Abstract

In order to simplify the assembly of a battery back while adopting a configuration which efficiently cools heat-generating parts, a battery pack is provided with a main circuit board (40) which is connected to a unit cell (11) of the battery block (10), and with a slab-shaped radiator block (42) which is fixed to the heat-generating part (41) in a heat-coupled state. An encapsulating case (30) is formed in a box shape with a greater width than thickness, and comprising two surface plates (33) facing one another and sidewalls which close-off the outer periphery of said surface plates (33). The radiator block (42) is separated on the inside of the encapsulating case (30) so as not to overlap with the battery block (10), and the radiator block (42) is positioned in the inside of the encapsulating case (30) in parallel with the surface plate (33) and in a heat-coupled state with the surface facing the surface plate (33). The heat generated by the heat-generating part (41) is absorbed by the radiator block (42) and radiated from the surface plate (33).

Description

technical field [0001] The present invention relates to a battery pack formed by accommodating a battery block and a heat-generating component in an outer case, and more particularly to a battery pack capable of efficiently dissipating heat from the heat-generating component, wherein the battery block is formed by combining a plurality of rechargeable cells. The battery is accommodated in the battery holder, and the heat generating member is connected to the battery of the battery block. Background technique [0002] The battery pack can increase the output voltage by connecting a plurality of batteries in series, or increase the output current by connecting a plurality of batteries in parallel. Since heat-generating components such as transistors such as FETs and diodes are accommodated in the battery package, it is particularly important to efficiently dissipate heat from these heat-generating components. This is because an abnormal temperature rise of the heat-generating...
