Problems solved by technology

Therefore, the distance from the air intake port to the cooling fan is long, and the longer the distance is, the harder it is for the occupants to hear the noise generated by the cooling fan.
However, if the distance between the cooling fan of the cooling duct and the suction port is long, the pressure loss of the duct due to duct resistance increases, and a powerful cooling fan is required.
This leads to an increase in the size of the cooling fan or an increase in the noise of the cooling fan
[0014] In this way, if the distance between the cooling fan and the cooling air intake in the vehicle compartment is close, the occupants will feel uncomfortable due to the noise, and if the distance is long, a high-power fan is required.

Abstract

The invention provides a battery cooling structure, comprising: a blower fan (26) for sucking the cool air of cooling battery part (100) from the inlet (22A) of carriage; a sucking channel (22B) with first bended part (202) and second bended part (204) connected to the inlet (22A) and blower fan (26); and acoustic absorbent mounted on the first beaded part (202) and second bended part (204) for absorbing the noise of blower fan.

Description

Technical field [0001] The present invention relates to a battery (a secondary battery or a fuel cell used as a storage battery) mounted on a vehicle, and particularly relates to the cooling structure of these batteries. Background technique [0002] In electric vehicles, hybrid vehicles, fuel cell vehicles, and other types of motor-driven vehicles, a power supply unit (battery pack) of a secondary battery with a relatively large capacity is mounted. Such a battery pack obtains a high voltage by connecting a plurality of lead-acid batteries, nickel-hydrogen batteries, lithium-ion batteries, or the like in series. [0003] Generally, a combined secondary battery (battery module) formed by connecting multiple single cells (e.g., a unit cell with an output voltage of 1.2V) (e.g., six) in an integrated manner is used in battery packs to obtain the necessary The power capacity (voltage value). Such battery modules are further connected in series only by a predetermined number to form ...
