The specific embodiment
(first embodiment)
With reference to Fig. 1 one first embodiment is described below.Fig. 1 is the sectional view of signal that constitutes the outdoor unit of an air conditioner.
The shell 1 of one unit main body of structure outdoor unit is provided with a horizontal baffle 2, and it is located substantially on mid portion vertically, and with horizontal baffle 2 inside of shell 1 is separated into upper and lower compartment.The enclosure of horizontal baffle 2 tops is referred to as heat exchanger chambers 3, and the enclosure of horizontal baffle 2 belows is referred to as machine chamber 4.
In machine chamber 4, be furnished with one gas-liquid separator 7, a compressor 8, and shown in valve, pipeline etc.Compressor 8 grades are communicated with the coolant hose of outdoor heat converter 5, so that constitute a cool cycles, in addition, coolant hose extends to the indoor heat converter of a formation indoor unit (not shown).
One electric part box 9 that holds electric component C etc. also is arranged in the machine chamber 4 together with compressor 8.As the electric component C that is contained in the electric part box 9, for instance, one electric component with relatively little caloric value (wiring board) C1 that the electronic component of control is installed on it is arranged in upper side, and the electric component with big relatively caloric value (wiring board) C2 such as a converter circuitry is arranged in lower side.In addition, a electric component with extremely big caloric value etc. such as the reactor (not shown) also is contained in wherein.
At the electric component C2 place with big relatively caloric value such as a converter circuitry, a radiator 10 is attached to the back side integratedly, and outstanding from the side plate 9a that constitutes electric part box 9.Radiator 10 is made up of a plurality of cooling fins made from the outstanding material of heat dissipation characteristics, and such material is aluminum for example, and cooling fins is along the vertical direction setting, so that have a predetermined space along the depth direction on the paper.
A plurality of air are introduced hole 11 and are formed in the base plate 9b of electric part box 9, and an outside air inlet hole (not shown) is formed in the part of Shell Plate 1a, and its intention is to move apart the position that air is introduced hole 11.In addition, a cooling pipe 12 carries out attached along the therefrom outstanding side plate 9a of the radiator 10 of electric part box 9.It is U-shaped (as shown in plane) that cooling pipe 12 forms a cross section.The peripheral part of opening wide is towards the side plate 9a of electric part box, and is attached and be fixed to the side plate 9a of electric part box along a bead unit of edge setting.
One air-vent 13 is formed on the part place towards cooling pipe 12 tops at the side plate 9a place of electric part box 9, and the inside of the inside of electric part box 9 and cooling pipe 12 communicates with each other by air-vent 13.One is projected into the circumferential section setting of the mouth body 14 of cooling pipe 12 along air-vent 13, and the end of mouth body 14 covers to have a predetermined space with a cover member 15.
Therefore, be incorporated into the air of air-vent 13 from electric part box 9 inside, be directed to the mouth body 14 that is provided with along the circumferential section of air-vent 13, and in electric part box 9, derive.Then, air circulation flows along the space between cover member 15 and the electric part box side plate 9a by the space between mouth body 14 ends and the cover member 15, imports at last in the cooling pipe 12.
The outdoor unit of air conditioner so constitutes, when one drives the command signal input, compressor 8 is driven, so that a cooling medium is incorporated into outdoor heat converter 5, all valves, gas-liquid separator 7, and in the indoor heat converter in the indoor unit, this realizes the operation of a cool cycles.Simultaneously, outdoor fan 6 is driven and outside air is drawn in the heat exchanger chambers 3.Outside air cycles through outdoor heat converter 5 so that carry out heat exchange, and in addition, air is discharged to the outside by outdoor fan 6.
The air blast effect of outdoor fan 6 allows heat exchanger chambers 3 to be in negative pressure, and this influence arrives the cooling pipe 12 that is communicated with heat exchanger chambers 3, like this, makes the inside of cooling pipe 12 also be in negative pressure.The outside air of shell bottom plate 1a outside sucks from the shell bottom plate opening 12b of cooling pipe 12, and circulates cooling pipe 12 in and export to heat exchanger chambers 3 from the opening 12a that is formed in the horizontal baffle 2.
The intermediate flow that outside air circulates in pipeline 12 contacts radiator 10 and carries out heat exchange each other.Be transferred to the outside air of the heat radiation of radiator 10 to circulation in cooling pipe 12 from the electric component C2 with big caloric value such as a converter circuitry, electric component C2 is cooled together with radiator 10.The heat of electric component C2 is difficult to be radiated the inside of electric part box 9 and the inside of machine chamber 4, and this can suppress the rising of temperature.
Because cooling pipe 12 is attached along the side plate 9a of electric part box 9, so the outside air of circulation leads along electric part box side plate 9a in cooling pipe 12.Therefore, cooled off by outside air towards the part (side plate 9a) of the electric part box 9 of cooling pipe 12.
In addition, when making the inside of cooling pipe 12 become negative pressure by drive chamber's external fan 6, the inside of the electric part box 9 that is communicated with cooling pipe 12 also becomes negative pressure by air-vent 13.Under this effect effect, the air in the machine chamber 4 is directed in the electric part box 9 from the air introducing hole 11 that is formed in the electric part box 9 base plate 9b.Air in the machine chamber 4 is the outside air that imports by an outside air inlet hole (not shown) that is formed in the shell bottom plate 1a, and in fact, the fresh and low outside air of temperature imports in the electric part box 9.
From the air of electric component box plate 9b introduce hole 11 import in the electric part box 9 outside airs directly contact be contained in electric component C1 and C2 in the electric part box 9, and all parts are cooled off.The outside air that temperature rises by cooling is derived from the air-vent 13 that is formed on electric part box 9 tops, and is led and be directed in the cooling pipe 12 by mouth body 14 and cover member 15.
As mentioned above, the air after the cooling radiator 10 circulates in cooling pipe 12, in the air inflow cooling pipe 12 by air-vent 13 guiding.The air that confluxes is directed in the heat exchanger chambers 3, and further is discharged to the outside by the effect of outdoor fan 6.
Like this, the radiator 10 that is attached to electric component C2 is projected into cooling pipe 12 inside, and electric component C2 has big caloric value, such as converter circuitry, and the be cooled outside air cooling of circulation in the pipeline of radiator 10.Towards the be cooled outside airs cooling of circulation in the pipeline 12 of the electric part box side plate 9a of cooling pipe 12.Electric component C2 and C1 in the electric part box 9 are directly cooled off by the cooling air that the introducing hole 11 from electric component box plate 9b is directed to the inside of case 9.
Outside air is cooling radiator 10, electric part box side plate 9b respectively, and after electric component C2 and the C1, be discharged to the outside by heat exchanger chambers 3, and the fresh and low outside air of temperature is incorporated into radiator 10, electric part box side plate 9a all the time, and in electric component C2 and the C1.Therefore, can suppress the rising of electric part box 9 internal temperatures reliably, this realizes the cooling to electric component C2 and C1 effectively, and can obtain the very big improvement of cooling effectiveness.
In addition, the outside air at place, shell bottom plate 1a outside imports in the cooling pipe 12.Reason no matter rain how severely, does not all have water droplet can arrive the shell bottom plate opening 12b of cooling pipe 12 from the space between shell bottom plate 1a and the shell mounting plane G for this reason, is difficult to more imagine that having water droplet is penetrated in the cooling pipe 12 therefrom.
Supposing has such situation, wherein, is penetrated in the cooling pipe 12 such as the water droplet of rainwater etc., thereby is blended in the outside air.Most water droplet collides with radiator 10 after entering into cooling pipe 12 immediately, therefore, can not further be penetrated into inside.Even water droplet is by radiator 10, when the upper end open 12a of its cooling pipe in being formed on horizontal baffle 2 entered heat exchanger chambers 3, water droplet also can be drawn.The outdoor heat converter 5 that is arranged in the heat exchanger chambers 3 is configured to: even rainwater is poured into heat exchanger itself, also can not break down.Its result can not break down even water droplet is penetrated in the heat exchanger chambers 3 from cooling pipe 12 yet.
According to such situation, can expect that some water droplet by radiator 10 is penetrated in the space between the electric part box side plate 9a of cover member 15 and cooling pipe 12 tops.Yet, being penetrated into the water droplet that covers in the space of member 15 and colliding on the mouth body 14, mouth body 14 is arranged to just give prominence to from its back along the circumferential section of air-vent 13, further limits its infiltration thus.Mouth body 14 has the function of a so-called baffle plate, and it causes not having the water droplet amount can arrive air-vent 13.Need not go into the details, do not have water droplet to be penetrated in the electric part box 9 from the air-vent 13 under the negative pressure state.
Outside air is introduced hole 11 from the air of electric component box plate 9b equally and is imported.Yet as mentioned above, air is introduced hole 11 and is formed on the position that distance is formed on the outside air inlet hole in the shell bottom plate 1a.If water droplet is penetrated into enclosure from the outside air inlet hole, then do not have water droplet to arrive air and introduce hole 11 from the outside air inlet hole, thus, water droplet will never be introduced hole 11 from air and be penetrated in the electric part box 9.Therefore, can limit the short circuit accident of electric component C2 and C1 reliably.
(second embodiment)
Next, with reference to Fig. 2 the second embodiment of the present invention is described.Because the entire infrastructure of outdoor unit is identical with structure among above-mentioned Fig. 1 basically, therefore, utilizes and to omit extra description it to its diagram.Fig. 2 is the schematic section of the amplification of electric part box 9 and its periphery.
The electric part box 9 that holds electric component C1 and C2 etc. is arranged in the machine chamber 4.One radiator 10 is arranged to be attached to integratedly the electric component C2 with big caloric value, and outstanding from an electric part box side plate 9a.Air is introduced hole 11 and is formed in the electric component box plate 9b, and cooling pipe 12 is attached from wherein outstanding side plate 9a along radiator 10.
Here, have and be characterised in that, one dividing plate 20 is set, it separates the inside that air-vent 13 is formed on the side plate 9a and the electric part box 9 of electric part box 9 wherein, its feature also is, dividing plate 20 is provided with a plurality of pilot holes 21, and they allow the inside of electric part box 9 and air-vent 13 to communicate with each other.Many pilot holes 21 are formed on the electric component C2 with big caloric value, near the part place for example converter circuitry.
Some electric component C1 and C2 can electrically be attached to dividing plate 20, or attachable and by dividing plate 20.Therefore, dividing plate 20 forms a space D who surrounds basically with respect to side plate 9a.
The inside of electric part box 9 by pilot hole 21 be formed between dividing plate 20 and the side plate 9a space D that surrounds basically and be communicated with.In addition, the inside of space D of Bao Weiing and cooling pipe 12 communicates with each other by air-vent 13 basically, and therefore, the inside of electric part box 9 is communicated with by the space D that surrounds basically with the inside of cooling pipe 12.
In such structure, the space D that surrounds basically that is formed by dividing plate 20 and side plate 9a inserts an air layer, this air layer like this, can obtain to shield the effect of heat from electric part box 9 inside to cooling pipe 12 between the inside and cooling pipe 12 of electric part box 9.
(the 3rd embodiment)
Next, with reference to Fig. 3 to 5 third embodiment of the present invention is described.Because the entire infrastructure of outdoor unit is identical with structure among above-mentioned Fig. 1 basically, therefore, utilizes and to omit extra description it to its diagram.Fig. 3 is the stereogram of the decomposition of electric part box 9, and Fig. 4 is the schematic section of the double structure member 30 of a formation electric part box 9 parts, and Fig. 5 is the stereogram of double structure member 30.
In Fig. 3, watch electric part box 9 from front face side, an air-vent 13 that is formed in the side plate 9a of electric part box 9 shown in the figure.Yet, omitted the cooling pipe 12 that is attached to the back side.Structure among above-mentioned Fig. 1 is applicable to the structure of cooling pipe 12 itself, and omits all descriptions.
