Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, the structural representation of a preferred embodiment of the LED display casing that provides for the utility model.Said LED display casing 100 comprises the fore shell 110 of aluminum and the back cover 120 of aluminum; The inner surface of fore shell 110 and back cover 120 surround, and form the box-like structure with spatial accommodation (not shown), and the outer surface of fore shell 110 is provided with pcb board 130.In the present embodiment, fore shell 110 and back cover 120 all are aluminium matter, thereby heat transfer efficiency is high.Pcb board 130 unites two into one with led board; Pcb board 130 outside side arrays have some LED (not shown)s, also are provided with circuit and the IC chip of controlling said LED on the inner surface that simultaneously pcb board 130 and fore shell 110 are corresponding, and LED and IC chip are heater element; Can produce more heat during work; Need in time distribute, so fore shell 110 is provided with fin 111, fin 111 can effectively transmit the heat that LED and IC chip distribute and distribute.Being provided with in the spatial accommodation can be to the power supply 140 of pcb board 130 power supply, but the position of corresponding power 140 is provided with the louvre 121 that power supply source 140 heats distribute on the back cover 120.Removably connect through the corresponding locking member of being located at back cover 120 edges between fore shell 110 and the back cover 120, in the present embodiment, locking member is a screw.In the utility model; To being positioned at diverse location and the different device of the degree of heat on the LED display casing 100 corresponding radiator structure is set; In time the heat in the casing is distributed; Thereby under the situation that does not adopt the electric fan forced heat radiation, also can guarantee temperature equalization in the LED display casing 100, and satisfy the needs of operate as normal.
Please combine Fig. 3, Fig. 4, the front surface of fore shell 110 is provided with the heat radiation rib 112 with the corresponding applying of IC chip.Heat radiation rib 112 is set, has not only increased the area of dissipation of fore shell 110, key is to make and the IC chip of its applying, can directly through it most of heat fast, be directly passed to fore shell 110, thereby distribute the heat of IC chip fast and efficiently.
Further, as a prioritization scheme of present embodiment, be provided with thermal conductive silicon glue-line (not shown) between heat radiation rib 112 and the IC chip.Form this middle conductor of thermal conductive silicon glue-line through between heat radiation rib 112 and IC chip, applying heat conductive silica gel, the heat on the IC chip is distributed through fore shell 110, heat transfer efficiency improves greatly.
Further; With reference to Fig. 5, the heat on pcb board 130 is passed to fore shell 110 through the thermal conductive silicon glue-line, behind the heat transferred of LED to the fore shell 110; For fore shell 110 is distributed heat, some fin 111 are uniformly distributed in the edges on surface, fore shell 110 back.In the present embodiment, fore shell 110 is square tabular structure, and fin 111 is distributed in its edge, and like this, heat is from distribute all around simultaneously, and radiating rate is fast, and efficient is high.
Please refer again to Fig. 3, Fig. 6; Back cover 120 comprises bottom surface 122 and four sidewalls 123 that tilt to be connected with bottom edge; Back cover 120 is cover shape button and is located at the middle part of the rear side surface of fore shell 110, and around surface, fore shell 110 back, leaves the space that said fin 111 is set.Said power supply 140 is located in the spatial accommodation between fore shell 110 and the back cover 120, and near one of them sidewall 123 place of back cover 120, some louvres 121 are located on this sidewall 123.
In the optimized technical scheme, the bottom surface that the main heating face of power supply 140 is close to back cover 120 is provided with, and auxilliary heating face is near one of them sidewall 123 place of back cover 130.Because the surface area of back cover 120 is big and be aluminium matter; Back cover 120 is given in the most of directly conduction of the heat that power supply 140 distributes; And distribute fast through the outer surface of aluminum back cover 120; Also have the part heat then in the air in radiation to the spatial accommodation, exhale through the louvre on the sidewall 123 121 at last.
Further in the optimized technical scheme; Also be with the auxilliary heating face of power supply near relative another sidewall 123 of sidewall 123 on also offer some louvres 121; Thereby can make heat carry out convection current and distribute so that the air in the spatial accommodation produces convection effects, radiating effect is better.
To sum up, in the present embodiment, during 100 work of LED display casing, its radiating principle is: the heat that the IC chip on the pcb board 130 sends is passed to fore shell 110 through heat conductive silica gel, and exhales a part through the fin 111 on surface, fore shell 110 back; Simultaneously; Because fore shell 110 adopts aluminium to process; The aluminium good heat-transfer; So the heat in the closed area of the formation that fore shell 110 and pcb board 130 surround can effectively pass through aluminum fore shell 110,, can the normal demonstration of LED not impacted so the closed area is uniform low-temperature spaces in the LED display casing 100; It is more concentrated to be positioned at the heat that the power supply 140 of the spatial accommodation that fore shell 110 and back cover 120 enclose sends; It is the high-temperature region in the LED display casing 100; The heat that power supply 140 sends utilizes the outer surface of back cover 120 directly to distribute on the one hand; Utilize louvre 121 heat loss through convection on the sidewall 123 of back cover 120 on the other hand, thereby high-temperature region and the temperature difference of low-temperature space in the LED display casing 100 are reduced.Above-mentioned radiator structure utilizes the different radiating path that the heat of two higher warm areas in the LED display casing is distributed, and has reduced the temperature difference between the contiguous viewing area, thereby has guaranteed display quality.
The utility model also provides a kind of display screen (not illustrating in the drawings), and said display screen comprises a plurality of above-mentioned LED display casings.Adopt above-mentioned LED display casing,, and be provided with corresponding radiator structure to each heater members optimization in the casing because the LED display casing has adopted the fore shell and the back cover of aluminum; Thereby under the prerequisite that does not adopt fan; Also can in time heat be distributed, guarantee temperature equalization in the casing, improve display quality; And key is that the noise that does not have fan produces, thereby satisfied the needs of indoor screen to low noise.
More than be merely the preferred embodiment of the utility model,, any modification of being done within all spirit at the utility model and the principle, be equal to and replace and improvement etc., all should be included within the protection range of the utility model not in order to restriction the utility model.
