Description
Technical field
The invention belongs to electronlmobil field, particularly a kind of cooling method for arranging of onboard charger of electric car.
Background technology
Onboard charger, as electronlmobil vitals, to be arranged and cooling is crucial, and meeting that new forms of energy parts are arranged, under the prerequisite of performance requriements, how low cost, high reliability, less space hold are the primary problems solved.
The main at present type of cooling of onboard charger has that nature cools, force-air cooling and liquid cooling.
Naturally cold scheme is dispelled the heat by natural convection air, and structure is simple, but device temperature is high, comparatively large on all edge pieces impacts, position has limitation, can not be arranged in confined space, enough heat-dissipating spaces must be ensured, this and electric passenger vehicle space is generally compact disagrees.
Liquid cooling scheme advantage is that arrangement space demand is less, less on circumferential component impact; Shortcoming is that system is more complicated, and fluid circulation adds the complexity of system, brings the rising of cost and the reduction of reliability.
Force-air cooling increases the fan forcing cooling on naturally cold scheme basis, scheme cost between natural cold-peace liquid cooling, to the requirement of arrangement space also between above two schemes.
Limited for vehicle arrangement space, front deck arranges onboard charger without space, by studying arrangement, designing a kind of force-air cooling onboard charger and being arranged in the confined space of former car spare tyre pond, meet low cost, the cooling arrangement requirement of high reliability.
At present, in known technology, have with the akin technologic material of the technology of the present invention effect:
CN200610157108.7, it discloses a kind of cooling mechanism and method of onboard charger of electric car.
The advantage of this technology is: this onboard charger of electric car connects exhaust passage and ft connection by the air inlet duct in car through onboard charger, is achieved the force-air cooling cooling of onboard charger by the fan in air channel.
This technology shortcoming be:
1. this onboard charger heat sink conception needs air inlet duct and exhaust passage, and the outer arrangement space of occupying volume, increases cost of development;
2. this onboard charger fan is arranged in air channel, causes air channel volume to become large, and the outer arrangement space of occupying volume, increases cost of development;
3. this onboard charger heat sink conception needs onboard charger to be communicated with body exterior by air channel, and using former car breather port to exist affect vehicle closure power risk, outputs air channel connecting bore for this reason there is vehicle and to leak risk as special.
Summary of the invention
The object of the invention is: in order to overcome electronlmobil spaces compact, the present situation of arrangement space deficiency, and provide a kind of novel electric vehicle force-air cooling onboard charger to arrange and cooling scheme, this conceptual design is applicable to spaces compact, onboard charger is arranged without sufficient space in front deck and other places, cancel spare tyre in former car spare tyre pond and increase instruments such as joining tyre repairing fluid, additionally do not take boot space situation.
Concrete technical scheme is as follows:
A kind of onboard charger of electric car, is characterized in that described onboard charger is fixed in spare tyre pond.
Between described spare tyre pond and described onboard charger, fill support component, and leave space between support component and spare tyre pond.
Described space is the flowable cooling loop of air-flow formed between support component and spare tyre pond.
Described cooling loop is the closed-loop of air-flow counterclockwise flow.
Described support component is foam support block.
The moving direction of described air-flow in cooling loop is onboard charger ventilation inlet, onboard charger inside, onboard charger air outlet, rear end panel, spare tyre pond right sidewall, sidewall, charger air inlet spare tyre pond sidewall on front side of spare tyre pond, get back to onboard charger ventilation inlet.
Described onboard charger comprises the fan inside independently controlled by described onboard charger.
Space below described support component can be used for placing driver's tool, the car load parts that charging wire or other needs are arranged, and support component and cooling loop are kept apart, and do not affect wind circulation.
A kind of cooling method of onboard charger of electric car, it is characterized in that the temperature information of the temperature sensor collection that described onboard charger is arranged according to the power device of therein passes to the internal piloting unit of described onboard charger, control the rotating speed of described fan inside, thus the speed that control air flows in described closed-loop.
On front side of described spare tyre pond, sidewall is sheet metal structural, and circulating air and described sheet metal structural carry out interchange of heat, and described sheet metal structural, by metal conduction, carries out interchange of heat with vehicle outside air, finally completes the interchange of heat of onboard charger and outside vehicle.
Compared with currently available technology, the present invention has the following advantages:
1. onboard charger is arranged in the confined space of vehicle spare tyre pond, without the need to the wind inlet channel that externally connects and exhaust air flue, solves external air channel taking space, effectively reduces cost of development simultaneously;
2. onboard charger integrated heat dissipation fan, solves provided with fan additionally taking space in external air channel;
3. inner air circulates the object realizing being reached cooling by the spare tyre pond external interchange of heat of integrated sheet-metal along spare tyre Chi Banjinbi, realizes the cooling of onboard charger when sealing;
4. need not vehicle body to the duct outlet of exterior open cell, reduce cost of development, evade the risk of leaking that perforate brings.
So scheme is under the prerequisite meeting electric vehicle development demand, bring significant performance boost and huge economic benefit.
