In view of above-mentioned prior art; Be necessary the version of existing circuit breaker drawer base is improved, for this reason, the applicant has carried out good try; Found the way that solves the problems of the technologies described above, the technical scheme that will introduce below produces under this background
Summary of the invention
The purpose of
the utility model is that a kind of circuit breaker drawer base with radiating effect will be provided, and it can reduce the internal temperature of circuit breaker drawer base, guarantees that the drawout chassis internal part can operate as normal.
The purpose of
the utility model reaches like this; A kind of circuit breaker drawer base with radiating effect comprises base plate, side plate, pedestal and top cover, and the below of said base plate is equipped with a pair of mounting bar; The both sides of said base plate are separately installed with side plate; The top of pair of side plates is equipped with top cover, and described pedestal is installed between base plate and the top cover and is fixed on the rear side of pair of side plates fore-and-aft direction, and this pedestal comprises and touches bridge and base body; Described touching in the inside die cavity that bridge is installed in base body, be characterized in: said base plate is provided with first air vent hole.
In a specific embodiment of the utility model, described first air vent hole has a plurality of, interruption-like being distributed on the base plate
.
The 3rd air vent hole is offered in
on the base body of described pedestal in another specific embodiment of the utility model.
are in another specific embodiment of the utility model; Described base body is fixed on the pair of side plates through a top-support; On described top-support, offer second air vent hole, the position of described second air vent hole is corresponding with the position of described the 3rd air vent hole.
also have in the specific embodiment the utility model, offer the four-way pore on the described top cover.
the utility model is because after adopting technique scheme; The beneficial effect that has: at first; Owing on base plate, offered first air vent hole, made that can suck cold air from the below of base plate is used for heat radiation, thereby can reduce the internal temperature of circuit breaker drawer base; Secondly, through the 3rd air vent hole of on base body, offering, make the inner air-flow of circuit breaker drawer base to flow through and touch bridge, thereby can further reduce the internal temperature of circuit breaker drawer base; At last; Can form convection current with the circuit breaker drawer base extraneous air through first air vent hole, second air vent hole, the 3rd air vent hole and four-way pore; Thereby can further reduce the internal temperature of circuit breaker drawer base, guarantee that the drawout chassis internal part can operate as normal.
Description of drawings
Fig. 1 is the prior art constructions sketch.
Fig. 2 is an example structure figure of the utility model.
Among
figure: 1. base plate, 11. first air vent holes, 12. mounting bars; 2. side plate; 3. pedestal, 31. touches bridge, 32. base bodies, 321. top-supports, 3211. second air vent holes, 322. the 3rd air vent holes; 4. top cover, 41. four-way pores.
Embodiment
can be expressly understood the technical spirit and the beneficial effect of the utility model more for the auditor that the makes Patent Office especially public; The applicant general elaborates with the mode of embodiment below; But the description to embodiment all is not the restriction to the utility model technical scheme, any according to the utility model design done only for pro forma but not substantial equivalent transformation all should be regarded as the technical scheme category of the utility model.
