Abstract
The utility model discloses a heat radiation type electric control box for mines; the integrated dual-profile structure has the functions of sealed protection and a radiator, and compared with a traditional type, the volume weight ratio of the utility model is greatly reduced. The utility model is characterized in that the outer surface of the periphery of the electric control box body is arranged into a shape with heat radiating fins, and electric power electronic elements and components with large power are directly installed on the inner surface of an upper end cover which is used for sealing and is also used as the radiator in the installation cavity of the box body. The components and parts in the installation cavity are assembled by adopting a dense mode and are sealed by using heat conducting silicone grease and epoxy resin, and the heat quantity generated when the elements, parts or components in use can be transferred to the outer surface having the function of heat radiation of the electric control box.
Description
The electric control box that the utility model relates to a kind of mine and uses down.
The electric control box of down-hole, mine use at present is closed, is made up of element, device installation cavity and wire connection cavity two parts.The electrical control gear of some type has adopted the power electronics high power device or the assembly that can produce a large amount of heats when work, and the large-sized metal heat sink of adapted guarantees normally and reliably working of device or assembly and package unit, therefore needs the electric control box of big assembly space.Metal cabinet is huge and heavy, move and difficult in the down-hole, and the effect that radiator dispels the heat under the condition that is close to sealing is unfavorable, and have no alternative but often reduce rated value and use, application power is restricted.
The purpose of this utility model is to provide a kind of heat dissipation type electric cabinet for the mine, it is except that the sealing safeguard function with the low-pressure electric controlled case in down-hole, mine, the metal cabinet surface also has direct heat sinking function, it is big and heavy to have solved traditional electric cabinet, the dual shortcoming of the radiating effect difference of device and assembly.
The purpose of this utility model be achieved in that mining heat dissipation type electric cabinet by around the outer surface case body and the sealing that are designed to have the heat-dissipating fin shape form with upper end cover with bottom end cover and the double sealing of making radiator.The case body interior is divided into by the power cable of the parts installation cavity of upper end cover sealing and bottom end cover sealing and two cavitys of isolating mutually of control cable wire connection cavity.Power electronics high power device or assembly directly are installed on the inner surface of upper end cover, element, device or assembly and parts in installation cavity are taked the compact mode assembling with heat-conducting silicone grease and epoxy sealing, realize that in the volume that dwindles installation cavity as much as possible element, device or assembly work calories are directly passed to the outer surface of electric cabinet to reach the purpose of heat radiation, thereby reduced weight, save raw material, reduced the consumption of the energy.
The utility model adopts sealing protection and the integrated dual contour structures of radiator, the volume of whole electric cabinet will reduce about 1/2nd than traditional pattern, weight reduces about 3/5ths, the external structure volume is little, integral body is light, carrying is easy, and the work by the dress user of service of will giving bring very big convenience.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the main pseudosection of the mining heat dissipation type electric cabinet of the utility model.
Fig. 2 is a top plan view of the present utility model.
Fig. 3 is a right pseudosection of the present utility model.
The utility model can take following mode to implement: around the inside of mining heat dissipation type electric cabinet body (1) of outer surface with metal casting of heat-dissipating fin (4) be divided into by the outside and have the element of the upper end cover with radiator function (9) of the large tracts of land heat-dissipating fin installed inside high-power unit of good power electronics (19) through bolt (10) fit sealing, the installation cavity of device and parts (2) and by bottom end cover (8) (3) two cavitys of isolating mutually of wire connection cavity through the power cable of bolt (10) fit sealing and control cable, on the outer surface of wire connection cavity (3), be provided with advancing wire hole (5) and advancing wire hole (6) by the power cable (21) of rubber seal (11) metal pressure mouth (12) sealing by the control cable (22) of rubber seal (13) metal pressure mouth (14) sealing, on an outer surface of installation cavity (2), be provided with working state signal observation window (7) by the computer panel (18) of protective glass (15) pressing plate (16) rubber gasket (17) sealing, between (2) two cavitys of isolating mutually of wire connection cavity (3) and installation cavity, leave some through holes (20) conductive lever (23) nut (24) plastic insulation seal washer (25) (26) that is used to pack into and realize being electrically connected of two chambeies, the element of taking compact mode to assemble installation cavity (2) in, device, assembly, element circuit and parts with the heat-conducting silicone grease filling after by epoxy sealing.
