Abstract

The utility model discloses an aluminium base board with novel heat radiation structure, the aluminium base edition of books body that includes conducting layer (1), medial ceramic heat -conducting layer (2) and the bottom of top layer, the outside of conducting layer has many semi -circular radiating groove (5), many semi -circular radiating groove parallel arrangement, the upside of pottery heat -conducting layer is equipped with many square radiating groove (6), many parallel equidistant the arranging of square radiating groove, the upside and the conducting layer contact of ceramic heat -conducting layer, the dorsal part of the aluminium base edition of books body is equipped with a plurality of heat dissipation posts (3), and a plurality of heat dissipation posts are the multirow multiseriate formation post array that dispels the heat of arranging, the heat dissipation post be square heat dissipation post. Be equipped with on each heat dissipation post one circular shape louvre (4). The heat dissipation post is 112, is 8 lines 14 and arranges. This aluminium base board with novel heat radiation structure easy to carry out, the heat dissipation goes with effect of thermal conductivity.

Description

A kind of aluminium base with radiating structure

Technical field

The utility model relates to a kind of aluminium base with radiating structure.

Background technology

Existing composite aluminum substrate, by conductive layer, middle ceramic layer and aluminium base body composition, owing to lacking necessary radiator structure, therefore, the heat that circuit devcie produces is not easy to scatter rapidly, therefore, is necessary to design a kind of aluminium base with radiating structure.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of aluminium base with radiating structure, and this aluminium base with radiating structure is easy to implement, heat radiation and good heat conduction effect.

The technical solution of utility model is as follows:

There is an aluminium base for radiating structure, comprise the aluminium base body of the conductive layer (1) of top layer, the ceramic layer (2) in middle level and bottom;

The outside of conductive layer has many semicircle radiating grooves (5); Many semicircle radiating groove is arranged in parallel;

The upside of ceramic layer is provided with many square radiating grooves (6), many parallel equidistant layouts of square radiating groove, the upside of ceramic layer and conductive layers make contact;

The dorsal part of aluminium base body is provided with multiple thermal column (3), and multiple thermal column is that multiple lines and multiple rows arrangement forms thermal column array;

Described thermal column is square thermal column.

Each thermal column is provided with a circular louvre (4).

Thermal column is 112, arranges arrangement in 8 row 14.

The setting direction of louvre and thermal column is the thickness direction of aluminium base body.

Beneficial effect:

The aluminium base with radiating structure of the present utility model, square groove on ceramic layer forms the ventilation hole in wiring board, and, the outside of conductive layer has many semicircle radiating grooves and too increases area of dissipation, further, the thermal column of multiple band louvres that aluminium base body is arranged, effectively can strengthen the heat dispersion of this aluminium base.Generally speaking, this aluminium base heat dispersion with radiating structure is good, can normal, long-term, the reliably working of effective guarantee circuit.
