Abstract
A temperature-differential generator by waste heat of engine is on an engine radiator as a semiconductor power generation module by using the reversibility of a semiconductor refrigeration/heating module. Use the temperature difference on both sides of the semiconductor power generation module which is produced by the heat produced by the running of the engine to generate electricity for electrical components and battery charge, so as to achieve the aim of waste heat utilization and energy saving.
Description
(1) technical field
The utility model relates to a kind of engine exhaust heat temperature difference electricity generation device, specifically is the device that utilizes the thermo-electric generation of cooling fluid and surrounding environment in the radiator on a kind of radiator (cooling water tank) that is installed in various engines (gasoline engine, diesel engine, natural gas engine etc.).
(2) background technology
Whole world energy scarcity becomes the serious problems that restrict economic development at present, and the exploitation regenerative resource has become the task of top priority.
And consume the various engines of a large amount of energy because problems such as the heat efficiency make portion of energy be converted into heat energy, for making the not overheated cooled engine artificially that needs again of engine, cause lot of energy to cause waste.
(3) summary of the invention
The purpose of this utility model provides a kind of temperature difference of utilizing engine coolant and surrounding environment, carry out the principle of thermo-electric generation and the engine exhaust heat temperature difference electricity generation device that designs based on the thermocouple effect of utilizing the solid semiconductor material, thereby improve energy utilization ratio effectively, reach purpose of energy saving.
The utility model is achieved in that the temperature difference of cooling fluid and surrounding air in the engine radiator is general and then can reaches 70 ℃-80 ℃ winter all more than 50 ℃ that the big temperature difference like this promptly is the available energy of semiconductor temperature differential generating.The utility model adopts the semiconductor refrigerating/thermal modules of technical maturation, because its energising refrigerating/heating and the invertibity that has the temperature difference promptly can generate electricity, the utility model uses it as the semiconductor electricity generation module.It is loaded on the radiator tube that fin is not installed, and one side is close to tube wall with insulation spacer, on the other hand finned.When coolant temperature was higher than ambient temperature, the semiconductor electricity generation module can produce certain electric current, thereby reached the purpose of utilizing the engine exhaust heat generating.
The beneficial effects of the utility model are partly to replace original charging generator on the engine, and by the power supply of semiconductor electricity generation module, so can reduce the power of charging generator on the former engine.When reaching the purpose energy savings of utilizing cogeneration, need not increase production cost.

(5) embodiment
The utility model is mainly by semiconductor electricity generation module (1) and heat-resisting insulation spacer (4), and semiconductor electricity generation module radiator (2), fixedly jump ring (6) is formed, and below in conjunction with accompanying drawing embodiment of the present utility model is described further.
The one side of the voltage that the utility model uses according to vehicle and each semiconductor electricity generation module (1) of selected semiconductor electricity generation module (1) all independently is fixed on the engine radiator cooling water pipe (5) through the pad (4) that insulate with fixing jump ring (6), and the then direct and semiconductor electricity generation module radiator (2) of the another side of semiconductor electricity generation module (1) is fixed into one group of generator unit with same fixedly jump ring (6).Water temperature when engine operation in the engine radiator water pipe (5) can reach 80 ℃-90 ℃, also can reach uniform temperature with semiconductor electricity generation module one side that it pastes mutually, and opposite side since semiconductor electricity generation module radiator (2) under the moving air effect, make its temperature lower, charge for the electrical appliance use with to storage battery thereby make semiconductor electricity generation module (1) the both sides generation temperature difference send electric current.According to power demand, several groups of generator unit connection in series-parallel are combined into the size that the generating assembly can arbitrarily determine power output, and insert the engine circuitry by generating assembly output electrode (7).For guaranteeing normal operation, behind each generator unit, all the GPF (General Protection False circuit can be set.During operation such as a certain generator unit break down and can it be withdrawed from combination by corresponding protection circuit, do not influence the operating state of assembly.
Claims (2)
1. an engine exhaust heat temperature difference electricity generation device is characterized in that semi-conductor thermo-electric generation module is installed on the engine radiator water pipe.
2. engine exhaust heat temperature difference electricity generation device according to claim 1, it is characterized in that the one side of semiconductor electricity generation module is close to through high temperature insulation pad and finless radiator water tube wall, another side then is close to semiconductor electricity generation module fin, is fixed on the radiator tube with fixing jump ring then.
