Description
Technical field
The utility model relates to a kind of electrical box of using in air conditioner.
Background technology
First aspect, the electrical box of air conditioner, because of be subjected to fail safe, reliability, manufacturing cost, take up room, the restriction of condition such as heat exchange mode, the structure of the electrical box of selecting for use is comparatively complicated, has following inferior position:
1, processed complex: occupation space is installed for reducing electrical box, generally be designed to two layers, three layers even four layer architectures, supporting producer is assembled into one by spot welding, snap close after must processing respectively when processing again, single-piece will reach higher precision, could assemble closely, have a lot of single-pieces need use die production, the manufacturing cost height, the cycle is long, difficulty is big, and also easy deformation and damage in the transportation.
2, assembling inconvenience: electrical box is in the air conditioner of packing into the time, and because of its complex structure, workload was big when assembling was connected with distribution on production line, and production efficiency is low.In addition, assembling tool is also had higher requirements, instrument can not too greatly maybe need to use profile tool etc.
3, fail safe is low: multilayer circuit board is arranged in the electrical box, on production line during distribution easily because of the wrong line, squeeze line, clamp etc. and cause having an accident in the later stage use.
4, inconvenient maintenance: the complex structure of electrical box makes the maintenance, repair operation comparatively inconvenient.
5, anti-electromagnetic interference is poor: multilayer circuit board is arranged in the electrical box, can not isolate fully before and after the electric component, interfere with each other.Anti-electromagnetic interference performance is poor, needs to increase parts and reduces interference, causes manufacturing cost to rise.
Second aspect, it is very important index in the air-conditioning equipment that electrical box heats up, high-power parts thermal loss is big, if it is bad to dispel the heat, can cause that parts make operation of air conditioner undesired owing to temperature is higher.The tradition air conditioner adopts the outdoor heat exchanger fan to reduce the electrical box temperature when reducing heat exchange temperature, though provide cost savings like this, but the rotating speed of heat exchanger fan control is according to the heat exchange effect decision of heat exchanger, and it is irrelevant with the electrical box temperature, temperature is prone to fluctuation in the electrical box, influences the useful life of parts.
The 3rd aspect enters for preventing rainwater, and the main heat dissipation direction of electrical box must seal, thereby increased the workload of assembling electrical box, and has the bad hidden danger that causes the circuit element short circuit of sealing.
The utility model content
The purpose of this utility model is to provide a kind of novel electrical box of use in refrigeration system, and this novel electrical box has simple in structure, cheap for manufacturing cost, the advantage that thermal diffusivity is good.
The utility model for achieving the above object, the technical solution of employing is:
The novel electrical box of use in refrigeration system comprises box body, and configuration seal cover in box body top has air inlet on the front side wall of box body and the rear wall, and the base plate of box body is provided with the fan to the plate outer side air draft.
Said fans is positioned at the middle part of base plate, and the below of fan is provided with the air channel, and the right side of base plate has an opening to communicate with the air channel, and the air outlet in air channel is positioned at the right side wall below of box body, and towards right-hand.
Above-mentioned duct cross-section is a rectangle, and the opening on base plate right side is a rectangle, and the air channel has discharge outlet near on the lower wall panels of air outlet.
In the above-mentioned box body circuit board is housed, the direct current forceful electric power circuit of circuit board is positioned at the fan right side, and the back of direct current forceful electric power circuit is provided with radiator, and radiator stretches in the air channel; The interchange forceful electric power circuit of circuit board is positioned at the fan left side, is the T type and distributes; The light current circuit of circuit board is positioned at the lower left that exchanges the forceful electric power circuit.
The top of above-mentioned front side wall and rear wall is flange laterally all.
The left side wall of above-mentioned box body leaves the opening of being convenient to the distribution cabling.
The beneficial effects of the utility model:
1, configuration aspects, the novel electrical box of use in refrigeration system adopts single layer structure.Box body top configuration seal cover, the below, right side of base plate is provided with the air channel, and structure is tighter.Circuit element is plane figure, and is not overlapping, is arranged in order by the circuit trend, and circuit element comes into plain view in the whole electrical box.It is convenient not only to install, dismantle electric component, and the whole electrical box of installation or removal is also very simple, and electrical box is installed and do not needed by suspender, and a people is light carrying and installation just.
2, heat radiation and waterproof aspect have air inlet on front side wall and the rear wall, and the baffle plate protection also is equipped with in the air inlet outside, and baffle plate mainly has been the effect of supporting electrical box, prevents into water simultaneously again.On the base plate of electrical box fan is housed, hot-air is discharged by the air channel in the electrical box, again the radiator that stretches into the air channel is dispelled the heat simultaneously.
3, electromagnetic interference aspect, according to voltage characteristic, with forceful electric power, light current, direct current, interchange parts zoning, do not intersect, not repeatedly, the more compressor power line of interference signal is directly drawn with the shortest distance from electrical box one side and is arrived compressor, thus effectively reduce between the circuit element, between the forceful electric power light current, the phase mutual interference between the distribution.
