Abstract
An electric control box used for a powder shaping machine comprises a box body (1) and a heat exchanger (2) arranged at the side of the box body (1); the upper part and the lower part of the box body (1) are respectively provided with an air inlet (11) and an air outlet (12); while the side surfaces of the heat exchanger (2) are respectively provided with an inner circulation outlet (21) and an inner circulation inlet (22) correspondingly; the inner circulation outlet (21) and the inner circulation inlet (22) rightly aims at the air inlet (11) and the air outlet (12) of the box body (1); the inner circulation outlet (21) is provided with a first fan (3); the bottom part of the heat exchanger (2) is provided with an outer circulation inlet (23) and the top part is provided with an outer circulation outlet (24); the outer circulation outlet (24) is provided with a second fan (4). The utility model can effectively lower the work temperature of the electric control box and avoids floating dust entering the inside of the box body to besmirch the components in the box body in the mode of additionally arranging the heat exchanger outside the box body; therefore, the electric control box has the advantages of good dustproof effect and capability of providing the component with good work environment.
Description
Technical field
The utility model relates to the technical field of powder forming machine, especially refers to a kind of electric control box that is used on the powder forming machine.
Background technology
Powder forming machine is a kind of equipment of electromechanical integration, electric control box wherein is the significant components of powder forming machine, because of having concentrated control device and Electric Traction device in the electric control box, these devices all will generate heat when real work, especially powerful frequency converter, its caloric value is quite big, and many electric components all have strict requirement for the temperature of operational environment.At present, for solving the cooling problem of electric control box inside, generally be on the casing of electric control box, to offer shutter or air-vent, some sets up ventilating fan again to improve radiating rate in casing, but the powder forming machine at electric control box place, its raw material of processing is a powdery, whole electric control box all is in the operational environment of floating dust, the electric control box that has the hole is after the medium-term and long-term use of this environment, floating floating dust all can enter box house, and is deposited on the electric components in the casing, particularly for the electric control box that ventilating fan is installed, because the air draught effect of ventilating fan, floating dust very easily can be inhaled in the casing, and the floating dust of these accumulations is difficult to thoroughly remove clean, is unfavorable for very much the operate as normal of electric components, burnout failure also takes place easily, makes electric control box have bigger potential safety hazard.Therefore, the cooling method of the electric control box of this easy pollution internal components requires further improvement.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of electric control box on the powder forming machine of being used for that can effectively reduce the working temperature of electric control box and be difficult for besmirching electric components in the casing, have dustproof effect is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the electric control box on the powder forming machine, include casing, it is characterized in that: also include the heat exchanger that is arranged on casing one side, upper and lower in that side of casing that is provided with described heat exchanger, have air inlet and air outlet, and the side of described heat exchanger corresponding respectively have in loop exit and interior circulation import, air inlet and the air outlet on the described casing just in time aimed in interior loop exit on this heat exchanger and interior circulation import respectively, and, loop exit is provided with first fan in this, the bottom of this heat exchanger has the outer circulation import, the top has the outer circulation outlet, also is provided with second fan in this outer circulation outlet.
For strengthening the radiating effect of heat exchanger, described heat exchanger inside can also be provided with the heat-exchange tube that at least one two-port is connected with outer circulation import and outer circulation outlet respectively, and the tube wall of each heat-exchange tube also is distributed with a plurality of fin outward, like this by a plurality of fin, increase area of dissipation, can increase substantially the radiating effect of heat exchanger.
Compared with prior art, advantage of the present utility model is: by heat exchanger the hot-air in the electric control box is sucked heat exchanger and cool off, air after the cooling enters in the casing of electric control box by interior loop exit again, thereby form the cooling system of a reciprocation cycle, effectively reduce the working temperature of electric control box, and by the mode of heat exchanger is set outside the casing of electric control box separately, make the casing of electric control box still be in sealing state basically, avoid the floating dust in the powder forming machine to enter box house and besmirched electric components in the casing, have the good dust-proof effect, guarantee to offer good working environment of electric components; In addition, heat-exchange tube and fin are set, have further strengthened the radiating effect of heat exchanger in heat exchanger inside, very practical; The utility model is simple in structure, is easy to manufacture, and is suitable for practical application.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1～shown in Figure 4, the electric control box that this is used on the powder forming machine includes casing 1 and is arranged on heat exchanger 2 on casing 1 one sides;
Wherein, upper and lower in casing 1 that side that is provided with described heat exchanger 2, have air inlet 11 and air outlet 12, and the side of heat exchanger 2 corresponding respectively have in loop exit 21 and interior circulation import 22, air inlet 11 and the air outlet 12 on the casing 1 just in time aimed in interior loop exit 21 on this heat exchanger 2 and interior circulation import 22 respectively, and, loop exit 21 is provided with first fan 3 in this, the bottom of this heat exchanger 2 has outer circulation import 23, the top has outer circulation outlet 24, also is provided with second fan 4 in this outer circulation outlet 24;
And described heat exchanger 2 inside also be provided with eight two-port respectively with outer circulation import 23 and outer circulation outlet 24 heat-exchange tubes that are connected 25, and the tube wall of heat-exchange tube 25 also is distributed with a plurality of fin 25a outward.
During work, starting fan, hot-air in the electrical control box body 1 is by the air outlet 12 on the casing 1, interior circulation import 22 on the heat exchanger 2 and entering within the heat exchanger 2, and the cold air that circulates on the path between outer circulation import 23 and the outer circulation outlet 24 arranged in the heat exchanger 2 all the time, hot-air within the heat exchanger 2 fully carries out heat exchange with the cold air of constantly circulation like this, thereby reach the purpose of heat of cooling air, like this, hot-air after the cooling is just by interior loop exit 21 on the heat exchanger 2, air inlet 11 on the casing 1 and coming back in the electrical control box body 1 is realized then to the effective purpose of cooling in electric control box inside.
