Problems solved by technology

[0010] However, if the air inlet is opened on the rear window sill, the air inlet will be close to the rear windshield and will be subjected to solar infrared radiation, so that the temperature of the air near the air inlet will increase, so that the temperature of the cooling airflow will increase. Elevated, resulting in the electronic equipment can not be effectively cooled

[0047] Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, the same components are marked with the same symbols and have the same names and functions, so detailed descriptions will not be repeated. Note that although the following description is directed to a cooling device for cooling a battery (the battery is an energy storage mechanism, and the energy storage mechanism is an electronic device) on a vehicle, the present invention is not limited thereto. The energy storage mechanism can also be a capacitor, not limited to a storage battery; the electronic device can be a PCU including an inverter, a DC / DC converter, etc., and is not limited to an energy storage mechanism (battery, capacitor, etc.). In the following explanation, it is assumed that the vehicle is a hybrid vehicle using an engine and an electric motor as driving forces, however, the vehicle may also be an electric vehicle (EV) (t...

[0081] FIG. 5 shows a vehicle cooling device 11000 mounted on a vehicle according to the present embodiment. Note that the same devices in Fig. 5 and Fig. 1 use the same symbols and have the same structure and function. Therefore, the detailed description will not be repeated here.

[0082] Referring to Fig. 5, Fig. 6 and Fig. 7, the plate-shaped element located on the rear window sill and capable of reflecting mid-infrared rays of solar radiation is described below: a reflector.

[0083] As shown in FIGS. 5 and 6, the reflective plate 11040 is located on the entire surface of the rear shelf. The reflector 11040 is a plate-shaped element consistent with the plane shape of the rear window platform, and its surface facing the rear windshield 2200 is processed into white or mirror to facilitate reflection of infrared rays.

[0084] In addition, as shown in FIGS. 5 and 7 , the reflection plate 11041 may also be arranged only near the air inlet 1030 of the rear window sill. The ...

Abstract

ECU executes a program including a step (S300) for operating a battery cooling fan motor if a battery temperature TH (BA) is higher than a cooling required temperature (YES in S200), a step (S500) for detecting the cooling wind temperature TH (FL), a step (S600) for detecting sun light intensity SUN to a rear package tray, and a step (S800) for operating a motor as an actuator for closing a rear sun shade as a sun light shading tool if TH (FL) > temperature threshold value and SUN > sun light intensity threshold value (YES in S700).

Description

technical field [0001] The present invention relates to a cooling device for electronic equipment (energy storage mechanism, energy conversion semiconductor element, and others) mounted on a vehicle. More particularly, the present invention relates to a cooling device for cooling electronic equipment installed at the rear of a vehicle by sucking air into the vehicle interior through an air intake installed inside the vehicle near a rear windshield. Background technique [0002] Vehicles have been developed and put into practical use equipped with a power train, which refers to a hybrid system consisting of an internal combustion engine (for example using the known gasoline or diesel engines) and an electric motor. Such vehicles are equipped with electronic devices such as energy storage mechanisms (battery or capacitors that drive the electric motor) and energy conversion devices (inverters or DC / DC converters). The charging and discharging of the battery is carried out thr...
