Thermoelectric module and manufacturing method thereof

Abstract

The invention discloses a thermoelectric module and a manufacturing method thereof. The thermoelectric module comprises a lower thermoelectric module, wherein p type and n type semiconductor elements are arranged on the upper part of the lower insulation substrate along the horizontal direction; an upper thermoelectric module, wherein p type and n type semiconductor elements, which are electrically connected, are arranged on the lower part of the upper insulation substrate along the horizontal direction; and a joint part, which joins the p type semiconductor element in the upper thermoelectric module and the p type semiconductor element in the lower thermoelectric module and also joins the n type semiconductor element in the upper thermoelectric module and the n type semiconductor element in the lower thermoelectric module. Through the joint part, the upper part thermoelectric module comprising a thermoelectric semiconductor element and the lower part thermoelectric module comprising a thermoelectric semiconductor element are joined together, thus the thickness of thermoelectric semiconductor element part is multiplied by two; so the temperature difference between two ends of the thermoelectric semiconductor element part is increased, the electro-dynamic potential of the thermoelectric module is increased, and when the thermoelectric module is used as a temperature sensor, the sensitivity of the sensor is improved.

Description

technical field [0001] The invention relates to a thermoelectric module and a manufacturing method thereof. Background technique [0002] Temperature sensors are essential components for monitoring the temperature of household appliances such as ovens and refrigerators. In addition, in industrial equipment, monitoring such as accurate temperature maintenance and adjustment can also be said to be a necessary condition for the production of high value-added products. Therefore, it can be said that a temperature sensor for monitoring temperature is a necessity in almost all fields including daily life and industrial fields. There are various types of temperature sensors currently on sale depending on the temperature range and resolution to be measured. [0003] Thermoelectric phenomena can be divided into two major technologies, which are classified into cooling technology using the Peltier effect and energy harvesting technology using the Seebeck effect. Both types can be sa...

Problems solved by technology

However, when the semiconductor element is formed in a thin film form, the temperature between the heat absorption side and the heat dissipation side is balanced in a short time due to the thin thickness in terms of process characteristics, so that the temperature between the heat absorption side and the heat dissipation side is balanced. The temperature difference between

As such, the thin-film type thermoelectric module has the disadvantage that the thickness of the thin film that can be formed is limited, so that the temperature difference between the heat-absorbing side and the heat-radiating side is not significant, and thus the thermoelectromotive force cannot be increased, resulting in a decrease in temperature sensing performance
