Background technology
60% energy could not be utilized in motor vehicle fuel, and the 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 to Vehicular accumulator cell by fuel consumption
Electricity, therefore the waste heat for wasting engine is not only in water tank cooling procedure, 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
It is directly proportional, thermoelectric cell has been successfully applied to the cogeneration of vehicle exhaust, its basic ideas is using 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, and the quantity of thermoelectric cell is limited 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, can dramatically increase thermoelectric
The quantity in pond, by the series connection and parallel connection of circuit, increases voltage and power that thermoelectric cell generates electricity.
The high temperature thermo-electric generation of vehicle exhaust has been utilized at present, and 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 produced during engine work are by cooling-water drain
, 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.
The content of the invention
To solve technical problem proposed by the present invention, the technical scheme that the present invention is provided 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 is provided with the temperature difference
Battery, the thermoelectric cell is fixed on the water tank wall of automobile engine cooling water tank, and the bottom surface of thermoelectric cell is tight with water tank wall
Closely connected conjunction.
Further to improve, the thermoelectric cell is connected with controlling circuit of voltage regulation by wire, and mu balanced circuit passes through wire
It is connected with battery.
It is further to improve, it is characterised in that the battery is 12V or 24V Vehicular accumulator cells.
Further to improve, the thermoelectric cell is fixed on tank radiating plate and automobile engine cooling water by bolt
Between tank wall, heat-conducting glue is coated with thermoelectric cell and the contact surface of water tank wall and fin.
Further to improve, the thermoelectric cell is Bi2Te3And its solid-solution material is made.
Beneficial effects of the present invention include：The present invention can significantly increase the quantity of thermoelectric cell, make full use of cooling
The waste heat of water tank, product is small into big, improves the efficiency of cogeneration.Automobile fuel consumption is reduced, motor vehicle exhaust emission is reduced.
Existing mobile generator needs to consume fuel, and cooling water tank thermo-electric generation can replace existing vehicle-mounted hair
Motor, lowers automobile fuel consumption, reduces exhaust emission.It is particularly suited for hybrid electric vehicle, hybrid electric vehicle is furnished with a large amount of batteries,
It charges and 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, reduction pollution.
Brief description of the drawings
Fig. 1 is apparatus of the present invention schematic diagram；
In figure, 1 is the water tank wall of cooling water tank, and 2 is thermoelectric cell, and 3 is tank radiating plate, and 4 is wire.
Specific embodiment
Technical scheme 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 and controls electricity by wire
Road, mu balanced circuit is connected with battery by wire.Battery can select 12V or 24V Vehicular accumulator cells.
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, heat-conducting glue is coated with thermoelectric cell 2 and the contact surface of water tank wall 1 and fin 3.This TRT
Installation fixation can be carried out using other forms.As long as keeping thermoelectric cell 2 to be brought into close contact with water tank wall 1 and fin 3.
The thermoelectric cell can as needed select Bi2Te3And its solid-solution material is made.
As illustrated, when the present apparatus works, the surface of water tank wall 1 connects as the hot junction of thermoelectric cell 2 with free convection air
Tactile tank radiating plate 3 as thermoelectric cell cold end, cross-ventilated direction is perpendicular to paper in figure.Thermoelectric cell 2 passes through
