Detailed description of the invention
Fig. 1 is the structural schematic diagram of heat dissipation type box-type substation described in the utility model.
Specific embodiment
With reference to the accompanying drawing and preferred embodiment is described in further detail technical solution described in the utility model.
As shown in Figure 1, heat dissipation type box-type substation, comprising: the cabinet 1 of box-type substation, cabinet 1 include 11 He of internal box
Outer case 12,12 the cover of outer case are provided with cavity 13 in the outside of internal box 11 between internal box 11 and outer case 12,
The top of outer case 12 is provided with the opening 2 of several perforations, 13 bottom of cavity between internal box 11 and outer case 12 is set
Several drainage channels 3 are equipped with, drainage channel 3 is connected to bottom water tank 4.When the rainy day, rainwater can pass through 12 top of outer case
Opening 2 enters in the cavity 13 between internal box 11 and outer case 12, and enters to bottom water tank 4 by drainage channel 3, from
And collect rainwater.Sequentially connected water pump 5, heat exchanger 6 and screwed pipe 7 are fixedly installed in the internal box 11, specifically:
The water inlet pipe 51 of water pump 5 is connected with water tank 4, and the outlet pipe 52 of water pump 5 is connected with heat exchanger 6, heat exchanger 6 and screw thread
One end of pipe 7 is connected, and the other end of screwed pipe 7 is connected to water tank 4.In the present embodiment, it is arranged inside the internal box 11
There is humidity sensor 8, humidity sensor 8 is connected to the control system, and control system is connected with dehumidifying blower 9, and dehumidify blower 9
Exhaust outlet be connected in the cavity 13 between internal box 11 and outer case 12 by pipeline 10, when humidity sensor 8 senses
When the interior humidity of internal box 11 is higher than specified humidity standard, control system starting dehumidifying blower 9, thus in internal box 11
Portion carries out dehumidification treatments, and steam is disposed in the cavity 13 between internal box 11 and outer case 12, is passed through after moisture condensation
Drainage channel 3 enters in water tank 4.In the present embodiment, the water tank 4 is connected with external water source 23, the water in water tank 4
When insufficient, it can be fed by external water source 23.In the present embodiment, the outside of the internal box 11 is coated with one layer and prevents
Rotten water barrier 21.Under the protection of anti-corrosion water barrier 21, the rainwater in cavity 13 be cannot be introduced into internal box 11, thus anti-
The only electronic component dampness in internal box 11, improves waterproof performance.In the present embodiment, the anti-corrosion water barrier 21 is point
The ultra high molecular polyethylene layer that son amount is 3,000,000, high molecular polythene is the existing product that can directly purchase in the market, and
And have the advantages that favorable anti-corrosion effect, at low cost, using above-mentioned high molecular polythene as the material of anti-corrosion water barrier 21, Neng Gou great
The big service life for improving product.In the present embodiment, one layer of puigging 22, sound insulation are coated on the inner wall of the internal box 11
Several regularly arranged tapered conical holes are provided on layer 22.In such manner, it is possible to which the noise of effectively smaller box-type substation, avoids making
At noise pollution.
The working principle of the heat dissipation type box-type substation of above structure is as follows: when the rainy day, rainwater can pass through outer case 12
The opening 2 at top enters in the cavity 13 between internal box 11 and outer case 12, and enters to bottom water by drainage channel 3
Case 4, to collect rainwater.When ambient temperature is higher than 30 degrees Celsius, start water pump 5, the rainwater that water pump 5 will be collected in water tank 4
It pumps in heat exchanger 6, the refrigerant in heat exchanger 6 carries out cooling to rainwater to form water at low temperature, and water at low temperature passes through disk
The screwed pipe 7 inside internal box 11 is wound on to be back in water tank 4 and in the process to cooling down inside internal box 11.
In addition, being able to carry out water supply by external water source 23 when the rainwater water shortage collected in water tank 4.In internal box 11
In be additionally provided with humidity sensor 8, when humidity sensor 8 senses that the interior humidity of internal box 11 is higher than specified humidity standard
When, steam is disposed to interior case so that the inside to internal box 11 carries out dehumidification treatments by control system starting dehumidifying blower 9
In cavity 13 between body 11 and outer case 12, entered in water tank 4 after moisture condensation by drainage channel 3.
The advantages of heat dissipation type box-type substation of above structure, is: one, using rainwater as the main of water needed for heat exchange
Source, not only environmental protection but also reduce costs;Two, pass through the mating reaction of humidity sensor and the blower that dehumidifies, it can be ensured that internal box
In humidity be within the scope of specified value, prevent the electronic component in internal box from making moist, and directly logical after moisture condensation
Drainage channel is crossed to enter in sewer, it is very convenient;Three, by coating one layer of anti-corrosion water barrier on the outer wall of internal box, make
Obtaining rainwater cannot be introduced into internal box, to greatly promote waterproof effect.
