Vehicle Airflow Guide Layout for Uniform Heat Exchanger Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air conditioners struggle with uniform air distribution and accurate airflow rate control, leading to inconsistent comfort levels within vehicle interiors.
Innovation Solution
The proposed vehicle air conditioner design includes a blower device connected to an air conditioning device with a heat exchange core divided into two parts by a partition wall. An air guide is installed to direct high-velocity air from the blower device towards the second core part, ensuring uniform air distribution and adjustable airflow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air is blown directly from the blower device without guidance, then the air flow rate is high, but the air distribution is non-uniform and comfort is reduced
Solution Approach 1:
An air guide structure is introduced as an intermediary component between the blower device and the heat exchange core. This air guide redirects high-velocity air from the blower toward the second core part, mediating the air flow to achieve more uniform distribution across both core parts while maintaining high airflow rates
Solution Approach 2:
The heat exchange core is divided into two distinct core parts (first core part and second core part) using a partition wall. This segmentation allows differential air flow management, with the air guide specifically directing air to the second core part to balance the distribution across both segments
2Manufacturing precision
If the heat exchange core is divided into two parts with a partition wall, then air distribution is improved, but the device complexity increases
Solution Approach 1:
The heat exchange core is segmented into two core parts by a partition wall, enabling differentiated air flow paths. This segmentation improves air distribution uniformity by allowing the air guide to specifically target the second core part with high-velocity air while the first core part receives air more directly from the blower
Solution Approach 2:
The air guide serves as a mediating structure that manages the complexity introduced by the partition wall. It simplifies the overall system by providing a straightforward mechanism to direct air flow to the second core part, compensating for the added complexity of the partitioned core design

AI summary
An embodiment vehicle air conditioner includes an air conditioning device connected to a blower device to receive air supplied from the blower device, a heat exchange core provided in the air conditioning device and disposed in parallel with a flow direction of the air supplied from the blower device, a partition wall disposed to divide the heat exchange core into a first core part disposed to be close in distance to the blower device and a second core part disposed to be distant from the blower device, such that the air supplied from the blower device is distributed and supplied to the first core part and the second core part, and an air guide provided in a connection portion between the blower device and the air conditioning device and configured to guide the air to be supplied to the second core part of the heat exchange core.
