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 mounted on a vehicle (a secondary battery as a storage battery or a fuel cell), and more particularly to a cooling structure for these batteries. Background technique [0002] A power supply unit (battery pack) having a relatively large-capacity secondary battery is mounted on a type of vehicle driven by a motor, such as an electric vehicle, a hybrid vehicle, and a fuel cell vehicle. Such a battery pack obtains a high voltage by connecting a plurality of lead storage batteries, nickel metal hydride batteries, lithium ion batteries, etc. in series. [0003] Generally, a combined secondary battery (battery module) composed of multiple (such as 6) single cells (such as a unit cell with an output voltage of 1.2V) connected and integrally connected in a battery pack is used to obtain the necessary power capacity (voltage value). Further, only a predetermined number of such battery modules are connected in series ...
