Double-Sided Liquid Cooling Head With Split Channels for Parallel Heat Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with thinner designs face challenges in effective heat dissipation due to increased heat generation and limited space for heat dissipation structures, particularly when circuit boards or chips are arranged in parallel, leading to interference between multiple heat dissipation structures.
Innovation Solution
A double-sided cooling liquid cooling head with a frame, baffle, and two covers, each with fin groups and heat-conduction blocks, separates the cooling space into two independent areas to dissipate heat from two heat sources simultaneously using a coolant that flows through separate channels in each area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If circuit boards or chips are arranged in parallel to reduce device size, then the area for arranging electronic components increases, but interference between multiple heat dissipation structures occurs
Solution Approach 1:
The cooling head is segmented into two independent cooling chambers by a baffle, with each chamber handling heat dissipation for one heat source. This segmentation eliminates interference between heat dissipation structures while maintaining a compact integrated design, directly resolving the contradiction between reduced device size and avoided structural interference.
2Temperature
If heat dissipation structures are increased to handle higher heat generation, then heat dissipation performance improves, but the available space inside the device is insufficient
Solution Approach 1:
Two independent cooling chambers are merged into a single integrated cooling head assembly that can be mounted on both sides of a heat source. This merging allows effective heat dissipation for two heat sources simultaneously without requiring separate cooling structures, thereby improving heat dissipation performance while conserving device space.
3Device complexity
If a single cooling structure is used for one heat source, then the structure is simple, but it cannot dissipate heat from two heat sources simultaneously
Solution Approach 1:
The cooling head is designed with multi-functionality to serve dual purposes: it contains two independent cooling chambers that can simultaneously dissipate heat from two different heat sources. Each chamber can be independently configured with fins and heat conduction blocks, allowing the single cooling head assembly to handle multiple thermal loads without requiring multiple separate cooling structures.

AI summary
A double-sided cooling-liquid cooling head has a frame, a baffle, a first cover, and a second cover. The frame has two side strips and two connecting strips connected to each other to form an accommodating space. The connecting strips separately has an inlet and an outlet. The baffle is fixed in the frame to separate the accommodating space to a first and a second space. The inlet and the outlet are communicated to the first space and the second space. The first cover is fixed on a side of the frame and has a first fin group located in the first space and abutted against the baffle. The second cover is fixed on another side of the frame and has a second fin group located in the second space and abutted against the baffle. The first cover and the second cover are used to cool two heat sources.
