And this chamber 8a is a negative pressure, send cold wind facing to radiator 20, can obtain sufficient radiating effect.And, because along the prominent cooling fins 20a that establishes of the whole width of radiator 20 ... be in radial expansion, the air output that flows through between fin increases, and can obtain more sufficient radiating effect.
Derive by the hot-air of spare parts kit body 16 inside of electric controling part S liberated heat heating from the joint-cutting 39 of the casing side surface part 18b that is positioned at this chamber 8a, thereby stoped the unusual rising of internal temperature.
Because in the prominent pushing portion 38 that establishing of the opening direction of this joint-cutting 39, this pushing portion 38 is configured under the intrinsic state of unit pushing tow in front on the plate 3 at electric part box 15, therefore, stoped in the chamber 8a of casing side surface part 18b side and the connection of 8b, thereby prevented that air from flowing into joint-cutting 19 peristomes.
The hot-air of spare parts kit body 16 inside also flows out from outstanding flow export 27 places of casing lower face 18a.Blocked the intrusion of water droplet or dust by being contained in baffle plate 28 on flow export 27 peristomes, they can not stick on the inner electric controling part S, thereby have improved reliability.
From the 2 row joint- cuttings 46,47 that are arranged on the casing lower face 18a tempering air is imported spare parts kit body 16 inside, cooling electric control assembly S prevents that temperature from raising.
These joint- cuttings 46,47 are facing to SL joint installing plate 42 openings, and in other words, SL joint installing plate 42 is positioned at the cooling air and imports side.And this installing plate 42 is crooked by joint-cutting 46,47 to oblique below, has prevented to have had water-proof function in the water droplet intrusion spare parts kit body 16.
Especially, the 29 pairs of tempering airs that import spare parts kit bodies 16 inside from above-mentioned joint-cutting 46,47 of the rectifier that having the enhancing function concurrently that are arranged on the mounting support body 17 carry out rectification, and guiding electric controling part S, further improve cooling effectiveness.
Therefore, electric part box 15 bridges on chamber 8a and 8b, to cool off in the air importing case from the joint-cutting 46,47 and the opening 50 of chamber 8b side, through rectification part 29 rectifications, these air are flowed out from the flow export 27 and the joint-cutting 39 of chamber 8a side, therefore, with the electric controling part S of control on the substrate P towards forming the following of case inner air flow road, can make more effectively cooling electric control assembly S of the cooling air that flows through in the case to combining.
Since be installed on lid 19 and control between the substrate P insulation board 52 and the control substrate P between the strong material plate 55 that prevents tracking is installed, so even insulation board 52 contacts with controlling substrate P, also can be high voltage withstanding.
Hold the control substrate P that electric controling part S is installed in the above-mentioned insulation board 52, and keep holding state ground, can be integral with the control substrate P with resin-sealed.Under this state, because of supporting part is all sealed with resin with respect to the control substrate P of electric controling part S.So constituted the salt tolerant structure.
As above said, because whole electric controling parts are installed on the control substrate, and be contained in the spare parts kit with facing down, so it is comparatively simple that distribution is handled, the assembling operation of electric part box and maintenance property are better, simultaneously because all electric controling part is below formation case inner air flow road, so can set complicated air flow path, needn't much cool off and use opening, can improve cooling effect.
Because the structure that radiator has adopted anti-heat to run off, so can improve the cooling effectiveness of the king-sized electric controling part of cooling caloric value.
Because spare parts kit is the dual structure of the mounting support body and the metallic plate casing of resin injection molded material,, when reliably protecting is contained in inner electric part box and control substrate, realize erasure effect so can guarantee the rigidity of spare parts kit body.
The mounting support body has certain retentive control substrate, the effect of the cooling effectiveness of reduction stress and raising cooling electric control assembly and the processing of simplification distribution etc.
Casing is except the rigidity of guaranteeing the spare parts kit body, and also cooling electric control assembly more effectively can prevent simultaneously the intrusion of water droplet or dust, improves reliability.
Because lid is installed on the control substrate dismantledly, so available lid covers the control substrate, protection control substrate.
Owing between lid and control substrate, insulation board is installed, therefore can make the control substrate anti-, realize electric insulation, and have withstand voltage effect.
Because substrate will be controlled and insulation board is sealed, just can improve the salt resistant character of controlling substrate with resin.
