Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermostatic cooling systems struggle to maintain all heat generation sources in a storage space at the same operating temperature due to the use of a single type of cooling device, leading to inconsistent temperature regulation.
Innovation Solution
A composite thermostatic cooling system employing two types of cooling devices, including a liquid cooled air conditioner and a one-way or dual-phase immersion liquid cooling device, with a network of heat exchangers, tube loops, and temperature sensors to regulate the temperature of each heat generation source independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single type of cooling device is used to uniformly reduce the temperature of storage space, then the storage space temperature is reduced, but it becomes impossible for each heat generation source to maintain the same operating temperature uniformly
Solution Approach 1:
The cooling system is divided into multiple independent cooling zones, each equipped with its own cooling device and temperature control mechanism. Each heat generation source (battery module) has a dedicated cooling channel that can be independently controlled, allowing different temperature adjustments for different locations based on their specific heat generation characteristics.
Solution Approach 2:
Different cooling strategies are applied to different regions of the storage space based on local heat generation characteristics. The system uses temperature sensors to detect local temperature variations and adjusts cooling parameters (flow rate, temperature) for each cooling channel independently, ensuring each heat generation source receives appropriate cooling tailored to its specific needs.
2Power
If liquid cooled air conditioners are used to cool heat generation sources, then cooling capacity is provided, but inconsistent temperature regulation occurs across different sources
Solution Approach 1:
The system employs dynamic temperature control where cooling parameters are continuously adjusted based on real-time temperature feedback from sensors. Each cooling channel's flow rate and temperature are dynamically regulated according to the actual heat generation status of corresponding sources, enabling consistent temperature maintenance despite varying cooling demands.
Solution Approach 2:
Temperature sensors are installed in each cooling channel to monitor the temperature of heat generation sources. The control system receives this feedback information and automatically adjusts cooling parameters (flow rate, temperature) for each channel to maintain target temperatures, ensuring consistent temperature regulation across all sources.

AI summary
A composite thermostatic cooling system includes at least two types of cooling devices. A first type cooling device adjusts the temperature of a storage space, and the liquid coolant thereof circulates in a first tube loop with a first heat exchanger. A second type cooling device adjusts the temperature of each heat generation source in each storage box in the storage space, and the liquid coolant thereof circulates in a second tube loop with a second heat exchanger. The temperatures of the two coolants are adjusted by a refrigerant circulating in a third tube loop including: a branch connected to an expansion valve and the first heat exchanger, another branch connected to another expansion valve and the second heat exchanger, and a main loop connected to a compressor, a condenser, a dryer and the two branches. Thus, the temperatures of the heat generation sources are maintained to be the same.
