The single air channel technology is adopted inside, which mainly conducts the heat of the cooling plate in the hair removal device through the hot copper tube, and then discharges the heat through the airflow and the cooling fins. The heat dissipation of the lamp tube in the hair removal device is completed by the cooling plate. When used for a long time, it is easy to have untimely heat dissipation, which affects the use of the hair removal device and even the service life of the product. In response to the above defects, this application is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide a dual-duct heat dissipation module and a hair removal device, which solves the problem of untimely heat dissipation and difficulty in further improving heat dissipation efficiency caused by traditional single-duct heat dissipation.

The airflow generated by the fan is discharged from the air outlet through air duct one and air duct two. The radiator is provided with cooling fins, and the cooling fins are located in air duct one. The air duct two is used to dissipate heat for the lamp tube in the hair removal device.

[0005] Through the dual-channel setting, the airflow can not only dissipate heat to the radiator, but also directly dissipate heat to the lamp tube, thereby increasing the heat dissipation area and improving the heat dissipation efficiency.

[0007] Preferably, the air duct 1 and the air duct 2 both have an arc segment, the arc segment is located close to the fan, and the rear segment is a straight segment, which can increase the length of the heat dissipation channel within a limited space.

[0008] Furthermore, the heat dissipation fins are arranged in several groups, and have heat dissipation fins of various sizes. The front section of the heat dissipation fins is also arc-shaped, and channels for air flow are formed between the heat dissipation fins. The long and short heat dissipation fins design can reduce wind resistance, reduce the reaction force effect of wind, and improve airflow discharge efficiency.

[0009] According to an embodiment of the present invention, the air duct one and the air duct two are separated by a partition provided on the bracket.

[0010] According to one embodiment of the present invention, the radiator is provided with an air inlet channel for airflow to enter, and a side of the radiator where the heat pipe is installed is also provided with a plurality of strip-shaped protrusions, which have a heat dissipation effect when the airflow passes through, further improving the heat dissipation efficiency.

[0012] Optionally, the heat pipes can be arranged in multiple groups.

[0013] Optionally, the heat pipe is a U-shaped heat pipe or a straight heat pipe or other shapes.

[0014] According to an embodiment of the present invention, the radiator is a die-cast aluminum radiator, which is combined with a double air duct structure design to solve the problem of slow heat transfer of the die-cast aluminum radiator.

[0015] According to an embodiment of the present invention, the fan is mounted on a bracket.

[0016] A hair removal device comprises the above-mentioned dual-air duct heat dissipation module, a cooling fin and a lamp tube, wherein the lamp tube is located in the second air duct, and the cooling fin is in contact with the heat pipe.

[0017] The beneficial effect of the present invention is that, through the dual-channel setting, the airflow can not only dissipate heat to the radiator, but also directly dissipate heat to the lamp tube, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. Combined with the dual-duct structure design, it solves the problem of slow heat transfer of the die-cast aluminum radiator, and to a large extent avoids the problems of poor user experience and reduced service life of the hair removal device due to poor heat dissipation.
