Abstract
The utility model relates to an electric appliance cabinet, particularly a resistance cabinet which is provided with a wind guiding board which can guide wind and radiate heat. The utility model comprises a top cover, a box body and a resistance element. The utility model is characterized in that the wind guiding board is arranged between the upper part of the box body and the top cover, and the wind guiding board is provided with a wing part which inclines and extends to two sides, or the upper part of circumference from the middle part. The utility model solves the technical problem that an apparatus is overheated under the condition of natural ventilation.
Description
Technical field:
The utility model is about the electrical equipment bin, particularly about the resistor box of the wind deflector that is provided with air inducing heat radiation.
Background technology:
Resistor box is the support device of rane trolley and miscellaneous equipment, owing in the cabinet resistive element is installed, the resistive element heating influences power with the restraint of labour electric current at work.Existing for this reason resistor box between top cover and casing, be provided with one with the extraneous passage A that communicates, (seeing shown in Figure 1), this passage A is surrounded by the sidewall lower edge of top cover 1 upper limb to casing 2, the air that heated by resistive element rises to turns back after case lid is obstructed, be forced to discharge, the heat that resistive element produced is taken out of outside the resistor box from this passage A.Its advantage of the radiating mode of this prior art is simple in structure, but from the fluid mechanics commercial weight, the direction of motion of its thermal air current is two 90 ° right angle variation, the resistance of motion is big, under the condition that does not have the additionaling power natural draft, its flow velocity must be restricted and descend, thereby influence radiating efficiency, therefore equipment is easy to generate superheating phenomenon in actual use, particularly the operating time one is grown, and situation is just more serious, especially the top of resistor box, because the heat synergistic effect that the structure that the resistive element multilayer is arranged produces, superheating phenomenon more very.For solving this problems of excessive heat, existing technology often is provided with electric fan, takes the forced ventilation method, accelerates air-flow velocity, though this mode is effective, causes that the rising of equipment cost and the consumption of the energy increase.
Summary of the invention:
The purpose of this utility model is to provide a kind of resistor box with wind deflector, solves the overheated technical problem of equipment appearance under the natural draft condition.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of resistor box with wind deflector comprises top cover, casing and resistive element, it is characterized in that: be provided with wind deflector above the casing and between top cover, this wind deflector be provided with by the centre respectively to both sides or all around the top slant dilation alar part.
It is characterized in that: this alar part is plane or cancave cambered surface.
It is characterized in that: the sidewall of this top cover is provided with air vent hole.
The utlity model has following beneficial effect:
1) the resistive element temperature rise with power descends more than 10%, overcomes superheating phenomenon effectively.
2) the heat energy superposition phenomenon of levels resistive element in minimizing and the alleviation cabinet.
3) under condition with power, can reduce the quantity of resistive element less, reduce cost.
4), can dwindle the volume of casing, the consumption of having saved tank material owing to the minimizing of resistive element quantity.
5) only need increase wind deflector for existing product and get final product, and original parts can not made any changes, original moulds of industrial equipment still can use, the less investment of technological transformation, last detective.
6) needn't set up fan, rely on the natural ventilation system of convection current conduction, the energy resource consumption of having save the input of ventilation equipment and having saved ventilation equipment.
Description of drawings:
Fig. 1 is the structural representation of existing electricity group cabinet.
Fig. 2 is a kind of structural representation of the present utility model.
Embodiment:
See also shown in Figure 2ly, the utility model comprises top cover 1, casing 2 and resistive element 3, these top cover 1 both sides or sidewall lower edge all around and casing 2 corresponding on intermarginally have a space, this space is the passage A of hot-airs outflow in the casing 2.The several layers of resistive element 3 that are intervally installed up and down in this casing 2, this resistive element 3 is connected for insulation with the casing 2 of metal.Between above this top cover 1 and the casing 2, be provided with wind deflector 4, this wind deflector 4 has by the centre to both sides or the alar part 41 that tilts all around and stretch upwards, this alar part 41 can be the plane, it also can be cancave cambered surface, outer rim at this alar part 41 is extended with fixed part 42, and this fixed part 42 of nationality is fixed on this wind deflector 4 in the top cover 1.The alar part 41 of this inclination can change in 0 ° of-90 ° of scope with the angle of horizontal plane, usually alar part 41 this angle α concerning the plane are advisable with 20 ° of-70 ° of scopes, its radiating and cooling in 30 ° of-45 ° of scopes, the overall structure size is with combination property the bests such as material consumption.
In the work, air in the casing 2 is subjected to the thermal expansion that adds of resistive element 3, density reduces and forms the thermal current of rising, when it rises to after wind deflector 4 contacts, because the inclination of wind deflector 4 produces the component that moves along alar part 42 surfaces, promote this thermal current to both sides or mobile all round, greatly reduce the resistance that thermal current flows, the thermal current change in flow is very little.For giving full play to this creative ideas of the utility model, can offer air vent hole facing on the sidewall 11 of thermal current flow direction at top cover 1, increase the passage of thermal current slight drag outflow.
