Abstract

The utility model is related to a kind of air-cooled filter of battery, mainly includes：Filter base 1, filter filter core 2, filter housing 3, installation fastener 4.For lithium ion battery for pure electric automobile, battery temperature in use scope is 20 DEG C 60 DEG C, if continuing big multiplying power discharging, and whole group battery proposes high requirement to radiating.Using the battery pack of air cooling way, if being directly sucked in natural wind, it will by dust, debris, mosquito etc. is brought into internal battery pack, causes battery pack potential safety hazard, short circuit can be caused when serious, causes major accident, so needing to carry out filtration treatment to suction air.

Description

The air-cooled filter of battery

Technical field

The utility model belongs to pure electric automobile cell safety applied technical field, and in particular to a kind of air-cooled filtering of battery Device.

Background technology

With the development of science and technology, non-renewable resources and automobile exhaust pollution problem become to become increasingly conspicuous, and this causes New-energy automobile increasingly causes the attention of society, and the direction that wherein pure electric automobile develops into future automobile.It is national big Power encourages pure electric automobile industry development, while preferentially supporting the development of electric motor coach correlation technique and the trial operation in various regions.

Battery is the core component of electric automobile, decides behaviour in service and the life-span of automobile, current batteries of electric automobile Use also there are many problems, the heat management of battery system is exactly one of them, in order to reduce influence of the heat to battery, mesh Preceding in the market is mainly radiated using air-cooled or water-cooled to battery, air-cooled to rely primarily on the wind produced in vehicle travel process Speed is cooled down or radiated with fan.

Battery is carried out it is air-cooled during, if containing a large amount of debris in the air of suction, mosquito, the foreign matter such as dust is just The service life of battery can be influenceed, or even causes short-circuit risks.So must be carried out to the cooling air for entering inside battery Filter, purified treatment.

Filter in the utility model, the air cooled down to battery is aerated the device of filtering, it is ensured that cooling The cleanliness factor of air, extends battery.

Utility model content

The purpose of this utility model is to carry out filtration treatment to its cooling air-flow using the battery pack of air cooling way, it is to avoid inhaled Enter impurity and influence cell safety to use.

The air-cooled filter of battery, including filter base 1, filter filter core 2, filter housing 3, installation are tightly Firmware 4, filter filter core 2 is installed on the bayonet socket of filter base 1, and filter filter core 2 is located at filter housing 3 Interior, filter device case 3 and filter base 1 are connected by installing fastener 4；Filter filter core 2 and filter bottom O-ring seal is embedded between seat 1, it is ensured that reliability and air-tightness that both assemble.

The air inlet of filter housing 3 sets air guide structure 5, and air guide structure 5 is provided with air inducing face 5-1 and choke face 5- What 2, air inducing face 5-1 realized air enters wind direction circumference traffic direction drainage；At the 5-2 of choke face, air flow wake flow is pressed into Filter core 2.

Fastened between filter housing 3 and filter base 1 by rounded cap nut 6.

The latch of filter housing 3 sets and prevents the filter caused by Long-term Vibration on filter base 1 The strip hole of osculum effect is opened on the rotational positioning groove around axial direction of housing, the latch of filter housing 3.

Filter housing 3 opens up rectangle air inlet, and air inlet sets injection filter screen, can stop that foreign matter enters air intake vent.

Filter filter core 2 uses pleated stainless steel filtering net, add clean air by area, reduce system wind Resistance.

The air inlet of filter housing 3 sets air guide structure, realizes that the wind direction circumference traffic direction that enters of air draws Stream.

The air-cooled filter of battery is arranged at outside electric automobile, and electric automobile is operated in can run into various differences among Operating mode, this requires to filter the cooling air of air intake electric automobile, and the air intake filter screen on filter housing is first Carry out coarse filtration, after refined filtration is carried out by filter core, on the one hand ensure by the clean level of air, on the other hand extend filtering dress The maintenance period put

Embodiment

Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.

As shown in figure 1, the air-cooled filter of battery, including filter base 1, filter filter core 2, filter shell Body 3, installation fastener 4, filter filter core 2 are installed on the bayonet socket of filter base 1, and filter filter core 2 was located at Filter in device case 3, filter device case 3 and filter base 1 are connected by installing fastener 4；Filter filter core 2 with O-ring seal is embedded between filter base 1, it is ensured that reliability and air-tightness that both assemble.

O-ring seal is embedded between filter core and base, it is ensured that reliability and air-tightness that both assemble.

As shown in Fig. 2 the latch of corresponding housing sets locating slot on filter base, it is therefore prevented that caused by Long-term Vibration Filter housing opens strip hole in axial rotation, enclosure latch, plays osculum.

As shown in figure 3, the cartridge support of filter base is fitted close with filter core inside groove, stud is installed and passes through filter core end Lid mounting hole, enclosure interior correspondence position sets support rim, and filter core and housing are locked at into installation by external nut fastening On base.

As shown in Figure 4 and Figure 5, air inlet sets air guide structure, and that realizes air enters wind direction circumference traffic direction drainage, The windage of whole system is reduced, in air inducing face, smooth raises shown in air-flow direction；In choke face, air flow wake flow It is pressed into filter core.

The air-cooled filter of battery of meter is proposed, the air inlet of battery case is connected by airduct.
