[0024] The utility model will be further described in combination with specific embodiments as follows:

[0025] A high-pressure cooling fan includes a fan housing 1 with an exhaust port 11 on it. The fan body 2 is disposed in the fan housing 1. The fan body 2 includes a drive motor 21 and a pump head 22 connected to one side of the drive motor 21. The pump head 22 has an air intake port 221 and an air outlet 222. The air outlet 222 passes through the fan housing 1 and connects to the outside. The air intake port 221 is located inside the fan housing 1.

[0026] like Figure 1 As shown, the fan casing 1 in this application is a closed shell formed by metal plates. A vertically placed partition plate 4 is provided inside the closed shell, separating the fan mounting cavity 42 and the electrical control mounting cavity 41. The fan body 2 is disposed in the fan mounting cavity 42, and includes a drive motor 21. The drive motor 21 includes a housing, and a rotor and stator are disposed inside the housing. One end of the drive motor 21 is provided with a pump head 22, which has an air intake 221 and an air outlet 222. The air outlet 222 passes through the side wall of the fan casing 1 and communicates with the outside. The air intake 221 is directly disposed on the pump head 22 and located inside the fan casing 1. The electrical control mounting cavity 41 is used to install electrical control components, which are used to control the operation of the drive fan body 2.

[0027] The heat dissipation duct 3 is connected to the exhaust port 11. The heat dissipation duct 3 has an air outlet 31 facing the drive motor 21. It is used to draw air through the air inlet 221 so that the external airflow enters the heat dissipation duct 3 from the exhaust port 11, and then is sent out from the air outlet 31 through the drive motor 21 into the air inlet 221.

[0028] like Figures 1-3 As shown, the air intake 221 is located on one side of the fan casing 1. The air intake 221 is square, and the heat dissipation duct 3 is provided inside the air intake 221. Specifically, the exhaust port 11 has an inwardly facing square first annular baffle 112 along its edge. The first annular baffle 112 has an installation space for installing the grid frame 111. The grid frame 111 in this application consists of an outer frame body adapted to the shape of the air intake 221 and a grid mesh fixed in the outer frame body. The outer frame body can be connected to the first annular baffle 112 by fasteners. The grid frame 111 has a plurality of air passages 1111 formed therein. The grid frame 111 effectively prevents foreign objects from entering the fan casing 1 while ensuring effective air intake.

[0029] Combination Figure 3 , 4As shown, the first annular baffle wall 112 is further provided with a wind guide 113, the center of the wind guide 113 is provided with a heat dissipation air outlet pipe 114, the heat dissipation air outlet pipe 114 is provided with the air duct outlet 31, and the first annular baffle wall 112, the wind guide 113 and the heat dissipation air outlet pipe 114 are connected to form the heat dissipation air duct 3. The wind guide 113 is square, which is connected to the end of the first annular baffle wall 112, and the center of the wind guide 113 is provided with a circular heat dissipation air outlet pipe 114, which faces the driving motor 21.

[0030] When the fan body 2 in the fan cover 1 works, the air inlet 221 is opened to draw air, the wind force enters the heat dissipation air duct 3 from the air outlet 11, and then enters the fan cover 1 from the air duct outlet 31 of the heat dissipation air duct 3, and blows to the fan body 2 in the fan cover 1, especially the driving motor 21 part in the fan body 2 which is easy to heat. From this, the application sets the air inlet 221 in the fan cover 1 and sets the corresponding heat dissipation air duct 3 to use the suction force of the high-pressure fan to suck the wind force, and uses the wind force to dissipate heat for the fan body 2, so as to prevent the fan body 2 from overheating and affecting its normal use or service life.

[0031] Further, the driving motor 21 is provided with a heat dissipation end 211, the heat dissipation end 211 is located in the air duct outlet 31, and the outer edge of the heat dissipation end 211 and the air duct outlet 31 have a wind guide gap 212. As shown, Figure 3 As shown, the driving motor 21 in the application is square as a whole, one end thereof facing the heat dissipation air duct 3 is the heat dissipation end 211, the other end thereof opposite to the heat dissipation end 211 on the fan body 2 is provided with the air inlet 221, and the cross-sectional size of the heat dissipation end 211 is slightly smaller than the size of the air duct outlet 31, so that when the heat dissipation end 211 is located in the air duct outlet 31, the outer edge of the heat dissipation end 211 is shaped as the wind guide gap 212.

[0032] Since the heat dissipation end 211 is located in the air duct outlet 31, the wind sucked by the air inlet 221 will move along the wind guide gap 212, so that the wind sucked by the air inlet 221 will adhere to the outer wall of the driving motor 21, so that the driving motor 21 is fully adhered to the wind, thereby increasing the heat dissipation effect.
