Embodiment 1
[0027] In the embodiment of the present invention, a computer mainframe cooling device based on the principle of wind speed and pressure includes a mainframe casing 1, an air outlet 2 arranged on the side end of the mainframe casing 1 for hot gas discharge, and an air outlet 2 arranged on the mainframe casing 1 and connected to the air outlet. 2 The blast chamber 8 at the opposite position for the entry of new gas; the left and right ends of the blast chamber 8 are respectively provided with a fan outlet 9 and a fan inlet 10, and a useful The movable cavity 6 placed on the light movable plate 7, the movable cavity 6 is communicated with the inner side of the host casing 1 through the air inlet 5 of the main engine, the movable cavity 6 is communicated with the blast chamber 8 through the air outlet 9 of the fan, and the blower 8 cools the outside temperature The lower air is transported into the host shell 1 through the movable chamber 6, and the gas with a higher temperature i...
Embodiment 2
[0036] The present invention also provides another embodiment to improve the present application. Specifically, the difference between the second embodiment and the first embodiment is that the height of the inner cavity of the movable cavity 6 is greater than the height of the lightweight movable plate 7, and Sliding up and down on the lightweight movable plate 7, the lightweight movable plate 7 is provided with a plurality of through grooves 18, the end of the through grooves 18 away from the blast chamber 8 is arranged horizontally, and the end of the through groove 8 that fits the blast chamber 8 is inclined Shaped and parallel to the fan outlet 9, the fan outlet 9 is also inclined, the through groove 18 and the host air inlet 5 are staggered up and down, and the blast chamber 8 blows the gas obliquely upwards to the light through the fan outlet 9. The movable plate 7, when the gas passes through the horizontal end on the through groove 18, makes the horizontal plate 17 hav...
