Air-Cooling Structure for Vehicle-Mounted Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In open cars with removable roofs, it is challenging to cool vehicle-mounted batteries effectively using outside air, as the temperature of outside air is higher than the air within the vehicle compartment, making it difficult to acquire a sufficient amount of air for cooling, especially in summer.
Innovation Solution
An air-cooling structure that includes an air suction part and an air flow introducing unit, where the air suction part is positioned behind a seat at the rear of the vehicle compartment and the air flow introducing unit directs air flowing above the vehicle compartment forward and downward to the air suction part, ensuring a sufficient air supply to the battery installation space, while an air deflector prevents air from entering the vehicle compartment, reducing noise and maintaining silence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If outside air is used to cool the battery in open cars with removable roofs, then the battery cooling function is provided, but the temperature of the outside air is higher and the amount of air intake is insufficient
Solution Approach 1:
The patent introduces an air suction part and air flow introducing unit as intermediary components to capture and direct air flows that pass above the vehicle compartment. These intermediaries enable the system to utilize ambient air movement without directly exposing the battery to hot outside air, thereby maintaining cooling effectiveness while managing air temperature and quantity
Solution Approach 2:
The patent replaces active mechanical cooling systems with a passive air flow utilization system. By positioning the air suction part to capture natural air flows passing above the vehicle compartment, the system substitutes complex mechanical cooling mechanisms with a simpler structure that leverages ambient air movement for battery cooling
2Quantity of substance
If air flow is directed to the air suction part, then sufficient air is supplied for cooling, but noise may enter the vehicle compartment
Solution Approach 1:
The patent segments the air flow path into distinct functional zones: an air suction part that captures air flow, an air flow introducing unit that directs it, and a battery cooling chamber. This segmentation allows the system to control air flow direction and prevent noise from the air intake path from entering the vehicle compartment while maintaining sufficient air supply for cooling
Solution Approach 2:
The air flow introducing unit acts as an intermediary component that directs air flow from the external environment to the battery cooling area while preventing noise transmission into the vehicle compartment. This intermediary structure enables the system to separate the air intake function from the noise exposure of the passenger space
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively cools the vehicle-mounted object by introducing a sufficient amount of air, preventing noise from entering the vehicle compartment, and ensuring silence, even when the roof is removed, and allows for continued cooling when the vehicle is stationary or the roof is mounted.
Implementation Method 1
an air flow which has passed above the vehicle compartment space and is flowed forward in the front and rear direction and downward in the upper and lower direction of the vehicle
Implementation Method 2
the air flows from the one end to the other end of the air suction part, that is, the air flows into the mounted object installation space. The vehicle-mounted object placed in the mounted object installation space is air-cooled by the air flow flowing in this manner

AI summary
There is provided an air-cooling structure for a vehicle-mounted object is capable of taking in a sufficient amount of air. The top end of an air suction part 36 is opened extremely near an air deflector 20 behind the air deflector 20. With this, an air flow W4 prevented from flowing to a vehicle compartment space 12 by the air deflector 20 is introduced to the top end of the air suction part 36 and flows into the interior of the air suction part 36. In this manner, the air flow W4 flowing at a speed corresponding to the running speed of a vehicle 10 flows into the interior of the air suction part 36, so that even though the air flow W4 is the outside air, the air flow W4 can effectively air-cool a battery 34 installed in a battery housing part 32.
