Abstract
The utility model relates to a mine variable-frequency governor with external cooling device and comprises a mine variable-frequency governor, a cooling device is arranged outside the heating elements of the mine variable-frequency governor and comprises a heat sink plate and a cooling water sleeve; the heat sink plate is fixed on the heating elements, and the cooling water sleeve is fixedly connected with the heat sink plate. The utility model has the beneficial effects that the heat sink plate and the cooling water sleeve are arranged outside the main heating elements to carry the heat produced by the electric elements away with cooling medium by forced flow, thus realizing the control on the working temperature of the main electric heating elements and prolonging service life of the elements; the external cooling device eliminates irresolvable potential fault hazards of inner cooling device, solves problems existing in the prior art, and enhancing the safety of the electric system.
Description
Technical field
The utility model relates to a kind of variable-frequency governor, relates in particular to a kind of mining variable-frequency governor that has external cooling device.
Background technology
At present mine explosion-suppression variable-frequency governor methods for cooling has multiple: natural wind cold mould, air blast cooling type, natural air cooled and air blast cooling mating type, Forced water cooling type; The Forced water cooling type is because good cooling results, compact conformation, and volume is little, has been subjected to people's common concern, but water-cooling system in the market mostly is built-in, this built-in mode, and leaking causes fault easily, the maintenance of cooling system is also very inconvenient simultaneously.
The utility model content
The utility model is to overcome above-mentioned weak point, purpose is to provide a kind of mining variable-frequency governor that has external cooling device, outside the electric main heater element of mining variable-frequency governor, be provided with heating panel, cooling jacket, the heat that electric component produced is taken away its heat by forced flow by coolant, thereby realize control to main electric heater element working temperature, improved the useful life of element, the cooling device of this external has been eliminated the potential faults that can not solve of the built-in existence of cooling device, has solved problems of the prior art.
The utility model is to achieve the above object by the following technical programs: a kind of mining variable-frequency governor that has external cooling device, comprise mining variable-frequency governor, be provided with cooling device outside on the heater element of mining variable-frequency governor, described cooling device comprises heating panel, cooling jacket; Described heating panel is fixed on the heater element, and cooling jacket is fixedlyed connected with heating panel.
As preferably, heater element, heating panel scribble heat conductive silica gel on cooling jacket three's the faying face, again with the screw connection that is fixed respectively.
As preferably, heating panel is the heating panel that fine copper is made.
As preferably, cooling jacket is the cooling jacket that aluminum alloy materials is made.
As preferably, the coolant in the cooling jacket is a water.
As preferably, the coolant in the cooling jacket be oily.
The beneficial effects of the utility model: be provided with heating panel, cooling jacket outside on main heater element, the heat that electric component produced is taken away its heat by forced flow by coolant, thereby realize control to main electric heater element working temperature, improved the useful life of element, the cooling device of this external has been eliminated the potential faults that can not solve of the built-in existence of cooling device, solve problems of the prior art, strengthened the fail safe of electrical system.
Description of drawings
Fig. 1 is a kind of structural representation of external cooling device of mining variable-frequency governor;
Embodiment
The utility model is further elaborated by embodiment below in conjunction with accompanying drawing:
Embodiment 1: as shown in Figure 1, a kind of mining variable-frequency governor that has external cooling device comprises mining variable-frequency governor, is provided with cooling device outside on the heater element 1 of mining variable-frequency governor, and described cooling device comprises heating panel 2, cooling jacket 3; Heater element 1, heating panel 2 scribble heat conductive silica gel on cooling jacket 3 threes' the faying face, again with screw 4,5 connection that is fixed respectively.Heating panel 2 is made for fine copper, and cooling jacket 3 is made for aluminum alloy materials, and the coolant in the cooling jacket 3 is water or oil.
During actual the use, with heater element 1, heating panel 2, cooling jacket 3 threes fasten as one with screw 4,5 by shown in Figure 1, should be coated with heat conductive silica gel at the corresponding faying face of each element place before fastening,, get final product on the supporting explosion-resistant enclosure of then its system being packed into to guarantee the heat conduction reliability.The heat that electric component produced is taken away its heat by forced flow by coolant, thereby realize control to main electric heater element working temperature, improved the useful life of element, the cooling device of this external has been eliminated the potential faults that leaks that can not solve of the built-in existence of cooling device, solve problems of the prior art, strengthened the fail safe of electrical system.
Above described be specific embodiment of the utility model and the know-why used; if comply with the change that conception of the present utility model is done; when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, must belong to protection range of the present utility model.
