Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
What the present invention proposed is a kind of air-cooled radiating device of forced air convection and heat dissipating method of this device of adopting, and its core is kept apart the inner space of cross-ventilated passage and equipment 12 to form independently convection current air channel.By the heat conduction of equipment 12 inner heat generating components on thermal component, can pass on thermal component by the mode of conduction, also can by other means (such as convection current), emphasis is first delivered on thermal component by heat.In addition, the equipment 12 in the present invention does not limit, and it can be any electronics, electric equipments needing wind-cooling heat dissipating such as computer.Specifically, air channel comprises air channel body 1, and air channel body 1 is arranged in equipment 12, and air channel body and device interior electronic device are isolated.In the body of air channel, offer air-inlet cavity 2 and air-out chamber 3, air-inlet cavity 2 and air-out chamber 3 are arranged in the body of air channel all completely.Air-inlet cavity 2 comprises relative first end 4 and the second end 5, air-out chamber 3 comprises the 3rd relative end 6 and the 4th end 7, and equipment arranged outside has air inlet 8 and air outlet 9, and first end 4 connects with air inlet 8, second end 5 and the 3rd end 6 mutually through, the 4th end 7 connects with air outlet 9; Therefore, air-inlet cavity and air-out chamber just constitute a complete air channel.It is pointed out that first end, the second end, the 3rd end and the 4th end are all arranged in the body of air channel.Although the second end and the 3rd end mutually through, be also be positioned at air channel body.Because air-inlet cavity and air-out chamber are the structure of heat sinking function, air-inlet cavity and air-out chamber are designed inner in air channel, the air of forced convertion is from device external, air-out chamber is imported into after air-inlet cavity, behind air-out chamber, get back to device external again, complete heat exchange like this, air only passes through in independently inside, air channel, access arrangement is inner, this avoid device interior directly and outside air generation convection current.
Further, in order to strengthen radiating effect, can be provided with radiator fan 10 in air-out chamber, air-inlet cavity and air-out chamber are provided with heat radiation gear piece, and heat radiation gear piece is for strengthening radiating effect.Because air-inlet cavity and air-out chamber constitute a complete air channel, the gear piece that therefore dispels the heat can be distributed in whole air channel.In addition, the present invention does not limit material, shape, the size of air-inlet cavity, air-out chamber, heat radiation gear piece.Install fan additional in heat sink interior, accelerate air flowing thus increase radiating effect.Dust in extraneous air, can only flow in heat abstractor, can not access arrangement inside.
As the application mode of heat abstractor of the present invention, in order to realize best radiating effect, the heating electronic device of device interior, as the heater members such as CPU, power supply 13 is directly attached to the outer wall of air channel body 1.As shown in Fig. 6, Fig. 7, Fig. 8.What in figure, upper dotted line frame table reached is heater members 13, emphasizes it is overleaf, not in front with dotted line.Under this mode, the heat that heater members 13 sends is by direct contact the with air channel body 1 outer wall, the heat conduction produced is to air channel body 1, and heat is outputted to device external by entering the intrinsic convected air in air channel by heat that air channel body 1 obtains again.In this process, the electronic device in convected air and equipment is mutually isolated, avoids dust inner by convected air access arrangement.
The alternatively application mode of heat abstractor of the present invention, the efficient heat-transfer devices such as heat pipe can be increased, heat-transfer device one end and heater members 13 contact with each other, and the heat-transfer device other end contacts with air channel body outer wall, are transmitted to air channel body 1 by heat by heat-transfer device from heater members 13.Heat is outputted to device external by entering the intrinsic convected air in air channel by heat that air channel body 1 obtains again.
Shown below is the heat dissipating method of this air duct heat dissipating device 14, comprise the steps:
Step one: first sensor device interior state of temperature is set;
Step 2: controller receives the signal of first sensor, and open according to temperature regime or close fan, and adjust rotation speed of the fan when fan opening.
It is pointed out that the setting of transducer is here to better realize radiating effect.As long as have controlling functions for the fan of forced air convection, just can carry out the rotating speed of classification adjustment fan according to the temperature conditions of device interior, classification comprises can close fan completely.The method of controller can be added with transducer, also simply can use temperature detect switch (TDS).
The internal state of equipment can be the frequency of the electronic building brick in the utilization rate of the electronic building brick in the processing speed of the electronic building brick in the temperature in equipment, the temperature of the electronic building brick in equipment, equipment, equipment or equipment.The external status of equipment can be the mode of operation of input unit, the state of the image sensed of video camera or object whether near the state of electronic installation.Difference along with product design is come the internal state of define equipment and external status and is selected the first sensor of arranging in pairs or groups according to internal state and external status.The equipment that the present invention uses can be a notebook computer, desktop computer or arbitrary intelligent processing system.Controller of the present invention can be embedded controller or the independently processor in notebook computer.In addition, electronic building brick of the present invention can be a display chip of equipment, a control chip or a central processing unit.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry answers described understanding, and above-described embodiment does not limit the present invention in any form, and the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains all drops in protection scope of the present invention.
