Specific embodiment

The utility model is specifically addressed now in conjunction with attached drawing, so that those skilled in the art can fully understand this reality With novel concrete principle and the course of work.

As shown in Figures 1 to 4: a kind of modularization box-type substation, including internal module, the internal module include high pressure Module 1, low-voltage module 2 and substation's module 3, which is characterized in that further include several groups radiating module 4, the radiating module 4 is Bar shaped stereo hollow structure, between the high-pressure modular 1, low-voltage module 2 and substation's module 3, the radiating module 4 with Internal module opposite face is equipped with several heat dissipation holes 41, and the heat dissipation hole 41 is in honeycomb arrangement, on the radiating module 4 Surface is bonded substation casing and is in communication with the outside.

The utility model is equipped with radiating module 4 between the module of substation, will be in the work of its two sides by radiating module 4 Internal module heat take away.Compared to the radiating mode of traditional substation (several radiator windows are arranged in substation casing), originally The radiating module 4 of utility model is more nearly from the internal module in work, is radiated more direct, effect is more significant.

Particularly the radiating module 4 is bar shaped stereochemical structure, and the length direction of length direction and internal module is big It causes unanimously, to be connected at the top of short transverse and substation, the radiating module 4 is with internal module opposite face equipped with several heat dissipations Hole 41.Inside heat dissipation hole 41, radiating module 4, a heat transmission channel is equivalent at the top of radiating module 4.

In normal work, the heat of internal module enters radiating module 4 by heat dissipation hole 41, pushes up from radiating module 4 Portion sheds.Since 4 both sides of radiating module are the internal modules in work, radiating mode is equivalent to the naturally right of heat Stream sets honeycomb arrangement for heat dissipation hole 41 to keep convection effects more significant.In a preferred embodiment, Each heat dissipation hole can be also provided with into honeycomb (regular hexagon hole).

The preferred radiating module 4 is ceramic material, and the opposite face of radiating module 4 and internal module is in being recessed inwardly one Determine radian.Due to the poor thermal conductivity of ceramics, temperature rise is slow, according to the hydrodynamics of gas it is found that in radiating module 4 and internal module Heat dissipation hole 41 on opposite face, which is equivalent to, has a static attraction to the heat that internal module distributes, and can so promote heat Free convection, more efficiently accelerated heat scatter and disappear.So set, radiate compared to traditional radiator window, radiating efficiency can be with Improve 53%~85%.

In order to make better heat-radiation effect, exhausting device 5, the exhausting device are additionally provided on radiating module 4 Air draft fan leaf 51, control centre 52 and temperature sensor 53 including 4 top of radiating module is arranged in.So set, can be Substation starts exhausting device 5 when the temperature is excessively high, and accelerated heat is scattered and disappeared, so equivalent to increase a pressure heat Convection device.Specifically by temperature sensor 53 measure substation's internal temperature, when temperature be more than one periodically (such as: 50 DEG C), air draft fan leaf 51 is started by control centre 52, accelerated heat convection current improves radiating efficiency.

There are toy or sundries to enter at the top of radiating module 4 in order to prevent, sets metal isolation net 42 in upper surface.

Sleet enters from 4 top of radiating module in order to prevent, and temperature caused by sun solarization is further prevented to increase, Substation's top certain distance is additionally provided with ceramic isolation board 6, and the surface cover of the ceramics isolation board 6 crosses substation upper surface.It needs It should be noted that the ceramics isolation board 6 should be appropriate with substation upper surface distance, it is closely not easy very much shedding for temperature, too far installation It is inconvenient and keep substation's overall volume aobvious big, generally it is advisable in 20cm~40cm.

The present embodiment reaches heat free convection by above-mentioned radiating module shape setting, then passes through exhausting device It realizes heat forced convertion, by dual heat loss, improves heat loss efficiency.It radiates compared to traditional radiator window, heat dissipation Efficiency can be improved 80%~110%.

Although the utility model is through the foregoing embodiment and attached drawing has clear explanation, however practical new without departing substantially from this In the case where the spirit and essence of type, person of ordinary skill in the field can be made according to the utility model corresponding variation and Amendment, and these variations and modifications all should belong to the protection scope of the utility model.
