Abstract
The utility model relates to a radiator for large-power device, and belongs to the technical field of mechanics. The radiator comprises a plug sheet group, an upper plug sheet substrate, and a lower plug sheet substrate. The plug sheet group is a group of plug sheets of identical structure and respectively inserted into corresponding slots in the upper and lower plug sheet substrates. The plug sheet is provided with threaded holes reserved on two sides, chamfered edge, and top positioning pin hole. Under the same volume, this radiator has larger heat dissipation area than solid plug sheet radiator. Furthermore, the radiator has highly smooth upper and lower surfaces, good contact with power device, and greatly improved heat dissipation efficiency, and satisfies increasingly high requirement of power device for heat dissipation. The threaded holes are used for connecting with copper busbar or lead, and the chamfered edge is used for avoiding point discharge. The entire radiator has advantages of concise structure and good appearance.
Description
Technical field
The utility model relates to the power application electronic applications, especially the high power device heat dissipation equipment.Belong to field of mechanical technique.
Background technology
Both at home and abroad the radiator kind is a lot, and it is also quite a lot that inserted sheet press-fits the radiator of type, but its inserted sheet all is solid, and area of dissipation is little, has influenced the heat dispersion of radiator.Along with the development of novel electric power electric device, also more and more higher to the requirement of radiator heat-dissipation, need develop radiator novel, that area of dissipation is bigger.
Summary of the invention
The purpose of this utility model is the shortcoming at above prior art existence, and the radiator of the higher new structure of a kind of radiating efficiency is provided.
In order to reach above purpose, the utility model is to take following technical scheme to realize:
A kind of radiator that is used for power device comprises the inserted sheet group, it is characterized in that it also comprises inserted sheet substrate, following inserted sheet substrate; The inserted sheet group is one group of inserted sheet that structure is identical, inserts respectively in the corresponding slot of upper and lower inserted sheet substrate.
Aforesaid a kind of radiator that is used for power device is characterized in that wherein said inserted sheet both sides leave screwed hole, edge chamfer, and dowel hole is arranged at the top.
A kind of radiator that is used for power device of the utility model is formed by last inserted sheet substrate, middle inserted sheet group, following inserted sheet substrate three part crimping.Middle inserted sheet group is one group of inserted sheet that structure is identical, inserts respectively in the corresponding slot of upper and lower inserted sheet substrate, and middle inserted sheet central inner and both sides are the ventilation hole of radiator.There are the very high depth of parallelism and fineness in the upper and lower surface of this radiator, and screwed hole is left in both sides, edge chamfer, and dowel hole is arranged at the top.Power device is installed on radiator two ends up and down, fixes with alignment pin and radiator.In working order down, the moving air of forced convertion through the ventilation hole of radiator, is taken away the heat on the radiator.
This radiator is under the equal volume condition, have than the more area of dissipation of solid fin inserting type heat radiator, and the upper and lower surperficial best bright finish of radiator well contacts with power device, makes radiating efficiency improve greatly, satisfies the more and more higher heat radiation requirement of various power electronic power devices.The screwed hole of both sides is used to connect copper bar or lead, and edge chamfer is avoided point discharge.Entire radiator is succinct, and is attractive in appearance.

The instance graph that Fig. 3 is used in combination with power semiconductor for radiator of the present invention.
Among the figure: 1, inserted sheet substrate, 2, inserted sheet, 3, power semiconductor, 4, conducting copper, 5, set bolt
Embodiment
A kind of radiator that is used for power device of the utility model as Figure 1-3, among its Fig. 1, one inserted sheet group (2) two ends are inserted respectively in the slot of upper and lower inserted sheet substrate (1), what the slot of the pin of inserted sheet (2) and upper and lower inserted sheet substrate (1) adopted is interference fit, exert pressure, make inserted sheet (2) and upper and lower inserted sheet substrate (1) form an integral body.This radiator section up and down partly has the dowel hole (see figure 2), is used for fixing power semiconductor; There is the location fastener hole side, is used to install conducting copper; Edge designs has chamfering, prevents point discharge.
Each end face of power device among Fig. 3 (3) is connected with the upper and lower plane of radiator, and there are higher smoothness and flatness in the upper and lower plane of radiator.Conducting copper (4) is fixed on the radiator side by set bolt (5), makes radiator, power device (3), conducting copper (4), set bolt (5) form an assembly, satisfies the needs of the normal steady operation of power device.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
Claims (2)
1, a kind of radiator that is used for power device comprises the inserted sheet group, it is characterized in that it also comprises inserted sheet substrate, following inserted sheet substrate; The inserted sheet group is one group of inserted sheet that structure is identical, inserts respectively in the corresponding slot of upper and lower inserted sheet substrate.
2, a kind of radiator that is used for power device according to claim 1 is characterized in that wherein said inserted sheet both sides leave screwed hole, edge chamfer, and dowel hole is arranged at the top.
