Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional liquid cooling structures (two boards with machine-engraved waterways or welded heating/cooper pipes) are used, then cooling function is achieved, but manufacturing cost increases and production efficiency decreases
Solution Approach 1:
The patent merges the cooling plate and liquid flowing passages into a single integrally formed component. The cooling plate includes built-in liquid flowing passages that are formed as part of the plate structure itself, eliminating the need for separate waterway engraving or pipe welding operations. This integration directly resolves the contradiction by simplifying manufacturing while maintaining the cooling function.
Solution Approach 2:
The cooling plate serves multiple functions simultaneously: it provides structural support, acts as a heat dissipation component, and contains integrated liquid flowing passages for cooling fluid circulation. This multi-functionality eliminates the need for separate cooling channels or welded pipe structures, thereby reducing manufacturing complexity and cost while achieving effective cooling.
2Productivity
If traditional liquid cooling structures are used, then cooling function is achieved, but mass production suitability decreases
Solution Approach 1:
By integrating the liquid flowing passages directly into the cooling plate structure, the patent enables the entire cooling assembly to be manufactured as a single component or pre-assembled unit. This integration dramatically improves suitability for mass production by eliminating time-consuming assembly steps such as welding or sealing ring installation, allowing for rapid manufacturing and assembly in production environments.
3Temperature
If water cooling technology is applied to LED lamps, then heat dissipation is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent combines the cooling plate with integrated liquid flowing passages into a unified structure that provides effective water cooling for LED lamps. The passages are formed as part of the plate structure, eliminating the need for separate cooling channels or welded pipe systems. This integration maintains superior heat dissipation performance while significantly reducing structural complexity and manufacturing cost.

AI summary
Disclosed is an easily shaped liquid cooling heat-dissipating module of an LED lamp, comprising a cooling body (1), and two plugs (2, 3), wherein the cooling body (1) is formed with liquid flow passages (11, 12, 13). The number of liquid flow passages (11, 12, 13) is multiple, liquid inlet ends of respective liquid flow passages (11, 12, 13) are located at the same end of the cooling body (1) as liquid outlet ends of the adjacent liquid flow passages. A liquid inlet end of a first-stage liquid flow passage (11) is connected to a liquid inlet hole (21) arranged on a plug (2), with the plug (2) being at the end where the liquid inlet end is located, a liquid outlet end of a last-stage liquid flow passage (13) is connected to a liquid outlet hole (31) arranged on a plug (3), with the plug (3) being at the end where the liquid outlet end is located, and liquid inlet ends of other stages of liquid flow passage, apart from the first-stage liquid flow passage (11), respectively communicate with liquid outlet ends of upper stage liquid flow passages via connecting grooves (22, 23) arranged on the plugs (2, 3), with the plugs (2, 3) being at the end where the liquid outlet end is located. Alternatively, the number of liquid flow passage is one. A liquid inlet end of the liquid flow passage is connected to a liquid inlet hole (21) arranged on one plug (2) therein, and a liquid outlet end is connected to a liquid outlet hole (31) arranged on the other plug (3). Thus, a simple process and low costs are achieved, and it is easy to realize mass production.
