The structure combines the aerodynamic principle, through the special structural design of fin, can with the heat of power amplifier fast through in giving off the air, improve power amplifier life, improve the job stabilization nature of navigator.
Description
Technical field
The utility model relates to technical field of heat dissipation, particularly the heat radiating fin structure of vehicle mounted guidance power amplifier.
Background technology
Along with the development of science and technology, navigator product has been widely used in automotive system.During navigator work, the power discharging device of navigator gives out a large amount of heats, when power amplifier and heat radiating fin structure design or when installing reasonable not, the heat that power amplifier gives out is difficult to distribute in time, can have a strong impact on the normal work and use life-span of acoustic electronic components and parts and power amplifier.
Utility model content
For the problems referred to above, the utility model provides a kind of Novel navigator power amplifier radiator structure.
Described Novel navigator power amplifier radiator structure, comprise inner casing and casing backboard, fin that power amplifier and acoustic electronic components and parts are installed, fin is bolted on casing backboard, described fin comprises the heat-conducting plate of fitting with casing backboard and the heat-dissipating fin laterally extended respectively to the one side deviating from casing backboard from the upper and lower dual-side of heat-conducting plate, makes fin side form C type groove.
Preferably, the contact-making surface of described fin and casing backboard arranges projection, make to form air circulation chamber between casing backboard and fin.
Preferably, the first projection that the position that described projection comprises power amplifier in corresponding casing is arranged fully contacts with fin to make power amplifier; Described projection also comprises installation site, corresponding casing both sides and arranges the second projection to ensure that fin is installed firm.
Preferably, described heat-dissipating fin arranges louvre; Described louvre is oval for being preferably.
Radiator structure described in the utility model has following significant advantage: (1) described structure adopts single ingot (referring generally to the machine that thickness is less than or equal to 5cm) structural design, All hosts requirement can be met, highly versatile, (2) described fin and power amplifier contact position are designed to boss, fin and power amplifier can be made to form good contacting, simultaneously and backboard form certain air chamber, take away the heat on fin when being conducive to air formation convection current; (3) fin has the fin stretched out, overall C-shaped, can increase the contact area of fin and air, simultaneously also can the connecting line of protecting and navigation instrument and automobile; (4) fin C type design, and both sides correspondence opens ellipse hole up and down, is conducive to the heat taken away when air forms convection current on fin; (5) separated in casing with fin by backboard, the heat of fin can be avoided to reflux again and enter in casing, affect the normal work of machine.

Embodiment
For making those skilled in the art better understand the utility model, below in conjunction with embodiment, the utility model is described in further detail.
As Figure 1-4, navigator power amplifier radiator structure described in the present embodiment comprises casing 10 and casing backboard 20, fin 30, the power amplifier that sound equipment is used and other acoustic electronic components and parts etc. are installed in casing 10, together with casing 10, backboard 20 are screwed with fin 30.
Heat radiating fin structure as shown in Figure 5,6, comprise the heat-conducting plate 31 of fitting with casing backboard 20, from the heat-dissipating fin 32 that the upper and lower dual-side of heat-conducting plate extends respectively to the one side deviating from casing backboard, and oval louvre 33 is set on heat-dissipating fin 32, then fin is overall C-shaped from the side.The contact-making surface of heat-conducting plate 31 and casing backboard 20 is arranged several projection to make to form the cavity 40 that can supply air circulation between heat-conducting plate and casing backboard.On heat-conducting plate 31, in protruding 35 general corresponding casings, the position of power amplifier is arranged to make power amplifier fully contact with fin; In addition, in order to ensure that fin is installed firm, protruding 34 are also arranged in installation site, corresponding casing both sides.In order to increase radiating effect, fin generally adopts the material of the good heat dissipation effect such as such as aluminium alloy.
Backboard is generally plane, do due to fin 30 and power amplifier contact position and protruded process, and fin 30 and casing 10 contact point have also been made and protrude process, three is screwed rear backboard and is caught in the middle, backboard and casing are close to, and just define an air chamber 40 in the middle of backboard and power amplifier, be beneficial to air circulation heat radiation.When power amplifier works, power amplifier heat can transfer heat to fin rapidly by the contact site of fin 30 and power amplifier, and heat discharges to ambient air by fin more further.
In addition, due to the partition effect of backboard, the high temperature air being transmitted to fin surface directly can not enter casing internal, but is blocked in the air chamber between backboard and fin.Then by cross-ventilation, the heat in air chamber will be rapidly to flowing, reach the effect of quick heat radiating.
Aerodynamic principle has been taken into full account in the utility model, increase fin on a heat sink, fin opens ellipse hole simultaneously, increase the contact-making surface of fin and air, ellipse hole can promote distributing of fin heat, improve rate of heat dissipation, make the radiating effect of single ingot machine structure reach the effect of common double ingot machine.
Further, fin entirety is C-shaped, can also effectively protecting and navigation instrument to external plug-in component, certain space can be formed during installation and place wire harness.
The heat of power amplifier, in conjunction with aerodynamic principle, by the structural design that fin is special, can quickly move through and be dispersed in air by structure described in the utility model, improves power amplifier useful life, improves the job stability of navigator.
Above-described embodiment is only preferably implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to the protection range of utility model.
