Made below with reference to the attached drawing of specification by being further described to specific embodiment of the present utility model
The technical solution of the utility model and its benefits are clearer；And it is intended to explain the utility model and cannot understand
For limitations of the present invention.
Shown by referring to Fig.1, it is multistage that the embodiments of the present invention preferably provide a kind of Miniature digital projector
Radiator, it is characterised in that: it include mainboard 101, power management chip 102, heat conductive silica gel 103, radiator copper base 104,
Radiator copper pipe 105, radiator fins 106, fan 107 and DMD cooling fin 108；The heat conductive silica gel 103 is located at power management
Between chip 102 and radiator copper base 104, the power management chip 102 is connected on mainboard 101, the radiator copper
Pipe 105 is arranged in radiator fins 106；The fan 107 is located at below ray machine, and fan outlet connects radiator fins；DMD
Cooling fin 108 connects ray machine.The fan 107 has air inlet, and air inlet and ray machine interval are arranged.
Radiating principle and specific implementation are as described below:
First, the heat dissipation of the heat dissipation of ray machine light source led and high 102 power management chip of heating device of mainboard, radiator packet
Include radiator copper base 104, radiator copper pipe 105 and radiator fins 106.Wherein there is coolant liquid in radiator copper pipe 105.It dissipates
Hot device copper base 104 is directly in close contact LED pyrotoxin by heat conductive silica gel 103.The heat of ray machine light source led passes through thermal conductive silicon
Glue leads on radiator copper base 104 that (the high heating device power management chip 102 of mainboard is led heat by heat conductive silica gel 103
Onto radiator copper base 104), radiator copper base 104 is connected with radiator copper pipe 105, and the coolant liquid in copper pipe passes through temperature
Degree evaporation, heat is quickly led into other parts of copper pipe and be pressed together on copper pipe 106 groups of radiator fins on.Blowing-type wind
Fan 107 will be outside heat blowout machine.
The second, the heat dissipation of the heat dissipation of ray machine DMD device and casing internal.DMD device is by being fixed on device
108DMD cooling fin, communicates the temperature on cooling fin, and air inlet is located at cooling fin position by us, and 07 upper and lower ends of fan are inhaled
The principle of wind is allowed to generate air duct inside projector, while the heat and projector internal components on DMD cooling fin 108
The heat suction fan of generation will be outside heat blowout machine by the work of fan
107 air inlet of fan and air outlet generally pass through wind at two ends of different directions to form air duct in inside
Flowing, inside projector, the heat that heating device generates especially on mainboard is taken away.Mainboard is according to safety requirement, for height
In target temperature, physical interference cooling processing is carried out by the place that the flowing of air duct wind cannot cool down.Such as by copper base+lead
Hot silica gel is led in main radiator.According to the efficiency requirements of heat dissipation, fin can be copper material or aluminium.
There is coolant liquid in copper pipe, by the evaporation of temperature, reaches and heat is quickly led into the other parts of copper pipe and is pressed together on
In fins group on copper pipe.Blast type fan upper and lower ends air draught, the heat dissipation that outlet air is formed by radiator copper pipe and fins group
Device is blown out thermal energy by air outlet, drops the heat on the mainboard of bottom on thermal energy and ray machine in LED lamp panel.
Fan specifications can select suitably sized and air quantity according to actual needs.Projector in actual use, scene
Difference, the difference in geographical location, the difference in season, room temperature also can great changes have taken place.When room temperature is higher and higher, it is desirable that dissipate
The efficiency of heat is higher and higher.At this moment we detect ray machine lamp source temperature, passback by the temperature detector placed on ray machine lamp substrate
To master control, master control is according to preset temperature and fan voltage corresponding relationship.
Fan voltage value is adjusted, by controlling rotation speed of the fan, Lai Tigao radiating efficiency.When temperature reaches preset alarm value
When, generally 60 degree, then fan can be with nominal voltage, full speed running.So as to fast cooling.Cooling can not make temperature to fan at full speed
Degree is maintained in safe preset value, then system can cut off ray machine LED power supply, it is ensured that ray machine safety.
To form complete set, orderly, safe multistage cooling system.It is the service life, equal etc. safely to carry out in noise
Balance.Achieve the effect that intelligent temperature control.
In test, verifying temperature can be accurately measured with thermocouple.So as to precisely to radiating subassembly type selecting.It avoids out
Now old ox drags cart, or wastes one's talent on a petty job, excess waste phenomenon.Early period can also pass through the analog simulation that radiates, it is ensured that type selecting and design
Reasonability.In view of the variation of room temperature, and using the control for controling and useing noise of noise, surveyed at (25 degree) of normal room temperature
When amount verifying, fan should be made to be maintained in a nominal voltage median, so as to be used under most normal temperature, can had smaller
Noise.And under room temperature high field scape, fan can have She's amount to cool down.To enable projection light machine to have longer operational life
(10000-20000 hours), LED light plate temperature should be controlled at 50 degree hereinafter, DMD control is at 65 degree or less.Mainboard heating device
According to safety requirement, control within standard.
In use, mainly generating thermal component mainboard, ray machine obtains fan body and fin radiating block and concatenation fin heat dissipation
Effective transmitting heat of the heat conduction member of block, structure is simple, hot wind combined efficiency is high, it is safe and reliable, be effectively reduced manufacture at
Sheet, stable transmission, high yield rate feature.
Although describing the utility model by above-mentioned preferred embodiment, it is likely present that fall in this practical new
Change, displacement and equivalent scheme within the scope of type；A variety of alternatives are also likely to be present to realize the utility model.Cause
This, it is intended to the appended claims are construed to include in the true spirit and range for fall in the utility model it is all in this way
Change, displacement and equivalence；It should be understood by those skilled in the art that and the utility model is not limited to
The specific embodiment stated all falls within this reality using the improvement of techniques well known and substitution on the basis of the utility model
With novel protection scope, should be limited by each claim.
