Background technology
60% energy could not be utilized in motor vehicle fuel, and most energy in fuel are unrestrained in the form of waste heat
Expense is fallen, in order that automobile engine is worked in optimum temperature range, it is necessary to be discharged into unnecessary heat in time with cooling water
In air, the cooling of water tank mainly has two ways：1）By the fin of automobile leading portion, radiated by natural convection air；
2）When water tank temperature is too high, starts fan and force cooling.Automobile is furnished with generator, is filled by fuel consumption to Vehicular accumulator cell
Electricity, therefore be not only in water tank cooling procedure to waste the waste heat of engine, and for the water in cooling water tank, also to enter
One step consumes motor vehicle fuel.
Thermoelectric cell is the product of a kind of technology maturation and commercialization, voltage and power and the temperature difference size of thermoelectric cell
Directly proportional, thermoelectric cell has been successfully applied to the cogeneration of vehicle exhaust, and its basic ideas is to utilize high-temperature tail gas and air
Between the larger temperature difference produce larger voltage, yet with tail gas in discharge process can fast cooling, this part has higher
The surface area of temperature is smaller, limits the quantity of thermoelectric cell in actual applications.The present invention proposes a kind of new thinking, utilizes
Thermo-electric generation between radiator and air, because water tank can provide larger surface area, thermoelectric can be dramatically increased
The quantity in pond, by the series connection and parallel connection of circuit, voltage and power that increase thermoelectric cell generates electricity.
Utilize the high temperature thermo-electric generation of vehicle exhaust at present, the temperature of vehicle exhaust is up to 800 ~ 1300K, and the temperature difference is got over
Greatly, more contribute to obtain larger power, present application is based on this thinking.However, because exhaust temperature can be quick
Decline, the region area of real high temperature is limited, and a large amount of waste heats are to pass through cooling-water drain caused by engine work
, this partial heat energy is not utilized, and in order that cooling water tank cooling fan work also need battery consumption electric energy and
Fuel.Cooling water tank thermo-electric generation overall structure proposed by the present invention is simple, movement-less part, without work noise, pollution-free, nothing
Tremble.
Utility model content
For solve the utility model proposes technical problem, technical scheme provided by the utility model is：
A kind of automobile-used cooling water tank temperature difference electricity generation device, including tank radiating plate, the bottom surface of the tank radiating plate are provided with
Thermoelectric cell, the thermoelectric cell are fixed on the water tank wall of automobile engine cooling water tank, the bottom surface of thermoelectric cell and water tank

Further to improve, the thermoelectric cell is fixed on tank radiating plate and automobile engine cooling water by bolt
Between tank wall, thermoelectric cell on the contact surface of water tank wall and fin with being coated with heat-conducting glue.
Further to improve, the thermoelectric cell is Bi2Te3And its solid-solution material is made.
The beneficial effects of the utility model include：The utility model can significantly increase the quantity of thermoelectric cell, fully
Using the waste heat of cooling water tank, product is small into big, improves the efficiency of cogeneration.Automobile fuel consumption is reduced, reduces motor vehicle exhaust emission.
Existing mobile generator needs to consume fuel, and cooling water tank thermo-electric generation can replace existing vehicle-mounted hair
Motor, lower automobile fuel consumption, reduce exhaust emission.Be particularly suitable for use in hybrid electric vehicle, and hybrid electric vehicle is furnished with a large amount of batteries,
Its charging relies on mobile generator at present, with cooling water tank thermo-electric generation to its battery charging, can further reduce mixing
The oil consumption of power car, reduce pollution.
Brief description of the drawings
Fig. 1 is the utility model schematic device；
In figure, 1 is the water tank wall of cooling water tank, and 2 be thermoelectric cell, and 3 be tank radiating plate, and 4 be wire.
Embodiment
The technical solution of the utility model is further described below in conjunction with drawings and examples.
As shown in figure 1, a kind of automobile-used cooling water tank temperature difference electricity generation device, including tank radiating plate 3, the tank radiating plate
3 bottom surface is provided with thermoelectric cell 2, and the thermoelectric cell 2 is fixed on the water tank wall 1 and fin of automobile engine cooling water tank
Between 3, thermoelectric cell 2 is brought into close contact with water tank wall 1 and fin 3.Thermoelectric cell is connected with voltage stabilizing control electricity by wire
Road, mu balanced circuit are connected with battery by wire.12V or 24V Vehicular accumulator cells can be selected in battery.
When this TRT is installed, thermoelectric cell is clamped by bolt and is fixed on tank radiating plate and automobile engine
Between cooling water tank, thermoelectric cell 2 on the contact surface of water tank wall 1 and fin 3 with being coated with heat-conducting glue.This TRT
Installation fixation can be carried out using other forms.As long as thermoelectric cell 2 is kept to be brought into close contact with water tank wall 1 and fin 3.
The thermoelectric cell can select Bi as needed2Te3And its solid-solution material is made.
As illustrated, when the present apparatus works, hot junction of the surface of water tank wall 1 as thermoelectric cell 2, connect with free convection air
Cold end of the tactile tank radiating plate 3 as thermoelectric cell, cross-ventilated direction is perpendicular to paper in figure.Thermoelectric cell 2 passes through
Wire is connected with controlling circuit of voltage regulation, is mainly used in burning voltage, after voltage exceedes the voltage needed for battery charging, to storage
Battery charges.
The temperature difference between voltage caused by thermoelectric cell and power and water tank surface temperature and atmospheric temperature is relevant, this temperature
Difference is bigger, and the voltage and power that thermoelectric cell provides are also bigger.In cold start, particularly under winter relatively low temperature, cooling
The temperature of water tank is relatively low, and with the extension of engine operating duration, the temperature of cooling water can step up, and show as thermoelectric cell
The voltage and power of output are also what is be stepped up, i.e., the voltage that thermoelectric cell provides is unstable, and this just needs to use voltage stabilizing
Control circuit burning voltage.
