Find by prior art documents, number of patent application a kind of waste heat utilization device that has been 201210154997.7 Introduction To Cn Patent, this patent readme is: the present invention designs a kind of for internal combustion engine, the particularly waste heat utilization device of the internal combustion engine of motor vehicle, it has the used heat that actuating medium circulates therein and utilizes loop, evaporator is located at used heat and utilizes in loop for evaporating actuating medium, this actuating medium can be supplied with the waste gas of internal combustion engine, expansion machine is arranged on used heat and utilizes the downstream of the evaporator in loop for this actuating medium that expands, condenser is arranged on used heat and utilizes the downstream of the expansion machine in loop for condensation actuating medium, transmitting device is arranged on used heat and utilizes the downstream of condenser in loop for transmitting the actuating medium that utilizes loop at used heat, and heat-storing device.But because this device is comprised of parts such as evaporator, expansion machine, transmitting device, condenser and heat-storing devices, and need actuating medium, be not suitable for using in this special small space of projector.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of embedded projector radiating system is provided, can save the electric power energy that projector radiating system needs, can avoid again projector bulb because artificial improper operation causes damage simultaneously.
The present invention is achieved through the following technical solutions, the present invention includes projector outer cover, the first thermo-electric converting material, the second thermo-electric converting material, the 3rd thermo-electric converting material, the 4th thermo-electric converting material, support, DC fan, power storage module, control module and cable, the first thermo-electric converting material, the second thermo-electric converting material, the 3rd thermo-electric converting material, the 4th thermo-electric converting material is all embedded in the madial wall of projector outer cover, rack arrangement is at the lateral wall of projector outer cover, DC fan is arranged on support, the first thermo-electric converting material, the second thermo-electric converting material, the 3rd thermo-electric converting material, the 4th thermo-electric converting material is all connected with power storage module by cable, control module by cable respectively with power storage module, DC fan is connected.
Further, the first thermo-electric converting material, the second thermo-electric converting material, the 3rd thermo-electric converting material, the 4th thermo-electric converting material are all to utilize heat conductive silica gel to stick to the madial wall of projector outer cover in the present invention.
Further, the first thermo-electric converting material, the second thermo-electric converting material, the 3rd thermo-electric converting material, the 4th thermo-electric converting material are that symmetrical expression distributes in the present invention, the axis of projector outer cover and the dead in line of DC fan, and support is four leg cribbings.
In implementation process of the present invention, four thermo-electric converting materials utilize heat conductive silica gel to stick to the madial wall of projector outer cover, and the heat that so just projector can be given out is converted to electric energy, and electric energy drives DC fan to dispel the heat to projector again.Add in the present invention special power storage module and control module, the unnecessary electric energy that so can send each thermo-electric converting material stores, and can regulate in real time again the travelling speed of DC fan.
The invention has the beneficial effects as follows: save the electric power energy that projector radiating system needs, the while, because the present invention's use is passive cooling system, can avoid projector bulb because artificial improper operation causes damage effectively.Embedded projector radiating system provided by the invention will effectively reduce projector operating ambient temperature, improve instrument work efficiency, extend its serviceable life.
