Abstract

The invention discloses a laminated film type thermoelectric device and a preparation method thereof. The invention belongs to the preparation technology field of the thermoelectric device, to be specific, relates to the laminated film type thermoelectric device and the preparation method thereof. The object of the invention is to solve the problems of the preparation method of the conventional thermoelectric devices that curved surface attaching and scale production high efficiency preparation are hard to realize. The laminated film type thermoelectric device sequentially comprises a substrate, a bottom insulation layer, a plurality of thermoelectric module groups, a plurality of temporary supporting object filling areas, and a top part insulation layer. The thermoelectric module group sequentially comprises a bottom part conductive layer, a P type thermoelectric module, an N type thermoelectric module, and a top part conductive layer. The method is characterized in that by using a mask, various coatings are sprayed by adopting an atmosphere plasma spraying technology. According to the invention, the product structure is simple, and the method is effective and flexible, and therefore the firm attaching between the curved surface and the thermoelectric device is realized, and the potential of the scale production application of the large-area and high-array density thermoelectric device is improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of thermoelectric devices, and in particular relates to a laminated film type thermoelectric device and a spraying preparation method thereof. Background technique [0002] According to statistics: 90% of the world's energy is produced by burning fossil fuels as a heat source and then passing through a heat engine. The efficiency of the heat engine is only 30%-40%, which means that the world loses 15 terawatts (Terawatt) in vain a year. heat. [0003] Thermoelectric materials are functional materials that can convert heat and electricity. Two different types of thermoelectric materials, N and P, are connected at both ends to form a typical thermoelectric device. The two ends of the thermoelectric device are respectively placed in a high temperature state and a low temperature state to form a temperature difference. Due to the drive of thermal excitation, the P(N) type thermoelectric device T...
