Abstract

The utility model relates to a car power amplifier heat radiator, which consists of a metal framework, wherein, the radial cross section of the metal framework presents in a rectangular shape, and the circumference of the radial cross section of the metal framework is closed, and two outer side surfaces of the metal framework are respectively provided with more than two heat radiation ribs, and any of the heat radiation ribs is paralleled to the axial direction of the metal framework. The metal framework comprises the heat radiation ribs that are made of the aluminum material. The quantity of the heat radiation ribs of the heat radiator can be flexibly determined according to the requirements of the heat radiator, thereby increasing the heat radiation area and the heat radiation capacity; the components such as the upper cover plate, the side cover plate, connection screws and the like and relevant assembling procedures of the power amplifier can be reduced, and at the same time, the cost is reduced, and the structure strength is improved.

Description

The vehicle power amplifier radiator
Technical field:
The utility model relates to electricity field, relates in particular to the power amplifier that is used for hoot device, particularly a kind of vehicle power amplifier radiator.
Background technology:
The heat loss power of vehicle power amplifier integrated circuit (IC) chip constantly increases, but because the restriction of power of vehicle amplifier (hereinafter to be referred as power amplifier) installing space, can't in power amplifier, place fan, so the radiator of installing on the power amplifier integrate circuit chip can only dispel the heat by the mode of free convection.In the prior art, the vehicle power amplifier radiator can be arranged the negligible amounts of radiator fin owing to the restriction in space, and heat-sinking capability is relatively poor.And section be " " shape or " " power discharging radiator of shape or " ㄩ " shape, after extrusion molding, need thread mill drilling so that and the power amplifier coverplate parts assemble; this frame mode intensity is on the weak side; and the number of parts of power amplifier is more, and the manufacturing procedure and the assembly process of each part are more, are unfavorable for cost control.
Summary of the invention:
The purpose of this utility model is to provide a kind of vehicle power amplifier radiator, and described this vehicle power amplifier radiator will solve the technical problem that vehicle power amplifier radiator heat-dissipation ability is weak in the prior art, structural strength is not high, assembly process is more.
This vehicle power amplifier radiator of the present utility model is made of a metal framework, wherein, the radial section of described metal framework is rectangular, the all around sealing of metal framework in radial section, be provided with the radiated rib of two above numbers in two lateral surfaces of metal framework, any one described radiated rib all is parallel to the axial of metal framework.
Further, be provided with a smooth flat in the medial surface of described metal framework.
Further, metal framework comprises that radiated rib constitutes by aluminum.
Operation principle of the present utility model is: the cross section of power discharging radiator be " " shape, can an extrusion molding, constitute wholely, four outer surfaces all are used for heat radiation, can arrange the radiator fin on each face, can determine the fin number of radiator according to the requirement of radiator flexibly, increased area of dissipation and heat-sinking capability; Make the power amplifier assembly reduce parts such as upper cover plate, side cover plate, attachment screw and relevant assembly process, reduce cost simultaneously, strengthened its structural strength.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model utilizes the cross section to be the metal framework of " mouth " shape as radiator, can arrange the radiator fin on each outer surface of metal framework, the fin number of radiator be can determine according to the requirement of radiator flexibly, area of dissipation and heat-sinking capability increased; Make the power amplifier assembly reduce parts such as upper cover plate, side cover plate, attachment screw and relevant assembly process, reduce cost simultaneously, strengthened structural strength.
Description of drawings:
Fig. 1 is the structural representation of vehicle power amplifier radiator of the present utility model.
Fig. 2 is the radial section structural representation of vehicle power amplifier radiator of the present utility model.
Embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, vehicle power amplifier radiator of the present utility model is made of a metal framework 1, wherein, the radial section of described metal framework 1 is rectangular, the all around sealing of metal framework 1 in radial section, be provided with the radiated rib 3 of two above numbers in two lateral surfaces of metal framework 1, any one described radiated rib 3 all is parallel to the axial of metal framework 1.
Further, be provided with a smooth flat in the medial surface of described metal framework 1.
Further, metal framework 1 comprises that radiated rib 3 constitutes by aluminum.
In the present embodiment, the cross section of power discharging radiator be " " shape, can an extrusion molding, constitute wholely, four outer surfaces all are used for heat radiation, can arrange the radiator fin on each face, can determine the fin number of radiator according to the requirement of radiator flexibly, increased area of dissipation and heat-sinking capability; Make the power amplifier assembly reduce parts such as upper cover plate, side cover plate, attachment screw and relevant assembly process, reduce cost simultaneously, strengthened its structural strength.Power amplifier integrate circuit chip 2 is arranged in the smooth flat of metal framework 1 inboard.
