Abstract

The utility model discloses a portable PC heat radiation apparatus, comprising a front cover, a back cover, and a metal housing composed of a bottom plate and an outer cover, the internal of the metal housing is provided with a cavity of a main circuit board, the main circuit board provided with a CPU is electrically connected with an expanded circuit board, the expanded circuit board is provided with an expansion interface, a heat sink in a direct contact with the CPU is provided in parallel to and at the upper part of the main circuit board, the heat sink is fixedly provided with a fan. Due to direct contact of the CPU and the heat sink provided with the fan, and the larger heat sink area, heat generated by the CPU can be timely dissipated, heat can be reduced, product stability can be improved, and volume of heat radiation apparatus is smaller.

Description

The portable PC heat abstractor
Technical field
The utility model relates to the heat abstractor field, particularly a kind of portable PC heat abstractor.
Background technology
Along with development of electronic technology, because the portable electric consumers can be brought conveniently to people's life of working, so the portable electric consumers has become a kind of development trend.
All can generate heat during electronic product work, especially for the portable electronic product, because its volume is little; It is more concentrated to generate heat, and therefore usually through the fan forced heat radiation with through the optional heat radiation of heat radiator, the heat dissipation design that adopts like notebook computer all is to adopt heating radiator to add radiator fan; Though the forced heat radiation effect is better, because the heating radiator volume is big and need bigger space accommodate electric fan, further reduced volume; Cause the portable type electronic product volume bigger, does not carry the aspect.
The utility model content
The technical matters that the utility model mainly solves provides a kind of portable PC heat abstractor, and the portable PC volume that said portable PC heat abstractor can avoid heating radiator to cause is excessive, reduces the portable PC volume, is convenient for carrying.
In order to address the above problem; The utility model provides a kind of portable PC heat abstractor, and this portable PC heat abstractor comprises the metal shell of being made up of protecgulum, bonnet and base plate and outer cover, is provided with the cavity of main circuit board in this metal shell; The main circuit board that is provided with CPU is electrically connected with expander board; This expander board is provided with expansion interface, on said main circuit board parallel position, is provided with the heat sink that directly contacts with CPU, is fixed with fan on this heat sink.
Say that further said base plate is provided with louvre at position of fan.
Say further, be covered with air vent after said.
Say that further said outer cover both sides are provided with heat sink strip.
The utility model portable PC heat abstractor; Comprise the metal shell of forming by protecgulum, bonnet and base plate and outer cover; Be provided with the cavity of main circuit board in this metal shell, the main circuit board that is provided with CPU is electrically connected with expander board, and this expander board is provided with expansion interface; On said main circuit board parallel position, be provided with the heat sink that directly contacts with CPU, be fixed with fan on this heat sink.Because CPU directly contacts with the heat sink that is provided with fan, and the heat sink area is bigger, can the heat that CPU produces in time be shed, reduce heat, can improve the stability of product on the one hand, can make the heat abstractor volume less on the other hand.
Description of drawings
Fig. 1 is the utility model portable PC heat abstractor example structure decomposing schematic representation.
Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the utility model purpose is described further.
Embodiment
As shown in Figure 1, the utility model provides a kind of portable PC heat abstractor embodiment.
This portable PC heat abstractor comprises the metal shell of being made up of protecgulum 4, bonnet 3 and base plate 2 and outer cover 1; Be provided with the cavity (accompanying drawing does not indicate) of main circuit board in this metal shell; The main circuit board 7 that is provided with CPU is electrically connected with expander board 6; This expander board 6 is provided with expansion interface, on said main circuit board 7 parallel positions, is provided with the heat sink 8 that directly contacts with CPU, is fixed with fan 9 on this heat sink 8.
Because CPU directly contacts with the heat sink that is provided with fan, and the heat sink area is bigger, can the heat that CPU produces in time be shed, reduce heat, can improve the stability of product on the one hand, can make the heat abstractor volume less on the other hand.
In the present embodiment, said base plate 2 is provided with louvre 21 at fan 9 correspondence positions, can better heat be loose to the outside of shell.Said bonnet 3 is provided with air vent 31, can make to form cross-ventilation in the shell, further improves rate of heat dissipation and imitates.Said outer cover 1 both sides are provided with heat sink strip 11, improve radiating efficiency.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
