Be detachably connected, convenient disassembly is easy to maintenance.
It is high by designing the low back plate 5 of foreboard 4 in the present embodiment so that be inside whole receiving cavity it is preceding it is high after low sky
Between, and circuit board is set at the top of receiving cavity, in the metal bending knee-piece 29 of receiving cavity bottom design one, and by the convex of curved tabs
The portion of rising corresponds to circuit board, the air admission hole 17 of foreboard 4, receiving cavity and interior metal curved tabs, and the heat emission hole 31 of back plate 5 is entirely constituted
One heat dissipation wind channel, and coordinate the miniature extraction fan of back plate 5 that the cold air of exterior space is worked into what is distributed by circuit board through air channel
Heat is taken out of outside receiving cavity, and whole Duct design rationally, the radiating effect of maximum is reached using minimum space.
With reference to shown in Fig. 4, to the force analysis on the inclined-plane of metal bending knee-piece 29, it is assumed that when the horizontal direction for blowing into air channel
Fly wind when act on wind-force size F1 on 45 ° of inclined-plane, wind-force F1 can be simultaneously by reaction force of the inclined-plane to F1, such as
Fruit does not consider other external force factors, then the reaction force direction that F1 is subject to should be F2 as shown in Figure 4 direction, that is, hangs down
It is straight upward, but wind-force F3 is additionally contemplates that, so, the real wind direction after inclined-plane reaction force should be F4
Direction of a curve.Just because of F4, this part of wind action power, allows the wind for blowing into air channel to form certain wind in circuit board surface
Pressure, this will greatly increase the heat that wind is taken away, and can effectively reduce circuit board temperature.The effect on the inclined-plane of metal bending knee-piece is not only
Only be it is described above it is simple play a part of a reaction force to gas, pass through the force analysis of whole housing：Tiltedly
Resistance is initially formed in face of blowing into the air-flow in air channel, can thus make it that the air velocity of air channel inner bottom part is slack-off, and in air channel
The air velocity of upper part is fast, and according to hydromechanical Bernoulli equation, the speed of fluid is faster, and pressure is just smaller to be understood, wind
Overall pressure inside road is that upper part is small, and lower part is big, so, the pressure inside air channel is overall upward, and this again will be certain
Pressure of the air channel inside wind to circuit board surface is added to degree, this is also beneficial to preferably radiating.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be protection domain of the present utility model.
