Description

A kind of temperature regulating system
Technical field
The utility model relates to battery pack, particularly a kind of power battery pack humidity control system used on hybrid electric bus.
Background technology
Hybrid electric bus is as a kind of product of energy-conserving and environment-protective, and prospect of the application is very good.Power battery pack due to hybrid electric bus needs to drive vehicle separately in some cases, therefore demanded power output is very high, and the capacity relative pure electric automobile of battery pack is smaller, again because the power difference of battery in use charging and discharging is not very large, therefore the charge-discharge magnification of power battery pack is all very high.The power battery pack of so relative low capacity is in powerful charge and discharge process, and heating is very serious, and temperature rise is very fast, normally works just must carry out effective radiating and cooling to battery pack to make electrokinetic cell.In addition, hybrid electric bus may work as required at low ambient temperatures, and the optimum working temperature scope of lithium battery is 15-35 DEG C, and after 0 DEG C, the charge-discharge performance of lithium battery and cycle life can be greatly affected.For the power battery pack that hybrid electric bus uses, the charge-discharge magnification of low temperature does not all reach the requirement of use, and vehicle can be caused normally to use, and just needs to heat power battery pack when therefore using at low ambient temperatures.
Prior art great majority only have refrigerating function, and cooling medium has gas and liquid.No. 200810167815.3 patents provide the humidity control system scheme that a kind of existing cooling has again heating function, but this scheme needs condenser and ceramic heater, cost intensive and the electricity consumption burden that additionally increase is very large.
Utility model content
The utility model object is: provide one to have cooling and heating function simultaneously, meet the temperature regulating system of energy-conserving and environment-protective requirement.
The technical solution of the utility model is:
A kind of temperature regulating system, for regulating the battery pack temperature of hybrid electric bus, comprise pump, battery case body and the proportion adjustment triple valve connected successively by fluid line, described proportion adjustment triple valve comprises an inflow entrance and two flow exports, described inflow entrance connects battery case body by fluid line, two flow exports connect a cooler and a heat exchanger respectively by fluid line, cooler and heat exchanger connect pump respectively by fluid line, form circulation circuit, in fluid line, be filled with fluid media (medium).
Preferably, the fan airstream of the motor cooling water tank of hybrid electric bus connected by described cooler.
Preferably, the hot water stream that the engine-cooling system that hybrid electric bus connected by described heat exchanger is drawn.
Preferably, described proportion adjustment triple valve, by regulating the ratio of the fluid of cooler and heat exchanger, regulates proportion between 100:0 to 0:100.
Described fluid media (medium) is silicone oil.
The utility model has the advantages that:
Temperature regulating system provided by the utility model, adoption rate regulating three-way valve is by regulating the ratio of the fluid of cooler and heat exchanger, utilize radiator fan and the cooling water circulation system of engine of the motor cooling water tank that hybrid electric bus itself is equipped with, fluid medium carries out cooling and heating respectively, do not increase extra refrigerating plant or heater, make the fluid media (medium) being back to battery case temperature keep suitable scope, for battery provides a suitable operating ambient temperature, battery not only can be prevented overheated, special in cold district, also the normal use of battery can be ensured.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structure principle chart of temperature regulating system described in the utility model.
Embodiment
The temperature regulating system that the utility model discloses, for regulating the battery pack temperature of hybrid electric bus.As shown in Figure 1, comprise pump 2, battery case body 3 and the proportion adjustment triple valve 4 connected successively by fluid line 1, described proportion adjustment triple valve 4 comprises an inflow entrance and two flow exports, described inflow entrance connects battery case body 3 by fluid line, two flow exports connect cooler 5 and a heat exchanger 6 respectively by fluid line, cooler 5 and heat exchanger 6 are connected pump 2 respectively by fluid line and are formed circulation circuit, are filled with fluid media (medium) in fluid line.The actuating force that described pump 2 provides fluid media (medium) to circulate, described proportion adjustment triple valve 4 regulates the ratio of the fluid by cooler and heat exchanger.
Hybrid electric bus itself is equipped with radiator fan and the cooling water circulation system of engine of motor cooling water tank, is included in electromotor cooling system and engine-cooling system respectively, can directly quote its radiation air and hot water.The radiator fan of motor cooling water tank can provide the air-flow of a natural wind, and cooling water circulation system of engine, circulating hot water can be provided for heating.
The fan airstream of the motor cooling water tank of hybrid electric bus connected by described cooler 5, the hot water stream that the engine-cooling system that hybrid electric bus connected by described heat exchanger 6 is drawn.Segment fluid flow is in low temperature through radiator fan temperature, segment fluid flow passes through the hot water heat exchange circulating out with engine cool and is in high temperature, the fluid of mixing two kinds of different temperatures can obtain temperature and be in fluid between radiator fan air-flow and engine cool circulating hot water, the ratio changing mixing can regulate the temperature of fluid, with the circulating battery heat exchange be adjusted in the fluid of suitable temperature and battery case, battery just can be made close to suitable temperature.Described proportion adjustment triple valve 4, by regulating the ratio of the fluid of cooler and heat exchanger, regulates proportion between 100:0 to 0:100.Make the temperature of the fluid media (medium) being back to battery case near the scope of 15-35 DEG C, for battery provides a suitable operating ambient temperature.
