Title:
車載用バッテリの温調装置
Document Type and Number:
Japanese Patent JP7227071
Kind Code:
B2
Abstract:
To solve such a problem in a conventional cooling device 100 of a vehicular battery that efficiency of heat exchange with a battery cell 106 is deteriorated caused by stagnation of bubbles generated by cavitation in an upper portion of a cooling tank 103.SOLUTION: A temperature adjustment device 10 for an on-vehicular battery 12 comprises: a temperature adjusting plate 21; a fluid circulation pipe conduit 23 connected to the temperature adjusting plate 21; a reservoir tank 24, a condenser 25, a pump 26, a pulsation generating mechanism 27, and an air detection mechanism 28 that are disposed in the fluid circulation pipe conduit 23; and a control unit 29 controlling the pulsation generating mechanism 27 and the like on the basis of a detection signal detected by the air detection mechanism 28. The pulsation generating mechanism 27 generates pulsation in temperature adjusting fluid 33 to remove an air layer 35 when there is the air layer 35 in the temperature adjusting plate 21, therefore heat exchange efficiency between a battery cell 12B and temperature adjusting fluid 33 is improved.SELECTED DRAWING: Figure 2
