Embodiment Construction

[0045] The structure and effect of the present invention will be described in detail by citing the following embodiments in conjunction with the accompanying drawings.

[0046] The invention relates to a base of a heat dissipation structure, which is provided with a groove on the base, and the groove is located outside the outer diameter of the shaft tube. The design of the groove can effectively block the influence of the internal stress of the cooling contraction on the shaft tube, avoiding Shaft tube deflection improves product quality and life.

[0047] Several preferred implementation forms of the present invention are listed below for illustration.

[0048] Such as figure 2 , image 3 As shown, it is the first embodiment of the present invention, which includes:

[0049] A base 10, except for the air outlet side 14, is surrounded by side walls 11 to form an accommodating space 12. A fan wheel and a stator group (not shown) are arranged inside the accommodating space ...

Abstract

The invention relates to a base of a radiating structure, comprising a base provided with an axle casing, the hole at the center of the axle casing is for arranging a bearing to support the rotation of the rotary axis of a sector, the base is equipped with a groove located in a scope outside the external diameter of the axle casing. According to the invention, the unevenness problem of the shrinkage inner stress caused by cooling time and temperature difference is effectively solved by using the groove, the declination of the axis casing is prevented to support the stable operation of the rotary axis of the sector, derivative swing and noise are avoided, the vibration and noise test of a product conforms to standard scope, the unqualified rate is lowered, and the service lift the product is extended.

Description

Technical field [0001] The present invention involves a base of the heat dissipation structure, which can effectively avoid the internal stress of the cooling contraction of the base and cause the center line of the axis tube to ensure the practicality of the product quality and life. Background technique [0002] like figure 1 The heat dissipation structure shown in Xi contains: [0003] 10 seats 10, the surrounding side is surrounded by side walls 11 to form a one -to -capacity space 12, and the internal configuration of the capacity of the capacity of the capacity is configured with a certain sub -group (in the figure that it is not shown in the figure, because the driving relationship between the fan wheel and the stator group is Xi as Xi as Xi is Xi as Xi as Xi is Xi.Knowing technology, there is no direct connection with this case, will not repeat it in the article), there is a shaft tube 13 in the inside space 12, the axis tube 13 can be assembled or integrated on the base ...
