Abstract

The utility model discloses an automobile power amplifier radiator which comprises a radiating frame made of aluminum alloy materials. A row of radiating fins are arranged on the outer side of the top of the radiating frame, cavities are symmetrically arranged on left side and right side of the radiating frame, the periphery of the radial section of each cavity is closed, at least two radiating fins are arranged on the outer side of each cavity, and screw holes are respectively arranged on the lower portions of the inner sides of the cavities. Due to the fact that the cavities are symmetrically arranged at two ends of the automobile power amplifier radiator and the radiating fins are arranged on the cavities, radiating area is enlarged due to the cavities and the radiating fins and increase of the radiating efficiency is facilitated. Furthermore, a cover board fixed by screws is used for preventing a power amplifier circuit board from loosening and falling off, and accordingly parts like coupling screws and related assembling procedures are reduced while cost is lowered.

Description

A kind of vehicle power amplifier radiator
Technical field
The utility model relates to electricity field, especially a kind of vehicle power amplifier radiator.
Background technology
Can use various electrical equipment in the life now, owing to all can produce heat during electrical work, people realize the effect of dispelling the heat through radiator is installed usually for this reason.Existing fin; The most simply be to realize that through thermal column or radiating groove are set on radiating bottom plate these heat radiating fin structures are single, for powerful electrical equipment; Under certain volumes condition, adopt this structure possibly not reach the radiating effect of requirement; Like the vehicle power amplifier IC chip, its heat loss power constantly increases, but because the restriction of power of vehicle 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 through 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.
The utility model of the patent No. 200820152242.2 provides a kind of vehicle power amplifier radiator; The cross section of this power discharging radiator is " mouth " shape; Each face arranges that all it is radiating effect that the radiator fin reaches; Though this design has better heat radiating effect, it is inconvenient that " mouth " shape structure can cause the power amplifier plate to install, and the material that uses simultaneously is more.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned technology, and a kind of radiating efficiency height, handling ease and circuit board vehicle power amplifier radiator easy for installation are provided.
The technical scheme that the utility model is realized is following: a kind of vehicle power amplifier radiator; Be made up of a heat-dissipating frame, described heat-dissipating frame is processed by aluminum alloy materials, and the top outer of heat-dissipating frame is provided with row's radiating fin; The heat-dissipating frame left and right sides is symmetrically arranged with cavity; The all around sealing of cavity in radial section, the cavity lateral surface is provided with at least two radiating fin, and screw hole is separately positioned on the bottom of described cavity medial surface.
Be provided with a smooth flat in the medial surface of described cavity.
The medial surface top of described cavity is provided with a draw-in groove.
The utlity model has following advantage:
The utility model two ends are symmetrically arranged with cavity, and cavity is provided with radiating fin, and the existence of cavity and radiating fin has increased area of dissipation; The power amplifier chip is arranged in the inboard smooth flat of cavity; Help improving radiating efficiency, the power amplifier integrated circuit board utilizes the cover plate of screw to prevent the loosening disengaging of power amplifier plate between two draw-in grooves; Thereby reduce part and relevant assembly processes such as attachment screw, reduce cost simultaneously.
Description of drawings
Fig. 1 is the radial section structural representation of the said vehicle power amplifier radiator of the utility model.
Among the figure: 1-heat-dissipating frame, 2-radiating fin, 3-cavity, 4-screw hole, 5-radiating fin, 6-draw-in groove.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
As shown in Figure 1, the described vehicle power amplifier radiator of the utility model is made up of a heat-dissipating frame 1, wherein; Heat-dissipating frame 1 is processed by aluminum alloy materials; The top outer of heat-dissipating frame 1 is provided with row's radiating fin 2, and heat-dissipating frame 1 left and right sides is symmetrically arranged with cavity 3, all around sealing of cavity 3 in radial section; Cavity 3 lateral surfaces are provided with at least two radiating fin 5, and screw hole 4 is separately positioned on the bottom of described cavity 3 medial surfaces.
As the further improvement of the utility model embodiment, be provided with a smooth flat in the medial surface of cavity 3.
As the further improvement of the utility model embodiment, the medial surface top of cavity 3 is provided with a draw-in groove 6.
The course of work of present embodiment is: the utility model adopts aluminum alloy materials to make; An extrusion molding; The power amplifier plate is fixed on the radiator through draw-in groove 6; Need not to reprocess separately screw hole 4, the end face of heat-dissipating frame 1 and the cover plate of power amplifier be through screw, and the power amplifier chip is arranged in the inboard smooth flat of cavity 3.
The utility model two ends are symmetrically arranged with cavity 3, and cavity 3 is provided with radiating fin 5, and the existence of cavity 3 and radiating fin 5 has increased area of dissipation, helps the raising of radiating efficiency.Through draw-in groove 6 is set, with the power amplifier integrated circuit board between two draw-in grooves 6, cover plate through screw on heat-dissipating frame 1 preventing the loosening disengaging of power amplifier plate, thereby reduce part and relevant assembly process such as attachment screw, reduce cost simultaneously.
