in Japanese Patent Laid-Open No. 2007-294864 (hereinafter referred to as Patent Document 1) is known. The thermoelectric module described in Patent Document 1 includes a first support substrate, a second support substrate facing the first support substrate, and a plurality of thermoelectric elements provided between the first support substrate and the second support substrate. [0003] A thermoelectric module can generate a temperature difference between one support substrate and the other support substrate by applying a voltage to a plurality of thermoe...
