A portable waste heat thermoelectric power generation device

Abstract

The invention provides a portable waste heat temperature differential power generation device which comprises an outer shell and a temperature differential power generation system. The outer shell comprises a shell body bottom plate and a shell body. The shell body is fixed with the shell body bottom plate through connecting pieces. The temperature differential power generation system comprises a heat insulation bottom plate, a cooling radiator, a temperature differential power generation chip and an energy storage heat exchanger. The cooling radiator and the energy storage heat exchanger are arranged on the heat insulation bottom plate. The temperature differential power generation chip is embedded in a boss arranged on the energy storage heat exchanger. The cooling radiator, the energy storage heat exchanger, the temperature differential power generation chip and the heat insulation bottom plate are fixed together through a compaction assembly. Sealing covers are respectively arranged on the cooling radiator and the energy storage heat exchanger. A thermal storage working medium used as a heat source of the temperature differential power generation chip is arranged in the storage energy heat exchanger. The energy storage heat exchanger transfers heat to a hot end of the temperature differential power generation chip, and the cooling radiator is arranged at a cold end of the temperature differential power generation chip. The portable waste heat temperature differential power generation device is free from noise, small in size, light in weight, low in maintenance cost in a later stage, and capable of using low-grade waste heat to generate electricity.
