Enclose shell 52 mode be provided with directing plate embodiment schematic diagram.As shown in fig. 7, in the housing H of heat exchanger body
Top plate TP form opening portion h, in opening portion, h sets funnelform directing plate 56.Directing plate 56 is to surround converter unit IVU's
The mode of shell 52 configures.Directing plate 56 is made up of cylindrical portion 56a, inverted cone-shaped portion 56b and tube 56c, tube
56c bottom is connected with top plate TP opening portion h.Converter unit IVU is supported by the supporting member 56s extended from directing plate 56.
Composition according to Fig. 7, it can utilize by the negative pressure formed by fan assembly 3 and hot friendship is inhaled into by opening portion h
The flowing of air in exchanger body, converter unit IVU is cooled down.The flowing of above-mentioned air is formed at directing plate 56 with becoming
Path between frequency unit IVU shell 52, and the path being formed between adjacent fin 52f, therefore can utilize
The flowing of the air of converter unit IVU side, further converter unit IVU is cooled down.In addition in the figure 7, although
Top plate TP is provided with directing plate 56, but can also set directing plate 56 in side plate SP.
In the embodiment shown in Fig. 6 (a), Fig. 6 (b), Fig. 6 (c) and Fig. 7, including converter unit IVU power
When frequency converter 8 including element 50 operates, fan assembly 3 operates and rotates fan 5, therefore turns into heat exchanger body negative
Pressure.Formed by the negative pressure by being formed at housing H opening portion h the flowing of air that is drawn into heat exchanger body.
That is, the negative pressure in the heat exchanger body formed by fan assembly 3 can be utilized, around converter unit IVU shell 52
Form the flowing of air.Therefore with fan or it is provided with converter unit IVU control panel without using the air-cooled of converter unit IVU
It is air-cooled to use fan, it becomes possible to which that converter unit IVU is cooled down.Converter unit IVU is installed on shell by opening portion H-shaped Cheng Yu
Near body H installation portion or the installation portion.Converter unit IVU can be directly mounted at opening portion h by page, can also be via pipe
Installed in road 55 etc..
In addition, as described above, converter unit IVU power cable hole 52a and cable hole 52b using seal member and
As the unapproachable airtight construction of extraneous air, therefore can prevent with being drawn into because of negative pressure in heat exchanger body
Moisture entrained by the flowing of air enters converter unit IVU shell.
Above-mentioned embodiment can implement this practicality newly with the people of the general knowledge with the utility model art
Recorded for the purpose of type.As long as those skilled in the art, then it can implement the various modifications of above-mentioned embodiment certainly
Example, technological thought of the present utility model can also be applied to other embodiment.Therefore the utility model is not limited to described
Embodiment, and should be regarded as the widest scope according to technological thought as defined in the claims.
