[background technology]
Electric motor coach is as a kind of free of contamination green traffic instrument, energy-conserving and environment-protective, and prospect of the application is very good.Because the heating when work of the power battery pack on the electric motor coach, temperature rise are very fast, need to effectively dispel the heat, lower the temperature battery pack for making the electrokinetic cell normal operation, common cooling system is divided into compulsory air-cooled and two kinds of water-cooleds.Wherein the wind-cooling heat dissipating system powers with power battery pack, with electronic fan battery pack is done blowing or exhausting cooling, use electronic fan can increase battery operated load, improve operation cost, also can shorten the average daily distance travelled 3～6KM of electric motor car, long-term use more needs maintenance cost, take the power battery pack that is divided into 4 or 8 power brick as example, each power brick adopts 3 24W electronic fans, need additional 12 or 24 electronic fans, the power battery pack required fan gross power of dispelling the heat is 288W or 576W, and electric motor coach calculated by average daily operation running time in 10 hours, power consumption every day 2.88 or 5.76 degree will shorten the average daily distance travelled 3～6KM of electric motor car.Water-cooling heat radiating system will be embedded water channel in each module on power battery pack, one cover Electronic Control water-circulating pump is installed, heat by water circuit fluxion strap walking power battery pack work generation, because power battery pack often is comprised of 20 to 22 modules and mostly mutually put down folded, the cooling water pipe access structure of installing and using is complicated, elbow is many, cause the current damping in the pipeline larger, flow velocity is slow, high to the pump motor performance requirement, the pump motor of 250W direct current or other form is installed as example take 10 hours motor vehicle of an average daily job, about 2.5 degree of the required day power consumption of dispelling the heat, use cost is high, less economical, long-term use also needs maintenance cost, and there is the accidents caused potential safety hazard of leaking all the time in the water channel battery module of flowing through.
[summary of the invention]
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome the technological deficiency that has air-cooled and two kinds of cooling systems of water-cooled now, provide a kind of simple in structure, use safety, heat radiating system for battery pack that cost is low, described cooling system carries out radiating and cooling by Compressed Gas to power battery pack, need not to install electronic fan or is embedded water channel, pump motor.
The technical scheme that technical solution problem of the present invention adopts: heat radiating system for battery pack, comprise that Compressed Gas is for source and gas pipeline, the input of gas pipeline connects Compressed Gas for the source, output connects the battery case of laying battery, it is characterized in that described Compressed Gas comprises the exhaust of passenger vehicle main brake valve for the source, be connected to gas pipeline on the passenger vehicle main brake valve and connect battery case.The present invention utilizes meeting absorption of gases ambient heat when Compressed Gas is anxious to gather expansion, has the operation principle of obvious refrigeration, collects Compressed Gas and delivers to battery case as coolant, and the battery pack of the heating of working in the battery case is dispelled the heat, cooled.Because electric motor coach is adopting the gas braking in running, during frequent Brake stop, brake rim on the electric motor coach can continuously outwards discharge a large amount of compression brake gases by the passenger vehicle main brake valve, collect the brake gas that the passenger vehicle main brake valve is discharged by gas pipeline, power battery pack on the electric motor coach is dispelled the heat, cooled off, the original directly waste gas of discharging is used environmental protection and energy saving.
On the gas pipeline of the connection passenger vehicle main brake valve described in the present invention unidirectional valve is housed.The effect of unidirectional valve is to avoid the brake gas adverse current, guarantees that the unidirectional conveying of brake gas dispels the heat to power battery pack, helps to strengthen radiating effect.
Heat radiating system for battery pack, comprise that Compressed Gas is for source and gas pipeline, the input of gas pipeline connects Compressed Gas for the source, output connects the battery case of laying battery, it is characterized in that described Compressed Gas comprises the total valve exhaust of passenger vehicle Electronic Control Air Suspension System for the source, be connected to gas pipeline on the passenger vehicle Electronic Control Air Suspension System main valve and connect battery case.The Electronic Control Air Suspension System that is called for short the ECAS system is common on high-grade bus and the touring car, realize automatic lifting and the inclination of car load height by control air bag inflation/deflation, get on or off the bus with convenient handicapped person, also can discharge Compressed Gas by corresponding Electronic Control Air Suspension System main valve (ECAS system main valve) during this system works, the Compressed Gas that the present invention arranges the discharge of gas pipeline collection passenger vehicle Electronic Control Air Suspension System main valve dispels the heat, cools off power battery pack, effectively utilize waste gas, environmental protection and energy saving.
On the gas pipeline of the connection passenger vehicle Electronic Control Air Suspension System main valve described in the present invention unidirectional valve is housed.The effect of unidirectional valve is the Compressed Gas adverse current of avoiding passenger vehicle Electronic Control Air Suspension System main valve to discharge, guarantees the unidirectional conveying heat-radiation dynamic cell of Compressed Gas group, helps to strengthen radiating effect.
Heat radiating system for battery pack, comprise that Compressed Gas is for source and gas pipeline, the input of gas pipeline connects Compressed Gas for the source, output connects the battery case of laying battery, it is characterized in that described Compressed Gas comprises the exhaust of passenger vehicle main brake valve and the total valve exhaust of passenger vehicle Electronic Control Air Suspension System for the source, the passenger vehicle main brake valve is connected with passenger vehicle Electronic Control Air Suspension System main valve and all is connected to gas pipeline and connects battery case, connects respectively on the gas pipeline of two main valves unidirectional valve all is housed.The exhaust of passenger vehicle main brake valve and two sources of the gas of the total valve exhaust of passenger vehicle Electronic Control Air Suspension System are combined, take full advantage of institute's waste air, air feed is more sufficient, and is better to the radiating effect of power battery pack for the source than single compressed gas; Two unidirectional valves are used for guaranteeing the unidirectional conveying of Compressed Gas of each self-discharging, improve radiating effect.
Compressed Gas described in the present invention comprises the gas receiver air feed for the source, is connected to gas pipeline on the gas receiver and connects battery case, and unidirectional electric control solenoid valve is housed on the described gas pipeline.Utilize the work Compressed Gas in the gas receiver that power battery pack is dispelled the heat, cooled off, satisfy the power battery pack needs that dispel the heat normally; The unidirectional electric control solenoid valve of ripple control is used for the gas transmission state of control gas receiver.
