Description

[0001] The utility model relates to the technical field of radiator structures, in particular to a radiator suitable for a wireless charging module. Background Art

[0002] In the wireless charging module, the existing fans are all arranged on the outside of the radiator body. An air duct is arranged inside the radiator body, and then the heat contacted by the radiator body is blown away along the air duct by the fan to form an air cooling operation.

[0033] A heat sink suitable for wireless charging module, see Figure 1-Figure 4 , which includes: a base 10, an upper cover 20, a fan bracket 30, and a turbine fan 40.

[0034] During specific implementation, the base 10 and the upper cover 20 are both square, quasi-square, rectangular or quasi-rectangular structures when viewed from above; for ease of distinction, in a specific embodiment, the base 10 and the upper cover 20 are both rectangular structures when viewed from above, the air ducts corresponding to the long sides are the air inlet ducts, and the air ducts corresponding to the short sides are the air outlet ducts.

[0035] The base 10 includes a central concave fan placement cavity 11 on the upper layer of the surface area. The fan placement cavity 11 is a double-layer structure. The upper layer of the fan placement cavity 11 is used to place the turbine fan 40, and the lower layer is used for the inflow of airflow. The periphery of the fan placement cavity 11 forms a cross air duct. One group of cross air ducts formed by the air ducts at both ends of the same straight line is the upper air outlet air duct 12, and the other group of cross air ducts formed by the air ducts at both ends of the same straight line is the lower air inlet air duct 13. The upper layer of the fan placement cavity 11 and the corresponding air inlets of the upper air outlet air duct 12 are at the same height position, and the lower layer of the fan placement cavity 11 and the air outlet of the lower air inlet air duct 13 are at the same height position;

[0036] The fan support 30 includes an inner end fan placement end 31 and an outer end flow channel composition frame 32;

[0037] The turbine fan 40 takes in air from the bottom and then rotates through the upper impeller 41 to discharge air.

[0038] The upper layer of one of the lower air inlet ducts 13 of the cross duct is an inner concave notch groove 14, which is used to place the outer end flow channel component frame 32. A plurality of groups of sinking flow channel plates 141 are arranged at the lower inner end of the inner concave notch groove 14. The outer end flow channel component frame 32 guides the wind to the air duct area corresponding to the sinking flow channel plate 41, and the outlet area of ​​the sinking flow channel plate 41 is connected to the lower layer of the fan placement chamber 11;

[0039] The inner fan placement end 31 is used to fix the turbine fan 40 , and a bottom plate 312 of the inner fan placement end 31 is provided with an avoidance gap 311 corresponding to the air inlet of the turbine fan 40 .

[0040] During specific implementation, the upper cover 20 is installed on the upper surface of the base 10 and the fan bracket 30, and the turbine fan 40 is placed on the inner end fan placement end 31 to form a pull-out assembly structure.

[0041] In a specific embodiment, the upper cover 20 is a single cover or a functional cover with a charging and transmitting coil attached, which can be set according to the situation;

[0042] A first baffle 15 is provided at the lower part of the air inlet of the upper air outlet duct 12. The first baffle 15 and the bottom plate 312 of the inner fan placement end 31 are combined to seal the lower air in the lower flow channel, so that the air in the lower flow channel can only enter the turbine fan 40 through the avoidance gap 311.

[0043] The lower end of the first partition plate 15 is provided with an inwardly concave arc structure 151 corresponding to the flow wind area of ​​the lower air duct. The inwardly concave arc structure 151 reduces the wind resistance of the lower air duct and increases the heat exchange air volume.

[0044] A second partition plate 16 is provided on the upper layer of the other lower air inlet duct 13 corresponding to the air outlet, and the second partition plate 16 ensures that the upper wind in the fan placement chamber 11 cannot be connected to the lower air inlet duct 13;

[0045] The outer end flow channel component frame 32 includes a first air inlet mesh plate 321, a connecting rod 322, and a second stop plate 323. The first air inlet mesh plate 321 is arranged with a plurality of groups of air inlet holes.

The second stop plate 323 is used to isolate the air inlet and air outlet ducts.

[0046] The second stop plate 323 is arranged just above the inner end of the sinking flow channel plate 141. The wind coming in along the flow channel of the outer end flow channel forming the frame is blocked by the second stop plate 323 and then passes through the plurality of flow channels of the sinking flow channel plate 141 into the lower layer of the fan placement chamber 11.

[0047] A first air outlet mesh plate 121 is disposed on the upper outer side of the base 10 corresponding to the upper air outlet duct 12. A plurality of air outlet holes are arranged on the first air outlet mesh plate 121. The air outlet holes are evenly arranged along the air outlet of the upper air outlet duct 12.

[0048] A plurality of first flow channel plates 122 are arranged in the upper air outlet duct 12. The first flow channel plates 122 are arranged in sequence along the width direction of the flow channel, so that the wind is discharged from the inside to the outside.

[0049] A second air inlet mesh plate 131 is disposed on the outer side of the upper layer of the base 10 corresponding to another lower air inlet duct 13, and a plurality of groups of air inlet holes are arranged on the second air inlet mesh plate 131, and the air inlet holes are evenly arranged along the upper air inlet of the lower air inlet duct 13;

[0050] A plurality of groups of second flow channel plates 132 are arranged in another lower air inlet duct 13. The second flow channel plates 132 are arranged in sequence and at intervals along the width direction of the flow channel so that the wind flows in from the outside to the inside.

[0051] The second partition 16 is provided with an energized docking interface 1, and a docking socket 2 is provided at a position where the inner end fan placement 31 faces the second partition. After the turbine fan 40 is assembled in place, the docking socket 2 is plugged into the docking interface 1 to complete the electrical connection, which makes the installation quick and convenient. In specific implementation, the docking interface 1 and the docking socket 2 are male and female docking structures.

[0052] In specific implementation, the first flow channel plate 122 and the second flow channel plate 132 are flow channel plates of the same thickness, which are suitable for both upper layer circulation and lower layer circulation. Different air channels are set only by setting different positions of the inner end partitions.

[0053] Its working principle is as follows: the turbine fan is fixedly installed at the fan placement end at the inner end of the fan bracket, and the fan bracket is installed through the concave notch groove, so that the turbine fan is located in the upper layer of the concave fan placement cavity, and the lower surface of the base is used for absorbing heat and dissipating heat, and the external wind is integrated into the lower layer of the fan placement cavity along the outer air inlet of the lower air inlet duct, and then is sucked in by the air inlet of the turbine fan, and then is discharged into the outer periphery of the fan blades of the upper layer of the fan placement cavity through the rotation of the fan blades, and then the hot air is discharged along the upper air outlet duct, and the air cooling operation is repeated over and over again; since the fan is built into the radiator, the area occupied by the entire radiator is relatively small, and the space requirement for installation is small, and since the turbine fan is in the central area of ​​the air inlet duct and the air outlet duct, it can reliably blow stable airflow from the duct inlet to the duct outlet during air flow transmission, so that the surface heat dissipation of the radiator body is uniform.

[0054] The pull-out assembly mechanism composed of the fan bracket and the turbine fan can repair and replace the wearing parts (fan) without changing the overall structure, which is beneficial to improving the maintainability and life of the whole machine.
