Background technology
At present along with the level of urbanization is more and more higher, monitoring, sky eye, security protection facility are laid, and LED, in the application of advertisement, mark, brightening industry, often can need to use power supply out of doors.For ensureing to use power supply not encroached on by rainwater and dust out of doors, traditional method adopts distribution box, and be careless about the age of outward appearance and convenience, this method follows always.Along with the extensive enforcement of similar engineering, and the pressure of attractive in appearance, cost particularly cost of labor aspect, new technology constantly occurs.
First be waterproof power supply.Power supply seals by waterproof power supply completely, and in inside, filling epoxy resin or silica gel, heat conduction wet goods solid or fluent material, reach the degree of protection of the highest IP68.The waterproof power supply of this structure has the following advantages: 1, protect completely water, dust, worm etc.; 2, fan is not had, without the need to considering fan life; 3, fan-free noise.But equally also have following shortcoming: 1, because radiating condition is limited, when exporting high-power, in order to reduce temperature rise, need very high efficiency, therefore circuit is complicated; 2, based on same reason, the maximum power of waterproof power supply is actually limited; 3, expensive; 4, heavy; 5, can not keep in repair.
What secondly occur in the market is rainproof power supply, and rainproof power supply is very fast after occurring is used widely in engineering.From its thinking, exactly distribution box and power supply are made of one, greatly reduce apparent size.The rainwater that key protection falls, meets the needs of most of engineering.Compared to waterproof power supply, rainproof power supply has the following advantages: 1, cheap, the price of high-power rainproof power supply approximately only has 1/3 to 1/5 of corresponding waterproof power supply; 2, because can adopt fan air blast cooling, power can do very large, fully meets requirement of engineering; 3, lightweight; 4, can keep in repair.But it also has some shortcomings equally: 1, incomplete waterproof, still rainwater can be entered in some cases; 2, dust-proof effect is poor, particularly when there being fan; 3, not insect protected, is easily invaded by mosquito; 4, be limited to fan life, can not the long-life be ensured; 5 fans can bring noise.
According to above-mentioned analysis, rainproof power supply and waterproof power supply respectively have himself shortcoming, limit the application in engineering.Why waterproof power supply is replaced by rainproof power supply to a great extent, its core is that waterproof power supply cannot solve heat dissipation problem, its inside cannot by convection current directly and the external world carry out heat exchange, can only by the limited areal of shell, natural air cooled and the external world is relied on to carry out heat exchange, although some producers arrange radiating fin in case surface, limited efficiency.On the other hand, rainproof power supply just keeps airtight overlooking direction, and lower end allows Cryogenic air to enter, and side has shutter to allow hot-air to overflow usually, or is blown out from the side or below by hot-air with fan.In order to cross-ventilated needs, rainproof power supply cannot seal, thus dust-proof, insect protected is ineffective, waterproof is defectiveness also, particularly evident when sweeping away and pour in down a chimney rainwater.
Summary of the invention
The invention provides the hermetically sealed outdoor power source box of a kind of hung type, be integrated with the advantage of waterproof power supply and rainproof power supply in prior art, this outdoor power system box structure is simple, light, low cost of manufacture, there is good thermal diffusivity, water, dust, worm etc. are protected completely simultaneously; There is no fan, without the need to considering fan life.
Realizing the technical scheme that above-mentioned purpose of the present invention adopts is:
The hermetically sealed outdoor power source box of a kind of hung type, at least comprise shell, described shell is made up of the circuit chamber closed and heat dissipation cavity penetrating up and down, the backboard of aluminum alloy material, side plate, upper cover plate, lower cover, dividing plate and front panel is at least comprised in described shell, wherein upper cover plate, lower cover, backboard, side plate and dividing plate form closed in rectangular-shaped circuit chamber jointly, the top of shell or both sides are provided with the hanger for mounting, and lower cover are provided with the cable-through hole of supply lines turnover; Described dividing plate, side plate and front panel form heat dissipation cavity penetrating up and down jointly, and the distance between dividing plate and front panel is 10 ~ 20mm.

Compared with prior art, combine with multi-cavity structure by suspension is installed in the present invention, whole power supply is divided into circuit chamber and heat dissipation cavity two parts, wherein circuit chamber adopts the structure similar with waterproof power supply, namely circuit part seals completely, but not embedding, namely adopts the degree of protection of IP65.At engineering applications, the degree of protection of IP67 or IP68 is actually a kind of waste, and hang installation and can ensure that power supply can not be soaked in water, and have sufficient protection to rainwater, no matter it is from which direction.Have employed suspended structure in this application, first can prevent power supply box to be placed in the environment of possibility ponding, fundamentally prevents into water; Second is beneficial to the upward motion of air in heat dissipation cavity, effectively forms convection current.The effect of the dowel arranged in heat dissipation cavity and heat dissipation cavity is the heat dissipation problem in order to solve outdoor power system under natural air cooled condition.Wherein the effect of dowel provides one to be more area of dissipations, and two is provide heat conduction between dividing plate and front panel, reduces thermal resistance; Three is be more conducive to form stack effect, accelerates convection current.
In this application, the spacing of dividing plate and front panel is the key of this patent, and the core pathway that multi-cavity structure improves heat radiation provides by front panel the area of dissipation doubling dividing plate.Only when the spacing of front panel and dividing plate is suitable, this mechanism just can play one's part to the full.Too littlely be unfavorable for convection current, too large words increase to the thermal resistance of front panel, pass to the thermal Finite of front panel, are unfavorable for heat radiation.In the ordinary course of things, this spacing gets 10 ~ 20mm.
In this application, due to the existence of multi-cavity structure, it is not merely the increase in area of dissipation, and external heat radiation is accomplished in its most important effect.When circuit because is in the supply powered and produces heat, in traditional outdoor power system, no matter whether adopt fin, the heat that main heater element produces is led on shell.For obtaining area of dissipation as much as possible, these heats can be distributed to as far as possible equably the various piece of shell.The result done like this, area of dissipation is the increase in, but while these area of dissipations and extraneous air carry out heat exchange, also can carry out heat exchange with the inside in circuit chamber.The result done like this is exactly the temperature that the temperature of power source internal is not less than shell.Therefore, in order to not allow internal temperature rise too high, with regard to needing, the temperature of whole shell is controlled in lower level, and the efficiency of heat radiation and shell are directly proportional to the temperature difference of air.The temperature of shell is low, and radiating efficiency is low, reach same heat-sinking capability, needs larger area of dissipation.
But in this application, inside, circuit chamber is no longer the object of heat exchange, heat is introduced to outside circuit chamber, namely front panel get on and extraneous air do heat exchange, heat is led to outside circuit chamber and go to dissipate, as far as possible only and extraneous air carry out heat exchange, to lack and heat exchange is carried out in inside, and multi-cavity structure is the means realizing this innovation.
In sum, the hermetically sealed outdoor power source box of hung type provided by the present invention has the following advantages: 1, relative waterproof power supply, cost greatly reduces.Owing to not adopting the complicated technologies such as embedding, and do not need to lack heating, worry about petty gain or loss in efficiency, total cost greatly reduces, suitable with rainproof power supply.2, heat radiation is good.Multi-cavity structure effectively improves heat radiation, relative single cavity structure, reduces power source internal temperature rise 15 ~ 25 degree, and under making large power supply not have the condition of air blast cooling again, endure, in reduction temperature, can not sacrifice the life-span, breaks through the Power Limitation of waterproof power supply.3, to the degree of protection of rainwater, dust, mosquito far above rainproof power supply.4, do not have fan, the life-span does not restrict by fan, and does not have noise.5, light structure is compact.6, detachably keep in repair.
