Abstract
The utility model relates to a kind of aluminium alloy heat radiator, it comprise for absorption circuit chip on board heat endothermic substrate and be wholely set several fin on endothermic substrate, described endothermic substrate and fin are aluminum alloy material, described endothermic substrate is circular, fin spirally distributes on endothermic substrate, fin is at the middle part of endothermic substrate around formation centre bore, and the aperture of centre bore is 1-5cm.Aluminium alloy heat radiator of the present utility model, can strengthen radiating efficiency, and can prevent from piling up in dust space between fins, is convenient to the cleaning of dust.
Description
Technical field
The utility model relates to electronic components field, particularly a kind of aluminium alloy heat radiator.
Background technology
In order to the heat radiation of heater element on wiring board, usually radiator to be set on heater element, the structure of existing radiator is varied, and its basic structure comprises a matrix and some fin, and the two is generally one-body molded, fin is usually with a determining deviation distributed rectangular, be parallel to each other between fin, this radiator after mounting, only has the air-flow of specific direction the heat on fin could to be taken away by the space between fin, therefore, radiating efficiency is lower.
Summary of the invention
The purpose of this utility model is, for the low problem of existing radiator heat-dissipation efficiency pointed in background technology, to provide a kind of aluminium alloy heat radiator that can solve foregoing problems.
The technical scheme realizing goal of the invention of the present utility model is as follows:
A kind of aluminium alloy heat radiator, it comprise for absorption circuit chip on board heat endothermic substrate and be wholely set several fin on endothermic substrate, described endothermic substrate and fin are aluminum alloy material, described endothermic substrate is circular, fin spirally distributes on endothermic substrate, fin is at the middle part of endothermic substrate around formation centre bore, and the aperture of centre bore is 1-5cm.
In order to strengthen endothermic substrate and the contact area needing the chip dispelled the heat, accelerate heat radiation, the bottom of described endothermic substrate is provided with the groove adapted with chip form.
The advantage of aluminium alloy heat radiator of the present utility model is: aluminium alloy heat radiator of the present utility model have employed the endothermic substrate of aluminium alloy, the heat absorption efficiency to chip can be accelerated, fin distributes with spiral dress on endothermic substrate, at the middle part of endothermic substrate around formation centre bore, no matter air-flow from what angle is blown over, all can arrive in centre bore by part heat sink, form gas channel, therefore, it is possible to strengthen the radiating efficiency of radiator.And the fin of this spiral, along the radial direction of endothermic substrate, gap between fin reduces gradually, this structure not easily piles up dust, even if having some dust accretions between fins, also clear up very well, only the gap of hairbrush between fin need be used to brush laterally and dust can be cleared up away.And aluminium alloy heat radiator structure of the present utility model is simple, low cost of manufacture, is more convenient for producing and application.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of aluminium alloy heat radiator of the present utility model;
Fig. 2 is the bottom schematic view of endothermic substrate of the present utility model;
In figure, 1 is endothermic substrate, and 2 is fin, and centered by 3 hole, and 4 is groove.
Embodiment
See figures.1.and.2 shown a kind of aluminium alloy heat radiator, it comprise for absorption circuit chip on board heat endothermic substrate 1 and be wholely set several fin 2 on endothermic substrate 1, described endothermic substrate 1 and fin 2 are aluminum alloy material, described endothermic substrate 1 is circular, fin 2 spirally distributes on endothermic substrate 1, fin 2 is at the middle part of endothermic substrate 1 around formation centre bore 3, and the aperture of centre bore 3 is 1-5cm.
In order to strengthen endothermic substrate 1 and the contact area needing the chip dispelled the heat, accelerate heat radiation, the bottom of described endothermic substrate 1 is provided with the groove 4 adapted with chip form.
Aluminium alloy heat radiator of the present utility model have employed the endothermic substrate of aluminium alloy, the heat absorption efficiency to chip can be accelerated, fin 2 distributes with spiral dress on endothermic substrate 1, at the middle part of endothermic substrate 1 around formation centre bore, no matter air-flow from what angle is blown over, all can arrive in centre bore 3 by part heat sink 2, form gas channel, therefore, it is possible to strengthen the radiating efficiency of radiator.And the fin 2 of this spiral, along the radial direction of endothermic substrate 1, gap between fin 2 reduces gradually, this structure not easily piles up dust, even if having some dust accretions between fin 2, also clear up very well, only the gap of hairbrush between fin 2 need be used to brush laterally and dust can be cleared up away.And aluminium alloy heat radiator structure of the present utility model is simple, low cost of manufacture, is more convenient for producing and application.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is not when departing from spirit and scope of the present utility model; can also make various conversion and change and obtain corresponding equivalent technical scheme, therefore all equivalent technical schemes all should be included into scope of patent protection of the present utility model.
