Delivery port and the water inlet connection of set, wherein, the cooling system also includes energy conversion device 5, the energy conversion device 5
Water inlet is connected with the outlet pipe 4.
By above-mentioned technical proposal, the partial heat energy of the higher coolant of the temperature flowed out from water jacket is turned by energy
Changing device is converted into the energy that can be utilized.Coolant temperature is reduced by energy conversion, cooling effect is reached, not only reduces
The loss scattered and disappeared with the energy of energy, and it is significant concerning the significant problem of human survival for global warming etc..
In order to make coolant sufficiently cool, in a preferred embodiment of the invention, the cooling system can be wrapped
Radiator 1 is included, the water inlet and delivery port of the radiator 1 are connected with the outlet pipe 4 and water inlet pipe 3 respectively.So, Ke Yitong
When coolant is cooled down by radiator 1 and energy conversion device 5.Certainly, it is enough in energy conversion device 5 by coolant
Heat conversion in the case of, radiator 1 can also be not provided with.
In the present invention, radiator 1 and energy conversion device 5 can suitably arrange.
Fig. 2 show the cooling system for engine according to a kind of embodiment of the invention, wherein the energy
Amount conversion equipment 5 and the radiator 1 are connected in series between the outlet pipe 4 and water inlet pipe 3, the energy conversion device 5
Delivery port be connected with the water inlet of the radiator 1.Specifically, the outlet pipe 4 is connected to entering for energy conversion device 5
The mouth of a river, the delivery port outflow through energy conversion device 5, and enter in radiator 1, the water of body 6 is then returned to by water inlet pipe 3
In set.
As shown in figure 3, being used as the cooling system for engine of another embodiment of the invention, the energy
Amount conversion equipment 5 and the radiator 1 are connected in parallel between outlet pipe 4 and water inlet pipe 3, and the energy conversion device 5 goes out
The mouth of a river is connected with the water inlet pipe 3.Specifically, the coolant in water jacket flows out through outlet pipe 4, in energy conversion device 5
Water inlet is divided into two-way：Energy conversion device 5 is flowed into all the way, and another road is finally led to by the inflow radiator 1 of connecting tube 11
Water inlet pipe 3 is crossed to return in water jacket.Because coolant is divided into two-way, flowing into the cooling liquid measure of energy conversion device 5 can influence to start
The temperature of body 6 of machine, therefore, can be in the energy conversion device 5 in order to be able to make engine be worked at appropriate temperature
Water inlet install volume control device, control coolant flow to the ratio between flow of radiator 1 and energy conversion device 5, from
And control coolant temperature.The specific mounting means of volume control device is known to those skilled in the art, no longer goes to live in the household of one's in-laws on getting married herein
State.In addition, volume control device can be properly selected, for example, volume control device can be electric-controlled thermostat.Automatically controlled section temperature
