Description
Technical field
The utility model belongs to the power semiconductor scope, particularly a kind of three phase rectifier half-bridge module of motor with radiating fin.
Background technology
Existing motor is not with radiating fin with the three phase rectifier half-bridge module, just by the package floor heat radiation, area of dissipation is very little, do not satisfy the requirement of power rectifier pipe far away, only take to install additional in addition radiating block and improve heat-sinking capability, thereby increase the installing space of three phase rectifier half-bridge module, increase simultaneously use cost.
The utility model content
The purpose of this utility model is to improve heat-sinking capability for taking to install in addition radiating block additional in the prior art, thereby increase the installing space of three phase rectifier half-bridge module, increase simultaneously the deficiency of use cost, a kind of three phase rectifier half-bridge module of motor with radiating fin is proposed, it is characterized in that, package casing at the three phase rectifier half-bridge module is the good metal shell of heat conduction, on its inner arc surface with connecing fin; Be mounting bracket at the package casing two ends, on the side of package casing three binding posts be set.
On the inner arc surface of described package casing and the exterior arc surface or inner arc surface, exterior arc surface and two sides are simultaneously with fin.
The upper surface of described package casing is the high-strength insulating plate, can bear-55 ℃ ~ 150 ℃ temperature range, is packaged with in the above three binding posts, and three binding posts are ac input end, and shell is output.
Described package casing is AL alloy arcuate structure.
The beneficial effects of the utility model are that package casing has arcuate structure, and its radius is fit to motor mounting space; It all is AL alloying metal structure and is with radiating fin, lightweight except three binding post places of encapsulation, is no more than 150g; Heat radiation is good, output current reaches 400A; Work and storage temperature range are wide, are-55 ℃ ~ 150 ℃.
Description of drawings
Fig. 1 is three phase rectifier half-bridge module surface structure schematic diagram.
Embodiment
The utility model proposes a kind of three phase rectifier half-bridge module of motor with radiating fin.Be explained below in conjunction with accompanying drawing.
Figure 1 shows that three phase rectifier half-bridge module surface structure schematic diagram, among the figure, on the inner arc surface of the package casing 2 of three phase rectifier half-bridge module with fin 4, perhaps on the inner arc surface of encapsulating shell and exterior arc surface or inner arc surface, exterior arc surface and two sides simultaneously with fin 4; Be mounting bracket 1 at package casing 2 two ends, the upper surface 5 of package casing 2 is the high-strength insulating plate, can bear-55 ℃ ~ 150 ℃ temperature range, is provided as in the above three binding posts 3 of ac input end.
The exterior shell of described envelope is AL alloy arcuate structure, as output.
Because package casing of the present utility model is arcuate structure, its radius is fit to motor mounting space; It all is AL alloying metal structure and is with radiating fin, the lightweight 150g of being no more than except three binding post places of encapsulation; Heat radiation is good, output current reaches 400A; Work and storage temperature range are wide ,-55 ℃ ~ 150 ℃.
Claims (4)
1. the three phase rectifier half-bridge module of the motor with radiating fin is characterized in that, on the inner arc surface of the package casing of three phase rectifier half-bridge module with fin; Be mounting bracket at the encapsulating shell two ends, three binding posts are set on the upper surface of package casing.
2. the described three phase rectifier half-bridge module of motor with radiating fin according to claim 1 is characterized in that, on the inner arc surface of described package casing and the exterior arc surface or inner arc surface, exterior arc surface and two sides are simultaneously with fin.
