first embodiment

[0069]First of all, the first embodiment will be explained below.

[0070](1) Outline of Arrangement of Battery Cooling Device and Air Conditioner for Vehicle Use

[0071]The battery cooling device 1 for vehicle use of this embodiment is applied to a hybrid powered automobile provided with an internal combustion engine and electric motor which are used for driving the automobile. This hybrid powered automobile includes a front seat side air conditioner (not shown) and a rear side air conditioner 2. Referring to FIG. 1, explanations will be made into an outline of the battery cooling device 1 and the rear seat side air conditioner 2 for vehicle use of this embodiment. FIG. 1 is an arrangement view showing a model of the battery cooling device 1 and the rear seat side air conditioner 2 for vehicle use. In this connection, the front seat side air conditioner for vehicle use is arranged in a front seat side space of the vehicle and mainly conducts air-conditioning on the front seat side in th...

third embodiment

[0138]In the same manner as that of the third embodiment, it is set that when temperature Tam of the air outside the vehicle passenger compartment is raised higher, reference temperatures Tb—th5 and Tb—th6 are decreased.

[0139]In this embodiment, in the case where temperature Tam of the air outside the vehicle passenger compartment is higher than predetermined temperature Tam—th and battery temperature Tb is not less than reference temperature Tb—th6, controlling may be conducted so that a volume of air blown out by the blower can be increased.

[0140]In this connection, in the third embodiment and this embodiment, in the same manner as that of the first and the second embodiment described above, in the vehicle having both the front seat side air conditioner and the rear seat side air conditioner, the battery cooling device uses the cooling air cooled by the evaporator which is a cooling means incorporated into the rear seat side air conditioner. However, the present invention is not l...

fifth embodiment

[0141]Next, referring to FIGS. 10 to 20, the air conditioner for vehicle use of the present invention will be described as follows.

[0142](3) Arrangement of Air Conditioner for Vehicle Use

[0143]First of all, referring to FIG. 10, the arrangement of the air conditioner for vehicle use will be explained below. FIG. 10 is a view showing a model of the overall arrangement of the air conditioner for vehicle use. In this connection, the void arrow in FIG. 10 shows a flow of air. This air conditioner for vehicle use includes an air conditioning unit 102, a battery cooling unit 101 and ECU (control means) 119.

[0144](3.1) Air Conditioning Unit 102

[0145]The air conditioning unit 102 is arranged on the rear seat side and conducts air-conditioning mainly on the rear seat side. As shown in FIG. 10, this air conditioning unit 102 includes an air-conditioning case 121, evaporator (cooling air generating means) 123, heater core (heating air generating means) 122, air mixing door (conditioned air gen...

Abstract

The air suction mode can be switched among the inside air mode in which the air sucked by the battery cooling blower 15 to cool the battery 3 for vehicle use is the air inside a vehicle passenger compartment, the outside air mode in which the air sucked by the battery cooling blower 15 is the air outside the vehicle passenger compartment and the cooling air mode in which the air sucked by the battery cooling blower 15 is the air cooled by an evaporator of the rear seat side air conditioner 2.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 11 / 252,275 filed on Oct. 17, 2005.
