no. 1 Embodiment approach

[0189] figure 1 It is a schematic block diagram of the front part of the vehicle 10 in 1st Embodiment of this invention. Among them, in figure 1 Among them, the arrow F direction indicates the front side of the vehicle front-rear direction, the arrow U direction indicates the upper side of the vehicle vertical direction, and the directions perpendicular to the arrow F direction and the arrow U direction respectively indicate the vehicle width direction.

[0190] An engine 14 is provided in an engine compartment 12 at the front of the vehicle 10 . In addition, in the engine compartment 12 of the vehicle 10 , a cooling device 16 is provided on the vehicle front side of the engine 14 .

[0191] The cooling device 16 includes, as a heat exchanger for cooling, an engine radiator 18 through which engine cooling water circulates between the engine 14 and a condenser 20 that forms a cooling cycle of an air conditioner (air conditioner) not shown in the figure. It is used to circu...

no. 2 Embodiment approach

[0248] Next, a second embodiment of the present invention will be described. Here, the basic configuration of the second embodiment is the same as that of the above-mentioned first embodiment, and in the second embodiment, the same reference numerals are assigned to the same members as in the first embodiment, and description thereof will be omitted.

[0249] In the above-mentioned first embodiment, whether the engine radiator 18 and the condenser 20 have reached the specified cooling capacity is judged by the running vehicle speed v, and when there is a possibility that the specified cooling capacity cannot be obtained, the condenser 20 is used to cool the engine. Medium pressure P, to confirm whether the condenser 20 has obtained the cooling capacity corresponding to its cooling load. On the other hand, in the second embodiment, it is confirmed whether or not the cooling capacity corresponding to the cooling load is obtained for the engine radiator 18 and the condenser 20 re...

no. 3 Embodiment approach

[0261] Next, a third embodiment of the present invention will be described. The basic configuration of the third embodiment is the same as that of the above-mentioned first and second embodiments, and in the third embodiment, the same reference numerals are assigned to the same components as those of the first and second embodiments, and their components are omitted. illustrate.

[0262] Figure 5 It is a schematic diagram of main parts of a vehicle 10A according to the third embodiment. This vehicle 10A is a hybrid vehicle, which can run by an electric motor (both not shown) in addition to the engine 14 .

[0263] A cooling device 50 is provided in the engine room 12 of the vehicle 10A. As the cooling heat exchanger of the cooling device 50, in addition to the engine radiator 18 and the condenser 20A, a radiator (hereinafter referred to as HV radiator 52) for cooling the inverter device is provided. The electrical energy stored in the battery is converted into electrical ...

Abstract

The invention provides a cooling device for a vehicle, which is located on the vehicle having engine controller. The said engine controller stops the engine when the engine stopping condition is established, and restarts the engine when the engine restarting condition is established. The cooling device cools the coolant medium in heat exchanger through cooling air imported from outside of the vehicle using cooling device. Based on the preestablished condition, the driving force of engine or any one of engine is selectively used to perform cooling.

Description

technical field [0001] The present invention relates to a cooling device for a vehicle that cools a cooling medium using cooling heat exchangers such as an engine radiator and a condenser installed on the vehicle. Background technique [0002] In a vehicle, for example, an engine radiator for cooling engine cooling water, and a cooling heat exchanger (hereinafter referred to as a cooling heat exchanger) such as a condenser as a cooling heat exchanger of a vehicle air conditioner (hereinafter simply referred to as an air conditioner) are provided in an engine room. referred to as heat exchanger). The air in front of the vehicle is introduced as cooling air, and the introduced cooling air passes through the engine radiator and condenser to cool the cooling water and the cooling medium for the air conditioner. [0003] In recent years, for the purpose of reducing fuel consumption, vehicle emissions, and noise, vehicles using idle stop control that stops the engine when the veh...
