The hermatic door bottom of the housing offers air inlet, and each region by heat-dissipation spacer segmentation is corresponding Housing two side offers air outlet.

Lower floor's heat storing plate is copper base, and the heat accumulation piece set thereon is copper cooling fin, and the middle level heat-conducting plate is Heat conductive silica gel pad, the upper strata heat sink are aluminium base, and fin thereon is aluminium heat sink.

Thickness is more than rear side thickness on front side of the upper strata heat sink, so that upper strata heat sink quick heat radiating.

Beneficial effect：

1. the utility model Casing top using lower floor's heat storing plate, middle level heat-conducting plate and upper strata heat sink three ply board it is compound and Into lower floor's heat storing plate quickly absorbs enclosure interior heat and heat is passed into upper strata heat sink through middle level heat-conducting plate, through upper strata Fin on heat sink is lost to the external world, while the adjacent two fin top on the heat sink of upper strata is connected with heat-radiating substrate, On the one hand the area of dissipation of heat sink is increased, on the other hand two fin surround ventilation air duct with heat-radiating substrate, due in air channel Portion's temperature is more than ambient temperature, accelerates the convection current of air channel inner air, improves radiating efficiency；

2. setting 2-3 horizontal heat-dissipation spacers on enclosure interior vertical direction, on the one hand horizontal heat-dissipation spacer divides housing For 3-4 region, component is arranged on different regions according to the power of component, to factors such as the sensitivitys of temperature, Another aspect heat-dissipation spacer is embedded some fin to be hollow, inside it and hollow space is divided into multiple heat dissipation channels, both increases Big area of dissipation increases cross-ventilation speed again, and the heat-dissipation spacer for being vertically arranged enclosure interior forms gradient and radiated, and carries The radiating efficiency of high housing；

3. housing front closing door bottom offers air inlet, the side wall that each region of heat-dissipation spacer segmentation is set is set There is air outlet, each region forms heat loss through convection junior unit, improves the radiating efficiency of whole power distribution cabinet；

4. because in power distribution cabinet, component is arranged on enclosure interior rear wall so that heat is higher than outer on the inside of enclosure interior Side, it is uneven to prevent from radiating, radiating efficiency is reduced, upper strata heat sink is used front side thickness to be more than rear side thickness by the utility model Degree, enclosure interior high heat portion of heat transfer is set with part low in calories, to improve radiating efficiency soon.
