Abstract
The invention provides a heat dissipating device for an LED light source with an embedded endoscope, which comprises a radiator and a direct-current fan, wherein the radiator is an aluminum hollow cylinder with a snowflake-shaped outer wall; the LED light source is fixed with the front end of the aluminum hollow cylinder via heat conducting glue; the back end of the aluminum hollow cylinder is provided with a mounting pillar in a projecting way; and the 12V direct-current fan is connected and fixed to the mounting pillar. When the heat dissipating device is used, heat of the LED light source is transmitted in time via the aluminum hollow cylinder, and the fan blows strong wind to the aluminum hollow cylinder. Therefore, the heat dissipating device achieves satisfactory continuous heat dissipation effect, effectively ensures that the junction temperature of the LED is lower than the specified value, ensures the LED to run stably for a long time, and is worthy of popularization and application.
Description
Technical field
The present invention relates to a kind of heat abstractor of LED light source with embedded endoscope, belong to the checkout equipment technical field.
Background technology
Endoscope is used to help people to observe the object part that human eye can't directly be seen, and these parts are often dark unglazed, so light source is the indispensable building block of endoscope.Current endoscope mainly adopts the LED cold light source, for guaranteeing long-time steady operation of LED and desirable service life, needs good radiator structure.
Usually adopt the external cold light source at present, this piece volumes is bigger, and radiating condition is good, but has brought inconvenience to user's operation.
Also proposed a kind of LED light source with embedded afterwards, drive circuit and LED had been combined as a whole.Though little, the compact conformation of this device volume, radiating effect is very undesirable.
Therefore, need design a kind of novel radiator structure at LED light source with embedded.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of heat abstractor of LED light source with embedded endoscope is provided, be intended to effectively improve radiating effect.
Purpose of the present invention is achieved through the following technical solutions:
The heat abstractor of LED light source with embedded endoscope, comprise radiator and DC fan, characteristics are: described radiator is interior hollow circular cylinder, led light source fixes by the front end of heat conduction glue and described interior hollow circular cylinder, the rear end of hollow circular cylinder convexes with erection column in described, is connected and fixed DC fan on erection column.
Further, the heat abstractor of above-mentioned LED light source with embedded endoscope, the outer wall of described interior hollow circular cylinder is snowflake type.
Further, the heat abstractor of above-mentioned LED light source with embedded endoscope, the material of described interior hollow circular cylinder is an aluminium matter.
Again further, the heat abstractor of above-mentioned LED light source with embedded endoscope, described DC fan are the 12V DC fan.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
Modern design of the present invention is coated heat-conducting glue with led light source and is fixed in the aluminium matter on the hollow circular cylinder, and the 12V DC fan is installed at the rear portion of hollow circular cylinder in aluminium matter, hollow circular cylinder in the aluminium matter is dried the continuous radiating effect of realizing ideal by force by fan.Thereby assurance LED junction temperature is guaranteed the long-time steady operation of LED less than setting, prolongs the service life of LED; Cost is low, result of use is very satisfied, and application prospect is very good.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: structural representation of the present invention;
Fig. 2: the structural representation of interior hollow circular cylinder.
The implication of each Reference numeral among the figure:
Hollow circular cylinder in the 1-LED light source, 2-, 3-erection column, 4-DC fan.
The specific embodiment
As shown in Figure 1, the heat abstractor of LED light source with embedded endoscope mainly comprises radiator and DC fan 4.Radiator is interior hollow circular cylinder 2, and as Fig. 2, the outer wall of interior hollow circular cylinder 2 is snowflake type, the material aluminium matter of interior hollow circular cylinder 2; Led light source 1 fixes by the front end of heat conduction glue and interior hollow circular cylinder 2, convexes with erection column 3 in the rear end of interior hollow circular cylinder 2, is connected and fixed DC fan 4 on erection column 3, and DC fan 4 adopts the 12V DC fan.
Use heat conduction glue in led light source 1 and the aluminium matter between the hollow circular cylinder 2, not only the heat that led light source 1 can be sent is transferred to hollow circular cylinder 2 in the aluminium matter rapidly, and heat-conducting glue plays after solidifying and installs and fixes led light source 1 effect, reduced the additional LEDs fixture.Adopt hollow circular cylinder 2 in the aluminium matter, its outer wall is flakes, is issued to the area of dissipation of maximum at the volume of minimum.Be equipped with the 12V DC fan and dispel the heat, compare with adopting the heat radiation of 5V DC fan, advantage is: not only increased the wind flow in the unit interval, and reduced the circuit of 12V power conversion to the 5V power supply, reduced cost, dwindled volume.
During concrete the application, the heat that led light source 1 sends is transferred to hollow circular cylinder 2 storages in the aluminium matter rapidly, by hollow circular cylinder the last 2 blowing in 4 pairs of aluminium matter of 12V DC fan, heat is scattered rapidly, has realized good continuous radiating effect.
In sum, the present invention designs uniqueness, novel structure, promptly by optimal design the heat of led light source is in time sent out through the good heat radiating body, thereby assurance LED junction temperature is guaranteed the long-time steady operation of LED less than setting, prolongs the service life of LED; Significantly reduced cost, improved economic benefit, application should be widely promoted.
What need understand is: though the foregoing description is to the present invention's detailed explanation of contrasting; but these explanations are just illustrative to the present invention; rather than limitation of the present invention, any innovation and creation that do not exceed in the connotation of the present invention all fall within the scope of protection of the present invention.
