1. temperature rise, the loss of electric energy is large;
2. temperature rise is higher, the reduced lifetime that bus uses;
3. temperature rise, reduces coefficient of safety, easily causes adjacent material fire incident and shell high temperature to scald personnel;
4. temperature rise, has impact to the ambient temperature of surrounding;
5. enclosed busbar internal temperature rise is higher, and voltage just falls larger.
Summary of the invention
Technical purpose of the present invention is the design by two-phase closed type hot siphon radiating tube, the heat of high-temperature gas in cooling air channel is passed to the cold air in heat extraction air channel, thus the temperature in reduction cooling air channel, complete the heat radiation operation to enclosed busbar heat radiation, extend the useful life of enclosed busbar; A kind of intelligent distributed isolated-phase enclosed bus heat radiation cooling device is provided.
For solving above-mentioned technical problem, structure of the present invention comprises casing and heat-exchange device, described heat-exchange device is two-phase closed type hot siphon radiating tube, the both sides of described two-phase closed type hot siphon radiating tube are respectively provided with a mounting bracket, described two-phase closed type hot siphon radiating tube is fixedly connected in casing by mounting bracket, the inner space of described casing is separated into upper and lower two parts by two-phase closed type hot siphon radiating tube, described two parts are up and down heat extraction air channel and cooling air channel successively, also cooling blower is provided with in described heat extraction air channel, two-phase closed type hot siphon radiating tube in described casing is skewed.
Further: described two-phase closed type hot siphon radiating tube is by evaporation section, adiabatic section and condensation segment three part composition, described two-phase closed type hot siphon radiating tube is made up of metal shell, tube core and working medium, described tube core is arranged in metal shell, and described working medium filling is in tube core.
Further again: described two-phase closed type hot siphon radiating tube adopts aluminium alloy porous micro-channel tubes to add the version of louvered fin.
