Example 1
Referring to fig. 1, fig. 1 is a schematic structural diagram of a heat sink 100. The present embodiment provides a heat sink 100, which mainly includes a semiconductor cooling plate 102. The heat sink 100 may be used to dissipate heat of a general digital device (e.g., a mobile phone, a tablet, a game machine, etc.). The cold side (not shown) of the semiconductor cooling plate 102 is adjacent to the digital device to cool the digital device quickly.
Digital equipment such as mobile phones and tablets is an indispensable part of people's work, study and life. When a user uses the mobile phone for a long time, particularly in summer, the mobile phone can generate heat continuously, and the mobile phone can be damaged greatly due to the continuous high temperature: the battery life is shortened, the system operation is blocked, the internal circuit is possibly damaged, the CPU performance is influenced, and even the mobile phone is forced to be shut down. If the mobile phone is naturally cooled, the waiting time is long, and the use of the mobile phone is limited during the waiting time, which is inconvenient. If the mobile phone is not seen to be hot and used continuously, the service life of the mobile phone battery can be seriously shortened, and the mobile phone can become stuck, and even the mobile phone circuit can be damaged and safety accidents can be caused in serious cases.
The radiator 100 is used in combination with a digital device, so that the temperature of the digital device can be reduced very quickly and efficiently, and the problems of component damage, unsmooth operation and the like caused by overhigh temperature are avoided.
In this embodiment, the heat sink 100 mainly uses the semiconductor cooling plate 102 to cool and dissipate heat of the digital device. The semiconductor refrigerating chip is also called refrigerating chip or thermoelectric refrigerating chip, and utilizes the Peltier effect of semiconductor material (the Peltier effect means that when current passes through the loop formed from different conductors, the irreversible Joule heat is produced, and the heat absorption and heat release phenomena can be respectively produced at the joints of different conductors along with the difference of current direction), so as to implement the goal of refrigeration. The refrigerating plate has the advantages of high refrigerating speed, capability of continuously working, no moving assembly and low working noise, and is suitable for occasions with limited space, high reliability requirement and no refrigerant pollution. And the refrigerating sheet can realize high-precision temperature control by controlling the magnitude of the input current.
In this embodiment, the heat sink 100 may further include a bottom plate 104. The bottom plate 104 may provide a support and mounting platform for various components of the heat sink 100, and also facilitate later sale of the heat sink 100 as a single unit. Of course, in other embodiments, the bottom plate 104 may not be provided, and after the heat sink 100 is sold, the user finds a corresponding mounting position on the digital device by himself to mount the heat sink 100.
Referring to fig. 2, fig. 2 is a schematic structural diagram of the bottom plate 104. In this embodiment, the bottom plate 104 is provided with a first through hole 105, and the shape of the first through hole 105 matches with the shape of the semiconductor chilling plate 102. After the semiconductor cooling plate 102 penetrates through the first through hole 105, the cooling surface of the semiconductor cooling plate 102 is adjacent to the digital device (may be in a direct contact state, or may be in a close state with a certain distance), so as to cool and dissipate heat of the digital device.
Please refer to fig. 1 again. In this embodiment, the heat sink 100 further includes a heat dissipating member 106 and a fan 108. The heat dissipation member 106 is provided with a recess (not shown), the fan 108 is an embedded fan, and the fan 108 is mounted in the recess of the heat dissipation member 106 (in other embodiments, the heat dissipation member 106 may not be provided with a recess, and accordingly, the fan 108 may not be an embedded fan, and the fan 108 is mounted on the heat dissipation member 106). The concave part can enlarge the contact area between the heat dissipation member 106 and the air, thereby accelerating the heat transfer rate between the air and the heat dissipation member 106 and enhancing the heat dissipation effect. The concave part is matched with the embedded fan, so that the size and the occupied space of the radiator 100 can be greatly reduced, the portability is higher, and the user experience is good. The side of the heat sink 106 remote from the fan 108 is connected to the hot side (not shown) of the semiconductor cooling plate 102. The heat dissipation member 106 and the fan 108 cool and dissipate the hot surface of the semiconductor cooling plate 102 together, so as to avoid the adverse effect on the digital equipment caused by the overhigh temperature of the hot surface of the semiconductor cooling plate 102. In other embodiments, the heat sink 100 may also adopt other arrangements to cool and dissipate the hot surface of the semiconductor cooling plate 102, such as a heat pipe, as long as the heat of the hot surface of the semiconductor cooling plate 102 can be taken away, so as to avoid damage to each component due to high temperature.
In this embodiment, the semiconductor chilling plate 102 adopts a double-layer semiconductor chilling plate, and the chilling effect is more remarkable. In other embodiments, the semiconductor chilling plate 102 may also adopt a single-layer chilling plate, a plurality of multi-layer chilling plates with the rest number, or a structure formed by stacking a plurality of single-layer chilling plates, as long as the function of quickly cooling and dissipating heat of the digital device can be achieved.
In this embodiment, the hot surface and the cold surface of the semiconductor cooling plate 102 are coated with a heat conductive silicone layer (not shown). The heat-conducting silica gel has excellent cold and heat alternation resistance, aging resistance and electrical insulation performance, and has excellent moisture resistance, shock resistance, corona resistance, electric leakage resistance and chemical medium resistance. The existence of the heat-conducting silica gel layer can reduce the influence of air on heat conduction to the maximum extent, so that the cold surface of the semiconductor refrigeration piece 102 can quickly and effectively reduce the temperature of the digital equipment. Meanwhile, the heat of the hot surface of the semiconductor cooling plate 102 can be quickly transferred to the heat dissipation member 106, and then the temperature is dissipated to the outside air through the fan 108, so that the temperature of the hot surface of the semiconductor cooling plate 102 is reduced. And the heat-conducting silica gel has certain viscosity, so that the cold surface of the semiconductor refrigeration piece 102 can be better contacted with digital equipment, and the hot surface of the semiconductor refrigeration piece 102 is better connected with the heat dissipation piece 106. In other embodiments, other heat conducting devices such as heat conducting silicon tape can be used for the cold side and the hot side of the semiconductor cooling plate 102, as long as they have good heat conducting performance and electrical insulating performance.
In this embodiment, the heat sink 100 may further include an electric control portion 110. The electric control unit 110 is mounted on the base plate 104.

The controller 116 regulates and controls the rotation speed of the fan 108 and the power of the semiconductor chilling plate 102 at the same time according to the gear of the adjusting switch 118, so that the rotation speed of the fan 108 can be always matched with the power of the semiconductor chilling plate 102 (for example, when the chilling power of the semiconductor chilling plate 102 is 1 watt, the rotation speed of the fan 108 is 3000 revolutions per minute), heat dissipation can be performed on the hot surface of the semiconductor chilling plate 102 in time, meanwhile, the radiator 100 can be suitable for digital equipment with different models and powers, and the energy is utilized more reasonably. It should be noted that in other embodiments, the fan 108 and the semiconductor cooling plate 102 can be adjusted by different switches, but this may result in more switches, which may reduce the hand-holding comfort of the user when the user uses the digital device with the heat sink 100 installed therein. Meanwhile, the fan 108 and the semiconductor chilling plate 102 are respectively adjusted through different switches, a user cannot make a correct judgment on which power the fan 108 at which rotating speed should be matched with the semiconductor chilling plate 102, and after adjustment, the hidden danger that the rotating speed of the fan 108 is low and heat emitted from the hot surface of the semiconductor chilling plate 102 cannot be taken away in time may exist, so that heat accumulation and temperature rise are finally caused, and damage is caused to the digital equipment and the radiator 100.
The first electrical connector 112 is used for connecting an external power source, thereby providing power to the heat sink 100. Second electricity connects 114 can utilize external charging wire and digital equipment electric connection to charge for digital equipment, promote user experience.
In other embodiments, the electric control unit 110 may further include an electric storage unit, and the electric storage unit may be rechargeable (in which case, the electric control unit 110 may be provided with the first electric connector 112) or non-rechargeable (in which case, the electric control unit 110 may not be provided with the first electric connector 112). As long as it can supply power to the heat sink 100 and charge the digital device.

The model number may be Siemens brand S7-200CN, which is convenient for commercial purchase. In other embodiments, the controller 116 may adopt other types of PLC control systems, or may adopt a single chip microcomputer, as long as it can control the operating states of the semiconductor cooling fins 102 and the fan 108.

The third electric connector 122 can be electrically connected with the digital device through an external data line, and the sound box 120 can receive the audio signal of the digital device and play the audio signal under the control of the controller 116, so that the use experience of a user is improved. In other embodiments, the audio output device in other modes, such as bluetooth audio (when bluetooth audio is used, the third electrical connector 122 may not be provided), may be used as the audio output device 120, as long as the function of receiving and outputting the audio signal of the digital device can be completed.
Referring to fig. 1 and 3, fig. 3 is a schematic structural diagram of the protective cover 124. In this embodiment, the heat sink 100 further includes a protective cover 124. The protective cover 124 is fastened to the base plate 104 (in other embodiments, the protective cover 124 and the base plate 104 may be connected by other detachable connection methods such as bolt connection, or may be connected by fixed connection methods such as welding and bonding, as long as the protective cover 124 can be fixed to the base plate 104, so that the protective cover 124 can protect the components in the protective cover 124). The heat sink 106, the fan 108, the controller 116, and the audio 120 are all located within a protective enclosure 124, and the first electrical connector 112, the second electrical connector 114, the adjustment switch 118, and the third electrical connector 122 are all located outside the protective enclosure 124. The protective cover 124 can provide protection for the components in the cover, and reduce the interference of external factors on the components in the cover; meanwhile, the user can be prevented from directly contacting the heat dissipation member 106, the fan 108 and other components, and the user is prevented from being injured.
In this embodiment, a plurality of vents 125 are disposed on the shield 124 in the area corresponding to the fan 108. The ventilation holes 125 serve as a passage for discharging hot air blown by the fan 108 to the outside of the shield 124, and provide a passage for outside air to enter the shield 124, so that air with a low outside temperature can enter the shield 124 for cooling.
In this embodiment, two elastic members 126 are symmetrically disposed between the side of the heat dissipation member 106 away from the semiconductor cooling plate 102 and the protective cover 124 (in other embodiments, the number of the elastic members 126 may be one, or three or more, as long as the heat dissipation member 106 can receive a force in a direction away from the protective cover 124 and the force is balanced).
