Description

A kind of mobile phone cooling protective cover

technical field

The invention relates to a protective cover, in particular to a heat dissipation protective cover for a mobile phone.

Background technique

At present, the mobile phone has become a necessity of people's life, and the heat dissipation performance of the mobile phone protective cover directly affects the user experience. However, the mobile phone protective cases on the market seriously hinder heat dissipation. When talking for a long time, watching movies, or playing games, a lot of heat and radiation will be generated, which will affect the life of the whole phone and cause radiation to the human body.

Most of the existing mobile phone protective cases that can dissipate heat are passive heat dissipation, and the heat dissipation is enhanced by improving the thermal conductivity of the material, but the heat dissipation effect is poor, and the heat dissipation cannot be automatically adjusted according to the user's usage; there are also some active heat dissipation mobile phone cases, Heat dissipation through an external device, although the heat dissipation effect is good, it will consume energy and generate noise, and the versatility is poor, so it cannot be mass-produced and applied to various types of mobile phones. Moreover, whether it is passive heat dissipation or active heat dissipation, the mobile phone protective cover will generate heat when dissipating heat, which will increase the radiation to the human body.

Therefore, it is necessary to urgently provide a novel mobile phone heat dissipation protective cover to solve the above problems.

Contents of the invention

Aiming at the deficiencies in the prior art above, the present invention provides a novel mobile phone heat dissipation protective cover, which has excellent heat dissipation effect and strong versatility, and can automatically adjust the heat dissipation according to the usage situation, and also overcomes energy consumption, noise generation, and mobile phone protective cover. Fever increases the disadvantage of radiation to the human body.

The invention discloses a mobile phone heat dissipation protective cover, a speaker-driven refrigeration device embedded in the mobile phone case provided with grooves, an outer cover is placed on the top of the mobile phone case provided with grooves, and a resonant tube is arranged at one end of the speaker-driven refrigeration device and loudspeaker, a hot-end heat exchanger, a plate stack, and a cold-end heat exchanger are set in the middle of the speaker-driven cooling device, and a buffer cavity is set at the other end of the loudspeaker-driven cooling device, and the thermoelectric sheet is attached to the hot-end heat exchanger, and the speaker and The thermoelectric generator is connected, and the electricity generated by the thermoelectric generator is used for the speaker. The invention adopts an active heat dissipation mode, and has a good heat dissipation and cooling effect.

The outer cover of the mobile phone heat dissipation protective cover can be opened, and the cooling device driven by the loudspeaker inside can be replaced. The speaker-driven cooling unit can be mass-produced and placed in various models of mobile phone cases.

The loudspeaker-driven refrigeration device included in the mobile phone heat dissipation protective cover is based on the principle of thermoacoustic refrigeration, using standing waves generated by the outside world and the sound generated by the mobile phone itself to enter the speaker to cool down the mobile phone, so that noise can be reduced, and the phone can also be cooled during calls. It can reduce the interference of the external environment and ensure the quality of the call.

The thermoelectric power generation sheet included in the mobile phone heat dissipation protection cover is closely attached to the heat exchanger at the hot end, and most of the heat discharged from the heat exchanger is absorbed by the thermoelectric generation sheet, and only a small part is excluded from the mobile phone protective case, which can reduce the heat loss of the mobile phone protective case. Heat, thereby reducing the radiation to the human body.

The thermoelectric generating sheet included in the mobile phone heat dissipation protective cover is connected with the loudspeaker. The heat absorbed by the thermoelectric plates is converted into electricity to power the speakers. In this way, no external power supply is needed, energy consumption is saved, and negative feedback regulation is formed to realize automatic control. The greater the heat dissipation of the mobile phone, the more heat absorbed by the thermoelectric power generation sheet, the greater the current converted, the better the amplification effect, and the greater the cooling capacity generated. On the contrary, the cooling capacity is reduced.

The beneficial effects of the present invention are: the back cover of the mobile phone case of the present invention can be opened, the cooling effect is good, compact, convenient, and practical, and can be applied to various types of mobile phones; the principle of thermoacoustic cooling can absorb external sound cooling, which can absorb Noise, it can reduce the interference of noise to the call during the call; most of the heat is absorbed by the thermoelectric power generation sheet, and only a small part of the heat is discharged to the outside, thereby reducing the heat generation and thermal radiation of the mobile phone protective case on people; the cooling capacity can be automatically adjusted , to meet the different needs of mobile phones for heat dissipation under different uses.

In the invention, the thermoelectric generating sheet is pasted on the heat exchanger at the hot end and connected with the loudspeaker, so that the exhausted waste heat can be absorbed by the thermoelectric generating sheet and transformed into electric energy for power supply of the loudspeaker. This is a negative feedback adjustment, which can automatically control the strength of heat dissipation, save the external power supply, and also discharge waste heat to make the mobile phone protective case heat up, increasing the radiation to the human body. The invention is a novel mobile phone heat dissipation protective cover capable of maintaining the temperature of the mobile phone at a normal level for a long time.

Referring to Fig. 1 and Fig. 2, the present invention provides a new type of mobile phone heat dissipation protection case, which includes a mobile phone case 3 with a groove for placing a speaker-driven cooling device 2 . The cell phone camera in the groove is provided with a raised reserved hole 4. There is also an outer cover 1, and the outer cover 1 is provided with a reserved hole 5 matched with the raised reserved hole 4 to ensure that photos are taken normally. Mesh holes 6 are also provided on the outer cover 1 to facilitate the entry of external sound into the speaker 7 and the discharge of a small amount of heat from the heat exchanger 8 at the hot end. The outer cover 1 can be opened, and the cooling device 2 driven by the speaker inside can be replaced. The speaker-driven cooling unit 2 is small enough to be mass-produced and placed inside various models of mobile phone cases.

Referring to Fig. 2, a resonant tube and a speaker are arranged at one end of the speaker-driven refrigeration device, a hot-end heat exchanger, a plate stack, and a cold-end heat exchanger are arranged in the middle of the speaker-driven refrigeration device, and the other end of the speaker-driven refrigeration device is arranged In the buffer cavity, the external sound is amplified through the speaker 7, and a stable standing wave is obtained, and the standing wave enters the plate stack 9. Using the principle of thermoacoustic cooling, the heat emitted by the mobile phone inside the mobile phone case is transmitted to the Hot end heat exchanger 8. At this time, the thermoelectric power generation sheet 12 attached to the heat exchanger at the hot end will absorb this part of the heat, convert it into electric energy and connect it to the speaker 7 through the circuit, and perform negative feedback adjustment, thereby realizing automatic control, that is, the greater the heat dissipation of the mobile phone, the greater the heat dissipation. The more heat absorbed by the thermoelectric generation sheet 12, the greater the converted current, the better the amplification effect, and the greater the cooling capacity generated. On the contrary, the cooling capacity is reduced.
