Abstract
The utility model relates to a vehicle-mounted multimedia heat radiation structure, comprising a bottom cap and a circuit board fixed inside the bottom cap. A heating element is arranged on the circuit board. The circuit board also comprises a radiating fin arranged on one side of the heating element and a support on the other side of the heating element. By virtue of using a fastener to penetrate the radiating fin and the heating element sequentially the heating element and the radiating fin are simultaneously fixed on the support. The radiation structure also comprises a fan generating wind blowing from the inner part of the bottom cap to the outer part. An air outlet is also arranged at the corresponding part of the bottom cap, and a blowing mode with the wind from the inner part to the outer part is realized. The vehicle-mounted multimedia heat radiation structure can discharges the heat to the outer part of a machine at the same time as the heating element generates heat, hence, the temperature in the inner part of a cabinet is effectively reduced, heat radiation effect is very good, and dust in the inner part of the machine is brought out when the heat is blown off. The environment of the inner part of the machine can be kept clean.
Description
Technical field
The utility model relates to vehicle mounted multimedia technical field, particularly a kind of vehicle mounted multimedia radiator structure.
Background technology
The radiating mode that forces of existing vehicle mounted multimedia main frame mainly adopts the mode by " blowing inward " outward, and this radiating mode exists that radiating efficiency is low, the defect of laying dust.Radiating efficiency is low, can cause machine intimate temperature high.High temperature can make the electronic component life-span reduce, and even damages electronic component, makes product failure.The risk that the electronic component of laying dust on can increasing circuit plate is short-circuited.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle mounted multimedia radiator structure with high water-proof function.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of vehicle mounted multimedia radiator structure, it comprises bottom and is fixed on the circuit board of bottom inside, on described circuit board, be provided with heater element, on described circuit board, also comprise the fin that is arranged on heater element one side and the support that is arranged on heater element opposite side, utilize securing member sequentially to pass respectively fin and heater element, heater element and fin can be fixed on support simultaneously; This radiator structure also comprises that a wind direction blows to outside fan from bottom inside.
In a preferred embodiment, the position of the corresponding described fan of described bottom is formed with air outlet.
In a preferred embodiment, a side and the described heater element of described fin are close to, and opposite side is formed with the groove for accommodating described fan; On described fin, be formed with for described heater element is produced to heat and diffuse to outside fin.
In a preferred embodiment, described support can be coated on the outer surface of described fin completely.
In a preferred embodiment, described fan is fixed on described circuit board.
In a preferred embodiment, described fan is fixed on described bottom.
In a preferred embodiment, described fin and support all adopt aluminum alloy materials.
The beneficial effect of the utility model vehicle mounted multimedia radiator structure is: by fin and the support with heat sinking function are set in heater element both sides, and on fin, be provided with for heat on fin is blowed to outside fan, also arrange in the corresponding position of bottom with air outlet, to reach the blowing pattern of " by inner firmly outer ".This vehicle mounted multimedia radiator structure can blow in time temperature to machine exterior when heater element produces heat, effectively reduce the temperature of cabinet inside, radiating effect is very good, and in blowing temperature, the dust of machine intimate can also be taken away, therefore machine intimate just can keep a relatively dry clean environment.
Brief description of the drawings
Fig. 1 is the perspective exploded view of vehicle mounted multimedia radiator structure in an embodiment.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model vehicle mounted multimedia radiator structure is described in further detail.
Refer to Fig. 1, a kind of vehicle mounted multimedia radiator structure, it comprises bottom 10 and is fixed on the circuit board 20 of bottom 10 inside, is provided with multiple heater elements 40 on circuit board 20.Understandable, join this radiator structure also have front panel and top cover, because of the key protection point of non-this case, thus herein omit describe.
On circuit board 20, also comprise fin 50 and support 30, wherein, fin 50 is arranged on a side of heater element 40, support 30 is arranged on the opposite side of heater element 40, and, fin 50, heater element 40 and support 30 are and are set up in parallel, heater element 40 be arranged on fin 50 and between between 30.
Preferably, this radiator structure also comprises a fan 60, and this fan 60 is arranged between fin 50 and bottom 10 afterbodys, blows to outside for the heat on heat and fin 50 that heater element 40 is produced; Bottom 10 is formed with corresponding air outlet 11 to position that should fan 60.
One side and the heater element 40 of fin 50 are close to setting, opposite side is formed with the groove 51 for accommodating fan 60, the position of the interior corresponding heater element 40 of this groove 51 is formed with the first fixing hole (not shown), is also formed with many fins equally distributed, that conduct for the heat that heater element 40 is produced on fin 50.
Support 30 is the mad body of an interior sky, it can be coated on the outer surface of fin 50 completely, and, also be formed with the second fixing hole (not shown) at it with the position that on fin, the first fixing hole is corresponding, utilize securing member respectively sequentially through the second fixing hole on the first fixing hole, heater element 40 and the support 30 of fin 50, heater element 40 and fin 50 can be fixed on support 30 simultaneously.
In a preferred embodiment, fan 60 is fixed on bottom 10 and with air outlet, and in other embodiments, fan also can be fixed on circuit board, these two kinds of fixed forms all need fan to be embedded in the groove of fin, so can better transfer of heat.
For transfer of heat better and very timely, the fin using in this case and support all adopt aluminum alloy materials to make.
The utility model vehicle mounted multimedia radiator structure, by fin and the support with heat sinking function are set in heater element both sides, and on fin, be provided with for heat on fin is blowed to outside fan, also arrange in the corresponding position of bottom with air outlet, to reach the blowing pattern of " by inner firmly outer ".This vehicle mounted multimedia radiator structure can blow in time temperature to machine exterior when heater element produces heat, effectively reduce the temperature of cabinet inside, radiating effect is very good, and in blowing temperature, the dust of machine intimate can also be taken away, therefore machine intimate just can keep a relatively dry clean environment.
Although description of the present utility model is carried out in conjunction with above specific embodiment,, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all such substituting, improve and change are all included in the spirit and scope of attached claim.
