Abstract
(EN)
This storage battery cooling device makes it possible to sufficiently cool the vicinity of the terminal area of the battery cells. This cooling device (1) is provided with: a cooling unit (2) which extends along a wall surface of the storage battery, comprises internal flow paths (23a-d) arranged in parallel through which a refrigerant flows, and cools the storage battery from the wall surface side; and a supply unit (3) which supplies a refrigerant to the cooling unit along a direction perpendicular to the wall surface. Furthermore, a supply hole (24) is formed in the cooling unit (2) such that the flow speed in a flow path (23a) provided in a position a short distance from the terminal area of the storage battery is faster than the flow speed in the flow path (23d) provided in a position a long distance from the terminal area.

L'invention concerne un dispositif de refroidissement pour accumulateur qui permet de refroidir suffisamment les alentours d'une partie borne de cellules électriques. Le dispositif de refroidissement (1) de l'invention est équipé : d'une partie refroidissement (2) qui se prolonge suivant une face paroi d'un accumulateur, dans la partie interne de laquelle des trajets d'écoulement (23a à d) destinés à l'écoulement d'un réfrigérant, sont formés en parallèle, et qui refroidit l'accumulateur depuis le côté face paroi ; et d'une partie alimentation (3) qui alimente en réfrigérant la partie refroidissement suivant une direction perpendiculaire à la face paroi. Enfin, un orifice d'alimentation (24) est formé dans la partie refroidissement (2) de sorte que le trajet d'écoulement (23a) agencé en un endroit à courte distance de la partie borne de l'accumulateur, présente une vitesse d'écoulement supérieure à celle au niveau du trajet d'écoulement (23d) agencé en un endroit à longue distance de la partie borne.

 本発明は、蓄電池の冷却装置において、単電池の端子部付近を十分に冷却することを可能にしたものである。 本発明の冷却装置(1)は、蓄電池の壁面に沿って延設され、内部に冷媒が流れる流路(23a~d)が並列して形成され、壁面側から蓄電池を冷却する冷却部(2)と、壁面と直交する方向に沿って冷却部に冷媒を供給する供給部(3)とを備える。さらに、冷却部(2)には、蓄電池の端子部からの距離が短い箇所に設けた流路(23a)が,端子部からの距離が長い箇所に設けた流路(23d)における流速よりも高くなるように供給孔(24)が形成される。
