Dual-Pump Radiator Layout for Shorter Liquid Cooling Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling devices have a lengthy configuration due to the placement of centrifugal pumps at both ends of the radiator, increasing the proportion of non-radiator components and reducing heat dissipation performance.
Innovation Solution
A heat dissipation device with a radiator, a first tank, and a pump assembly where the pump assembly is located on one side of the radiator, featuring a first pump, a second pump, and a flow path portion that guides liquid circulation, reducing the length of non-radiator components and enhancing heat dissipation performance by increasing the radiator's length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two centrifugal pumps are disposed at both ends of the radiator, then the liquid circulation is ensured, but the total length of the cooling device increases
Solution Approach 1:
The patent combines two separate pump units into a single integrated pump assembly that houses both pumps within one structure. This merging allows the pumps to be positioned on one side of the radiator rather than distributed at both ends, thereby reducing the overall length of the cooling device while maintaining the liquid circulation function provided by the two pumps
2Power
If the proportion of non-radiator components is increased, then the pump function is enhanced, but the heat dissipation performance is reduced
Solution Approach 1:
The patent repositions the pump assembly from a distributed configuration at both ends of the radiator to a concentrated configuration on one side. This spatial reorganization in one dimension (longitudinal position) allows the non-radiator components to occupy less space along the length of the device, thereby increasing the proportion of radiator components and improving heat dissipation performance while maintaining pump functionality

AI summary
A heat dissipation device includes a radiator, a first tank, and a pump assembly. The radiator cools liquid and extends in a first direction. The first tank is connected to the radiator, and the liquid passes through the first tank. The pump assembly is connected to the first tank and circulates the liquid flowing in from the first tank. The radiator includes a pipe through which the liquid passes. The pipe extends along the first direction. The pump assembly is located on one side in the first direction of the radiator. The pump assembly includes a first pump, a second pump, and a flow path portion. The first pump feeds and circulates the liquid. The second pump feeds and circulates the liquid. The flow path portion guides the liquid fed from the first pump and the second pump toward an outside of the pump assembly.
