Description

Battery heat radiator for light mixed automobile

Technical Field

The utility model relates to a gently mix the car field, especially relate to a gently mix battery heat abstractor of car.

Background

The 48V light mixed automobile is characterized in that the voltage is increased to 48V on the 12V electric energy system level of the traditional fuel oil vehicle, and the integrated starting and power generation machine, the battery and the DC-DC voltage converter are added, so that the automobile has the functions of assisting the driving of the vehicle and reducing the burden of an internal combustion engine, meanwhile, the starting and stopping system is more stable in operation, and in addition, the effect of storing and recovering energy is also realized during braking, so that the aim of reducing the fuel consumption is fulfilled. Different from a new energy automobile and a traditional fuel oil automobile, due to the support of the large-load working conditions such as frequent starting of an engine and running of an air conditioner compressor during engine shutdown, the 48V battery capacity and the energy density are higher than those of a 12V battery of the traditional fuel oil automobile, and the heat dissipation capacity is higher than that of the traditional fuel oil automobile but lower than that of the new energy automobile. The traditional fuel vehicle has small battery capacity and small heat emission, so that the heat dissipation can be completed or the heat dissipation is not needed when the traditional fuel vehicle is placed in a front cabin of an automobile, and the heat dissipation can be completed only when a special cooling system is designed when the battery capacity of the new energy automobile is large and the energy density is high.

In the prior art, the battery heat dissipation mode of the light-mixed automobile is basically consistent with that of the traditional fuel oil automobile, namely, the battery of the light-mixed automobile is placed in the front cabin of the automobile and dissipates heat through airflow generated when the automobile runs, or the battery of the light-mixed automobile is placed in the trunk of the automobile and does not dissipate heat. However, the 48V battery has a high requirement on the ambient temperature, the discharge power of the battery is affected by a higher ambient temperature, and the energy saving effect of the whole 48V system and the stability of the system are further affected, in summer (ambient temperature is 30-40 ℃), the core temperature of the 48V battery can reach 65 ℃ (the limit high temperature is less than or equal to 55 ℃), the discharge power of the battery is greatly reduced, the heat dissipation of the 48V battery cannot be completed by the heat dissipation mode of the traditional fuel vehicle, especially, the air temperature on a road in summer is obviously higher than that of other positions, that is, the air flow blowing to the 48V battery is also high-temperature air flow when the vehicle runs in summer, and the cooling effect is extremely poor. If the new energy automobile battery heat dissipation mode is directly adopted, the production cost of the whole automobile can be greatly improved, obviously, the heat is not paid, and therefore, a special battery heat dissipation device for a light hybrid automobile is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can be effectively to gently mix the device that the 48V battery of car carries out the heat dissipation.

In order to achieve the above object, the utility model adopts the following technical scheme: a battery heat sink for a light-mix vehicle, a 48V battery is disposed on an intake or exhaust path of a blower, which is in communication with a cabin space.

In the above-described configuration, the air in the vehicle compartment is blown to the 48V battery, thereby dissipating heat from the battery. The temperature of the battery is guaranteed to be maintained below 55 ℃, and the discharge power, the energy-saving effect and the system stability of the battery are prevented from being influenced.

Detailed Description

The utility model provides a battery heat abstractor of light muddy car which characterized in that: the 48V battery is disposed on an intake or exhaust path of the blower 10, the intake path of the blower 10 communicating with the cabin space.

48V battery need not to dispel the heat in the lower season of temperature in above-mentioned scheme, and the member can open the air conditioner usually in the car in summer, and the air in the carriage just is the lower cold air of temperature like this, blows cold air to 48V battery through fan 10 and just can effectively accomplish its summer heat dissipation, can also heat 48V battery when winter simultaneously. The temperature of the battery is guaranteed to be maintained below 55 ℃, and the discharge power, the energy-saving effect and the system stability of the battery are prevented from being influenced.

Including being used for placing the seal box 20 of 48V battery, seted up air inlet 21 and carriage space intercommunication on the seal box 20, the gas outlet 22 of seal box 20 links to each other with the air inlet of fan 10 and forms the negative pressure, and the 48V battery is arranged on the air inlet path of fan 10. This placement of the 48V cells in the sealed box 20 effectively ensures that the venting efficiency is maintained, ensuring that the cool air is in contact with the cells as much as possible rather than being dispersed.

The outlet 11 of the fan 10 is communicated with the outside. The influence of hot air flowing through the 48V battery returning to the compartment on the refrigerating environment in the compartment is avoided.

The seal box 20 is arranged in the middle of the spare tire position of the trunk. The spare tire position of the vehicle trunk is an empty position, and the spare tire can be positioned while the seal box 20 is placed at the empty position.

The air inlet 21 of the seal box 20 is connected to an air inlet pipe 30, and an inlet 31 of the air inlet pipe 30 is opened at an upper portion of the cabin space. Because the cold air generally sinks in the carriage, the air circulation can be effectively completed by air intake from the upper part of the carriage, and the cold air is prevented from being drawn out too early to influence the air conditioning effect in the vehicle.

As shown in fig. 1 and 2, the air inlet pipe 30 comprises a transverse pipe 32 arranged along the lower part of the rear floor, and the transverse pipe 32 is connected with a vertical pipe 34 through a transition pipe 33, and the vertical pipe 34 is arranged on the inner side of the rear side wall of the vehicle body. The space in the vehicle compartment is communicated by the pipe line arranged along the inner surface of the vehicle body, and the pipe line itself is prevented from interfering with the vehicle compartment space.

The inlet 31 at the upper end of the vertical pipe 34 is arranged at the upper part of the trunk of the two-compartment car or the upper part of the rear seat of the three-compartment car. Because the air outlet of the automobile air conditioner is generally positioned at the front part of the automobile or the front part of a rear row of seats, the inlet 31 is arranged behind a passenger in the automobile, the influence of the system on the refrigeration effect of the air conditioner in the automobile is prevented, and the inlet 31 is arranged in the passenger cabin because a trunk of the three-compartment automobile is not communicated with the passenger cabin.

The air inlet pipe 30 and the air outlet pipe 24 are flat square pipes fitting the space in the vehicle. The car body structure is convenient to be attached.

The seal box 20 comprises a base 25 for connecting a 48V battery with a rear floor, a cover 26 is buckled on the base 25, and a gap for air circulation is reserved between the cover 26 and the 48V battery.

The base 25 and the cover 26 are provided with reinforcing ribs 23, and the length direction of the reinforcing ribs 23 on the upper part of the cover 26 is consistent with the air flow direction. The upper reinforcing ribs 23 are prevented from interfering with the airflow and obstructing the airflow.
