Buffer Storage for a Cooling Circuit of a Thermostatic Assembly and Thermostatic Assembly with a Buffer Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buffer storage systems for thermostatic assemblies in laboratory and climate chambers are inefficient in maintaining constant temperature and energy distribution, particularly when no throughflow occurs.
Innovation Solution
The buffer storage system incorporates a tank with a heat exchanger disposed within, allowing for the storage and adjustment of coolant without throughflow, and featuring a T fitting for selective coolant routing and a perforated sheet for uniform temperature distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a conventional buffer storage tank is used without internal heat exchanger, then the structure is simple, but the buffer storage cannot effectively store energy when no throughflow occurs
Solution Approach 1:
The heat exchanger is nested within the buffer storage tank, with the heat exchanger core positioned inside the tank interior and connected to the tank wall. This allows the buffer storage to perform dual functions: traditional coolant throughflow storage and active energy storage via the integrated heat exchanger, resolving the contradiction between energy storage capability and structural complexity
Solution Approach 2:
The buffer storage tank is designed to serve multiple functions: it acts as both a traditional buffer storage for coolant flow and an active thermal energy storage device through the integrated heat exchanger. This multi-functionality enables effective energy storage even when no coolant throughflow occurs, addressing the energy storage limitation of conventional single-function tanks
2Stability of the object's composition
If coolant is supplied centrally in the bottom region, then uniform temperature distribution is achieved, but the device requires additional routing complexity
Solution Approach 1:
The fourth tubeline supplies coolant to a specific localized region (bottom central area) of the tank rather than distributing it uniformly throughout. This localized supply point, combined with natural convection, creates uniform temperature distribution throughout the tank volume while maintaining relatively simple tubeline routing
3Use of energy by moving object
If the heat exchanger is disposed within the tank, then energy storage effectiveness is enhanced, but the tank interior space is reduced
Solution Approach 1:
The heat exchanger is nested within the tank interior space, utilizing the vertical and radial dimensions of the tank to position the heat exchanger core inside while connecting it to the tank wall. This nesting arrangement maximizes energy storage effectiveness without requiring separate external heat exchanger components, thereby optimizing the use of available tank volume

AI summary
A buffer storage for a cooling circuit of a thermostatic assembly includes a tank having a tank wall enclosing an interior volume and a heat exchanger including a first side with a first intake and a first discharge for a first coolant and a second side with a second intake and a second discharge for a second coolant. A first tubeline is guided through the tank wall to the first intake and a second tubeline is guided from the first discharge through the tank wall to an exterior volume. A third tubeline is guided through the tank wall to the second intake. The second discharge is connected across a T fitting with a fourth tubeline terminating in the interior volume. A fifth tubeline is guided through the tank wall and a sixth tubeline is guided from the interior volume through the tank wall to a thermostatic assembly outside the tank.
