Description

Power supply adaptor

Technical field

The present invention relates to the design field of power supply adaptor, particularly relate to the heat radiation structure design of power supply adaptor.

Background technology

For whole notebook computer, the importance of power supply is absolutely not low than CPU, and what the stable operation of whole notebook computer depended on that power supply continues provides stable magnitude of voltage.Because notebook computer generally adopts direct supply to drive, and the power supply normally AC power that user adopts, as China adopts the alternating current of 220 volts, therefore notebook computer can be equipped with a power supply adaptor usually.The basic functional principle of power supply adaptor High Level AC Voltage (alternating currents as 220 volts) is converted to low-voltage DC needed for notebook computer by high-frequency switching technology.In alternating current and galvanic transfer process, due to the restriction of state-of-the art and the characteristic of electronic devices and components itself, the energy some becomes heat energy, distributes among air with the form of heat, and it gives the sensation of high temperature.In addition, power supply adaptor work in the case of a high temperature can comparatively under normal temperature serviceability reduce to some extent, be mainly reflected in output power and reduce.

Because the integrated level of electronic devices and components is more and more higher, function is also more and more stronger, the physical dimension of the electronic equipment originally taking larger space is reduced with the form of the order of magnitude, but the thermal value of unit volume is in increase.In visible electronic devices and components miniaturization, integrated process, its heat dissipation problem highlights.As a rule, the operating temperature range of electronic devices and components is between-5 ~ 65 degree.When temperature exceedes above-mentioned scope, the degree of accuracy of electronic devices and components, degree of stability, also have the performances such as the resistance of all kinds of electronic component, capacitance and inductance value all will significantly to decline, even cannot steady operation, affects whole system reliability of operation the most at last.Some electronic component of power supply adaptor also can be made under individual cases to damage, cause the mistake of power supply adaptor to damage.

In summary, the heat dissipation problem of power supply adaptor has become a bottleneck in power supply adaptor design gradually.

Summary of the invention

The object of the invention is to the defect overcoming prior art, aim to provide the power supply adaptor with better heat dispersion.

The present invention realizes like this, power supply adaptor, comprise housing, described housing has the chamber of collecting circuit board, the surface of described housing is provided with the pin of external power supply, one or more secondary cavities that described chamber comprises main chamber and extended by described main chamber, described main chamber and each described secondary cavity are interconnected; Described circuit board comprises the main board be arranged in described main chamber and the subplate being arranged at secondary cavity.

Particularly, described housing comprises drain pan and is fastened on the upper cover on described drain pan, and described upper cover has one or more half the circumference of the sleeve where it joins the shoulder, and described half the circumference of the sleeve where it joins the shoulder has cavity.

Particularly, described secondary cavity is provided with two, and described secondary cavity is made up of the both sides extension of described main chamber.

Particularly, connected by the rebound of an arc between half the circumference of the sleeve where it joins the shoulder described in adjacent two.

Particularly, described rebound is provided with radiating fin.

Particularly, described half the circumference of the sleeve where it joins the shoulder symmetry be arranged at described upper cover both sides, and the cross section of described upper cover is M shape.

Particularly, this power supply adaptor also comprises the electric power connection line of being drawn by described housing, the projection that the two ends of each described half the circumference of the sleeve where it joins the shoulder are provided with.
