Solution Overview
Problem
Existing air conditioners face low heat dissipation efficiency and safety hazards due to the design of heat sinks, which are often made of aluminum alloy with sharp edges, and cannot effectively discharge heat from the electrical control module, leading to potential overheating and short circuits.
Innovation Solution
The air conditioner incorporates a heat dissipation unit with a flow guide member and heat dissipation assembly, forming an air intake region and a smaller air discharge region, increasing air velocity and improving heat dissipation efficiency, while also preventing liquid ingress through a gathering region formed by the flow guide portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat sinks are used to dissipate heat from the electrical control module, then heat dissipation is achieved, but the heat dissipation efficiency is low because the heat cannot be completely discharged from the housing
Solution Approach 1:
The patent extracts the heat dissipation function from the traditional heat sink design and separates it into two parts: a first heat dissipation component inside the housing and a second heat dissipation component outside the housing. The second component is specifically extracted to discharge heat from the housing through the air outlet, thereby improving overall heat dissipation efficiency and ensuring complete heat discharge.
Solution Approach 2:
The patent introduces a spatial dimension change by placing part of the heat dissipation system outside the housing. The second heat dissipation component extends from the housing exterior to the air outlet, creating a three-dimensional heat dissipation pathway that utilizes both internal and external space, thereby improving heat discharge completeness.
2Loss of energy
If traditional heat sinks made of aluminum alloy are used, then heat dissipation structure is provided, but sharp acute-angled edges pose safety hazards
Solution Approach 1:
The patent applies curvature by rounding the edges of the heat dissipation components. The first and second heat dissipation components are designed with rounded edges instead of sharp acute-angled edges, eliminating safety hazards while maintaining the heat dissipation capability of the aluminum alloy material.
3Speed
If the air discharge region area is made smaller than the air intake region area, then air velocity increases improving heat dissipation, but the design complexity increases
Solution Approach 1:
The patent applies local quality by creating a flow guide member with non-uniform cross-sectional area. The air discharge region is designed with a smaller area than the air intake region, creating a localized constriction that accelerates air flow through the heat dissipation components. This local geometric modification increases air velocity and heat dissipation efficiency without requiring complex mechanical systems.
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 configuration enhances heat dissipation efficiency by increasing air velocity through the heat dissipation assembly and prevents liquid from entering the electrical control module, thereby improving both heat management and waterproof performance.
Implementation Method 1
the flow guide member and the heat dissipation assembly form an air discharge region at a position close to the air outlet, and the flow guide member and the heat dissipation assembly form an air intake region at a position remote from the air outlet, so that at least a part of air flowing through the heat dissipation assembly passes through the air intake region, the air discharge region and the air outlet in sequence
Implementation Method 2
During the operation of the air conditioner, the electrical control module will generate a large amount of heat. If the heat is not dissipated in time, it may cause overheating or even short circuit of the electronic control module. Therefore, a corresponding heat dissipation device is required to be provided to take the heat away.
Implementation Method 3
the flow guide portion forms a gathering region on a surface remote from the electrical control module so as to block liquid from entering the electrical control module through the heat dissipation assembly
