Closed-Type Liquid Cooling Motor Frame Sand Core Casting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional open-type liquid-cooling motor frames face tightness failures due to machining precision and gasket service life issues, leading to reduced efficiency and increased energy consumption.
Innovation Solution
A closed-type liquid-cooling motor frame is manufactured using a sand core and mold connection to form a closed water channel, with core-head members creating a water inlet, outlet, and sand-expelling holes, and screw bolts locking the frame to enhance tightness and service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an open-type liquid-cooling motor frame is produced by casting process with opened water channel, then the manufacturing process is simple, but the tightness reliability deteriorates due to joint surface machining precision and gasket service life issues
Solution Approach 1:
The invention extracts the problematic joint surfaces and gaskets from the water channel sealing system. By forming the water channel as a closed cavity within the motor frame body during casting, the need for separate joining components and gaskets is eliminated, thereby removing the sources of tightness failure while maintaining manufacturing simplicity
Solution Approach 2:
The invention merges the water channel sealing function directly into the motor frame structure. The closed water channel is integrated as an internal cavity of the frame body, combining the structural component with the sealing function, thereby eliminating the need for separate sealing components and improving tightness reliability
2Ease of manufacture
If joint surfaces and gaskets are used to seal the opened water channel, then the manufacturing process is straightforward, but the service life deteriorates due to gasket degradation over time
Solution Approach 1:
The invention replaces the disposable gasket (which degrades over time) with a permanent integrated closed water channel structure. The closed channel is formed as part of the motor frame body during casting, creating a durable sealing solution that eliminates the need for replaceable sealing components
Solution Approach 2:
The sealing function is merged into the motor frame structure itself. The closed water channel is formed as an internal cavity during the casting process, integrating the sealing function permanently into the frame body and eliminating time-dependent degradation issues
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
The method significantly enhances tightness and extends service life by creating a sealed water channel, preventing long-term usage failures and maintaining motor efficiency.
Implementation Method 1
applying a casting process to produce a frame casting according to the mold, the main portion and the plurality of core-head members
Implementation Method 2
pressurizing a fluid into the closed water channel via the water inlet, and then the fluid carrying the rest of the sand core to leave the closed water channel

AI summary
A method includes: forming a sand core including a main portion and core-head members connecting the main portion; applying a casting process to produce a frame casting having a first end, a first-end inner wall, a second end, a second-end inner wall, a closed water channel between the first-end inner wall and the second-end inner wall, a water inlet, a water outlet and sand-expelling holes at the first end; shaking the frame casting to have part of the sand core to leave the closed water channel via the water inlet, the water outlet and the sand-expelling holes; pressurizing a fluid into the closed water channel via the water inlet to carry the rest of the sand core to leave the closed water channel via the sand-expelling holes and the water outlet; and applying screw bolts to lock the sand-expelling holes to manufacture a closed-type liquid-cooling motor frame.
