Solution Overview
Problem
Existing containerized heat recovery units for data centers face challenges in minimizing maintenance effort, reducing servicing costs, and improving accessibility and handling of heat exchangers, while also ensuring quick replacement and flexibility in adapting cooling power.
Innovation Solution
A containerized heat recovery unit design featuring a heat exchanger with vertically upwards pointing connections, allowing for easy servicing and replacement outside the container, combined with carrying means for horizontal insertion and extraction, facilitating simple and efficient maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heat exchangers are installed inside the container in conventional orientation, then the heat recovery unit can be compact and transportable, but maintenance and servicing become difficult and time-consuming
Solution Approach 1:
The heat exchanger is inverted so that its connections face upwards instead of downwards or sideways. This inversion allows service personnel to access connections from above while standing on the container floor, eliminating the need for ladders or complex positioning equipment and dramatically simplifying maintenance procedures
Solution Approach 2:
The connections are repositioned from horizontal or sideways orientation to vertical upward orientation. This dimensional change in connection orientation transforms the service access from a difficult horizontal/vertical combination to a simple vertical access from above, improving ergonomics and reducing service time
2Adaptability or versatility
If heat exchangers are fixed securely inside the container, then reliability and stability are improved, but replacement and upgrading become time-consuming
Solution Approach 1:
The heat exchanger is designed as a separate, modular component that can be independently removed and replaced. The carrying means enables the heat exchanger to be extracted as a complete unit without disturbing other system components, allowing quick replacement to adapt to changing cooling requirements or to replace failed units
Solution Approach 2:
The carrying means provides a dynamic extraction mechanism that allows the heat exchanger to be smoothly removed and repositioned. This dynamic capability enables the system to adapt to different operational requirements by easily swapping heat exchangers with different cooling capacities
3Ease of operation
If connections are positioned for compact installation, then space utilization is improved, but servicing requires complex positioning and increases time loss
Solution Approach 1:
The connections are positioned at an equipotential level for service personnel - all facing upwards at a height accessible from the container floor. This creates an equal working plane where all connection points are at the same ergonomic level, eliminating the need for awkward positioning or elevation changes during servicing

AI summary
Heat recovery unit including a transport container, comprising at least one heat exchanger arranged in the transport container with a lower end portion facing a container floor and an upper end portion with vertically upwards pointing connecting points for connecting the heat exchanger with a primary heat exchanging circuit and with a secondary heat exchanging circuit. Wherein carrying means are arranged in a lower area of the heat exchanger for enabling the insertion and extraction of the heat exchanger in a predominantly horizontal direction into and from the container in a sliding manner or in a rolling manner relative to the container.
