Therefore, people have proposed the technology of following reduction generation from the noise of reactor.
For example, among the Japanese kokai publication hei 08-111322 a kind of noise reduction technology is disclosed.In this noise reduction technology, have greater than 100kgf/cm with one
2The adhesive of adhesion strength carry out between core body (iron core) the member contact portion bonding, by stacked fixing with between a bonding and fixing and coil between the steel plate of making core member and the core body of painting.
In addition, in the special fair 03-66805 of Japan Patent, disclose and a kind ofly held the technology that prevents noise on the housing of reactor by a reinforcement stay or a stacked vibration damping steel plate being connected one.
Yet, owing to produce from the noise that is used for the reactor on fuel cell-powered car or the motor vehicle driven by mixed power well beyond the noise level of the general consumer goods, thus only by as described in the Japanese kokai publication hei 08-111322 with between the adhesive reinforcement core member contact portion, between the stacked steel plate of core body and the structural measure the bonding force between core body and the coil can not be reduced to noise the noise level of requirement.
In the disclosed structure of the special fair 03-66805 of Japan Patent, this housing itself is very big, and is connected on this housing strengthening stay and stacked vibration damping steel plate, so this reactor has increased on the whole.So this reactor is not suitable for vehicle-mounted (on-vehicle) device, and structurally is difficult to a large amount of productions.
Summary of the invention
The invention provides the noise-reduction method and the device that are used for a reactor, a noise that is used for the reactor of a fuel cell-powered car or a motor vehicle driven by mixed power has obtained effective control thus, and this device is miniaturized and has improved mass productivity.

Therefore, owing to can close the peristome of this housing-reduce noise, by a simple structure-the use cap seal of making by foamed material with semicontinuous semi-independent balloon-shaped structure so can produce denoising device in batches with low cost.
In addition, (size) do not increase because reactor, do not destroy the demand of vehicle-mounted reactor miniaturization so can carry out noise control.
Aspect above-mentioned, preferably described foamed material is arranged on a compressive state in the peristome of housing of described high thermal conductivity.
Therefore, this lid stretches with the gap between closure casing and the lid perpendicular to the compression direction of foamed material, and closely connects (adhesion) on the surface of sealing resin.
Thus, can prevent noise by the clearance leakage between this housing and the lid to carry out noise control effectively.
Therefore, according to the present invention, can produce denoising device in batches with low cost thereby can reduce noise by a simple structure.
In addition, can carry out noise control effectively and not destroy the demand of vehicle-mounted reactor miniaturization.

Fig. 2 is the end view of this denoising device;
Fig. 3 is the front view of this denoising device;

Embodiment
Next, with reference to the accompanying drawings embodiments of the invention are described.
According to the denoising device that is used for a reactor of first embodiment of the invention as shown in Figures 1 to 3.
This denoising device 1 comprises the sealing resin 8 that a housing 2, that holds this reactor that comprises a core body 5 and a coil 6 is filled the inner space of housing 2, and the lid 7 of a peristome 2a of this housing 2 of sealing.
This housing 2 be an opening make progress box-like, and be installed on the heat dump 9.
By this reactor of housing 2 holds and comprises core body 5 and coil 6 in the one side by a spring 3 bias voltages, so that it is positioned to contact with a side surface of housing 2.
Sealing resin 8 is made of epoxy resin, polyurethane resin etc.Make the inner space of sealing resin 8 by cast modes such as (potting), sealing resin 8 is solidified with pasty state its uncured state filling housing 2.Except a terminal 6a of coil 6, core body 5 and coil 6 complete sealed resins 8 cover.
In addition, lid 7 be arranged in the peristome 2a of housing 2 so as to contact with the top surface of sealing resin 8 or and this top surface between a minim gap is arranged, thereby seal this peristome 2a.
Foamed material with semicontinuous semi-independent balloon-shaped structure is defined as the foamed material that a wherein perforate (continuous air bubbles) and closed pore (separated foam) mix mutually.For example, in the present embodiment, (in this material) has only about half of perforate and the closed pore that respectively accounts for whole bubbles.
In the present embodiment, for example, use an adhesive, adhesive tape etc. thickness to be fixed to the top surface of sealing resin 8 as 10mm or bigger lid 7.
Therefore, housing 2 with high thermal conductivity holds the reactor that comprises coil 6 and core body 5, and fill the inner space of housings 2 with sealing resin 8, sealing resin 8 is solidified, use the peristome 2a of lid 7 closure casings of making by foamed material 2 subsequently, constituted denoising device 1 thus with semicontinuous semi-independent balloon-shaped structure.
Because the reactor that is used for fuel cell-powered car or motor vehicle driven by mixed power is with high electric current and driven,, make this reactor formation vibration and noise bigger and more violent than the general consumer goods so the gravitation that is produced by pulsating current is also very big.
When the housing 2 that is combined with core body 5 and coil 6 is filled with sealing resin 8 simply, generation in the vibration of reactor, have about 5kHz or more the vibration along continuous straight runs of small frequency transmit by sealing resin 8, thereby make the side surface vibration of housing 2 and form noise.
When the vibration with about 10kHz frequency is advanced, come back reflective between the member that comprises core body 5 and coil 6 that it holds in housing 2 and housing 2 in sealing resin 8, and leak out from the peristome 2a of housing 2 and become noise.
The lid of being made by the foamed material with semicontinuous semi-independent balloon-shaped structure 7 has reflection and absorbs the function of the noise that leaks out from the peristome 2a of housing 2.Therefore, reflection of the lid 7 of the peristome 2a of closure casing 2 and the vibration that absorbs frequency and leak out from the peristome 2a of housing 2 with about 10kHz.The interreflection and the absorption of 7 pairs of vibrations of lid have reduced noise.
Because the common running frequency of a vehicle-mounted inverter is about 10kHz, so can reduce noise on the whole by reducing the lid 7 that produces from the noise of housing 2 peristome 2a from reactor.
Therefore, owing to can have the peristome 2a of lid 7 closure casings 2 that the foamed material of semicontinuous semi-independent balloon-shaped structure makes-reduce noise, by a simple structure-usefulness so can low cost batch process denoising device.In addition, (size) do not increase because reactor, so can carry out noise control and don't destroy the demand of vehicle-mounted reactor miniaturization.
Next, will describe the second embodiment of the present invention.In second embodiment of this denoising device 1, also be connected with a cover 10 on the peristome 2a of housing 2, this denoising device 1 that is used for reactor is as shown in Figure 4.Therefore, cover 10 also is covered with in the peristome 2a that is arranged on housing 2 to seal the lid 7 of this peristome 2a.
