Heat Exchanger Mounting Device Augmented Head Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat exchanger mounting devices in electronic systems face issues with debris creation due to fastener wear from multiple torque cycles, leading to potential electronic component failure and time-consuming screwing processes, especially when mounting multiple heat exchangers on a circuit board.
Innovation Solution
A heat exchanger mounting device system featuring a device plate with openings, securing devices with augmented heads and cages, where the augmented head extends through the cage opening and rotates to secure the heat exchanger without screwing, using a pin and spring mechanism to support the weight, eliminating the need for screws and reducing installation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fasteners are secured by screwing via a screwdriver, then the heat exchanger mounting device can be attached to the heat exchanger, but the fasteners wear and create debris that may cause electronic components to fail
Solution Approach 1:
The patent replaces the traditional screwing mechanical system with a push-button fastening system. The fasteners are secured by pushing the augmented head through the cage opening and rotating it 90 degrees, eliminating the need for screwdrivers and multiple torque cycles. This substitution removes the wear and debris generation associated with traditional screwing while maintaining secure attachment.
2Strength
If multiple fasteners are screwed to secure the heat exchanger mounting device, then the attachment is secure, but the screwing process is time consuming
Solution Approach 1:
The augmented head is designed with a pre-configured structure that allows the fastening action to be prepared in advance. The user simply pushes the augmented head through the cage opening and rotates it 90 degrees, a motion that is pre-determined by the design. This eliminates the time-consuming process of selecting screwdrivers, applying torque, and checking tightness associated with traditional screwing.
3Strength
If traditional screwing is used to attach the heat exchanger mounting device, then the attachment is secure, but the process requires screwdrivers and multiple torque cycles
Solution Approach 1:
The patent extracts the essential function of fastening from the complex screwing process. By removing the need for screwdrivers, multiple torque cycles, and torque checking, the invention isolates the core fastening action to a simple push-and-rotate motion. The augmented head design inherently provides the attachment strength without requiring external tools or complex procedures.

AI summary
A heat exchanger mounting device including a device plate, at least one securing device, and at least one cage is provided. The at least one securing device includes a barrel and pin. A first barrel end of the barrel is incorporated in at least one opening of the device plate. An augmented head of the pin extends at least partially through and rotatable in the barrel. The at least one cage is mounted on a heat exchanger. The augmented head extends through a cage opening of the at least one cage in a first direction. The augmented head rotates within the at least one cage in a second direction to secure the at least one securing device to the heat exchanger. The weight of the heat exchanger is substantially supported by the at least one securing device by way of the at least one cage and augmented head.
