Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the portion the A enlarged diagram of the utility model Fig. 1.
Specific embodiment
In conjunction with Fig. 1, Fig. 2, a kind of direct current cabinet cabinet body with high temperature warning function, including cabinet body 1,1 side of cabinet body
Be hinged with cabinet door 2, the other side is fixed with inflator 3, lower end is fixed with tank for coolant 4, be provided with air bag 5 in the tank for coolant 4,
Piston 6 is fitted in the inflator 3；The cabinet plate 7 that the cabinet body 1 leads in forms, and the cabinet plate 7 is interconnected, the cabinet plate 7
Inner space is separated into cooling chamber 9, heat-absorbing chamber 10 by cavity plate 8, and the heat-absorbing chamber 10 is located inside and equipped with coolant；The gas
3 upper ends are connected to cylinder with 10 upper end of heat-absorbing chamber, lower end is connected to air bag 5, and 9 upper end of cooling chamber is connected to tank for coolant 4, lower end
It is connected to by check valve 11 with 4 upper end of tank for coolant；1 inner tip of cabinet body is additionally provided with temperature detect switch (TDS) 12, the temperature control
Switch 12 and the alarm 13 of 1 top surface of cabinet body are electrically connected.
Specifically, tank for coolant 4 is made of the good metal of heating conduction, such as copper, albronze, to cool down
Liquid case 4 is quickly radiated；The coolant liquid contained in it, can also can guarantee good mobility at low ambient temperatures,
Coolant liquid can be replaced with clear water according to the use environment of cabinet body 1, to reduce manufacture, maintenance cost.Three sides of cabinet body 1,
Top surface, bottom surface are laid with cooling chamber 9, heat-absorbing chamber 10, and heat-absorbing chamber 10 is provided with coolant, and coolant generally selects ammonia, fluorine benefit
High -11 and its of the same clan etc., cooling chamber 9 can contain coolant liquid.Wherein the liquid level in heat-absorbing chamber 10 should be lower than the height of inflator 3
Degree, prevents coolant expanded by heating from entering in inflator 3, preferably 2/3rds of 3 height of inflator, it is ensured that the effect of cooling heat dissipation
While also can guarantee coolant will not enter inflator 3 in；Check valve 11 can prevent coolant liquid when air bag 5 expands, from cold
But chamber 9 bottom enter and can not the steam at the very start to upper end cool down.The lower end of 3 piston 6 of inflator is filled with thermally conductive
Property difference gas, such as inert gas.
Its operation logic are as follows: the coolant in heat-absorbing chamber 10 absorbs the heat given out when electrical component work in cabinet body 1
It expands afterwards and a part flashes to steam, steam enters the upper end inner cavity of inflator 3 by pipeline.And with temperature in cabinet body 1
It increases, the pressure of steam constantly increases that piston 6 is pushed to move down, and by the gas indentation capsule 5 of 3 lower part of inflator, makes
5 swelling volume of air bag is obtained to become larger.Extruding by air bag 5 to coolant liquid in tank for coolant 4, so that coolant liquid is by pipeline from cold
But the top of chamber 9 enters in cooling chamber 9, so that the coolant and its steam to heat-absorbing chamber 10 cool down.To be cooled dose and its
After steam is cooling, the air pressure in heat-absorbing chamber 10 and inflator 3 is reduced, and air bag 5 is shunk at this time, so that the coolant liquid in pipe flows back, is living
Plug 6 resets, 4 pressure of tank for coolant returns to zero.And the coolant liquid in cooling chamber 9 then passes through check valve 11 and is back in tank for coolant 4
(cracking pressure of check valve 11 environment temperature according to locating for cabinet body height and cabinet body is adjusted, the density of coolant liquid and water it is close
Spend close, pressure can be converted into according to liquid level, and unidirectional cracking pressure can accomplish 2kPa or so i.e.), by with it is cold
But the remaining coolant liquid in liquid case 4 is mixed, and is adequately cooled down.
And to enter next cooling cycle, the regular hour is needed, at this time tank for coolant 4 and the sky in ground and environment
Gas carries out heat exchange, can distribute the heat that coolant absorbs.In entire cooling procedure, pass through member electrical in cabinet body 1
The heat acting that part distributes does not consume other energy, therefore entire cabinet body energy conservation and environmental protection.And by the cooling coolant of coolant liquid and
Its steam can quickly and effectively make coolant cooling, to restore the heat absorption capacity of coolant, not need other electric appliances
Element auxiliary；Therefore the rapid heat dissipation of cabinet body 1, good heat dissipation effect, high reliablity.Finally, when temperature will be more than normal range (NR), temperature
Control switch 12 be closed, thus to alarm device 13 energization sound an alarm notify staff replacement coolant liquid or to tank for coolant 4 into
Row cooling improves high reliablity to guarantee direct current cabinet stabilization, reliable work.
Further, the tank for coolant 4 is fixedly connected by column 14 with 1 lower end of cabinet body.That is, tank for coolant
4 and the lower end of cabinet body 1 have a certain distance, air duct is capable of forming, to accelerate the coolant liquid heat dissipation in tank for coolant 4, reduction
The frequency of replacement or cooling coolant liquid, reduces maintenance cost.It also prevents tank for coolant 4 and heat transfer is carried out to cabinet body 1, reduce
The temperature rise of cabinet body 1.
Further, the cavity plate 8 is the thin plate of the continuous convex-concave in surface.It is understood that the use of cavity plate 8 corrugated sheet,
The sheet metal of the continuous convex-concave in the surfaces such as corrugated plating, is capable of increasing the heat exchange area of coolant liquid and coolant, thus more quick
Coolant is cooled down, it is ensured that the efficiency of heat dissipation.
Further, the temperature detect switch (TDS) 12 is mechanical temperature control switch.Specifically, temperature detect switch (TDS) 12 can be vapour pressure
The temperature detect switch (TDS) of the Purely mechanicals such as power formula, liquid expansion type, gas absorption formula, expansion of metal formula, it can be ensured that its temperature control can
By property and accuracy.Simultaneously compared to the temperature controller of electronic type, as resistance power consumption when being only connected, not power consumption when disconnection, more
It is reliable, energy saving.
Further, 3 barrel of inflator is that double-layer vacuum pumping structure or surface are covered with thermal insulation layer.It will be appreciated that
It is that heat-insulated processing is done on 3 surface of inflator, the excessive heat exchange of the steam and extraneous progress after capable of preventing coolant from evaporating, thus
The pressure for reducing steam, so that the coolant liquid into cooling chamber 9 is very few, and cannot be sufficiently cooled cabinet body, coolant；
And then guarantee cooling abundant progress, improve the stability of direct current cabinet work.
Further, the tank for coolant 4 is fitted with thermometer 15.Coolant liquid can be shown in real time by thermometer 15
Temperature, timely to replace, add coolant liquid or to be cooled down to tank for coolant, it is ensured that the cooling efficiency of coolant liquid,
Guarantee the heat dissipation effect of cabinet body.
