Technical field
The present invention relates to a kind of radiating module, specifically it is a kind of be particularly suitable for making based on thermoelectric power generation principle it is small
Type electric appliance, the radiating module that intelligent multifunctional cup etc. uses.
Background technique
With the development of science and technology with the raising of living standards of the people, studies at present and developed various daily necessities, such as
Based on thermoelectric power generation principle hot water power generation Intelligent water cup, can show water in the cup temperature cup, can show various patterns in cup body
Cup, there are also glow cups, stirring cup etc., and these cups are without using external power supply, no replacement is required battery, only by
The temperature difference that the hot water poured into cup is formed at thermoelectric power generation device both ends directly converts electric energy for itself for the thermal energy of hot water
The circuit of installation uses, but these products in the market make the temperature difference since the radiating condition of thermoelectric power generation device is not good enough
The power that power generating device produces electricl energy is not big enough, and the time of power generation falls short of.
Determine that thermoelectric power generation device is produced electricl energy by the temperature difference of its cold and hot surface by the characteristic of thermoelectric power generation device, the temperature difference
More big then generated output is bigger, therefore, so that cold and hot two face of thermoelectric power generation device is obtained the bigger temperature difference and maintains the long-time temperature difference,
It is the key technology for promoting thermoelectric power generation device output power and generated energy.
The existing technology for improving thermoelectric power generation device cold and hot surface temperature difference between the two ends is divided into two major classes, first is that in thermoelectric power generation device
Cold end increases fin radiator, and radiator contacts with air, and heat is transmitted to air in the form of free convection, but due to sky
This mode radiating efficiency of gas free convection is lower, it is therefore desirable to and biggish fin radiator could generate ideal effect, by
In temperature difference power generation cup and compact electric apparatus finite volume, the volume of radiating fin is limited, heat dissipation area can not be accomplished very greatly, from temperature
The heat that poor power generating device cold end passes over can not be quickly transmitted in environment, therefore such technology can not make thermoelectric generator
Cold and hot two face of part generates the biggish temperature difference.
Second of technology places a heat-conducting medium accommodation chamber in thermoelectric power generation device cold end, and heat-conducting medium is led mounted in this
In thermal medium accommodation chamber.As disclosed in 2018 " hot water automatic mixing cup ", application No. is 201711034832.5, in the technology
Used heat-conducting medium selects liquid thermal conductivity media, preferably water.The technology is disadvantageous in that water or other liquid work
For heat-conducting medium, since water or other liquid heat storage capacities are limited, when absorbing heat, own temperature can continue to increase, and make to send out
The electric cold and hot two faces temperature difference of piece persistently reduces, and the generated energy of power generation sheet is unable to satisfy circuit requirements in several minutes, is unable to reach length
The effect of time power generation.
Summary of the invention
