Engine Support Bracket Cooling via Transmission Oil Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing engine mounting structure fails to effectively dissipate heat from the engine support bracket, leading to thermal damage and inefficiency in cooling, as the bracket acts as a secondary heat source and the heat protector is unable to perfectly block heat transfer.
Innovation Solution
An engine support bracket with integrated cooling portions that utilize fluid flow, specifically through an expanded and shrunk tube configuration for transmission oil, and an air flow path to dissipate heat, allowing for stable cooling without a separate cooling device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the engine support bracket is used to fix the engine without integrated cooling, then the structure is simple and easy to manufacture, but heat accumulates in the bracket causing thermal damage and the bracket acts as a secondary heat source
Solution Approach 1:
The cooling function is merged into the engine support bracket by integrating cooling portions directly into the bracket structure. The cooling portions include cooling paths with expanded and shrunk tube portions that allow coolant flow, combining the structural support function with the thermal management function in a single integrated component.
Solution Approach 2:
The engine support bracket is designed to perform multiple functions simultaneously: it provides mechanical support for the engine and also serves as a heat dissipation device through its integrated cooling portions. This multi-functional design eliminates the need for separate cooling devices while maintaining both structural and thermal management capabilities.
2Temperature
If a separate cooling device is added to cool the engine support bracket, then heat dissipation effectiveness is improved, but the device complexity increases and power loss occurs
Solution Approach 1:
The engine support bracket cools itself through its own integrated cooling portions without requiring external power or separate cooling devices. The cooling paths are formed within the bracket structure itself, allowing coolant to flow through and dissipate heat directly at the heat source, eliminating the need for additional power-consuming cooling systems.
Solution Approach 2:
The cooling function is extracted from the concept of a separate cooling device and integrated directly into the engine support bracket structure. By taking out the cooling capability and embedding it within the bracket, the invention eliminates the need for independent cooling systems while maintaining effective heat dissipation.
3Object-affected harmful factors
If the heat protector is used to block heat from the starter motor, then the starter motor is protected from direct heat, but the heat protector cannot discharge accumulated heat and acts as a heat barrier itself
Solution Approach 1:
The cooling portions act as an intermediary thermal management system between the heat source (engine support bracket) and the heat protector. Instead of relying solely on the heat protector to block heat, the cooling portions actively manage heat flow by providing coolant pathways that dissipate heat before it accumulates, reducing the thermal burden on the heat protector.
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
Prevents heat accumulation in the engine support bracket, effectively discharges heat from the heat protector, and maintains cooling stability even if one cooling system fails, without power loss.
Implementation Method 1
the cooling portion is a cooling path which exchanges heat with the transmission oil flowing into the transmission oil supply pipe
Implementation Method 2
A flow velocity of the transmission oil passing through the expanded tube portion may be gradually decreased, a flow velocity of the transmission oil passing through the shrunk tube portion may be gradually increased

AI summary
An engine mounting structure is configured to includes an engine which is disposed in an engine compartment; an engine mount which fixes the engine to a vehicle body; and an engine support bracket which fixes a first side surface of the engine to the engine mount, in which the engine support bracket includes a cooling portion which cools the engine support bracket by use of a fluid flowing into the engine compartment.
