Integrated Pump-Reservoir Cooling Layout for Compact Heat Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As electrical devices such as computers and servers shrink in size, space and cost constraints limit the effectiveness of traditional heat mitigation methods, which often fail to adequately remove heat generated by increasing processing speeds and power consumption.
Innovation Solution
A system integrating a cold plate, heat exchanger, pump, motor, and reservoir, where the cold plate transfers heat to a circulating fluid, which is then directed to the heat exchanger for dissipation, with the pump and reservoir integrated to reduce space and fluid path length, and the motor is integrated within the pump to eliminate dynamic seals and enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional heat mitigation devices are used, then heat removal capability is provided, but space requirements and cost increase
Solution Approach 1:
The pump housing and reservoir are merged into a single integrated component, eliminating the need for separate pump and reservoir housings. This consolidation reduces the overall space occupied by the cooling system while maintaining all necessary functions of both components.
Solution Approach 2:
The motor is nested within the pump housing, with the motor shaft directly coupled to the impeller. This nested arrangement eliminates the need for external motor mounting and reduces the space required for the pump assembly, while still providing sufficient room for motor cooling fins.
2Temperature
If traditional heat mitigation devices are used, then heat removal capability is provided, but system cost increases
Solution Approach 1:
The integrated pump-reservoir housing reduces the total number of parts that need to be manufactured, assembled, and sealed. This consolidation simplifies the manufacturing process and reduces assembly costs while maintaining effective heat removal capability.
3Ease of operation
If separate pump and reservoir components are used, then maintenance access is provided, but fluid path friction and space increase
Solution Approach 1:
The pump and reservoir are integrated into a single housing with a common fluid cavity, eliminating the need for external fluid connections and reducing fluid path length. This integration minimizes friction losses while the serviceable top surface provides access for maintenance.
4Ease of operation
If motor is externally coupled to pump, then maintenance access is provided, but dynamic seals and space requirements increase
Solution Approach 1:
The motor is nested within the pump housing with direct coupling to the impeller shaft. This arrangement eliminates the need for dynamic seals between motor and pump, as the motor shaft becomes the pump shaft. The motor cooling fins extend through the pump housing to provide necessary cooling while maintaining a sealed fluid environment.
