Background

With the increasingly strong demand for miniaturization of communication equipment in the market, wearable portable equipment such as an intelligent wristwatch and the like also integrates more and more functions, such as 4G network, GPS positioning, Beidou positioning, Bluetooth, WiFi and the like. However, due to the limitation of the volume of the small-sized communication equipment, the PCB has small area and large power consumption requirement, and heat concentration in a short time is easily caused; for intelligent equipment with high waterproof grade requirement, as the sealing performance is better, the heat is more difficult to dissipate, when the equipment runs with high power consumption, the temperature of the PCBA is rapidly increased in a short time, the damage to partial components is larger, and particularly when the temperature exceeds the working temperature range of a chip, the operation of the whole system is greatly influenced, and the condition of crash can be caused seriously; but also causes discomfort to the human body due to the rapid rise in local temperature.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a heat abstractor of miniaturized wearable equipment disperses the heat conduction of heat source to other regions of equipment through quick effectively, makes the temperature of whole equipment reach the equilibrium, and increase equipment is to outside radiating area to reduce the risk that the complete machine produced because of local temperature risees too fast, improve personnel simultaneously and use experience.

In order to achieve the above object, the technical solution of the present invention is specifically as follows:

the utility model provides a heat abstractor of wearable equipment of miniaturization, includes procapsid, back casing, mainboard, battery, and the procapsid constitutes the accommodation space with the back casing together, and in mainboard and battery were fixed in the accommodation space side by side, mainboard and battery electricity were connected, still included first graphite flake, and the one end of first graphite flake presss from both sides between back casing and mainboard, and the other end of first graphite flake presss from both sides between back casing and battery.

As a further preferable technical scheme, a shielding cover is further arranged on one surface of the main board close to the rear shell, and heat dissipation silicone grease is injected into the shielding cover.

As a further preferable aspect, an alloy sheet is further embedded inside the front case.

Preferably, the alloy sheet is a magnesium alloy.

Preferably, a display screen is further mounted on an outer side of the front housing.

Preferably, a second graphite sheet is further sandwiched between the front case and the display screen.

As a preferred technical solution, the wearable device is a smart wristwatch.

Compared with the prior art, the beneficial effects of the utility model are that:

the magnesium alloy is embedded in the middle of the front shell by an in-mold injection molding process, so that the heat transfer capacity of the front shell is improved, and then the heat of the front shell is transferred to the display screen by utilizing the high-efficiency heat transfer capacity of the second graphene, so that the display screen can dissipate heat to the surrounding air in a large area; on the other hand, inject heat dissipation silicone grease into the shield cover on the mainboard, make and fill up heat dissipation silicone grease in the shield cover, can make the heat conduct to the shield cover surface fast, reuse first graphite alkene piece leads the heat to the battery and the backshell on next door, the big thermal capacity of battery has both been utilized, the large tracts of land of backshell has been utilized again and has been dispelled the heat, thereby make the heat of complete machine more even, the heat radiating area has also been increased simultaneously, even under the circumstances of equipment high power consumption operation, the heat that the mainboard produced also can lead to equipment everywhere fast, make the mainboard temperature can not rise extremely fast, guarantee its normal high-efficient operation, each position temperature of equipment is more even simultaneously, the user also has better experience when using.

The specific implementation mode is as follows:

examples

As shown in fig. 1, a heat dissipation device for a miniaturized wearable device includes a front case 3, a rear case 5, a main board 1, and a battery 7. The upward facing surface of the component shown in the figures is defined as the front surface and the downward facing surface as the back surface thereof. The main board 1 is assembled on the front case 3, and the main board 1 is a main heat source. As shown in fig. 2, the front case 3 is composed of an alloy sheet 9 (magnesium alloy) and a plastic 10, and the combination of the two is formed by an in-mold injection molding process.

Wherein the reverse side of mainboard 1 contacts with alloy piece 9 openly, and after the mainboard produced the heat, can give alloy piece 9 with heat fast transfer, because the heat-conducting capacity of alloy is relatively better, the heat distributes relatively more evenly on preceding casing 3.

Display screen 4 assembles in the procapsid 3 back, still pastes second graphite flake 8 between display screen 4 and procapsid 3, and the good heat transfer performance of usable graphite flake conducts the heat of procapsid 3 to display screen 4, and display screen 4 can be large-area dispel the heat to the air all around.
