On the other hand; As shown in Figure 5; Substantial middle portion in shell 31 inside; Whole vertically (highly) direction from top to bottom is formed with the indoor two-part dividing plate 41 in the left and right sides that is divided into, and with about indoor (left side among Fig. 5 is indoor) of a side in two Room be divided into up and down that two-part mode is set with stand 42 at dividing plate 41, this stand 42 is provided with shelf 42A in the vertical substantial middle portion of (highly) direction.This shelf 42A and the stand 42 that is provided with this shelf 42A are formed by appropriate insulation property material.Through said structure, be formed with the A of fan room, Machine Room B, Denso chamber C in the inside of shell 31.
Shown in Fig. 5 (A), be provided with fluid reservoir 7 at the A of fan room, and be provided with condenser 6 and cool off the fan F of this condenser 6.On the other hand, B is provided with accumulator 3, compressor 4, not shown screen pack, Filter dryer and decompressor etc. in the Machine Room.The C in the Denso chamber; Though various parts of electric such as filter circuit 12, substrate 13, converter 11 carry on stand 42, especially that caloric value is many converters 11 be configured in the downstream of flowing as extraneous air from extraneous air inlet hole 35B suction in portion.In addition, at this stand 42 to carry not shown control circuit near not shown front plate 32 range upon range of modes, utilize hinge that not shown plywood is installed at dividing plate 41.
Dividing plate 41 is integrally formed to extend the mode that is provided with from support plate 43, near this support plate 43 is fixedly set in this edge of opening along the edge of opening portion of the air entry 35A of backplate 35.In addition, utilize dividing plate 41, after the extraneous air that sucks from extraneous air inlet hole 35B flow through Denso chamber C, C flowed out to the A of fan room this extraneous air from the Denso chamber.In addition, be provided with rainproof exhaust portion 50 at dividing plate 41.
On the other hand; Because support plate 43 is as being used to prevent that the splash guard from the rainwater that the mesh members 36 of the air entry 35A that is arranged at backplate 35 gets into is invaded Machine Room B and Denso chamber C from working, so preferably form by the material with insulating properties and water proofing property etc.Need to prove; In this embodiment; Though use a plate to have water-proof function; But for example, also can constitute, thereby B is inner towards the Machine Room flows into for the extraneous air that also can make the air entry 35A that comes from backplate 35 by porous plates such as punch metal plate with gas permeability or metal laths.
Then, the effect to this embodiment describes.
In this embodiment; For being in for the accumulator 3 of the low-temperature condition of outside air temperature; At the backplate 35 of the shell 31 of off-premises station shown in Figure 4 30, particularly in the zone right, in other words with the surface of position that accumulator 3 is set; Being equivalent in Machine Room B shown in Figure 5, left the corner portions located of the backplate 35 of the F of fan room part farthest, offers to suck extraneous air to carry out air cooled extraneous air inlet hole 35B.
Therefore; When these shell 31 inside of the inflow of the extraneous air after extraneous air inlet hole 35B is drawn into shell 31 inside just, at first, this extraneous air is by accumulator 3 coolings; Flow through Machine Room B, Denso chamber C afterwards in shell 31 inside successively, discharge from the A of fan room at last.
That is after flowing through Machine Room B, the inner extraneous airs of shell 31 that, are drawn into off-premises station 30 flow into the Denso chamber that is equipped with the many parts of electric of caloric value.Therefore, even for example in summer etc. the time, become easily under the situation that the other countries such as Thailand, Indonesia, Vietnam or torrid areas in the area, particularly Southeast Asia of high temperature use, refrigerating plant also can turn round continuously.Even under the situation of (reaching for example about the 43 ℃) extraneous air that sucks the high temperature that for example surpasses 40 ℃ from extraneous air inlet hole 35B, this extraneous air also at first is blown into and is arranged at the nearest accumulator 3 from extraneous air inlet hole 35B.Thus; Owing to make the temperature of extraneous air significantly cool off the uses such as air of back through extraneous air being flow through be in, so can cool off parts of electric effectively as the various parts of electric of cooling well below the near surface of the low-temperature condition of outside air temperature accumulator 3 down.
Therefore, even under the situation of using the general converter that does not possess one-piece type radiator, the converter 11 that is in the condition of high temperature is cooled to for example is no more than 60 ℃.Thus, because the ground work of converter 11 all-the-time stable, so, refrigerating plant is turned round continuously even in for example Southeast Asia or be under the situation that the countries such as torrid areas under the equator are provided with off-premises station 30 without.And, in the C of Denso chamber, because the converter 11 that caloric value is maximum in the parts of electric is so that extraneous air flows through the mode of this converter 11 at last is disposed in the C of Denso chamber, so can bring into play air cooled effect effectively.Therefore, a kind of off-premises station 30 can be provided,, also can obtain effective thermolysis at an easy rate, and can not cause shell 31 to maximize even special-purpose cooling mechanism is not set at converter 11.
Thus; According to this embodiment; In Fig. 5; From the extraneous air that the extraneous air inlet hole 35B in the zone of facing with accumulator 3 that is opened in Machine Room B backplate 35 behind sucks, after being cooled when flowing through near the container outer surface of accumulator 3, extraneous air is from flowing into Denso chamber C as the clearance D between the side wall surface 31C of the shelf 42A of the stand on the border of Machine Room B and Denso chamber C and shell 31 1 sides.
Then, after this extraneous air flow through Denso chamber C, C flowed out to the A of fan room from the Denso chamber to pass through the rainproof exhaust portion 50 that is arranged at dividing plate 41.In other words, constitute following structure: extraneous air flow through at first be arranged at Machine Room B refrigerating plant with the accumulator that is in the lowest temperature state in the parts 3, and extraneous air flows through at last, and to produce the maximum parts of electric of Joule heat be converter 11.Therefore, a kind of off-premises station 30 can be provided,, also can obtain effective thermolysis at an easy rate, and can not cause shell 31 to maximize even special-purpose cooling mechanism or heat abstractor etc. are not set.
And in this embodiment, rainproof exhaust portion 50 is arranged at the part of the open pore 41A that offers at the wall of the A of the fan room side that faces Denso chamber C of dividing plate 41, and the casing 51 of this rainproof exhaust portion 50 is formed by the general hollow casing (antidrip water tank) of thin thickness.Have the inlet 52 that is provided with and sucks extraneous air with the mode that is communicated with the open pore 41A of dividing plate 41 in the side of these casing 51 1 sides, in addition, have the outlet 53 that extraneous air is discharged to the A of fan room in the bottom surface of casing 51.Therefore; Because the opening portion of the rainproof exhaust portion 50 in the A of fan room, that is, the inflow entrance that comes from the air of Denso chamber C also only is formed at the downside of casing 51 in the A of fan room; So under weather conditions such as big rainy day; Even rainwater gets in the A of fan room in a large number, therefore this rainproof exhaust portion 50 can prevent that also as working at the dark eaves of above-below direction this rainwater from getting in the Denso chamber C.Thus, can avoid the parts of electric in the C of Denso chamber to produce short circuit etc., and can realize safety and the high off-premises station 30 of reliability, and then can realize safety and the high refrigerating plant of reliability.
And; Usually be difficult to use the subsidiary integratedly special-purpose converter that is provided with radiator that uses in Japan because source power supply voltage is high in the past; Therefore; Manufacturing for example is provided with the heat radiator dedicated converter with high universalizable of this voltage of reply etc. integratedly especially, still possibly produce the cost increase in this case, need spend the problem that the more time be used to make above-mentioned converter.
But; Off-premises station 30 according to this embodiment; Only, just can realize effective air cooler environment, even therefore off-premises station 30 is set in the high temperature area in the inside of shell 31 through changing each built-in configuration of components; Even use general converter 11, converter 11 is worked reliably.Consequently, do not expend cost and over head time, even and at source power supply than under the high high pressure in Japan and in the high temperature area etc., refrigerating plant is turned round continuously, very convenient.
Need to prove that the present invention is not limited to above-mentioned embodiment, in the scope that does not break away from the purport that each side invention put down in writing, can carry out various distortion.
For example; In this embodiment; Though use the plate that has gas permeability and the hole is not set that formed by the material with insulating properties and water proofing property to be fixedly arranged near the support plate 43 this edge of opening portion as the edge of opening portion along the air entry 35A of backplate 34, the present invention also can use porous plates such as punch metal plate or metal lath.That is, can be in the Denso chamber back side of the stand with insulating properties 42 of C and the behind of Machine Room B, in the face of this rear side and behind, the support plate 43 that is made up of the porous plate with gas permeability is set.Through constituting said structure, for the part of extraneous air that the air entry 35A from shell 31 is drawn into the A of fan room, also be formed with the path that flows to the wind of Machine Room B from support plate 43.Therefore, correspondingly can further improve cooling effect with said structure.
Need to prove; Under the situation that constitutes said structure; Part in the extraneous air that is drawn into the A of fan room is from the inflow destination of support plate 43 inflows; State to surround Denso chamber C is provided with the stand 42 with insulating properties, so the extraneous air that can avoid being drawn into the A of fan room flows into Denso chamber C from support plate 43.Therefore, under weather such as rainy day, also can utilize stand 42 to prevent that rainwater from flowing into Denso chamber C with the extraneous air that is drawn into the A of fan room, and also can prevent to produce peril such as electric leakage.
