1. Technical Field
The disclosure generally relates to electronic devices, and particularly to an electronic device with a spray type heat dissipation.
2. Description of Related Art
Heat dissipation devices, such as a fan and a heat sink are located in an enclosure of an electronic device for dissipating heat. Power consumption and heat from the electronic device increase with the enhancement of performance For satisfying increased heat dissipation demand, a fan with better heat dissipation effect, such as higher rotation speed, or larger blades is required. Fan with higher rotation speed may generate greater noise, and the enclosure of the electronic device has to be enlarged if larger fan is used. Thus, there is a room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
The electronic device 100 includes an enclosure 10, a motherboard 20, a heat sink 30 and a spray device 50. The enclosure 10 includes a bottom cover 12 and a keyboard module 18. An outlet 124 is defined in one side of the bottom cover 12. The motherboard 20 is located between the bottom cover 12 and the keyboard module 18. A plurality of heat generation elements, such as CPU, and memory is located on the motherboard 20. An opening 22 is defined in the enclosure 10.
The heat sink 30 includes a fan 31, a heat pipe 35 and a plurality of fins 34. A first end of the heat pipe 35 contacts the plurality of elements 23, and a second end of the heat pipe 35 contacts the plurality of fins 34.
The water box 51 is substantially cylinder. The water box 51 can contain water, such as pure water, or alcohol.
The pump member 53 includes a press cylinder 532, an inlet pipe 531, an outlet pipe 533, a press pole 535, and a cap 537, and a coil spring 539. The pump member 53 can draw the water to the spray member 55 by pressing down the cap 537. The cap 537 is located on a top portion of the press pole 535. A bottom portion of the press pole 535 extends into the press cylinder 532. The coil spring 539 surrounds the press pole 535, and is located between the cap 537 and the press cylinder 532. A through hole 582 is defined in the baffle 58 for receiving the cap 537. The cap 537 can move through the through hole 582.
The spray member 55 includes a buffering pipe 551, a spray pipe 555, and a connecting pipe 553 connecting the buffering pipe 551 and the spray pipe 555. The buffering pipe 551 connects the outlet pipe 533 of the pump member 53. The outlet pipe 533 engages with the buffering pipe 551 by an interference fit. The buffering pipe 551 is substantially U-shaped for preventing water backflow. The spray pipe 555 and the connecting pipe 553 are substantially straight. The spray pipe 555 is substantially perpendicular to the connecting pipe 553. The spray pipe 555 and the connecting pipe 553 are located in a first plane. The buffering pipe 551 is located in a second plane. The first plane is substantially perpendicular to the second plane. A plurality of nozzles 556 is defined in the spray pipe 555. The plurality of nozzles 556 is evenly spaced.
In use, heat generates from the plurality of the heat generation elements. Airflow extends through the plurality of fins 34 generated from the fan 31. For further dissipating heat from the heat sink 30, the cap 537 is pressed down. The pump member 53 draws water from the water box 51 and outputs the water to the spray member 55. The water extends through the spray member 55 and sprays out through the plurality of nozzles 556. The sprayed water falling onto the plurality of fins 34 can speed up cooling the plurality of heat generation elements. The sprayed water can quickly be blown out of the enclosure 10 through the output 124 by the airflow.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
