Abstract

The invention provides a thermoelectric conversion device and system, and belongs to the technical field of thermoelectric conversion. Comprising a heat exchange heat sink shell, a liquid inlet and a liquid outlet are formed in the two ends of the heat exchange heat sink shell in the length direction respectively, and a plurality of rib walls are arranged in the heat exchange heat sink shell; the end where the liquid inlet is located is provided with a first arc-shaped area, and the end where the liquid outlet is located is provided with a second arc-shaped area. The first end, close to the liquid inlet, of each rib wall is bent towards the liquid inlet, and the second end, close to the liquid outlet, of each rib wall is bent towards the liquid outlet. In the plurality of first end parts, the bending radian of the first end part far away from the liquid inlet is greater than that of the first end part close to the liquid inlet; the distance from the first end part far away from the liquid inlet to the first arc-shaped area is smaller than the distance from the first end part close to the liquid inlet to the first arc-shaped area. By using the thermoelectric conversion device and system provided by the invention, the flow resistance of the liquid can be reduced while the heat exchange uniformity and the thermoelectric conversion efficiency are improved.

Description

technical field [0001] The present application relates to the technical field of thermoelectric conversion, in particular, to a thermoelectric conversion device and system. Background technique [0002] The thermoelectric conversion technology based on thermoelectric materials is one of the effective ways to directly convert low-grade heat energy into electrical energy. Since the heat exchange process in the thermoelectric conversion device has a significant impact on the thermoelectric conversion efficiency, the current thermoelectric conversion device is equipped with There is a turbulence structure to strengthen the heat transfer process, thereby improving the efficiency of the thermoelectric conversion system. [0003] For example, see figure 1 As shown, the thermoelectric conversion device includes a printed circuit board heat sink and a thermoelectric module stacked. Each layer of the printed circuit board heat sink is formed by stacking and welding three layers of st...
