Abstract
The utility model discloses a cooling device for LCD backlight sheet. The high-powered light-emitting diodes arranged on the metal substrate, the backlight sheet is close to the light-emitting diodes and the LCD covers the backlight sheet. These components are arranged in the metal chamber that is copper or aluminum material. One side of the metal substrate is close connected with the metal substrate to help dissipating heat that is produced by light-emitting diodes and accumulates on the substrate though the surface of the metal chamber.
Description
Technical field
The utility model relates to a kind of heat abstractor, refers to a kind of LCD screen backlight plate heat radiating device special especially.
Background technology
At present the employed backlight of LCDs, utilize light emitting diode to produce light source mostly, Fig. 2 is the synoptic diagram of known product, grafting light emitting diode 22 on the PC plate 21 near light emitting diode 22, imports in the backlight 23 light source backlight 23 sides, reflective sheeting 25 places backlight 23 bottoms, LCDs 24 is covered on the backlight 23, makes light mirror from lower to upper, and outermost layer is by box capable 26 carryings.
Current LCDs is constantly pursued colored and size strengthens, and make the power that need have to consider to add big light-emitting diodes in the practice, but this measure makes virtually product internal temperature rise sharply, if do not increase heat abstractor, will directly influence the serviceable life of product.
The utility model content
The purpose of this utility model is to provide a kind of LCD screen backlight plate heat radiating device special, and it can effectively bring into play radiating effect under the situation that does not increase small product size.
To achieve these goals, technical solution of the present utility model is: a kind of LCD screen backlight plate heat radiating device special, powerful light emitting diode is plugged on the metal substrate, backlight is near light emitting diode, LCDs is covered on the backlight, wherein aforementioned components is inserted in the metal box capable of being made by copper, aluminum, and metal substrate one side is tight with box capable and is connected.
After adopting such scheme, the utility model mainly utilizes the original volume of product light emitting diode to be plugged in the metal substrate of energy heat radiator, relend and help copper that can quick conductive, the box capable that aluminum is made, make heat that metal substrate assembles be able to disperse fast to overflow by the surface of box capable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of known product.
Embodiment
See also shown in Figure 1, powerful light emitting diode 12 is plugged on the metal substrate 11, backlight 13 is near light emitting diode 12 bottoms, it connects reflective sheeting 15 and is placed in the metal box capable of being made by copper, aluminum 16, wherein metal substrate 21 1 sides and box capable 16 stick together by the heat conduction jelly, LCDs 14 are covered at last again.After the heat of powerful light emitting diode 12 generations is absorbed by metal substrate 11, i.e. metal box capable 16 is given in conduction, and heat avoids product to give birth to heat in the on average dissipation of the surface of metal box capable 16.
In sum, the utility model has the usability on progressive and the industry really.
