Description
Technical field
The utility model relates to explosion-proof electrification application, more particularly, is a kind of explosion-proof electric control box with better heat sinking function.
Background technology
Existing flame-proof type explosion-proof electric cabinet uses limited under the occasion needing radiating treatment because the structure of its opposing seal causes.For this reason by taking different structures, increasing radiating treatment measure and meeting use.Normal practice is as follows: 1, the explosion-proof tank of open sun direct projection installs sunshading board (lid) additional, and sunshading board and explosion-proof tank leave certain ventilation gap, is applicable to the place not high to cooling requirements; 2, Flameproof box cavity space is increased, by increasing the heat radiation of casing self area; The design concept that this kind of mode and Flameproof box are as far as possible little is runed counter to; 3, large-scale explosion-proof tank space is comparatively large, adopts the mode of installing explosion-proof air-conditioner; The method increases the Explosion-Proof of air-conditioning on the one hand, and cost is too high on the other hand; 4, current, what market comparatively accepted is explosion-proof tank to the large components and parts of local pyrexia amount in case, and adopt rear end to add heating panel (sheet), heater element is independently installed on heating panel, take a series of heat transfer, hot swapping, heat is taken out of.5, for big-power transducer, adopt water-cooling pattern to carry out heat exchange process, need to be equipped with a large amount of water treatment auxiliary equipment.
And larger frequency converter adopts the heat dissipation problem of the solution part product that hot pipe technique, forced draft technology, Water Cooling Technology can be economical and practical.But thermal element and heat transfer plate must be combined closely by hot pipe technique, sometimes must break frequency converter original structure, cause electromagnetic interference out of control.For 40KW with low-converter, or when a Flameproof box is installed more than 2 frequency converters or thermal element, adopt the above-mentioned uneconomical practicality of radiating treatment mode.
Utility model content
Because prior art also exists the problems referred to above, the utility model proposes a kind of explosion-proof electric control box, it effectively can solve the problems referred to above of prior art.
The utility model solves the problem by the following technical programs:
