Micro convex array type thermoelectric generator heat exchange module

Abstract

The invention discloses a micro convex array type thermoelectric generator heat exchange module. A micro convex array is arranged on the upper end face of a heat exchange module base plate, the upper end of the micro convex array is in contact with the lower end face of an upper cover plate, a left side plate and a right side plate are arranged on the left side and the right side of the thermoelectric generator heat exchange module base plate respectively, and a flow inlet and a flow outlet are formed in the front end and the rear end of the thermoelectric generator heat exchange module respectively. Hot fluid enters the thermoelectric generator heat exchange module through the flow inlet, flows through the micro convex array for heat convection and flows out of the flow outlet. The whole thermoelectric generator heat exchange module is arranged on the upper portion of a thermoelectric power generation module, and is used as the hot end of a thermoelectric generator. The micro convex array structure is adopted, compared with a micro channel structure, the micro convex array type thermoelectric generator heat exchange module enables the heat convection area to be increased, and improves heat exchange efficiency. A rhombic staggered arrangement array is adopted in the micro convex array, the structure is more complex, the fluid is more disorganized, and the heat convection is severer. The micro convex array is simple in structure, easy to manufacture, low in production cost and suitable for mass production.

Description

Technical field [0001] The invention relates to a heat exchange module of a thermoelectric generator, in particular to a heat exchange module of a micro-convex array type thermoelectric generator. technical background [0002] Mankind is now facing a serious energy crisis. Therefore, people are constantly looking for new alternative energy sources. Thermoelectric material thermoelectric power generation is a new power generation method that uses the Seebeck effect to directly convert thermal energy into electrical energy. The semiconductor generator made of thermoelectric material thermoelectric power generation module can generate electricity as long as there is a temperature difference. It has a series of advantages such as cleanliness, no noise pollution, no toxic and hazardous substance discharge, high efficiency, long life, firmness, high reliability, and stability. It meets the requirements of green environmental protection and has important strategic significance for the s...
