Solution Overview
Problem
Conventional heat exchangers in high-speed computing systems suffer from reduced heat absorption capacity due to cooling liquid bypassing heat dissipation fins and high damping forces from pumps, leading to inefficient heat dissipation and increased volume.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional heat exchangers use Bernoulli's principle for cooling liquid flow, then the cooling liquid takes the shortest path between inlet and outlet, but the heat absorption capacity is greatly reduced because the cooling liquid does not pass through each heat dissipation fin
Solution Approach 1:
The water container is divided into multiple independent flow channels, each containing heat dissipation fins. The inlet water container has multiple inlet channels that distribute cooling liquid to different flow channels, ensuring the cooling liquid must pass through each heat dissipation fin rather than taking a single shortest path. This segmentation forces the cooling liquid to interact with all heat dissipation surfaces, significantly improving heat absorption capacity and dissipation efficiency.
2Length of moving object
If the pump conveying capacity is used with small-diameter tubes, then a large damping force is generated, but this requires larger inlet and outlet tubes which increase the heat exchanger volume
Solution Approach 1:
The patent transitions from a planar heat exchanger design to a three-dimensional multi-layer structure. Multiple flow channels are arranged in different layers (first water container and second water container) with corresponding inlet and outlet channels. This vertical stacking allows the use of smaller diameter tubes while maintaining adequate flow capacity, reducing the damping force generated by the pump and enabling a thinner overall heat exchanger profile.
3Area of stationary object
If a meandering water channel is used to maximize heat exchange area, then the cooling liquid path is lengthened, but the cooling liquid reaches temperature saturation in the middle section making rear section heat absorption worse and increasing panel thickness
Solution Approach 1:
Instead of using a single long meandering channel, the patent segments the heat exchange path into multiple shorter parallel channels. The first water container and second water container each have multiple inlet and outlet channels that create separate flow paths. This segmentation allows the cooling liquid to travel shorter distances in each channel while still covering a large total heat exchange area, preventing temperature saturation and maintaining efficient heat absorption throughout the system.
Solution Approach 2:
The patent uses a multi-layer vertical arrangement with first and second water containers stacked together. Heat exchange channels extend vertically between these layers, utilizing the third dimension (height) to maximize heat exchange area without increasing the horizontal path length. This three-dimensional channel arrangement allows short path lengths while achieving large heat exchange areas, solving the contradiction between area and path length.

The high-pressure water jet effect improves heat exchange rates, achieving low damping, high heat dissipation efficiency, and a thinner design, overcoming the limitations of conventional heat exchangers.
Implementation Method 1
The reduced control hole regulates the average flow rate and increases the speed of the water to bring a high-speed jet effect
Implementation Method 2
the cooling liquid will find the shortest path as the flow path between the liquid inlet pipe 3 and the liquid outlet pipe 4 due to Bernoulli's principle

AI summary
A thin heat exchange panel includes a contact side that is in contact with a heat source and a plurality of heat exchange channels disposed in the contact side. A water inlet channel of the heat exchange panel is connected with a high-pressure pump for inputting high-pressure water, and a water outlet channel of the heat exchange panel is connected with a cooler to form a circulating cooling system. When the high-pressure pump is started, the high-pressure water quickly enters the water inlet channel. Reduced control holes communicating with the water inlet channel are configured to regulate the average flow rate and increase the speed of the water to bring a high-speed jet effect, which improves the heat exchange rate of the water in the heat exchange channels to achieve the effects of low damping, high heat dissipation efficiency and thinning.
