Description
Technical field
The utility model relates to the technical field of electric motor car, particularly relates to the radiator structure of electric motor car power device.
Background technology
In electric motor car, its internal power device caloric value when electric motor car load running is comparatively large, understood cause thermal damage, and caused correlation function to lose efficacy if distribute not in time.So the quality of electric motor car internal structure heat dispersion determines the quality of electric motor car to a certain extent.
Because electric motor car is when car load assembles, internal power device is arranged in a confined space, the radiator structure of most employing casing integration carrys out nature cooling heat dissipation, existing casing integral heat dissipation structure only simply increases rectangular fin to increase area of dissipation at power device radiating surface or surrounding, its radiating efficiency is not high, often need to increase supplemental heat rejected facility with satisfied heat radiation, such as install air-cooled or water cooling equipment auxiliary heat dissipation additional, although this mode improves heat radiation, but be the increase in structure complexity, improve cost.
Utility model content
The purpose of this utility model is to provide power device radiating structure, and the own radiating effect of radiator structure being intended to the power device solving electric motor car in prior art is poor, and needing increases the problem that cost arranges supplemental heat rejected facility.
The utility model realizes like this, power device radiating structure, heat radiation is provided for the power device for electric motor car, comprise the housing of hollow, described enclosure interior is fixed with pcb board, and multiple described power device is placed on described pcb board, and described case inside face is close in each described power device side, described hull outside face is provided with multiple for strengthening the fin dispelled the heat, and described fin comprises highly different and the high fin of alternate setting and low fin.
Further, in the two opposite side walls of described enclosure interior, correspondence is provided with and snaps in fixing groove for described pcb board.
Further, described case inside is provided with projection, and described power device is attached on described projection.
Further, between described high fin height scope is two times to three times of described low fin height.
Further, described fin bearing of trend is parallel to described power device and is sticked in the orientation of described case inside.
Further, the shape in described fin cross section is trapezoidal.
Further, the shape indention in described fin cross section.
Further, the shape undulate in described fin cross section.
Compared with prior art, the power device radiating structure in the utility model, its fin has two kinds of height, i.e. high fin and low fin, two kinds of alternate settings of fin, change original heat-dissipating space, improve radiating efficiency, do not need additionally to arrange auxiliary equipment again.

Fig. 2 is the schematic cross-section of trapeziform rib in the utility model embodiment;
Fig. 3 is that in the utility model embodiment, edge is the schematic cross-section of zigzag fin;
Fig. 4 is that in the utility model embodiment, edge is the schematic cross-section of waveform fin.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Be described in detail below in conjunction with the realization of concrete accompanying drawing to the present embodiment.
As shown in Figure 1, power device radiating structure, comprises the housing 1 of hollow, and housing 1 inside is fixed with pcb board 2, and multiple power device 3 is placed on pcb board 2, and the medial surface of housing 1 is close in side.Housing 1 lateral surface is provided with multiple fin for strengthening heat radiation, and fin comprises high fin 4 and low fin 5, and high fin 4 is highly different with low fin 5, and along the alternate setting of housing 1 lateral surface.
During heat radiation, heat is passed to fin by housing 1 by power device 3, and fin comprises high fin 4 and the low fin 5 of alternate setting, this setup changes heat-dissipating space structure of the prior art, between adjacent two high fins 4, define larger space, and low fin 5 itself is also placed in larger space dispels the heat.Detect through experiment, this heat dissipation design will exceed radiating efficiency 15 ~ 30% than contour design radiating efficiency, and radiating efficiency is higher, does not need can reach requirement by supplemental heat rejected facility.And height fin materials are less than contour fin by 5 ~ 15%, decrease materials cost.Power device radiating structure has perfect heat-dissipating, low cost and other advantages.
As shown in Figure 1, in the two opposite side walls of housing 1 inside, be provided with groove 7 separately, two groove 7 positions are relative, can snap in fixing for pcb board 2.The mode of this clamping, compared with other fixture fixed forms, can reserve larger heat-dissipating space, helps heat radiation, and assembling is comparatively easy.
Be provided with projection 6 in the inner side of housing 1, namely power device 3 is attached on projection 6.In practical set, because the part shape of power device 3 own is special, and plug and be placed on pcb board 2, be difficult to the inner side be directly sticked to housing 1, therefore projection 6 is set, make it more easily realize being sticked.
Outside housing 1, fin bearing of trend is parallel to power device 3 along the setting direction inside housing 1, the orientation be namely sticked on projection 6, and each power device 3 can be dispelled the heat by multiple fin simultaneously, improves the efficiency of heat radiation.In practice, can only at projection 6, namely housing 1 side-wall outer side of power device 3 of being sticked arranges fin, also can at whole housing 1 arranged outside fin, can require to design according to concrete heat radiation, space structure, cost control etc., in the outside of whole housing 1 in the present embodiment, be equipped with fin.
Through test of many times, when the altitude range of high fin 4 is twices to three times of low fin 5, radiating effect promotes comparatively large, and in the present embodiment, the height of high fin 4 is the twice of low fin 5.
The material of housing 1 and fin adopts the metal material that thermal conductivity is high, such as aluminium, copper, silver etc.
Fin shape can be set to multiple, can be following shape:
1) shape in cross section is trapezoidal as shown in Figure 2, and wherein trapezoidal top width is 1.5mm, and bottom width is 2.5mm, and the simple cost of trapezoidal processing is low;
2) cross section is trapezoidal as shown in Figure 3, edge shape indention, and wherein sawtooth difference in height is 0.2mm, and tooth pitch is 0.3mm, and this shape processing cost higher than common trapezoidal, but improves surface area, and radiating effect is better;
3) cross section is trapezoidal as shown in Figure 3, edge shape undulate, and wherein wave height difference is 0.2mm, wave is apart from being 0.3mm, and this shape is similar to zigzag, can provide close radiating effect by less wave quantity, can according to the production technology cost of reality, selected shape.
Power device radiating structure in the present embodiment, the different fin in highland that arranges straggly is utilized to dispel the heat, improve radiating efficiency, save material cost, and not needing extra auxiliary radiating device, its fin has various shape available, can according to the balance of actual cost and heat radiation, select different structures, there is applicability widely.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
