Abstract:
An electronic device includes an accommodating space, a fan, a cover, and a stereoscopic dust extraction mesh. The fan is disposed in the accommodating space. The fan includes a first fixing portion. The cover detachably covers the accommodating space, and the cover includes a second fixing portion in accommodating space. The stereoscopic dust extraction mesh includes a body, a third fixing portion, and a fourth fixing portion, and the third fixing portion and the fourth fixing portion are located at periphery of the body. The third fixing portion of the stereoscopic dust extraction mesh cooperates with the first fixing portion of the fan, and the fourth fixing portion of the stereoscopic dust extraction mesh cooperates with the second fixing portion of the cover to detachably fix the stereoscopic dust extraction mesh between the cover and the fan.
Abstract:
A backlight module including a light guide plate and a light source is provided. The light guide plate has a light incident surface, a light reflection surface, a first side surface and a second side surface. The light incident surface is connected to the second side surface. The reflection surface is connected between the first side surface and the light incident surface. The first and the second side surfaces are two planes with their extending planes intersected. The light incident surface is a chamfering plane connected between the first and the second side surfaces. The light reflection surface is a cambered surface connected between the first side surface and the light incident surface. The light source is disposed next to the light incident surface, so as to transmit light into the light guide plate through the light incident surface.
Abstract:
A heat dissipating device includes a supporting part, a plurality of first fins and a plurality of second fins. The first fins are disposed in a vertical array at the supporting part. The second fins are disposed in an inclined array at the supporting part. The first fins and the second fins are staggeredly disposed and adjacent to each other correspondingly. The heat exchange efficiency of the fins is improved so as to increase the heat dissipating efficiency of the heat dissipating device.
Abstract:
A circuit board includes a main body, an electronic component, a fixing portion and at least one via hole. The electronic component and the fixing portion are disposed on the main body. The at least one via hole is formed on the main body and adjacent to the fixing portion.
Abstract:
An aluminum extruded fin set includes a substrate and a plurality of dissipation fins mounted upright on it. There are gaps between heat dissipation fins. Each dissipation fin is divided into three child dissipation fins by two slanted cutouts. The child dissipation fin between two slanted cutouts is bent toward the gap between heat dissipation fins. When airflow passes by the gaps, the airflow velocity distribution is modified due to the bent child dissipation fins and the noise spectrum distribution is modified as well. Such a Hay-stack noise spectrum distribution is more comfortable for the listener than a conventional one.
Abstract:
The invention provides a heat-dissipation device and a heat-dissipation method thereof. The electronic device includes a heat source, a thermal interface material (TIM) in contact with the heat source, a heat-dissipation module in contact with the thermal interface material, and an elastic member pushing the heat-dissipation module toward the heat source. The elastic member includes a base and a compressible portion extending from the base, whereby a force, applied to the compressible portion, is transmitted to and uniformly distributed on the base. The heat-dissipation method includes the steps of overlapping a thermal interface material and a heat-dissipation module on the heat source, and exerting a force toward the heat source to the heat-dissipation module.
Abstract:
An extended fin array has a main heat-dissipation module and an extended heat-dissipation module. The main heat-dissipation module and the extended heat-dissipation module are stacked to increase the effective convective area to increase the heat-dissipation effect. The extended heat-dissipation module is in the main heat-dissipation module when the heat amount generated by an electronic device is normal. The extended heat-dissipation module extends out from the main heat-dissipation module to increase the heat convection area when the heat amount generated by the electronic device is large.
