Embodiment Construction

[0019] Such as figure 1 As shown, the heat dissipation device of the built-in LED light source of the endoscope mainly includes a heat dissipation body and a DC fan 4 . The radiator is an inner hollow cylinder 2, such as figure 2 , the outer wall of the inner hollow cylinder 2 is snowflake-shaped, and the material of the inner hollow cylinder 2 is aluminum; A mounting column 3 is provided, and a DC fan 4 is connected and fixed on the mounting column 3, and the DC fan 4 adopts a 12V DC fan.

[0020] Heat-conducting glue is used between the LED light source 1 and the aluminum inner hollow cylinder 2, which not only can quickly transfer the heat emitted by the LED light source 1 to the aluminum inner hollow cylinder 2, but also plays the role of installing and fixing the LED light source 1 after the heat-conducting glue is solidified. , reducing additional LED fixtures. The inner hollow cylinder 2 made of aluminum is adopted, and its outer wall is in the shape of a snowflake ...

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 [0001] The invention relates to a heat dissipation device for a built-in LED light source in an endoscope, and belongs to the technical field of detection equipment. Background technique [0002] Endoscopes are used to help people observe parts of objects that cannot be directly seen by the human eye, and these parts are often dark and dull, so the light source is an indispensable component of the endoscope. At present, endoscopes mainly use LED cold light sources. In order to ensure long-term stable operation and ideal service life of LEDs, a good heat dissipation structure is required. [0003] At present, an external cold light source is usually used. This part has a large volume and good heat dissipation conditions, but it brings inconvenience to the user's operation. [0004] Later, a built-in LED light source was also proposed, which integrated the drive circuit with the LED. Although the device is small in size and compact in structure, the heat diss...
