The utility model discloses a kind of power device and radiator crimping structure, comprise radiator and the many groups of power device groups be arranged on radiator, 2 power devices that often group power device group is arranged by parallel interval are formed, the top of described power device is provided with crimping bar, the center of described crimping bar is fixedly connected with radiator by securing member, the lower surface of crimping bar corresponds to the position of power device and is provided with balance briquetting for force balance, described balance briquetting is positioned at the center of power device upper surface, and is close to the upper surface of power device.Described a kind of power device and radiator crimping structure are by setting up balance briquetting in the center of power device, when crimping bar is fixed on radiator by securing member, the pressure that crimping bar is subject to can be delivered on power device uniformly, and then make pressure that power device can be effective, smooth on a heat sink, thus power device is dispelled the heat evenly, extend its useful life.
Description
Technical field
The utility model relates to power electronic device technical field, particularly relates to a kind of power device and radiator crimping structure.
Background technology
Power device is the core component of various novel high-power power electronic equipment, generally all needs to utilize crimping bar it to be pressed in tightly on smooth radiator, so that the assurance device that dispels the heat better normally works.At present, the traditional crimping mode of power device be all with one piece of crimping bar across on two power devices, then at the central aperture of crimping bar, pin tightly on a heat sink through crimping bar with screw; When screw is locked on a heat sink tightly, crimping bar is under pressure and power device pressure on a heat sink.
But, there is certain defect in the crimping structure of above-mentioned power device, even the rigidity crimping bar that intensity is good, often because the stressed stressed little power device discontinuity that causes in two ends greatly in central screw place, and then cause power device effectively, not entirely to be crushed on radiator, thus cause the heat radiation of power device uneven, have a strong impact on performance and the life-span of power device, even can affect and damage power electronic equipment, causing serious economic loss.
Utility model content
The purpose of this utility model is for the problems referred to above, a kind of power device and radiator crimping structure are provided, to solve existing power device and radiator crimping structure discontinuity, make pressure that power device can not be effective, smooth on a heat sink, cause power device to dispel the heat uneven, affect the problem in power device performance and life-span.
The purpose of this utility model is achieved through the following technical solutions:
A kind of power device and radiator crimping structure, comprise radiator and the many groups of power device groups be arranged on radiator, 2 power devices that often group power device group is arranged by parallel interval are formed, the top of described power device is provided with crimping bar, the center of described crimping bar is fixedly connected with radiator by securing member, the lower surface of crimping bar corresponds to the position of power device and is provided with balance briquetting for force balance, described balance briquetting is positioned at the center of power device upper surface, and is close to the upper surface of power device.
As preferred version of the present utility model, described balance briquetting with crimp bar and be structure as a whole.
As preferred version of the present utility model, described balance briquetting is Split type structure with crimping bar, and balance briquetting is close to the upper surface of power device by crimping bar.
As preferred version of the present utility model, described securing member is screw, described radiator has the screwed hole matched with screw.
The beneficial effects of the utility model are, described a kind of power device and radiator crimping structure are by setting up balance briquetting in the center of power device, when crimping bar is fixed on radiator by securing member, the pressure that crimping bar is subject to can be delivered on power device uniformly, and then make pressure that power device can be effective, smooth on a heat sink, thus power device is dispelled the heat evenly, extend its useful life.
