Abstract
The utility model discloses a radiating device of an embedded reactor, comprising a box-type casting, radiating fins and a connecting cover plate, wherein the radiating fins are arranged on the left side, the right side and the rear side of the box-type casting; the front opening of the box-type casing is fixedly connected with the connecting cover plate which is provided with a hole matched with a reactor and a terminal of the reactor; the periphery of the connecting cover plate is also distributed with installing holes uniformly; the box-type casting is of a cuboid and is made of aluminium; the radiating fins are aluminium piece type radiating fins; and heat-conducting silica gel is poured in the gap between the inner peripheral wall of the box-type casting and the reactor. The radiating device of the embedded reactor has the benefits of capability of improving the working efficiency of a proof mining filtering device and low cost.
Description
Technical field
The utility model relates to a kind of heat abstractor of power electronic equipment, relates in particular to a kind of embedded reactor heat abstractor that is applied to the mine explosion-suppression filter.
Background technology
Along with the continuous development of computer and microelectric technique, the automation and the level of informatization of coal production equipment also improve constantly, and its product has obtained using widely under coal mine.Owing to exist a large amount of explosibility gas CH4 and CO under the coal mine, thus require to make explosion-proof form for these power electronic equipments, yet like this its heat radiation has just been brought very big unfavorable.The rising of ambient temperature can make material property degradation, causes the electronic component failure rate to increase.In the thermal design process, to take measures the temperature rise in restrictor device and the cabinet at first exactly.Its principle one is to reduce caloric value, the 2nd, strengthen heat radiation, and comprise the design of heat abstractor, air-cooled design, liquid cools design etc.
Existing mine explosion-suppression filter, be with the components and parts device in cabinet, the heat that produces during with the work of inner components and parts by forms such as heat pipe or heat exchangers is transmitted to outside the cabinet, dispels the heat.And one of higher device of heat during the heating of reactor to be it inner components and parts work is resolved the heat dissipation problem of reactor, is the key of improving the filter cavity temperature.Heat when the reactor in the existing mine explosion-suppression filter is worked can not directly shed outside the cabinet, cause explosion-proof cabinet cavity temperature too high, influence the life-span and the operate as normal of components and parts, need to drop into the heat dissipation problem that higher cost (as, water-cooled etc.) solves reactor.The radiator structure of at present domestic habitual feedback reactor, general all is the shell that welds with steel plate, on shell, weld some fin then, can play some effects like this, but do not reach desirable state far away, influenced the normal operation of equipment, brought difficulty to the safe and highly efficient operation of entire job system under the coal mine.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can improve mine explosion-suppression filter operating efficiency and good heat dissipation effect, cheap embedded reactor heat abstractor.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of embedded reactor heat abstractor, and it is made up of boxlike foundry goods, fin and connection cover plate; Described fin is installed in the left and right sides and the rear side of described boxlike foundry goods, and the prosopyle place of described boxlike foundry goods is connected with the connection cover plate.
Described connection cover plate is provided with and reactor and the suitable hole of reactor binding post, also is evenly equipped with installing hole on the periphery of described connection cover plate.
Described boxlike foundry goods is a cuboid, and the material of described boxlike foundry goods is an aluminium; Described fin is an aluminum chip fin.
Irritate in gap between the internal perisporium of described boxlike foundry goods and the described reactor heat conductive silica gel.
Adopt the beneficial effect that technique scheme produced to be:
(1) can be mounted on outside the explosion-proof cabinet owing to this embedded reactor heat abstractor, a large amount of heats that reactor produces during equipment work, can conduct timely fast, be dispersed in the extraneous air, this radiating mode safety, simple and reliable, can further improve equipment operation condition like this, avoid having influence on operate as normal and its life-span of reduction of other components and parts of device interior owing to the heat of big heat device reactor.
(2) this embedded reactor heat abstractor design cost than the heat abstractor of other form is lower, can be widely used economic and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1, left fin; 2, right fin; 3, back fin; 4, boxlike foundry goods; 5, connect cover plate; 6, reactor binding post; 7, reactor; 8, installing hole
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to accompanying drawing 1, be connected with at the prosopyle place of described boxlike foundry goods 4 and connect cover plate 5, described connection cover plate 5 is provided with the hole suitable with reactor 7 and reactor binding post 6, and described and reactor 7 and reactor binding post 6 suitable holes are communicated with; Reactor 7 is embedded in the boxlike foundry goods 4, and described reactor binding post 6 hole place suitable with it on described connection cover plate 5 extends out, and in the internal perisporium and the filling of the gap between the described reactor of described boxlike foundry goods heat conductive silica gel arranged; The left and right sides and rear side at boxlike foundry goods 4 are equiped with left fin 1, right fin 2, back fin 3 respectively, increase its area of dissipation with this; Also be evenly equipped with installing hole 8 on the periphery of described connection cover plate 5.This embedded reactor heat abstractor is contained in mine anti-explosion cabinet outside by installing hole 8.The a large amount of heats that produced when reactor 7 work operations at first conduct by the boxlike foundry goods 4 of aluminum like this, the fin of the aluminum chip of its left and right sides of process and rear side directly is dispersed into heat in the extraneous air then, other components and parts in the mine anti-explosion cabinet can better be worked like this, have prolonged its working life.
Claims (4)
1. embedded reactor heat abstractor is characterized in that it is by boxlike foundry goods, fin and connect cover plate and form; Described fin is installed in the left and right sides and the rear side of described boxlike foundry goods, and the prosopyle place of described boxlike foundry goods is connected with the connection cover plate.
