Description
Technical field
The utility model patent relates to a kind of cooling mechanism, relates in particular to a kind of cooling mechanism of buried substation.
Background technology
Present buried substation of the prior art is new things, can cable be connected all be embedded in undergroundly with transformer, reduce face of land floor space, but this has also derived another problem to be solved---heat radiation.The more conventional radiator structure of heat sinking structure that we designed now has very big improvement.
Conventional radiator structure is that shutter is offered in the high and low voltage chamber bottom; One side is with axial flow blower air draft outward; Though also play thermolysis; But drawback is an inlet and outlet is parallel position, and cold air has most of process axial flow blower directly to discharge when opposite side advances, and does not get into melt pit and carries out thermal cycle.
Chinese patent CN200520125409.2; Disclose a kind of buried substation, comprise housing, hyperbaric chamber, low-pressure chamber, transformer room, it is characterized in that: described transformer room is embedded in underground; The two side, transformer room is provided with ventilation shutter; Be provided with scavenge duct between both sides, corresponding with it transformer room and the housing, be used for ventilation, the heat radiation of transformer room, the housing sidewall top is provided with air inlet, the gas outlet of scavenge duct; Air inlet, gas outlet are positioned on the ground, and on air inlet and gas outlet, are equipped with blower fan.In order to realize automatic control, the blower fan that install at described air inlet, place, gas outlet all connects temperature humidity switch, and is controlled by temperature humidity switch.This structure relative complex, and radiating effect is not good.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and can carry out the cooling mechanism of the buried substation that the office of cycle heat radiation puts.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of cooling mechanism of buried substation comprises melt pit, is provided with the transformer pedestal in the described melt pit; Be provided with transformer in the described transformer pedestal, described transformer pedestal is provided with high and low voltage chamber, and the lower end sidewall of described high and low voltage chamber is provided with air inlet; One side of described air inlet is provided with thermal insulation layer; Described thermal insulation layer is positioned at high and low voltage chamber, and described air inlet and thermal insulation layer form cold air channel, and described transformer and transformer pedestal form heat dissipation channel; The upper end sidewall of described transformer pedestal is provided with air outlet; Form air exhaust passage between described thermal insulation layer and high and low voltage chamber, described air exhaust passage is connected with air outlet, and described cold air channel, heat dissipation channel and air exhaust passage are connected.
Novel radiator structure isolates the high and low voltage chamber back come out separately, and is separated by with thermal insulation board, offers shutter at the top; With axial flow blower air discharging and radiating outward, like this, because hot-air density is little; Up assemble, advanced axial flow blower again and take out, can produce the air channel soon.Because the discharge of hot-air causes the melt pit internal gas pressure on the low side, high and low voltage chamber's opposite side bottom shutter air inlet just gets into cold air smoothly; Cold air density sinks greatly, continues hot-air is up lifted, and gets into heat dissipating layer; Carry out thermal cycle like this, can play efficiently radiates heat.
As preferably, described air inlet lateral wall be provided with down shutter, described air outlet is provided with axial flow blower, the lateral wall of described air outlet is provided with shutter.
As preferably, described air exhaust passage is a vertical channel.
The utility model provides a kind of cooling mechanism of buried substation, and is simple in structure, and superior performance reduces environmental pollution.
