Therefore, the notebook computer can be connected with a plurality of accessories or external equipment through the wireless charger.

Referring to fig. 1 to 7, the wireless charger includes a housing 110. The housing 110 may be a plastic member. Thus, the weight of the housing 110 is small. The housing 110 includes housing sidewalls 111, a housing top cover 112, and a housing bottom cover 113. The housing sidewall 111 is a circumferentially continuous frame structure. Thus, the upper end of the frame structure of the housing sidewall 111 has a housing top opening. The lower end of the frame structure of the housing side wall 111 has a housing bottom opening. A housing top cover 112 may be attached to the upper end of the housing side wall 111 and close the housing top opening.

Thus, the partition plate 180, the partition rib 164, part of the outer peripheral wall 161, and part of the charging bottom cover 163 constitute the air outlet flow path 168. The partition rib 164, part of the outer peripheral wall 161, part of the charging top cover 162, and part of the charging bottom cover 163 constitute an air inlet flow passage 165.

The air inlet channel 165 is connected to the air inlet 167. The air outlet channel 168 is connected to the air outlet 166. The charging bottom cover 163 has a charging recess 169 with an opening facing upward. A space is provided between the bottom surface of the charging recess 169 and the partition rib 164. Thus, the inlet duct 165 and the outlet duct 168 communicate with each other through the charging recess 169.

Referring to fig. 2 and 6, the partition rib 164 includes an end rib 211 and two side ribs 212. The end ribs 211 extend in the second horizontal direction Y. The side ribs 212 extend in the first horizontal direction X. The two side ribs 212 are disposed at intervals in the second horizontal direction Y. Thus, the end rib 211 and the two side ribs 212 constitute a C-shaped structure that opens toward the outlet opening 166. Along the second horizontal direction Y, the air outlet 166 is located between the two side ribs 212. Thereby, the structure of the charging case 160 is simple.

Referring to fig. 4 to 6, when the wireless charger operates, air flows through the air inlet 167, the air inlet channel 165, the air outlet channel 168, and the air outlet 166 in sequence under the action of the fan 150.

With continued reference to fig. 4-6, the wireless charger further includes a charging coil 130 and a positioning pole 140. The charging coil 130 and the positioning pole 140 are fixedly attached to the charging cap 162. There is a space between the partition 180 and the charging top cover 162. The charging coil 130 and the positioning pole 140 are both located in the space between the spacer 180 and the charging cap 162. The charging coil 130 and the positioning pole 140 may be attached to the lower surface of the charging top cover 162 (the surface of the charging top cover 162 facing the charging bottom cover 163).

When the mobile phone is placed on the upper surface of the charging top cover 162, the positioning magnetic pole 140 can be precisely aligned with the mobile phone, so that the coil of the mobile phone is aligned with the charging coil 130 of the wireless charger. The charging coil 130 converts the electric energy into electromagnetic waves and transmits the electromagnetic waves to the mobile phone. At the handset, the electromagnetic waves are converted into electrical energy. Thereby charging the cellular phone without connecting the cellular phone and the charger through a wire.

The wireless charger also includes a fan 150. The fan 150 may be a turbo fan 150. The fan 150 is located within the charging housing 160. The fan 150 is used for driving air to flow through the air inlet 167, the air inlet channel 165, the air outlet channel 168 and the air outlet 166 in sequence, so as to dissipate heat of the charging coil 130, the positioning magnetic pole 140, the later charging PCB 190 and the mobile phone.

Preferably, the fan 150 is located within the outlet flow channel 168. Therefore, the structure of the wireless charger is simple.

In the embodiment, the partition plate 180, the partition rib 164, and the outer peripheral wall 161 form the air outlet flow channel 168 communicated with the air outlet 166, and an additional air guide structure is not needed, so that when the wireless charger works, noise generated by blocked air outlet of air flow can be effectively reduced; in addition, the air inlet 167 and the air outlet 166 are both located in the casing groove 114, the air outlet 166 and the air inlet 167 are hidden, the appearance of the wireless charger is attractive, and when the mobile phone is placed on the upper surface of the charging casing 160, the mobile phone shields the air inlet 167 and the air outlet 166.

Preferably, as shown in fig. 3 and 4, when the mobile phone is fixed on the upper surface of the charging housing 160, the air outlet 166 may be opposite to the power supply (e.g. a battery) on the back of the mobile phone, so as to blow air towards the power supply of the mobile phone, thereby dissipating heat from the power supply of the mobile phone.

Preferably, the isolation plate 180 is a heat conductive silicone member made of heat conductive silicone. The heat-conducting silica gel part has certain flexibility, good heat-conducting property and excellent insulating property. In this way, the spacer 180 can fill the gap, and then can play a role of buffering between the charging coil 130 and the fan 150, so that the fixation of the charging coil 130 and the fixation of the fan 150 are firmer.

The separator 180 can transfer heat generated by the charging coil 130 to the fan 150 to dissipate heat from the charging coil 130.

Preferably, returning to fig. 2 to 6, the portion of the outer peripheral wall 161 where the air inlet 167 is provided and the portion where the air outlet 166 is provided are both inclined to the horizontal direction. This can improve the effect of hiding the air inlet 167 and the air outlet 166. In addition, when the mobile phone is fixed on the charging top cover 162, the air inlet 167 and the air outlet 166 can be better shielded.

Preferably, the air inlet 167 is located at one end of the outer peripheral wall 161, and the air outlet 166 is located at the other end of the outer peripheral wall 161 in the first horizontal direction X. Therefore, the air inlet 167 can be far away from the air outlet 166 as much as possible, so as to better radiate heat of the charging coil 130.
