For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The present utility model will be described in detail below with reference to the drawings and various embodiments.
Fig. 1 is a three-dimensional schematic view of a first embodiment of the present utility model, and fig. 2 is a plan sectional view of the first embodiment of the present utility model. As shown in fig. 1 and 2, the high-speed wind tunnel of the present utility model comprises: the air outlet barrel 100 and the handle 200, the handle 200 and the inside of the air outlet barrel 100 are hollow structures, one end of the air outlet barrel 100 is an air outlet, the other end is closed, and the bottom of the handle 200 is an air inlet end of the air channel 102; the high-speed air duct is internally provided with an air duct 102 for accommodating high-speed air flow, a high-speed fan 201, a main control board and a power device 104 for driving the high-speed fan 201; the power device 104 is on the main control board and is on the path of the high-speed air flow in the air duct 102, so that the heat generated by the operation of the power device 104 is taken away by the high-speed air flow in the air duct 102.
When the high-speed air duct runs, high-speed air flow driven by the high-speed fan 201 flows from the lower part of the handle 200 to the upper part, turns, and flows to the air outlet of the air duct. The tunnel 102 in this embodiment is thus shaped like a transposed "L". In order to reduce the projected area of the power device 104 in the airflow direction in the air duct 102, and reduce the complexity of the internal structure of the air duct 102, so as to be more adaptive to aerodynamics, and reduce turbulence and noise caused by the disturbance of the airflow in the air duct 102, the power device 104 may preferably be in a surface-mounted package form.

The power device 104 is welded on the annular main control board 103 and is positioned at the upstream of the air duct 102 in the air outlet duct 100; the heating wire 101 is fixed downstream of the air duct 102 of the air outlet duct 100, near the outlet of the air duct 102. A key 202 is arranged on the side wall of the handle 200 and used for controlling the power on-off of the heating wire 101 and the high-speed fan 201. The dust screen 203 is located at the bottom of the handle 200 for filtering the air entering the air duct 102 to prevent foreign matters from entering the damage high speed fan 201.
Taking fig. 3 as an example, a surface mount packaged power device 104 (D-PAK) is shown, where the drain pins are cut off, and the drain pins are directly welded on the main control board by using a heat dissipation plate on the back as the drain, so as to output a large current on one hand and dissipate heat through the main control board on the other hand. When the surface-mounted packaged power device 104 is used, the bonding pads of the main control board are three, and the drain electrode bonding pad is larger.
