Description
Technical field
The invention belongs to electric automobile field, the cooling method for arranging of particularly a kind of onboard charger of electric car.
Background technology
For onboard charger as one important component of electric automobile, arrangement and cooling are crucial, are meeting new energy zero
Part arrangement, on the premise of performance requirement, how low cost, high reliability, less space hold are that primarily solve the problems, such as.
The onboard charger type of cooling main at present has natural cooling, air blast cooling and liquid cold.
Naturally cold scheme is radiated by natural convection air, simple in construction, but device temperature is high, periphery member is influenceed compared with
Greatly, position has limitation, it is impossible to is arranged in confined space, it is necessary to ensure enough heat-dissipating spaces, this with it is electronic
Passenger car space is generally compact to disagree.
The cold scheme advantage of liquid is that arrangement space demand is smaller, circumferential component is influenceed smaller；Shortcoming is that system is more complicated, liquid
The circulatory system adds the complexity of system, brings the rising of cost and the reduction of reliability.
Air blast cooling increases the fan for forcing cooling on the basis of naturally cold scheme, and scheme cost is cold between naturally cold and liquid
Between, the requirement to arrangement space is also between two above scheme.
Limited for vehicle arrangement space, front deck arranges onboard charger without space, by being ground to arrangement
Study carefully, design a kind of air blast cooling onboard charger and be arranged in former car spare tyre pond confined space, meet low cost, high reliability
Cool down arrangement requirement.
At present, in known technology, the technologic material close with the technology of the present invention effect has：
CN200610157108.7, it discloses a kind of cooling device of onboard charger of electric car and method.
The advantages of technology is：The onboard charger of electric car is connected by the air inlet duct of in-car by onboard charger
Exhaust passage and ft connection, the air blast cooling that onboard charger is realized by the fan in air channel cool down.
The technology the shortcomings that be：
1. the onboard charger heat sink conception needs air inlet duct and exhaust passage, extra arrangement space, increase exploitation are taken
Cost；
2. the onboard charger fan is arranged in air channel, causes air channel volume to become big, take extra arrangement space, increase
Development cost；
3. the onboard charger heat sink conception needs onboard charger to be connected by air channel with body exterior, led to using former car
There is influence vehicle closure power risk in air holes, such as output air channel connecting hole exclusively for this and vehicle leak risk be present.
The content of the invention
The purpose of the present invention is：In order to overcome electric automobile spaces compact, the present situation of arrangement space deficiency, and provide a kind of
Novel electric vehicle air blast cooling onboard charger is arranged and cooling scheme, this conceptual design are applied to spaces compact, front deck with
Onboard charger is arranged without sufficient space elsewhere, cancels spare tyre in former car spare tyre pond and increases with instruments such as tyre repairing fluids, not volume
The outer situation for taking boot space.
Concrete technical scheme is as follows：
A kind of onboard charger of electric car, it is characterised in that the onboard charger is fixed in spare tyre pond.
Support member is filled between the spare tyre pond and the onboard charger, and is stayed between support member and spare tyre pond
There is space.
The flowable cooling circuit of air-flow that the space is formed between support member and spare tyre pond.
The cooling circuit is the closed-loop of air-flow counterclockwise flow.
The support member is foam support block.
Moving direction of the air-flow in cooling circuit be onboard charger air inlet, inside onboard charger, it is vehicle-mounted
Charger air outlet, squab panel, spare tyre pond right sidewall, spare tyre pond front side sidewall, charger air inlet spare tyre pond side wall, return
To onboard charger air inlet.
The onboard charger includes the internal fan by the onboard charger independent control.
Space below the support member can be used for placing driver's tool, the vehicle that charging wire or other needs are arranged
Part, and support member is kept apart with cooling circuit, does not influence air circulation.
A kind of cooling means of onboard charger of electric car, it is characterised in that the onboard charger is according to therein
The temperature information of temperature sensor collection of power device arrangement be transmitted to the internal control unit of the onboard charger, control
The rotating speed of the internal fan, so as to control the speed that air flows in the closed-loop.
Spare tyre pond front side sidewall is sheet metal structural, and circulation air carries out heat exchange, the metal plate with the sheet metal structural
Golden structure carries out heat exchange with vehicle outside air, is finally completed the heat of onboard charger and outside vehicle by metal conduction
Exchange.
Compared with currently available technology, the present invention has advantages below：
1. onboard charger is arranged in the confined space of vehicle spare tyre pond, wind inlet channel and air-out wind without external connection
Road, solve occupancy of the external air channel to space, while effectively reduce development cost；
2. onboard charger integrated heat dissipation fan, solve that extra occupancy of the fan to space is installed in external air channel；
Reached 3. inner air circulates realization along spare tyre Chi Banjinbi by the external heat exchange of integrated sheet-metal of spare tyre pond
The purpose of cooling, the cooling of onboard charger is realized in the case of sealing；
4. without duct outlet of the vehicle body to exterior open cell is needed, development cost is reduced, evades the leak risk that perforate band is come.
So scheme on the premise of electric vehicle development demand is met, brings significant performance boost and huge warp
Ji benefit.
