Double-thermoelectric power generation device for solar water heater

Abstract

The invention discloses a double-thermoelectric power generation device for a solar water heater. The double-thermoelectric power generation device mainly comprises a solar heat water, a first thermoelectric power generation module, a second thermoelectric power generation module and a cold water circulating system, wherein a cylindrical channel is reserved at the center in a heat-insulating hot water tank of the solar heat water; the first thermoelectric power generation module having a cylindrical shape is mounted in the cylindrical channel; a cylindrical channel is also reserved at the center of the first thermoelectric power generation module; a first cold water pipe passes through the cylindrical channel at the center of the first thermoelectric power generation module; a first cold end face of the first thermoelectric power generation module is in contact with the first cold water pipe while a first hot end face is in contact with the hot water in the heat-insulating hot water tank; the second thermoelectric power generation module is arranged between the heat-insulating hot water tank and a cold water tank; a second cold end face of the second thermoelectric power generation module is in contact with the cold water tank while a second hot end face is in contact with the heat-insulating hot water tank; the heat-insulating hot water tank is connected with the cold water tank through a lower water pipe; the cold water tank is connected with a cold water source, a water pump and a heating radiator through the water pipe. The double-thermoelectric power generation device is capable of supplying hot water and generating electricity, is energy-saving and environment-friendly, is safe and high-efficient and is capable of effectively solving the problem of energy waste caused by hot water evaporation.

Description

technical field [0001] The invention relates to the technical field of solar energy, and more specifically relates to a solar water heater dual temperature difference power generation device. Background technique [0002] In China, solar water heaters have been very popular. Solar water heaters use solar energy to heat water, which is energy-saving and environmentally friendly, and is in line with the direction of green development. However, we know that users only need to use hot water up to 40-50 degrees, while solar water heaters can heat water to 70-90 degrees, or even higher, to evaporate the water in solar water heaters, thus causing a lot of damage. of energy wasted. At the same time, when it is rainy or the sunlight is weak in winter, it is often difficult for users to use water, so it is difficult for solar water heaters to meet the needs of users. Contents of the invention [0003] 1. Technical problems to be solved [0004] In order to solve the above technic...
