Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator inner containers suffer from poor temperature equalization and heat conduction due to local cooling and slow heat exchange rates, leading to increased complexity and cost in achieving uniform temperature distribution.
Innovation Solution
A temperature homogenizing container with capillary tube cavities and a micro-tooth structure within a highly heat-conductive material body, allowing for efficient heat exchange medium flow, enhancing heat transfer and reducing temperature differences across the accommodating space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional inner container structure with poor heat conduction is used, then manufacturing is simple, but temperature equalization effect is poor and cooling capacity leaks
Solution Approach 1:
The container body is segmented into multiple capillary tube cavities distributed throughout its structure. These cavities divide the heat exchange function into multiple parallel channels, allowing heat to be distributed and equalized across different regions of the container simultaneously, thereby improving temperature uniformity without requiring complex external cooling systems
Solution Approach 2:
The container incorporates a capillary tube cavity structure that functions as a porous heat exchange medium. The capillary tubes provide numerous small channels through which heat exchange medium can flow, dramatically increasing the surface area for heat transfer and enabling rapid temperature equalization throughout the container body
2Manufacturing precision
If multiple outlets are provided to reduce temperature difference, then temperature equalization improves, but device complexity and cost increase
Solution Approach 1:
The cooling function and container structure are merged into a single integrated body. The capillary tube cavities are formed directly within the container walls, combining the heat exchange function with the structural function, thereby eliminating the need for separate cooling outlets and complex piping systems while achieving superior temperature uniformity
3Productivity
If cooling is achieved by adhering evaporator or pipeline on back, then structure is simple, but heat exchange rate is slow and temperature equalization is poor
Solution Approach 1:
The heat exchange approach transitions from a two-dimensional surface contact (evaporator adhered to back wall) to a three-dimensional distributed network. The capillary tube cavities are embedded throughout the volume of the container body, enabling heat exchange to occur simultaneously across multiple dimensions and dramatically increasing the effective heat transfer area and rate

Function Achieved in This Case
The container achieves improved temperature equalization and heat exchange efficiency through rapid heat transfer, simplifying production and reducing costs by integrating capillary tube cavities and a micro-tooth structure within a heat-conductive material body.
Implementation Method 1
the inner wall of the capillary tube cavity being provided with a micro-tooth structure, and the heat exchange medium being capable of flowing in the capillary tube cavity along the extension direction of the capillary tube cavity
Implementation Method 2

AI summary
A temperature homogenizing container and a refrigerator having same. The container comprises a body and an accommodating space that is enclosed by the body. The body comprises several capillary tube cavities provided therein and allowing flow of a heat exchange medium. A micro-tooth structure is provided on the inner wall of each capillary tube cavity. The heat exchange medium may flow in the capillary tube cavities along an extension direction of the capillary tube cavities. By setting the container body to comprise several capillary tube cavities therein, the temperature homogenizing effect and heat exchange efficiency of the container are improved; by providing the micro-tooth structure, the heat exchange efficiency is further improved; the temperature difference of different areas in the container is reduced, and temperature homogenization in the container is achieved.
